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.
