Abstract

The invention discloses a lunar-based expandable truss-type network cable reflection-surface antenna. The lunar-based expandable truss-type network cable reflection-surface antenna is characterized bycomprising an expandable truss-type support structure, a network cable reflection surface, a damping absorber and a traveling mechanism, wherein the network cable reflection surface is tensioned at the top of the expandable truss-type support structure, the damping absorber is fixed at a node of the bottom of the expandable truss-type support structure, and the travelling mechanism is fixed at the bottom of the damping absorber. The lunar-based expandable truss-type network cable reflection-surface antenna can be applied to actual engineering of high-accuracy and large-aperture reflection-surface antenna on a lunar surface and is suitable for a working condition of the lunar surface, the working performance requirement is met, and the lunar-based expandable truss-type network cable reflection-surface antenna has favorable storage ratio, integral stability and dynamic performance; and the lunar-based expandable truss-type network cable reflection-surface antenna is light in structure,simple in form, flexible in design and wide in application and has favorable military and civilian market prospect.

Description

technical field [0001] The invention belongs to the technical field related to aerospace vehicle structural engineering, in particular to a moon-based expandable truss-type cable-net reflector antenna. Background technique [0002] The current lunar-based antenna scheme is mainly based on dipole antennas. Due to its simple structure, it can indeed meet the requirements of miniaturization and light weight of spacecraft payloads. However, this type of antenna is always limited by its antenna form, and the antenna gain and ability to receive signals are limited. In contrast, the lunar-based reflector antenna, that is, a new concept of antenna with a directional aperture antenna set on the lunar surface, has better directivity, greater gain, and better signal sending and receiving performance. At the same time, the lunar-based reflector In addition to the above-mentioned advantages of the moon-based low-frequency antenna, the antenna is not subject to the shielding and attenuat...
