旋转稳定弹上用的供电电源应设计成能在旋转降低时开始为子弹提供可靠供电电能。为此安装了一个靠机械力点燃或激活的热电池。在子弹到自由飞行段后，止旋翼才能滑开，释放止动销，这时止动销向离心的方向移动，腔体内压紧的弹簧使击针体加速运动，从而点燃燃烧剂，激活热电池 The supply of power to the rotating stabilizer should be designed to start providing reliable power to the bullet as the rotation decreases. To this end installed a mechanical ignition or activation of the thermal battery. After the bullet reaches the free flight stage, the rotor can only slide open to release the stop pin. At this time, the stop pin moves toward the centrifugal direction, and the compressed spring in the cavity accelerates the firing pin body to ignite the combustion agent to activate the thermal battery
