Deformable 12U cubesat platform

Abstract

The invention relates to a deformable 12U cubesat platform which comprises a 3U cubesat platform A, a 3U cubesat platform B, a 3U cubesat platform C and a 3U cubesat platform D. A rotating mechanism A and a locking mechanism I are mounted at the joint of the 3U cubesat platform A and the 3U cubesat platform D; a rotating mechanism B and a locking mechanism II are mounted at the joint of the 3U CubeSat platform B and the 3U CubeSat platform B; the 3U CubeSat platform A and the 3U CubeSat platform B are provided with a rotating mechanism C and a locking mechanism III; a fusing line device A is arranged on the bottom surface of the 3U cubesat platform B; and a fusing line device B is arranged on the bottom surface of the 3U cubesat platform D. The launching deployment state is a 4 * 3U cube state, the launching deployment state is a 2 * 6U cube state through first deformation, the launching deployment state is a 1 * 12U cubesat platform through second deformation, platform deformation is achieved through the minimum number of deformation times and a simple mode, and platform deformation can be completed on the premise that the minimum cubesat internal space is occupied under the limitation of the cubesat size.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a deformable 12U cubic star platform. Background technique [0002] CubeSat is a low-cost microsatellite that adopts international general standards. 1U (Unit) cube star, the volume is 10cm×10cm×10cm; on this basis, it can be expanded to “2U”, “3U” or even “12U” (20 cm×20 cm×30cm). A common 12U cube star is usually a 4×3U cube stack shape. [0003] However, this shape is too short for satellite platform observation baselines for many space optics projects that require long baseline platforms. In order to meet the platform baseline length requirements, a 1×12U cube platform can be used. However, using a 1×12U cube platform directly will bring many problems such as mechanical properties and carrying convenience during launch and deployment, and the achievability is too low. Therefore, a larger volume of CubeSats has to be used, but it also loses the advantages of small size a...
