ABSTRACT:
A VTOL aircraft has a first engine nacelle mounted under the wing on one side of the fuselage and houses two of the aircraft engines. The first engine nacelle is mounted in close proximity with the fuselage. A second engine nacelle is mounted under the wing on the opposite side of the fuselage from the first nacelle and houses the remaining two engines. The second engine nacelle is mounted in close proximity with the fuselage. The first and second nacelles are movable from positions parallel to the wing for normal flight to positions perpendicular to the wing for vertical flight. Each of the first and second engine nacelles has inlets and nozzles and each of the first and second nacelles is angled in a manner whereby its nozzles are closer to the fuselage than its inlets. First control vanes extend aft of the nozzles of, and are movable with, the first engine nacelle and second control vanes extend aft of the nozzles of, and are movable with, the second engine nacelle. Each of the first and second vanes include vertical vanes normally aligned with the thrust vector centerlines.
