Abstract
A ram air turbine power system includes a ram air turbine having a turbine shaft, turbine blades for rotating the turbine shaft; and an electrical generator or other power source device driven by a power shaft, for providing power. The power shaft has a generally hollow tubular shape, and the turbine shaft extends coaxially within the power shaft. The ram air turbine power system also includes a gearbox housing a planetary gear train, where one end of the gear train is a planetary sun gear spline coupled to the power shaft and the other end of the gear train is a planetary ring gear spline coupled to the turbine shaft so that the rotating turbine shaft drives the power shaft through the gear train increasing the speed of the power shaft over the speed of the turbine shaft.
