Abstract:
A gas turbine engine has a fan drive turbine for driving a gear reduction. The gear reduction drives a fan rotor. A lubrication system supplies oil to the gear reduction, and includes a lubricant pump to supply an air/oil mixture to an inlet of a deaerator. The deaerator includes a separator for separating oil and air, delivering separated air to an air outlet, and delivering separated oil back into an oil tank. The separated oil is first delivered into a pipe outwardly of the oil tank, and then into a location beneath a minimum oil level in the tank. Air within the oil tank moves outwardly through an air exit into the deaerator. A method of designing a gas turbine engine is also disclosed.

Claim (Index 16):
A method of designing a gas turbine engine comprising:\n providing a fan drive turbine for driving a gear reduction, said gear reduction for driving a fan rotor; and providing a lubrication system for supplying oil to said gear reduction, with an oil tank, the lubrication system including a lubricant pump; and supplying an air/oil mixture to an inlet of a deaerator, said deaerator including a separator for:\n separating oil and air, \n delivering separated air to an air outlet, and \n delivering separated oil back into an oil tank, \n wherein said separated oil is first delivered into a pipe outwardly of the oil tank, and then into a location beneath a minimum oil level in the tank, wherein air within the oil tank moves outwardly through an air exit into the deaerator, and an exit velocity from the deaerator of the separated air is less than or equal to 14 feet/second.
