Westland Whirlwind

Secondly regarding the twin engines, I only have a single throttle and have most always flown single-engined planes so I just don't know, but is it possible to turn one engine off at a time with Aces High or to have say one engine at half power and the other on full power with WEP for example?

Yes, you can select an engine and the throttle, and other engine commands, will only affect that engine.  Default is having all engines selected at once though.

Oops.

Lovely bird, I saw it and right away thought what's that 262 doing with props and a bullseye on the side?

Thank you Karnak. So given two separate throttles you can work each engine completely separately, engine off and on and WEP and so on simultaneously?

Correct.  It is one of the things that makes me want the new Thrustmaster stick and throttle so much.

Thanks Karnak

+1 To any new early/mid war plane. What's with the 262 and the props? Love the warbird though.

I'm still very curious if anyone can explain the net resultant torque effect question. I'm trying to read up but it quickly degenerates into Mathematics, which is a language I have trouble with

+1 for the whirlwind and for anyone who hasnt seen this yet.

I love it even more.

I found this picture on the website of the R.A.F. Museum:-



You can see the open radiator flaps and get an idea of how small it was for a twin-engined fighter when you see the men standing next to it. You can also just see the rear view mirror at the top of the canopy.

That would great alongside Mossies and Lancs on town attack duties

Less than 50 Ta152s were built.

57 with two 152cs so 59 total.

a tendency to yaw under full power (during take-off and climbing) would be about it I imagine, just like a single engine fighter. P-factor means the thrust lines are offset from the prop axes slightly:

[nrshida]

Aha! So suddenly the light bulb begins to glow (dimly). So P-Factor is very similar to the effect that limits the top speed of helicopters, that the advancing blade produces more lift than the receding blade. In this case the down stroking side of the rotating propeller?

So even with same direction props the effects are dampened by the thrust spacing from the centreline which with the Whirlwind is also the C of G? Won't this spacing from the centreline affect hard turns and manoeuvres like Wingovers also?

Basically there seems there isn't a huge advantage then to contra-rotating propellers? Apparently not enough to encourage the designers to hand one of the Peregrine engines, which was easily done apparently.  

Thank you RTHolmes, that drawing helped a lot!
