Beschreibung
Zusammenfassung:	A rotary actuator for control of variable geometry vanes is provided. The actuator is rotary so that operating components are internalized to protect fuel from contamination. The rotary actuator is a self-contained unit so that the device may be removed from the gas turbine engine without requiring removal of additional fuel system components. Finally, some embodiments of the rotary actuator may comprise multiple actuator loops to provide adjustment for two or more rows of vanes, independently.
