Research on Tail-Sitter VTOL UAV Landing Technology Based on Pre-trained Bionic Technology

The Tail-sitter VTOL UAV adopts fuselage erection, VTOL, and overall commutation, resulting in poor stability of the UAV during landing and low adaptation to traditional landing devices. To solve the above problems, this paper proposes a Tail-sitter VTOL UAV landing gear based on Free-tail technology. Through the design of free tail structure and function integration, the landing gear is adapted to the vertical and level flight dual mode of the Tail-sitter VTOL UAV. In addition, with the pre-training learning of the dynamic landing process of the cat, the effective bionic simulation of the biological structure of the Tail-sitter VTOL UAV is realized, followed by the multi-objective optimization combined with the need for parameters in different modes of the UAV itself, which effectively improves the landing adaptability and stability.
