摘要： A fan containment system comprising an annular casing element and a hook projecting in a generally radially inward direction from the annular casing element. A fan track liner is connected to the hook via a fastener. The fan track liner has a forward end proximal to the hook and a rearward end distal to the hook. A pivot member protrudes radially inward from the annular casing element and is arranged and positioned between the forward and rearward end of the fan track liner such that a forward portion of the fan track liner is pivotable about the pivot member, so that upon release of a fan blade the forward portion of the fan track liner pivots about the pivot member into a voidal region provided between the annular casing element and the forward portion of the fan track liner to encourage engagement of the hook with a released fan blade.

摘要： The method involves providing rotor having number of rotor blade ring forming blades, for determining diameter of rotor with rotor blades. The rotor with rotor blade ring is set in rotational movement. A distance measurement device (124) is assigned to the region of rotor blade ring in order to measure the distance to rotor blades, which are rotating past the distance measurement device, so that rotor diameter is determined in conjunction with distance between sensor and axis of rotor. An independent claim is included for measuring system for rotor of turbomachine.

摘要： An arrangement for detecting axial movement of a shaft (9), which arrangement comprises a first part (1) and a second part (2), the second part (2) comprising a surface (2a) being made of an electrically conductive material. The shaft is attachable to the first part (1) or to the second part (2)and the surface (2a) can be brought into sliding contact with the first part (1)and apart from it. The arrangement further comprises a sensor (3) being made at least partly of an electrically conductive material and arranged in the first part (1). The sensor (3) comprises a first area (3d) that is electrically connected to the surface (2a) of the second part (2)and a second area (3e) that is in electrical contact with the surface (2a) of the second part (2) when the first part (1) and the second (2) part are in sliding contact with each other so that a closed electrical circuit is formed. When the first part (1) and the second part (2) are at a distance from each other, the second area (3e) is at a distance from the surface (2a)of the second part (2) so that an open electrical circuit is formed. The arrangement also comprises means (5) for detecting opening and closing of the electrical circuit.
