Abstract
The invention relates to a downward pull type unfolding and shaping mechanism for the reflecting surface of an inflatable unfolding type parabolic cylinder antenna, and belongs to the technical field of spaceborne antennae. The problem that due to a shaping device adopted for the reflecting surface of an existing inflatable unfolding type parabolic cylinder antenna, the overall weight of the antenna is large is solved. The unfolding and shaping mechanism comprises the flexible reflecting surface, carbon fiber side plates, aramid fiber cloth, inflatable unfolding and supporting rings, air pipes and carbon fiber supporting rods. The left sides and the right sides of the upper surface and the lower surface of the flexible reflecting surface are respectively provided with one carbon fiber side plate; the lower sides of the two carbon fiber side plates located on the lower surface of the flexible reflecting surface are respectively provided with one piece of aramid fiber cloth, the upper edge of each piece of aramid fiber pull cloth is in a parabolic shape, the left side and the right side of each piece of aramid fiber pull cloth are respectively provided with the arc-shaped inflatable unfolding and supporting rings, and the inflatable unfolding and supporting rings located on the left side and the right side of each piece of aramid fiber pull cloth are sequentially communicated end to end through the air pipes; the two carbon fiber side plates located on the upper surface of the flexible reflecting surface are connected through the carbon fiber supporting rods. The downward pull type unfolding and shaping mechanism is used for shaping the flexible reflecting surface.
Description
Technical field
The invention belongs to satellite antenna technical field, the reflecting surface pull-down that is specifically related to a kind of inflating expanded parabolic-cylinder antenna launches shaping mechanism.
Background technology
The reflecting surface of inflating expanded parabolic-cylinder antenna is to adopt flexible material, can curlingly fold, volume after folding is little, be convenient to delivery, inflating expanded with gas-filled tube during use, by shaping device solid shape, form parabolic shape, the shaping device that the reflecting surface of current gas-filled unfolded parabolic-cylinder antenna adopts all comprises the heavier structures such as metal, causes antenna overall weight large, has increased delivery burden.
Summary of the invention
The object of the invention is to cause in order to solve the shaping device of the reflecting surface employing of current gas-filled unfolded parabolic-cylinder antenna the problem that antenna overall weight is large, provide a kind of reflecting surface pull-down of inflating expanded parabolic-cylinder antenna to launch shaping mechanism, its technical scheme is as follows:
The reflecting surface pull-down of inflating expanded parabolic-cylinder antenna launches a shaping mechanism, and it comprises flexible reflecting surface, carbon fiber side plate, aramid fiber granny rag, inflating expanded support ring, tracheae and carbon fiber support bar, the upper surface of flexible reflecting surface and lower surface a carbon fiber side plate is each side set, carbon fiber side plate and flexible reflecting surface are bonding, at two carbon fiber side plate downsides that are positioned at flexible reflecting surface lower surface, an aramid fiber granny rag is respectively set, the top edge of aramid fiber granny rag is parabolic shape, the top edge of aramid fiber granny rag is bonding with corresponding carbon fiber side plate, at every aramid fiber granny rag the inflating expanded support ring of a plurality of arcs is each side set, a plurality of inflating expanded support ring of the every aramid fiber granny rag left and right sides is crisscross arranged, the two ends of each inflating expanded support ring are bonding with corresponding carbon fiber side plate, side and aramid fiber granny rag that each inflating expanded support ring is relative with aramid fiber granny rag are bonding, a plurality of inflating expanded support ring that is positioned at the every aramid fiber granny rag left and right sides is communicated with head and the tail successively by tracheae, between two blocks of carbon fiber side plates of flexible reflecting surface upper surface, by many carbon fiber support bars, connect.
Beneficial effect of the present invention is: utilize aramid fiber granny rag and the inflating expanded support ring flexible reflecting surface that formalizes, setting accurately, lightweight, can curlingly fold, and volume after folding is less, the delivery of being more convenient for.
accompanying drawing explanation:
