Abstract: A ram air turbine power system is provided with a deployable ram air turbine mounted in-line with a power supply unit such as an electrical generator and/or an hydraulic pump. The ram air turbine includes a turbine shaft supported for rotation by bearings within a generator housing, wherein a rear end of the turbine shaft and a generator shaft are supported by a common bearing, and further wherein the forwards ends of the turbine and generator shafts are supported by a pair of bearings separated by a resilient bearing mount. In addition, the in-line ram air turbine and related power supply unit are supported from a hollow strut with hydraulic and electrical lines and related mechanical linkages extending therethrough.
