Performance Characteristics of Vehicles Travelling in Near-Earth Orbits at Supersatellite Velocities,

Abstract : The performance of several types of vehicles which have the capability of traversing near-earth circular orbits at supersatellite velocities was investigated. These vehicles use a normal thrust component or negative lift to maintain the circular orbits. Four basic types of vehicles were considered: (a) constant thrust rocket, (b) perpendicular, modulating thrust rocket, (c) inverted glider, and (d) inverted cruise vehicle. Although no particular missions for such flights were envisaged, it is conceivable that supersatellite vehicles (SSV) could be used for reconnaissance, orbital rescue missions, or delivery of high priority payloads in both military and non-military contexts. Specific impulse values of 300 and 600 seconds were studied for all powered stages. (Author Modified Abstract)
