At 0230 Hours Hong Kong SAR- Beijing Time 6TH September 2024 , China- People’s Republic of China- CNSA –China National Space Administration Successfully launched Chang Zheng – Long March 6 Yao 11 Carrier Rocket ignited and took off at the Taiyuan Satellite Launch Center Shanxi Province.. Successfully launch China successfully launched the Geely Constellation 03 satellites Satellite Successfully into its pre-determined orbit…
This mission is the 534th flight of the Long March series of carrier rockets. As the first liquid carrier rocket in China to adopt the “three-level” test and launch mode, the Long March 6 insists on improving and optimizing on the basis of the existing first set of overall transportation and erection systems. This mission uses the newly developed second set of overall transportation and erection systems for the first time. While improving the convenience of operation and environmental adaptability, redundant design and testability design are added to key links to shorten the docking, erection and landing time by 2/3, effectively improving the work efficiency of the launch site.
The third orbital satellite of Geely’s Future Mobility Constellation was successfully launched at the Taiyuan Satellite Launch Center with 10 satellites in one launch. Currently, 30 satellites of Geely’s Future Mobility Constellation are in orbit….
The Long March 6 is a small liquid carrier rocket with a three-stage tandem configuration. The first and second stages use liquid oxygen/kerosene engines, and the third stage uses nitrogen tetroxide/undimethylhydrazine propellants. The rocket is 29.932 meters high, with a first-stage diameter of 3.35 meters, and second and third-stage diameters of 2.25 meters. It can be equipped with 2.6-meter and 2.9-meter diameter fairings. The takeoff mass is about 102 tons, and the takeoff thrust is 122 tons. Its low-Earth orbit (LEO) capacity is greater than 1.5 tons, and the 700-kilometer circular sun-synchronous orbit (SSO) capacity is 1 ton.
The Long March 6 is the first flight model of China’s new generation of Long March carrier rockets. On September 20, 2015, the Long March 6 (Yao-1) carrier rocket successfully completed its maiden flight at the Taiyuan Launch Center, marking the entry of the new generation of Long March carrier rockets into China’s aerospace arena.
The birth of the “Long March 6” is of groundbreaking significance. Its first stage is equipped with a YF-100 liquid oxygen-kerosene engine, and its second stage is equipped with a YF-115 liquid oxygen-kerosene engine. These are the main power configurations of the new generation of “Long March” rockets. The first flight of the “Long March 6” is also the first flight of these engines. At the same time, the “Long March 6” has also created many international firsts. For the first time in the world, the self-generated supercharging technology of the oxygen tank of the high-pressure regenerative liquid oxygen-kerosene engine was proposed, which solved the internal supercharging of the engine oxygen tank; for the first time in the world, the high-power servo mechanism control technology of direct drainage of high-pressure kerosene was proposed, which solved the problem of large center of mass deflection of the engine; for the first time in the world, the 200K (200 degrees Celsius) large temperature difference foam sandwich common bottom tank technology was proposed, which solved the effective insulation and load-bearing of the liquid oxygen-kerosene propellant tank.
This launch mission is the 12th launch mission of the Long March 6 carrier rocket, the 217th launch of the Long March series of carrier rockets developed by Shanghai Aerospace, and the 534th launch of China’s Long March series of carrier rockets.
