Unexpected Behaviour

[Vitesse2l]

Hi all,

 

I'm wondering if anyone else has seen this...

 

I ran the cold start instant action mission and on a whim decided to navigate to Kutaisi. It's been a while since I've flown the P51 and of course i forgot something - after a while the engine seized. I'd left carb heat on and flew at 22000 feet.

 

I thought then I'd glide to a wheels up landing but the Mustang didn't settle into a straight, wing level descent. I found it was yawing alternately left and right. The turn and bank instrument was going like a metronome and stayed like that until I got much lower and the glide settled as I'd expected.

 

The rudder wasn't moving (unless I made inputs) and I tried the starter, which gave the expected lump of torque and turned the prop very slowly.

 

Anyway, I don't have the track but wondered if it had happened to anyone else, and maybe why!

 

Thanks!

I've just tried again.

 

For some reason blowing the engine took much longer and I was so cruel with the throttle.

 

I got the yawing again, though. This time I think it's initially a reaction to losing engine power and if I didn't touch the controls it would slowly settle out, but set off again if I banked.

 

I'm don't know if it's right or wrong, just interested in what's happening.

 

I'm running the latest beta, if anyone is interested in trying this out.

Some months later I posted the explanation of this effect. In few words it an effect of stopped prop working as a wings - any yaw causes pitch moment and any AoA changing causes yaw moment changing. This is the effect of prop blades AoA changing.

Thank you Yoyo.

 

I will look for your post.

 

Cheers!
