Computer Programs for Helicopter Aerodynamic Stability Evaluation
Abstract
The three equations of motion for helicopters are reviewed for both pitch and roll. These include provisions for a simplified second order stability augmentation system. Two methods of calculating the required stability derivatives and solution of the equations of motion in terms of period and time to damp or time histories for various control motions are shown.
