PMI-foam-based reinforced radome

The invention, which belongs to the design field of an airborne radome, in particular relates to a PMI-foam-based reinforced radome. The radome with a thin wall structure has a simple structure and good electrical property but a common mechanical performance index. The PMI-foam-based reinforced radome comprises a thin-wall radome body arranged outside and PMI foam arranged inside. Therefore, a problem of the common mechanical performance of the radome with a thin wall structure is solved and the electrical performance index of the radome is realized. The PMI foam is used for filling the insidethe thin-wall radome for enhancement, so that the stiffness and strength of the thin-wall radome are enhanced and the electrical performance index is met. 本发明属于机载天线罩设计领域，具体涉及种PMI泡沫加强天线罩。薄壁结构天线罩的结构简单、电性能较好，但力学性能指标般。本发明的PMI泡沫加强天线罩，包括外部的薄壁天线罩和内部的PMI泡沫。能够解决薄壁结构天线罩力学性能般的问题，同时又能满足天线罩的电性能指标。在薄壁天线罩内使用PMI泡沫填充加强，能够增强薄壁结构天线罩的刚度和强度并满足电性能指标。
