Abstract
A power turbine speed control system for a turbo-shaft type gas turbine engine that has a gas generator compressor spool and a power turbine spool and drives an electrical generator that powers at least one electrical load by way of at least one electrical bus, comprises a power turbine controller that senses the rotary speed of the power turbine spool and generates at least one signal that changes the torque of the electrical generator in response to the sensed change in the rotary speed of the power turbine spool.
