Description
Technical field:
The invention belongs to radial rib antenna technical field, be specifically related to a kind of band film radial rib of deployable antenna.
Background technology:
The floor of radial rib inflatable space antenna plays the effect guaranteeing reflector precision, and existing floor entirety adopts carbon fiber board to make, and weight is large, and is not easy to draw in folding.
Summary of the invention:
The object of the invention is to adopt carbon fiber board to make to solve existing floor entirety, weight is large, and is not easy to draw folding problem in, and provide a kind of band film radial rib of deployable antenna, its technical scheme is as follows:
A kind of band film radial rib of deployable antenna, it comprises carbon fiber board and the sub-film of double-deck polyamides, described carbon fiber board and the sub-film fixed bonding of double-deck polyamides, carbon fiber board aligns with the lower limb of the sub-film of double-deck polyamides, the abutted surface integrated bond of carbon fiber board and the sub-film of double-deck polyamides, multiple triangle fin keel is provided with on the upside of carbon fiber board, and each triangle fin keel place is provided with suspension cable hole, the sub-film of double-deck polyamides is provided with multiple suspension cable hole along top edge, around the multiple suspension cable holes on the sub-film of double-deck polyamides, is provided with strengthening membrane.
Beneficial effect of the present invention is: change the structure that existing floor entirety adopts carbon fiber board, the sub-film of double-deck polyamides is used to replace part carbon fiber board, weight is obviously reduced, and it is folding to be easy to gathering, volume after folding is little, on the sub-film of double-deck polyamides with on triangle fin keel, be provided with suspension cable hole, after using hoist cable to be connected with mast, floor precision and stability can be ensured.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Embodiment:
With reference to Fig. 1, a kind of band film radial rib of deployable antenna, it comprises carbon fiber board 1 and the sub-film 2 of double-deck polyamides, described carbon fiber board 1 film 2 fixed bonding sub-to double-deck polyamides, carbon fiber board 1 aligns with the lower limb of the sub-film 2 of double-deck polyamides, the abutted surface integrated bond of carbon fiber board 1 and the sub-film 2 of double-deck polyamides, multiple triangle fin keel 1-1 is provided with on the upside of carbon fiber board 1, and each triangle fin keel 1-1 place is provided with suspension cable hole 3, the sub-film 2 of double-deck polyamides is provided with multiple suspension cable hole 3 along top edge, strengthening membrane 3-1 is provided with around multiple suspension cable holes 3 on the sub-film 2 of double-deck polyamides.
The using method of invention and principle: head and the tail two ends are bonding with central dram axostylus axostyle and crisp bar by materials such as aramid fabric, the part of carbon fiber board 1 by aramid fabric to refer to that slotting mode is bonding with central dram axostylus axostyle and crisp bar, and be connected with crisp bar by hoist cable at suspension cable hole 3 place, primary load bearing hoist cable is connected with the suspension cable hole 3 on carbon fiber board 1, is connected from the suspension cable hole 3 the sub-film 2 of messenger wire and double-deck polyamides; It is high that the sub-film 2 of double-deck polyamides has hot strength, not easily plastic deformation occurs, and high temperature resistant, radiation hardness, resistance to chemical attack and electrical insulation capability are high, and lightweight, alleviate floor weight greatly, is also easy to draw in folding.Mast, as a kind of force transferring part, can provide uniform radially expanding force, and this radially expanding force can guarantee precision and the stability of this band film rib.
