Abstract: The connector system (30) includes a pivoting member (38) pivotally attached to a guide anchor (36) that is moveable secured within a guide track (34). The guide anchor (36) is movably secured between first and second strength walls (58, 62). At least one guide shoulder (70) and the pivoting member (38) define throughbores (74, 76, 78) that receive a rod (92) of a rod-and-bracket connector (88) to pivotally secure the pivoting member (38), such as a convergent flap (26) of an exhaust nozzle assembly (22). The rod-and-bracket connector (88) utilizes an L-shaped arm (96) to eliminate need for a large thread and lock nut assembly (86) between the strength walls (58, 62) to thereby facilitate use of larger, stronger guide shoulders (70, 72) between the strength walls (58, 62) to maximize strength of the connector system (30) while minimizing its volumetric displacement.

Abstract: An air modulating system for a gas turbine engine includes a fixed plate with a fluid passage inlet, a floating plate with a first side adjacent to the fluid passage inlet, an actuated mount configured to move the floating plate relative to the fixed plate, and a linkage element for connecting the floating plate to the actuated mount. The linkage element includes a mounting flange configured to slidably engage the floating plate.

Abstract: A blocker door assembly which may be for a cooling system that may be applied to a gas turbine engine includes a plurality of blocker doors circumferentially spaced about an engine axis. Each blocker door is constructed and arranged to move in a circumferential direction to, at least in-part, control air flow through a passage in an adjacent fixture. A sync-ring is concentrically located about the engine axis, disposed in an annular first duct in direct communication with each passage, and engaged to each one of the plurality of blocker doors for simultaneous operation. The sync-ring is aero-dynamically shaped to reduce surrounding airflow resistance.

Abstract: A multi-component fastener is provided having a body and a sleeve. The body has a shank that extends lengthwise between a head and a distal end. The shank includes a first outer surface. The body includes a first material. The sleeve has a wall defined by an outer surface and an inner surface. The inner surface defines an interior cavity. The wall extends lengthwise between a first end and a second end. At least a portion of the sleeve outer surface contiguous with the first end is threaded. The sleeve includes a second material that is dissimilar to the first material. A portion of the shank including the distal end is disposed within the interior cavity of the sleeve. The sleeve and the shank are fixed to one another.
