A guide to unmanned aerial vehicles performance analysis—the MQ‐9 unmanned air vehicle case study by Erietta Zountouridou, George Kiokes, Aris Dimeas, John Prousalidis, Nikos Hatziargyriou

“…The required power depends on the UAV's flight stage from takeoff to landing, whereas its calculation varies with regard to the propulsion system type, which is separated into two main categories, the propelled‐driven engines and the jet engines. Two obstacles are arising. First, the parameters needed for the power estimation are commercially sensitive and second the analysis alters with respect to the engine's type. …”
