Patent number: 8910463Abstract: A cooling system for turbine starter lubricant includes one or more outflow transfer passages (54) extending from the turbine starter (10) to a secondary component (40). At least one heat exchange passage (56) affixed at a first end to an end of an outflow transfer passage (54) of the one or more outflow transfer passages (54), is located in the secondary component (40) having a lower interior temperature than the turbine starter (10). One or more return transfer passages (60) are affixed to a second end of the at least one heat exchange passage (56) and extend from the secondary component (40) to the turbine starter (10). Flowing a volume of starter lubricant (42) through the one or more outflow transfer passages (54), the at least one heat exchange passage (56), and the one or more return transfer passages (60) removes thermal energy from the volume of starter lubricant (42) and returns the volume of starter lubricant (42) to the turbine starter (10).Type: GrantFiled: February 22, 2010Date of Patent: December 16, 2014Assignee: Hamilton Sundstrand CorporationInventor: Robert Telakowski

Publication number: 20140284038Abstract: A method of forming a heat exchanger for use with a rotating component configured to rotate about an axis of rotation is provided including generating a stereolithography file of the surface geometry of the heat exchanger. The surface geometry of the heat exchanger includes a cylindrical base having a plurality of fins extending generally radially therefrom. The surface geometry defined in the stereolithography file is ‘sliced’ into a plurality of axisymmetric layers, perpendicular to the axis of rotation. Energy from an energy source is applied to a powdered material causing the powdered material to fuse and form the plurality of axisymmetric thin layers. Each of the axisymmetric thin layers is integrally formed with an adjacent axisymmetric thin layer to create a unitary heat exchanger.Type: ApplicationFiled: March 21, 2013Publication date: September 25, 2014Applicant: HAMILTON SUNDSTRAND CORPORATIONInventors: Venkata R.
