What are solar-powered unmanned aerial vehicles (UAVs)?
In the field of aviation, solar-powered unmanned aerial vehicles (UAVs) have attracted attention owing to their high-altitude cruise and the availability of renewable energy , .
Which energy supply system provides UAVs with energy during a cruise?
As shown in Fig. 1(a), the energy supply system, which includes photovoltaic and battery systems, provides the UAVs with energy during the cruise. The photovoltaic system contains photovoltaic arrays and a maximum power point tracker (MPPT).
How are solar-powered UAVs distributed?
Considering the actual situation in the flight process, the principle of energy distribution was used to distribute the energy inside the UAVs, and the energy distribution of solar-powered UAVs was optimized using a multi-objective genetic algorithm. A solution flow chart involving all models is shown in Fig. 7. Fig. 7. Model solving flow chart.
Are fuel cells a viable option for lightweight UAVs?
Fuel cells, particularly proton exchange membranes, demonstrate high energy density, enabling long flight durations for lightweight UAVs, yet face challenges such as slow response and hydrogen storage limitations.
