Cubesat multi-star orbital release device

Abstract

The invention discloses a cubesat multi-star orbital release device. The cubesat multi-star orbital release device comprises a machine box shell assembly, a cabin door assembly, a cabin door unlockingassembly, a mounting boss, a limiting unlocking assembly, a main spring out-pushing assembly, a spring plunger, a cabin door and a guiding rail, and the machine box shell assembly, the cabin door assembly, the cabin door unlocking assembly, the mounting boss, the limiting unlocking assembly, the main spring out-pushing assembly, the spring plunger, the cabin door and the guiding rail are connected with each other; the limiting unlocking assembly comprises a limiting unlocking assembly a and a limiting unlocking assembly b; the machine box shell assembly is a main body frame of the whole machine and provided with the guiding rail; when electromagnet of the limiting unlocking assembly is energized, the center shaft of the electromagnet is pulled back, an H-shaped limiting rod moves upwardsunder the action of a pulling spring, the limiting state of a satellite is relieved, and the satellite is ejected out; and the cabin door presses cubesats in the machine box shell body when closed, and when unlocking, a certain angle degree is opened and then locked under the action of a torsional spring. According to the cubesat multi-star orbital release device, the technical problem that in theprior art time-sharing and multi-angle cannot be conducted, and the cubesats cannot be released one by one in the releasing process is solved, time-shearing releasing ejecting of the multiple cubesats can be achieved, and networking work of the cubesats is facilitated.

Description

technical field [0001] The invention relates to the fields of aerospace, aircraft unlocking and release, and precision machinery, in particular to a cube star multi-satellite orbit release device. Background technique [0002] The cube star standard was first proposed by Caltech and Stanford University in 1998, and the first cube star was launched in 2003. CubeSat has the advantages of high standardization, short development period, and low development cost. With the rise of commercial spaceflight, the development of CubeSat has developed rapidly, accounting for more than 60% of the number of commercial spaceflight launches. [0003] CubeSat launches must use a special track release device. The invention provides a CubeSat multi-satellite ejection mechanism, which can load multiple CubeSats at the same time, and can realize the time-sharing ejection of each CubeSat, which can greatly reduce the launch of the CubeSat. costs, and can provide support for CubeSat on-orbit multi...

AI Technical Summary

Problems solved by technology

However, in the existing technology, there are technical problems that the cubesats cannot be released from multiple angles in time-sharing and cannot be released one by one during the release process.
