摘要: A vane structure for a gas turbine engine. The vane structure includes a radially outer platform and a radially inner platform, and an airfoil having an outer wall extending radially between the outer platform and the inner platform. A cooling passage is defined within the outer wall and has a plurality of radially extending channels. An outer end turn structure is located at the outer platform to conduct cooling fluid in a chordal direction between at least two of the channels. The outer end turn structure includes an enlarged portion wherein the enlarged portion is defined by an enlarged dimension, in a direction transverse to the chordal direction, between the at least two channels.

摘要: Bi-casting a platform (50) onto an end portion (42) of a turbine airfoil (31) after forming a coating of a fugitive material (56) on the end portion. After bi-casting the platform, the coating is dissolved and removed to relieve differential thermal shrinkage stress between the airfoil and platform. The thickness of the coating is varied around the end portion in proportion to varying amounts of local differential process shrinkage. The coating may be sprayed (76A, 76B) onto the end portion in opposite directions parallel to a chord line (41) of the airfoil or parallel to a mid-platform length (80) of the platform to form respective layers tapering in thickness from the leading (32) and trailing (34) edges along the suction side (36) of the airfoil.

摘要: A method of comparing parts by comparing metadata representing the part topologies to identify identical or near identical parts. Metadata representing the geometry of a plurality of parts is compiled into a database. Corresponding metadata of a subject part may be determined and compared to the metadata stored in the database. The metadata may include values representing the volume, surface area, and principal moments of inertia of the parts. The metadata may additionally contain values representing the location of the cross-sectional center of gravity with respect to the point of intersection of the principal moments, for each of the planes of the principal moments, thereby allowing mirrored parts to be differentiated. The comparison of complex parts may be performed by comparing as few as five metadata values using simple database management tools.
