APPLICATION OF AERODYNAMIC LIFT IN ACCOMPLISHING ORBITAL PLANE CHANGE
Abstract
This study considers the concept of a hypersonic glider-type spacecraft utilizing its aerodynamic maneuvering capability in performing orbital plane change. For lifting vehicles an optimization procedure is developed which defines the proper vehicle attitude, propulsion utilization and sequence of operations to produce the maximum plane change for a given fuel expenditure. The results obtained are compared with the fuel requirements for a pure propulsion (nonlifting) plane change while remaining in orbit. Specifically, the optimum bank angle, angle of attack, entry angle, thrust alignment and thrusting procedures are defined. In addition, the advantages of high L/D vehicles are graphically illustrated. The method is seen to be more efficient than the pure propulsion method, but is found to be far more complex and requires longer times to execute.
