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] Such as Figure 1 to 4 As shown, an electromagnetic mechanical insurance solid rocket engine igniter according to an embodiment of the present invention is located.

[0019] Compared to the regular ignitioner, an electromagnetic mechanical insurance solid rocket engine igniter adds an electromagnetic mechanical insurance.

[0020] Electromagnetic mechanical insurance is mainly composed of electromagnetic suction cup 1, electromagnetic suction cup power supply cable 3, gas airflow passage valve 11, spring 12; gas channel valve 11 is provided in the gas channel valve 11; the electromagnetic suction cup cable 3 is used to supply electromagnetic suction cups 1 of. Electromagnetic mechanical insurance is placed between the heating tube and the ignition kit.

[0021] The heating pipe is configured by the ignition press screw 4, the ignition cable 5, the pressure plate 6, the ignition head 7, the phenopteric 8, and the hephonic hole 9, and the heating tube is connected to the conne...

Abstract

The invention belongs to the technical field of solid rocket motors, and relates to an igniter of an electromagnetic mechanical insurance type solid rocket motor; in the invention, a set of electromagnetic mechanical insurance is placed in the gas fire transmission channel between the ignition tube and the ignition cartridge in the igniter, The opening and closing of the gas fire transmission channel is controlled by the electric signal control electromagnetic mechanical insurance, which not only realizes the safety control ignition control of the igniter, but also ensures that once the ignition system ignites by mistake, it will not cause the entire ignition device to ignite, which greatly improves the safety factor. , reduce the possibility of safety accidents, and further realize the electrification control of the mechanical safety device, which is safer and more convenient.

Description

Technical field [0001] The present invention belongs to the technical field of solid rocket engine involves an electromagnetic mechanical insurance solid rocket engine ignitioner. Background technique [0002] The igniter is a startup device for solid rocket engines. It is the most dangerous component. It is also the most prone to faulty components. The igniter is generally composed of a fire tube, an ignit cartridge (containing ignition drugs) and connecting seats, where the fire tube is The most sensitive part of the igniter. Human electrostatic electricity, electrostatic electricity, radar, radio and high voltage lines of electromagnetic radiation, as well as stray currents in battlefield and weapon system, etc., can cause accidental ignition of the heating tube, causing serious consequences. Therefore, the modern weapon system is constantly improving the safety characteristics of the heating tube; on the other hand, some security measures are also taken. For example, shielded...
