Foam-reinforced radome root structure

The invention belongs to the field of radome design, and particularly relates to a foam-reinforced radome root structure. A radome serves as a shell, and the root of the radome is connected with an airplane. Usually, a mode that a metal frame is additionally arranged at the root of a composite material radome body to enhance rigidity is adopted, and the mode is poor in weight reduction effect andcomplex in assembly. The foam-reinforced radome root structure comprises an outer skin, a honeycomb, an inner skin, root foam and a force bearing belt, wherein the force bearing belt, the root foam and the honeycomb are sequentially arranged between the outer skin and the inner skin in the heading direction; the inner skin protrudes inwards within the span range of the root foam. The structural weight of the radome can be effectively reduced, the radome assembling difficulty is reduced, and the assembling efficiency is improved. 本发明属于雷达罩设计领域，具体涉及一种泡沫增强的雷达罩根部结构。雷达罩作为壳体，在其根部与飞机连接，通常采用在复合材料罩体根部增加金属框来增强刚度的方式，该方式减重效果不好且装配复
