my country's new generation of manned rockets three -level engines for the first long test of the first long -range test successful success

On June 14th, at 101 Hospitals of China Aerospace Science and Technology Group Co., Ltd., my country's new -generation manned carrier -carrier rocket three -level engine was successfully completed for the first time, marking that the engine has the transfer of the initial development stage. condition.

The engine is my country's first upper -stage hydroxide engine with a low -pressure torch ignition method. This test assessment key technologies such as engine and component status, torch ignition system work reliability, and real -time fault diagnosis system principle verification and other key technologies.

The 101 test description of the 101 test of this test was the "rehearsal field" that witnessed the growth process of the Long March 5 carrier rocket core secondary engine, and also entrusted the flying dream of a new generation of manned carrier rocket 3 -stage engine.

All participants have always adhered to the spirit of strict and careful, efficient cooperation, and continuous combat spirit. They only used 3 days to complete the test system transformation, completed the test preparations for 3 days, and finally completed the three test ignition tasks.

More knowledge

At present, the development steps and stages of rockets or spacecraft engineering are roughly: schemes → first -sample → sample → application launch. Among them, the scheme stage can be subdivided into scheme demonstration and plan development. Since then, it is the first development and the development of the sample.

The "initial" and "samples" phase are the development steps and stages of the development of aerospace type projects such as carrier rockets. The completion signs of these two stages are to complete the sample flight test verification according to the flight test scheme and the flight test outline, propose the analysis report of the test results, and make the conclusion whether to meet the requirements of the development task book.
