| 摘 要： | 1引言MPT属于电热型电推进,基本原理是利用微波发生器将来自电源系统的电能转化为电磁能,然后电磁波在谐振腔中产生谐振并与工质(可选用N2,H2,He,Ar,NH3,N2O或水蒸气等)耦合,使工质离解、电离,形成等离子体,最后高温高压等离子体从喷管高速喷出而产生推力。MPT的最大优点是没有

| Abstract: | Microwave plasma thruster(MPT) is one type of electrothermal propulsion devices.Its characteristics including high specific impulse,long lifetime and slight plume contamination make it very attractive for future application.Making use of the vacuum experimental system,the factors which influence on reliable startup and steady work of 100W MPT such as different propellants,position of inner-conductor,sealed materials of microwave tie-in,probe length,mass flowrate and input power were analyzed and observed.The relations of performance parameters such as thrust,specific impulse and efficiency among mass flowrate of propellant and input power of microwave were discussed and drawn. |
