[0002] The current mature gas generators are mostly used to inflate the storage tank of the attitude control power system, pressurize the propellant storage tank or drive the turbine. Its technical characteristics are one-time charge, one-time start-up, fixed gas output, and inflation often occurs during the pressure building process. Insufficient or overpressure, it is impossible to dynamically compensate for temperature loss, and it is accompanied by large high-frequency impact vibration; in addition, single-chamber free-loading charges are mostly used, and the proportion of charge mass is low, which requires a large space and weight to meet the same gas production. Therefore, it is difficult to meet the applications with long battery life, low overload, controllable output and limited space

The invention discloses a double-pulse burner with time-sharing ignition output in a common chamber, wherein the primary charge and the secondary charge are installed in series in a casing part, and the primary ignition assembly is installed on the casing part and connected with the casing part. The first-stage powder charge is matched and connected, and the second-stage ignition assembly is installed on the shell part and connected with the second-stage powder charge. A one-way valve part is arranged between the charge and the exhaust port of the shell part; the sealing end of the shell part adopts a snap ring part to fix the end cover part on the shell part to realize sealing. Through the technical solution of the present invention, the utilization rate of space is improved, and the amount of charge is increased, the dynamic compensation of the gas volume of the gas storage device is realized, insufficient inflation or overpressure is effectively avoided, and the reliability of ignition and gas production is improved. And it has the advantages of compact and reasonable structure, simple installation, and flexible expansion and application.
Description
technical field [0001] The invention relates to the technical field of gas generators, in particular to a dual-pulse gas generator with time-sharing ignition output in a common chamber. Background technique [0002] The current mature gas generators are mostly used to inflate the storage tank of the attitude control power system, pressurize the propellant storage tank or drive the turbine. Its technical characteristics are one-time charge, one-time start-up, fixed gas output, and inflation often occurs during the pressure building process. Insufficient or overpressure, it is impossible to dynamically compensate for temperature loss, and it is accompanied by large high-frequency impact vibration; in addition, single-chamber free-loading charges are mostly used, and the proportion of charge mass is low, which requires a large space and weight to meet the same gas production. Therefore, it is difficult to meet the applications with long battery life, low overload, controllable ...
