Abstract
A gas turbine engine comprised of a gas generator in flow series arrangement with a free turbine is provided, that includes a bleed port disposed between the gas generator and the free turbine. The flow of hot gas through the free turbine is controlled by a valve operably disposed in a duct downstream of the bleed port. The gas turbine engine can rapidly change its power output by first bleeding a portion of the hot gas exiting the gas generator overboard, and then increasing or decreasing the amount of bleed flow, thereby producing rapid changes in the free turbine's output.
