ABSTRACT:
A rotorcraft is provided with laterally placed dual rotors which rotate in opposite directions with the axis through the center of the rotors being transverse to the longitudinal axis of the aircraft's fuselage. Between the two rotor hubs a wing structure is placed above and below the blades with the two wings joined together forming a leading edge outward of the blades' radius toward the designated front of the craft thus forming a sheltered wing structure that allows the two rotors to revolve in their retreating mode phase out of the air stream when the craft is in horizontal flight. A compressed gas ejection system would aid in the transition of the blades from operating in free air to operating within the sheltered wing structure. A louver system in the upper and lower wings would operate to allow air flow freely through the wing during the lifting or hovering mode. The entire assembly of the wing structure and the rotors can be maneuvered as a unit so that the flight characteristics would be similar to a helicopter.
