A ram air turbine (RAT) system can include a fluid circuit, a turbine, a shaft connected to the turbine to turn with the turbine, and a hydraulic pump connected (e.g., directly) to the shaft and connected to the fluid circuit to pump fluid within the fluid circuit. The hydraulic pump can be a variable displacement pump, for example (e.g., configured to govern a speed of the shaft and turbine). The hydraulic pump can be used to power and provide speed control to an electric generator.
