目的 解决隐身飞机在飞行过程中因吸波贴片自身过重产生巨大的飞行成本,吸波贴片在飞行条件下易产生划痕、损伤、材料损耗快,以及因修复工序复杂、耗时长产生大量维护费用等问题。方法 应用TRIZ理论进行分析求解,通过采用功能模型分析、因果分析等找到航空航天用吸波贴片成本高的关键缺陷,利用技术矛盾分析、物理矛盾分析、物场模型及标准解、小人法等工具得到多个解决方案。经过综合评估最终找到经济、易于实现的解决方案。结果 通过运用TRIZ理论,并且通过综合评价找到了减少吸波贴片成本的最优方案:吸波贴片中的吸波体由掺杂杂原子的石墨烯构成了多孔结构,增加了其吸波性能;再将材料与自愈合材料相结合,增加其自愈能力,从而得到吸波性能好、质量小、自愈合能力强的吸波贴片。结论 文中得出的结果对减少隐身战机吸波贴片成本的研究具有一定的理论指导意义,有助于减少高集成设备过多对人类及环境产生的危害。 相似文献

With the rapid development of stealth technique, carbonyl iron powder is regarded as an ideal radar absorbing material. In this paper, radar absorbing properties of carbonyl iron powder was investigated by using nano composite and macroscopic multi- layer composite approach. The machine- chemistry composite methods were employed during the experiment to produce nano composite absorbent. Two carbonyl iron powders named HP1, HP2 and nano powder named HP3 were employed. Absorbents were obtained by adding 10% HP3 powder with average size of 28 nm to the HP1 and HP2 carbonyl iron powders by weight respectively. By a series of composite techniques, sample plate with the radar absorbing coating was prepared. Compared with the single coating, the wave absorbing properties were significantly improved. The working band in which the wave reflectivity was less than 5 db was 4.8 ~ 18 GHz with the coating thickness of 1.0 mm. The lowest reflectivity was found to be 12.34 db at 8 GHz. The wave absorbing coating with thin thickness,broadband and strong absorbing properties was obtained. 相似文献
