Patent number: 11472543Abstract: A convertiplane is described that has a fuselage with a first axis, a pair of half-wings, and a pair of rotors arranged on mutually opposite ends of the half-wings. The rotor comprises a mast hinged on a second axis and a plurality of blades hinged on the mast. The mast of the rotor can be tilted with the second axis about a third axis transversal to the second axis and with respect to the fuselage to transform the convertiplane between a helicopter mode and an aeroplane mode; the second axis is transversal to the first axis in the helicopter mode and is parallel to the first axis in the aeroplane mode. The rotor disc can be tilted about a fourth axis.Type: GrantFiled: December 27, 2018Date of Patent: October 18, 2022Assignee: LEONARDO S.P.A.Inventors: Paolo Brughera, Paolo Sportelli, Pierre Abdel Nour, Andrea Bernascone, Cristian Lilliu

Patent number: 8989921Abstract: An electronic flight control system for an aircraft capable of hovering and having at least one rotor. The flight control system is configured to operate in a manual flight control mode, in which the flight control system controls rotor speed in response to direct commands from the pilot; and in at least two automatic flight control modes corresponding to respective flight modes of the aircraft, and in which the flight control system controls rotor speed automatically on the basis of flight conditions. The flight control system is also configured to memorize, for each automatic flight control mode, a respective flight table relating different speed values of the rotor to different values of at least one flight quantity; and to automatically control rotor speed in the automatic flight control modes on the basis of the respective flight tables.Type: GrantFiled: June 10, 2010Date of Patent: March 24, 2015Assignee: Agustawestland S.p.A.Inventors: Fabio Nannoni, Pierre Abdel Nour, Marco Cicaleā²
