What are the energy system states of hybrid electric UAVs?

The energy system states of hybrid electric UAVs are influenced by the flight mission. Various flight missions have different demand power for the hybrid energy system . For instance, energy system needs to provide high power during takeoff, turn, and climbing. During long endurance cruise flight, it needs to supply a continuous low power.

Which energy source is used in a UAV?

Lithium battery is the most commonly used energy source in UAVs, with a relatively high power density but a relatively low energy density. Solar cell can continuously harvest energy from flight environment, and convert it into electricity. However, the energy density and power density of solar cell are weak.
