摘要
长航时无人机普遍采用大展弦比柔性机翼,本文首先分析了大展弦比机翼的特点和结构设计的难点,然后从材料应用、先进设计方法、结构形式三个方面分析了结构轻重量设计的关键技术,为实际大展弦比无人机机翼结构的研制提供参考。
Flexible wings with high aspect ratio are widely used in long-haul UAVs.In this paper,the characteristics of high aspect ratio wing and difficulties in structural desgin are analyzed at first.Then the key technologies of structural lightweight design are analyzed from three aspects:materal application,advanced design method and structural type.It provides a reference for the development of wing structure of UAV with high aspect ratio.
