1. A turbine starter assembly comprising:
a turbine starter extending along a central axis;
an exhaust baffle component connected to the turbine starter, the exhaust baffle component comprising:
a plurality of frames arranged with one another as a single component,
wherein each of the plurality of frames is connected to at least two adjacent frames of the plurality of frames to define a substantially circular shape about the central axis and to define a centerline that is parallel to the central axis;
each of the plurality of frames includes:
an upper portion and a lower portion that are spaced apart from each other along the central axis, wherein the upper portion of the frame includes two louvers stacked relative to one another and spaced from one another along the central axis to define an air opening therebetween, wherein each of the louvers extend, end to end, in a circumferential direction about the central axis;
an attachment flange, extending along a flange axis from the upper portion toward the central axis to a radial inner end of the attachment flange, wherein the flange axis is perpendicular to the central axis, and wherein the attachment flange defines a receiving aperture oriented parallel to the central axis,
wherein the receiving aperture is aligned with a starter aperture of a starter component of the turbine starter to facilitate securement of the attachment flange to the starter component; and
an extension, configured to engage a housing of the starter component, extending from the lower portion of the frame along an extension axis that is parallel to the flange axis for the frame and extends toward the central axis to a radial inner end of the extension,
wherein the extension defines openings that are adjacent to each other and to the lower portion of the frame;
wherein each frame defines a U-shaped profile including the attachment flange and the extension flange.
