RESUMO

The design of static and integral algorithms for a fly-by-wire controllability and stability augmentation loop for a single-rotor helicopter with a tail rotor in hovering flight mode is considered. Methods for the cross-coupling choice to provide decoupling of yaw and roll motions as well as vertical and yaw motions are developed. It is shown that the proposed integral algorithms provide ideal helicopter controllability characteristics and may be considered as the basis for flight envelope protection systems; in particular, for vertical and side velocity limiters as well as yaw limiters.
