Abstract: A control system for a gas turbine engine is disclosed. In embodiments, control system includes a controller and a high speed recorder. The controller obtains a sensor value from a sensor connected to the gas turbine engine and publishes a tag that includes the type of event, the sensor value, and a timestamp. The high speed recorder checks the tag for an overspeed event. If an overspeed event is detected, the high speed recorder records values provided by the tag.

Abstract: A flanged component for a gas turbine engine is disclosed herein. The flanged component includes a flange body with a flange mating surface and a plurality of threaded features. Each threaded feature includes a threaded portion and a relief portion. The threaded portion has threads and extends into the flange body from the flange mating surface. The relief portion extends into the flange body from the flange mating surface located outward from the threaded portion forming a rim portion therebetween. The rim portion includes an upper rim surface having an annular shape. The relief portion includes an inner surface extending from the rim and tapering outward from the upper rim surface.

Abstract: An air blocker ring assembly including a proximal end and a distal end, a blocker ring, and a blocker ring support cooperating with the blocker ring to form a circumferentially extending split line at an interface between the blocker ring and the blocker ring support. The proximal end of the proximal ring assembly has a circumferential leading edge, and the circumferentially extending split line is located at least one of radially inside or radially outside the leading edge.

Abstract: An air blocker ring assembly includes a proximal end, a distal end, a blocker ring, and a blocker ring support. The blocker ring has a first protrusion, a second protrusion, and a third protrusion. The blocker ring support has a recess. The first protrusion of the blacker ring is received in the recess. The blocker ring is circumferentially discontinuous about a circumferential slot. At least a portion of the first protrusion is located circumferentially opposite the slot, and the second and third protrusions terminate at the slot.

Abstract: A fluid line clamp includes one or more blocks with holes for receiving fluid lines therein. The fluid line clamp further includes a first backing plate, a second backing plate, and a shielding plate. The first and second backing plates are spaced apart from each other to receive the blocks therebetween. The shielding plate is disposed at a distance from the blocks and includes an inner surface, and an outer surface. The inner surface of the shielding plate is rigidly attached to the backing plates. The outer surface of the shielding plate is configured to rigidly attach to a hot body of a machine.
