Embodiment Construction

[0028] Below with reference to accompanying drawing, illustrate the embodiment of the double working condition gas generant grain column related to the invention.

[0029] see figure 1 , a double-working condition gas generating agent powder column, the gas generating agent 3 is installed in the coating sleeve 1, and the middle part of the surface of the gas generating agent 3 is provided with a pointed combustion-supporting groove 4, and the outer sides of the pointed-shaped combustion-supporting groove 4 are successively An inner ring combustion-supporting groove 5 and an outer ring combustion-supporting groove 6 are provided, and a liner 2 is provided at the side of the gas generating agent 3 in contact with the coating sleeve 1 .

[0030] In this embodiment, the gas generating agent 3 is poured into the coating sleeve 1, and the high-burning rate drug rod is placed in the gas generating agent 3. The surface of the gas generating agent is provided with a pointed combustion-...

Abstract

The invention relates to a double-working-condition gas generator propellant grain. A gas generator propellant is contained in a wrapping sleeve. The middle of the surface of the gas generator propellant is provided with a sharp combustion supporting groove. An inner ring combustion supporting groove and an outer ring combustion supporting groove are sequentially arranged outside the sharp combustion supporting groove. A lining layer is arranged at the contact portion between the side face of the gas generator propellant and the wrapping sleeve. The double-working-condition gas generator propellant grain starts combustion on the surface of the gas generator propellant and the surface of the combustion supporting groove at the same time, the combustion surface is large in the early stage, the combustion surface tends to be reduced after 12 seconds, and the combustion surface tends to be stable after 16 seconds. The double-working-condition gas generator propellant grain is used for a guided missile servo power device and has the advantages of being low in combustion temperature, changeable in combustion surface, capable of achieving double-working-condition pressures of two-graded charge through 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. work pressure. In order to solve this pr...
