A vertical or short takeoff and landing (V/STOL) airplane is described
having a vertical form factor. Making the airplane tall has many
advantages when operating in hover mode close to the ground. Several
variations of the design are described. The preferred embodiment consists
of two tall fuselage structures having an airfoil shape in plan view. As
high above the ground as practical a "lift wing" spans the space between
these fuselages. This wing may be equipped with lift augmentation systems
to facilitate V/STOL flight. In the center of the span on the leading
edge of the lift wing is placed a turboprop engine. Alternatively, the
wing and attached engine can be made to tilt about a horizontal axis. For
takeoff the wing will be tilted skyward. A second wing slightly below and
behind the lift wing has a pusher engine located on the trailing edge.
This lower wing and engine is also able to tilt about a horizontal axis
parallel to the lift wing. During takeoff this lower engine is pointed
downward toward the ground. This lower wing contains aerodynamic control
surfaces to provide attitude and position control. Subsequent to liftoff
the wings and engines tilt into a horizontal position to provide cruise
lift and thrust. At the end of the flight the wings and attached engines
are tilted back to provide vertical lift for hover, maneuvering, and soft
landing.
