Abstract
A rotorcraft with distributed propulsion system having the capability to transition between two configurations suitable for thrust borne VTOL (vertical take-off and landing) flight and partial wing borne airplane flight. The rotorcraft includes a fuselage, an empennage, a vertical stabilizer, a rudder, a pair of wings, a pair of flaps, a pair of canards, a pair of pylons, a pair of tiltable rotor booms and a plurality of rotors. The tiltable rotor booms are associated with an actuator to change collectively the direction of the rotor thrust vector with respect to the fuselage. The rotor can be open rotor or ducted rotor. The rotor booms oriented in the canted position is the first configuration suitable for partial wing borne flight and the rotor booms oriented in the horizontal position is the second configuration suitable for thrust borne flight.
