ABSTRACT:
A fixed wing Vertical Take-Off and Landing (VTOL) aircraft for use as a Personal Air Vehicle (PAV) or unmanned vehicle. A first double-ended drive shaft engine is mounted sideways in the front of the fuselage to serve a first pair of ducted fans mounted at the ends of the front wing. A second double-ended drive shaft engine is mounted sideways in the rear of the fuselage to serve a second pair of ducted fans mounted on the rear fuselage. The ducted fans are rotatable from a horizontal orientation to a vertical orientation to permit the aircraft to take off and land as a VTOL or conventional aircraft, and to be flown as a conventional aircraft. A parachute is provided with inflation assistance to permit rapid low altitude deployment for a controlled descent of the aircraft in an emergency.
