Abstract

The invention provides a primary and secondary mirror telescopic system, comprising a primary mirror (1) that can be stretched and opened in the circumferential direction, a secondary mirror stretching arm (4) that can be stretched in the length direction, and a secondary mirror stretching arm (4) installed on the secondary mirror stretching arm (4) Secondary mirror (21) at the end. The invention solves the limitation of the size and weight of the satellite main reflector due to the carrying capacity of the existing rocket and the space size of the fairing through the innovative design of the main reflector of the satellite reflective optical imaging.

Description

A primary and secondary mirror telescopic system technical field The invention belongs to satellite technical field, be specifically related to a kind of primary and secondary mirror telescopic system, be used for satellite primary reflector and Telescopic control of the secondary mirror. Background technique Generally, the GEO reflective optical imaging satellite adopts an integral imaging system and a segmented unfolding imaging system. The stereo imaging system is limited by the space of the satellite fairing, which makes the main mirror of the integrated GEO reflective optical imaging satellite And can not be too large, which limits the imaging capability of the satellite. The rigid mirror imaging system of the block-deployed imaging system is mainly composed of glass It is composed of rigid materials such as glass and metal, which makes the overall mass of the satellite larger. Put forward high requirements for satellite vehicles, and On the one hand, the 3m...
