  • Patent number: 11220996
    Abstract: A wind turbine includes at least one wind speed sensor, a number of pitch-adjustable rotor blades, and a control system for changing the pitch of the rotor blades and/or a generator torque. The the control system determines at time intervals an error parameter as the difference between an estimated wind speed and a measured wind speed as measured by the wind speed sensor. Then, based on a number of pre-defined wind speed intervals, a group of error parameters is obtained over time for each wind speed interval. For each wind speed interval and for each group of error parameters a wind speed offset is determined based on the average of the error parameters within the group which wind speed offsets are used in adjusting the measured wind speed.

  • Patent number: 11208987
    Abstract: Provided is a floating wind turbine including a hull, a wind turbine mounted on top of the hull and a counterweight suspended below the hull by a counterweight suspension is described. Also, a method for the installation is described. The counterweight includes one or more counterweight buoyancy tanks. When the internal volume of the buoyancy tanks is filled with air, the total buoyancy of the counterweight is close to or greater than its weight. Hereby it is capable of floating in a towing/maintenance position with moderate or no support in the vertical direction from the hull or other vessels. During towing, the hull substantially has the character of a barge, substantially relying on a large waterplane area and shallow draft to maintain stability.

  • Patent number: 11192644
    Abstract: A sleeve connecting a blade to the hub of a rotor of a rotary wing aircraft. The sleeve has a leading edge and a trailing edge, together with a protuberance arranged on the trailing edge. The dimensions of the protuberance are linked to the dimensions of the sleeve. The presence of the protuberance serves to improve the aerodynamic behavior of the sleeve and of the rotor during rotation of the rotor while the aircraft is moving forwards, both when the sleeve is advancing and when it is retreating. The presence of the protuberance also serves to reduce the vibration generated by a wake of the rotor on a tail boom or on a horizontal and/or vertical stabilizer of the aircraft.
