The invention discloses a large space switchable dual-mode rotary supporting device and an aircraft. The switchable dual-mode rotary supporting device comprises a cabin body interface flange, a first rolling supporting assembly and a first switching locking mechanism, wherein the cabin body interface flange is provided with the first rolling supporting assembly and the first switching locking mechanism; the truss interface flange is provided with a second rolling supporting assembly and a second switching locking mechanism, and the truss interface flange can rotate relative to the cabin body interface flange in the main mode and the standby mode; the guide rail is arranged between the cabin body interface flange and the truss interface flange and matched with the first rolling supporting assembly and the second rolling supporting assembly, the first switching locking mechanism is used for unlocking the guide rail in the main mode and locking the guide rail in the standby mode, and the second switching locking mechanism is used for locking the guide rail in the main mode and unlocking the guide rail in the standby mode. The invention aims to solve the technical problems of low bearing capacity, high mass cost, short on-orbit service life, incapability of realizing single-mode fault elimination and the like of a sun-oriented driving mechanism.

    本发明公开了一种大型空间可切换双模式回转支撑装置和飞行器。可切换双模式回转支撑装置包括:舱体接口法兰,舱体接口法兰上设置有第一滚动支撑组件和第一切换锁定机构;桁架接口法兰,桁架接口法兰上设置有第二滚动支撑组件和第二切换锁定机构,桁架接口法兰在主模式和备模式下均能够相对于舱体接口法兰旋转;导轨,导轨设置于舱体接口法兰和桁架接口法兰之间,且与第一滚动支撑组件和第二滚动支撑组件配合,第一切换锁定机构用于在主模式下解锁导轨,在备模式下锁紧导轨,第二切换锁定机构用于在主模式下锁紧导轨,在备模式下解锁导轨。目的是解决对日定向驱动机构承载能力小,质量代价大,在轨使用寿命短,无法实现单模式故障消除等技术问题。
