摘要： A gas turbine engine includes a central body support that provides an inner annular wall for a core flow path. The central body support includes a first mount feature. 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 a second mount feature that cooperates with the first mount feature for transferring torque there between. A method of disassembling a front architecture of a gas turbine engine includes the steps of accessing forward-facing fasteners that secure a central body support to a flex support, wherein the flex support includes a geared architecture supported thereon, removing the fasteners, and decoupling first and second mount features respectively provided on the central body support and the flex support.

摘要： The present disclosure is directed to lubrication systems for gear systems of a gas turbine engine. In one embodiment, a lubrication system includes an auxiliary reservoir configured to store lubricant and a lubrication collection device. The auxiliary reservoir is contained within an annular structure of the gas turbine engine. The lubricant collection device can collect lubricant from a gear system of the gas turbine engine and direct collected lubricant to the auxiliary reservoir. The auxiliary reservoir is configured to receive collected lubricant by way of a channel within the annular structure. The lubrication system may compliment a main lubrication system, and in particular, when the main lubrication system is temporarily unable to supply lubricant to the gear system.
