Cross layout antenna deployment device applied to spacecraft

Abstract

The invention discloses a cross-layout antenna deployment device applied to a spacecraft, which includes a root hinge, Main extension arm one, Hinge between poles one, Main extension arm number two, hinge between two rods, Main extension arm number three, 4 antennas, 45 deg. Deployment hinge, 135 deg. Deployment hinge, two inn antenna mounting arm, two outer antenna mounting arms, a main extensionarm pressure release device, an antenna mount arm pressure release device, an antenna bundle unlocking device, an antenna deployment hinge and an antenna support, the inner antenna mounting arm beingconnected with an X-shaped joint through the 45 deg. Deployment hinge; The outer antenna mounting arm is connected with an X-shaped joint through a 135-degree deployment hinge. The invention can effectively fold the four cross-layout antennas to a smaller envelope, reasonably arrange the pressing points, so that the folded state not only meets the requirements of the rocket envelope, but also meets the requirements of the mechanical conditions of the active section. After entering orbit, the antenna can be unlocked and deployed to the specified position according to the remote control commandand meet the requirements of antenna cross layout.

Description

technical field [0001] The invention relates to the field of spacecraft accessories, in particular to a cross layout antenna deployment device applied to spacecraft. Background technique [0002] With the development of aerospace technology, the spacecraft has higher and higher requirements for the antenna load capacity, and the antenna load usually needs to work through multiple antenna arrays to meet the performance requirements. And many antennas need to be extended to a position away from the spacecraft body to avoid electromagnetic interference of the spacecraft body or interference with other spacecraft loads. The traditional antenna deployment device mainly uses one antenna to configure one deployment device. If multiple antennas are arrayed, multiple deployment devices are required. Although the structure is simple, the overall weight of the system is heavy, and the limited load mounting area on the surface of the spacecraft is occupied. Especially for tiny spacecra...

Problems solved by technology

The traditional antenna deployment device mainly uses one antenna to configure one deployment device. If multiple antennas are arrayed, multiple deployment devices are required. Although the structure is simple, the overall weight of the system is heavy and occupies a limited load mounting area on the surface of the spacecraft.

Especially for tiny spacecraft, there are strict restrictions on the weight and outer envelope of the spacecraft
