Embodiment Construction

[0029] Below with reference to accompanying drawing, illustrate the embodiment of the double working condition gas generant grain column related to the invention.

[0030] see figure 1 , a double working condition gas generating agent powder column, the gas generating agent 3 is installed in the heat insulating sleeve 1, the center of the gas generating agent 3 is provided with a high-burning rate drug strip 4, and the surface of the gas generating agent 3 is provided with There are an inner ring combustion-supporting groove 5 and an outer ring combustion-supporting groove 6 , and a liner 2 is provided at the side of the gas generating agent 3 in contact with the heat insulating sleeve 1 .

[0031] In this embodiment, the gas generating agent 3 is poured into the heat insulating sleeve 1, and the high-burning rate medicine strip 4 is placed in the gas generating agent 3, and the central axis of the high-burning rate medicine strip 4 and the central axis of the gas generating a...

Abstract

The invention relates to a dual-working-condition gas generating agent powder column. The gas generating agent is installed in a heat-insulating sleeve. The center of the gas generating agent is provided with a high-burning-velocity drug strip, and the surface of the gas generating agent is provided with an inner ring. The combustion-supporting groove and the outer ring combustion-supporting groove, a liner is provided at the side where the side of the gas generating agent is in contact with the heat insulating sleeve. The gas generating agent grain under dual working conditions starts to burn simultaneously from the surface of the gas generating agent, the surface of the combustion-supporting groove and the surface of the high-burning rate grain, and the burning surface shows a slow decreasing trend, and this trend lasts for a long time. The invention is used in a missile servo power device, and has the advantages of low combustion temperature, long duration of slowing down tendency of the combustion surface, multi-stage charge and multi-working-condition pressure through a single combustion rate charge, and the like.

Description

technical field [0001] The invention relates to a dual-working-condition gas generant grain column that provides working energy for a servo power device of a missile weapon type. Background technique [0002] At present, the servo power forms of missiles at home and abroad mainly include: compressed air type, gas type, and electric type. Among them, the volume of compressed air and electric equipment is too large, which is not convenient for transportation and mobile launch. The volume of the gas type device is much smaller than that of the compressed air type, and it has a wide range of applications. It is currently the main power form used by missile servo devices in various countries. In order to achieve precise control of missile thrust, under the condition of limited space and fixed nozzle, strict requirements are put forward for the servo system. It is necessary to achieve low gas temperature and high performance reliability. The working pressure of the grain, the pr...
