Porous monocolumn fuel supply structure for supersonic vehicle ramjet

Abstract

The invention proposes a porous single-column fuel supply structure for supersonic aircraft ramjet, the structure includes a column structure and a base, the column structure is composed of a porous shell and a hollow support rod, and the porous shell is made of a porous material sintered with metal particles Composition, the porous shell is wrapped on the top of the hollow support rod and sintered into a cylindrical structure as a whole; the hollow support rod runs through the base, the inner longitudinally has an injection channel, and the bottom is provided with an injection port; the fuel enters the injection channel through the injection port, and then injected into the Inside the cavity of the columnar structure. The invention solves the problem that the fuel supply structure in the combustion chamber of the ramjet based on the central combustion stabilization technology cannot be cooled, and proposes a metal particle sintered porous single-column fuel supply structure for the supersonic aircraft ramjet, which uses metal particle sintered porous single-column The structure is fueled, and the fuel is used to achieve full-coverage sweat cooling of the structure.

Description

technical field [0001] The invention relates to a metal particle sintered porous single-column fuel supply structure for a ramjet engine of a supersonic aircraft, which is used in the ramjet engine of a supersonic aircraft to supply hydrocarbon fuel for a combustion chamber, and belongs to the technical field of ramjet. Background technique [0002] Supersonic aircraft is one of the key points of aircraft propulsion technology research in various countries in the world, and it is also one of the technical fields that are currently prioritized in the military development of various countries. The thermal protection system is an essential part of a high-speed sonic aircraft, which can ensure the normal operation of the aircraft in an extreme thermal environment. With the development of high-speed sonic aircraft, the maximum heat load faced by the aircraft has far exceeded the cooling capacity provided by traditional cooling technologies, especially the cooling of key component...
