The technical scheme of the invention is as follows:
high altitude wind power generation system based on unmanned aerial vehicle platform, it includes:
the generator is arranged on the ground;
and the large-airfoil high-lift-drag-ratio unmanned aerial vehicle drives the generator to generate electricity. The large-wing-surface high-lift-drag-ratio unmanned aerial vehicle is integrally distributed into a diamond shape through wings arranged on the left side and the right side of a streamline fuselage, a position control motor is arranged in the middle of the fuselage, a first attack angle adjusting rope and a second attack angle adjusting rope are respectively connected with the position control motor and a traction rope through the front end and the rear end of the fuselage, and the large-wing-surface high-lift-drag-ratio unmanned aerial vehicle is a small airplane, so that the first attack angle adjusting rope at the front end of the airplane is recovered and the second attack angle adjusting rope at the rear end of the airplane is released when the attack angle of the airplane needs to be reduced through the control of the position control motor; when the aircraft attack angle needs to be increased, the opposite operation is executed, the first attack angle adjusting rope at the front end of the aircraft is released, and meanwhile, the second attack angle adjusting rope at the rear end of the aircraft is recovered.

Detailed Description
The present invention is further described in detail below with reference to the attached drawings so that those skilled in the art can implement the invention by referring to the description text.
It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
As shown in fig. 1 and 2, the invention provides an aerial wind power generation system based on an unmanned aerial vehicle platform, which comprises:
a generator 1 arranged on the ground;
the large-airfoil high-lift-drag-ratio unmanned aerial vehicle 2 drives the generator 1 to generate electricity.
In the high-altitude wind power generation system based on the unmanned aerial vehicle platform, the large-airfoil high-lift-drag-ratio unmanned aerial vehicle 2 is connected with the generator 1 through a traction rope 3;
as shown in fig. 4, a first angle of attack adjusting rope 4 and a second angle of attack adjusting rope 5 are respectively fixed to the front end and the rear end of the large-airfoil high lift-to-drag ratio unmanned aerial vehicle 2.
In the high-altitude wind power generation system based on the unmanned aerial vehicle platform, the flight path of the unmanned aerial vehicle with the large airfoil surface, high lift-drag ratio is a straight line.
In the high-altitude wind power generation system based on the unmanned aerial vehicle platform, the angle between the flight trajectory of the unmanned aerial vehicle with the large airfoil surface, the high lift-drag ratio and the horizontal plane is 47 degrees.
In the high-altitude wind power generation system based on the unmanned aerial vehicle platform, the ascending speed of the large-airfoil high-lift-drag-ratio unmanned aerial vehicle is 0.4-0.45 times of the wind speed, and the descending speed is 1-2 times of the wind speed.
As shown in fig. 3, in the high altitude wind power generation system based on the unmanned aerial vehicle platform, the large-airfoil high lift-drag ratio unmanned aerial vehicle 2 is in a diamond shape, the long root ratio of the wing chord is 10, and the span length is 2 times of the root chord.
In the high-altitude wind power generation system based on the unmanned aerial vehicle platform, the same wing type is adopted for each section of the wing, and the wing type is EPPLER399 wing type. The layout scheme of the aircraft adopts the flying wing layout, and the flying wing layout has the advantages of high lift force, high lift-drag ratio, good structural strength and the like, and is very suitable for the high-altitude wind driven generator. The whole aircraft is in a large rhombus shape, the long root ratio of the wing chord is 10, and the wing span is 2 times of the root chord length.
The technical solution of the invention is as follows: the generator is arranged on the ground and driven by a small airplane. The airplane flies in a rising mode at a larger attack angle, and the airplane traction rope drives the generator to generate electricity; when the rope reaches a certain height, the posture is changed to dive downwards, and the generator recovers the rope, so that some energy is consumed; when the plane dives downwards for a certain distance, the posture of the plane is changed to climb upwards, and the power generation process is repeated. The electric energy consumed in the plane diving process is far less than the electric energy generated in the climbing process, so that the whole process achieves the power generation effect. The system mainly comprises two parts: 1. the large-airfoil high lift-drag ratio unmanned aerial vehicle; 2. the generator part is placed on the ground.
The same airfoil shape is selected for each section of the wing, and is EPPLER399 airfoil shape, and the airfoil shape also has the characteristics of high lift force and high lift-drag ratio. And the relative thickness is also larger, so that the structural strength of the whole wing is more suitable to be increased.
In order to facilitate control, mutual interference between the land and the aircraft is reduced, the flight track rises along the straight line direction, changes the posture after rising to the highest point, and dives down according to a path opposite to the rising track.
Control of the attitude of the aircraft is achieved by varying the lengths of two ropes directly connected to the aircraft: when the attack angle of the airplane needs to be reduced, the rope connected with the front end of the aircraft is recovered, and the rope connected with the rear end of the aircraft is released; when the aircraft angle of attack needs to be increased, the reverse operation is performed, releasing the ropes connected with the front end of the aircraft, and simultaneously recovering the ropes connected with the rear end of the aircraft.
As can be seen from FIG. 5, when the flight path of the aircraft selects a linear flight path which forms an angle of 47 degrees with the horizontal plane, the upward speed is 0.4-0.45 times of the wind speed, and the downward speed is 1-2 times of the wind speed, the wind energy utilization efficiency of the whole system in the whole period can reach more than 0.25.
While embodiments of the invention have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable in various fields of endeavor to which the invention pertains, and further modifications may readily be made by those skilled in the art, it being understood that the invention is not limited to the details shown and described herein without departing from the general concept defined by the appended claims and their equivalents.
