Abstract: A seal assembly for a rotary machine. The seal assembly includes a rotor and a stator. The rotor is rotatable about a rotational axis and has a rotor seal face. The stator has a stator seal face. The stator seal face is positioned opposite the rotor seal face and faces the rotor seal face with a gap therebetween. A portion of one of the rotor and the stator is formed of (i) a shape memory alloy or (ii) a first metal and a second metal with the second metal having a coefficient of thermal expansion different from the first metal. The seal assembly is characterized by a seal clearance compliance ratio (SCCR) from 20% to 90%.

Abstract: A bearing assembly includes a bearing, an outer race located radially outward of the bearing and supporting the bearing, a bearing housing located radially outward of the outer race and supporting the bearing and the outer race, and a bearing lubricant drain including a multi-directional passage formed in one or both of the outer race or the bearing housing, the lubricant drain arranged to cause a lubricant to flow from a first location to a second location. The second location is radially outward and axially offset from the first location. A gas turbine engine includes a shaft configured to rotate about a centerline axis of the gas turbine engine and the bearing assembly configured to facilitate the rotation of the shaft.
