Design of Equipment Controlling Ignition of Gun of Superhigh Shoot Frequency

摘要

Appearance of “Metal Storm” of Australia definites newly the concept of high fire frequency. Simulation launch facility of gun with superhigh shoot frequency is composed of launch tube, in which several projectiles are arranged in turn, between these there are propellants. Cartrige drum is fixed at the back of launch tube and ignition node is mounted in turn on the tube, which connects with equipment of controlling shoot. Electrode on each ignition node, which contacts with ignition probe on cartridge drum, is insulating with gun tube .The process of firing is as follows: When Shooting, the electronic controllable equipment produces current according to shot mode and firing frequency, and sends these pulse compliably. This paper adopts Single Chip Micyoco to design equipment controlling ignition of gun of superhigh firing frequency. Because electric igniter has only several ohm resistances, but it requires bigger current to be ignited, and the equipment of controlling ignition does not need bigger current, so the equipment is composed of two parts: the one is facility of controlling firing current and the other is circuit of producing current.
