Embodiment Construction
[0017] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0018] This embodiment is realized through the following technical solutions, as figure 1 As shown, an electromagnetic coil launcher for repeated use of an armature includes: a multi-stage coil 1, a launch tube 2, a package 3, an armature 4, a load 5, a connector 9, an adapter 6, a head reducer 7 and a tail Reducer 8 and other components.
[0019] The coils 1 are arranged on the launch tube 2 in turn, and the coils are packaged by the package 3 to achieve electrical insulation and mechanical reinforcement; the head of the launch tube 2 is longer than the last coil by two or more coils; the armature 4 is located on the launch tube. In the middle of the barrel, its initial position is usually in the middle of the first stage of the coil 1, and the tail of the armature 4 can be placed on the tail reducer 8; the armature 4 and the load 5 are connected thr...

The invention relates to pulse power techniques, in particular to an armature-reusable electromagnetic coil emitter and an emitting method. The emitter comprises a multi-stage coil, an armature, a load, a connector, an emitting canister, an adapter, a head reducer, a tail reducer and a drive circuit. The emitting method includes the steps that during the initial stage, the armature and the load are connected through the connector; when the coil is energized, the armature is subjected to electrodynamic force after current is induced, the load is pushed to move in the emitting canister, when thearmature reaches the maximum speed, the connector is disconnected, the armature is separated from the load, the load flies out of the emitting canister at the maximum speed, and the armature is decelerated by the drag force of the armature; if the armature speed is positive, the armature automatically falls to a tail part after hitting the head reducer, the recovery of the armature is realized; if the armature reaches the reverse speed, the armature hits the tail reducer to stop; the recovery of the armature is also achieved; and then the load is added for the next emitting. This method can realize the recovery and reuse of the armature.
Description
technical field [0001] The invention belongs to the technical field of pulse power, in particular to an electromagnetic coil transmitter and a transmitting method for repeated use of an armature. Background technique [0002] The electromagnetic coil transmitter is an accelerator composed of one or more coils. The coils at all levels are fed by pulse capacitors. The coils at all levels are ignited according to time or armature position, so that induced current and electromagnetic force are generated inside the conductor armature. , the armature pushes the load to a specified speed. The electromagnetic coil launcher needs to use the armature to push the load. At present, there are two main methods: one is that the armature and the load are integrated, and the armature will be launched together with the load every time it is launched. Due to the drag effect of the armature, the load exits The speed will be less than the peak speed, and the payload of the exit will be reduced,...
