The invention discloses a compressed air auxiliary power system, which mainly includes two gas storage tanks (high-pressure gas storage tank and low-pressure gas storage tank), a control valve, and a pressure detection and valve control unit. When the ejection system is working, the low-pressure gas storage tank first supplies air to the power cylinder to drive the ejection piston. Due to the relatively low pressure, it can control the acceleration of the ejected body within a reasonable range and protect the equipment of the ejected device; when the low-pressure gas storage After the tank pressure decreases to a certain value, the high-pressure air storage tank starts to supply air. After the high-pressure air passes through the low-pressure air storage tank and the cylinder buffer, its pressure will drop to a reasonable range and continue to drive the piston. The high-pressure air storage tank will With a relatively high energy storage density, it can increase the energy storage density of the gas storage device of the entire ejection system, maintain the stability and continuity of the acceleration during the ejection process, and increase the final ejection speed of the ejection device under reasonable ejection acceleration conditions.
Description
Technical field [0001] The present invention relates to a compressed air auxiliary power system, that is, by integrated high, low pressure gas storage tank, memory compressed air, and driving the ejection power piston, thereby completing the ejection task. Background technique [0002] The elastic system is borrowed from external power sources, providing initial takeoff or emission speeds such as aeroats, exploration rockets, missiles, which have important application value in modern defense and civil engineering. [0003] The elastic system has an important application value in the drone. Since the actual role in the field of military (intelligence reconnaissance, attack combat, etc.), industrial application (forest fire prevention, earthquake investigation, etc.) and consumer-based applications (personal aerial photography, celebration aerial photography, etc.) have been rapidly developed in recent years . At present, 32 countries including the United States, Israel, Canada, Ru...
