P-factor

[bomber64]

Does anyone know how to calculate a correctly close value ?
p_factor> 103 </p_factor

How to work it out even ?

And what should the effect be on these properties ?
m-prop-lbsft
n-prop-lbsft

I've changed category as I think this needs dev support.

If this is correct then with a +ve alpha the right side of the prop has greater 'bite' and there'll be a leftwards yaw.
This would be a moment on the n axis n-prop-lbsft.

With a +ve beta the top of the prop has a greater 'bite' and there'll be a downward pitch
This would be a moment on the m axis m-prop-lbsft.

The prop torque is added to the l axis l-prop-lbsft.

Looking at the forces on the prop
There is only a force of fbx-prop-lbs which matched the prop thrust value within the engine.
If we're saying p-factor is just a moving of the props centre of pressure outwards from the hub then I see no issue with this.

So the issue I have is that with +ve angle of attack (zero beta) there's far too much m-prop-lbsft and not enough (maybe) n-prop-lbsft.
And correspondingly the same with beta.
