Abstract
Though speed of the modern supersonic airplane in the pneumatic layout with delta-wing and big sweepback etc. characteristics was increased, the problems were contemporary appearance in high altitude and velocity which aero lat-eral movtion damp and yaw/roll lateral static stability would get smaller and the roll versus swing ratio would get bigger. In order to improve aero lateral fly stability in high altitude and velocity, basis on coupling relation of the aero roll and yaw two channels, the high speed aero Lateral Stability Augmentation System (LSAS) were designed that roll rudder departure angle signal was imported to the yaw channel, so that yaw angle speed feedback signal was got enhanced and aero turn ma-neuverability was got improved. A great deal of contrastive simulation was done under the Matlab platform. The simulation result showed that the aero lateral LSAS structure was simple and reasonable, and easy to realization. At it control law ratio was chosed reasonable, the designed aero LSAS can improve aero fly quality.关键词
