Abstract
Aircraft apparatus and method capable of V/STOL (vertical, short takeoff and landing) in addition to conventional flight. For V/STOL operation, induced lift is provided by blowing air over the upper surface of each wing through a duct installed near the leading edge. Intake air is supplied to the blowing fan through a duct installed near the trailing edge, thus providing suction as well as blowing. Two fans in series are required. The engine provides power not only to the propeller but also to a transmission which provides power to the pulleys driving the belt-driven fans.
Claims10
An aircraft comprising:
- a fuselage;
- at least two wings, one wing on the left side of the fuselage and one wing on the right side of the fuselage, each of said wings having a high lift airfoil shape, each of said wings having a first elongate tangentially slotted duct proximate a leading edge of said airfoil and a second elongate tangentially slotted duct proximate a trailing edge of said airfoil;
- means for blowing high-pressure, high-velocity air through said first slotted duct along the upper surface of the wing and for sucking boundary layer air through said second slotted duct;
- and
- said means for blowing and sucking air comprising two sections, the intake of a first section in fluid communication with the second slotted duct on the right wing and the output of said first section in fluid communication with the first slotted duct on the left wing, and a second section having its intake in fluid communication with the second slotted duct on the left wing and its output in fluid communication with the first slotted duct on the right wing;
- whereby the simultaneous blowing and sucking of high-pressure air on each wing promotes laminar flow and increased lift for the aircraft.
In an aircraft comprising a fuselage, right and left wings, and an engine, the improvement for increasing the lift of the wings during landing and takeoff comprising:
- a pair of elongated slots proximate a leading edge of each wing;
- and a pair of elongated slots proximate a trailing edge of each wing;
- means for simultaneously blowing and sucking air driven by the aircraft engine;
- blowing duct means located in each of said wings proximate the leading edge and in longitudinal fluid communication with each respective blowing slot;
- sucking duct means located in each wing proximate the trailing edge and in longitudinal fluid communication with each respective sucking slot;
- and
- said blowing means comprising two sections, a first section having an intake attached to the sucking duct of the right wing and an output attached to the blowing duct of the left wing and a second section having an intake attached to the sucking duct of the left wing and an output attached to the blowing duct of the right wing.
