Abstract

The invention discloses a sliding unfolding system suitable for a large space fixed-surface antenna. The sliding unfolding system comprises a fixed-surface antenna, a drive sliding system, unlocking devices and locking mechanisms, wherein the fixed-surface antenna is a plane or a cylindrical paraboloid after being unfolded and is formed by stacking a plurality of equant panels; the drive sliding system comprises a motor, a steel wire rope, a rope winding drum, fixed pulleys, idler wheels and transition blocks; the unlocking devices include interlayer unlocking devices, the transition blocks and interplate unlocking devices; the locking mechanisms are interplate locking mechanisms; various panels are unfolded and then connected through the interplate locking mechanisms; the rope winding drum is arranged at one end of the lowest panel; the motor drives the rope winding drum to rotate; and the rope winding drum, the steel wire rope and the fixed pulleys form a series drive system. The fixed-surface antenna is sequentially deployed by adopting a series order; a traditional hinged unfolding mode is broken; the closing space is reduced to adapt to carrying enveloping; and the sliding unfolding system has the characteristics of being small in overall envelope, few in drive sources, small in locking impact and high in locking rigidity.

Description

technical field

[0001] The present invention relates to the technical field of deployment methods for large space solid surface antennas, in particular to a sliding type deployment method and system suitable for large space solid surface antennas. Background technique

[0002] Among the existing space antennas, the flexible thin film antenna has a high storage ratio, but its shape and surface accuracy is low; the solid surface antenna has a high shape and surface accuracy, but it is difficult to store and unfold. For the requirement of high-resolution microwave detection, large solid-surface antenna has become the only choice. If the original hinge unfolding method is adopted, the envelope in the folded state will exceed the limit of the carrying envelope, especially for cylindrical parabolic antennas, so it is urgent to solve its storage. and expand the question. Contents of the invention

[0003] In view of the above technical problems, the present invention provides a ...
