Abstract: An oil supply system for an aircraft engine having a rotating shaft comprises a retaining nut including a unitary annular body having an outer surface and an inner surface extending around a central axis between a first end and a second end. The inner surface has a threaded portion at the second end. The threaded portion is configured for threaded engagement with a corresponding threaded portion of the rotating shaft. The outer surface of the unitary annular body includes a series of teeth distributed around the central axis of the retaining nut. The teeth are configured for engagement with a tightening tool. A first tooth of the teeth has a first radial oil scoop formed thereon. The first radial oil scoop defines an oil passage extending from the outer surface to the inner surface of the nut at an axial location between the first end and the threaded portion.

Abstract: An apparatus includes a display, memory, and processor. The memory stores information associated with subaccounts of an account. The processor receives a request to display the information. The processor displays a table that includes the names of the subaccounts, premium payment allocation amounts assigned to the subaccounts, and values of the subaccounts. The processor displays a graphical illustration associated with the account, that includes a first set of sections associated with the allocation amounts and/or a second set of sections associated with the values. Each section defines an area on the display that is proportional to the corresponding allocation amount or value. The processor further receives an indication associated with one of the subaccounts. In response, the processor emphasizes the row of the table and at least one of the sections assigned to the subaccount.

Abstract: An unbalanced rotor is provided to perform unbalance testing on an aircraft power plant. The unbalanced rotor includes a hollow body rotatable about a rotation axis and an unbalancing weight installed inside of the hollow body. The unbalancing weight is installed inside of the hollow body to intentionally vibrate the rotor during rotation of the rotor. The unbalancing weight is fastened to the hollow body via one or more fasteners. A portion of the unbalancing weight is disposed radially inwardly of a retainer of the hollow body and is engaged with the retainer to define a radial load path between the unbalancing weight and the hollow body via the retainer. The radial load path excludes the one or more fasteners.

Abstract: A platen assembly for use with an extrusion-based 3D printer includes a grid assembly comprising at least a 4×2 framework of interlocked perpendicular x direction beams and y direction beams, providing a substantially planar upper surface and a bottom surface. The platen assembly includes a platen comprising a thin metal sheet supported on the upper surface of the grid assembly and secured to the grid assembly such that the top surface provides a substantially flat build surface. The x direction beams, the y direction beams and the platen are constructed of substantially a same thermal expansion properties, and wherein the build surface of the platen has a build surface area of at least 400 square inches and maintains its flatness to within a flatness tolerance of 0.020 inches over a temperature range of at least 20 C-300 C.
