Abstract: A stator assembly, in accordance with various embodiments, is disclosed herein. The stator assembly comprises either a first bumper or a first tab. The first bumper or the first tab extends circumferentially outward from a mating portion of the vane towards a slot in a ring. The ring may be an outer diameter (OD) ring or an inner diameter (ID) ring. The mating portion of the vane may be coupled to the ring by a potting component. The potting component may prevent direct contact between the vane and the ring.

Abstract: A method is provided for inspecting a device comprising a plurality of bristles. During this method, image data provided from an electronic optical sensor is received. The image data is indicative of an image of at least a portion of the bristles. A bristle configuration (e.g., an angle) of at least one of the bristles (e.g., an average bristle) in the image is determined by processing the image data with a computer processor.

Abstract: An active clearance control system of a gas turbine engine includes a multiple of blade outer air seal assemblies and a multiple of rotary ramps. Each of the multiple of rotary ramps is associated with one of the multiple of blade outer air seal assemblies. A method of active blade tip clearance control for a gas turbine engine is provided. The method includes rotating a multiple of rotary ramps to control a continuously adjustable radial position for each of a respective multiple of blade outer air seal assemblies.

Abstract: A method of actuating a Blade Outer Air Seal (BOAS) includes moving a retractor against a portion of a BOAS segment to move the BOAS segment from a first position to a second position that is radially outside the first position. The BOAS segment is seated against a support structure when in the first position and spaced from the support structure when in the second position.

Abstract: A heat shield vane support may have a structure including at least one of a cylindrical and a frustoconical portion with an outboard diameter and an inboard diameter extending about an axis and extending axially between a forward face and an aft face and may comprise a flange extending circumferentially about the aft face radially inward from the inboard diameter, a plurality of anti-rotation features distributed circumferentially about the inboard diameter extending radially inward from the inboard diameter and extending axially with respect to the cylindrical structure between a forward edge and an aft edge defining a length L, and a plurality of teeth distributed circumferentially about the forward face and extending axially from the forward face.

Abstract: An active clearance control system for a gas turbine engine includes a ring seal engageable with a multiple of air seal segments.

Abstract: A blade tip clearance system includes first and second control rings. The first control ring has a first coefficient of thermal expansion (CTE) and a first thermal response rate. The second control ring is located radially outward of and operatively connected to the first control ring and has a second CTE that is different from the first CTE and a second thermal response rate that is different from the first thermal response rate. Thermal expansion and contraction of the first and the second control rings controls a radial position of the blade tip clearance system relative to a rotating blade component.
