Grade 4 solid carrier rocket Jielong No. 3 transfer to the first flight test stage

On the 11th, the reporter learned from the First Hospital of China Aerospace Science and Technology Group that China Long March Rockets Co., Ltd., which belongs to the first house of China Aerospace Science and Technology Group, has successfully completed the static static and separation test of the rectifier and separation test. The cover design scheme, process plan, quality reliability, maximum available envelope, etc. are fully verified, marking the successful ending of the large ground test during the Jielong III rocket engineering stage, which is fully transferred 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.

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.
