110856 - A New Maneuver Design and Dynamic Control Strategy for Gull-Like Aircraft 

Bionic aircraft has the characteristics of high maneuverability, high concealment, and other significant advantages in high altitude reconnaissance and rescue assignments. At present, the problems of poor aerodynamic performance and high energy consumption ratio lead to the decrease of maneuvering performance of bionic aircraft. In this paper, a maneuvering aircraft with morphing wing is designed by studying the wing shape and flight attitude of seagulls, which can improve its aerodynamic performance by folding the wing and changing the sweep.

First, based on the design parameters and kinematic equations of the first designed gull-like aircraft, the aerodynamic characteristics, mode analysis and the stability were obtained by combining the overall design strategy and ANSYS simulation. Second, combined with the folding action of seagull wings, the influence of different folding modes of wings was conceived and analyzed. The maneuvering action of the wing was designed for flat flight, hover and dive, and the maneuvering performance of the aircraft is investigated by simulation. Then, the spinor theory was applied for the mathematical modeling of the aircraft, resulting in a more concise form of the attitude motion equation of the aircraft. Taking the folding Angle of the wing as the control quantity, the PID control method was applied on the spinor theory to control the maneuvering performance of the aircraft.

This paper aims to propose a new maneuver design and dynamic control strategy for gull-like aircraft to improves the maneuverability performance of the aircraft.
