Hurricane engine torque

[Peril]

What you may be looking for is evidence that the wing, engine mount or rudder has been shaped with this 'counter' torque rotation in mind.

I fly and build RC planes too


I'll see what I can find in my data set on the Hurricane.

----------------------------------------------------------------------------------------

The Vstab of the Hurricane was offset 1.5 deg to the left. That offset should provide some point where the plane rolls to the right. Does it yaw right with throttle off in CoD? If not, why not??

Logical progression here, this offset was intended to counter some of the torque, most likely neutral for cruise speeds?

----------------------------------------------------------------------------------------

See below the tested speeds at which the plane was neutral in trim, under climb power (most torque effect) and at the glide (least effect).

It appears at around 130mph the plane was neutral in 'roll' but did still have a slight side slip. Note here the key is neutral in roll, ie. no aileron input needed to maintain bank angle. Side slip generated in the glide was undoubtedly due to the 1.5deg fixed vstab, thus evidence of this functioning as an intended counter to torque whilst under power. Furthermore at climb speeds above 130mph it was necessary to apply left aileron likely because of the 1.5deg vstab incidence influence was greater than that of the torque under power.

Hope this helps someone make a more accurate sim.
