摘要： A forward mount assembly for connecting a pylon to an intermediate case of a gas turbine engine, the forward mount assembly includes a forward mount platform, a wiffle tree assembly, and first and second A-arms. The platform is connected to the pylon and is disposed adjacent the intermediate case. The wiffle tree assembly is connected to the forward mount platform through a first ball joint. The first A-arm is connected to a first side of the intermediate case and the second A-arm is connected to a second opposing side of the intermediate case. The first and second A-arms are mounted to the forward mount platform and are mounted to opposing ends of the wiffle tree. The aforementioned arrangement allows the first and second A-arms to react a thrust load at the intermediate case substantially parallel to a centerline axis of the gas turbine engine.

摘要： A gas turbine engine includes a spool, a gearbox having gearing driven by the spool, and a lubrication system. The lubrication system includes a first heat exchanger positioned in a first air flow path, a second heat exchanger positioned in a second air flow path, and a lubrication pump fluidically connected to both the first heat exchanger and the second heat exchanger. A first air fan is driven by the gearbox for inducing air flow through the first air flow path. A second air fan is driven by an electric motor for inducing air flow through the second air flow path.

摘要： A gas turbine engine includes a low pressure compressor section and a high pressure compressor section. A low pressure turbine drives the low pressure compressor section. A gear arrangement is driven by the low pressure turbine to in turn drive a fan section. A pressure ratio across the low pressure compressor section is between about 4-8, and a pressure ratio across the high pressure compressor section is between about 8-15. In a separate feature, a compressor case includes a front compressor case portion and a rear compressor case portion, with the rear compressor case portion being axially further from an inlet case than the front compressor case portion. A support member extends between the fan section and the front compressor case portion.
