Embodiment Construction

[0025] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] In a specific embodiment, the propeller power cabin 8 can rotate around the shaft, and the cycloidal propeller 3 can change the size and direction of the thrust in the plane of symmetry of the aircraft arbitrarily and rapidly, realizing the difference between the multi-rotor mode and the fixed-wing mode. switch.

[0027] When the UAV is in the multi-rotor mode, the propeller power cabin 8 tilts upwards to be perpendicular to the axis of the fuselage 5, and the cycloid propeller 3 changes the position of the eccentric ring through the eccentric ring controller to a...

Abstract

The invention provides a tilt-rotor unmanned aerial vehicle with a cycloidal propeller tail fin. The tilt-rotor unmanned aerial vehicle is characterized in that the power is provided by combining a cycloidal propeller and propellers. A power part comprises two propeller power cabins at wing tips and the cycloidal propeller at the tail part; the two propeller power cabins can tilt for a large angle to change the thrust direction; the cycloidal propeller comprises cycloidal propeller blades, brackets, adjusting rods, a cycloidal propeller rotating shaft, driving devices, eccentric circular rings and an eccentric circular ring controller; and the thrust direction of the tail part is changed by changing the position of the eccentric circular ring. The tilt-rotor unmanned aerial vehicle can vertically take off and land and hovers in a multi-rotor aircraft state; and the tilt-rotor unmanned aerial vehicle has the advantages of high flying speed and high efficiency in a fixed-wing aircraft state. The tilt-rotor unmanned aerial vehicle integrates advantages of the multi-rotor aircraft and the fixed-wing aircraft and realizes broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of aviation vehicle design, and in particular relates to a tilting-rotor unmanned aerial vehicle which adopts cycloid propellers and propellers. Background technique [0002] For a long time, people have been looking for an aircraft that combines the advantages of multi-rotor aircraft and fixed-wing aircraft. After years of exploration and practice, such as the first generation of American tilt-rotor prototype verification aircraft XV-15, the already-serviced V-22 "Osprey" tilt-rotor aircraft, "Hawkeye" tilt-rotor UAV, etc. Military and civilian fields have played an important role and have broad development prospects. Tilt-rotor UAV not only has the advantages of multi-rotor UAV vertical take-off and landing, hovering in the air, but also has the same flight speed, range and load capacity as fixed-wing aircraft. However, because the Osprey is a dual-rotor tilt-rotor aircraft, the flight control system is ...
