AI Technical Summary
Technical Problem
The tail-mounted fixed-wing water-air amphibious multimodal aircraft has low longitudinal stability performance when the water surface is on site, which is prone to overturning, and it is difficult to achieve surface retake after overturning.
Method used
The design of sliding foldable wings is adopted. The wings can move forward and backward along the fuselage axis under power drive and lock, and can be folded into a triangular structure to improve water surface stability.
Benefits of technology
It realizes that the aircraft maintains a tail-mounted state when the water surface is stationary, improves the stability of surface operation tasks, and can take off quickly under high sea conditions, combining efficient aerial cruise performance and surface stability.

Abstract
The invention provides a tailstock type amphibious aircraft adopting sliding type foldable wings and a design method, and relates to the technical field of amphibious aircrafts. By designing the slidable and foldable wing structures, different requirements of the tailstock type water-air amphibious multi-mode aircraft on the gravity center, the pneumatic focus and the steady center in the air cruising mode and the water surface dwelling mode are met, so that when the aircraft dwelling on the water surface, the aircraft can always keep a tailstock type state, the requirement for water surface operation tasks is met, and the aircraft has the advantages of being simple in structure and convenient to use. And the unmanned aerial vehicle can take off quickly under the high sea condition. The problems that the relative positions of the gravity center, the pneumatic focus and the stable center of a traditional tailstock type fixed wing aircraft in the water surface floating state and the air cruising flight state are difficult to design, and the stability of the aircraft in the water surface floating state is difficult to guarantee through a traditional layout design are solved.
