A remote pressure relief structure for solid-liquid rocket motor

Abstract

The invention discloses a remote pressure relief structure of a solid-liquid rocket engine. The remote pressure relief structure comprises a remote pressure relief electromagnetic valve, a pressure relief pipeline and a discharge component, wherein the inlet end of the remote pressure relief electromagnetic valve is connected with a gas bottle, and the outlet end of the remote pressure relief electromagnetic valve is connected with the pressure relief pipeline; when the remote pressure relief electromagnetic valve is opened after receiving an instruction, gas enters the pressure relief pipeline through the remote pressure relief electromagnetic valve, and the pressure relief pipeline guides the high-pressure gas from the remote pressure relief electromagnetic valve to the discharge component mounted on the skin of the solid-liquid rocket engine; the discharge component is provided with a light hole section inside, and a membrane is arranged in the light hole section; the discharge component is further provided with a threaded section inside, a regulating gasket is mounted on the upper portion of the threaded section, and the regulating gasket compresses the membrane; the lower portion of the threaded section is used for being connected with the pressure relief pipeline; the high-pressure gas in a discharge port nut breaks through the membrane and is discharged. The remote pressure relief structure has the advantages that remote pressure relief under an emergency can be achieved, influence of the pressure relief process on equipment is low, and staff and equipment safety under the emergency can be guaranteed.

Description

technical field [0001] The invention belongs to the field of booster conveying systems for rocket engines, and in particular relates to a remote pressure relief structure for emergency pressure relief on rockets. Background technique [0002] The pressurization delivery system is a very important and complex part in the design of rockets and aircrafts, which has a great influence on the performance, safety and reliability of rockets and aircraft systems. [0003] Small and medium-sized solid-liquid rocket engines often use extrusion conveying systems, which generally include high-pressure gas cylinders, oxidant storage tanks, electric explosion valves, booster discharge valves and other components, and the outer walls of the gas cylinders and storage tanks are directly used as The aerodynamic shape of the rocket. [0004] After the filling and pressurization of the rocket is completed, it enters the process of waiting for launch. In an emergency, the launch process may be t...
