Abstract
The invention belongs to technical field of aircraft structure design, and in particular to a kind of more interlayer honeycomb antenna houses using foam transition structure.The antenna house cover wall is made of honeycomb, foam, inside panel, exterior skin, force-supporting belt；Honeycomb, foam, force-supporting belt setting constitute sandwich between inside panel and exterior skin, and the transitional region of honeycomb and force-supporting belt is arranged in the foam.Wherein, honeycomb is equal thickness structure, and foam is Varying-thickness structure；Force-supporting belt is plated in by prepreg equal thickness.The present invention effectively improves the craftsmanship of more interlayer honeycomb antenna house transitional regions, effectively reduces antenna house weight by the variation to honeycomb sandwich construction antenna house transition region material；More previous more interlayer honeycomb antenna house transition regions, the transition region structural rigidity of such structure is big, and stress is less likely to occur under load effect and concentrates, and structure efficiency is high, significantly reduces the weight of transition region, has larger contribution to optimization antenna cover structure.
Description
Technical field
The invention belongs to technical field of aircraft structure design, and in particular to a kind of more interlayer bees using foam transition structure
Nest structural antenna cover.
Background technique
Existing honeycomb sandwich construction antenna house is mostly honeycomb transition structure, surface curvature is changed greatly or transition
Thickness change violent structure in area's is easy to appear the phenomenon that honeycomb is built bridge in forming process.This defect is difficult to mend in the later period
It rescues, the quality of product is influenced very big.
The present invention is a kind of more interlayer honeycomb antenna house foam transition structures, using such material transition structure shape
Formula can effectively improve the craftsmanship of typical cellular sandwich antenna house transition region, significantly reduce antenna house weight
Amount, improves the structure efficiency of antenna house.
Summary of the invention
Goal of the invention: providing a kind of more interlayer honeycomb antenna house foam transition structures, solves Curvature varying greatly and again
In the case that amount requires harshness, antenna house part transition problem.
Technical solution: because the transitional region craftsmanship of previous honeycomb sandwich construction antenna house is left to be desired, according to previous
Honeycomb sandwich construction antenna house transition region material selection, be easy to appear honeycomb arch formation, it is therefore desirable to design and verify
A kind of novel honeycomb sandwich construction antenna house transition structure is wanted with technologies such as the weight and the craftsmanships that meet existing antenna house
It asks.
A kind of more interlayer honeycomb antenna houses using foam transition structure proposed by the present invention, by honeycomb, foam, interior
Covering, exterior skin, force-supporting belt composition；The transitional region of honeycomb and force-supporting belt is arranged in the foam.
The present invention relates to a kind of more interlayer honeycomb antenna house foam transition structures, transition region cross-sectional view is as shown in Figure 1.
Honeycomb according to the present invention is equal thickness structure, and foam is Varying-thickness structure；Force-supporting belt is plated in by prepreg equal thickness.
It is connected using gluing.
For the ease of curing molding, in honeycomb sandwich construction be connected two layers between be provided with glue film.Adhesive uses FN305
Glue.The foam uses PMI foam.
Advantageous effects: the present invention is effectively changed by the variation to honeycomb sandwich construction antenna house transition region material
It has been apt to the craftsmanship of more interlayer honeycomb antenna house transitional regions, antenna house weight has been effectively reduced, to improve antenna
The economic benefit of cover.
More previous more interlayer honeycomb antenna house transition regions, the transition region structural rigidity of such structure is big, in load
It is less likely to occur stress concentration under effect, structure efficiency is high, the weight of transition region is significantly reduced, to optimization antenna house
Structure has larger contribution.
Detailed description of the invention
Fig. 1 antenna house transition region representative section figure
Number explanation: 1- exterior skin；2- honeycomb；3- foam；4- force-supporting belt；5- inside panel.
Specific embodiment
A kind of pair of interlayer honeycomb antenna house foam transition structure: by exterior skin, honeycomb, foam, force-supporting belt, inside panel
Composition；Varying-thickness foam is selected in honeycomb antenna house transitional region.Transition region cross-sectional view is as shown in Figure 1.Involved by the present invention
And honeycomb be equal thickness structure, foam be Varying-thickness structure；Force-supporting belt is plated in by prepreg equal thickness.Connected using gluing
It connects.
The foam uses PMI foam.For the ease of curing molding, in honeycomb sandwich construction be connected two layers between be provided with
Glue film.Adhesive uses FN305 glue.The honeycomb is made of paper honeycomb.The edge line of foaming structure is vertical with exterior skin.
Above-mentioned transition structure proposed by the present invention, the more interlayer honeycomb sandwich construction antenna house transitional regions of effective solution
Honeycomb bridge formation problem.The craftsmanship for effectively improving more interlayer honeycomb antenna house transitional regions, effectively reduces day
Irdome weight, to improve the economic benefit of antenna house.
At the same time, the more previous more interlayer honeycomb antenna house transition regions of structure proposed by the present invention, such structure
Transition region structural rigidity it is big, stress is less likely to occur under load effect and concentrates, structure efficiency is high, significantly reduces
The weight of transition region has larger contribution to optimization antenna cover structure.
