Supermaneuverability has been proposed as a revolutionary concept which will lead to quantum improvements in fighter aircraft maneuverability. The term supermaneuverability has been used to mean increasing the maximum usable lift, dynamic lift obershoot, and post stall maneuverability. Post stall maneuverability is thought to significantly improve maneuverability; however, it is a very high risk concept. Post stall maneuverability will require the maturation of many different areas of technology. Innovative aerodynamic technology will be essential. Positive control authority will be required in all three axes throughout the flight envelope of the aircraft. Post stall maneuverability will require a very high thrust to weight ratio of the aircraft coupled with thrust vectoring. A fire control system and air-to-air weapons must be developed which are compatible with the flight envelope of the aircraft. Finally, new air combat tactics will have to be developed to take full advantage of post stall maneuverability. Research to investigate the fundamentals of high angle of attack aerodynamics of fighter aircraft should continue. Emphasis should be placed on developing configurations which eliminate high angle of attack instabilities. The influence of high pitch rates on the lift and drag of an aircraft should be considered in detail. New experimental facilities and testing techniques will have to be developed. State of the art numerical methods should be used to establish a fundamental understanding of the flow field while more powerful numerical techniques are being developed. The potential payoffs of post stall maneuverability should be demonstrated through simulation before initiating a large scale research program.
