Embodiment Construction

[0024] The implementation example applied to an emergency power system is as follows: The dual-mode gas generation device consists of a gas cylinder group 1, an air charging valve 2, an air cut-off and pressure reducing valve 3, a fuel storage tank 5, an oil filling valve 10, an air control valve 4, and a fuel cut-off valve. And control valve 6, gas generator 7, turbine 8 and control system 9, the system composition see figure 1 , the schematic diagram of the installation structure is shown in figure 2 .

[0025] The gas cylinder group adopts two cylindrical carbon fiber wound gas cylinders; the pressure cut-off and pressure relief valve are designed according to the working process of the system, only the pressure adjustment accuracy is required, and there is no working characteristic of the closed state. The pressure relief valve is designed with a metal-to-metal The structure simplifies the valve core and valve seat, and it is easy to ensure and realize the centering of t...

Abstract

The invention relates to a dual-mode gas generating device and a dual-mode gas generating method. The device comprises a gas cylinder assembly, an air stop and pressure reducing valve, a fuel oil storage tank, a fuel oil stop and control valve, an air control valve, a gas generator and a control system; gas in the gas cylinder assembly is output in two paths through the air stop and pressure reducing valve, one path of gas is output to the fuel oil storage tank, and the other path of gas is output to the gas generating device through the air control valve; and the fuel oil storage tank is communicated with the gas generator through the fuel oil stop and control valve. The device solves the technical problems that the conventional gas generating device can only be used once, has high cost and is complex to maintain; and when the device is used as a flight emergency power source, the device provides power for ground start of an auxiliary system, so that the system is simplified.

Description

technical field [0001] The invention relates to a dual-mode gas generating device and a generating method, in particular to a reusable gas that uses air and kerosene as a medium, drives a turbine through gas, and provides emergency electric energy and hydraulic energy for aircraft ground start and air emergency systems Generating device and generating party. Background technique [0002] The gas generation device used in traditional aircraft is a separate system. When the main power supply or main hydraulic pump system of the aircraft fails or the generator stops during flight, the emergency power system uses the compressed air extracted from the aircraft engine as power first. If the engine If the available compressed air is insufficient, the gas produced by the decomposition of monopropellant is used as a supplement to drive the turbine power plant to generate emergency hydraulic and electrical energy. [0003] The gas generating device adopting the above-mentioned scheme...
