Abstract : The objectives of this ONR sponsored investigation have been to design a variable camber system, establish its performance capabilities and provide data to support a decision for flight demonstration. The variable camber wing consists of leading and trailing edge flaps that can be deflected to match the camber requirements of any flight condition. Wing leading and trailing edge flaps with flexible skins, combined with a simple internal mechanism, are used to achieve smoothly curved upper surfaces so that an optimum wing shape can be provided throughout the flight spectrum. The variable camber system combines the resulting improved aerodynamic characteristics with an automatic flight control system that deploys the flaps in response to airplane flight requirements without adding to pilot workload. This system achieves outstanding transonic combat, subsonic cruise and low speed performance without degrading supersonic performance capability. (Author)
