The invention discloses a rotary gas explosion sound source. The sound source comprises a stator, a rotor, a piston and a controller, wherein the rotor is installed in the stator and driven by the motor to rotate relative to the stator, release openings distributed in the circumferential direction are machined in the corresponding positions of the stator and the rotor, the piston is matched with an inner hole of the rotor and located in the stator, the stator is provided with an inflation inlet and an electromagnetic valve connector, the inflation inlet is communicated with an inner cavity ofthe stator, and the electromagnetic valve connector is communicated with a closed cavity defined by the piston and the stator, and the controller controls the pressure in an air cylinder and the movement position of the piston by controlling the on-off of the electromagnetic valve, so that an air gun array formed by different numbers of release openings is controlled to release high-pressure air,and different sound fields are generated to simulate ship noise.
本发明公开了一种旋转式气爆声源,声源包括定子、转子、活塞和控制器;转子安装在定子内部,转子通过电机驱动相对定子旋转,定子和转子上相对应的位置均加工有沿周向和周向分布的释放口;活塞与转子的内孔配合且位于定子内部,定子上设有充气口和电磁阀接口,充气口与定子内部空腔相通,所述电磁阀接口与活塞和定子合围形成的密闭空腔相通;控制器通过控制电磁阀的通断来控制气缸内的压力和活塞的运动位置,从而控制不同数量的释放口形成的气枪阵列释放高压气体,产生不同的声场模拟舰船噪声。
