DYNAMIC STALL CONTROL FOR ADVANCED ROTORCRAFT APPLICATION

Advanced concepts designed to improve the lift, drag, and pitching mom ent characteristics of rotor blades have been investigated for the pur pose of enhancing rotor maneuver capability. The advantages and disadv antages of these concepts have been evaluated using both computational and experimental means. The concepts that mere considered in this stu dy included a leading-edge slat, a deformable leading-edge, and upper- surface blowing. The results show the potential of these concepts for substantially improving the performance of a rotor.
