Description
Technical field
The invention belongs to space based radar technical fields, and in particular to a kind of radar antenna reflecting surface and bistable state composite material
The connection method of telescopic column shell.
Background technique
Space based radar can all weather operations, have a wide range of, high-precision detectivity, have optical system, ground
The ability that radar and airborne radar do not have；Due to many merits of space based radar, thus receive the extensive weight of numerous countries
Depending on research；For length direction up to hundred meters, the massive phased array flat plane antenna that area reaches hundreds of square metres is the important of space based radar
The area of component part, antenna is big, and length-width ratio is high, and for the ease of delivery, antenna must be crimped on ground and be folded, and is emitted to space
Reinflated work afterwards, existing foldable deployable antenna mainly have mechanical and two kinds of support expansion modes of inflatable, mechanically
Structure is complicated, and weight is larger, and being affected by temperature due to gas for inflatable is expanded with heat and contract with cold obvious, rear stability is unfolded
Undesirable, so having developed a kind of reflecting surface supported by bistable state composite material telescopic column shell, bistable state composite material can
Folding exhibition column shell is the cylindrical shell structure of C-shaped cross-section, using the elastic telescopic composite material such as carbon fiber, with rigid support
Ability, and can fold delivery with reflecting surface along axial convolution, but existing connection method be not suitable for by reflecting surface with
The connection of bistable state composite material telescopic column shell hinders bistable state composite material telescopic column shell along axial convolution, makes after connection
Folded volume increases, so proposing this programme.
Summary of the invention
The purpose of the present invention is to solve the above problems existing for existing foldable deployable antenna, provide a kind of thunder
Up to the connection method of antenna reflective face and bistable state composite material telescopic column shell, its technical solution is as follows:
A kind of connection method of radar antenna reflecting surface and bistable state composite material telescopic column shell, it includes to use aramid fiber
Space based radar antenna reflective face is connect by rope and aramid fabric with bistable state composite material telescopic column shell, and muti-piece is arranged along aramid fiber rope
Aramid fabric, aramid fabric are arranged at intervals on the opposite sides of aramid fiber rope, and the midline position of aramid fabric is aligned with aramid fiber rope, aramid fabric with
The suture of aramid fiber rope is connected and is bonded, and the total quantity of aramid fabric is odd number block, and wherein the aramid fabric of odd number is Nian Jie with reflecting surface, wherein
The aramid fabric of even number is Nian Jie with bistable state composite material telescopic column shell, aramid fiber rope be arranged in odd number aramid fabric and reflecting surface it
Between, while aramid fiber rope is also disposed between the aramid fabric of even number and bistable state composite material telescopic column shell.
The invention has the benefit that being not only connected firmly, and bistable state composite material telescopic column shell energy after connection
Along axial direction with the smooth convolution of reflecting surface, reduce volume after folding, convenient for delivery.
Detailed description of the invention:
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is Fig. 1 decomposition diagram；
Fig. 3 is the positional diagram of odd, even several aramid fabrics and aramid fiber rope；
Fig. 4 is the convolution schematic diagram of bistable state composite material telescopic column shell.
Specific embodiment:
Referring to figs. 1 to Fig. 4, a kind of connection method of radar antenna reflecting surface and bistable state composite material telescopic column shell,
It includes to be connected space based radar antenna reflective face 3 and bistable state composite material telescopic column shell 4 using aramid fiber rope 1 and aramid fabric 2

Position is aligned with aramid fiber rope 1, and aramid fabric 2 and aramid fiber rope 1 suture connection and be bonded, and the total quantity of aramid fabric 2 is odd number block, wherein
The aramid fabric 2 of odd number is Nian Jie with reflecting surface 3, and wherein the aramid fabric 2 of even number is Nian Jie with bistable state composite material telescopic column shell 4,
Aramid fiber rope 1 is arranged between the aramid fabric 2 of odd number and reflecting surface 3, and aramid fiber rope 1 is also disposed at the aramid fabric 2 and bistable state of even number
Between composite material telescopic column shell 4.
