Integrated rocket ejector engine assembly and engine thereof

Abstract

The invention provides an integrated rocket ejector engine assembly. The integrated rocket ejector engine assembly comprises a stamping gas inlet path, three support plates and a rocket ejector, wherein the three support plates are separately an oxidant support plate, a fuel support plate and a voltage test circuit board; and the three support plates are used for hanging the rocket ejector in thestamping gas inlet path. The invention further provides a rocket based combined cycle engine. The integrated rocket ejector engine assembly can reduce the structural dimension, so that influences on air incoming flow are reduced.

Description

technical field [0001] The invention belongs to the field of rocket-based combined cycle (RBCC) engines, and relates to a small-sized integrated ejector rocket engine assembly and an engine thereof. The integrated ejection rocket engine of the present invention is mainly applicable to the ejection rocket engine using gas-oxygen / fuel in a rocket-based combined cycle (Rocket Based Combined Cycle, RBCC) engine. Background technique [0002] With the continuous exploration of the aerospace field in various countries, the rocket-based combined cycle (RBCC) engine has become one of the most likely to be used in the future space-to-ground propulsion system due to its advantages of reusability and low cost. The RBCC engine is mainly composed of a ram inlet, ejector rocket, ram afterburner, tail nozzle, etc.; the ejector rocket is an important part of the rocket-based combined cycle engine, and it is the main source of engine thrust in the ejection mode. . [0003] At present, coun...

Problems solved by technology

[0004] Among the above-mentioned different RBCC configuration schemes, the scheme in which the ejector rocket is arranged on the top wall of the exit of the isolation section has poor mixing between the primary flow and the secondary flow; the scheme in which the ejector rocket is arranged in the center of the combustion chamber does not consider the ejection Effect of Arrangement of Rocket in Ram Inlet on Incoming Air Flow

At the same time, none of the above schemes proposed the idea of ​​module installation from the test level, so as to facilitate the change of configuration at any time for testing
