Abstract
Air acceleration at slot of aircraft wing. In one embodiment, a wing includes an air duct configured to transport air in a spanwise direction along a leading edge of the wing from an air supply source of the aircraft. The wing further includes a discharge duct configured to transport the air in an aft direction from the air duct to an aft end of the wing, and one or more nozzles disposed on the aft end of the wing and configured to accelerate air into a slot between the wing and a flap of the aircraft to increase lift and reduce drag for the wing.
Claims20
A wing of an aircraft, the wing comprising:
- a flap disposed on an aft end of the wing;
- an air duct configured to transport air in a spanwise direction along a leading edge of the wing from an air supply source of the aircraft;
- a discharge duct, disposed within the wing, configured to transport the air in an aft direction from the air duct to the aft end of the wing;
- and
- one or more nozzles, coupled with an aft end of the discharge duct, disposed on the aft end of the wing and configured to increase lift and to reduce drag for the wing by accelerating the air from the discharge duct into a slot between the wing and the flap.
A wing including a slot between a main wing element and a flap, the wing comprising:
- an inlet port, disposed within the slot, configured to suction a viscous layer of a lower surface of the wing;
- a compressor configured to pressurize air suctioned by the inlet port;
- and
- an ejection port, disposed within the slot, configured to increase lift and to reduce drag for the wing by ejecting the pressurized air into the slot,
- wherein the flap is disposed on an aft end of the wing.
A method of improving aerodynamic airflow for a wing of an aircraft, the method comprising:
- receiving, in an air duct disposed within an interior of the wing, air from an air source supply;
- transporting the air within the wing toward an ejection port disposed at a surface within a slot between a main wing element and a flap, wherein the flap is disposed on an aft end of the wing;
- and
- increasing lift and reducing drag of the wing by ejecting the air into the slot.
