초록

For gas turbine engine mounted in an aircraft, a closed loop control system, and method therefor, for the inlet duct is provided. Under this control system the flow area of the inlet duct is varied by opening and closing a duct door. The control assures that the position of the door is such that the delta P across the engine will not inhibit the starting of the engine in flight.

청구항

[ What is claimed is:] [1.]1. A method for controlling the delta P across a gas turbine engine disposed in a movable body having an inlet duct extending from a surface of said body to an inlet of said gas turbine engine, said duct having a variable flow area positionable continuously between a fully open position and a closed position, comprising the steps of:sensing at least one parameter indicative of the engine's operating condition and generating a signal indicative thereof;receiving said sensing signal and generating a signal indicative of a predete...
