Abstract: A fly/drive vehicle has a road riding condition and a flying condition, and is easily convertible between the road riding condition and the flying condition. The vehicle includes a body with a passenger compartment and a drive compartment, at least one steered wheel and at least one driven wheel, and a propulsion propeller. The propulsion propeller has a central propeller base projecting outside a longitudinal end of the vehicle, and two propeller blades hinged to the central base. In the flying condition, the propeller blades are in an operative spread-out position, in which they extend substantially in line with each other substantially perpendicular to the propeller's rotation axis. In the road riding condition, the propeller blades are hinged about substantially vertical hinge axes to be directed more parallel to the longitudinal direction.

Abstract: A flying passenger rotor lifted vehicle that is capable of taking off and landing vertically, that is relatively light-weight, has responsive control, and increased safety against failure of propulsion/thrust systems. The flying vehicle can include a body having a tail section, a central thrust unit arranged along the longitudinal axis of the vehicle, at a distance from the rotation axis of the main rotor, a mounting support on either side of the body, and a side thrust unit mounted to each mounting support. The central thrust unit includes a fan which provides air flow with a flow component perpendicular to a virtual vertical midplane of the vehicle. Each of the side thrust units includes a fan which provides air flow with a flow component parallel to the virtual vertical midplane. At least one of the thrust units has controllable air deflection to deflect the corresponding output air flow in a controllable manner.
