| Abstract: | The hover duration performances of miniature vertical takeoff and landing (VTOL) air vehicles depend on the performance of propulsion system. Based on the mass models of battery, motor and electronic speed controller (ESC), and the relationship between provided force and required power of propeller, the duration calculation model of such vehicles is established by discharging battery pack with constant current. The influences of propulsion parameters and payload on vehicle duration are analyzed, which would be used for preliminary design of VTOL air vehicles and components selection of propulsion system. |
