• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

FSX Torque equation in heli

Hi all. Does anyone of you have an equation that could describe torque in default Bell206?

I found that Bell has a torque effect and depends by "main rotor drag" and "main rotor friction/solidity" values. Modifing accordingly them the heli starts to yaw to left or right by collective inputs.

I just need a general equation to link power, blade drag and solidity-friction(?)

This Torque Effect is Normal in all Helicopters , and is Counter acted with the Rudder Pedals - Johnman
 
Yes I know. I'm just wondering how main rotor drag and friction factors act in Fsx model.

When main rotor drag coeff is >0.013 helicopter starts to yaw to left. This may be important to developpers that wants model clockwise rotor helicopters (Russian and European models). But main rotor friction value also play a role in this. The two coefficients interplay in concert. If main rotor drag is <0.010, the yaw is on the right (default is 0.009). It's weird... so this is why I posted my question.
