Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings:

[0036] A gas-hydrogen / gas-oxygen vortex cooling thrust chamber injector proposed by the present invention, such as figure 1 As shown, it includes an injector head 1 , a spoiler 2 , an injection panel 3 , a combustion chamber 4 , a gas-oxygen injection ring 5 and a nozzle 6 .

[0037] like figure 2 , image 3 As shown, the injector head 1 is a flat plate structure with a groove A7 at the bottom. The injector head 1 has a plurality of through holes H20 evenly distributed on the outer edge of the groove A7, and the number of the through holes H20 Preferably more than 8; the central position of the injector head 1 has a through hole A8, a spark plug is installed in the through hole A8, and holes B9 and C10 are symmetrically distributed on both sides of the through hole A8, located in the holes B9 and C10 A ring-shaped gas-hydrogen liquid collecting chamber 23 is arrang...

Abstract

The invention provides a gaseous hydrogen/gaseous oxygen eddy current cooling thrust chamber injector, which comprises an injector head, a turbulent flow disc, an injection panel, a combustion chamber, a gaseous oxygen injection ring and an injection pipe. The injector has a simple structure, and a gaseous oxygen nozzle inclines upwards along the inner wall surface of the combustion chamber, so that the stability of external eddy current and the cooling effect are improved; the problem that the cooling effect is unsatisfactory because the wall surface temperature of the combustion chamber is high is solved; and the gaseous hydrogen/gaseous oxygen eddy current cooling thrust chamber injector can be applied to a thrust chamber with the thrust of 3,000N and the pressure of the combustion chamber of 2MPa.

Description

technical field [0001] The invention belongs to the technical field of liquid rocket engine propulsion, in particular to a gas-hydrogen / gas-oxygen vortex cooling thrust chamber injector. Background technique [0002] Thrust chamber vortex cooling technology is a new type of thrust chamber concept proposed by ORBITEC Corporation of the United States, which confines the propellant in the interior of two coaxially rotating vortex regions for mixing and combustion. The outer region of the vortex can prevent high-temperature combustion products and combustion. Indoor wall contact. The use of thrust chamber vortex cooling technology can solve the problem of severe thermal load on the surface of the combustion chamber due to propellant combustion. [0003] Compared with the traditional regenerative cooling method, the vortex cooling thrust chamber technology mainly has the following characteristics: (1) reducing the pressure loss of the coolant used for regenerative cooling; (2) i...
