Description
Technical Field
The invention relates to the technical field of space remote sensing, in particular to a center-supported carbon fiber multifunctional remote sensing camera.
Background
The carbon fiber first reflector has high specific rigidity and excellent thermal performance and dynamic performance. Therefore, the honeycomb type optical remote sensing camera can be made into a honeycomb type hollow structure and can also be made into a thin-wall type structure, and the requirements of the ground and the space optical remote sensing camera on light weight can be met. In recent years, carbon fiber primary reflectors have become popular for use in the international field of optical remote sensing.
In the prior art, most of the carbon fiber first reflectors are thin-walled structures. In order to ensure the integral supporting rigidity and stability of the camera, the supporting mode adopted between the main mirror and the second reflecting mirror is mainly in a triangular pyramid bracket form. The top end and the bottom surface of the triangular pyramid support are respectively connected with the second reflecting mirror and the substrate of the camera. In order to ensure the support rigidity, the bar members of the triangular pyramid-shaped support cannot be made long, and therefore, the radial dimension of the base plate is large. This will certainly increase the overall weight of the camera. Therefore, in order to realize an ultra-lightweight design, a new support method needs to be designed.
