An air-to-air missile solid rocket motor ignition safety device return mechanism

Abstract

The invention relates to an ignition safety device, in particular to a return mechanism of an air-to-air missile solid rocket motor ignition safety device. The return mechanism of the air-to-air missile solid rocket motor ignition safety device of the present invention is arranged on the ignition safety device, and it is composed of a follower screw, a tension spring, a fixing screw and a spring support. Wherein, the ends of the two torsion arms of the tension spring are torsion arm earrings, the first torsion arm earring is inserted into the follower screw, and the second torsion arm earring is inserted into the fixing screw, and the fixing screw is arranged on the spring support , and the spring support is fixedly arranged on the ignition safety device, and the follower screw is connected with the ignition safety device. When the tension spring is deformed, it can provide thrust for the follower screw, which can be converted into a torque greater than the friction torque of the ignition safety device, preventing the ignition safety device from staying in the middle position outside the safe position and the combat position, thereby effectively avoiding air-to-air Misfired missiles occurred, increasing safety.

Description

An air-to-air missile solid rocket motor ignition safety device return mechanism technical field The invention relates to an ignition safety device, in particular to a return mechanism of an air-to-air missile solid rocket motor ignition safety device. Background technique Ignition safety device is a device to prevent accidental ignition of the ignition system. The ignition safety device and the ignition cartridge are physically separated from the ignition path through a mechanical explosion-proof mechanism, and then the ignition circuit is connected through the mechanical structure according to the environmental conditions to release the safety. The ignition safety device return mechanism is a mechanism that ensures that the ignition safety device can work reliably. The return mechanism of the ignition safety device can enable the ignition safety device to be reliably located in a safe position or a combat position according to operational needs. When the ignition safet...

AI Technical Summary

Problems solved by technology

However, due to the limitations of structural principles, the return mechanism usually has the problems of large volume, heavy weight, high cost and poor versatility

Ordinary return mechanisms are difficult to meet the requirements of air-to-air missiles, especially close combat air-to-air missile engine ignition systems with miniaturized ignition safety devices.

However, there is no public report on the return mechanism of the ignition safety device of the ignition system of the air-to-air missile engine in short-range combat.
