Yaw

energy

The movement of the tower top turbine that allows the turbine to stay into the wind.

Yaw angle

energy

The angle between a line in the direction of wind and a plane through the longitudinal and vertical axes of a turbine.

Yaw drive

energy

To ensure the wind turbine is producing the maximum amount of electric energy at all times, the yaw drive is used to keep the rotor facing into the wind as the wind direction changes.

Yaw motor

energy

A yaw motor powers the yaw drive.

Yaw, yawing

Yellowcake

energy

Yellowcake is a type of uranium concentrate powder obtained from leach solutions, in an intermediate step in the processing of uranium ores.

Yield point

energy

Yield point is the point on a stress-strain curve that indicates the limit of elastic behavior and the beginning of plastic behavior.

Yield strength

energy

The yield strength or yield stress is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically.

Yoke arm

marine

A structure at the end of the vessel that allows only angular relative movement between the vessel and the mooring attachment to the seabed.

Young's modulus

energy
