Although the first and second private rocket launches of China's LandSpace and OneSpace have failed, the private rockets continue to work hard. Official news from Blue Arrow said that the joint test of the "Tianqi" (TQ-12) 80-ton liquid oxygen methane engine semi-system has been a complete success recently. The test data shows that the design scheme is reliable and the product performance is stable.
It is reported that the semi-system ignition test run was carried out on the Blue Arrow Aerospace Hot Test Stand. The test device includes a turbo pump, gas generator, various valves, ignition and starting devices, and final assembly pipelines in addition to the thrust chamber. All core components The stability of the system has passed the assessment at one time.
Blue Arrow said that the success of this test has verified the feasibility of the design and process plan of the turbo pump and various valves, the coordination and matching of the system, and the correctness of the starting sequence, which has laid the foundation for the test run of the whole machine.
On October 27, 2018, China's first civilian-operated rocket Blue Arrow Space Launched at the Jiuquan Satellite Launch Center. The third-level abnormality occurred after 402 seconds of launch. Get on track according to the scheduled plan.
Lanjian Space said that the preliminary analysis believed that the failure was due to damage to the thrust tube of the final repair attitude control power system, which led to a decrease in control force and leakage of propellant, abnormal attitude control force, and early exhaustion of propellant.
H section steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section. Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices, etc., are regulated by standards in most industrialized countries.
