Problems solved by technology

It is difficult to completely shield the igniter of the solid rocket motor by using shielding measures and installing low-pass filters and other safety insurance agencies, that is, the igniter still fires by mistake, causing serious safety accidents. After a large number of analysis tests, it is shown that in The addition of a mechanical safety mechanism in the igniter can ensure that the igniter will not cause safety accidents due to misfiring. Usually the mechanical safety is often manually rotated, which is complicated and troublesome to use. Therefore, the new safe and easy-to-use mechanical solid rocket motor ignition to be developed

Embodiment Construction

[0018] like Figure 1 to Figure 4 Shown is an electromagnetic mechanical safety solid rocket motor igniter according to an embodiment of the present invention.

[0019] Compared with conventional igniters, an electromagnetic mechanical insurance type solid rocket motor igniter adds a set of electromagnetic mechanical insurance.

[0020] The electromagnetic mechanical insurance is mainly composed of an electromagnetic chuck 1, an electromagnetic chuck power supply cable 3, a gas fire transmission channel valve 11, and a spring 12; a gas fire transmission channel 10 is set in the gas channel valve 11; of. The electromagnetic mechanical insurance is placed between the firing tube and the ignition powder box.

[0021] Firing tube is formed as a whole by ignition pressure screw 4, ignition cable 5, bearing plate 6, ignition tip 7, firing powder 8 and firing hole 9, and firing tube is connected with connecting seat 2 by the screw thread on the ignition pressure screw 4. The ignit...

Abstract

The invention belongs to the technical field of solid rocket engines, and relates to an electromagnetic mechanical safety type solid rocket engine igniter. An electromagnetic mechanical safety deviceis arranged in a fuel gas ignition channel, between an ignition tube and an ignition powder cartridge, in the igniter, the electromagnetic mechanical safety device is controlled by an electric signalto control the fuel gas ignition channel to opened or closed, safe ignition control of the igniter is achieved, it is ensured that even if an ignition system ignites by mistake, ignition of the wholeignition device cannot be caused, the safety factor is greatly improved, the possibility of a safety accident is reduced, electrified control over the mechanical safety device is further improved, andthe igniter is safer and more convenient to use.

Description

technical field [0001] The invention belongs to the technical field of solid rocket motors, and relates to an igniter for electromagnetic mechanical safety solid rocket motors. Background technique [0002] The igniter is the starting device for the solid rocket motor. It is the most dangerous part and the most prone to failure. The igniter is generally composed of an ignition tube, an ignition cartridge (containing ignition powder) and a connecting seat. The ignition tube is The most sensitive part of the igniter. The static electricity of the human body and some plastic products, the strong magnetic field caused by the electromagnetic radiation of radar, radio and high-voltage lines, and the stray current on the battlefield and in the weapon system may cause accidental ignition of the firing tube, causing serious consequences. Therefore, on the one hand, modern weapon systems continuously improve the safety characteristics of the firing tube; on the other hand, some safet...
