Damping derivatives

Derivatives of the six aerodynamic coefficients with respect to the normalized rotation rates. The roll, pitch and yaw rates p, q and r [rad/s] are rotations about the x-, y- and z-direction of the CPACS coordinate system through the moment reference point of the model, positive by the right-hand rule. They are normalized with the reference length l and the free-stream velocity, e.g. p* = p l / V_∞ for the roll rate. Each derivative is a vector with one value per point of the aerodynamic map, i.e. of the same length as its parameter vectors. The coefficients themselves are given in the aerodynamic coordinate system (section 4.2 of cpacsType).
