Description

Many rotor unmanned helicopters
Technical field
The invention belongs to depopulated helicopter field, be specifically related to a kind of many rotor unmanned helicopters.
Background technology
Existing depopulated helicopter, it mostly is battery-driven rotor and lift and gesture stability are provided, it is subject to the restriction of battery capacity, lifting capacity and flying power are extremely limited, maximum load about 20 kilograms when general increase battery, cruising time is about 10 minutes, and due to the reason of battery, frequent flier needs to carry a large amount of set of cells, and the set of cells charging interval is oversize. Therefore, battery-driven unmanned air vehicle technique index seriously limits its applied generalization. Another kind of helicopter is the helicopter of the dynamic normal arrangement of single oil, is changed control flight attitude by the pitch of main rotor, but, its bad response, control accuracy is not high, poor reliability, and structure is complicated, fault rate is high, and too relies on Electronic Control, and electronic device breaks down very easily air crash.
Summary of the invention
In order to solve the problems referred to above that prior art exists, the invention provides a kind of many rotor unmanned helicopters, it has, and loading capacity is big, cruising time length, feature that reliability is higher.
The technical solution adopted in the present invention is:
A kind of many rotor unmanned helicopters, including fuselage, main rotor and secondary rotor system,
Described fuselage, is provided with to control the flight control system that described helicopter runs; Being also equipped with electric power system in described fuselage, described electric power system includes electromotor, electromotor and set of cells, and described electromotor drives described electromotor, and described electromotor provides electric energy for described set of cells;
Described main rotor, for providing lift for described helicopter, is vertically arranged in the top of described fuselage, and described main rotor is provided power drive by electromotor;
Described secondary rotor system, for changing the flight attitude of described helicopter, is fixed on all sides of described fuselage, and described secondary rotor system electrically connects with set of cells, and described set of cells provides electric energy to described secondary rotor system.
Further, described main rotor includes the first main rotor and the second main rotor, described first main rotor and the described second coaxial setting of main rotor, and the direction of rotation of described first main rotor and the second main rotor is contrary.
Further, being additionally provided with at least one fuel engines in described fuselage, described fuel engines drives described electromotor, and described fuel engines is connected with described first main rotor, the second main-rotor drive.
Further, described secondary rotor system includes multiple secondary rotor, and the quantity of described secondary rotor is 4,6 or 8, and all of described secondary rotor is evenly distributed on all sides of described fuselage centered by described main rotor.
Further, when described helicopter flight, described electromotor is the charging of described set of cells.
The invention have the benefit that electromotor drives the main rotor of contrarotation, main rotor provides prevailing lift, and the secondary rotor of 4 to 8, periphery is responsible for secondary lift and gesture stability. Owing to main rotor is spacing not tilting rotor, its first main rotor and the second main rotor positive and negative counter-rotation time, do not produce any deflection torque, though the electric propeller of gesture stability all lost efficacy also can vertical grease it in, simply lose the ability of moving in parallel. While starting to be contrarotation main rotor offer power, electromotor is also driven to be continuously set of cells charging, therefore, it may be achieved need not charge the battery and change battery and use immediately, it is not necessary to worry that dead battery falls machine. Lifting capacity and the cruising time of the present invention are greatly improved, and easily realize 50 to 200 Kg load and several hours even flying power of longer time.

In figure: 1, fuselage; 2, main rotor; 3, secondary rotor system; 4, electromotor; 5, set of cells; 6, flight control system; 7; Electromotor.
Detailed description of the invention
The invention provides a kind of many rotor unmanned helicopters, including fuselage 1, main rotor 2 and secondary rotor system 3, being provided with electric power system in described fuselage 1, described electric power system includes electromotor 7, electromotor 4 and set of cells 5, and described electromotor 4 electrically connects with described set of cells 5; Described main rotor 2, for providing lift for described helicopter, is vertically arranged in the top of described fuselage 1, and described main rotor 2 is driven by described electromotor; Described secondary rotor system 3, for changing the flight attitude of described helicopter, is fixed on all sides of described fuselage 1, and described set of cells 5 electrically connects with described secondary rotor system 3, and described secondary rotor system 3 provides power; It is also equipped with controlling the flight control system 6 that (be specially the taking off of aircraft, hover, advance, land and the action such as charging of electromotor and set of cells) described helicopter runs in described fuselage 1.
As an embodiment of the invention, as shown in Figure 1, multiple stage fuel engines 7 can be provided with in described fuselage 1, these electromotors 7 all can drive described electromotor 4 to generate electricity, when helicopter flight, electromotor 4 utilizes produced electric energy to charge for set of cells 5, therefore, without being individually for set of cells charging, also avoid the air crash accident caused because set of cells there is not electricity to run out of steam.
Described main rotor 2 includes the first main rotor and the second main rotor, described first main rotor and the described second coaxial setting of main rotor. Such as, the rotating shaft of the first main rotor and the second main rotor can vertically connect together, and keeps axis on the same line, and the first main rotor and the second main rotor are directly installed in respective rotating shaft, quick-disassembly structure can be passed through, it is achieved the installation and removal of the first main rotor and the second main rotor. Needs according to Different Altitude, are replaced main rotor, and main rotor is realized at each altitude by different rotating speeds. Therefore, not incline structure, this makes structure significantly simplify, and greatly increases reliability, almost without maintaining.
The output shaft of electromotor 7 connects helical gear and carries out power transmission, simultaneously described first main rotor, the second main rotor the tip of the axis that turns be equipped with helical gear, pass through meshed transmission gear, the rotating speed of the first main rotor and the second main rotor is identical, but direction of rotation is contrary, thus realizing the contrarotation of main rotor. Therefore, main rotor positive and negative counter-rotation time torsion cancel out each other, do not produce any deflection torque, it is not necessary to set up balance paddle, in hgher efficiency, and the most lift in helicopter flight process are provided.
Described secondary rotor system 3 includes multiple secondary rotor, and the quantity of described secondary rotor is 4,6 or 8, and in order to keep the steady of flight, all of described secondary rotor is evenly distributed on all sides of described fuselage centered by described main rotor. Flight control system 6 can drive the secondary rotor of four direction adjust fuselage balance by speed discrepancy and tilt, thus realizing the motion of each parallel direction. Main rotor is installed below pose adjustment rudder face, and gesture stability pair rotor can be coordinated under the control of flight controller to use, it is also possible to Emergency use after secondary rotor lost efficacy.
The present invention is not limited to above-mentioned preferred forms; those skilled in the art can draw other various forms of products under the enlightenment of the present invention; no matter but in its shape or structure, do any change; every have same or like with the application like technical scheme, all fall within protection scope of the present invention.
