The patent relates to a propulsion system for the vertical take-off and landing (VTOL) aircraft having tiltable tandem mounted ducted propeller propulsion units. The propulsion units are connectable together to form a closed fluid path when the ducts are positioned for horizontal forward flight and thereby present a one propeller disc area. When the ducts are tilted for vertical flight, the individual propulsion units become disconnected, thereby presenting double the thrust area desirable for vertical flight.
