Fuel gas generator and testing device suitable for test of swallowing gunpowder gas by engine

Abstract

The invention provides a fuel gas generator and a testing device suitable for a test of swallowing gunpowder gas by an engine. The fuel gas generator comprises an ignition device, a combustor, a gas collection chamber and an exhaust nozzle, wherein the ignition device is arranged at one end of the fuel gas generator, a plurality of grains are installed in the combustor and are in contact with the ignition, the gas collection chamber is arranged outside the combustor, the combustor is covered with the gas collection chamber, and the exhaust nozzle is arranged at the other end of the fuel gas generator and communicates with the gas collection chamber. The fuel gas generator and the testing device are high in controllability, safe and stable in operation, capable of precisely simulating the environment of high-temperature gas ejected from rocket projectiles, guided missiles and other weapon exhaust nozzles, capable of meeting the demand of conducting the test of swallowing gunpowder gas by the engine or a test of sucking weapon exhaust gas when an aircraft and the engine are shaped, and fills up the vacancy in the special test field at home.

Description

technical field [0001] The invention relates to the field of engine testing devices, in particular to a gas generator suitable for the test of engines swallowing gunpowder gas. Background technique [0002] In combat, the high-temperature exhaust gas produced by the aircraft itself launching missiles, rockets and other weapons is easily inhaled by the aircraft engine, causing the engine intake temperature to rise sharply, resulting in engine intake distortion, performance deterioration, and power loss. Reducing the stable working envelope of the engine may even cause the engine to stall, surge, stall, and stop in the air, which will not only delay the fighter plane, but may also cause the plane to crash. Therefore, when the engine or aircraft is finalized, it is necessary to carry out the engine swallowing gunpowder gas test. [0003] The engine swallows gunpowder gas test, also known as the inhalation aircraft weapon exhaust test. The aircraft inhales the high-temperature...

AI Technical Summary

Problems solved by technology

However, the current test device cannot control the flow rate of the simulated high-temperature exhaust gas, which is dangerous during the test.
