New to FT- Change Pitch Angle with Respect to Speed?

4,081 CMS1288  3 months ago

Hello, I’m working on a stealth aircraft with canards and V-type rear stabilizers, all on rotators.

I want to keep maneuverability at low speeds and limit g-forces at high speeds. Can you guide me to an expression that changes the angle range with respect to IAS?

I had some success with the Boolean a?b:c expression, but the change is obviously sudden. I’d like a smooth transition as speed increases.

Thanks in advance!

    Don't choose between many constants, see if you can fit a curve or line through your experimental values
    For straight lines, try this

    You can use a?b:c for it and it still can be a smooth transition. You just have to do it multiple times with multiple speed. For example
    IAS > 100 ? 30 : (IAS > 200 ? 25 : (IAS > 300 ? 20 : 25))
    something like that.
    I am not an expert in funky trees either and i am sure there is a better way to do this.
