Abstract
The utility model discloses a cellular FRP antenna cover. The antenna cover is formed by the wrapping of a front cover and a rear cover. A chamber is formed inside the antenna cover. The top of the antenna cover is wider than the bottom of the antenna cover. The front part and the rear part of the antenna cover have a tapered structure. The antenna cover makes parts of radiators, installing plates and a feed structure wrapped to form an integral structure. The antenna cover which has a function of reducing wind resistance along an antenna flight direction prevents a balance feed structure from being eroded by rainwater, further prevents entries of foreign materials, and enhances the anti-load capabilities of an antenna. The antenna cover which exerts little influence on the electrical properties of the antenna can bear large emission power. Furthermore, the cellular FRP antenna cover which effectively solves the aerial carrier antenna wind resistance problem has the advantages of compact structure, lightness, simple manufacture process flow and low cost.
Description
Technical field
The utility model relates to a kind of radome technical field, particularly a kind of honeycomb fashion fiberglass radome.
Background technology
For the communication of aircraft needs, need at present a kind of simple in structure, lightweight, vertical tails frequency modulation broadcasting antenna of being fit to be installed on carrier aircraft of development; A kind of novel balanced feed structure has solved the matching problem of simple doublet antenna of version effectively in broadband (21%) scope, make it to satisfy frequency-modulated broadcast transmitter to the requirement of antenna input oral reflex; Because this antenna is installed aboard, must protect the antenna body covering; According to antenna installation position and the requirement of carrier aircraft mechanics, the design of radome must be satisfied following principle:
(1) do not affect the aeroperformance of aircraft;
(2) the not obvious antenna electrical performance that affects;
(3) do not reduce the mechanical strength of antenna body;
(4) antenna radiator and feed structure are implemented protection;
To satisfy simultaneously the advantages such as radome production process flow process is simple, cost is little;
But the radome of producing at present can not reach above-mentioned standard.
The utility model content
The purpose of this utility model is in order to solve the problem of above-mentioned existence, a kind of honeycomb fashion fiberglass radome to be provided, and it comprises a cover body, and described cover body is wrapped to form by front shroud and back cover, the described inner cavity that forms; Described cover body top Length Ratio low side is long.
Preferably, described cover body wraps up antenna body part, mounting panel and feed structure, forms integrative-structure.
Preferably, described cover body and antenna swathe the formation integrative-structure at many levels with epoxy cloth.
Preferably, antenna exposed parts, feed structure and the mounting panel beyond the described cavity has good contacting with body.
Preferably, described cover body adopts honeycomb fashion fiberglass electromagnetic wave transparent material as its moulding material.
Preferably, be used for wrapping up the saturating material of honeycomb fashion fiberglass of described feed structure in the edge of feed structure electric field.
Preferably, described cover body body profile is streamlined.
Preferably, described cover body is pressed the tapered structure of body heading front and back section.
Compared with prior art, the beneficial effects of the utility model are as follows:
(1) reduces antenna heading windage function;
(2) prevent that balanced feed structure is subjected to rain erosion, exotic entered function;
(3) increase the anti-load-carrying ability of antenna;
(4) very little on the antenna electric performance impact;
(5) can bear large transmitting power;
(6) the utility model technical pattern is compact, lightweight, fabrication processing is simple, cost is little.
Certainly, implement arbitrary product of the present invention and might not need to reach simultaneously above-described all advantages.

Embodiment
Below by preferred embodiment the technical solution of the utility model is described, but following embodiment can not limit protection range of the present utility model.
Fig. 1, Fig. 2, Fig. 3, a kind of honeycomb fashion fiberglass radome, its cover body is wrapped to form by front shroud and back cover, its inner cavity that forms; Its top Length Ratio low side is long; This antenna cover body wraps up partial radiation body, mounting panel and feed structure, forms integrative-structure.
A kind of honeycomb fashion fiberglass radome in the present embodiment, the long 1000mm in its top, the long 700mm of low side, width are 260mm, total height is 885mm; Being formed by front shroud and back cover of this honeycomb fashion fiberglass radome, front shroud and back cover wrap antenna body, this antenna works in 87～108MHz, antenna oscillator length is 1500mm, swathe at many levels front shroud and back cover with epoxy cloth again, antenna and cover body are rolled into integrative-structure, this structure makes feed structure and external isolated, prevent that balanced feed structure is subjected to rain erosion, exotic entered function, increased greatly the structural strength of antenna simultaneously.
The utility model is just used streamlined contour, and is designed to taper by section before and after the body heading, has effectively reduced the air drag that antenna bears, and has guaranteed that the aeroperformance of the rear aircraft of antenna installation is unaffected.
Such as Fig. 4, Fig. 5, the utility model adopts honeycomb fashion fiberglass electromagnetic wave transparent material as the body formed material of radome, makes the impedance operator of antenna seldom influenced, and the honeycomb fashion glass-reinforced plastic material of parcel feed structure is in the edge of feed structure electric field.
Antenna exposed parts, feed structure and mounting panel beyond the cavity have good contacting with body, effectively release electrostatic lotus and thunder-strike current, thus guaranteed the safety of antenna and aircraft.
Above embodiment only is used for illustrating content of the present utility model, and except above-mentioned execution mode, the utility model also has other execution mode, and all employings are equal to replaces or technical scheme that the equivalent deformation mode forms all drops in the protection range of the present utility model.
