Description
Technical field
A kind of mini-sized flap wings formula helicopter, belongs to aviation aircraft field, more particularly to a kind of mini-sized flap wings formula is gone straight up to
Aircraft.
Background technology
Flapping-wing aircraft is the action and a kind of aircraft for developing for imitating birds flapping flight, flapping-wing aircraft using wing with
Air interacts to obtain lift of the air to flapping-wing aircraft, and in miniature low-speed operations device, flapping-wing aircraft has light-weight, body
The advantages such as product is small, using flexible, efficiency height.But current flapping-wing aircraft, such as crank double rocker mechanism flapping wing mechanism still
There is no good flying quality, the flapping-wing aircraft with superperformance needs more complicated torsion structure of fluttering, such
Flapping-wing aircraft is often huger, and such flapping-wing aircraft flexibility will substantially reduce, in addition such flapping-wing aircraft design
Also more difficult nursing and maintenance during difficulty Datong District.
The content of the invention
The present invention program is to for deficiency existing for such scheme, invent a kind of mini-sized flap wings formula helicopter.
A kind of mini-sized flap wings formula helicopter, including pinion gear, gear wheel, fixed frame, main shaft, engine, the first chain,
First axis of traction, the second chain, the first blade, the second axis of traction, pivoted arm, the second geometrical clamp, the second blade, the first geometrical clamp,
Second big sprocket wheel, the first big sprocket wheel, the second minor sprocket, the first minor sprocket, lift unit.
The fixed frame is the agent structure of mini-sized flap wings formula helicopter lift unit, and engine is fixed on fixed frame
Interior, pinion gear is connected with the output terminal of engine, and main shaft is installed on fixed frame by bearing；Gear wheel is installed on main shaft
And engaged with pinion gear, it is fixed in the middle part of pivoted arm on main shaft；During engine rotation, pinion gear also follows rotation, gear wheel and
Pinion gear is meshing relation, so power is transmitted on gear wheel, during bull gear drive, main shaft drives pivoted arm to rotate；First is small
Sprocket wheel and the second chainlet wheel construction are identical；First minor sprocket and the second minor sprocket are installed on main shaft by bearing, the first chainlet
Wheel and the second minor sprocket do not rotate together with main shaft；First axis of traction and the second traction axle construction are identical, they pass through bearing point
Not An Zhuan pivoted arm both ends；First big sprocket wheel is identical with second largest chain sprocket structure；First big sprocket wheel is installed on the first axis of traction
On, the first axis of traction is with rotation when the first big sprocket wheel rotates；Second big sprocket wheel is installed on the second axis of traction, the second big sprocket wheel
The second axis of traction is with rotation during rotation；First chain is installed on the first minor sprocket and the first big sprocket wheel；Second chain is installed
On the second minor sprocket and the second big sprocket wheel；First geometrical clamp is installed on the first axis of traction, and the first geometrical clamp fixes the first leaf
Piece；Second geometrical clamp is installed on the second axis of traction, and the first geometrical clamp fixes the second blade；First blade and the second blade construction
It is identical.
A kind of working method of mini-sized flap wings formula helicopter is：When mini-sized flap wings formula helicopter starts,
Engine in fixed frame, which is started to work, to be rotated, and drives the pinion rotation on engine output end because gear wheel with it is small
Gear meshing relation each other, so gear wheel also starts to rotate immediately.It is to use key connecting between gear wheel and main shaft, so greatly
Main shaft and pivoted arm also rotate therewith after gear rotates, and the first minor sprocket and the second minor sprocket on main shaft also together move；First
The transmission that the rotation of minor sprocket and the second minor sprocket passes through the first chain and the second chain so that the first big sprocket wheel and second largest chain
Wheel also rotates together；Since the first blade is fixed on the first geometrical clamp, the first geometrical clamp is connected with the first axis of traction, the first traction
Axis connection is in the first big sprocket wheel, so the first blade is synchronous with the movement of the first big sprocket wheel；Similarly, the movement of the second blade
Also it is synchronous with the movement of the second big sprocket wheel.And the movement relation of pivoted arm and the first blade and the second blade is：Pivoted arm rotates 180 °,
First blade and the second blade are rotated by 90 °, since the first blade and the second blade remain vertical, then on the outside of fixed frame
Blade all the time with ground level, the blade on the inside of fixed frame is vertical with ground holding all the time, so that the leaf in outside
Piece can produce lift always, and the blade of inner side be when rising it is vertical, the resistance of generation will very little, improve
The work efficiency of device.During the lift unit work of the helicopter both sides, there is provided upward lift, the propeller of helicopter
By varying angle of inclination, to realize advance or retrogressing.
Transmission mechanism of the present invention is simple, control is simple, and larger lift can be produced by taking full advantage of Outer blade, and be worked as
It is that the resistance produced is again few that blade, which rises, improves the flexibility of helicopter.
Fig. 1 is the top view of mini-sized flap wings formula helicopter, and Fig. 2 is the side view of mini-sized flap wings formula helicopter, and Fig. 3 is
The structure chart of lift unit, Fig. 4 are the cut-away views of lift unit.
In figure, 1- pinion gears, 2- gear wheels, 3- fixed frames, 4- main shafts, 5- engines, the first chains of 6-, 7- first are drawn
