Brief description of the drawings
Fig. 1 is with propeller to rotating motor structure chart.
Embodiment
The present invention is described in further detail with reference to embodiment, but the implementation of the present invention is not limited to this.
As shown in Figure 1, the present invention is by motor internal rotor 1, motor outer rotor 2, bearing 3, propeller 1 and propeller 25
Composition.Wherein, connected by bearings between motor internal rotor 1 and motor outer rotor 2, turned outside motor internal rotor 1 and motor
Son 2 is connected on bearing 3 by bearings respectively, motor internal rotor 1 and motor outer rotor 2 respectively with propeller 1 and spiral shell
Rotation paddle 25 connects and transmits shaft power.Motor internal rotor 1 and motor outer rotor 2 all add coil windings for the iron core of conventional motors
Structure, except that motor outer rotor 2 and being not fixed, it is not only rotated backward with respect to motor internal rotor 1, goes back relative seat
3 have rotation.Bearing 3 plays support and intermal force for frame structure, or tubular knot is further changed into the periphery of bearing 3
Structure is to serve as the by-pass air duct of propeller.The present invention is fixedly installed on aircraft by bearing 3.
The present invention has two kinds of working methods, the first, is used as aviation Air Turbine Generator.Specially：It incite somebody to action this
Invention installation on board the aircraft, and make it that the rotation axis of propeller is identical with heading.During aircraft flight, gas
Stream, which blows rotating propeller 1 and propeller 25, rotates its high speed, and then propeller 1 and propeller 25 are driven in motor respectively
Rotor 1 and motor outer rotor 2 rotate at a high speed in a reverse direction, so that aerodynamic energy is converted into electric energy.
Pattern is rotated backward since motor internal rotor 1 and motor outer rotor 2 are in opposite so that the relative rotation speed of both
It it is 2 times of single revolution speed of propeller or so, therefore, even if propeller has reached the maximum speed of design work state, by spiral shell
The motor internal rotor 1 and motor outer rotor 2 of rotation paddle driving can also have the relative rotation speed of higher, so that the present invention is used as air turbine
Generator, under same equipment volume and weight condition, the present invention can send the power of bigger, that is, the present invention has higher
Power to weight ratio performance.Further, since propeller 1 and propeller 25 are to rotate backward relatively, the propeller pair of air stream upstream
The propeller in downstream has air-flow rectified action, and causes the air rotational flow after downstream propeller to be led straight gyrus to propeller
Axis direction flows, so that kinetic energy absorption efficiency of the Air Turbine Generator to high-speed air flow is finally improved, that is, this
Invention can have the performance of more preferable energy conversion efficiency.
The 2nd kind of working method of the present invention, is to drive the aircraft power device of propeller to use as motor.Specifically
For：By present invention installation on board the aircraft, and lift or propulsion needed for the rotation axis and aircraft of two propellers are caused
Force direction is identical.During aircraft flight, airborne power supply is powered to the motor internal rotor 1 and motor outer rotor 2 of the present invention
To drive the relatively high speed rotation of both, motor internal rotor 1 and motor outer rotor 2 drive propeller 1 and propeller respectively again
25 rotations, then propeller 1 and propeller 25 are rotationally advancing acquisition pulling force in the air stream, this pulling force promotes aircraft to fly
OK.
Pattern is rotated backward since motor internal rotor 1 and motor outer rotor 2 are in opposite so that the relative rotation speed of both
It it is 2 times of single revolution speed of propeller or so, therefore, even if propeller has reached the maximum speed of design work state, motor
Internal rotor 1 and motor outer rotor 2 can also have a relative rotation speed of higher, constant equivalent to electric motor load torque and rotating speed is double,
It is exactly the power that motor can send bigger；The present invention between motor and propeller without setting retarder, so that same
Under equipment volume and weight condition, the present invention can send the power of bigger as electric propulsion power set, that is, the present invention has
The power to weight ratio performance of higher.Further, since propeller 1 and propeller 25 are opposite rotate backward so that air stream downstream spiral shell
Air rotational flow after rotation paddle is led straight gyrus and is flowed to propeller axis direction, is lured so as to reduce the air stream after propeller
Loss is led, improves propeller efficiency.
Specific embodiment 1：Air Turbine Generator without by-pass air duct.Bearing 3 is easy frame structure, motor internal rotor
1 and motor outer rotor 2 be installed to by bearing on bearing 3, bearing 3 is installed fixed on aircraft again.
Specific embodiment 2：There is the electric propulsion device of by-pass air duct.Bearing 3 is peripheral to be columnar structured, columnar structured into stream
Line style, it is columnar structured to serve as by-pass air duct；Columnar structured inner side is provided with supporting item, motor internal rotor 1 and motor outer rotor 2
It is installed to by bearing on the supporting item of bearing 3.Bearing 3 is installed fixed on aircraft again.In the course of work of the present invention, outside
Duct wall streams loss between reducing the paddle of propeller；By-pass air duct forward position forms larger negative pressuren zone and produces additional pulling force；And
Slip-stream area after propeller increases so that aerodynamic energy is more converted into pressure energy after paddle.Therefore, the presence of by-pass air duct, carries
The high work efficiency of electric propulsion device.By-pass air duct also acts as the effect of envelope propeller, can effectively protect high-speed rotating
Scratch of the propeller to foreign object around is wounded, and also can effectively protect propeller to be damaged from foreign object strike.
