Shulou(Shulou.com)11/24 Report--

Thanks to CTOnews.com netizens for the clue delivery of the holy Buddha! CTOnews.com March 25 news, according to Chongqing High-tech Zone news, recently, the Western (Chongqing) Science City detonation Propulsion and Aerospace Flight Technology Research Center successfully carried out 1000N kerosene fuel continuous rotary detonation engine ignition test.

Judged by the test data, the engine test reached the assessment target, and the test task was completed successfully.

(hereinafter referred to as the thrust-weight ratio engine Company) and the Industrial Technology Research Institute of Chongqing University (hereinafter referred to as the Major Industry and Research Institute) through the joint construction of detonation propulsion and space flight technology research center (hereinafter referred to as the research center) Committed to the professional development of detonation engine technology and products.

In August last year, the two H1murM continuous rotary detonation engines successfully completed the 100-meter track taxiing test and the 50N attitude control engine principle prototype test. Now only more than six months have passed, the team has once again achieved gratifying scientific research results-the first domestic 1000N continuous rotary detonation engine ignition test success! It indicates that the detonation engine industrialization of the thrust-to-weight ratio engine company is in the leading level in China.

The detonation Propulsion and Aerospace Flight Technology Research Center, together with the teacher team (research group) of the School of Aeronautics and Astronautics of Chongqing University, carried out key technical research and test work on 1000N continuous rotary detonation engine, and will carry out minute-level thermal test test in the near future to break through key technical problems such as thermal protection of engineering prototype development.

According to CTOnews.com query, Chongqing push weight ratio Power Technology Co., Ltd. was registered in September 2019. It is the first private enterprise in China to specialize in the development of detonation engines. The company focuses on product development in the field of aerospace defense and commercial aerospace. At present, the research and development and industrialization of supersonic target power system are mainly based on pulse detonation engine technology, which provides a low-cost and high-reliability detonation propulsion engine, which is used in the air target equipment market.

Detonation engine is a kind of low-cost new energy engine, and its cost can be reduced by more than half compared with the same gas turbine engine. Based on the core technology of detonation engine, it can realize the serialization of products with different thrust levels, which can cover 100kgf~2000kgf thrust levels, and can be widely used in supersonic aviation targets, military UAV, civil UAV, near space aircraft, aerospace aircraft and other fields.

In addition, NASA also successfully tested the full-size rotary detonation engine rotary detonation rocket engine (RDRE) this year. Unlike traditional rocket engines, the RDRE uses a supersonic combustion phenomenon called detonation to generate thrust, NASA said. This design can generate more power and use less fuel than today's propulsion systems, and has the potential to power human landers and interplanetary vehicles to reach deep space destinations such as the moon and Mars.
