The invention provides a parallel linear motor catapult, and belongs to the field of electromagnetic catapulting, the parallel linear motor catapult is composed of two linear motors of the same structure, each linear motor comprises a plurality of stator modules, a rotor and a guide rail, and further comprises a coil sliding strip, a power source sliding strip and a feeler lever; the stator modules are evenly arranged in the direction of the rail, each stator module is composed of two U-shaped electromagnets, and the rotor is arranged in the middle of the stator modules and connected with the guide rail. According to the parallel linear motor catapult provided by the invention, the stator module is intermittently electrified, and the two linear motors are matched to work, so that the thrust is not interrupted. The catapult accelerates the rotor by simultaneously utilizing attraction and repulsion effects of magnetic force, has the characteristics of large catapult thrust, high efficiency, high reliability and low manufacturing cost, and can be used for catapult of objects such as shipboard aircrafts and unmanned aerial vehicles.

    本发明提供了一种并列直线电机弹射器,属于电磁弹射领域,由两个结构相同的直线电机组成,直线电机包括若干个定子模块、动子、导轨,还包括线圈滑条、电源滑条和触杆;定子模块沿轨道方向均匀排列,定子模块由两个U形电磁铁组成,动子设置在定子模块中间,动子与导轨连接。本发明提供的一种并列直线电机弹射器采用间断式地给定子模块通电,两个直线电机配合工作,使得推力不中断。这种弹射器同时利用磁力的相吸和相斥作用,将动子加速,具有弹射推力大,效率高,可靠性高和造价低的特点,可用于弹射舰载机、无人机等物体。
