I worked on these engines on the test cell at Kadena AB Okinawa Japan. It was neat to see one of these pigs run again but your video doesn't really show the noise that this engine makes. I have been underneath one of these on an open air test cell trying to read the variable vanes during a trim. The howl that came it made as the engine neared a target rpm was enough to make you physically sick and it did do that do me several times. The only engine that made more noise than a J-79 was J-58(SR 71 Motor). The first time I watched an SR 71 warm up it shook the ground enough at mil to vibrate me off the ground. Awsome!
In the early 80's, as a Marine Corps aircraft mechanic I worked for 6 months in an enclosed test cell called a "Hush House." In that building we accommodated entire aircraft to include A-4's (my birds), A-6's, and of course F-4's. Far and away one of the most memorable experiences of my life was standing 15 feet away from the F-4 as one of the engines (only one at a time) was put into full, 7-stage afterburner. The Gunnery Sergeant in the cockpit knew that I was new at the Hush House and slammed it into afterburner to scare the hell out of new Corporal (me) standing there in amazement. I will never forget my chest as it vibrated from the rumbling of that full AB. And if the awe for my body trembling trembling from sound waves wasn't enough, the 20 foot flame coming out of the engine was the icing on the cake. My words don't adequately convey the moment, and I know I'll never get to experience that again...INCREDIBLE.
I am a U.S. Air Force veteran. I served from 1977-1981. I was a jet engine mechanic working on Phantom F-4Es. This GE J79 is the engine for that aircraft. I well remember standing next to it when it went to full power and then to afterburner. And the date of this video, June 17th, is my birthday. Go figure!
That brings back some memories. I grew up near a AF base with an F-4 fighter wing. The daily roar of the J79 was a completely normal part of my childhood. The loudest noise I've ever heard in my life was watching 4 F-4's take off in formation with afterburners engaged. The noise was incredible and the ground shook like an earthquake.
I worked on the J79 in the F4 Phantom while assigned to VF-103 and went to A school as well as C School eventually becoming CER QUALIFIED. THIS ENGINE CAN TAKE A BEATING. One thing we were always taught was if the new engine did not have a slight leak from the Aux Air Door (81) send it back lol.
Great to see the brains behind the machine still active with commenters on the video even almost nine years later. The F-4 Phantom II and all the other aircraft this beast was mounted in were all worthy machines, and this loud chunk of supersonic thrust is a beauty. I can tell you and the gang take real good care of it.
When I was a kid in the 70's we lived on MCAS Yuma. There was a squadron of F-4's there. They would take off over base housing, afterburners on. It would shake the dishes in the cabinets. We were so used to it we didn't even pay attention to it. The good old days...
I began my aviation career working on these. They were utilized in the F-4 Phantom's. We also O/H'd the civilian version CJ-805 -3 & -23. They were used in the Convair 880 & 990 respectively.
Oh my! So as the vid ends..we Sailors on the flight deck called this the "fireplace" as we loved the Phantom returning to deck and warming us when in cold weather seas. I have a lump in my throat and tears in my eyes. Man, I miss my time in the Navy.
You know, after you fired off that afterburner, I was more than a little surprised that we didn't see your shop skootching along the ground with everyone chasing after it.
I am near the airport in Portland Oregon PDX often and once in a while the Air Force jets are taking off. It is indescribable the feeling of them kicking off the afterburners while taking off. Every car alarm within a mile is going off you feel it you chest and in your groin. Absolutely amazing piece of human technology.
Few years back, an F4 made it's way to Oshkosh. Sitting on the line next to a kid - probably 10yo - watching a national guardsman do his F16 demo, and the kid, responding to an afterburner pass, says, "Wow! That was loud." I told him, "Yeah, but wait till the F4 does his thing." When the time eventually came, and those twin J79s lit up, the kid turned to me, eyes wide, jaw literally dropped... I nodded in understanding.
I really like that story. I have seen many of these engine tests, and the AB always scares me. I think I know what's coming, but it seems I always forget.
I can tell you for a fact, it's incredibly loud. I worked on them in the service years ago. It will bring you to your knee's. The F-4 phantom has two of those engines, they would buzz our F-15 base in Germany during exercises, near the speed of sound so you wouldn't know they were coming until they were almost on top of you.
Yeah, your description is on key! As a former F-15E Crew Chief, there is no way to describe what its like to be next to a running jet engine in full AB. Its overwhelming and strikes you full of awe! You can scream at the top of your lungs and still not even hear your own voice. You can feel your internal organs shake. Great video man! It brings back memories of working with the last Wild Weasels during Desert Storm.
Yes, and as many people have refused to believe... that shaking is all caused by sound. The camera is of course not in the jet stream, but is off to the side. The volume of the noise is so high that it is dangerous. Not just to your hearing, but to all of you. Foamie ear plugs under ear defenders, and it's still too much. As you can see, it nearly shakes the camera apart.
@@AgentJayZ oh I believe you. I have performed maintenance over a huge transport helicopter engine. The thing was so loud we couldn't work in a hangar made out of riveted sheet metal. The whole building was resonating amplifying already deafening jet turbine roar.
Very cool I was a Dedicated crew chief and cut trained jets and hydraulics on the F4E/G Phantoms at George AFB Ca, 1986 till 1992 when we closed George and they moved to Nellis AFB for five more years I spent many long nights working, slaving and cursing those mighty J79-GE-17 !! IT WAS ALWAYS a love hate relationship but when you beat them gremlins it was such a great feeling like you could conquer the world and we did, I was the best damned F4 Phantom phixer that ever lived and thats not bragging it's a fact everyone I worked with and my pilots new me and damned proud of that honor. After I went 5o the kc135rt stratotankers where I had the pleasure of conquering another aircraft!! But that's another story.!!! Peace out and keep burning.
I used to fly the F-4E with 2 J79-17 engines. I believe 11,800 lbs thrust in military and 17,800 in full burner. 1000 lb per minute both engines in full burner. The aircraft weighed 31,250, With 4500 of fuel, about a 1:1 thrust to weight ratio. Now just a Model T used for target practice.
Hey David, X F-4 II VF-102 guy here.. There still are "flyable storage" ones in Tucson... a couple guys have been able to refurb them into "air show" displays.. there are a couple vids here on RUclips. Thank you for your service! VF-102 Diamondbacks Oceana, OUTSLANT USS Independence CV-62.
In A&P school we had a J47 off a B-47. We had it on a test stand. At power it would start pulling the anchors out off the ground and digging up the earth behind it. We also had a pretty good grass fire behind it. You guys must have one heck of an anchor system to keep it in place at full afterburner.
My most memorable afterburner experience was at an Air Show a few years ago watching a real rare bird, a Blackburn Buccaneer do a fly past, then at the second fly past the pilot hit the afterburners and put it into a steep climb......went like a bloody bat out of hell!! The sound was earth shattering!!
That would be cool to see. Maybe you saw a development prototype or something. My information is that the successful variants of the Buccaneer used the RR Spey, two of them, but without AB. Still the Spey is a very loud engine, and two of them would be making the equivalent of about 40 thousand Hp at takeoff power.
I used to run the test cells at Bergstrom in the 1980's, there is nothing like leak testing an engine in full afterburner. Can't describe fully what it feels to be next to it, but the feeling is still awesome. Thanks for the memories.
Stationed in Thailand, 388th Fighter Wing. Three squadrons of F-4Es, I can tell you how loud they get, 179 dB loud. It hurts your chest if you stand facing the rear of the aircraft when the burner is lit. It hurts so bad, you turn sideways to avoid it. No amount of hearing protection works. Spent the next two years in England on Bentwaters-Woodbridge Base, 81st fighter wing, F-4Ds. left the AF with a 30% hearing loss.
@@jamesmarlowe8231 I was there 1971-1972. I worked the last squadron of F-105F/G's in the 6010thm later changed to the 17th WW Squadron. They were no better noise wise.
I was at Korat the year of 1968. I worked the F105’s. Only one occasion did I work an F4. A sheared starter shaft…I dropped the starter but they arrived before the parts did! Someone else did the repair. Yes, those Thunder Hog 105’s were extremely loud too. That J75 in AB was too much!! You are so right. Ear protection couldn’t dampen all that racket! By the way, I did work the F4’s at Nellis AFB, and TDY at Davis-Monthan before Thailand. What a crazy 4 years of my life, but I’m glad I did it.
@@jamesmarlowe8231 I was Avionics, INS/Doppler. We were in for six active, for that year of schooling we got. I reupped early and did seven plus. But used that electronics training right up until I retired. It was worth the trip for seven years.
just taken a course on jet/rocket propulsion at the college i go to, and it's so cool to watch videos like this after taking such a course knowing what's generally going on behind the scenes. makes me even more in awe really. amazing video :D (also just gained yourself a sub)!
Currently revising exam coming up next week for turbomachinery module, learning about inlet and afterburning, and everything in between. I do agree that its quite cool to understand the general gist of what happening in that metal tube.
Absolutely, sir! The J79 weighs a ton and a half, burns 90 gallons per minute of jet fuel, and makes almost 9 tons of thrust. It's perfect for any beginners project in RC model making.
Nucking Futz! The camera shake during the AB and the sound is pure insanity. That's so much power in such a little space. Good to see you're still here 12 years later. Time travel FTW.
1973, USS Independence, RVAH-14 flying RA5C Vigilante. Twin J79's. I was a final cat-checker at launch. The roar was deafening. Now at age 70, my hearing is going.
72 was in Air Force Kunsan Korea. I was Munision Maint on F-4. Pulled safety flags at end of runway just b4 takeoff. Was very close to afterburners. So loud your body vibrated.
I was working on the F4F from 1998 to 2004. I have seen engine runs quite often. When the engines are installed in the airplane they are extreme loud. Its a sound you can feel in your bones and estomach. But when it is mountet on a dolly like in the video it is just brutal. It made me get sick. It was realy like someone kicking in your cheast. I loved it 😂. I miss working on the good old double ugly.
the reason is the intake of the jet engine on the jet itself dampens the sound in a good way cause it needs a special design for supersonic flight. if it is subsonic it doesnt need that special intake design so the sound is louder. the best example would be the harrier. it has a very very short intake and for this reason it must be very very loud
Back in the 70s I was stationed at Castle AFB. I worked for a time at the engine test cell. We had a cell for the j57 and one for the tf33. The TAC guys had their own for the j75 that went into the 106 Delta Dart. When that thing went into afterburner you could always tell because there was a momentary absence of noise then BOOM. We had a hut 50 feet away from the back of their cell. The calendar and anything tacked to the wall would stand away and coffee cups and anything not secured would just vibrate off. There was no conversation, all you had were your thoughts. Your body would vibrate the ground would vibrate chairs would move. It was like you were locked in and you had to ride it out. Then pffft gone the engine would throttle down and shut down. You were then free to go. You could hear that thing when we were running our own engine and it was just as dramatic. Last thing. I was running ground while we were testing a j57. A family came out, I guess their son mom and dad and a couple of little kids. I keyed into the booth and told them and to watch what happens. The were running a j75 and the family was watching everything in awe. I turned my back on them and waited for the j75 to go ab. When it did they all thought there was an explosion and hit the ground. I was standing there with a smile and pointing at them. I had some good times on that cell.
Pretty cool. And imagine, an F4 Phantom used 2 of those babies and these engines are from late 1950’s early 60’s. Pretty impressive or at least for me.
Absolutely fascinating! I used to work for Allied Signal (before Honeywell bought us) and used to watch every engine test I could get time (and space, and clearance) to see, from commercial to military... but I have NEVER seen an afterburner demo! Too much power for our facility, that was done at a remote facility that I had neither the time nor clearance to enter. Thanks for posting these videos. You've got a new Subscriber!
Served on the Forrestal with RVAH-13. Working nights as a cat checker standing between a Vigilante and a Phantom on #1 and #2 catapults in full AB, then you know what noise and vibration is!
Although I never got to work/run the J79 engine (before my time) I have worked on/ran the PW-F100-220/229, the GE F110-100/129 and my favorite one so far, the F119-PW-100. the amount of power you feel coming off a turbo fan jet engine and max AB is literally breath taking.
I watched the the Thunderbirds at an airshow a couple of times in pocatello Idaho the first time the observer line was close and it was so freaking loud you felt it in your chest as they took off at full afterburner...the second time however they move the line a considerable distance back sill loud but not near as bone rattling, however we were treated with a high speed low pass of a B1 bomber at full afterburner which seemed to shake the earth. Great show it was I'll never forget it....nice demonstration of your engine I can relate to some degree 👍btw.
That's a ten ton engine pulling on a 100 ton mount. Byron measured how much it moves. .025, or one fortieth of an inch. This test cell handles about 50 engines every year, so we built it to take it.
Many years ago I visited my brother on base when he was in the air Force. While we were there they were launching several B-52s and even though they must have been more than a mile away you could feel the house rattle.
B-52 generally my aren't bad on the base. There used to be a place you could pull off the highway off the end of the runway that was on Griffiss AFB. It was close enough that they would still have their landing gear down and they would be unbearable loud.
As a USAF crew chief, the guy without ear protection drives me crazy. I had a guy lose a filling from a tooth during an F-16 engine run. So he’s either already completely deaf or completely insane.
The shot was taken at idle. These magic things called hands can block out a lot of sound when it gets louder. Not convenient, and hey, I am not his mother. But for a spectator, you don't really need hands, right? Also, it was a long time ago, and I think he may have had earplugs in. It's so loud, as you know... that I use ear plugs under ear defenders when I am back there...
@Zfast4you is it not possible for you to know there was a time when RUclips was for people who wanted to share something entertaining or interesting without having a singular monitary agenda behind it? Without having to install ad blockers that also cost Money? GREED GREED GREED. It shall be humanities demise.
Having experienced F18's take off from the deck the Afterburner really makes it hit in your chest Just a raw roar and it's much more high pitched until they light the burner
That's awesome! "Newly rebuilt" huh? That's neat. I'm always thrilled when I change the oil and spark plugs on my vehicle and it still works after. Thanks for creating the video. When I was 12, my next door neighbor was fresh out of the Air Force and was a jet engine mechanic though I'm not sure which specifically. He had a picture on a shelf of a test burn like yours but at night. It was so cool. He became our neighbor 'cause after service he got a job at Aerojet in Rancho Cordova. That was back in '85 and there was nothing between but grassy fields and Mather Air Force Base. On very calm Saturday mornings, you could hear long burns of jet engines. I always wondered if it was from the base, 8 miles or Aerojet, 15 miles. Mather is only 8 miles so that's more likely, I'd think. Again that was back when Mather was an active military base so any day you could see B-52s or F-4 Phantoms (a childhood favorite + F-14 = drool) among many other aircraft. Before I go, well into adulthood, around the early 2010s, I found out that the lifelong neighbor on the other side was an engineer on the F-117!!! No one had any idea. He looked like of the drawings from the old Herman comic strip. Asked about work he'd say vaguely that he was an engineer of some kind then ramble some ridiculously technical mumbo-jumbo (nothing aerospace sounding though) and change the subject. It was probably a scripted response given the extreme top secrecy of the project. Well, thanks for the vid, sorry I'm so wordy, I love all things aviation, just never had the aptitude to do anything with it.
Used to run these at night on an open air test bed and get the turbine section so hot that sometimes you could see a spot where you could see the turbine blades turn.
Thank you for these - it's greatly appreciated. I remember the noise of an f16 going afterburner whilst banking away from the crowd at an airshow when I was a kid; the sound is hard to explain, I felt it in my chest more than heard it through my ears. Unbelievable stuff!
My Dad was a Navy F-4 Pilot in Nam and afterwords at China Lake Ca. To this day I cannot imagine the balls needed to strap yourself in front of 2 of these J-79’s. (Funny side note: the base had a large pool near the runways, My dad buzzed our little Ford Station wagon with Afterburners on! Scared the crap out of mom, Me and my Brother loved it, but it felt like the car was gonna flip over... lol)
Homefront please thank your dad for his service. You speak of having balls to strap on two of these engines. Now imagine riding them to downtown Hanoi with the whole sky lit up with AAA. That’s a very large pair indeed...
I might need to buy one of these. When I'm driving and one of those ghetto fabulous dudes with subwoofers thinks he's cool booming everybody at the light, I just switch on the J79, say "I got something for you mang!", kick on the burner, "whatchoo think about my bass mang!!" Yes. I think this is the winning ticket right there.
A lot of comments recently. It's like YT suddenly decided 'this needs to be seen'. I can only agree. Having been near these things, I can almost feel my internal organs melting at the earth shaking sound levels again. Watching a B1B at just-over-your-head levels in burner makes the world shake.
I used to be lucky enough to be able to stand behind Concord at Heathrow airport.......on the boundary fence......that was LOUD!!!! 4 Olympus with full after burn!!!!..... I would say difference between with and without after burn is like a Street pro on a drag strip then a Top fuel goes past and life stops for a split second.... great filming and thanks for putting on RUclips.....
"Modern" HAHAHAHA this was state of the art in 1955 its a 65 year old design a more modern engine design makes 8000 lbft more thrust than the afterburner on this while dry, and even that is a 20 year old engine
If someone was like using bose headfones with noisecancellation (cancels nois from outside and lets you only hear the thing) im pretty sure that #rip eardrums with full volume
I worked on GE J79 for many years. It is hard to R&R the AB ignition switch when the engine is installed in the F-4 A/C. I started working on them in 1977.

Still the Spey is a very loud engine, and two of them would be making the equivalent of about 40 thousand Hp at takeoff power.
Buccaneers are great, they do not have afterburners though
I used to run the test cells at Bergstrom in the 1980's, there is nothing like leak testing an engine in full afterburner. Can't describe fully what it feels to be next to it, but the feeling is still awesome. Thanks for the memories.
It really is something else. You can feel the vibrations in your sinuses.
Was at Bergstrom in the late 80's and worked on the F4 and was engine run qualified miss that sound.
Stationed in Thailand, 388th Fighter Wing. Three squadrons of F-4Es, I can tell you how loud they get, 179 dB loud. It hurts your chest if you stand facing the rear of the aircraft when the burner is lit. It hurts so bad, you turn sideways to avoid it. No amount of hearing protection works. Spent the next two years in England on Bentwaters-Woodbridge Base, 81st fighter wing, F-4Ds. left the AF with a 30% hearing loss.
I was in the 388th at Korat. I was there when the first F4’s arrived. I too lost some hearing (engine mechanic)
@@jamesmarlowe8231 I was there 1971-1972. I worked the last squadron of F-105F/G's in the 6010thm later changed to the 17th WW Squadron. They were no better noise wise.
I was at Korat the year of 1968. I worked the F105’s. Only one occasion did I work an F4. A sheared starter shaft…I dropped the starter but they arrived before the parts did! Someone else did the repair. Yes, those Thunder Hog 105’s were extremely loud too. That J75 in AB was too much!! You are so right. Ear protection couldn’t dampen all that racket! By the way, I did work the F4’s at Nellis AFB, and TDY at Davis-Monthan before Thailand. What a crazy 4 years of my life, but I’m glad I did it.
@@jamesmarlowe8231 I was Avionics, INS/Doppler. We were in for six active, for that year of schooling we got. I reupped early and did seven plus. But used that electronics training right up until I retired. It was worth the trip for seven years.
I work the e' and d,s at Lakenheath eor. Then the 111,s eor. I do miss it.
just taken a course on jet/rocket propulsion at the college i go to, and it's so cool to watch videos like this after taking such a course knowing what's generally going on behind the scenes. makes me even more in awe really. amazing video :D (also just gained yourself a sub)!
Welcome to Jet City!
Currently revising exam coming up next week for turbomachinery module, learning about inlet and afterburning, and everything in between. I do agree that its quite cool to understand the general gist of what happening in that metal tube.
I‘m in rc planes for 2 weeks now.
And i was wonderling if that engine is good for beginners
Absolutely, sir! The J79 weighs a ton and a half, burns 90 gallons per minute of jet fuel, and makes almost 9 tons of thrust. It's perfect for any beginners project in RC model making.
AgentJayZ ok thanks! Can i buy it on amazon?
You'll want something more powerful after the first time you fly it......
Peter Plassmann yeah but everyone have to start somewhere🤷🏼♂️
Would look forward to see you cross an ocean, as the french jetboarder did with the smaller model jetengines and the english channel..
Nucking Futz! The camera shake during the AB and the sound is pure insanity. That's so much power in such a little space. Good to see you're still here 12 years later. Time travel FTW.
1973, USS Independence, RVAH-14 flying RA5C Vigilante. Twin J79's. I was a final cat-checker at launch. The roar was deafening. Now at age 70, my hearing is going.
Made me worried those guys watching with no ear protection...
72 was in Air Force Kunsan Korea. I was Munision Maint on F-4. Pulled safety flags at end of runway just b4 takeoff. Was very close to afterburners. So loud your body vibrated.
MrPepper312 In '72 I began building J79's for Phantoms. Awesome memories.
How do you just have this in your garage lol
Who doesn't
Its not his garage lol, this is his company workshop
This is a test building, they ain’t putting them together in there
It’s like millions of dinosaurs roaring together, o wait isn’t that jet fuel made from...
)))))
It's their souls getting burn in hell
In a few million years, we'll end up just like them too.
I was working on the F4F from 1998 to 2004. I have seen engine runs quite often. When the engines are installed in the airplane they are extreme loud. Its a sound you can feel in your bones and estomach. But when it is mountet on a dolly like in the video it is just brutal. It made me get sick. It was realy like someone kicking in your cheast.
I loved it 😂.
I miss working on the good old double ugly.
the reason is the intake of the jet engine on the jet itself dampens the sound in a good way cause it needs a special design for supersonic flight. if it is subsonic it doesnt need that special intake design so the sound is louder. the best example would be the harrier. it has a very very short intake and for this reason it must be very very loud
Back in the 70s I was stationed at Castle AFB. I worked for a time at the engine test cell. We had a cell for the j57 and one for the tf33. The TAC guys had their own for the j75 that went into the 106 Delta Dart. When that thing went into afterburner you could always tell because there was a momentary absence of noise then BOOM. We had a hut 50 feet away from the back of their cell. The calendar and anything tacked to the wall would stand away and coffee cups and anything not secured would just vibrate off. There was no conversation, all you had were your thoughts. Your body would vibrate the ground would vibrate chairs would move. It was like you were locked in and you had to ride it out. Then pffft gone the engine would throttle down and shut down. You were then free to go. You could hear that thing when we were running our own engine and it was just as dramatic. Last thing. I was running ground while we were testing a j57. A family came out, I guess their son mom and dad and a couple of little kids. I keyed into the booth and told them and to watch what happens. The were running a j75 and the family was watching everything in awe. I turned my back on them and waited for the j75 to go ab. When it did they all thought there was an explosion and hit the ground. I was standing there with a smile and pointing at them. I had some good times on that cell.
Donald Scheibener thank you for your service!

Pretty cool. And imagine, an F4 Phantom used 2 of those babies and these engines are from late 1950’s early 60’s. Pretty impressive or at least for me.
Absolutely fascinating! I used to work for Allied Signal (before Honeywell bought us) and used to watch every engine test I could get time (and space, and clearance) to see, from commercial to military... but I have NEVER seen an afterburner demo! Too much power for our facility, that was done at a remote facility that I had neither the time nor clearance to enter.

Served on the Forrestal with RVAH-13. Working nights as a cat checker standing between a Vigilante and a Phantom on #1 and #2 catapults in full AB, then you know what noise and vibration is!
Thank you for your service,not to mention being in one of the most dangerous jobs on the planet!
Although I never got to work/run the J79 engine (before my time) I have worked on/ran the PW-F100-220/229, the GE F110-100/129 and my favorite one so far, the F119-PW-100. the amount of power you feel coming off a turbo fan jet engine and max AB is literally breath taking.
They should give you a nobel prize for your education efforts to humanity! Thank you.
I think that's way too extreme, but thanks for thinking that way.
@@AgentJayZ from my heart.

I'm surprised that building doesn't just collapse in on itself. You know the barometric pressure inside the building must be dropping.
Ah, I see you are a man of culture as well.
(the building doesn't collapse because the drop in pressure is holded (mostly) by the engine)
Hence why the two doors are opened🙃
Only If it were a closed system and there was enough suction pressure from the intake
I watched the the Thunderbirds at an airshow a couple of times in pocatello Idaho the first time the observer line was close and it was so freaking loud you felt it in your chest as they took off at full afterburner...the second time however they move the line a considerable distance back sill loud but not near as bone rattling, however we were treated with a high speed low pass of a B1 bomber at full afterburner which seemed to shake the earth. Great show it was I'll never forget it....nice demonstration of your engine I can relate to some degree 👍btw.
This is the type of "recommended" i want from RUclips ! Nice !
*_Still quieter than my computer fan._*
Let me guess, 80mm howler? :))
XD TRUE
I can picture the mount pulling out of the floor and the whole thing firing itself down the interstate.
That's a ten ton engine pulling on a 100 ton mount. Byron measured how much it moves. .025, or one fortieth of an inch.
This test cell handles about 50 engines every year, so we built it to take it.
Many years ago I visited my brother on base when he was in the air Force. While we were there they were launching several B-52s and even though they must have been more than a mile away you could feel the house rattle.
B-52 generally my aren't bad on the base. There used to be a place you could pull off the highway off the end of the runway that was on Griffiss AFB. It was close enough that they would still have their landing gear down and they would be unbearable loud.
f 14 mech here , i can remember standing between cats 1 and 2 with 2 birds in afterburner sound made it hard to breath
vf 142 on the ike
The back camera is probably screamin DAAAAMMN!!
As a USAF crew chief, the guy without ear protection drives me crazy. I had a guy lose a filling from a tooth during an F-16 engine run. So he’s either already completely deaf or completely insane.
The shot was taken at idle. These magic things called hands can block out a lot of sound when it gets louder. Not convenient, and hey, I am not his mother. But for a spectator, you don't really need hands, right?
Also, it was a long time ago, and I think he may have had earplugs in. It's so loud, as you know... that I use ear plugs under ear defenders when I am back there...
@@AgentJayZ wow its cool after 9 years buddy is still replying good work!
Used to park at the end of the runway at El Toro and watch the F4's take off with full AB, it was awesome!
Thank's for the video.
The other end of the hold down bolts have to be periodically torqued down by some guy just outside of Beijing
That’s a pretty cool r

The loudness will mess with your heartbeat.
Well, that is the most effective way of blowing leafs I've seen so far.

Still terrific video even after all these years. Love the matter-of-fact manner in which you explain how these marvels of machinery do what they do.
....and as a result of this J79 run, the earth's day was shortened by 14 minutes and 52 seconds.

Having experienced F18's take off from the deck the Afterburner really makes it hit in your chest Just a raw roar and it's much more high pitched until they light the burner
The jet gave the grass a soil fade. Fresh trim
Your neighbors must love you.
A very common comment. One of the most common of all. No neighbors... so...
@@AgentJayZ You know we're kidding, right?
How much are they must have ab.
That is one super strong tripod.
That's awesome! "Newly rebuilt" huh? That's neat. I'm always thrilled when I change the oil and spark plugs on my vehicle and it still works after. Thanks for creating the video. When I was 12, my next door neighbor was fresh out of the Air Force and was a jet engine mechanic though I'm not sure which specifically. He had a picture on a shelf of a test burn like yours but at night. It was so cool. He became our neighbor 'cause after service he got a job at Aerojet in Rancho Cordova. That was back in '85 and there was nothing between but grassy fields and Mather Air Force Base. On very calm Saturday mornings, you could hear long burns of jet engines. I always wondered if it was from the base, 8 miles or Aerojet, 15 miles. Mather is only 8 miles so that's more likely, I'd think. Again that was back when Mather was an active military base so any day you could see B-52s or F-4 Phantoms (a childhood favorite + F-14 = drool) among many other aircraft.
Before I go, well into adulthood, around the early 2010s, I found out that the lifelong neighbor on the other side was an engineer on the F-117!!! No one had any idea. He looked like of the drawings from the old Herman comic strip. Asked about work he'd say vaguely that he was an engineer of some kind then ramble some ridiculously technical mumbo-jumbo (nothing aerospace sounding though) and change the subject. It was probably a scripted response given the extreme top secrecy of the project.
Well, thanks for the vid, sorry I'm so wordy, I love all things aviation, just never had the aptitude to do anything with it.
7:13 when my pc runs any Minecraft shader for more than 1 minute
This would be great for crowd control
Would love to see this engine being run at night. It would be awesome to see the afterburner light up the area at night.
Used to run these at night on an open air test bed and get the turbine section so hot that sometimes you could see a spot where you could see the turbine blades turn.
Eng RUN UP IN TRIM PAD POINT ON THE NIGHT REMEMBER🤩
Thank you for these - it's greatly appreciated.
I remember the noise of an f16 going afterburner whilst banking away from the crowd at an airshow when I was a kid; the sound is hard to explain, I felt it in my chest more than heard it through my ears. Unbelievable stuff!
My Dad was a Navy F-4 Pilot in Nam and afterwords at China Lake Ca. To this day I cannot imagine the balls needed to strap yourself in front of 2 of these J-79’s. (Funny side note: the base had a large pool near the runways, My dad buzzed our little Ford Station wagon with Afterburners on! Scared the crap out of mom, Me and my Brother loved it, but it felt like the car was gonna flip over... lol)
Homefront please thank your dad for his service. You speak of having balls to strap on two of these engines. Now imagine riding them to downtown Hanoi with the whole sky lit up with AAA. That’s a very large pair indeed...

I might need to buy one of these. When I'm driving and one of those ghetto fabulous dudes with subwoofers thinks he's cool booming everybody at the light, I just switch on the J79, say "I got something for you mang!", kick on the burner, "whatchoo think about my bass mang!!" Yes. I think this is the winning ticket right there.
Afterburner is so loud, got to see some f15s flyby with and without, super quiet without, and absolutely blasted away with. So awesome.
I used to fly F-14A's and had two TF-30 after burning engines. The later model, F-14D, had GE F-110 engines and were about 50% more powerful.
Everybody in the house: *sleeps*

Lots more noise and mayhem... right up to last week!
A lot of comments recently. It's like YT suddenly decided 'this needs to be seen'. I can only agree. Having been near these things, I can almost feel my internal organs melting at the earth shaking sound levels again. Watching a B1B at just-over-your-head levels in burner makes the world shake.
I used to be lucky enough to be able to stand behind Concord at Heathrow airport.......on the boundary fence......that was LOUD!!!! 4 Olympus with full after burn!!!!..... I would say difference between with and without after burn is like a Street pro on a drag strip then a Top fuel goes past and life stops for a split second.... great filming and thanks for putting on RUclips.....
I think this the ultimate “R.I.P headphone users” video! It’s insane how much power is in modern jet engines!
"Modern" HAHAHAHA this was state of the art in 1955 its a 65 year old design a more modern engine design makes 8000 lbft more thrust than the afterburner on this while dry, and even that is a 20 year old engine
@@zacht9447 Still you get what I mean. It might be old compared to jet engines now, but it's still modern technology haha
i think the way the camera vibrates at 5:10 says all you need to know about how loud this thing is
Rip mic and earphone users
If someone was like using bose headfones with noisecancellation (cancels nois from outside and lets you only hear the thing) im pretty sure that #rip eardrums with full volume
I worked on GE J79 for many years. It is hard to R&R the AB ignition switch when the engine is installed in the F-4 A/C. I started working on them in 1977.
Ignition switch hard, try doing the throttle quadrant or even better dropping in the rig pins.
I left gallons of blood on these.
Loved it😎💣
That is truly awe-inspiring power. Watching the camera shake and the exhaust go red made me truly happy that i decided to go into aerospace.
