Abstract

The invention discloses an embedded type gas charging channel for supplementing gas for a gas charging channel based on a high-pressure gas cylinder. The embedded type gas charging channel comprises a gas charging hole, a gas discharging hole and a gas flow passage of a gas charging channel, wherein the gas charging hole is connected with the gas discharging hole by virtue of the gas flow passage of the gas charging channel; a gas spraying hole is formed in the inner wall of the gas flow passage of the gas charging channel and is communicated with the high-pressure gas cylinder by virtue of a gas flow guide pipe; the gas flow guide pipe is provided with an automatic control valve. According to the embedded type gas charging channel for supplementing gas for the gas charging channel based on the high-pressure gas cylinder, the gas spraying hole is formed in the gas flow passage of the gas charging channel; the gas in the high-pressure gas cylinder is supplemented for the gas charging channel by virtue of the gas flow guide pipe and the gas spraying hole; the total pressure recovery coefficient of the gas charging channel in a starting stage of an engine is increased; meanwhile, the gas flow is increased.

Description

technical field [0001] The invention relates to an embedded air inlet, in particular to an embedded air inlet used on an aircraft to supply air to the air inlet based on a high-pressure gas cylinder. Background technique [0002] The buried air inlet is a special air inlet that integrates the inlet and the aircraft without any protruding parts. The buried air intake can not only effectively reduce the wind resistance and radar scattering area of ​​the aircraft due to the small windward area, but also reduce the size of the missile body by integrating it with the missile body, which is conducive to installation, transportation and multi-platform launch. Therefore, the buried air intake is receiving more and more attention and application. [0003] Compared with conventional inlets such as S-shaped inlets, buried inlets have lower total pressure recovery and greater flow field distortion. Especially in the ignition stage of the engine, the total pressure recovery coefficient...
