Abstract:
1. A ram air turbine generator for an aircraft comprising: a mounting plate configured to close a first end of a generator housing and mount to a pylon extendable from an aircraft; a first shaft fixedly mounted to the mounting plate; a stator fixedly mounted to the first shaft and having multiple windings; a rotor housing rotatably mounted to the first shaft and at least partially encasing the stator; multiple axially-oriented, permanent magnets, each defining a pole of the rotor and mounted to an inner surface of the rotor housing in an orientation substantially parallel to the first shaft; and a propeller operably coupled to the rotor housing via a second shaft and having multiple blades; wherein air flowing over the blades rotates the propeller to rotate the second shaft, which rotates the rotor housing and permanent magnets about the multiple windings to generate an electric current in the windings.
