Mixed tilt-rotor unmanned aerial vehicle

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 ...

AI Technical Summary

Problems solved by technology

However, because the Osprey is a dual-rotor tilt-rotor aircraft, the flight control system is relatively complicated. In vertical flight and in the transitional flight state of tilting vertical flight and level flight, there are problems such as poor longitudinal stability and difficult operation.
