A double-pulse solid rocket motor wiring board assembly device

Abstract

The invention provides a wiring board combination of a double-pulse solid rocket motor, which comprises a wiring board, a wiring post, a spring, a pin and a flat washer. The terminal passes through the through hole on the side wall of the terminal board, and is fixed in the square hole of the terminal board together with the spring and the first and second pulse ignition device terminals. board. The terminal block assembly is fixed to the engine compartment with screws through countersunk holes at both ends of the terminal block. The advantages and beneficial effects are as follows: the structure is simple and the assembly is convenient; the first and second pulse ignition device terminals are pressed together by the spring pre-tightening force to make them stick together, the ignition circuit is connected reliably, and the electrical failure caused by the connector connection is reduced. The wiring board assembly plays a fixed and protective role on the cable; in addition, the identification between each ignition circuit is clear, which is convenient for checking the correctness of the circuit and ensuring the reliable operation of the solid rocket motor ignition circuit.

Description

technical field [0001] The invention relates to double-pulse solid rocket motor technology, in particular to an electrical connection and fixing structure of a double-pulse motor ignition device. Background technique [0002] In order to improve the performance of tactical missiles, increase the range, and rationally distribute and use energy, dual-pulse engine technology has been widely used. The dual-pulse motor achieves the rational use of solid rocket motor energy by controlling the ignition timing of the first and second pulses. [0003] A dual-pulse engine is generally composed of a two-pulse ignition device, a second-pulse combustion chamber, a compartment, a first-pulse ignition device, a first-pulse combustion chamber, and a nozzle. In order to adapt to the double-pulse engine structure, the engine ignition system is composed of a second-pulse ignition device, a first-pulse ignition device and a wiring board assembly, and the wiring board assembly is fixed on the c...

AI Technical Summary

Problems solved by technology

[0004] At present, there is a plan: the two ignition devices of the dual-pulse engine have not realized unified control on the bomb, the ignition signal of the first pulse is provided by the ground launch control system, and the ignition signal of the second pulse ignition device is provided by the control cabin on the bomb, so it can only be launched on the ground, which is limited The scope of use of dual-pulse engines
