Applicability of Electric Propulsion for Future Military Satellites

Abstract : The feasibility of using electric propulsion subsystems to perform conventional propulsion functions in mission areas of Air Force interest is investigated. Consideration is given to using electric propulsion either alone or in conjunction with conventional propulsion subsystems. In each case, the results are compared with the conventional propulsion subsystem that otherwise would be used. The analysis identifies some areas wherein the application of electric propulsion would result in substantial cost savings, but the study also indicates other areas in which the applications of electric propulsion is not cost effective for the missions under consideration in this study.
