Thanks to CTOnews.com netizen xiaocluoyuzi for the clue delivery! CTOnews.com news on January 6, according to the latest news of the Beijing Institute of Aerospace Power of the sixth Institute of Aerospace Science and Technology, the new power research team of the cryogenic liquid propulsion technology laboratory of the institute recently completed the first test of a hydrogen-oxygen continuous detonation rocket engine (OHCDRE) in the Yungang test area of Beijing. The test formed a stable and self-sustaining single-wave detonation wave with a detonation wave propagation velocity of 2200m / s. The combustion efficiency is greatly improved compared with the traditional deflagration combustion, and the test achieves the expected goal.

According to reports, the research team will further carry out continuous detonation research under the combination of various injection schemes and combustion chamber schemes, continue to explore the potential of hydrogen and oxygen continuous detonation engines, and promote the engineering application of continuous detonation engines.

According to the official introduction, the hydrogen-oxygen continuous detonation rocket engine is a new type of power engine, which can give full play to the fuel advantages of hydrogen-oxygen propellant with high specific impulse performance.

Continuous detonation combustion is a kind of pressurized combustion, in which the propellant is injected from the head of the combustion chamber and mixed rapidly, and the propellant is detonated by means of pre-detonation tube or spark plug to form one or more detonation waves rotating continuously along the circumferential direction in the combustion chamber; after the follow-up propellant is injected into the combustion chamber, it is transformed into combustion products of high temperature and high pressure under the action of continuous detonation waves, and expands and accelerates along the axial direction, and is ejected at a high speed through the nozzle to produce thrust.

CTOnews.com has learned that the propagation velocity of detonation wave can reach two or three kilometers per second, which can consume more propellant in a shorter time than traditional isobaric combustion, the size of combustion chamber can be greatly reduced, and the detonation pressurized combustion characteristics can greatly improve the specific impulse and thrust-weight ratio performance of the engine.
