Abstract
An airborne antenna windward side security bar, comprises protective filmy layer, and the protecting film back side is for being non-drying glue layer 2, and protecting film edge is edge sealant or bonding agent; During use, the double faced adhesive tape at the protecting film back side is directly bonded to by protection coating, can be airborne antenna effective protection is provided; Have function admirable, cost low, make feature simple, easy to use.
Description
Technical field
The utility model belongs to airborne antenna technical field, is specifically related to a kind of airborne antenna windward side security bar.
Background technology
In the flight course of aircraft, because speed is fast, the windage that airborne antenna windward side is subject to is very large, especially when meeting sand dust weather, the high velocity air of dust-containing is easy to cause the destruction of antenna windward side, therefore, airborne antenna all requires to carry out dust and sand effect to verify the ability to bear of windward side to high speed sand dust.In actual applications, often occur that antenna is after the use of a period of time, windward side is fallen to paint the situations such as even badly damaged, must change.
At present, the main modes such as construction profile design, cover material and technological design, coating material and technological design that rely on of wind-proof sand dust design of airborne antenna realize, although can meet the requirement of relevant criterion by these modes, but relatively severe or work long hours in the situation that at environment, be difficult to guarantee the good protection of windward side.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model be to provide a kind of function admirable, cost low, make airborne antenna windward side security bar simple, easy to use, can be airborne antenna effective protection be provided.
To achieve these goals, the technical solution adopted in the utility model is: a kind of airborne antenna windward side security bar, comprise protective filmy layer, and the protecting film back side is for being non-drying glue layer, protecting film edge is edge sealant or epoxy adhesive.
Described protecting film can adopt polyester film or polyurethane film.
Described non-drying glue layer is double faced adhesive tape, can directly be bonded to by protection coating.
The cover antenna windward side of described protecting film, its length is determined according to the height of antenna windward side, and width exceeds windward side 10～50mm, and thickness is 0.2～1mm.
Described non-drying glue layer is consistent with protecting film shape, and thickness is no more than 0.2mm.
Described edge sealant or epoxy adhesive adopt aviation-grade product, with guaranteed performance.
Operation principle of the present utility model is:
During use, the double faced adhesive tape at protecting film 1 back side is directly bonded to by protection coating.
the beneficial effects of the utility model are:
Polyester film or polyurethane film have very strong adaptive capacity to environment, puncture-resistant, rub resistance, high temperature resistant and low temperature, can prevent the destruction to windward side such as air-flow, sand dust, film is that transparent material, quality are little, on the impact of antenna outward appearance, quality, can ignore, and antenna electric performance is had no effect.The double-sided tape of security bar reduces difficulty and the workload of installing greatly, and high-quality adhesive tape can guarantee bonding reliably, possesses extremely strong adaptive capacity to environment.Edge sealant can be avoided security bar edge, and because being subject to, the erosion of rainwater, sand dust is come unstuck, layering.
Actual application and environmental test result show, security bar of the present invention has stronger protective capacities and adaptive capacity to environment, can meet all kinds of environmental requirements of airborne equipment, use the airborne antenna of this security bar, when not installing 5 ~ 20 times of sand dust protective capacities.This security bar can be protected antenna windward side, prevents that antenna windward side is subject to the environmental injuries such as sand dust, hail, air-flow and rainwater, avoids occurring that windward side falls the phenomenons such as paint, burn into perforation.
Accompanying drawing explanation
Fig. 1 is the shape instance figure of protection film.
Fig. 2 is the sectional view of security bar.
Fig. 3 is the example that security bar is installed on antenna windward side.
Fig. 4 is for protecting the security bar instance graph on pinnacle, windward side, and wherein Fig. 4 (a) is security bar unfolding state figure; Fig. 4 (b) is attached to antenna surface state diagram for security bar.
Fig. 5 is for protecting the security bar instance graph of windward side and top and cover body joint, and wherein Fig. 5 (a) is security bar unfolding state figure; Fig. 5 (b) is attached to antenna surface state diagram for security bar.。
In figure: 1 is protecting film, 2 is non-drying glue layer, and 3 is edge sealant, and 4 is guarded antenna.
Embodiment
Below in conjunction with accompanying drawing, structural principle of the present utility model and operation principle are described in further detail.
Referring to Fig. 1,2,3, a kind of airborne antenna windward side security bar, comprises protective filmy layer 1, and protecting film 1 back side is for being non-drying glue layer 2, and protecting film edge is edge sealant or epoxy adhesive 3.Edge sealant or epoxy adhesive can be protected the composition surface of security bar edge and guarded antenna 4, adopt aviation-grade product.
Described protecting film can adopt polyester film or polyurethane film.
Described non-drying glue layer 2 is double faced adhesive tape, can directly be bonded to by protection coating.
The cover antenna windward side of described protecting film, its length is determined according to the height of antenna windward side, and width exceeds windward side 10～50mm, and thickness is 0.2 ~ 1mm.
Described non-drying glue layer is consistent with protecting film shape, and thickness is no more than 0.2mm.
Referring to Fig. 4, described airborne antenna windward side security bar be shaped as sword shape structure.
Referring to Fig. 5, the shape of described airborne antenna windward side security bar is T shape structure while launching.
Operation principle of the present utility model is:
During use, the double faced adhesive tape at protecting film 1 back side is directly bonded to by protection coating.
