Abstract: A lubricant manifold for gear system of a turbofan engine includes a base plate defining an inlet, an outlet and a plurality of open channels. The open channels define a portion of a corresponding plurality of lubricant passages. A cover plate is attached to the base plate to complete the formation of the plurality of lubricant passages. An interlocking interface between the base plate and the cover plate secures the cover plate to the base plate.

Abstract: A lubrication system for gas turbine engine includes a main lubricant passage for providing lubricant from a lubricant supply to a lubricant manifold. The lubricant manifold includes first and second lubricant passages The lubricant manifold is configured to supply lubricant to first and second separate parts of a geared architecture at different first and second lubricant flow conditions. A first filter element is provided within a radial tube for supplying lubricant to the first passage of the lubricant manifold and a second filter element is provided within a second radial tube for supplying lubricant to the second lubricant passage of the lubricant manifold. The first filter element is different than the second filter element.
