Abstract: Oil sump seal pressurization apparatus for a turbine engine are disclosed. An example oil sump seal pressurization apparatus may include an oil sump comprising at least one bearing mounted therein; an oil seal operatively disposed between a non-rotating structural member of the sump and the shaft; a generally radially inwardly oriented passage arranged to supply pressurization air to the outward side of the oil seal; a generally radially outwardly oriented pathway arranged to receive at least some of the pressurization air from the passage, the pathway being at least partially defined by a generally radially outwardly extending arm disposed on the shaft, the arm rotating with the shaft; and/or a windage shield at least partially separating the passage and the pathway, the windage shield being operatively mounted to the non-rotating structural member of the sump.

Abstract: Oil sump seal pressurization apparatus for turbine engines are disclosed. An example oil sump seal pressurization apparatus may include a non-rotating oil sump housing a bearing; an oil seal isolating an interior of the oil sump; a passage arranged to supply pressurization air to an outward side of the oil seal; a drain arranged to allow draining of oil and venting of at least some of the pressurization air, the drain being positioned axially between the passage and the oil seal; a wide discourager tooth disposed on the shaft and extending radially outward towards a non-rotating land, which may be disposed axially between the passage and the drain, the wide discourager tooth being spaced apart from the land in a radial direction by a gap, the wide discourager tooth including an upper surface; and/or an adjacent tooth disposed on the shaft and extending radially outward from the shaft.

Abstract: An air/oil separator for a gas turbine engine includes a drive shaft having a central axis extending in an axial direction, a free vortex chamber mounted radially around the drive shaft, a separation chamber coupled with the free vortex chamber in the axial direction opposite to the drive shaft, and a rotatable outlet shaft radially rotatable and having an inlet end coupled with the separation chamber opposite to the free vortex chamber, an outlet end, and a hollow interior chamber therebetween. The hollow interior chamber has an inner circumference extending in the axial direction a cylindrical air guide extending coaxially therein. The cylindrical air guide has a nonporous cylindrical main body, an upstream end fixedly coupled with the inlet end of the rotatable outlet shaft, and a downstream end coaxially disposed within the outlet end of the rotatable outlet shaft.

Abstract: A high pressure BLISK includes at least one circular row of airfoils circumferentially disposed about, integral with, and extending radially outwardly from an annular rim having an annular flat aft facing face with coplanar radially outer and inner face portions radially separated by an annular undercut extending into the rim from the aft facing face. Airfoil roots including root fillets extend around the airfoil between the rim and pressure and suction sides of the airfoils. An axially aftwardly extending annular cylindrical section extends aftwardly from the flat face. The BLISK being a first of axially adjacent first and second rotor sections connected by a rabbet joint. A forward arm of the second rotor section includes an outer forward facing annular face spaced apart from the aft facing face radially outwardly of the annular undercut and a radially inner forward facing annular face contacting the aft facing face.

Abstract: A flow vortex spoiler including an oil sump wherein pressurization air flow moves about the oil sump through a sump pressurization cavity, the cavity having an inlet, a circumferential plate disposed across a portion of the pressurization cavity near the inlet. The circumferential plate is disposed at said inlet to said sump pressurization cavity. The circumferential plate has a plurality of closely spaced apertures. The pressurization air has a radial component and a tangential component wherein the circumferential plate and the plurality of closely spaced apertures substantially reduce the tangential component of the pressurization air and further wherein the vortex spoiler inhibits excessive pressure change within the pressurization cavity and inhibits oil leakage at seals adjacent to the oil sump.
