An embodiment of the present invention provides a load-bearing structure of a multi-star distributor, including: a load-bearing cylinder with a grid structure, and the grid structure is a grid structure without skin; the first end of the load-bearing cylinder A first inner reinforced frame is provided, and a second inner reinforced frame is provided at the second end of the load-bearing cylinder; at least one first As for the satellite supporting platform, at least one second satellite supporting platform is arranged on the outer circular arc surface of the second end of the bearing cylinder. The solution of the present invention can realize the use requirements of carrying and releasing multiple satellites at the same time, and has high rigidity, light weight, structurally integrated manufacturing, simple assembly, high reliability, good manufacturability, and good product consistency.
Description
technical field [0001] The invention relates to the technical field of aircraft, in particular to a load-bearing structure of a multi-satellite distributor. Background technique [0002] The load-bearing cylinder of the multi-satellite distributor is mainly used for launching multiple satellites with one arrow. The load-bearing cylinder of the multi-satellite distributor can generally arrange 2 or 4 satellites according to its own ring direction, and the connection point is generally located in the load-bearing cylinder of the multi-satellite distributor. Each satellite is generally connected to the load-bearing cylinder of the multi-satellite distributor through four connection points, and the four points also have the functions of separation and pop-up release. The weight efficiency of the load-bearing cylinder of the multi-satellite distributor is exactly the same as that of the satellite. At the same time, the load-bearing cylinder must also meet the overall stiffness re...
