Abstract : A design objective of high Mach number performance manned flight vehicles is concerned with flight operations such that minimum longitudinal trim drag is achieved. The utilization of longitudinal statically unstable vehicles is one means of obtaining this desired objective. Taking a delta wing canard controlled aircraft as an example, this Report presents a control concept based on three redundant systems of compensating for static instability. These systems consist of a mechanical stability augmentation system, a conventional autopilot system, and a fuel transfer system. Each system by itself is capable of permitting adequate control of the aircraft, so that loss of any one system still permits a high degree of flight safety and reliability. (Author)
