Abstract
An oil scavenge system includes a scavenge pipe which extends forward into a relatively long and narrow compartment area of a rear bearing compartment of a gas turbine engine with aggressive core size constraints. The scavenger pipe communicates collected oil to a scavenger pump to return oil to the oil sump and evacuate the oil before flooding of the seals may occur.
