Autorotating rotors can, in a single configuration system, provide the capability for retardation, stabilization, drag force modulation, glide at useful L/D ratios, maneuvering and control during descent, and low-velocity touchdown. A given configuration will deploy over a wide range of speeds and dynamic pressures. These features have been confirmed in flight tests of remotely controlled systems. A rotor system was successfully deployed and operated in windtunnel tests at speeds up to Mach 3.0. Preliminary design studies for a manned capsule system, using present state-of-the-art techniques, indicate that installed weight compares favorably with other maneuverable gliding recovery systems. If deployed at 100,000 ft, the rotor will provide approximately a 25-mile glide range. An important attribute of rotors is the potential for making safe emergency landings in unprepared sites. Flexible blade concepts and power augmentation may enhance future applicability of rotor recovery systems.
