The current UAV market provides a vast selection of aircraft with useful loads ranging from grams to kilograms. However, commercial UAVs retain a limited operational range. With its compactness and weight, a LH2 powertrain increases the UAV range while safekeeping its useful load. Although its design remains challenging, solutions were found for the use case here presented: Drone Mermoz.
