Abstract

The on-orbit assembly system for super-large space telescopes based on multi-space robots belongs to the technical field of spacecraft on-orbit services. The present invention solves the problem that existing launch vehicles have poor carrying and propulsion capabilities and cannot meet the requirements for carrying ultra-large-caliber space optical loads. , the three-mirror module in the assembly system of the present invention is located on the axis of the spacecraft platform, and the three-mirror module is fixedly connected to the top of the spacecraft platform, and the two solar wing sails are installed on the outer surface of the spacecraft platform at equal distances along the circumferential direction On the circular surface, the metering ring is set under the spacecraft platform, and one end of the metering ring is fixedly connected to the bottom of the spacecraft platform, the cargo cabin is set at the lower part of the metering ring, and the cargo cabin and the metering ring are disassembled and connected. On the metering ring, the telescopic robot arm is slidably connected to the metering ring through a sliding block, the telescopic robot arm can slide along the circumference of the metering ring, and the telescopic robot arm is used to grab parts in the cargo compartment.

Description

technical field [0001] The invention belongs to the technical field of on-orbit service of spacecraft, and in particular relates to an on-orbit assembly system of a super-large space telescope based on a multi-space robot. Background technique [0002] Space target surveillance, space situational awareness, and high-performance astronomical observation have strong demands for super-large-aperture optical payloads, and there is an urgent need to break through the development technology of super-large-aperture space optical payloads, laying a technical foundation for my country's development of the next generation of space surveillance and early warning systems and space astronomical telescopes . However, limited by the carrying and propulsion capabilities of launch vehicles, the existing launch vehicles cannot meet the carrying requirements of super-large-caliber space optical loads, which has led to bottlenecks in the development of the next-generation space surveillance and ...
