Example Embodiment

[0032] Example 1

[0033] An oil-powered four-rotor unmanned aerial vehicle, comprising four rotors 1 and aero-engines 2, each rotor comprises two pieces of fins 11, and each piece of fins is respectively connected with a corresponding hub 12, and the aero-engine Through the reduction box 7, the power is transmitted to the four sets of gearboxes 4 through the four transmission shafts 3 arranged in a cross, and then the gearbox controls the two rotors connected to the two rotors through the servo steering gear 5 and the pitch variable system 6. The hub realizes the corresponding movement, and also includes a control system. The control system includes a variety of different types of sensors, flight control devices, measurement and control devices, mission equipment and flight control computers. The sensors are used to detect various types of aircraft. The flight control device uses the information collected by the acquisition board and the information detected by the sensor to ...

Abstract

The invention discloses an oil-driven four-rotor-wing unmanned aerial vehicle. The oil-driven four-rotor-wing unmanned aerial vehicle comprises four rotor wings and an aero-engine, wherein each rotor wing comprises two ribs; each rib is connected with a corresponding paddle hub; the aero-engine is used for transmitting power to four groups of speed changing boxes through four crossly-arrayed transmission shafts via a speed reducing box, and the two paddle hubs connected with the two rotor wings are controlled by the speed changing boxes through a servo steering engine and a pitch varying system to realize corresponding movement; and the oil-driven four-rotor-wing unmanned aerial vehicle further comprises a control system. The oil-driven four-rotor-wing unmanned aerial vehicle takes gasoline/aviation coal as fuel and takes the small-size aero-engine as power; a lifting force system adopts a helicopter rotor wing form; and a manipulation manner adopts a constant rotary speed and variable paddle pitch manner. The oil-driven four-rotor-wing unmanned aerial vehicle has the characteristics of long endurance time, great loading capacity, good maneuvering performance, strong anti-wind capability and the like. The work task requirements of almost customers can be met.

Description

technical field [0001] The invention relates to an aircraft, in particular to an oil-powered four-rotor unmanned aircraft. Background technique [0002] The oil-powered quadrotor aircraft is a multi-rotor autonomous aircraft powered by a small aeroengine and capable of vertical take-off and landing. It is a non-coaxial butterfly aircraft in terms of overall layout. Compared with conventional rotor aircraft, it has a more compact structure and can generate greater lift. Moreover, the four rotors can cancel each other's anti-torque torque without special anti-twist propeller. [0003] At present, there are many kinds of four-rotor and multi-rotor aircrafts on the market, all of which use lithium batteries as power sources, brushless motors as power, propellers as the lift system, and a control mode with fixed pitch and variable speed. The multi-rotor of the mode relies on its own gravity and the variable speed of the motor to change the lift force of the propeller ...
