A vertical take-off and landing (VTOL) aircraft comprises (1) a fuselage
having a front end, a rear end and two lateral sides, the fuselage
defining a substantially horizontal central longitudinal axis of the
aircraft; (2) an aircraft tail arranged at the rear end of the fuselage
and including a rudder and an elevator on each side of the fuselage with
movable surfaces for controlling the aircraft; and (3) a wing on each
side of the fuselage having a front edge, a trailing edge and an upper
surface extending from the front edge to the trailing edge. According to
the invention, means are provided for increasing the speed of an
airstream flowing over the upper surface of each wing, and an air
deflector is disposed on each side of the fuselage between the trailing
edge of each wing and the aircraft tail. These deflectors each have a
deflection surface to deflect downward the airstream flowing over the
upper surface of the wing to act as a "brake" to the forward motion of
the aircraft and to provide additional lift so that the aircraft may
hover.
