Vector aerodynamic rudder ducted fan for vertical takeoff and landing of unmanned aerial vehicle and control method thereof

Abstract

The invention discloses a vector aerodynamic rudder ducted fan for vertical takeoff and landing of an unmanned aerial vehicle and a control method thereof. The vector aerodynamic rudder ducted fan ischaracterized in that the vector aerodynamic rudder ducted fan comprises a cylindrical duct wall, a vector aerodynamic rudder ducted fan body, a vector aerodynamic rudder inner ring, a vector aerodynamic rudder outer ring, an annular bearing, an outer ring servo motor and a deflectable cascade of a vector aerodynamic rudder. The vector aerodynamic rudder ducted fan body is mounted on the cylindrical duct wall and located in the axial middle of the duct wall; the vector aerodynamic rudder inner ring is close to the lower end of the cylindrical duct wall and is fixedly connected with the duct wall; the vector aerodynamic rudder outer ring encircles the vector aerodynamic rudder inner ring, and the vector aerodynamic rudder outer ring and the vector aerodynamic rudder inner ring are spaced bya certain distance; the annular bearing is located between the vector aerodynamic rudder inner ring and the vector aerodynamic rudder outer ring and connects the inner ring with the outer ring; the outer ring servo motor is engaged with the vector aerodynamic rudder outer ring through a gear; and the cascade is mounted on the vector aerodynamic rudder outer ring and located at a bottom air outletof the vector aerodynamic rudder. The ducted fan pipeline design technology is adopted, so that the efficiency of the ducted fan is improved effectively; and lateral force is generated through the vector aerodynamic rudder to resist yawing caused by lateral wind, so that the heading direction and the airway are maintained.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a vector aerodynamic rudder duct fan and a control method for vertical take-off and landing unmanned aerial vehicles. Background technique [0002] Fixed-wing UAVs have many advantages such as large altitude, large flight speed range, long endurance, long range, and large payload. However, the fixed-wing UAV needs a certain length, width and surface quality to take off and take off from the ground as a take-off and landing site. As the weight of drones increases, the site requirements and airspace requirements for takeoff and landing increase. This site and airspace requirement is an important obstacle in the application of fixed-wing UAVs. [0003] In order to overcome and reduce this pressure on the take-off and landing site, catapult take-off and parachute landing have become an important breakthrough to solve the above difficulties. This take-off and landi...

Problems solved by technology

[0011] Aiming at the deficiencies in the prior art, the present invention proposes a vector aerodynamic rudder ducted fan and a control method for vertical take-off and landing UAVs, to solve the problem that the air free propeller in the prior art can only be applied to small, low-speed and unmanned vehicles. Man-machine, when the wind speed is high, the ability to resist crosswinds is poor, causing the UAV to yaw, unsafe
