Abstract : Cross coupling between the yaw axis and other control inputs of a V/STOL aircraft limit its performance capabilities. Yaw control augmentation was investigated as a means to reduce the cross coupling affects. Using the CH-3 helicopter as an example of V/STOL aircraft, this report defines yaw damping, turn coordination and heading hold control laws that can be used for yaw control augmentation. Improved vehicle performance is achieved by using the recommended control laws in a yaw control system. (Author)
