Embodiment Construction

[0011] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0012] Such as figure 1 As shown, the gas generating device of the military fighter of the present invention includes a gas cylinder 1, an air combined pressure reducing valve 2, an air control valve 3, a fuel bottle 4, an excitation device 5, a gas generator 6, an ignition nozzle 7, and a fuel control valve 8. High-pressure pressure sensor 9, temperature sensor 10, and low-pressure pressure sensor 11. The outlet of gas cylinder 1 is connected to the inlet of air combined pressure reducing valve 2. The temperature sensor 10, pressure sensor 9 and inflation interface are located at the outlet of gas cylinder 1. The air The outlet 2 of the combined pressure reducing valve is connected to the air cavity port of the fuel bottle 4 and the inlet of the air control valve 3, the outlet of the li...

Abstract

The invention discloses a gas generator for a military aircraft. The gas generator comprises a gas cylinder, an air combined reducing valve, an air control valve, a fuel oil bottle, an exciting device, a gas generator, an ignition plug, a fuel oil control valve, a high-pressure sensor, a temperature sensor, a low-pressure sensor and the like. The gas generator can achieve two functions, working media are easily accessible air and aircraft fuel, two required working-condition gases can be output, a ground starting auxiliary power system of the military aircraft is realized, stable gas output is provided, and 'Bang-Bang' pulsed gas output is provided in case of a flight emergency.

Description

technical field [0001] The invention relates to a gas generating device, in particular to a gas generating device for military fighter planes. Background technique [0002] The gas generating device of a military fighter is an important part of the aircraft auxiliary power system (also known as the second power system), and is the starting point of the entire auxiliary power system. The auxiliary power system of the aircraft fighter urgently needs the gas with the temperature and pressure specified for ground start and the gas specified for flight emergency. Safety. At present, the gas generators equipped on my country's active fighters all use monocomponent hydrazine 70 to catalyze the decomposition and combustion to produce a pressured gas. The gas generating device is a one-off work, and cannot provide repeated, non-toxic gas for driving the turbine to do work for the ground-started aircraft auxiliary power unit. Contents of the invention [0003] The technical probl...
