Solid rocket powder supersonic combustion ramjet engine

Abstract

The invention discloses a solid rocket powder supersonic combustion ramjet engine. The solid rocket powder supersonic combustion ramjet engine comprises a gas inlet path, a fuel gas generator, a supersonic-velocity combustion chamber and a tail spray tube, and further comprises a powder supply system, wherein a powder spray-out hole which communicates with the powder supply system is formed in theinner wall of the gas inlet path; powder fuels output by the powder supply system are pushed to the gas inlet path through a powder spray-out hole; supersonic-velocity inflow air in the gas inlet path rolls and absorbs powder fuels, so that mixing of the fuel powder and the supersonic-velocity inflow air is realized, and the mixed fuel powder and supersonic-velocity inflow air enters the supersonic-velocity combustion chamber; and high-temperature high-pressure gas, generated in the supersonic-velocity combustion chamber, of the powder fuels and combustion-rich fuel gas does work by tail spray tube expanding to generate thrust force. The solid rocket powder supersonic combustion ramjet engine can realize active regulation on parameters such as supply amount and supply speed of the powderfuels through the powder supply device, has the advantage of adjustable thrust force, and enables an aircraft to have better maneuverability and a wider airspace range.

Description

technical field [0001] The invention relates to a ramjet in the aerospace field, in particular to a solid rocket powder scramjet. Background technique [0002] After entering the 21st century, human beings are developing towards the hypersonic era in aerospace technology. In the future, hypersonic aircraft flying in the atmosphere with a Mach number greater than 5 can effectively achieve penetration and rapid strike with its high speed and high maneuverability. The realization of the goal is mainly based on the advanced air-breathing propulsion system suitable for high Mach number flight. The United States and the world's major military and aerospace powers have conducted ground tests and flight verification tests of hypersonic vehicle power systems in the past decade or so, showing that scramjet engines can well meet this urgent demand. [0003] Scramjet is a cutting-edge technology involving many disciplines and many frontier fields. At present, the scramjet that has been...
