Abstract: A platform seal assembly for a gas turbine engine with a turbine disk and a plurality of turbine blades is disclosed. The platform seal assembly includes a platform seal and a validation tab. The platform seal includes a first end, a second end, opposite and distal to the first end, and a body extending between the first end and the second end. The validation tab includes an attachment portion affixed to the platform seal and an observable indicator portion extending from the attachment portion.

Abstract: A method for designing a component for a circumferential machine is disclosed. The method includes selecting one or more seed nodes, creating a cylindrical coordinate system, and selecting an output subset. The method further includes creating a node set from the one or more seed nodes based on a selected feature of the component to be analyzed. The method yet further includes extracting an output for the node set from the finite element analysis module for each load cycle and presenting a result from the extracted output.

Abstract: A component for a gas turbine engine is disclosed. The component includes at least a first portion and a second portion, and a data representing matrix. The second portion includes a second portion surface. The data representing matrix is formed directly on the second portion surface and includes a plurality of contrasting cells arranged in a geometric pattern representing information about the component including test data, a serial number, and a part number. The plurality of contrasting cells includes a plurality of first cells and a plurality of second cells that contrast from the plurality of first cells.

Abstract: A gas turbine engine turbine disk assembly includes a turbine disk, turbine blades, and pin seals. Each turbine blade includes a platform with a pressure side seal slot extending into a pressure side of the platform and a suction side seal slot extending into a suction side of the platform. The pressure side seal slot and the suction side seal slot are each angled between three and ten degrees in the radial direction relative to the axis of the turbine disk. The pin seal includes a cylindrical shape and is located within a seal slot formed from the pressure side seal slot and the suction side seal slot of adjacent turbine blades.

Abstract: A walking sole which enables a person wearing in-line skates to walk freely. The walking sole includes a U-shaped member having a longitudinal trough into which a skate's wheels are inserted, and two slidably adjustable alignment posts which are brought into pressing contact with the outer wheels. Each post is securely fixed to the base of the U-shaped member by interfacing corrugations in its bottom surface with corrugations in the base upper surface before connecting the post and base with a bolt.

Abstract: An in-line skate with an attached walker that is pivotable securely downward to interpose a flat walking surface between the skate wheels and ground, and pivotable securely upward away from the wheels and skate undercarriage so as not to interfere with skating. The walker includes a first flange bolted to the undercarriage and hingeably connected to an angle member having a second flange integral with a third flange to which is attached a walking sole. In a first embodiment the sole is attached to an angle member third flange by a plurality of rivets. In a second embodiment the sole is adhesively attached to the angle member third flange.
