The invention provides a lifting force device for vertical take-off and landing of an aircraft, the aircraft and a fixed-wing aircraft. The lifting force device comprises a centrifugal impeller arranged above a supporting component; a power device which is arranged below the supporting component, wherein the power device is connected with the centrifugal impeller through a transmission shaft, the power device drives the centrifugal impeller to rotate through the transmission shaft, a negative pressure area is formed above the supporting component, and upward lifting force is generated on the supporting component; and a guide cover which is arranged on the periphery of the supporting component and connected with the supporting component through a connecting piece; wherein air pushed to the periphery of the supporting component by the centrifugal impeller forms airflow and is horizontally jetted to the guide cover, the direction of the airflow is changed through the guide cover to enable the airflow to be jetted downwards, and upward counter-acting force is generated on the guide cover. Lifting force can directly act on the aircraft body, the transmission shaft only drives the blades to rotate and does not bear the weight of the aircraft body and loads, and the safety and reliability of helicopters, rotary wing type unmanned aerial vehicles and vertical take-off and landing fixed wing aircrafts are greatly improved.

    本发明提供一种航空器垂直起降的升力装置、飞行器及固定翼航空器,包括:设置于支撑部件上方的离心叶轮;设置于支撑部件下方的动力装置,动力装置与离心叶轮通过传动轴连接,动力装置通过传动轴驱动离心叶轮进行旋转,在支撑部件上方形成负压区,在支撑部件上产生向上升力;设置于支撑部件外围的导向罩,导向罩与支撑部件通过连接件连接;被离心叶轮推向支撑部件外围的空气形成气流并水平射向导向罩,通过导向罩改变气流的方向使其向正下方喷射,在导向罩上产生向上的反作用力。本发明可使升力直接作用在航空器机体上,传动轴仅驱动叶片转动,不承受机体和载荷的重量,极大提高直升机和旋翼式无人机及垂直起降固定翼飞行器的安全性和可靠性。
