The present invention relates to a field emission thruster prewetting device, which comprises: an emitter unit in which metal used as a propellant for satellites is prewetted; a storage unit for storing metal used as a propellant; a heater unit which heats and liquefies the metal used as a propellant stored in the storage unit; and a piston unit which travels back and forth inside the storage unit and supplies metal liquefied by the heater unit to the emitter unit. After the metal stored in the storage unit is liquefied by the heater unit, the liquid metal can be supplied to the emitter unit by moving the piston unit to prewet the emitter unit.

    본 발명은 전계방출 추력기 프리웨팅장치에 관한 것으로, 인공위성의 추진제로 사용되는 금속이 프리웨팅되는 에미터유닛, 추진제로 사용되는 금속을 저장하는 저장유닛, 상기 저장유닛에 저장된 추진제로 사용되는 금속을 가열하여 액화시키는 히터유닛, 및 상기 저장유닛 내부를 왕복하며 상기 히터유닛에 의해 액화된 금속을 상기 에미터유닛에 공급하는 피스톤유닛을 포함하며, 상기 저장유닛에 저장된 금속을 상기 히터유닛에 의해 액화시킨 후 액체 금속을 상기 피스톤유닛의 이동으로 상기 에미터유닛에 공급하여 상기 에미터유닛을 프리웨팅할 수 있다.
