P&W-F100-220C Engine Stall

Here is a video I took while running ground on an engine run at the Elmendorf AFB testcell in Alaska

[@jetmack32]

Funny, as I remember it we were doing an aug fuel analysis (yes I'm the one running the engine) the ones recording were observers. For those that don't know that was neither a stagnation or a insipid stall, it was an augmenter instability due to lack of fuel being supplied to the spray rings. The engine cleared the excess pressure in the compressor as you can observe after the augmenter blowout by the exhaust nozzle movements. P&W F100-220's are known for this we were just troubleshooting the problem.

Robert Anderson spray rings? The reheat fuel nozzles.

[@harralrobinson1067]

I agree, engine recovered, no stagnation, on the -100,we would almost call it a hard lite, Aug fuel pressures were at times the hardest to troubleshoot. I ran that hush house along with gene hoffner, Bart Stanton, Ron Rodgers, Greg Vaught, and a good crew, 81 to 86, 88 to 90, great time. F15 b, c, e. Best job I ever had

[@MilitaryMatters1]

Oooh, so you guys were the ones keeping our birds in the air, ah? MY MAN!

[@UsafRich08]

Wow.... Elmo has some of the best facilities in the Air Force. Especially with the high qualities engines they have

[@amnfoliver]

I worked there and probably worked that engine. I left there 31 Oct 2007. I miss that job, well on to bigger and better things.

[@repairdroid77]

Good video, thanks for posting it.

[@Kikesurf1]

Pratt and whitney the model is the name of the video, F100-220C, I think this engine is used in an F-15, i might be wrong though

[@y2kcobrar]

@foxcummins Engine would not be going back into an aircraft until the problem was identified and fixed. That's half the reason for doing run like this. But I do agree with you, sounds like they knew it was having problems and induced one to get it on video.

[@7249xxl]

0:31 YES SIR! red alert 2 alied engineer is that you??

[@edelange08]

If you leave the PT6 line disco'd, it'll do that every time you head toward min aug.

[@UsafRich08]

Oh give me a break. Sometimes you have to duplicate problems. It is not a matter of wanting to do it. Crazy things happen with Pratt and Shitney's. When a stall occurs the engine is not receiving enough air flow into the engine. IT COULD be anything from the controlling of the full system, to the actual actuators on the motor. These guys don't just play around at test cell, they get the engine ready to be installed on an aircraft

[@UsafRich08]

No one says unrecoverable stall.... Its a stagnation. I work 229's, these motors are gravy compared to both -100's and 229's.

[@hawkplaya94]

that happens to my lawnmower all the time

[@WILLZE]

Nice

[@porousorificePilot]

Front view of pac man eating a jet engine!

[@jumpingjeffflash9946]

Worked P&W on the F-16 in the USAF, soooo many issues. GE motors were so much better.

[@goddamnbouy]

@nocalsteve no they pulled back from an already advance PLA and then advanced it rapidly, something is choking the airflow. this should not have happen if everything was rigged right. the fact that they were filming shows that they had done it before and wanted to do it again on film.... potently causing internal damage.

[@katherineberger6329]

I'd surmised that they'd probably seen it happen in that engine previously and wanted to get it on video for examination/troubleshooting purposes.

[@nocalsteve]

So that's how they keep the bat cave warm during the winter.

[@UsafRich08]

The actuators that move the stator blades inside the engine

[@mushmouth1981]

Correction, technically a recoverable (which no one calls it) is a stagnation. That's all run clas crap. Regardless, recoverable or non, the -6 or the 70FI doesn't realy give a crap, a stall is a stall. LOL

[@x0lamborghini0x]

Yesssss SIR! LOL

[@cfb36]

awsome thats what i want to do when i join the air force

[@die2end]

Yeah!!! What he said

[@coydog7902]

JDM LIFE!!!!!!!!

[@derekwall200]

was that a compressor stall?

[@rine303]

Good toys

[@nocalsteve]

That doesn't look like an engine stall to me. It looks like the operator intentionally shut the engine down and didn't restart until after letting fuel blow into the tailpipe.

[@y2kcobrar]

@JetMechMA Why would you think that? What about Alaska makes you think they can't maintain their own engines?

[@yamahonkawazuki]

@y2kcobrar maybe fuel starvation?

[@nichkill123]

Chuck norris FAN

[@sirstar45]

O.o thats a nice little engine for my rc car! how much? oh... 1 million $ rlly? :/

[@FlightSimx97]

@n328kf yea that wuz that is wut it should look like

[@Kikesurf1]

or GE...

[@basimpsn]

Okk so that's what happen on the other video label (CATASTROPHIC JET ENGINE FAILURE) LOL

[@mushmouth1981]

Freaking Pratt's. Hahaha

[@LaurentLaborde]

me too ^^

[@crossfirebass]

I don't think this test was run properly at all!!! I didn't see anyone throwing frogs into the intake LOL!!!

[@spenceronni7]

HAHAHAHA. That was at Kunsan, wasn’t it?

[@weimorts12345]

lol how funny wold it be if a guy walked out of the tunl all black lol

[@armyboy0579]

Bird Strike?

[@RandomShit169]

What drugs are you on?

[@goddamnbouy]

I'm an Aerospace Propulsion Craftsman... And stalling it over and over is how a Core gets fucked up.

[@foxcummins]

good way to trash a turbine engine, force a compressor stall. hope the pilot of the plane this went back into knew about this!

[@BTI353]

You must be a control stick actuator. We dont need your input in maintenance matters, we dont tell you how to fly (well unless you over G).

[@ovie202]

Hello! I am reaching out to see if ABC can have permission to use your video for all partners and platforms. Thanks!

[@snowball787]

ha ha it farted

[@seanwhite7532]

Come on.... FADEC... he can't advance the fuel too fast

[@mejne]

@foxcummins this is called engine testing dummy

[@427SuperSnake1]

He put in power too fast..

[@spenceronni7]

The fuel control increases and decreases fuel flow at the correct rate regardless of operator input PLA.

[@fokjohnpainkiller]

>FADEC >hE pUt fUEl 2 fASt This isn't your grandfather's carburettor

[@technicalscience]

Cool video, but a little too GOD BLESS 'MURICA for me.
