Solicitante:

WONG CARLOS [CN]
ZHUHAI KALUOSI MACAU ENG CONSULTANT LTD [CN]

CN_109838351_A

Resumen de: WO2019102434A1

A self-aligning to the incoming wind floating platform supporting multiple wind turbines(17, 18) forms a wind power generation unit. Under horizontal wind, the wind load resultant passes the center of geometry of the wind load receiving areas (hereafter C.Geo) of the floating platform, but not the turning axis (15), resulting a yaw moment about the turning axis (15) to turn the floating platform until the wind load resultant passes through the C.Geo and the turning axis (15) simultaneously. A wind park or wind farm comprises at least one floating platforms capable of self-aligning to the incoming wind for electric power generation. The floating platform helps to reduce the mileage of the submarine power cable (44), hence reducing the electric resistance and subsequently heat loss, and reducing the cost of submarine power cables (44).

LIFT-DRIVEN WIND TURBINE WITH FORCE CANCELING BLADE CONFIGURATION

NºPublicación: US2019136830A1 09/05/2019

Solicitante:

CONTINUUM DYNAMICS INC [US]

US_2016312765_PA

Resumen de: US2019136830A1

A lift-driven wind turbine has a turbine rotor with blades mounted to the turbine shaft by two struts hinged to the shaft and each blade to form a four-bar linkage. The blades' airfoil cross section generates lift that rotates the blades around the axis in the presence of a prevailing wind. The airfoil chord forms a geometric angle of attack αG relative to the tangent of the blade path and the struts orient the blades with an outward tilt angle γ. The turbine is designed with values of αG and γ that cause the lift generated by each blade to have an upward component that supports the blade against the force of gravity and a mean radially inward component that substantially balances centrifugal forces on the blade. Wind turbines designed according to the principles disclosed herein facilitate the construction of free-floating utility scale wind turbines for deep water installations.
