摘要： An aircraft (100) equipped with a distributed fan (162B) propulsion system and methods of operating such aircraft (100) are provided. In one aspect, an aircraft (100) includes a wing having a top surface (133) and a bottom surface (135). The aircraft (100) also has a distributed propulsion system (150) that includes a suction fan (162B) array having one or more fans (162A) mounted to the wing and a pressure fan array (170) having one or more fans (162A) mounted to the wing. The fans (162A) of the suction fan (162B) array are each positioned (50) primarily above the top surface (133) of the wing and the fans (162A) of the pressure fan array (170) are each positioned (50) primarily below the bottom surface (135) of the wing. The fans (162A) of the suction fan (162B) array are controllable independent of the fans (162A) of the pressure fan array (170) so that the air pressure above and/or below the wing can be locally controlled, allowing for adjustment of lift on the wing.

摘要： An aircraft (1) comprising a wing (3) having a spanwise lift distribution extending from a root (10) to a tip (12), the lift distribution defining an inboard region (14) defining a positive lift contribution, an outboard region (16) defining a negative lift contribution, and an intermediate region (18) defining a neutral lift contribution, the neutral region (18) being spaced from the tip (12) and from the root (10). A propulsion system is provided, comprising a wing mounted propulsor (5). The wing mounted propulsor (5) has a rotational axis (x) positioned substantially at a span of the wing (3) where a value of δLift / δSpan is at a maximum for the span of the wing, and may be located at the intermediate region (18) along the span of the wing (3).

摘要： A tiltrotor aircraft (10) has a fuselage (12) and a wing (18) having upper and lower surfaces (18a-b) with a plurality of channels (56a-d) extending therebetween, each with a cycloidal rotor (28a-h) mounted therein. At least two pylon assemblies (22a-b) are rotatably coupled to the wing (18) to selectively operate the tiltrotor aircraft (10) between helicopter and airplane flight modes. Each pylon assembly (22a-b) includes a mast (54) and a proprotor assembly (24a-b) operable to rotate with the mast (54) to generate thrust. At least one engine (40) provides torque and rotational energy to the proprotor assemblies (24a-b) and the propulsion assemblies. Each of the cycloidal rotors (28a-h) has a plurality of blades (108) that travels in a generally circular path and has a plurality of pitch angle configurations such that each cycloidal rotor (28a-h) is operable to generate a variable thrust and a variable thrust vector, thereby providing vertical lift augmentation, roll control, yaw control and/or pitch control in the helicopter flight mode.

摘要： The inventive method for producing a lifting force consists in forming a binary cyclone with the aid of thermal currents of at least one gas-jet device which are directed over the top surface of an object situated in the atmosphere of the Earth. Said binary cyclone is embodied in the form of at least one pair of contacting rotatable gas columns which are filled with said currents and flow over at least two areas situated on the top surface of said object. The inventive aeroplane comprises a top surface, at least one controlled gas-jet device and controlled aerodynamic elements, and is characterised in that the gas-jet device is arranged in such a way that the thermal currents directed over the top surface of the aeroplane produce a binary cyclone. The aerodynamic elements are arranged in such a way that the surfaces thereof are divergent from the currents of the binary cyclone. The inventive take off and landing method consists in producing the binary cyclone prior to take off and landing, in adding energy produced by fuel consumption to the currents of the binary cyclone in order to form sufficient lifting force values during take off and landing and sufficient impact air pressure currents flowing over the controlled aerodynamic elements. The displacement of the surfaces of the aerodynamic elements with respect to the currents of the binary cyclone is performed in such a way that the forces and moments stabilising the aeroplane are produced during take off and landing.

摘要： The aircraft includes a fuselage and at least one wing extending from the fuselage. The wing includes first and second original portions and a plug portion positioned between the first and second original portions. A propulsion system is positioned on the at least one wing. The propulsion system includes at least one electric powerplant and at least one combustion powerplant. Each powerplant delivers power to a respective air mover for propelling the aircraft. The electric powerplant and/or the combustion powerplant is positioned outboard from the plug portion. A method for retrofitting an aircraft includes segmenting a wing of an aircraft into two original portions, positioning a plug portion between the two original portions, and connecting the plug portion to one of the two original portions, the first nacelle and/or the second nacelle.
