    摘要： A gearbox assembly includes a gearbox housing and a gear located in the housing and rotatable about a central axis. One or more gear shields are fixed in the housing and at least partially surround the gear. The one or more gear shields define a cavity between the gear and the one or more gear shields. The one or more gear shields are configured such that a pumping action is created by the gear rotation to direct gearbox lubricant out of the cavity. A method of scavenging lubricant from a gearbox includes pumping a flow of lubricant circumferentially around a cavity defined between a gear and a gear shield at least partially surrounding the gear via rotation of the gear about a central axis. The flow of lubricant is urged from the cavity into a lubricant outlet. The lubricant is urged through a lubricant channel in an axial direction.

    摘要： A casing 132 for use in a turbofan engine 100 is provided. The casing 132 includes an inner hub 134 including a first fluid opening 140 defined at bottom dead center of the casing 132. The casing 132 also includes an intermediate casing 136 positioned radially outward from the inner hub 134, an outer casing 138 positioned radially outward from the intermediate casing 136, and struts spaced circumferentially about the inner hub 134 and extending between the inner hub 134 and the outer casing 138. The struts include a first strut 144 and a second strut 146 positioned on opposing sides of bottom dead center of the casing 132 such that a first fluid sump 148 is defined between the inner hub 134, the intermediate casing 136, and the first and second struts 144,146. At least one of said first and second struts 144,146 includes a flow channel 150,152 extending therethrough such that a fluid flow path is defined from the first fluid opening 140, through the first fluid sump 148, and through the flow channel 150,152.
