GAS TURBINE ENGINE INCLUDING A LOW PRESSURE SUMP SEAL BUFFER SOURCE AND THERMALLY ISOLATED SUMP
摘要
A gas turbine engine is configured to use relatively cool, low pressure air discharged from a low pressure compressor to supply buffer air to lubrication sump seals. The engine is further configured such that the lubrication sump is thermally layered by isolating relatively hot, high pressure compressor air from the sump by utilizing a warm vent mixing cavity, which is located radially between of the hot high pressure compressor air and the cool buffer air, which is located in a buffer cavity between the vent cavity and the sump.
