In response to the launch mission requirements of “one arrow with 41 satellites”, the Changerding rocket development team took a series of effective measures to ensure the safe and accurate orbiting of 41 satellites by rationally arranging in the limited fairing space and selecting the optimal separation scheme. .
[Chang Zheng – Long March 2D yao 88 /Jilin-1 “One Carrier Rocket 41 Satellites” adopts the satellite layout of wall-mounted*38+sidewall*3】
One arrow launches 41 satellites, setting a new record for the largest number of satellites launched in one time in my country. But to safely and smoothly send so many satellites into orbit at one time, the first thing to solve is the layout of the satellites in the fairing, not only to ensure “sit down”, but also “sit comfortably”. To this end, the development team of Eight Director Erding fully sorted out the structure and mission requirements of the satellites, fully tapped the potential, optimized the layout design, adopted the layout method of 38 satellites on the wall + 3 satellites on the side wall, and successfully found 41 satellites. Safe and comfortable location.
In order to allow 41 ” satellite passengers” to enjoy a comfortable flight experience, the model team effectively used the space in the fairing to move the “feet” of the “passengers” under the adapter, and opened up 3 “special seats” on the support cabin , Successfully let 41 satellites “board” smoothly. Although the form of the “seat” is relatively new, but a closer look shows that they are all high-quality parts that have been sent to the “passengers” before, which effectively guarantees the safety and reliability of this mission.
In addition, in order to avoid crowded collisions when “getting off the car”, the research and development team of the Eighth Academy ingeniously designed the “drop-off plan” to allow the satellites to separate in an orderly manner. The overall design team divided the 38 satellites on the cylindrical multi-satellite adapter into one group of “passengers” on each floor, a total of 6 groups; the 3 “passengers” on the lower support cabin were taken as the seventh group, and the satellites were carried out in sequence according to the group separate. In addition, this rocket is also equipped with 10 reverse thrust rockets. By turning on the reverse thrust rockets, the distance between each group of satellites is widened to ensure the safety of separation from each other
