Abstract
The invention discloses a kind of honeycombs to mix sandwich radome, including exterior skin, inside panel, first honeycomb and the second honeycomb, first honeycomb and the second honeycomb is arranged between exterior skin and inside panel, first honeycomb is enclosed on the outside of the second honeycomb, the cellular thickness of described first is from its outer side to the second cellular direction gradually by thick thinning, and and the second honeycomb contact site reach identical as the second honeycomb thickness, the first honeycomb checkerwork cell is smaller than the second honeycomb checkerwork cell, it can satisfy the requirement of radome electrical property, simultaneously, the present invention also can satisfy radome strength and stiffness and meet the requirements.
Description
Technical field
The present invention relates to radome technical field, in particular to a kind of honeycomb mixes sandwich radome.
Background technique
Radar is the farsighted person of aircraft, person who can hear voices a long way off, and important feature functional component of the radome as radar system is
Radar provides excellent electromagnetic transparent window, while bearing various load and natural environment effect, protection radar system safety, thunder
It is mainly composite material sandwich structure up to cover, is exactly A type honeycomb sandwich construction wherein most popular, but current A type bee
Same honeycomb core material is mainly used in the design of nest sandwich radome, to meet its electrical property and intensity, rigidity
It can require, although can satisfy its electrical property and intensity, rigidity property needs substantially, as the requirement of radome electrical property is got over
Come higher, needs constantly to reduce covering and core layer thickness, and after covering and core layer thickness reduce, radome strength and stiffness but have
Declined, it is, therefore, desirable to provide a kind of honeycomb mixes sandwich radome, had not only been able to satisfy the demand of radome electrical property, but also
It may insure that radome strength and stiffness are met the requirements.
Summary of the invention
The purpose of the present invention: a kind of honeycomb mixing sandwich radome is provided, the need of radome electrical property be both able to satisfy
It asks, and may insure that radome strength and stiffness are met the requirements.
Technical solution of the present invention:
A kind of honeycomb mixing sandwich radome, including exterior skin, inside panel, the first honeycomb and the second honeycomb, it is described
The first honeycomb and the second honeycomb be arranged between exterior skin and inside panel, first honeycomb is enclosed in outside the second honeycomb
Side, the cellular thickness of described first is gradually thinning by thickness from its outer side to the second cellular direction, and contacts with the second honeycomb
Position reaches identical as the second honeycomb thickness, and the first honeycomb checkerwork cell is smaller than the second honeycomb checkerwork cell.
First honeycomb and the second honeycomb is aramid fiber paper honeycomb, and the first honeycomb checkerwork cell side length is 2mm, institute
The the second honeycomb checkerwork cell side length stated is 3mm.
A circle foamed glue is also coated on the first honeycomb thickness and the second honeycomb contact surface.
Beneficial effects of the present invention:
A kind of honeycomb mixing sandwich radome, including exterior skin, inside panel, the first honeycomb and the second honeycomb are provided,
First honeycomb is enclosed on the outside of the second honeycomb, the first cellular thickness is gradually become by thickness from its outer side to the second cellular direction
It is thin, and and the second honeycomb contact site reach identical as the second honeycomb thickness, while the first honeycomb checkerwork cell being designed to than
Two honeycomb checkerwork cells are small, can satisfy the requirement of radome electrical property, meanwhile, the present invention also can satisfy radome strength and stiffness
It meets the requirements.
Detailed description of the invention
Fig. 1 is that honeycomb of the present invention mixes sandwich radome diagrammatic cross-section；
It is identified in figure: 1, exterior skin, 2, inside panel, the 3, first honeycomb, the 4, second honeycomb.
Specific embodiment
The present invention is described further with reference to the accompanying drawing, a kind of honeycomb of the present invention mixes sandwich radome, packet
Exterior skin 1, inside panel 2, the first honeycomb 3 and the second honeycomb 4 are included, first honeycomb 3 and the second honeycomb 4 are arranged at outer illiteracy
Between skin 1 and inside panel 2, first honeycomb 3 is enclosed in the outside of the second honeycomb 4, the thickness of first honeycomb 3 from its
Outer lateral second honeycomb, 4 direction reaches and 4 thickness phase of the second honeycomb gradually by thick thinning with 4 contact site of the second honeycomb
Together, 3 checkerwork cell of the first honeycomb is smaller than 4 checkerwork cell of the second honeycomb.
First honeycomb 3 and the second honeycomb 4 is aramid fiber paper honeycomb, and the 3 checkerwork cell side length of the first honeycomb is
2mm, the 4 checkerwork cell side length of the second honeycomb are 3mm, and the first bee, 3 select the lesser honeycomb of checkerwork cell side length, can effectively protect
The integrally-built strength and stiffness of radome are demonstrate,proved, the second honeycomb 4 selects the biggish honeycomb of checkerwork cell side length, it is ensured that obtains in the region
Obtain excellent electrical property.
It is also coated with a circle foamed glue on 4 contact surface of first honeycomb 3 and the second honeycomb, when two kinds of honeycomb mouldings,
The gap of its contact surface applies one layer of foamed glue, makes the first bee, 3 and second honeycomb 4 be effectively connected as an entirety, reach and mention
The effect of high radome integral strength and rigidity property.
The present invention is by being enclosed in the outside of the second honeycomb 4 for the first honeycomb 3, and the thickness of the first honeycomb 3 is from its outer side to the
Two honeycombs, 4 direction gradually by thick thinning, and and 4 contact site of the second honeycomb reach identical as 4 thickness of the second honeycomb, simultaneously will
First honeycomb, 3 checkerwork cell is designed to smaller than 4 checkerwork cell of the second honeycomb, can satisfy the requirement of radome electrical property, meanwhile, the present invention
It can satisfy radome strength and stiffness to meet the requirements.
