Embodiment Construction

[0015] Preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0016] figure 1 It is the configuration in the stretched state of the folded and unfolded support tube of the space film facility of the present invention, such as figure 1 In the illustrated embodiment, the device includes:

[0017] The upper thin-walled shell 1 and the lower thin-walled shell 2 with a cross-section in the shape of "Ω", the semicircular concave surfaces in the middle of the upper thin-walled shell 1 and the lower thin-walled shell 2 are facing each other, and the planar edges on both sides correspond to each other Glue to form a pod-shaped thin-walled support pipe with a length of 0.5-30m.

[0018] The cross-sections of the upper thin-walled housing 1 and the lower thin-walled housing 2 can also be formed by tangential arcs of multiple segments, the edge of the thin-walled housing is planar, and the upper thin-walled housing 1 and t...

Abstract

The invention relates to aerospace vehicle equipment, and discloses a retractable and unfolded support tube for a space film facility, comprising: an upper thin-walled shell [1] and a lower thin-walled shell [2] with a cross-section in the shape of "Ω". The semicircular concave surfaces are opposite to each other, and the flat edges on both sides are glued to each other to form a pod-shaped thin-walled support tube. During the launch stage of the spacecraft, the thin-walled support tube is flattened into a flat strip and curled around itself or a drum. After the spacecraft is launched to the predetermined orbit, the thin-walled support tube unfolds and returns from the flat roll state to the long tube state. The above-mentioned upper thin-walled shell [1] and lower thin-walled shell [2] are prepared from high specific modulus fiber-reinforced resin matrix composite materials. The invention solves the problems of large volume, complex structure, low deployment stability and reliability of the original structure, and has the advantages of large elastic recovery force, high elastic recovery rate, good elastic recovery reliability, low density, high strength, high rigidity and low cost. inferior advantages.

Description

technical field [0001] The invention relates to airborne equipment of an aerospace vehicle, in particular to a retractable and unfolded support tube for a large-scale space film facility onboard an aerospace vehicle. Background technique [0002] With the surge of human demand for space resources, whether it is in the military field or in the commercial field, large-scale space film facilities onboard spacecraft, such as space antennas, solar arrays, solar sails, sun shields, space habitats and other large space films Facilities are being used more and more. However, these space film facilities are heavy in weight and large in storage volume, and are limited by the delivery vehicles, so their cost of construction and launch are very high. Therefore, the development of new large-scale expandable space film facilities is a hot topic at present. Especially the supporting structure of light weight, large size and good rigidity space membrane facilities is still difficult to so...
