Abstract:
A pressure fed oil drain for gas turbine engine (10) includes an oil sump (48) and a passage (60, 63) in selective flow communication with the oil sump (48), the passage in flow communication with a drain (62), the passage being pressurized and creating a differential between the passage and ambient atmosphere (65), the drain is disposed at an elevation beneath a passage feature (64) when the turbine engine is disposed at an extreme attitude angle, the passage (63) extending upwardly when in the extreme attitude angle.
