Long March family highest rocket!my country successfully launched the "Middle Star 1E" satellite

Changsha Evening News, Changsha, September 13th. According to the People's Daily Client News, Beijing time at 21:18 on September 13, 2022, my country uses the Long March VII Rockets at Wenchang Aerospace Launch September. Launching. The satellite enters the scheduled track smoothly, and the launch task has been successfully successful. The satellite is mainly used to provide users with high -quality voice, data, radio and television transmission services.

The task was the 437th flight of the Long March series of the Lange Rockets.

The March Family's highest rocket successfully launched

The China Lauding Rocket Technology Research Institute (hereinafter referred to as the "Rocket Institute"), which is affiliated to China Aerospace Technology Group Co., Ltd., has developed the long -seven -modified rocket developed by the total development of the new generation of medium -sized carrier rockets in my country. Based on the three -child of the Long March 3 -Lange Rockets, a high -orbit three -level liquid bundled carrier rocket formed by the combined design, the landing capacity of the Earth synchronous transfer orbit is not less than 7 tons, filling the synchronous transfer of the Lange Rocket Earth in my country The gap between the rail 5.5 to 7 tons of carrier capacity can be adapted with two rectifiers: 4.2 meters and 3.7 meters. It has one arrow and one star and one arrow double main star launch ability.

According to Wei Yuanming, the chief designer of the Long -Seven Rockets, the long seven -changes and five rockets of the long seven -changes and five rockets of this task uses a rectified cover of 4.2 meters in diameter. The whole arrow height is 60.1 meters. The rocket is consistent. As the first type of binding rockets that adopt the first type of booster and core clustering technology in my country, compared to the first -level ways to separate the aid machine and then separate the core, the rocket is bundled. The link structure is more simplified. At the same time, the beam separation also reduces a helper landing area. The entire combination is in a landing area, which is more conducive to controlling the rocket wreckage landing area.

This time is the fourth -time launching task of the rocket. The rocket status is gradually solidifying, and at the same time prepare for the high -density launch stage. Wei Yuanming introduced that the model team has made a number of optimization improvements on the design of the rocket technology. Under the premise of ensuring test coverage, through the optimization process order, parallel work, and combined testing, the launch technology process has been reduced from 32 days to 26 days. It has further improved rocket launch efficiency and laid the foundation for rockets to respond to high -density normal launch.

According to Deng Hongqin, director of the Xichang Satellite Launch Center, during the preparation of the long -seven modification launch mission, the star 1E satellite in Wenchang launches, the space station Mengtian experimental compartment, Tianzhou 5 freight ships at the same time, rockets, satellites, and spacecraft are all major models It is significant and responsible. The Xichang Satellite Launch Center puts aerospace launch and epidemic prevention and control integration, integrated organization, and integration. For the current high -density task characteristics of the launch site, carry out the long -term rockets to rectify the first liquid oxygen and oil in parallel to add the rocket to the launch of the rocket. The daily task process has shortened by nearly one -third, and continues to improve the ability to perform high -density space launch tasks.
