Gas turbine engine comprising a nacelle compartment plenum for bleed air flow delivery system

摘要

A gas turbine engine (10) is provided with a nacelle (100) having a hollow inner space (120). The inner space (120) is utilized as a plenum for directing air from an inlet (116) to an outlet (104) at the upstream end (99) of the nacelle (100) to allow control of an effective lip width of the nacelle (100) under certain flight conditions.
