Problems solved by technology

[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

Abstract

The invention discloses a double-pulse combustion device with a common-chamber time-sharing ignition output. The first-stage charging and the second-stage charging are installed in a shell component in series, a first-stage ignition component is installed on the shell component and is connected with the first-stage charging in a matching mode, a second-stage ignition component is installed on theshell component and is connected with the second-stage charging in a matching mode, the first-stage charging and the second-stage charging are separated into two independent combustion units by adopting a partition layer component, a one-way valve component is arranged between the first-stage charging and an exhaust port of the shell component, and the sealing end of the shell component adopts a snap ring component to fix end cover components to the shell body component, and the sealing is achieved. According to the technical scheme, the space utilization rate is improved, so that the charge quantity is increased, dynamic compensation of the gas quantity of a gas storage device is realized, insufficient inflation or overpressure is effectively avoided, the reliability of ignition gas production is improved, and the double-pulse combustion device has the advantages that the structure is compact and reasonable, the installation is simple, and the extended application is flexible.

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 room. 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 out...
