Abstract

A ducted- fan VTOL aircraft (1) in the mini and micro UAV classes, the aircraft (1) having a toroidal body (2) provided with a first axis (3) extending longitudinally along the toroidal body (2) and defining a fuselage (10) fitted with feet (4) for standing on the ground; the aircraft (1) also having a rotor (33) housed inside the toroidal body (2) and supported by the toroidal body (2), and a motor (9) having an output shaft (18) mounted to rotate the output shaft (18) about the first axis (3); the rotor (33) being a rigid rotor (33) fitted on the output shaft (18) and equipped with a plurality of blades (42), which are uniformly distributed around the first axis (3), each one having a respective second axis (43) arranged transversally to the first axis (3) and a respective pitch about the respective second axis (43); and, for each blade (42), respective first and second motorized control devices (23, 50) to collectively vary and, respectively, cyclically vary the respective pitch.
