DWheel:

Path: SC/Attitude

% Computes the damping coefficient ratio for a damper wheel.
 Assumes a symmetric spinning spacecraft with a damper wheel about
 one of its transverse axes. The damping is assumed to have 
 minimal effect on the spin rate. This function is useful for
 studying the behavior of rigid bodies with damping and for
 setting the damper wheel parameters when a damper wheel is used
 to model damping from other sources such as slosh or magnetic
 eddy currents. The damped natural frequency is constrained to be equal
 to the undamped nutation frequency.
