초록

A method of starting a gas turbine engine eliminating the need for oversizing a starter motor or the like to attain a proper transition through the “pinch point”includes the steps of applying a torque from an external source to the gas turbine engine (10) to accelerate the same toward a self sustaining speed, igniting fuel in the engine (10) at a pre-determined speed less than the self-sustaining speed, and at or about the time of fuel ignition, momentarily increasing the torque applied to accelerate the engine (10). The acceleration torque and momentary...
