Title: ULTRALIGHT MOTOR-DRIVEN AIRCRAFT
Abstract:
The invention relates to an ultralight electric motor-driven aircraft (10) comprising a rigid supporting structure (11) provided with a harness (20) for a pilot (9) and a sail (13) from which the supporting structure is suspended. A propeller (14), retractable during gliding flight, is powered by an electric motor (16) supplied with power by a battery (17). The battery (17) and the electric motor (16) are mounted in the supporting structure (11), on either side of the harness (20) for the pilot, such that the centre of the gravity of the aircraft substantially coincides with that of the pilot (9) in order to improve the aerodynamics and the stability of the aircraft.
