Embodiment Construction

[0027] Other characteristics, objects and advantages of the present invention will become more apparent by reading the detailed description of non-limiting embodiments made with reference to the following drawings:

[0028] For the attitude-controlled gas generator with small free volume, controlling its ignition method and the strength of the plug at the outlet of the nozzle is an important factor in controlling the reliable ignition of the gas generator. In this example, the plug is controlled by the closure of the solenoid valve to realize the function , The ignition method adopts the jet type. By controlling the closing time of the jet gas and the solenoid valve, the ignition process can be effectively controlled according to the actual work needs, and the consistency and reliability of the ignition process can be realized.

[0029] This invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Abstract

The invention provides a reusable small-free-volume attitude-control ignition simulating device and method. The reusable small-free-volume attitude-control ignition simulating device and method comprises a reusable valve, a fuel gas generator simulating cavity shell, a pressure testing unit, an ignition unit, a free volume simulator with charges, a jet igniter and a spray pipe simulator; the reusable valve is used for simulating valve control during attitude-control work and used for controlling stopping and starting of a fuel gas simulating generator; the fuel gas generator simulating cavityshell is used for repeatedly bearing high-temperature and high-pressure hot fuel gas impact; the pressure testing unit is used for testing pressure data in the simulator; the ignition unit is used forigniting ignition powder of the jet igniter; the spray pipe simulator is used for simulating spray pipe conditions under the real working conditions; the jet igniter is used for rapidly igniting themain charge surface to ensure the consistency of capability releasing of the igniter; and the free volume simulator with the charges are used for simulating the ignition conditions of an attitude-control fuel gas generator under the real free volume conditions.

Description

technical field [0001] The invention relates to the field of solid rocket motors, in particular to a reusable small free volume attitude control ignition simulation device and method. Background technique [0002] With the development of solid attitude and orbit control engine technology, small attitude control switch valves are developing towards long-term high-frequency work. In order to ensure that the valve can work for a long time, the gas needs to be clean enough and the combustion temperature should not be too high. On the other hand, the attitude control system requires light structure, device integration, and miniaturization. With this refined design, higher requirements are put forward for the design of the gas generator. In order to ensure the improvement of the comprehensive performance of the system, the filling ratio of the gas generator needs to be higher, which makes the ignition free volume relatively small. Small. [0003] In addition, since the attitude ...
