The E-Glifter concept is based in the Airbus E-Fan electric airplane architecture.
It features 4 rotors with 740mm diameter for stationary hover while it maintains the E-Fan glider shape during flight for an efficient cruise in order to meet the missions requirements.
Access to payload by medical staff is very easy, since it is loaded from upside. For this purpose and for safety reasons, lift rotors are retracted as soon as the E-Glifter lands.
This aircraft configuration has been chosen, since it is efficient in cruise as required by electric powered flight while it maintains a simple quadricopter arrangement for VTOL.
