摘要： The present invention is related to a wear liner assembly (42A) for placement between a mounting foot (40) of a platform (36) and a case (30) of a gas turbine engine including first and second annular liner segments (44A,46A). First and second segments (44A,46A) are mounted on a portion of a radially outward and a radially inward surface (58,60) of the mounting foot (40) respectively . The first segment (44A) includes a first flat portion (70) and a first curved portion (72) extending from a first end (68) of the first segment (44A). The second segment (46A) includes a second flat portion (76) and a second curved portion (78) extending from a first end (74) of the second segment (46A). A split (82) is provided between first and second segments (44A,46A). Thus, the segments (44A,46A) may move independently allowing a tighter fit and reducing mounting complexity.

摘要： An airfoil (60;160) includes an airfoil section (66) that defines an airfoil profile (AP). The airfoil section (66) includes first and second airfoil pieces (72,74;172,174). The first airfoil piece (72;172) defines a portion of the airfoil profile (AP) and has a first slot (80a;180a). The second airfoil piece (74;174) defines a different portion of the airfoil profile (AP) and has a second slot (80b; 180b). The first slot (80a;180a) and the second slot (80b;180b) together form a seal slot (84;184a), and a seal (86;186a) is disposed in the seal slot (84;184a).

摘要： An axial fan assembly (10) for a vehicle cooling system includes an axial flow fan (20) between an inlet stator (18) and an outlet stator (18). The inlet stator (18) has inlet stator vanes which extend outwardly from a first inner support ring. Each inlet stator vane has a downstream edge which has a tangent which is oriented at a first variable angle with respect to a first end plane which is perpendicular to a fan axis. The first variable angle increases with increasing distance from the first inner support ring. The outlet stator (22) has outlet stator vanes which extend outwardly from a second inner support ring. Each outlet stator vane has an upstream edge which has a tangent which is oriented at a second variable angle with respect to a second end plane which is perpendicular to the fan axis. The second variable angle decreases with increasing distance from the second inner support ring.

摘要： A centrifugal ceiling fan adapted to evenly ventilate and heat its surrounding area. The fan comprises a casing defining a top, a side, and a bottom. The air inlet is provided in the top and the air outlet comprises a first passage provided in the side and a second passage provided in the bottom, and a central dome for regulating the flow of air between the first passage and the second passage to a desired proportion. The fan comprises a centrifugal propeller having blades which are curved and have a variable width such that rotation of the centrifugal propeller causes air to be received from said air inlet and to be pushed from said air outlet in substantially all directions between the first direction and the second direction. The dome comprises a heat source for heating air pushed downward from the bottom. Whereby, unheated air is pushed sideways and heated air is pushed downward and for evenly ventilating and heating a room in which the centrifugal ceiling fan is installed.

摘要： A gas turbine engine is provided that includes a compressor section, a combustor section with a multiple of pre-swirlers, a diffuser case module, and a manifold. The diffuser case module includes a multiple of struts within an annular flow path from said compressor section to said combustor section, wherein at least one of said multiple of struts defines a mid-span pre-diffuser inlet in communication with said annular flow path. The manifold is in communication with said mid-span pre-diffuser inlet and said multiple of pre-swirlers.

摘要： A blower fan (40) includes a plurality of blades (42) radially extending from a boss (41) provided at the rotary center and spaced apart from each other in the rotational direction, and a ring portion (43) connecting outer peripheral ends of the blades (42) in a ring shape. An inner peripheral wall surface of an end part (34) on an air-flow downstream side of a cylindrical portion (31) is disposed on the outside in a radial direction of the rotary shaft in the blower fan (40), with respect to an end part on the air-flow downstream side of the ring portion (43). The end part (34) on the air-flow downstream side of the cylindrical portion (31) is positioned outward in the radial direction of the rotary shaft, as toward the air-flow downstream side. Thus, the blower can prevent the backflow air from being swirled, thereby reducing noise.
