Stunt plane loses wing!

[GoldenRivet]

and no...

its not that stupid CGI one either!



this man's BRS paid for itself in full!

[TLAM Strike]

In Soviet Russia airplane hits the silk...

lucky guy if he only burned his feet!

what is it the black thing with the red fabric that flies from the plane shortly before the parachute launches? (around 17 secs) Is it the roof of the plane or the initial parachute?

[gimpy117]

i would be a drouge chute to pull out the main

it would be a small rocket, which pulls out a drogue chute which pulls out the main canopy

Its the 'drouge chute' of sorts. It appears to be a projectile with a sleeve that is 'shot' out and pulls the main chute out of its storage. The main chute is packed into the sleeve and only fills once the sleeve is slipped off.

By the way.. yea thats about exactly how I would expect a plane to react after shearing off a wing.

What gets me is it was not exactly under heavy stress when it failed. Negative stress yest but not like he was 'yanking it'.

[AVGWarhawk]

The chute sure did put the plane down gently!

[GoldenRivet]

well though he may have been under a relatively low load... i think back to the wing spar problems they had with the T6 a few years back which required inspection / replacement.

years of aerobatics and high G maneuvering could cause catastrophic structural failure during relatively low stress maneuvers.

think of a paper clip... bend it until it is straight. Now "overstress" it by bending it in half.

notice it doesnt break?

now do it again.

same result.

do it 20 more times

on that 21st bend, before you even get it bent very far... SNAP

same concept

Thanks for the answer(s), guys! Learned a new word today: drouge chute (english) = intitial chute (pengunish)

I have seen footage from WW2 gun cams, where the plane has exactly the same behaviour after a wing is shut down.

[GoldenRivet]

when an airplane loses a wing, all of the lift is now developed solely on one side. thus it will generally roll uncontrollably toward the missing wing. just as we see in the video.




that is why is BS... the plane does the exact opposite of what physics demands that it should do.

From the video's description:

The pilot was strapped into his seat when he pulled his parachute

Nasty little detail, thank god the video proves otherwise.

You would think that this would be looked for under very close scrutiny just due to the nature of the planes service life.

But then again stuff happens.

[GoldenRivet]

Im sure it is something they inspect.

they have methods of detecting hairline fractures in the metal - though im sure it is very expensive.

but even the best inspection can miss something.

[Tchocky]

Couple of ways to find those cracks - magnetic field measurement, X-ray, boroscope. But yes, very expensive and rare, I imagine, for small private aircraft.

Looks like an Extra 300?

The video is obviously mistaken.

If the pilot pulled his chute while strapped in the chute would have had nowhere to go. no air to catch it. and would have been too small to adequately slow the decent of the aircraft.
