Research on The Aerodynamic Performance of Bionic Morphing Aircraft

This paper investigates the design and aerodynamic performance analysis of a bionic morphing albatross-inspired aircraft, aiming to achieve efficient and enduring flight in wind conditions. The aircraft utilizes morphing techniques, including variable sweep angle of the wingtip and synchronous extension and retraction of the tail, to meet various aerodynamic performance requirements. The effects of the morphing scheme on the lift and drag aerodynamic characteristics are studied, addressing the issue of increased wind resistance during headwind flight. Furthermore, taking inspiration from bird’s rolling methods, this study investigates the enhancement of aerodynamic performance during rolling maneuvers through asymmetrical wing pitching and single-sided wingtip sweeping. Through FLUENT calculations and flight simulations, the optimal wingtip sweep angle configuration under different flight conditions is analyzed, and the aerodynamic performance of the aircraft with morphing wings is verified.
