16. Plasma Problems in Electrical Propulsion

摘要: Publisher Summary This chapter discusses the plasma problems in electrical propulsion. The involvement of physics and technology area space propulsion has occurred because (1) with exception nuclear explosions, or electromagnetic acceleration conducting matter is only feasible way bringing rocket exhausts to very high velocities necessary for deep flight payloads men their support equipment; (2) Ionized gas, plasma, most convenient material use, as by virtue its usually low density, it can be brought requisite without expenditure prohibitive increments energy. Several excellent developments rationale are available. field electric concerned medium heavy elements, fairly well ionized, having electron ion densities range 10 11 -10 15 /cm 3 .
