    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, 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.

    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 translation: 燃气涡轮发动机转子部分包括具有从转子体上的位置轴向延伸的凸缘的转子体。 凸缘限定了凸缘径向向内的径向内表面，并且毂从转子轴向延伸并且超出凸缘。 毂具有与凸缘径向内表面间隔开的径向外表面。 在凸缘的径向内表面和毂的径向外表面之间限定第一距离。 刀刃密封件在径向外端具有至少一个尖刀密封部分。 径向向内延伸的臂部分从密封件延伸，并且轴向向内延伸的部分从径向向内延伸的部分轴向向内延伸。 轴向向内延伸的部分具有径向外表面和径向内表面，间隔开第二距离。 第二距离小于第一距离。 轴向向内延伸的部分被容纳在转子的径向内表面和轮毂的径向外表面之间，使得刀刃密封件在凸缘和轮毂之间自由浮动。
