Technical field
The utility model is related to machine design and manufacture field, and in particular to a kind of birotary engine layout is small-sized coaxial
Depopulated helicopter.
Background technology
At present, known small-sized unmanned helicopter is by dynamical system, fuselage platform, transmission system, manipulation and rotor
System, fuselage cover etc. are constituted, and because rotor system is using coaxial positive and negative double-deck rotor system, is eliminated tail-rotor, are made it have contracting
The characteristics of short fuselage length and lifting lifting capacity, small-sized unmanned helicopter engine system uses separate unit under normal circumstances
, installed in fore-body, there is both sides in complete machine layout in piston gasoline engine：One is piston type gasoline engine
The system of machine determines that power-weight ratio (abbreviation power to weight ratio) is smaller, and comparatively engine own wt is larger, the result is that
The own wt of depopulated helicopter complete machine is increased, makes its load-carrying commercial no more than 1/3,260 kilograms fly weights of total take-off weight
Measure commercial transport be no more than 85 kilograms, two be engine arrangement in front of fuselage and engine weight weight volume it is larger so that before fuselage
Weight is lacked of proper care afterwards, therefore is moved after load weight and can just be made main screw lift anterior-posterior balance, in the case where load-carrying is low, it is necessary to increase volume
Outer counterweight, causes to waste actual load-carrying and endurance efficiency, in addition in the case of the load (such as pesticide spraying) of weight change, such as
The whole load of fruit have been discharged with the time, body weight can be caused unbalance, and to prevent weight imbalance problem, actual load-carrying will be less than finger
Load-carrying is marked, separate unit piston gasoline engine complete machine flight safety coefficient is relatively low in addition, because dynamical system uses separate unit engine, if
Engine awing flame-out in flight for some reason, will cause aircraft accident.
Utility model content
For problem above, the utility model provides a kind of birotary engine and is laid out small-sized unmanned helicopter,
Using two New rotor engines as power set, engine is left and right symmetrically arranged on rotor axis, can solve to increase
Plus the technical problem of load-carrying commercial, reach and conventional load-carrying commercial is brought up to 1/2nd from 1/3rd of total take-off weight
Effect, while the problem of in-flight load weight change influence main screw lift is balanced can be solved.
To achieve these goals, the technical solution adopted in the utility model is as follows：A kind of birotary engine layout is small
Type unmanned helicopter, it includes fuselage girder, and the fuselage girder right-hand member is connected with vertical fin, the fuselage girder and installed
There are rotary engine and gearbox, the rotary engine is connected with gearbox by attachment means, the gear-box case
On to be provided with Servo-controller, the gearbox clutch end be to be connected with lower propeller hub, institute on outer shaft and interior axle, the outer shaft
State and propeller hub is connected with interior axle, the lower propeller hub is connected with lower rotor, the upper propeller hub is connected with rotor, interior axle and outer shaft
Rotate in opposite directions to drive rotor to rotate in opposite directions with lower rotor.
Further, the fuselage girder lower end is provided with foot stool.
Further, the upper propeller hub upper end is provided with trim tab system.
Further, the gearbox left end is provided with preceding fuel tank, and the gearbox right-hand member is provided with rear fuel tank, it is described before
Carburetor is provided between fuel tank and Servo-controller.
Further, it is provided with cooling water tank on the vertical fin.
The beneficial effects of the utility model：
The utility model is using two New rotor engines as power set, and engine left and right on rotor axis is right
Claim to install, can solve to increase the technical problem of load-carrying commercial, reach by conventional load-carrying commercial from the three of total take-off weight/
One brings up to 1/2nd effect, while the problem of in-flight load weight change influence main screw lift is balanced can be solved,
Small-sized unmanned helicopter load-carrying commercial increase, by heavy 80 kilograms of liftings published originally to 120 kg, unloaded or load-carrying dynamic change
In the case of complete machine can keep weight balancing, shut down if being happened suddenly in an engine flight, another engine can complete aircraft
It is urgent chase after drop, improve flight safety, it is unlikely to cause machine to ruin accident.
