Similar Problem?

Re my comment, I realise that left aileron is being applied, it's just the ailerons don't appear to move much it seems... Probably typical for a high speed aircraft.
|
Top screen shot - is that RIGHT rudder input (note the position of the balance horn)? |
At the very start of his take-off roll, it looks like the left flap is down but right isn't. Or is the right just lost in the shadows?
|
What looks like to be the left flap down is actually the left radiator, as the aircraft moves past you can see it move into perspective.
|
The evidence presented in the two photos show right rudder and left aileron being applied.The ailerons would not have been very effective due to the low speed. This leads to auto rotation, where applying left aileron causes a roll to the right. This was the method used to spin DHC1 Chipmunks. The photos show that it was past recovering and the pilot did the right thing in closing the throttle.
|
Yeah makes all the training to keep one's hand on the throttle during takeoff come into perspective. A half second delay in the chop might have meant the chop for some poor folks on the sideline.
|
I think the left aileron would have been a lot more effective if the right rudder had not been applied! I doubt the pilot was aware of what was happening with the rudder in the brief moment he had to try and comprehend why it wasn't responding to left control column input.
|
I cant make it out from the video but could it be that being an auto conversion with a PSRU the prop turns the opposite direction to a lycoming/continential. I wonder how familiar the pilot was with the aircraft.
Or a control lock still in place? Or just low performance pilot in high performance aircraft? |
Not that I'm any expert with Spitfires (far from it!) but every time I've seen them take off, they accelerate to level attitude ie tail wheel well off the ground and then lift off. Looks like he let it get off the ground too early, too slow, tail wheel still on the ground hence high nose attitude and lost it. Did well to recognise a bad situation and pull the pin before it got a whole lot worse.
|
tip stall.. research it. especially with elliptical wings.
|
crash
The left wing shows more lift at lift off, I would agree with asymmetric flap problem.
|
The only observation I can make is that he didn't (couldn't ?) get the tail up to reach proper Vr.
|
Misapplication of all that Merlin power, obviously...
|
It's blurry, and you only get a brief look.
Take a look at the video Pseudonym posted on Page one. You have a 1 second window to look at the back view, almost square on before the video goes blurry again. Revising my thoughts on the initial video....not quite convinced, but all the same. |
jas24zzk I'm intrigued as to what you see in that section of the video - I've had another look and the flap (s) may be drooping slightly in the rear view - frankly though, I suspect my own flaps and a few other bits would be drooping a little after a bang like that :eek:, so I'm not sure you can read too much into it.
|
It appears the the roll commences just before lift off, with the left wheel leaving the runway first & the roll continuing through out the accident sequence.
|
Was there a cross wind?
|
I know nothing about this aircraft. Is it a real Spitfire or some sort of pretend Spitfire?
If real or close to, is torque roll likely to be an issue? The right wing going down suggests the possibility. Dr :8 |
One of the 80% scale, home brewed ones. Not sure about this one, but the normal powerplant is an Isuzu V6 allegedly good for a bit over 300 gee gees. Not too bad for 800kg odd, but well short of Messrs Rolls and Royce's effort.
