Hybrid energy storage drone

What is a hybrid energy system for a UAV?

The development of UAV generally makes a trade-off between power density and energy density according to the mission. A better solution is the hybrid energy system, which can integrate the advantages of various energy sources.

How does a hybrid battery-solar cell UAV work?

When the UAV is cruising, it will transition to fixed-wing mode and use an ICE as a power source to increase endurance. Some hybrid battery-solar cell UAVs use solar energy to fly and store energy into the battery during the day and fly at night using stored battery power, which improves flight range and endurance.

Why is hybrid energy UAV a hot research area?

And hybrid energy system is expected to combine the advantages of these energy sources to build a better system. Therefore, hybrid energy UAV is a hot research area. Different types of UAVs have different requirements for energy propulsion. This chapter reviews the system components and classification of UAVs.

What is a hybrid drone?

A hybrid drone was designed to verify the performance of the self-made fuel cell . As shown in Fig. 13 A, the UAV is designed with a wingspan of 5050 mm, a fuselage length of 3000 mm, and a total weight of 21.19 kg. The hybrid energy of this drone is composed of a self-made PEMFC and 10S 3300 mAh 40C Li-Po battery.

Are hybrid energy UAVs a good choice?

A single energy propulsion system can hardly meet the requirements such as silent, long endurance, convenient take-off, low emissions, etc. Hybrid systems can combine the advantages of various energy sources. Therefore, researches on hybrid energy UAVs are widely carried out.

How can a hybrid system improve UAV performance?

The hybrid system of fuel cell and battery is a suitable solution to enhance the UAV performance. To further improve the cruising capability of the aircraft, solar cells are added to this hybrid system. Concomitantly, the three forms of energy increase the difficulty of implementing the hybrid system.
