A combustor nozzle includes a nozzle body that defines a cavity. An orifice in the nozzle body provides fluid communication from the cavity through the nozzle body. A movable barrier proximate to the orifice has a first position in which the movable barrier at least partially obstructs the orifice. A method for supplying fuel to a combustor includes flowing fuel through an orifice in a nozzle, determining a reactivity of the fuel, and adjusting an effective cross sectional area of the orifice based on the reactivity of the fuel.

The machine includes a rotor with an inner rotor core and an outer rotor core and a double-sided stator with an inner stator side and an outer stator side. The double-sided stator is concentrically disposed between the inner rotor core and the outer rotor core of the wind turbine generator. The double-sided stator is configured to enable at least a portion of magnetic flux to be shared between the inner stator side and the outer stator side. Examples of particularly useful embodiments for the machine include wind turbine generators and ship propulsion motors.

An electrical machine stator is disclosed that includes a stack of laminations configured to be assembled together so as to define at least one stator tooth. The stack of laminations may include a plurality of nesting laminations and a plurality of shim laminations. Each nesting lamination may include a first edge section, a second edge section and a middle section extending between the first and second edge sections. At least one of the first edge section and the second edge section of each nesting lamination may be configured to be engaged against at least one of the first edge section and the second edge section of an adjacent nesting lamination when the stack of laminations is assembled together. Additionally, at least one shim lamination may be disposed between each pair of adjacent nesting laminations.

In one aspect, a system for detecting loads transmitted through a blade root of a rotor blade of a wind turbine is disclosed. The system may include a root attachment assembly configured to couple the blade root to a hub of the wind turbine. The root attachment assembly may include a barrel nut mounted within a portion of the blade root and a root bolt extending from the barrel nut. In addition, the system may include a sensor associated with the root attachment assembly. The sensor may be configured to detect loads transmitted through at least one of the barrel nut and the root bolt.

A wind turbine rotor blade assembly includes a rotor blade having a pressure side, a suction side, a leading edge, and a trailing edge extending in a generally span-wise direction between a tip and a root. An edge extension is attached along the trailing edge and includes a first strip member having a span-wise attachment section attached to pressure side, and a second strip member having a span-wise attachment section attached to the suction side. Each of the first and second strip members has an outboard edge and an extension section that projects chord-wise beyond the trailing edge. The extension sections are adhesively attached to each other outboard of the trailing edge along a span-wise length of the first and second strip members and define an adhesively bonded closure edge of the edge extension. A method is also provided for forming an edge extension on a wind turbine rotor blade.

An electrical machine stator is disclosed that includes a stack of laminations configured to be assembled together so as to define at least one stator tooth. Each lamination may include an inner edge, an outer edge and first and second side edges extending at least partially between the inner and outer edges so as to define at least a portion of the at least one tooth. Additionally, each lamination may define a nesting feature between the first and second side edges, wherein the nesting feature of each lamination is engaged against the nesting feature of an adjacent lamination when the stack of laminations is assembled together.

A wind generator includes: a nacelle; a hub carried by the nacelle and including at least a pair of wind turbine blades; and an electricity producing generator including a stator and a rotor carried by the nacelle. The rotor is connected to the hub and rotatable in response to wind acting on the blades to rotate the rotor relative to the stator to generate electricity. A cooling system is carried by the nacelle and includes at least one ambient air inlet port opening through a surface of the nacelle downstream of the hub and blades, and a duct for flowing air from the inlet port in a generally upstream direction toward the hub and in cooling relation to the stator.
