Platform load cooperation system for ultra-large-aperture optical camera

Abstract

The invention provides a platform load cooperation system for an ultra-large-aperture optical camera. The system comprises a secondary mirror system and a primary mirror, wherein the secondary mirror system and the primary mirror are respectively disposed at the two sides of a platform, in case of an initial state, the secondary mirror system, the platform and the primary mirror are all at a completely furling state, and the secondary mirror system, a service chamber and the primary mirror are fixedly connected; and during extension, the primary mirror and the secondary mirror system are respectively pushed away from the service chamber towards a reverse direction by reliance on a furling truss structure and are locked once in place, the platform is extended to form three portions connected with one another, and after the primary mirror is completely extended, an optical path between the primary mirror and a secondary mirror passes through the inside of the extended service chamber so that it is ensured that the optical path is not shielded, the camera images normally, and the problem of the optical satellite configuration design of an ultra-large-aperture mirror surface is solved.

Description

technical field [0001] The invention relates to the field of aerospace, in particular to a collaborative design scheme for platform loads oriented to ultra-large aperture optical cameras. Background technique [0002] With the development of aerospace technology in recent decades, the structure of spacecraft tends to be more complex, its functions are more diverse, and its size and mass are also increasing. Due to the limitation of mass and envelope space, how to design a spacecraft with a reasonable configuration and performance under the relevant constraints is an important part of the development work. [0003] The space unfolding structure means that it is in a fully stowed state on the ground and is fixed in the payload compartment of the vehicle. After launching into orbit, it gradually completes the unfolding action according to the ground control instructions, and then locks and maintains it in a fully unfolded state. The unfolded structure greatly improves the carr...

AI Technical Summary

Problems solved by technology

If it is designed according to the traditional optical lens, it cannot satisfy the carrying envelope at all, and if the camera is installed on the side of the platform, there is also a contradiction between the rigidity and weight of the supporting structure, and it is difficult to guarantee the imaging accuracy
