Title
(EN) Nacelle anti-ice valve utilized as compressor stability bleed valve during starting
front page image
Abstract
(EN)

A gas turbine engine has a compressor section received within an inner housing. An is an outer housing is spaced radially outwardly of the inner core housing. A nacelle has an anti-icing system which taps compressed air from the compressor section through an anti-ice valve and to the nacelle. The anti-ice valve is opened at startup of the gas turbine engine to assist compressor stability.
