This a General Electric J-79-15. The J-79 Series of engine powered the B-58 Hustler, F-4 Phantom and even the Early FMS F-16's. It is a 16 Stage axial-flow Afterburning Turbo-jet, with 3 stages of Turbine. Depnding on the (-) model thrust would vary from 15,000 to 17,500 lbf/lb
@Slipkid427 Uh, thanks for that... Actually there are 17 stages of compression in all J79s, and this particular one is what's known as an OEL-7. It was license-built in Canada by Orenda to power the Canadian Starfighter, known as the CF-104.
It is currently installed in an F-104 flown by the Starfighters airshow demonstration team in Florida.
My God man! That is awesome! I just built a homemade jet engine for my Senior Design project for engineering school. Check out the video I just uploaded and tell me what you think! Now if it could only get me a job bc I graduate in 2 weeks haha
The noise from that motor is so disturbing and the strange part is, I really love it. At least here on the computer where I can turn it on or off when I want. If I had to listen to it while trying to sleep, concentrate, study, read, I'd probably loose my mind in a short time because it is a bit too much for the brain to handle.
Do you have an idea of how long one could run a motor like this at full afterburner before it blows up? Do they overheat or over vibrate...when you run them at full afterburner? Is there a recommended duration for full afterburner which should not be exceeded...? Your comments on this topic please?
Is there a static type/bench test that you do to test the opening and closing of the tail feathers with the motor off? I Would love to see a video of them working opening and closing up close and personal and an explanation of how they work.
@sanfranciscobay We don't do such a test. The way they work is basically explained in your snot story.
It's not called the venturi effect. It's adjusting the size of the orifice through which a volume of gas is passing in order to maximize acceleration of the flow.
Heat the gas up, and it takes up more volume, so the best orifice size is bigger. AB makes the exhaust hotter, so the nozzle is bigger.
I have an example of why the tail feathers close up when afterburner is on to improve thrust.
I just got over a cold, that has lasted for 2 weeks, where I've had to blow my nose, 20-30-40 times per day. When my nose got so stuffed up and I wanted to clear it, I would take a tissue, and blow the mucous into the tissue. But in order to get the mucous out, I would reduce the size of the opening of my nostrils, then blow. That method seemed to work the best. I think it's called the Venturi Effect?
Here's a question: Why is there a difference in sound, where the pitch seems to get higher at about 1:29 (you say it's been in full power for at least a few seconds) and then it seems to change in pitch to a lower louder roaring sound from 1:45-1:58. Can you explain why the sound is changing at 1:29 and 1:45?
@sanfranciscobay This is an old video, posted before I could edit quicktime movies, and all the shaky footage at the beginning I never really wanted in there. I just watched it now, and the sound does change where you say. I'm not sure about the louder raoring sound, but that may be a slight throttle down.
This engine had problems we were working out, but it also had a progressive afteburner.
Do they make specialized hearing protection or clothing that would allow a person to stand 5-10-20-40-80 feet away so they would be in the loudest area staying clear of the heat and high winds? What are the effects of this type of noise on the human body at close range? How much hearing protection can a person get? How much can the human body take?
In my other vids on afterburners, I'm about 50 feet away.
The noise from an afterburner at that distance is not describable.
You feel it more than hear it.
Your ears, with double hearing protection, are maxed out before afterburner is engaged. When AB is on, it feels like your body is being shaken apart, but I'm sure it could take quite a bit more. How much? Who knows.
I have a question re a triple powered turbine truck called Shock Wave that attends air shows. The video is below. During the video, you will see big flame bursts and white steam from the tail along with some popping sounds. What is causing the engine to flame, steam and pop? Thankyou
@sanfranciscobay Please keep this in mind: a jet truck has only one purpose, and that's to entertain. There are many ways to exploit a jet engine to burn fuel, make fire, and look impressive. Many of the systems used by shockwave do not exist in aircraft engines or industrial turbine engines.
ONE of the things Shockwave does with jet fuel is burn it in a fixed-nozzle afterburner tuned for best thrust at max flow.
That means at full, non AB power, the engines make very little thrust.
@sanfranciscobay This is why, even to get to the staging line, the driver has to use short blasts of the afterburner. The very first aircraft with AB used a two-position nozzle. One position for max military power, and a larger outlet for that plus afterburner. The J79 has a progressively variable nozzle, which you see eventually working properly in this video.
Jet cars and trucks have a nozzle fixed to one outlet size.
All the other flames and fuel mist displays are for show.
That is just so way too cool. Do you ever have rock and roll bands, free unlimited beer on tap, barbque and then fire up the motor for a grand finale? That's just so insane.
Is it possible to have neighbors with noise like that?
@sanfranciscobay Well, a lot of us would like that, but this is a test of a customers engine at a company specializing in gas turbine overhaul.
You can't party all the time.
We do have a couple of our own engines, though... and if maybe someone wanted to organize a long-weekend , burning man sort of thing... it might just work.
@AdelineProductions Nothing to him, He reapair old beat engine's namely the j-79 and converts them to LM1500's An industrial power plant, Hes working on an afterburning J79 right now and he might have HD video of this in a month or so!
@AdelineProductions Well, since you live in the states, it's easier. We could set you up with an afterburning J79 for somewhere north of a quarter mil in US dollars.
Love that Howl of the J-79 engine I remember when the US Navy flew the F-4 Phantoms in the early 70;'s when they flew over my house the first time I ever heard one I ran inside scared to death they were heading to NAS Kingsville for an air show.
@CaptainTattyBoJangle Our closest neighbors are across the street. Their three daughters are always bringing over baking for us - usually cookies that are still hot.
@CodenameWhistler00 I'd take a J79 or two...as long as it's installed in an F-104 or a F-4! Not much point in burning all that fuel just so you can roast marshmallows from 100ft away!
Take a look at any steel frame building. The frame holding the engine is fabricated out of what is commonly called "structural steel". It's bolted together with the high-quality bolts that any ironworker would instantly recognize a mile away.
The only wrench you need is inch and an eighth...
Hmm if it howls, with out being inside the aircraft... then its proof it is not the aircraft intake! probably cud be the engine nozzles :/
One thing, most of the times how much throttle are you using? 60%/military power? In this video it howls at times and others it doesnt howl :s Is it because you changed throttle?
Its weird! Ive seen many F104 vids... sometimes they howl, sometimes they dont :s
Well, what we call full military power is max throttle without afterburner.
That is the setting we notice makes the most howling noise.
The afterburner causes the nozzle to open, and a great deal more fuel is burned, but it is injected after the last stage of the turbine, so the engine does not turn any faster in AB.
This engine seems to howl between 95-100% throttle.
@AgentJayZ Don't mean to butt in, but maximum "howl" is around 70-80% Above this, the "howl" goes away, and below this, it's gone too. You can hear this in the video when the engine throttles up, the howl comes and then dissappates when the throttle is opened to 100%. The noise seems to be coming from the short tailfeathers unique to the older 104 units. The early F4 and later "long" tailfeathers do not howl. Also, the old 104 nozzles are straight converging. The newer ones are con-di.
thats such a freakishly awsome howl that this model of engine makes, going through the throttle range, thanks S&S for getting these great old engines back into 104s for our kids to see someday, great work!
theorically you are right , but I remember that just to start moving taxying you needed to set 83% of power. You didnt have any flight idle setting.The flight idle device is only for boring airline planes with turbofan engine very slow in speeding up so not to compromize the go around capability. This was a splendid full jet engine speeding up from idle to full A/B in a couple of second. It was a splendid engine and flying the F104 was better than screwing any woman in the world , trust me.
Oooops... sorry, I goofed and you're right: chopping to idle would keep the nozzle open; while if you just cancel AB and go back to military it would close again.
PS: I can't remember any such thing as a "flight idle" on a 104 which needs to land with a pretty brisk throttle (70%?)in order to maintain the flap blowers on!
On snap decel to idle, the nozzle will stay open. Check the other j79 vid AgentJayZ has up recently, the same thing happens. Yes we have -19 units here too!
This unit is a Canadian built version of the J79, an Orenda OEL-7. We've run a -11 on full 'burner too, for the North American Eagle-II land speed record attempt car.
Given a (within reason) worst case malfunction, while under test on the stand, what would you expect to see occur? Would the damage be mostly contained within the engine structure? Or the disquieting possibility of flying parts?
Ok, all you J79 freaks. First, you want to see my video about the training on the F-104, which I enjoyed so much at Luke AFB / Arizona in 1967 and 1968. All German F-104 pilots were trained during those years on T-37 and T-38 at Sheppard AFB, Texas and then at Luke AFB, where we flew the F-104 for about 120 hours. Back in Germany: further training until combat ready. Normal low level cruising speed was 450 knots, at 38.000 feet: mach 0.96. The burner gave a nice kick in the a.. wbeeck (Buddy)
Great "original" sound, which all former F-104 pilots love to hear again... (hold the camera still next time...) I flew the F-104 myself for many years for the german Navy (1./MFG2) and still find this paticular sound of the J79 engine absolutely unique. Also: see my own F-104 video under wbeeck, if you like...
That HOOT sound the J-79 makes on throttle up sure brings back memories. (F-4) Is it the nozzle restricting that causes that? What a great job you got!
I've seen the Starfighters F-104. Awesome paint scheme and amazing to watch fly by even at subsonic speeds. Guess you guys built a good engine. I've also got some footage of a J-79 powered Semi truck firing the afterburners from about 20 away. What a sight to behold.
Awesome vid!!Weren't they going to put a pair of J-79's in the Avro Arrow? When was the first J-79 made?I used to live down the street from Orenda in Malton.
I really only want a downrated J-79. I don't have a use for a mach 2 powerplant. Do J-79's exist with a reduced spool. LIke 7 compressor stages instead of 17. I have already designed a machine for one J-79 but it is just transonic. I won't need a powerplant rated for 2x mach.
I don't want a flight rated engine. I want a heap so I can counterfit the parts. The licence is up on the J-79. Anything goes. I don't want a J-47 or a J-57. I want a J-79 because it has higher production volume. I know that the J-79 was built in volume with a reduced a comp. spool. Theres a model for pumping natural gas that only has a four stage comp. There's also turbo shaft variants with a smaller spool. I have good facilities. If I have one set of parts, I can make more.
I found out about the variants from the Generel electric site. Where are you getting 'your' info? There are versions of the J-79 that run on a portion of the natural gas they are pumping inside the line. There are more variants than three. You seem to be hung up on the F-104 powerplant like it's the only version of J-79 that exists. Why?
As for a turboshaft J79, The only thing I know of that comes close is an LM1500 coupled to its power turbine. This is a separate piece of equipment, and its output is a rotating shaft of approx. 17,000 Hp.
Just 'cause I've never seen 'em doesn't mean they don't exist. Put some pix up, OK?
My schedule is too busy for an extended recon mission for scrouge worthy hardware right now. I have been vlogging lately. Check out my channel. I am the epitome of speading myself too thin.
The J-79 is always the same diameter. I am reffering to the variants, or more properly the derivitives of the J-79. The thing that makes the J-79 and the derivitives special is the single spool and variable inlet stators. About every GE turbine powerplant has about the the same combustion and power turbine section. The turbofan and turboshaft units just have an added spool to this core.
I want to find a wrecked J-79 so I can copy the parts. I want to build one with a shortened spool.
They made an exposed fan engine for Candair out of a short spool J-79.
The J- 79 is the traditional flagship of the GE aircraft powerplant line. The J-79 parts have been produced in many scales and appear in GE products today.
The parts are not interchangeable, only the form is the same. Every one of parts have a lot of engineering. They get everything out of them.
Hell yes I will haul away some J-79 parts.
My facilities are in upgrade right now. I have to wait. I will keep in touch.
Yes, it must be incredible to sit on top of one of these and open it up.
This test took place on a hot summer day, and it was impressive to feel the world shake. The video doesn't really reproduce even a hint of the fury and mayhem these things put out.
This engine is now flying in a Starfighter F-104.
The F-4 Phantom II had two of them.
The only aircraft I know of with 4 afterburning J79s was the Convair B-58 Hustler.
damn talk about raw power . i lived near andrews air force base when i was growing up and remember hearing the howl these engines made when F4 phantoms and 104 starfighters flew by overhead . awesome
If you do a bit of research on the history of the J79 and the f-104 Starfighter, you'll see that your question has many answers, depending on who you talk to.

sanfranciscobay 1 year ago
@sanfranciscobay The engine does not experience any additional stress while employing the afterburner.
AB use is kept to a minimum because of the massive increase in fuel consumption it causes.
Basically the engine is running at full rpm and power... then you spray fuel into the exhaust and light it.
Change in conditions for the engine proper: none

That is an excellent question. Unfortunately I don't have an answer.
We have been told by some air force types who worked with F-104s that it is the nozzle.
I can say from my personal experience that the howl sounds the loudest when I'm off to the side of the engine.
It's less noticeable when I'm in front of, or behind the engine.
But then, when you are within 50 yards of the thing, it's really hard to tell whats loud and whats really loud, because it's all over-the-top loud...

I have another AB video of another J79, and more is on the way.
Flight idle is not a whole lot of thrust, and ground idle is zero thrust.
Give or take a hundred or so.
AgentJayZ 2 years ago
theorically you are right , but I remember that just to start moving taxying you needed to set 83% of power. You didnt have any flight idle setting.The flight idle device is only for boring airline planes with turbofan engine very slow in speeding up so not to compromize the go around capability. This was a splendid full jet engine speeding up from idle to full A/B in a couple of second. It was a splendid engine and flying the F104 was better than screwing any woman in the world , trust me.

Oooops... sorry, I goofed and you're right: chopping to idle would keep the nozzle open; while if you just cancel AB and go back to military it would close again.
PS: I can't remember any such thing as a "flight idle" on a 104 which needs to land with a pretty brisk throttle (70%?)in order to maintain the flap blowers on!

Terrific work guys!!!
Your engine must be a GE-11 version, with the typical howling nozzle, while ours on F104S were GE-19, with a different nozzle and no howl at all.
By the way, why did your nozzle stay wide open after reheat shutdown???
I spent about 30 yrs around 104G's and S's, not flying but doing most of the rest!
Keep up with the good work guys!!!
papy1446 2 years ago
The test requires ramping the throttle from idle to full AB within one second, and then back to idle.
It may be ground idle, and not flight idle.
I'm not the driver, but I'll try to find out
AgentJayZ 2 years ago
On snap decel to idle, the nozzle will stay open. Check the other j79 vid AgentJayZ has up recently, the same thing happens. Yes we have -19 units here too!

This unit is a Canadian built version of the J79, an Orenda OEL-7. We've run a -11 on full 'burner too, for the North American Eagle-II land speed record attempt car.

Given a (within reason) worst case malfunction, while under test on the stand, what would you expect to see occur? Would the damage be mostly contained within the engine structure? Or the disquieting possibility of flying parts?

Ok, all you J79 freaks. First, you want to see my video about the training on the F-104, which I enjoyed so much at Luke AFB / Arizona in 1967 and 1968. All German F-104 pilots were trained during those years on T-37 and T-38 at Sheppard AFB, Texas and then at Luke AFB, where we flew the F-104 for about 120 hours. Back in Germany: further training until combat ready. Normal low level cruising speed was 450 knots, at 38.000 feet: mach 0.96. The burner gave a nice kick in the a.. wbeeck (Buddy)

Great "original" sound, which all former F-104 pilots love to hear again... (hold the camera still next time...) I flew the F-104 myself for many years for the german Navy (1./MFG2) and still find this paticular sound of the J79 engine absolutely unique. Also: see my own F-104 video under wbeeck, if you like...
Greetings to all ex- F-104 jockeys,

If you flew an F-104, then you are just the guy that I , and I think a lot of people, want to hear from!
This engine is out of an F-104 that flies with the Starfighters demo team in Florida.
The footage was taken at quite a distance by Dave, a ground crew member of that team.
They had their engine tweaked and tested up here at S&S Turbines.
Please describe what it's like to fly that hotrod, and what the afterburner does to that feeling...

That HOOT sound the J-79 makes on throttle up sure brings back memories. (F-4) Is it the nozzle restricting that causes that? What a great job you got!
jetracer 2 years ago
We industrial types are not really sure what makes that sound.
You aircraft guys all keep saying it's normal, so we have learned not to worry about it.
In our first test of a J79, we thought there was a problem...

Awesome vid!!Weren't they going to put a pair of J-79's in the Avro Arrow? When was the first J-79 made?I used to live down the street from Orenda in Malton.
dooalittledippsy 2 years ago
Actually, the first Arrow tests were
done with a pair of P&W J75s installed, because the Orenda Iroquois was not yet ready.
The J75 is a twin shaft turbojet that's larger and more powerful than the J79.
They are extremely rare now.
But the Iroquois was the most powerful turbojet of its era, and was only eclipsed by the later P&W J58, which was used in the SR-71 Blackbird.
If anyone knows where I can find a P&W J75 ( not J57), contact me. I want to buy it.

I want to get my own J-79 parts.
I want to build a J-79. Can you get one to run on LP?
Where do a get a spool, blades, stators, the case, and hardware? I'm ready to get into the task.
Great vid.
AugustusLarch 2 years ago
Sure, we have all of those parts. Better to get yourself a surplus or even scrap one, and refurbish it.
We got those , too.
You want a whole engine, or just some parts to start off with?
AgentJayZ 2 years ago
What's the ticket on the whole engine?
AugustusLarch 2 years ago
I really only want a downrated J-79. I don't have a use for a mach 2 powerplant. Do J-79's exist with a reduced spool. LIke 7 compressor stages instead of 17. I have already designed a machine for one J-79 but it is just transonic. I won't need a powerplant rated for 2x mach.
AugustusLarch 2 years ago
It just doesn't work that way.
If you want less power, you need an older, smaller angine.
Good news: they are less money.
For between 15-20K depending on condition, you should be able to find a J57 (10,000 lbs thrust), or even a J47 (about 5,000)...
Still, even at the lowest price levels, be prepared to throw around tens of thousands.
A decent flight-rated J79 will run over 100K. Less for engines in worse condition.
Keep in mind a new engine is in the millions!
AgentJayZ 2 years ago
I don't want a flight rated engine. I want a heap so I can counterfit the parts. The licence is up on the J-79. Anything goes. I don't want a J-47 or a J-57. I want a J-79 because it has higher production volume. I know that the J-79 was built in volume with a reduced a comp. spool. Theres a model for pumping natural gas that only has a four stage comp. There's also turbo shaft variants with a smaller spool. I have good facilities. If I have one set of parts, I can make more.
AugustusLarch 2 years ago
Don't take my word for it; ask around; ask everybody: the three "variations" of the J79 do not exist.
You are thinking of other machines, likely.
There are no reduced, or 4 stage compressor J79s.
There are no turboshaft J79s.
Check the GE website for historical engines. Ask everybody.
Good luck otherwise!
AgentJayZ 2 years ago
I found out about the variants from the Generel electric site. Where are you getting 'your' info? There are versions of the J-79 that run on a portion of the natural gas they are pumping inside the line. There are more variants than three. You seem to be hung up on the F-104 powerplant like it's the only version of J-79 that exists. Why?
I like the video.
AugustusLarch 2 years ago
OK, You got me there.
My info comes from building J79s and LM1500s, which are the ground power industrial version.
I have never heard of a reduced diameter J79, or a reduced compressor stage J79; those would be totally different engines.
All natural gas pipeline compressor station LM1500s are fuelled by the gas in the pipeline. It's just so convenient.
AgentJayZ 2 years ago
As for a turboshaft J79, The only thing I know of that comes close is an LM1500 coupled to its power turbine. This is a separate piece of equipment, and its output is a rotating shaft of approx. 17,000 Hp.
Just 'cause I've never seen 'em doesn't mean they don't exist. Put some pix up, OK?
AgentJayZ 2 years ago
My schedule is too busy for an extended recon mission for scrouge worthy hardware right now. I have been vlogging lately. Check out my channel. I am the epitome of speading myself too thin.
AugustusLarch 2 years ago
The J-79 is always the same diameter. I am reffering to the variants, or more properly the derivitives of the J-79. The thing that makes the J-79 and the derivitives special is the single spool and variable inlet stators. About every GE turbine powerplant has about the the same combustion and power turbine section. The turbofan and turboshaft units just have an added spool to this core.
I want to find a wrecked J-79 so I can copy the parts. I want to build one with a shortened spool.
AugustusLarch 2 years ago
The J79 shares no parts with any of the subsequent turbofan engines.
But... if you want to try - we have some wrecked J79s and a lot of parts.
We have a supply of spare parts, but we also have a pile (literally) of scrapped stuff.
I 've got a set of compressor cases and a compressor shaft all ready for you to chop up. Turbines, too.
Super cheap, because I want to see you succeed.

They made an exposed fan engine for Candair out of a short spool J-79.
The J- 79 is the traditional flagship of the GE aircraft powerplant line. The J-79 parts have been produced in many scales and appear in GE products today.
The parts are not interchangeable, only the form is the same. Every one of parts have a lot of engineering. They get everything out of them.
Hell yes I will haul away some J-79 parts.
My facilities are in upgrade right now. I have to wait. I will keep in touch.

Yes, it must be incredible to sit on top of one of these and open it up.
This test took place on a hot summer day, and it was impressive to feel the world shake. The video doesn't really reproduce even a hint of the fury and mayhem these things put out.
This engine is now flying in a Starfighter F-104.
The F-4 Phantom II had two of them.
The only aircraft I know of with 4 afterburning J79s was the Convair B-58 Hustler.
Footage of that one is rare, but out there.
