Category tree inclding USPC 244/12.6, from USPTO site:[1]

  • USPC 244/12.1 Airplane and fluid sustained: Aeronautical machines having provision for sustentation in part or entirely by aerodynamic action on airfoils in fixed relation to the machines, having also provision for the sustention by the reaction to the downward movement of restricted masses or jets by air or other fluid, the forward propulsion of the machines may also be derived from movement of the same or similar masses or jets of air or other fluid. See USPC 244/15, for fluid propelled aircraft. See USPC 244/23, for aeronautical machines sustained solely by fluid reaction. See USPC 244/29, for lighter-than-air craft partially sustained by fluid reaction. See USPC 244/73+, for fluid propulsion and sustention devices, per se.
    • USPC 244/12.2 Circular: Apparatus wherein the peripheral surface of either the aeronautical machine or the airfoil therefor is substantially in the form of a circle.
    • USPC 244/12.3 Dual propulsion: Apparatus wherein the aeronautical machine comprises separate and distinct power plants or motive means, at least one of the motive means being used solely for forward or horizontal propulsion and at least one other motive means solely for lift or vertical propulsion.
    • USPC 244/12.4 Thrust tilting: Apparatus comprising an airfoil structure having an adjustable power plant or motive means thereon to provide a variable directional thrust to the machine, at least one component or direction of thrust being capable of providing lift to the machine. See USPC 244/56, for a tiltable power plant mounted to the fuselage of an aeronautical machine.
    • USPC 244/12.5 With thrust diverting: Apparatus wherein there is provided means on the aeronautical machine adjustable to a position for deflecting the direction of travel of exhaust fluid produced by the motive means, the deflector means when positioned to deflect the exhaust fluid providing a vertical or lifting force to the aeronautical machine for vertical or short take-offs and landings (V/STOL).
    • USPC 244/12.6 Channel wing: Apparatus wherein the airfoil fixed to the aeronautical machine is provided with an arched or other undulating configuration for confining, channeling or otherwise affecting, at least in part, the flow of sustention fluid therepast.
