C17 - amazing short landing and "fire" reverse

[dirkhh22]

Does the pilot have a mirror :P ?

[RolfTrondheim]

Say...was it a 'bird-strike' on reverse?

( the little poff / fire at right wing, after the C17 start it's reverse-taxing)

[garygalea]

I think the fire came from using a reverse-thrust at low speed. In commercial aircraft, this is limited to a certain speed after landing, let's say, 70 knots, then, the engine must be "idled" after that point.

The probable cause of that fire is that the same hot gases that were rejected by the engine were being sucked again by the same engine. That means, if gases were rejected at about 600 degrees Celsius they were being heated up again. Causing the engine to heat to high temperatures.

fake

[Noobular4]

its not fake. When a jet needs to land quickly they use reverse thrust as well as brakes and spoilers. The reverse thrust is usually only used to slow down the jet a short while after touchdown. In this case it was used instantly.

@humanbeer You are in idiot.. this is Compressor stall.. learn some thing before you say so kid.

[zachdecou]

You can see arcs of static electricity between the nose and the runway just before the compressor stall, and between the belly and the runway shortly after. Really interesting!

[DarryllK]

@zachdecou They're strong vortexes which are caused by heavy thrusting at low speeds. The engine is trying to suck too much air for how slow it's going and the air simply can't keep up causing the compressor to stall.

[dwodno]

Does this thing have driver and passenger side rear view mirrors or does the crew chief hop out and direct them by radio?

[SoccerBoy77]

it seems that compressor stalls happen quite often during this demo.

[JonnyCrash]

Yeah. I've seen a compressor stall in person. Kinda cool, but it freaks out the jet troops.

The only cargo planes that can do these manouvres...the last masterpiece of the genial sicilian ingeneer Gabrielli, "author" of the Fiat G. 55, considered by German Luftwaffe "best Axis fighter", in 1943...

[thewolfpath]

Sorry I made confusion with the c 27 j spartan....

[102trafalgar]

Really fantastic, thanks. The "fire" was a compreesor stall caused by exaust gas being drawn into the intake while reversing. It usually seems to happen on no. 4 engine?
