| 摘要 | An aircraft comprises a plurality of wings. Each of the wings has a leading edge and a trailing edge and upper and lower surfaces defining an airfoil portion which produces a lifting force when the wing is moved through the air. At least a portion of the trailing edge of each wing is configured to define a semicircle. A power-driven rotor is mounted for rotation in the semicircle and has generally radial blades extending into close proximity with the semicircular surface portion of the trailing edge of the wing and arranged to produce a downward air flow at the trailing edge. The radial blades rotate in a plane that intersects the semicircular portion of the wing trailing edge, and increase the velocity of air flow across the upper surface of the airfoil portion and decrease the velocity of air flow across the lower surface of the airfoil portion thereby increasing the lifting capability of the airfoil. The tips of the rotor blades are located so that when they are in proximity to the trailing edge of the wing, the upper portion of each tip is below the upper edge of the semicircular portion of the wing trailing edge and above the lower edge thereof. The axis of rotation of the rotor corresponds approximately with the axis of the semicircle and may be canted relative to the forward direction of aircraft movement to provide a component of forward thrust. The wings are supported in a tandem, horizontally spaced relation so that a rotor located along the trailing edge of one of the wings increases the downward flow of air relative thereto and also increases the downward flow of air relative to the other wing, whereby each rotor associated with each wing augments or magnifies the downward flow of air produced by each other rotor so as to further produce additional lift for the aircraft. In addition, lighter-than-air bouyancy units may be connected to the opposite ends of each of the wings so as to further provide a lifting force on the aircraft. | ||||||
