ABSTRACT:
An anti-icing management system for a gas turbine engine according to which, at all times, only the required amount of heat is applied to inlet surfaces of the engine to prevent the formation of ice. Heated air is bled from the compressor discharge, or from some other suitable heat source, for this purpose. The amount of flow of the heated air is adjusted by an electronic control responsive to the temperature of the anti-iced engine inlet surfaces directly in the path of incoming air. The electronic control may be effective to admit flow of the heated air to the region to be heated when a separate ice detector determines the presence of ice and so informs the control.
