A baffle component for a turbine starter includes a first baffle level and a second baffle level stacked with the first baffle level. The first baffle level and the second baffle level may be arranged with a starter assembly such that airflow entering the baffle levels is directed by the first baffle level and the second baffle level to exit the starter assembly.

A standpipe assembly configured to connect to a starter that includes a housing is described herein. The standpipe assembly includes: a standpipe having first and second openings at opposite ends of a hollow passageway, wherein the standpipe, upon being connected to the starter, is oriented within the housing so that the standpipe drains oil through the standpipe when oil in the housing reaches an overfill level, and is oriented in parallel to internal oil flow in the starter to inhibit interference with the internal oil flow during operation of the starter; and an attachment portion, wherein the attachment portion is structured to attach the standpipe assembly to the housing of the starter and prevent movement of the standpipe assembly with respect to the housing of the starter.

An impeller includes a body with an interior channel extending through the body along a centerline axis of the impeller. A plurality of blades is connected to the body on a forward end of the impeller centerline axis. The plurality of blades surrounds the interior channel and is fluidly connected to an array of inlets. An array of pentagonal channels extends through the body and radially outward in a spiral pattern. Each pentagonal channel is fluidly connected to a corresponding vane inlet and a corresponding pentagonal-shaped outlet. Each channel maintains a pentagonal cross-section shape from the inlet to the outlet. Each downward-sloping face of the cross section is more than 35 degrees from a horizontal plane perpendicular to the centerline axis of the impeller.
