  • Ram air turbine system
    Patent number: 6127758
    Abstract: A ram air turbine includes a reaction turbine and an electrical generator that is driven by shaft power of the reaction turbine. A scoop directs a flow of ram air to an inlet of the reaction turbine and creates a pressure head for the reaction turbine. The reaction turbine and the scoop are contained entirely within a pod. The ram air turbine further includes a turbocompressor, including a turbine stage and a compressor stage, which provides a stream of cooled air to equipment inside the pod. The turbocompressor also reacts loads shed by the electrical generator.
