Embodiment Construction

[0016] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0017] The invention provides a wiring board combination device of a double-pulse engine ignition device, such as figure 1 As shown, the wiring board assembly is fixed on the double-pulse engine compartment by screws, and can reliably connect the one- and two-pulse ignition devices. The solid rocket motor wiring board assembly includes: a wiring board 1 , a terminal post 2 , a spring 3 , a pin 4 and a flat washer 5 . The terminal 2 passes through the through hole on the side wall of the terminal board 1, and is fixed in the rectangular through hole of the terminal board 1 together with the spring 3 and the lugs of the first and second pulse ignition devices. The lugs are squeezed tightly by the spring preload Paste together; put the other end of terminal 2 on the terminal board with pin 4 and flat washer 5.

Abstract

The invention provides a double-pulse solid rocket engine wiring board combination device. The device comprises a wiring board, a binding post, a spring, a pin and a flat washer. The binding post passes through a through hole in the side wall of the wiring board and is fixed in a square hole of the wiring board together with the spring, a first pulse ignition device lug plate and a second pulse ignition device lug plate, and finally the small end of the binding post is fixed on the wiring board through the flat washer and the pin. The wiring board combination device is fixed on an engine compartment by screws through counter bores at two ends of the wiring board. The device has the advantages and beneficial effects that the structure is simple and the assembly is convenient; the first pulse ignition device lug plate and the second pulse ignition device lug plate are extruded through a pre-tightening force of the spring to be tightly attached together, ignition circuits are reliably connected, and electric appliance fault modes caused by connector connection are reduced; the wiring board assembly plays a role in fixing and protecting the cable; in addition, identifications among theignition circuits are clear, correctness of circuits is convenient to check, and reliability of work of the solid rocket engine ignition circuit is guaranteed.

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...
