Embodiment Construction

[0135] The validity of the solar rotor UAV system design method based on self-adjusting search pigeon swarm optimization proposed by the present invention is verified by specific examples below. In the example, the design mass is required to be no more than 3.2kg, the flight time is at least 1000 seconds, and it has the capability of long endurance, and there are no restrictions on the wheelbase, rotor area, etc.

[0136] Step 1: Solar Array Modeling

[0137] Based on the standard conditions of a certain solar cell (1000W / m 2 Take the data at 25°C) as an example, and substitute it into the single-cell model to obtain the output characteristics of a single cell. Among them, the size of the solar cell is 125×125 (unit mm), the mass is 7g, the short-circuit current is 6.28A, the open-circuit voltage is 0.787V, the maximum power point current is 5.93A and the maximum power point voltage is 0.582V. Set the light intensity to 500W / m 2 、700W / m 2 、900W / m 2 ; Set the temperature a...

Description

technical field [0001] The invention relates to a design method of a solar rotor unmanned aerial vehicle based on self-adjusting search pigeon group intelligence, and belongs to the fields of new energy and aviation technology. Background technique [0002] As one of the important types of UAVs, the rotor UAV has the advantages of small size, light weight, convenient operation, cheap and easy to obtain. Whether it is military reconnaissance and fixed-point strikes, or civilian drug spraying and disaster relief, rotor drones are indispensable. But the rotor UAV has an important defect-it consumes too much energy, and the time to perform a mission is much shorter than that of a fixed-wing UAV under the same conditions. It is more feasible to combine the solar cells with the rotor. As a clean and renewable energy source, solar energy has the advantages of abundant sources and easy access, which meets the country's strategic needs for energy conservation, emission reduction, a...
