This two broad aspect of load, long endurance obtains considerable progress.The more rotors of propeller type can be achieved to fly by changing motor speed
Row device aerial statue and Heading control, but this improves and electrical motor gearshift performance and motor speed is accurately controlled to a certain extent
The requirement of technology;Furthermore the pitch of propeller is usually changeless, compared to variablepiston control rotor system, its
Pneumatic efficiency shows slightly deficiency.Under the equal power output of engine, the take-off weight to increase aircraft is more for propeller type
Rotor wing unmanned aerial vehicle most straightforward approach is increase propeller size with changing pitch.Increase the load of propeller type multi-rotor unmanned aerial vehicle
Another feasible scheme of Beijing South Maxpower Technology Co. Ltd's power be increase propeller quantity, increase to 8,18 it is even more more, but this mode can greatly
Reduce reliability, maintainability and the cruise-ability of aircraft.Therefore, propeller is not suitable for the multi-rotor aerocraft of big load.
Four rotor wing unmanned aerial vehicles be one kind can electricity oil two it is dynamic, be capable of the multi-rotor unmanned aerial vehicle of VTOL.It passes through balance four
Lift caused by secondary rotor and torque realize sustained turn and accurate flying.And automatic control technology, computer technology, communication
The fast development of technology, composite technology is with constantly bringing forth new ideas so that the development space of four rotor wing unmanned aerial vehicles is broader.It
Total arrangement belongs to non co axial formula symmetrical flight device in form, and compared with conventional rotary aircraft, its structure is more compact, energy
It is enough to produce bigger lift, there is its unique advantage compared with other aircraft.
Utility model content
The purpose of this utility model is to solve above-mentioned deficiency, there is provided a kind of four rotor wing unmanned aerial vehicle aircraft.
The purpose of this utility model is achieved through the following technical solutions:

Oar folder 11, the outer end of each oar folder 11 are respectively connected with a blade 10, the bottom of propeller hub 9 connection distance-variable rocker arm 12.
Nacelle radome fairing 8 is internally provided with motor.
Four nacelles provide support platform for fourth officer rotor, and four tops of frame are arranged in cruciform symmetry type.To the greatest extent may be used
It can reduce to close between rotor and ensure that the coordination of complete machine structure is compact on the basis of aerodynamic interference.Nacelle and mainframe are using only respectively
Meter is erected, is combined and is fastenedly connected with corresponding combining mechanism eventually through four primary load bearing bars.
Motor is individually fixed on main rotor side by motor cabinet, that is, realizes that driving in turn ensure that good radiating effect.
Motor regulates and controls rotating speed processed by electricity, and the little gear by connecting motor shaft drives and the affixed nylon gear wheel of rotor shaft, final to pass
It is handed to propeller hub and realizes gear.
