Problems solved by technology
[0004] Existing cold air propulsion systems generally need to connect multiple valves such as stop valves, pressure reducers, filters, one-way valves, solenoid valves, etc., using multiple "pipelines + joints" connections, and the work process is relatively complicated. Involving multi-segment pipelines and multi-valve series continuous action, failure of any part may lead to system failure. At the same time, such a system layout has strict requirements on space, requiring a larger space for testing product installation and piping. road layout

Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0032] A cold air propulsion system such as figure 1 As shown, it includes a gas cylinder group 1001, a combination valve 1002, a multi-channel pipeline 1003 and a thruster unit 1004 connected in sequence, wherein the gas cylinder group 1001 includes at least one gas cylinder, and if one gas cylinder is used, the combination valve 1002 directly It is installed on a single gas cylinder and communicated with the gas cylinder. If multiple gas cylinders are used, multiple pipelines are used for confluence and then communicated with the combined valve 1002. The combination valve 1002 is highly integrated and has the functions of a stop valve, a one-way valve, a pressure reducer and a solenoid valve. The multi-channel pipeline 1003 is selected according to the number of thrusters in the thruster unit 1004. Specifically, if the thruster unit 1004 When a propeller i...

The invention relates to a cold air propelling system. The invention belongs to the technical field of propulsion systems. According to the technical scheme, the cold air propelling system is provided. The device comprises a gas cylinder group formed by at least one gas cylinder, the gas cylinder group is communicated with a combination valve; an inflation one-way valve used for one-way inflation,a commanding type pressure reducer and a main pressure reducer used for overpressure safety protection, a main electromagnetic valve and a commanding type electromagnetic valve used for conducting electric control deflation on a gas cylinder are integrated in the combination valve. And the outlet of the combination valve is communicated with a thruster unit formed by at least one thruster, so that the effects of simplifying the structure of the existing cold air propulsion system and reducing the occupied space are achieved.
Description
technical field [0001] The invention relates to the technical field of propulsion systems, in particular to a cold air propulsion system. Background technique [0002] Spacecraft propulsion systems include cold air propulsion systems, solid propulsion systems, liquid propulsion systems (single-component, dual-component, dual-mode, hybrid), electric propulsion systems, etc. The cold gas propulsion system uses high-pressure gas to expand and accelerate the ejection directly through the nozzle to generate thrust. The thruster converts pressure energy into flow kinetic energy and ejects without any chemical reaction. Cold gas propulsion generally chooses inert gas nitrogen or helium as the working medium. The main feature is that there is no chemical reaction such as combustion. The system is particularly simple, low cost, high reliability, and the inert working medium has no heat, no explosion hazard, and no pollution. The cold air propulsion system is often used in the space...
