Abstract: A compressor rotor has a rotor centered on an axis, and a groove with opposed side edges. The groove receives a plurality of removable compressor blades, and has tangential sides. The tangential side surfaces are in contact with said tangential sides of the groove, and at least one slot is cut into the side edges. A first radial distance is measured from a radially outer edge of the side edge to a radially outer beginning point of the tangential sides of the groove. A second radial distance is radially between the radially outer beginning point of the tangential sides to a radially inner end of the tangential sides of the groove. A ratio of the first and second radial distance is between 1.1 and 5.0.

Abstract: A segment for a knife edge seal includes an arcuate segment with a first end with a first end surface and a second end with a second end surface. The first end surface and the second end surface are complementary and overlapping when the first end surface and the second end surface interface with ends of adjacent segments.

Abstract: A seal for a gas turbine engine and a gas turbine engine employing such a seal are disclosed. More specifically, the engine includes a knife edge seal which is better able to withstand the extremely high temperatures and mechanical loads to which gas turbine engine components are increasingly subjected. By moving the knife edge seal to the aft hub and cantilevering its angle off of vertical, thermal and mechanical loads are balanced and thus thermal mechanical fatigue life is improved while low cycle fatigue is maintained.

Abstract: A spacer (26) of a gas turbine engine (10) is reinforced with a fiber (34). The fiber (34) can be cured with a substrate (38) to form a fiber reinforced composite material (42). As a gas turbine engine (10) operates, the rotation creates forces which can deform, expand, contract or translate certain gas turbine engine components, including spacers (26). These forces can adversely affect gas turbine engine performance and reliability, particularly when they are either unpredictable or difficult to control. Reinforcing a spacer (26) with a fiber (34) may allow a lower system weight, more compact or configurable internal packaging or a high degree of reinforcement.

Abstract translation: 燃气涡轮发动机（10）的间隔件（26）用纤维（34）加强。 纤维（34）可以用基底（38）固化以形成纤维增强复合材料（42）。 当燃气涡轮发动机（10）操作时，旋转产生能够使包括间隔件（26）在内的某些燃气涡轮发动机部件变形，膨胀，收缩或平移的力。 这些力可能不利地影响燃气轮机的发动机性能和可靠性，特别是当它们不可预测或难以控制时。 用纤维（34）加强间隔件（26）可以允许较低的系统重量，更紧凑或可配置的内部包装或高度的增强。

Abstract: A gas turbine engine rotor section includes a rotor body with a ledge extending axially from a location on the rotor body. The ledge defines a radially inner surface radially inwardly of the ledge, and a hub extends axially from the rotor, and beyond the ledge. The hub has a radially outer surface spaced from the ledge radially inner surface. A first distance is defined between the radially inner surface of the ledge and the radially outer surface of the hub. A knife edge seal has at least one pointed knife seal portion at a radially outer end. A radially inwardly extending arm portion extends from the seal, and an axially inwardly extending portion extends axially inwardly from the radially inwardly extending portion. The axially inwardly extending portion has a radially outer face and a radially inner face, which are spaced by a second distance. The second distance is less than the first distance. The axially inwardly extending portion is received between the radially inner face of the rotor and the radially outer face of the hub, such that the knife edge seal is free floating between the ledge and the hub.

Abstract: A rotor body rotates about an axis of rotation. A ledge provides a holding structure for holding blades. A plurality of blades are positioned beneath the ledge. A load slot is sized to allow a mount portion of the blades to be moved radially inwardly of the ledge. The blades are moved circumferentially to have the mounted structure radially inwardly of the ledge. A lock slot is positioned on one circumferential side of the load slot. The lock slot is formed to receive a lock, and the lock is partially received within a portion of at least one of the blades, to lock the blades within the rotor, and a shield slot on a second circumferential side of the load slot. The shield slot is sized to be different from the lock slot such that a lock cannot be inadvertently positioned within the shield slot.
