变体飞行器蒙皮材料与结构研究综述

变体飞行器最为重要的技术特征就是结构在变形过程中翼面保持光滑、连续和无缝,而变形蒙皮技术是保证该技术特征的关键。以变形方式和年代为主线详细地总结了变形蒙皮材料与结构的发展现状和未来趋势。从早期的"鱼鳞叠片"式传统滑动变形蒙皮到现在的复合式柔性变形蒙皮,可以看出复合化是变形蒙皮未来发展的必然趋势。

Review of Material and Structure for Morphing Aircraft Skin

The most important technical characteristic of morphing aircraft is that the wings remain smooth, continu-ous and seamless during deformation. Morphing skin technology is the key to ensure this technical characteristic. In present paper, the current situation and future trends of morphing skin materials and structures are summarized in detail in the form of deformation and chronology. The stiff skin like fish skin was used for morphing skin in the early stage of morphing air-craft and the composite structure is designed to have adequate elongation strain in the current studies. In a word, the com-posite structure tends to show more potential to be as morphing skins.
