In the present embodiment, the diameter of above-mentioned upper rotor 4 is less than the diameter of lower rotor 5, so that the diameter of lower rotor 5 is big
In the downwash flow area of upper rotor 4, it is to avoid air-flow phase caused by the diameter of rotor 5 is identical above and below existing coaxial anti-oar class unmanned plane
Mutually influence, improves the power performance of unmanned plane.
In the present embodiment, above-mentioned upper rotor 4 is fixedly mounted on primary spindle 3, that is, the pitch fixation of upper rotor 4 can not
Regulation, lower rotor 5 is connected with blade pitch control mechanism (not shown), and the blade pitch control mechanism is used for the oar for adjusting lower rotor 5
Away from.Specifically, the pitch of the present embodiment refers to blade angle, that is, rotor blade and Plane of rotation inclination angle, in certain limit
Interior, blade angle is bigger, and the windward side of blade is bigger, and the lift of generation is bigger, and torsional forces is also bigger, passes through the change of the blade angle
Change, by increasing capacitance it is possible to increase or reduce thrust or pulling force that lower rotor 5 is produced, so as to realize the control in unmanned plane course.Above-mentioned pitch is adjusted
Section mechanism is prior art, therefore its structure is not repeated herein, as long as the structure of the lower pitch of rotor 5 regulation can be realized,
It may be considered blade pitch control mechanism.
In the present embodiment, because the pitch of upper rotor 4 is fixed, the lower pitch of rotor 5 is adjustable, and the diameter of upper rotor 4 is small
In the diameter of lower rotor 5, it is different with the torsional forces that lower rotor 5 is produced now to inevitably result in rotor 4, there is torsional forces difference
Situation, now, in order to which offset torque power is poor, preferably realizes the balance of unmanned plane, the present embodiment is symmetrically set in the circumference of fuselage 1
If there is dry support arm 11, motor 8 is provided with each support arm 11, each motor 8 is all connected to controlling organization, and each
The output end of motor 8 is respectively connected with small rotor 7, and drives the small rotor 7 to rotate.By setting small rotor 7, when there is torsional forces
When poor, the torsional forces that upper rotor 4 and the generation of lower rotor 5 can be balanced by the rotation of small rotor 7 is poor, and then realizes nothing
Man-machine smooth flight.
In the present embodiment, above-mentioned small rotor 7 is preferably provided with 6, and above-mentioned 6 small rotor 7 rotates simultaneously, passes through control
The speed discrepancy of each small rotor 7 of system, both provided lift for unmanned plane, assists lower rotor 5 to control direction, can balance again
Torsional forces between rotor 4 and lower rotor 5 is poor.
According to statistics, unmanned plane cause of accident is that the dynamic failure of engine 61 of oil makes rotor run out of steam mostly, it is uncontrolled from
And cause air crash accident.And the setting of the above-mentioned small rotor 7 of the present embodiment, cause the He of rotor 4 in the dynamic failure of engine 61 of oil
When lower rotor 5 runs out of steam, small rotor 7 can be driven to rotate by motor 8, aid in unmanned plane safe falling, it is to avoid existing
When rotor 4 and lower rotor 5 run out of steam on unmanned plane, unmanned plane is caused to crash or injure surface structures and crowd because out of control.
In the present embodiment, above-mentioned small rotor 7 is horizontally disposed or with respect to the horizontal plane in angle setting, specifically can be according to need
Set, preferably to realize the lifting of unmanned plane performance.
Fig. 2 is can refer to, power supply 9 is provided with fuselage 1, above-mentioned power supply 9 is connected to motor 8, for motor 8
It is powered.In the present embodiment, above-mentioned power supply 9 is rechargable power supplies, and wherein charging modes can be entered when unused
Row charging or the setting generator in fuselage 1, the generator can be connected to the dynamic engine 61 of oil, for being moved
Electric energy can be converted into, to be charged to power supply 9.
Above-mentioned controlling organization includes remote manipulator (not shown) and communicates to connect and be located at remote manipulator
Circuit board (not shown) inside fuselage 1, the circuit board be connected to above-mentioned drive mechanism 6, blade pitch control mechanism with
And motor 8.By remote manipulator come remotely pilotless machine two sets of self-driving systems (rotation of i.e. upper rotor 4 and lower rotor 5, with
And the rotation of small rotor 7), enable to two sets of self-driving systems separate, again can be with mutually coordinated auxiliary in work.
In the present embodiment, pitch 10 is arranged with hollow shaft 2, the pitch 10 can coordinate above-mentioned small rotor 7, come more
The heading of the good control hybrid power unmanned plane, because pitch 10 is existing structure, will not be repeated here.
The hybrid power unmanned plane of the present embodiment, by being arranged with some small rotors 7 on the fuselage 1, in the upper He of rotor 4
Produced between lower rotor 5 torsional forces it is poor when, can be produced by the rotation of small rotor 7 to offset between upper rotor 4 and lower rotor 5
Raw torsional forces is poor so that unmanned plane normal flight.
By only setting blade pitch control mechanism at lower rotor 5, and the upper pitch of rotor 4 is fixed, needed in unmanned plane during flying
, can be by the cooperation of small rotor 7 when adjusting the pitch of lower rotor 5, balance paddle is poor away from the torsional forces that regulation is brought, to cause nothing
Man-machine normal flight, and the present embodiment only needs to control the pitch of lower rotor 5, is not necessary to consider the oar of the upper rotor 4 of control
Away from simplifying the operation difficulty of the coaxial anti-oar design of tradition, user's manipulation gets up to be more prone to.
Embodiment two：
The present embodiment is differed only in embodiment one：
In the present embodiment, the pitch of above-mentioned upper rotor 4 is equally adjustable, i.e., it is respectively connected with pitch tune as lower rotor 5
Mechanism is saved, by the blade pitch control mechanism, the pitch of rotor 4 can be adjusted, in order to improve the performance of unmanned plane.Need to refer to
Go out, when upper rotor 4 and lower rotor 5 are provided with blade pitch control mechanism, also occur between rotor 4 and lower rotor 5
The situation of torsional forces difference is produced, now the small rotor 7 in the present embodiment can still offset and be produced between rotor 4 and lower rotor 5
Raw torsional forces is poor so that unmanned plane normal flight.
Remaining structure of the hybrid power unmanned plane of the present embodiment and all same of embodiment one, therefore will not be repeated here.
Obviously, above-described embodiment of the present utility model is used for the purpose of clearly illustrating the utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.There is no need and unable to give all embodiments
