Jielong III Rockets completed the engineering stage large -scale ground test transfer to the first flight test stage

Xinhua News Agency, Beijing, August 11th (Reporter Hu Yan) On the 11th, reporters learned from the First Hospital of China Aerospace Science and Technology Group that China Long March Rocket Co., Ltd., which belongs to the first house of China Aerospace Science and Technology Group, seized the 4 -level solid carrier rocket Jielong San The number of static static and separation tests was successfully completed. The rocket rectification design scheme, process plan, quality reliability, maximum available envelope, etc. were fully verified, marking the successful ending of the large ground test of the Jielong III rocket engineering stage, comprehensive comprehensive, comprehensive Transfer to the first flight test stage.

In the process of rockets into space, the rectifier cover is like armor, protecting effective loads such as satellites, and exempting the effects of extreme environmental conditions such as heat, wet, sound, and vibration. Guarantee safety and comfortable.

It is reported that Jielong 3 rectifier is the largest rectifier cover used by domestic solid rockets, and it is also a new challenge for the development team. The static static test of the rectification cover is mainly used to verify the structural strength and rigidity of the rectifier, the correctness of the design scheme, and the reliability of the materials, size, and connection methods of the main bearing component. Calculation computing model, etc. The splitting test of the rectification cover has verified the adaptability of the maximum packaging of the rectifier to the satellite, and determined the maximum available package of the rectifier.

Gao Lijun, the person in charge of the Jielong III rockets, introduced that in order to ensure that the satellite protection was in place during the docking of the Star Arrow, the team carried out the maximum package of the collision danger of the simulation satellite in the rectified cover test. In the design, the environmental guarantee of the satellite is fully considered. All the separation devices use the long -term series of carrier rockets used by the Long March series of mature products, which will not affect the satellite in the separation unlocking process. In the future, the development team will also complete the full arrow's zero -second simulation state test, factory test, rocket and launch base practice.

The "Jielong" series of rockets is a series of solid carrier rocket launched by China Long March Rocket Co., Ltd. for the commercial aerospace launch market. Jielong III Rockets completed the item by the end of 2020. It is the one -type rocket with the largest diameter, the strongest inload capacity, and the largest rectification bag space in the "Jielong" series of rockets. Multi -star launch capabilities have the characteristics of high cost performance, strong adaptability, and short performance cycle.
