Embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
The present embodiment provides a kind of gas support that can be used for Bearing cylinder formula satellite, to solve to be currently used in center
The gas cylinder supporting construction of load cartridge type satellite can not meet gas cylinder centralized arrangement, integral disassembly, assembly, improve space availability ratio, reduce cloth
The shortcomings that situation is accumulated.
The gas support includes one piece of gas cylinder installing plate 1 and three pieces of supporting plates 2, the gas cylinder installing plate 1 and supporting plate 2
Using carbon fiber skin aluminum honeycomb compound material, (carbon fiber skin is connected with honeycomb core by glued membrane, pre- in honeycomb core
Put aluminium alloy embedded part, whole plate curing molding in autoclave.Before compound, chemical composition reinspection and nondestructiving inspecting test are carried out,
To meet the requirement of space-age material).Gas cylinder installing plate 1 is installed first on Bearing cylinder 3, ensures gas cylinder peace during installation
The height in dress face and the depth of parallelism requirement with satellite benchmark.Due to the side end face of gas cylinder installing plate 1 one and the Bearing cylinder 3
Fitting, therefore the arcuate structure that the side of gas cylinder installing plate 1 is designed as matching with the excircle of Bearing cylinder 3.In gas
The upper surface of bottle installing plate 1 is evenly distributed with three gas cylinder mounting interfaces along its circumference, as shown in Figure 1.
In each gas cylinder mounting interface, five tie points are radially distributed with along gas cylinder installing plate 1, due to apart from supporting plate
