Abstract
A turbine engine system includes a gutter and a gear train with an axial centerline. The gutter is disposed radially outside of the axial centerline. The gutter includes an inner surface and a channel that receives fluid directed out of the gear train. The inner surface at least partially defines a bore in which the gear train is arranged. The channel extends radially into the gutter from the inner surface, and circumferentially to a channel outlet. The bore has a cross-sectional bore area, and the channel has a cross-sectional channel area that is substantially equal to or less than about two percent of the bore area.

A turbine engine system, comprising:
- a gear train with an axial centerline;
- and
- a gutter at least partially circumscribing the gear train;
- the gutter including an inner surface and a channel;
- the channel configured to receive fluid directed out of the gear train;
- the channel extending radially into the gutter from the inner surface;
- and
- the channel extending circumferentially to a channel outlet;
- wherein the inner surface has a surface radius, and the channel has a radially extending channel height that is equal to or less than eight percent of the surface radius.
