초록

A VTOL aircraft (100) is provided having a plurality of rotor blade sets (2) disposed at least partially beneath the fuselage (1). The aircraft is propelled vertically by means of the thrust generated from the rotating sets of rotor blades (2), and augmented by suction generated aerodynamic lift. At least a portion of the suction airflow (A) is displaced from the upper surface of fuselage (1), creating a region of low pressure. The negative pressure, or suction generated from the portion of the rotor blades (2) disposed beneath the fuselage (1) causes a ...
