Super-conducting electromagnetic pump circulating system of liquid rocket engine

Abstract

A super-conducting electromagnetic pump circulating system of a liquid rocket engine is a pump-fed circulating system built on the basis of the super-conducting technique and the magnetofluid generator technique and applied to the liquid rocket engine utilizing cryogenic propellants. A magnetofluid component arranged at the throttle of a thrust chamber of the liquid rocket engine transforms one portion of heat energy of gas of the engine into electric energy, and then the electric energy is transmitted to a super-conducing electromagnetic pump. The super-conducting electromagnetic pump is driven by the electric energy, and an impeller thereof rotates in a high speed, thereby increasing pressure of fuel or oxidants. The super-conducting electromagnetic pump circulating system of a liquid rocket engine is high in performance and reliability and strong in reusability, and is easy to realize multiple starting.

Description

【Technical field】 [0001] The invention relates to a circulation system of a liquid rocket engine, which is a pump pressure circulation system different from a turbo pump circulation established on the basis of a magnetic fluid generator technology and a high temperature superconducting technology. 【Background technique】 [0002] At present, most of the circulation systems of large liquid rocket engines are turbo pump circulation systems, and the turbo pump circulation is divided into two types: open cycle and closed cycle. [0003] Gas generator cycle (Gas Generator cycle, GG) is the most common open cycle, and its system diagram is as follows figure 1 shown. The system includes a fuel pump 3 , an oxidant pump 4 , a gas generator 5 , a fuel turbine 6 , an oxidant turbine 7 , a thrust chamber 8 , and gas nozzles 9 and 10 after the turbine. The direction of the arrow in the figure represents the flow direction of the propellant in the pipeline. Fuel and oxidant enter from f...

AI Technical Summary

Problems solved by technology

However, the afterburning cycle engine system is more complex, and because all components work under higher pressure, the engine structure is heavier

[0005] The technical difficulty of the open cycle system is small, the technology is mature, and the cost of engine design and manufacture is low, but due to the bypass loss, the propellant is not fully utilized, so the performance of the engine is not high

The closed cycle system solves the problem of open cycle bypass loss, the propellant can be fully utilized, the performance of the engine is high, but the technology is difficult, and the cost of engine design and manufacturing is high
