本发明公开了一种射流推进装置及其测试系统。所述射流推进装置包括腔体和位于腔体内且可在腔体内往复移动的活塞,腔体包括外壳和设置于外壳内壁的多个环形线圈,活塞包括内部中空的活塞本体和设置于活塞本体外壁上的多个环形磁钢,环形磁钢与活塞本体一体设置,且环形磁钢和环形线圈配合形成交流永磁同步直线电机。本发明采用交流永磁同步电机直接驱动活塞的方式运行,驱动电流小、电机峰值推力可达数百牛,传动效率高、射流速度快,且驱动部件与活塞一体化设计,结构紧凑。

    The invention discloses a jet propulsion device and a test system thereof. The jet propulsion device comprises a cavity and a piston located in the cavity and capable of reciprocating in the cavity, the cavity comprises a shell and a plurality of annular coils arranged on the inner wall of the shell, the piston comprises a hollow piston body and a plurality of annular magnetic steel arranged on the outer wall of the piston body, and the annular magnetic steel and the piston body are integrally arranged, and the annular magnetic steel and the annular coil are matched to form an alternating-current permanent magnet synchronous linear motor. The alternating-current permanent magnet synchronous motor is adopted to directly drive the piston to operate, the driving current is small, the peak thrust of the motor can reach hundreds of N, the transmission efficiency is high, the jet speed is high, a driving part and the piston are integrally designed, and the structure is compact.
