초록

A geared turbofan gas turbine engine has a fan rotor carrying a plurality of fan blades driven by a gas generator via a gear assembly. A fan casing which has an exterior surface is positioned coaxially with and encloses the fan rotor. A lubricant supply is provided to lubricate and cool the gear assembly and a heat exchanger is provided to cool the lubricant. An air scoop forms a first duct which supplies air to the heat exchanger to cool the lubricant. A second duct defined partially by the air scoop downstream of the heat exchanger and an annular chamb...
