Abstract

The invention provides a combined multifunctional combustion device, which includes several combustion test pieces arranged in parallel and a propellant supply system; The oxidant inlets of the test pieces are connected respectively; the oxidant flow regulating element is arranged on the pipeline connecting the oxidant storage tank and the oxidant inlet of each combustion test piece; the propellant supply system also includes a fuel storage tank, and the fuel storage tank passes through the pipe The pipelines are respectively connected to the fuel inlets of several combustion test pieces; the fuel flow regulating elements are arranged on the pipelines connecting the fuel storage tank and the fuel inlets of each combustion test piece. The invention adopts the parallel test of the segmented series combined combustion device, which can realize the multifunctional measurement of combustion efficiency and heat flow distribution; the axial length of the combustion chamber can be adjusted, and the different injector schemes under the same working conditions can be realized to the greatest extent A performance comparison study.

Description

technical field [0001] The invention relates to a segmented series combined combustion device which is suitable for performance research of a high-pressure and large-heat-flow thrust chamber of a liquid rocket engine and can realize multi-functional measurements such as combustion efficiency, heat-flow distribution and acoustic characteristics. Background technique [0002] At present, my country does not yet have the conditions for high-pressure extrusion hot test run of the thrust chamber of a large-thrust liquid rocket engine. Therefore, in order to optimize the design of the thrust chamber and improve the combustion performance, the simulation research can only be carried out through the hot test run of a single nozzle or a reduced-scale injector. . Research results at home and abroad in recent years have shown that many injector structural details, including oxidizer nozzle retraction, outlet diameter, outlet pipe wall thickness, fuel nozzle annular gap and single nozzle...
