A turbine airfoil unit is described which enables an aircraft to ascend and descend vertically. Multiple turbine airfoil units may be arranged within a large disk-like structure and thereby overcome size limitations placed on helicopters by their rotors. One or more central engines providing a flow of air under pressure relative to ambient air supplies power to one or multiple turbine airfoil units. The pressurized air from the engines is funneled into the containing disk-like structure and distributed to all turbine airfoil units encompassed therein. The supplied air acts on the turbines to rotate the airfoils and thus create lift. The lift is transmitted to the disk-like structure and to the remainder of the aircraft by bearings between the turbine airfoil unit and the containing portion of the disk-like structure. The large disk-like structure is known in the popular culture as a flying saucer.
