Abstract: A vehicle having a first configuration for road use and a second configuration for air use, comprising: road wheels; a traction drive propulsion unit for driving road wheels when in contact with the ground; a thrust propulsion unit for driving a propeller to drive the vehicle through the air; and wherein, when the vehicle is configurable into any of: the first configuration, in which the traction drive propulsion unit is engaged to drive the road wheels on the ground, and the thrust propulsion unit is disengaged from the propeller; the second configuration, in which the traction drive propulsion unit is disengaged such that no drive is provided to the road wheels, and the thrust propulsion unit is engaged with the propeller to drive the vehicle thorough the air; or an intermediate configuration in which the traction drive propulsion unit is engaged to drive the road wheels on the ground, and the thrust propulsion unit is engaged with the propeller to drive the vehicle through the air.

Abstract: An aircraft, such as a flying car, comprising a body structure, lift structures (such as wings), control structures (such as fins, elevators, and ailerons), and a motor; a propeller connected to the motor and mounted for rotation about a drive axis to provide thrust; the propeller comprising a hub having a plurality of blades connected thereto; and a plurality of blade housings adjacent the propeller and extending substantially parallel to the drive axis; wherein the blades are mounted on the hub so as to be moveable between an expanded position in which the blades project radially from the hub, and a folded position in which each blade extends axially from the hub so as to lie in a respective blade housing.
