Description
Technical field
The invention belongs to radome design fields, and in particular to a kind of radome root structure of foam enhancing.
Background technique
With the raising of aircraft technical level, increasingly higher demands are proposed to radome performance, radome is more next
It is more enlarged, it is more and more harsher by load, but weight indicator is required more and more tighter.
Radome is connect in its root with aircraft as shell, is typically employed in composite material cover root and is increased metal
Frame carrys out the mode of strengthen rigidity, and which weight loss effect is undesirable and assembly is complicated.
Summary of the invention
The present invention is directed to existing radome weight weight, assembles complicated problem, has invented a kind of rigid by foam enhancing root
The radome of degree, has weight loss effect good and radome assembly is simple.
The radome root structure of foam enhancing of the present invention, including exterior skin, honeycomb, inside panel, root foam and load
Band has been sequentially arranged the force-supporting belt, root foam and honeycomb along course between the exterior skin and inside panel；The Inner Mongol
Skin is inwardly protruding in the span scope of root foam.
Further, the longitudinal sectional shape of the protrusion is trapezoidal or arc.
Further, the exterior skin and inside panel are made of the molding of compound glass fiber prepreg material.
Further, the honeycomb is made of wave transparent paper honeycomb of good performance, and passes through glue film and exterior skin and Inner Mongol
Skin bonding.
Further, the root foam is made of PMI foam, Nian Jie with exterior skin and inside panel by glue film.
Further, the force-supporting belt is made of glass fibre prepreg identical with exterior skin and inside panel molding.
Further, root foam passes through foaming glue sticking with honeycomb, force-supporting belt respectively.
Further, the height of the protrusion is more than 3 times of thickness or more of honeycomb or force-supporting belt.
The utility model has the advantages that the present invention can effectively mitigate radome construction weight, radome assembly difficulty is reduced, improves assembly
Efficiency.
Detailed description of the invention
Fig. 1 is the radome root structure cross-sectional view of foam of the present invention enhancing.
Specific embodiment
Below in conjunction with Fig. 1, technical solution of the present invention is further described.
