Abstract
A gas turbine engine with a lubrication system includes a ball bearing assembly and a rotor circumscribing a rotational axis and journaled within the ball bearing assembly. The gas turbine engine also includes a lubrication system located radially outward from a rotational axis and radially outward and adjacent to the ball bearing assembly, which includes a lubrication channel having an inlet and an outlet and a dispersion cone adjacent to the outlet of the lubrication channel.

A gas turbine engine, the gas turbine engine comprising:
- a ball bearing assembly;
- a rotor circumscribing a rotational axis and journaled within the ball bearing assembly;
- and
- a lubrication system located radially outward from the rotational axis and radially outward and adjacent to the ball bearing assembly, the lubrication system comprising:
- a lubrication channel having an inlet and an outlet;
- and
- a dispersion cone adjacent to the outlet of the lubrication channel, wherein the dispersion cone comprises at least one airfoil shaped spar on an interior of the dispersion cone, the at least one airfoil shaped spar is integral to the dispersion cone, and the at least one airfoil shaped spar is configured to increase dispersion of a lubricant traveling through the dispersion cone.
A method of manufacturing a gas turbine engine, the method comprising:
- journaling a rotor within a ball bearing assembly and the rotor circumscribing a rotational axis;
- and
- additively manufacturing a lubrication system located radially outward from the rotational axis and radially outward and adjacent to the ball bearing assembly, the lubrication system comprising:
- a lubrication channel having an inlet and an outlet;
- and
- a dispersion cone adjacent to the outlet of the lubrication channel, wherein the dispersion cone comprises at least one airfoil shaped spar on an interior of the dispersion cone, the at least one airfoil shaped spar is integral to the dispersion cone, and the at least one airfoil shaped spar is configured to increase dispersion of a lubricant traveling through the dispersion cone.
