The invention provides a tailstock type tailless layout amphibious aircraft adopting foldable wings and a design method, and relates to the field of amphibious aircraft design. According to the invention, aiming at a tailless-layout tailstock-type amphibious aircraft, by designing a foldable wing mechanism, the wings are unfolded to keep a high aspect ratio layout during air cruise, and the wings are folded to form an envelope layout for a fuselage during water surface dwelling and stopping; therefore, the aerodynamic performance requirement of the tailless layout tailstock type amphibious aircraft in an air cruising mode and the requirement of the tailless layout tailstock type amphibious aircraft in a water surface dwelling mode for the gravity center stabilizing distance and the floating stability are met, and the tailless layout tailstock type amphibious aircraft 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.
本发明提出一种采用可折叠机翼的尾座式无尾布局两栖飞行器及设计方法,涉及两栖飞行器设计领域。本发明针对无尾布局的尾座式两栖飞行器,通过设计可折叠的机翼机构,实现在空中巡航时,机翼展开保持大展弦比布局,而在水面栖停时,机翼折叠形成对机身的包络布局,从而满足无尾布局尾座式两栖飞行器在空中巡航模式对气动性能要求以及在水面栖停模式对重稳心距离和漂浮稳性要求,并在高海况条件下也可快速起飞。避免了传统尾座式固定翼飞行器在水面漂浮和空中巡航飞行两种状态下的重心、气动焦点和稳心之间的相对位置设计困难,传统布局设计难以保证飞行器在水面漂浮时稳定性的问题。
