The invention discloses a rotatable amphibious aircraft undercarriage, and relates to the technical field of aircraft undercarriages. The problem of energy consumption is solved. The rotatable amphibious aircraft undercarriage comprises two connecting frames connected with a fuselage, an overwater landing supporting mechanism and a land landing supporting mechanism, wherein the overwater landing supporting mechanism and the land landing supporting mechanism are used for amphibious landing. The same rotating mechanism is arranged on the outer walls of the overwater landing supporting mechanismand the land landing supporting mechanism, the rotating mechanism comprises a main gear, a first auxiliary gear and a second auxiliary gear, and the same connecting shaft is welded to the outer wallsof the two connecting frames. According to the invention, the rotating mechanism is arranged; the land landing supporting mechanism or the overwater landing supporting mechanism can be selected to work downwards for supporting according to the actual landing site, when landing is not needed, the land landing supporting mechanism and the overwater landing supporting mechanism are rotated to be horizontal, the windward area is greatly reduced relative to the working state, the flying wind resistance of the unmanned aerial vehicle can be reduced, and energy consumption is reduced.

    本发明公开了一种可旋转式的两栖飞机起落架,涉及飞机起落架技术领域;为了解决能耗问题;具体包括用于与机身连接的两个连接架和用于两栖降落的水上降落支撑机构和陆地降落支撑机构,所述水上降落支撑机构与陆地降落支撑机构的外壁设置有同一个旋转机构,所述旋转机构包括主齿轮、第一副齿轮和第二副齿轮,两个所述连接架的外壁焊接有同一个连接轴。本发明通过设置有旋转机构,可根据实际降落地点选择陆地降落支撑机构或者水上降落支撑机构向下支撑工作,当无需降落时,将陆地降落支撑机构与水上降落支撑机构旋转至水平,此时其迎风面积相对工作状态大大减少,可降低无人机飞行的风阻,降低能耗。
