摘要： When a combination of a vane type of a stator vane and a vane type of a stator vane for one straightening plate is the same as a combination of a vane type of a stator vane and a vane type of a stator vane for the other straightening plate, positions of the first straightening plate side connection portions and the second straightening plate side connection portions of the one straightening plate and the other straightening plate are the same as each other. When the combinations are different from each other, at least one of the positions of the first straightening plate side connection portions of the one straightening plate and the other straightening plate and the positions of the second straightening plate side connection portions of the one straightening plate and the other straightening plate are different from each other.

摘要： A fluid-washed assembly for an axial flow machine, such as a fan blade assembly for a gas turbine engine. The assembly has an array of members (124) circumferentially spaced about the machine axis, each member extending from a radially inner end to a radially outer end with respect to the axis of rotation of the machine. Each member has opposing outer surfaces extending between a leading edge and a trailing edge thereof with respect to the direction of oncoming fluid flow in use. A plurality of annulus fillers are provided between each member (124), wherein each annulus filler (130,132) is affixed against an outer surface of an associated member at a location between the inner and outer ends in a manner which supports the annulus filler in use. The annulus filler (130,132) may be suspended by the member. In preferred embodiments, the annulus fillers comprise a composite material which is bonded to the associated member using an adhesive.

摘要： There is disclosed an annulus filler (21) for mounting to a rotor disc (22) of a gas turbine engine and for bridging the gap between two adjacent blades (25) attached to the rotor disc. The annulus filler comprises a first part (20) which is connectable to the rotor disc between the positions of said adjacent blades, preferably before the blades are connected to the rotor disc. The annulus filler also comprises a separate second part (38) which is configured for engagement with the first part after the adjacent rotor blades have been connected to the rotor disc. The filler is characterised in that said first part has, in transverse cross-section, a pair of spaced-apart and generally radially oriented arms (26) resiliently biased towards an installation configuration in which it is spaced from each said blade by a respective clearance gap (G), and an operational configuration in which it contacts each of said blades. Engagement of the second part with the first part is effective to urge the first part from said installation configuration to said operational configuration and thus into contact with said blades. The first part may have at least one mounting region for connection to the rotor disc and be configured to allow, in said first step of said procedure, the or each mounting region to remain visible from a radially outer viewpoint. A method of mounting an annular filler to a rotor disc of a gas turbine engine is also disclosed.

摘要： An annulus filler for installation between blades, such as fan blades, of the rotor of a gas turbine engine comprises a channel 13 which accommodates a post 6 defined between blade slots 4 of the disc 2. A chocking surface 24 of the annulus filler 12 contacts regions of a contact surface 26 of the post 6 to chock the head 10 of the post 6 within the channel 30. The annulus filler 12 is thus supported along the axial length of the post 6, enabling it to withstand circumferential forces generated on rotation of the disc 2.
