Abstract
Embodiments include an aircraft comprising a fuselage; a wing connected to the fuselage; and first and second propulsion systems connected to the wing on opposite sides of the fuselage, wherein at least a portion of each of the first and second propulsion systems and at least a portion of the wing are tiltable between a first position in which the aircraft is in a hover mode and a second position in which the aircraft is in a cruise mode, wherein each of the propulsion systems includes pylon and a rotor assembly comprising a plurality of rotor blades.
Claims16
An aircraft comprising:
- a fuselage;
- a wing connected to the fuselage;
- and
- a pair of booms connected to opposite sides of the fuselage;
- an aft pair of boom-mounted propulsion systems mounted proximate aft ends of booms;
- a forward pair of boom-mounted propulsion systems mounted to forward ends of booms;
- and
- a pair of wing-mounted propulsion systems mounted to the wing on opposite sides of the fuselage;
- wherein each of the propulsion systems includes pylon and a rotor assembly comprising a plurality of rotor blades;
- and
- wherein at least a portion of each of the forward pair of boom-mounted propulsion systems and the wing-mounted propulsion systems are tiltable between a first position in which the aircraft is in a hover mode and a second position in which the aircraft is in a cruise mode.
An aircraft comprising:
- a fuselage;
- a wing connected to the fuselage;
- and
- a pair of booms connected to opposite sides of the fuselage;
- an aft pair of boom-mounted propulsion systems fixedly mounted proximate aft ends of booms, wherein the aft pair of boom-mounted propulsion systems are fixedly attached in a hover mode and cease rotation when the aircraft is in a cruise mode;
- a forward pair of boom-mounted propulsion systems rotatably mounted to forward ends of booms;
- a pair of wing-mounted propulsion systems rotatably mounted to the wing on opposite sides of the fuselage;
- and
- a tail assembly connected proximate aft ends of the booms aft of the aft pair of boom-mounted propulsion systems,
- wherein each of the propulsion systems includes pylon and a rotor assembly comprising a plurality of rotor blades;
- wherein at least a portion of each of the forward pair of boom-mounted propulsion systems and the wing-mounted propulsion systems are tiltable between a first position in which the aircraft is in a hover mode and a second position in which the aircraft is in a cruise mode.
An aircraft comprising:
- a fuselage;
- a wing connected to the fuselage;
- and
- three pairs of propulsion systems comprising:
- an aft pair of propulsion systems fixedly mounted to the aircraft aft of the wing on opposite sides of the fuselage;
- a forward pair of boom-mounted propulsion systems rotatably mounted to the aircraft forward of the wing on opposite sides of the fuselage;
- and
- a pair of wing-mounted propulsion systems rotatably mounted to the wing on opposite sides of the fuselage;
- wherein each of the propulsion systems includes pylon and a rotor assembly comprising a plurality of rotor blades;
- wherein at least a portion of each of the forward pair of propulsion systems and the wing-mounted propulsion systems are tiltable between a first position in which the aircraft is in a hover mode and a second position in which the aircraft is in a cruise mode.
