Separate-orbit CubeSat launching device

Abstract

The invention discloses a separate-orbit CubeSat launching device for carrying or launching a single or a plurality of standard CubeSat. The separate-orbit CubeSat launching device mainly comprises a rectangular framework, an unlocking mechanism and a spring mechanism, wherein the rectangular framework is mainly constructed by connecting a cabin door, a baffle plate, bottom plates, side plates, upper cover plates and a back cover plate in a threaded way; a separate guide rail is arranged as a satellite slide rail; a rotary electromagnet and the like are taken as the unlocking mechanism; the spring mechanism comprises a push plate and pressure springs. The separate-orbit CubeSat launching device has high generality, and is low in cost; the transportation safety and launching reliability of satellites can be ensured, displacement of the satellites during transportation can be prevented, and the cabin door is not collided with a running platform or reversed in an opening process; moreover, a push plate anti-separation measure and the like are adopted.

Description

technical field [0001] The invention belongs to the technical field of standard cubesat carrying and launching, in particular to a separate orbit type cubesat launching device. Background technique [0002] With the development of microelectronics technology, new materials, new energy and other technologies, the application of microsatellites has developed rapidly. At present, they are mainly used for communication, remote sensing of the earth, interplanetary exploration, scientific research and technical experiments, etc., and also have military applications. Wide application prospects, so many countries have included it in the national research plan, as a commanding height of technology and economic development in the 21st century. my country Aerospace Dongfanghong Satellite Company, Shanghai Microsatellite Engineering Center of the Chinese Academy of Sciences, National University of Defense Technology, Tsinghua University, Harbin Institute of Technology, Zhejiang Universi...

AI Technical Summary

Problems solved by technology

[0005] (1) Cost problem: the structure is exquisite and complex, and the processing cost and processing accuracy are high;

[0006] (2) The problem of hatch rotation: when the unlocking device is unlocked, the hatch opens and may rotate excessively, colliding with the carrying platform, causing unnecessary damage;

[0007] (3) Anti-restoration of the cabin door: During the release process of the microsatellite, if the cabin door recovers during the rotation process, it will affect the release of the microsatellite, and may even cause damage to the microsatellite;

[0008] (4) The problem of push plate coming out: the push plate is between the spring and the micro-satellite, and the small satellite is pushed out of the release device by using the energy in the spring. When the small satellite is completely released, the push plate may come out of the release device under the action of inertia;

[0009] (5) Applicability issues: the current satellite release device is not very versatile, and it is only suitable for small satellites that are square and without any additional devices

[0010] (6) The problem of the degree of freedom of the micro-satellite: During the launch process of the launch vehicle, the stress environment is relatively complicated. If the micro-satellite has no degree of freedom restriction measures, it will run around in the launch device, which may cause damage to the device and the small satellite.
