Flight capability for micro air vehicles is rapidly maturing throughout the aviation community; however, mission capability has not yet matured at the same pace. Maintaining trim during a descent or in the presence of crosswinds remains challenging for fixed-wing aircraft but yet is routinely performed by birds. This paper presents an overview of designs that incorporate morphing to enhance their flight characteristics. In particular, a series of joints and structures is adopted from seagulls to alter either the dihedral or sweep of the wings and thus alter the flight characteristics. The resulting vehicles are able to trim with significantly increased angles of attack and sideslip compared to traditional fixed-wing vehicles.
微型飞行器的飞行能力在航空界迅速成熟;然而,任务能力的发展速度还没有跟上。在下降或遇到侧风时保持配平对固定翼飞机来说仍然具有挑战性,但鸟类却能轻松完成。本文概述了采用变形来增强其飞行特性的设计。特别是,从海鸥身上采用了一系列关节和结构来改变机翼的后掠角或梯形,从而改变飞行特性。与传统的固定翼飞机相比,所得到的飞行器能够在显著增加迎角和侧滑角的情况下配平。
