Abstract

The present invention relates to the technical field of fluid emergency discharge, in particular to a fluid discharge device, comprising: a discharge pipe with a fluid inlet and a fluid outlet; The fluid in the discharge pipe flows out according to a predetermined path, and the first position is blocked with the fluid outlet of the discharge pipe and the second position is opened to guide the fluid in the discharge pipe to flow out along the flow guide surface. Position; supporting structure, which is arranged corresponding to the flow guiding structure, and provides sufficient force to support the flow guiding surface when the flow guiding structure is in the second position. The invention provides a fluid discharge device which avoids the direct impact on the ground when the fluid is discharged, reduces potential safety hazards and improves the discharge speed.

Description

technical field [0001] The invention relates to the technical field of fluid emergency discharge, in particular to a fluid discharge device. Background technique [0002] Throughout the history of aerospace development, it can be seen that the pace of human space exploration and the development of cryogenic propellant engines are basically the same. Since the 1950s, continuous breakthroughs in high-thrust liquid oxygen kerosene engine and hydrogen-oxygen engine technology have supported the launch and application of iconic spacecraft such as space shuttles and space stations. At present, in terms of the active power of the launch vehicle, the two are still considered to be the optimal energy combination. On the other hand, in terms of reusable vehicle power, the liquid oxygen methane engine stands out because of its relatively high specific impulse, less coking in the combustion process, low cost, and good regenerative cooling performance. At the same time, low-temperature...
