Abstract

An adaptor assembly for coupling a blade root of a turbine blade to a root slot of a rotor disk is described. The adaptor assembly includes a turbine blade having a blade root and an adaptor body having an adaptor root. The adaptor body defines a slot having an open end configured to receive the blade root of the turbine blade such that the adaptor root of the adaptor body and the blade root of the turbine blade are adjacent to one another when the blade root of the turbine blade is positioned within the slot. Both the adaptor root of the adaptor body and the blade root of the turbine blade are configured to be received within the root slot of the rotor disk.

Adaptor assembly for coupling turbine blades to rotor disks

Patent Delvaux, John McConnel; Garcia-Crespo, Andres Jose; Joyce, Kilmer Joseph; ...

An adaptor assembly for coupling a blade root of a turbine blade to a root slot of a rotor disk is disclosed. The adaptor assembly may generally include an adaptor body having a root configured to be received within the root slot. The adaptor body may also define a slot having an open end configured to receive the blade root. The adaptor body may further define a channel. The adaptor assembly may also include a plate having an outwardly extending foot. The foot may be configured to be received within the channel. Additionally, the plate may be configured to covermore » « less

Wind turbine rotor blades with load-transferring exterior panels

Patent Caruso, Christopher Daniel; Stewart, Edward McBeth; Yarbrough, Aaron Alpheus

Rotor blades for a wind turbines include a structural support member disposed internal the rotor blade that extends for at least a portion of a rotor blade span length and an airfoil structure supported by the structural support member, the airfoil structure comprising a shell portion and at least one load-transferring exterior panel. The shell portion and the at least one load-transferring exterior panel combine to form an aerodynamic profile comprising a leading edge opposite a trailing edge and a pressure side opposite a suction side. Moreover, the shell portion and the at least one load-transferring exterior panel are independentlymore » « less

Multiple piece turbine rotor blade

Patent Kimmel, Keith D.; Plank, William L.

A spar and shell turbine rotor blade with a spar and a tip cap formed as a single piece, the spar includes a bottom end with dovetail or fir tree slots that engage with slots on a top end of a root section, and a platform includes an opening on a top surface for insertion of the spar in which a shell made from an exotic high temperature resistant material is secured between the tip cap and the platform. The spar is tapered to form thinner walls at the tip end to further reduce the weight and therefore a pullingmore » « less

Variable diameter wind turbine rotor blades

Patent Jamieson, Peter McKeich; Hornzee-Jones, Chris; Moroz, Emilian M.; ...

A system and method for changing wind turbine rotor diameters to meet changing wind speeds and control system loads is disclosed. The rotor blades on the wind turbine are able to adjust length by extensions nested within or containing the base blade. The blades can have more than one extension in a variety of configurations. A cable winching system, a hydraulic system, a pneumatic system, inflatable or elastic extensions, and a spring-loaded jack knife deployment are some of the methods of adjustment. The extension is also protected from lightning by a grounding system.
