The embodiment of the invention provides a multi-star distributor force bearing structure which comprises a force bearing cylinder with a grid structure. The grid structure is a skin-free grid structure. A first inner reinforced n-shaped frame is arranged at a first end of the force bearing cylinder, and a second inner reinforced n-shaped frame is arranged at a second end of the force bearing cylinder; and at least one first satellite supporting table is arranged on an outer side arc surface of the first end of the force bearing cylinder, and at least one second satellite supporting table is arranged on the outer side arc surface of the second end of the force bearing cylinder. According to the scheme, use requirements of carrying and releasing a plurality of satellites at the same time can be met, rigidity is high, weight is light, the structure is integrally manufactured, assembly is simple, reliability is high, manufacturability is good, and product consistency is good too.
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...
