Body axis vs stability axis
WebDec 7, 2014 · Constant Friction Vs. Variable Friction. All knee systems require some degree of swing control to maintain a consistent gait. In many cases, this control is provided by mechanical friction at the axis of rotation and is adjusted to match the normal cadence of the opposite leg. Constant-friction knee units are simple, lightweight and dependable.

The Direction Cosine Matrix Body to Wind block converts angle of attack and sideslip angles into a 3-by-3 direction cosine matrix (DCM). This direction cosine matrix is helpful for vector body axes to wind axes coordinate transformations.
