The invention belongs to the technical field of air vehicle stealth, and particularly relates to a cavity structure using a wave-absorbing material. The cavity structure uses metal or a carbon fiber composite as a base, different positions of the interior of a cavity of the cavity structure are coated with different thicknesses or different types of wave-absorbing materials, through the wave-absorbing material application scheme designed through the design method, the wave-absorbing performance of a wave-absorbing material used for an air inlet channel can be effectively improved, and the potential of existing materials is achieved better; and the using zone of the wave-absorbing material is reduced, using of wide-frequency-band wave-absorbing materials is reduced, accordingly, the cost and difficulty of the wave-absorbing material scheme are decreased, and air inlet channel forward radar stealth is achieved with high efficiency and low cost.

    本发明属于飞行器隐身技术领域,具体涉及一种应用吸波材料飞行棋腔体结构,该腔体结构采用金属或碳纤维复合材料为基础,在其腔体内部上不同位置涂覆有不同厚度或不同类型的吸波材料,应用本设计方法所设计出的吸波材料应用方案可有效提高进气道用吸波材料的吸波性能,更大可能地发挥好现有材料的潜能;降低吸波材料使用区域,减缩宽频段吸波材料的使用,进而降低吸波材料方案的成本和难度,进而解决高效低成本地解决进气道前向雷达隐身问题。
