Abstract: The present invention relates generally to a system for automatically positioning a drone (1) on a landing/take-off site (2) comprising a landing area defined by an outer boundary, wherein the system is configured to position and align a drone (1), landed at any location on the landing area, at a predetermined position on the landing area, wherein the system comprises a rope sling (5) which, in its initial position, extends substantially along the outer boundary of the landing area, and the ends of which are connected to a rope winch (6) located near or at the predetermined position, so that the rope sling can be retracted when the rope winch is actuated, and wherein the drone is provided with engagement means (3, 4) configured to be engageable with the rope sling (5) when the rope sling (5) is retracted, so that the drone (1) is pulled to the predetermined position and is correctly aligned at the predetermined position upon further retraction of the rope sling (5).

Abstract: Embodiments of the present invention relate to a flight direction display method and apparatus, and an unmanned aerial vehicle. The method includes: obtaining a flight direction indication of an aircraft sent by a camera system, where the flight direction indication is determined by the camera system according to a relative angle between a camera apparatus and the aircraft; and displaying the flight direction indication of the aircraft on a shooting preview screen. In this way, a flight direction of the aircraft is controlled according to the flight direction indication, so that in a shooting process, a flight direction of a fuselage of the aircraft is the same as a rotation direction of the camera apparatus, so as to shoot content wanted by the camera apparatus, thereby improving user experience.

Abstract: A tilt driving mechanism comprises a housing fixedly mounted on the aircraft, a driving mechanism mounted in the housing, and a mounting seat flexibly mounted on the housing. A power unit is fixedly mounted on the mounting seat, and the driving mechanism is fixedly connected to the mounting seat, so as to drive the mounting seat to rotate with respect to the housing. The tilt driving mechanism is disposed on the aircraft, and a rotation angle of the tilt driving mechanism is controlled with high precision to change a direction of the power unit, so that the power unit switches between a lift force providing position and a thrust providing position. Meanwhile, the driving mechanism is disposed in the tilt driving mechanism, thereby significantly reducing a torque of the driving mechanism, facilitating miniaturization design of the tilt driving mechanism, and improving stability and safety of the tilt driving mechanism.

Abstract: A multirotor aircraft is provided. The multirotor aircraft comprises a body comprising a main body and a camera assembly with a camera coupled to the main body; a frame connected to the body, comprising a multirotor propulsion system; and a drive system coupled with the body and the frame, for driving the body to rotate against the frame. With the multirotor aircraft, full unobstructed 360° yaw field of view of the camera in the upper or lower hemisphere can be obtained and the camera is in a safe position at takeoff and landing.

Abstract: The present disclosure relates to aircraft technologies, and in particular, to a flight direction display method and apparatus, and an unmanned aerial vehicle. The method includes the following steps: obtaining a flight direction indication of an aircraft sent by a camera system, where the flight direction indication is determined by the camera system according to a relative angle between a camera apparatus and the aircraft; and displaying the flight direction indication of the aircraft on a shooting preview screen. In the present disclosure, the flight direction indication of the aircraft sent by the camera system is obtained, where the flight direction indication is determined by the camera system according to the relative angle between the camera apparatus and the aircraft, and the flight direction indication of the aircraft is displayed in the shooting preview screen.

Abstract: The present invention relates to an unmanned aerial vehicle (UAV), a power management system thereof, and a power management method therefor. The power management system includes a first power unit, a second power unit, and a power path controller. The first power unit and the second power unit are connected to a payload by using a switch unit, and the switch unit is electrically connected to the power path controller. The power path controller monitors flight mode information from a microcontroller unit of the UAV, determines a power module supplying power to the load according to the flight mode information, and switches on the first power unit or the second power unit to supply power to the load by controlling the switch unit. The power management system can increase endurance of the UAV, and can implement seamless and efficient switching between the different power modules.
