Abstract
The presented results show that, for the considered drone segment, multirotor drones with weight of 7Â kg at take-off, lithium batteries are still the best choice for time flight shorter than about 1Â h. A hybrid system, appears to be interesting for longer flights. For example, it has been calculated that a hybrid quadcopter drone with a mass of 7Â kg, considering a flight profile that requires 1089Â Wh can be powered with a 4.4Â kg hybrid system composed by a 500Â W and 1.4Â kg PEM fuel cell system, 1.9Â kg hydrogen composite pressure vessel and a 0.8Â kg lithium battery. The same amount of energy can be stored in a lithium battery with a weight of about 6.6Â kg. These means a weight saving of more than 30%. The hybrid system, in term of weight, is even more convenient for flight profiles that require more energy.
