    Abstract: A control system for turbofan engine includes a first sensor measuring rotation of a first shaft at a first location and a fan shaft sensor measuring a speed of a fan shaft. A controller utilizes measurements of a first speed of the first shaft from the first sensor and a second speed of the fan shaft driven by a geared architecture and rotating at a speed different than the first shaft. The controller determines that one of the first shaft and the fan shaft are outside predetermined deformation limits responsive to a difference between an actual difference between the first and second speeds and a calculated expected difference between speeds of the first shaft and the fan shaft.

    Abstract: An ongoing issue for gas turbine engines is the ease and speed at which certain components in such engines can be served. Engine architectures may be designed to facilitate access to internal engine components. One such engine architecture may include a central body support that provides an inner annular wall for a core flow path. The central body support includes first splines. A geared architecture interconnects a spool and a fan rotatable about an axis. A flex support interconnects the geared architecture to the central body support. The flex support includes second splines that intermesh with the first splines for transferring torque there between.

    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.
