China News Service Yellow Sea ro-ro passenger ship “Zhonghua Fuxing”, September 15 (Guo Chaokai, Wang Weitong, Gao Chongrui) At 09:23 on September 15 Beijing time, was developed by the Academy of China Launch Vehicle Technology under the China Aerospace Science and Technology Corporation. The Long March 11 carrier rocket (Chang 11 rocket) used the “one arrow and nine stars” method in the Yellow Sea to successfully deliver the high-scoring group 03 “Jilin No. 1” satellites developed by Jilin Changguang Satellite Co ., Ltd. at 535 km Synchronous Orbit of the Sun.
The 03 high-scoring “Jilin No. 1” satellites launched this time include 3 high-scoring 03C video satellites and 6 high-scoring 03B push broom satellites. This group of satellites will network with the orbiting “Jilin No. 1” satellite to provide users in forestry, agriculture, rangelands, oceans, resources, environment and other industries with richer remote sensing products and data.
Jin Xin, deputy commander-in-chief of the Long March 11 launch vehicle of the China Academy of Launch Vehicle Technology, stated that the mission is 10 consecutive high-precision orbits of the Long 11 rocket, 10 consecutive zero-mass problems in the rocket and 10 consecutive point launches of zero window. It is the second maritime launch mission carried out by the Chang-11 rocket and also the first launch of a commercial maritime application.
“This launch mission is a real maritime commercial application launch. It not only sent the nine Jilin-1 High-Fund 03 satellites developed by Jilin Changguang Satellite Co., Ltd. into the synchronous orbit of the sun at the same time, and they completed the same orbit. The deployment of sea launch technology, and further optimize the sea launch technology process, improve the safety and reliability of sea launch technology, and lay the foundation for the standardization and high frequency of sea launch in the future, “said Jin Xin.
How is this launch mission different from China’s first sea launch? Peng Kunya, chief designer of the Long March 11 carrier rocket at the Chinese Academy of Launch Vehicle Technology, said that the rocket for this mission was completed directly at the Eastern Spaceport after the rocket docking and rocket assembly test. stellar. Haiyang port was transported to the Yellow Sea scheduled maritime area for launch, completely breaking the previous pattern of separation of rocket production and launch site, reducing the number of disassembly and assembly and transport link long-distance railway, and carried out the integration of rocket assembly test and launch for the first time, greatly shortening launch chain to improve launch efficiency and benefit.
This is also the first time that the Chang-11 rocket has launched a synchronous orbit to the sun at sea. “The launch direction of the sun-synchronous orbit is fixed. Once the launch area and launch point selected for the maritime launch are verified, they can be solidified in the future. At the same time, the launch tasks of synchronous orbit with the sun are more frequent and the choice of debris landing areas for land launch becomes increasingly difficult. Successful sea launch implementation will further highlight the advantage of greater orbital adaptability, “said Peng. Kunya.
Since its maiden flight, the Chang-11 rocket has successfully achieved 8 consecutive land launches and 2 marine launches. He has achieved ten battles and ten victories, demonstrating the high reliability and flexibility of the “Quick Sound Arrow” in commercial launches. Various launch capabilities.
“At present, the Chang-11 rocket development team is developing a robust carrier rocket with a faster response, increased market competitiveness and a low-orbit payload capacity covering 2 tons. It is planned to use the method. launch to conduct the first extremely low-tilt orbit launch test in 2022. It will form a more comprehensive robust launch vehicle capability to meet the launch needs of different satellite users, ”said Li Tongyu, commander in chief of the Long March 11 launch vehicle of the Chinese Academy of Launch Vehicle Technology.
It is understood that the China Academy of Launch Vehicle Technology relies on China Long March Rocket Co., Ltd. to build a commercial aerospace platform and actively play the three functions of platform commercial operation, model innovation and capital operation. The long March 11 carrier rocket’s first maritime applications launch mission is At a new starting point, we will initially conduct standard commercial operation of launch vehicles at sea; We will coordinate with Yantai, Shandong to accelerate the construction of the major projects of the Eastern Aerospace Port, and will initially realize the new integrated solid carrier rocket assembly, test and launch capabilities, greatly shortening the space launch chain.
In the future, China Long March Rocket Co., Ltd. will actively promote the serial development of commercial launch vehicles such as Jielong series, build the best commercial launch vehicles in China, and endeavor to provide commercial satellite users with solutions. cost-effective combined launch launchers and increase China’s commercial aerospace efficiency. development of.
