Continuous rotation detonation rocket engine manufactured by additive manufacturing and additive manufacturing method thereof

Abstract

The invention relates to the technical field of aerospace equipment, in particular to a continuous rotation detonation rocket engine manufactured by additive design and manufacturing. The continuous rotation detonation rocket engine comprises an inner cylinder 2 of a rocket engine, a fuel injection unit 4, an oxidant annular cavity 5 and an oxidant gas collection chamber 10, wherein the fuel injection unit 4, the oxidant annular cavity 5 and the oxidant gas collection chamber 10 are connected with the inner cylinder 2 of the rocket engine; the inner cylinder 2, the fuel injection unit 4, the oxidant annular cavity 5 and the oxidant gas collection chamber 10 are integrated into an integral piece by additive manufacturing technology; and the space between a rocket engine casing 1 and the integral piece is a combustion chamber 7, and the rocket engine casing 1 and the integral piece are connected through positioning pins 9. The invention further relates to an additive manufacturing methodfor manufacturing the continuous rotation detonation rocket engine. The continuous rotation detonation rocket engine is integrally manufactured through the additive manufacturing technology, supportand connection structures between various components are reduced, machining is facilitated, and weight reduction and the reduction of the cost and difficulty of machining and maintenance are facilitated.

Description

technical field [0001] The invention relates to the technical field of aerospace equipment, in particular to a continuously rotating detonation rocket engine manufactured by additive manufacturing and an additive manufacturing method thereof. Background technique [0002] In recent years, more and more concepts of continuous rotating detonation rocket engines have emerged in front of people. Because the continuously rotating detonation rocket engine can give full play to the performance advantage brought by detonation combustion. As far as the traditional rocket engine is concerned, a booster pump is needed to supply fuel and oxidant to the rocket engine, which only makes the entire rocket engine system very complicated. However, the continuous rotation detonation rocket engine takes advantage of the self-pressurization of detonation, which reduces the dependence of the rocket engine on the booster pump and simplifies the structure of the entire rocket engine system.
