AIRFOIL STRUCTURE, WING STRUCTURE AND ORNITHOPTER

WIPO Patent Application WO/2022/104769

A1

Embodiments of the present disclosure provide an airfoil structure, a wing structure and an ornithopter. The airfoil structure comprises multiple airfoil units. Adjacent airfoil units are connected by means of an airfoil control unit and an airfoil edge connector. Each airfoil unit comprises multiple airfoil edge piece and wing linkage connectors which are connected to each other. The wing linkage connector in each airfoil unit is correspondingly connected to a wing linkage set of the aircraft. Embodiments of the present disclosure provide an airfoil structure having wide-range morphing wing features in terms of chord length and camber variation. The motion of the airfoil structure is driven by the motion of the wing linkage set. The wing structure has wing morphing capability and high pitch angle variability, is capable of swinging within a wide range perpendicularly to the plane in which the main body of the aircraft is located, is capable of swinging within a wide range along the lengthwise direction of the main body of the aircraft, can adjust itself to a complex flow field or environment, can significantly improve the motion speed and the motion efficiency, and is capable of achieving high manoeuvring action.
