A ram air turbine (RAT) assembly includes a gearbox that supports a gear set with a ring gear that drives a pinion gear. The gear set provides for the transmission of power from the turbine to a generator, pump or other power conversion device. A turbine shaft supports the ring gear and a pinion shaft that rotates about an axis transverse to the turbine shaft supports the pinion gear. A ratio between a face width and a diametrical pitch of the gear set is within a desired ratio that provides sufficient space for supporting bearing assemblies while providing for operation within the physical constraints and desired performance requirements of the RAT.

A wind turbine rotor includes a hub, a plurality of blades, and a pitch system for rotating a blade substantially along its longitudinal axis. The pitch system includes a bearing, a motor, and a gear system, wherein the gear system has a driving pinion operationally connected with the motor, an annular gear arranged to mesh with the driving pinion. Additional gear teeth are arranged to mesh with other parts of the gear system in a predefined blade position for wind speeds at or below a nominal wind speed such that upon movement from the predefined blade position, the additional gear teeth come into contact with the other parts of the gear system before the driving pinion comes into contact with the annular gear.

A vertical turbine comprising a blade control mechanism including a sun gear engaging a plurality of planetary gears each coupled to blade assemblies. The sun gear has at least half circumference of its teeth removed, as the turbine receives maximum downstream torque in the circumference with teeth and it leaves blades free to rotate in the circumference without teeth for minimum upstream drag. The turbine converts the rotational blades into parallel movement and unidirectional propulsion with minimum turbulence.
