The reporter learned from China Aerospace Science and Technology Group Co., Ltd. that my country's new generation manned carrier -carrier rocket three -level engine's first long -range ignition test has been successfully completed recently, marking the conditions for the engine to enter the initial development stage.
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 No. 6 test desk of the No. 101 of the 6th Hospital of China Aerospace Science and Technology Group, which undertakes this experiment, as a "rehearsal field" that witnessed the growth process of the Long March 5 carrier rocket core secondary engine. The flying dream of the engine.
According to reports, at present, the development steps and stages of rocket or spacecraft engineering are roughly: from "scheme" to "first" to "sample" to "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 test results analysis report, and make the conclusion whether to meet the requirements of the development task book.
