KungFuCharlie Posted July 24, 2010 Posted July 24, 2010 Canadian f-18 crash today here is the link for the video http://www.globalnews.ca/world/crashes+alta+airport/3315220/story.html looks like the 89 mig crash; but lower? engine failure or stall? I don't think it was an engine failure. You can hear the engines going to MIL and it looks like both vents were tight indicating MIL. In AB or OFF they would open up wide. Looks like he was at half flaps and started to yaw beyond recovery. Hard to say. It was good to see the pilot get out safely though. That is the important part. But it is too bad the forward fuselage didn't make it... would have made a great simpit for my garage. :D
IvanK Posted July 24, 2010 Posted July 24, 2010 (edited) Geez all those Rivets to hold the helmet liner in .... good British engineering. As to the F18 prang. My thoughts Slow speed High Alpha pass, possible loss of thrust in one engine then Vmca departure. Most F18A airshow High alpha pases are flown at no more than 25Alpha so as to limit the potential of a Vmca departure with thrust loss in one engine. Though looking at the video it does seem this is a 25Alpha pass compared to other similar videos. Flaps would be in Auto in this manoeuver. Edited July 24, 2010 by IvanK

mvsgas Posted July 24, 2010 Posted July 24, 2010 It look like he was having problems the moment he started the maneuver. You can see the aircraft Yaw to the right at least twice before losing control. I do not think it was a stall since you can not hear a popping sound nor do you see flames shoot out. To whom it may concern, I am an idiot, unfortunately for the world, I have a internet connection and a fondness for beer....apologies for that. Thank you for you patience. Many people don't want the truth, they want constant reassurance that whatever misconception/fallacies they believe in are true..
mvsgas Posted July 24, 2010 Posted July 24, 2010 (edited) I guess it could be a stall after all. Maybe Domestic Object Damage (DOD) or maybe bird strike?

KungFuCharlie Posted July 24, 2010 Posted July 24, 2010 Looked like both engines are at MIL to me but the video isn't all that great. The LEX do look slightly down and you can see a bit of the left flap at one point so I still think he was at half flaps. But again, video isn't all that great so there is a high possibility I am wrong. :) I don't think it was a bird strike... that would have generated a lot more visual and audio indications.

IvanK Posted July 24, 2010 Posted July 24, 2010 (edited) Yes 1 Nozzle open 1 closed = asymmetric. The eyewitness speaks of classic Engine stall symptoms Pop...Pop and sparks. Also in the video just before the yaw starts the Airshow music is drowned out by increasing jet noise. I suggest this is the pilot applying thrust on the good engine to compensate for loss in the bad engine .. the yaw that follows is classic Vmca departure.... i.e. insufficient yaw control available at the slow speed to handle the Thrust assymetry. Edited July 24, 2010 by IvanK
Antartis Posted July 24, 2010 Posted July 24, 2010 I think engine compesson stall from high AOA and assymmetric thrust.

59th_Buncsi Posted July 24, 2010 Posted July 24, 2010 Its maneuvered. To make reach the vertical position, thats more safely to open the chute. Tek, this eject is like Kvochur's eject in 89 Le Bourget :) [sIGPIC][/sIGPIC]

mvsgas Posted July 24, 2010 Posted July 24, 2010 From the original video posted it was too rough to tell. From the latest videos, photos, and eye witness reports that came out it is pretty clear. When I saw the video, you can see the pilot trying to correct the yaw of the aircraft twice. I think the moment he started the maneuver the engine might have had problems already but may have not given any indication to the pilot. Then I think the pilot set the engine to AB ( hence open nozzle on the left side) He set AB to try to accelerate the aircraft out of trouble, but with the aircraft at slow speed couldn't correct the asymmetric thrust.

Griffin Posted July 25, 2010 Posted July 25, 2010 New video by kuslin2:thumbup: The second video is the footage of an incident when a Su-25 was hit into the cockpit by a rifle caliber bullet. They were flying around 1000 m when the lucky bullet found it's target. The hole in the canopy and the found bullet are shown in the end after 9:25 minutes. Around 5:30 you can hear the pilot starting to get nervous and raising his voice because the pieces of canopy hit him in the eyes. He actually shouts "I can't see anything!". Other pilots talk him through it and tell him to RTB.

Bwaze Posted July 25, 2010 Posted July 25, 2010 Wow, look at the Airbus A380 footage - in IR it looks like he is chrome plated, but camera shows that it's painted with normal white colour. And F-22 has quite large IR signature. Interesting video.
