Oil-driven four-rotor-wing unmanned aerial vehicle

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 ...

AI Technical Summary

Problems solved by technology

[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 for balanced control. The disadvantage is that the maneuverability is poor and the wind resistance is weak.

In addition, currently restricted by the power-to-weight ratio of batteries, they are all small and micro aircraft with short battery life and small load capacity.

Unable to meet the job task needs of most customers
