[Question] [Enhancement] Aerodynamics #163

Open AlessandroZavoli opened 2 years ago

AlessandroZavoli commented 2 years ago

Is it possible to add custom aerodynamics to an object, e.g., to model wing-based objects like airplanes or helicopters?

Do you mean something like lift&drag plugin in gazebo?

AlessandroZavoli commented 2 years ago

Yes, something like that. I could provide the mathematical equations for a few cases of interest (e.g., flat plate with no lift, 2D airfoil) or a generic model in terms of classical aerodynamic coefficients.

This is probably lower in priority than issue #156, that is, fixing second-order terms in the Euler equations for attitude dynamics.
