Embodiment 1
[0026] see figure 1 and figure 2 , a magnetoresistive electromagnetic launch outlet deceleration suppression device, comprising a projectile 100 and an N-level acceleration module, where N is a natural number greater than 1;
[0027] The i-th acceleration module is composed of a front-stage transmitting coil 110 connected to a previous-stage control circuit 111;
[0028] The cathodes of the preceding freewheeling switch element 112 and the preceding discharge switching element 113 are connected to the marked end 1100 of the preceding transmitting coil 110; the anode of the preceding capacitor 114 is connected to the anode of the preceding discharge switching element 113, and the cathode is is connected to the unmarked end of the preceding stage transmitting coil 110; the anode of the preceding stage freewheeling switch element 112 is connected to the unmarked end of the preceding stage transmitting coil 110;
[0029] The i+1 th acceleration module is connected by a post-sta...
Embodiment 2
[0034] This embodiment is basically the same as the first embodiment, and the special features are as follows:
[0035] In this example, see figure 1 and figure 2 , the projectile 100 is cylindrical, and the axial length is the same as that of the transmitting coil, the diameter is smaller than that of the transmitting coil, and is made of ferromagnetic material.
[0036] In this embodiment, the front-stage transmitting coil 110 and the rear-stage transmitting coil 120 have the same axis in space, and are arranged in sequence according to the projectile 100 launching direction, and the distance between the transmitting coils is zero. The marked end 1100 of the front-stage transmitting coil is not the same name as the marked end 1200 of the subsequent-stage transmitting coil. The front-stage discharge switch element 113 and the back-stage discharge switch element 123 use thyristors; the front-stage freewheeling switch element 112 and the back-stage freewheeling switch elemen...
Embodiment 3
[0042] This embodiment is basically the same as the previous embodiment, and the special features are as follows:
[0043] In this example, see figure 1 and figure 2 , taking N as 2, it can be obtained as figure 2 Shown is the schematic diagram of the improved two-stage launch scheme. The two-stage transmitting coils are wound in the same way, not separated by a certain distance, and connected to the same circuit. The discharge of the capacitor is controlled by the discharge switching element, and the coil current is freewheeling through the switching element. The front-stage discharge switch element 113 is controlled to be turned on, and the projectile 100 starts to move. When the projectile moves to coincide with the midpoint of the front-stage coil 110 , the back-stage switch element 123 is triggered to conduct, and the current of the back-stage launch coil 120 rises rapidly. Under the action of mutual inductance, the current of the front-stage transmitting coil 110 dr...
