Abstract: PROBLEM TO BE SOLVED: To provide a stator assembly provided with stator vane trains to be repeatedly positioned after replacement and having an allowable level of durability and a replacing property. SOLUTION: A stator vane blank for forming a stator vane for a rotary machine includes a forged head part 84 having a pair of surfaces provided with an angle forming an outward surface 104, and these surfaces has an angle larger than the angle of a pair of surfaces facing to an air foil and provided with an angle forming an inward surface 106. The outward surface 104 is provided with about nine degree of angle α, and the inward surface 106 is provided with about three degree or less of angle β.

Abstract: PROBLEM TO BE SOLVED: To provide an axial flow gas turbine engine which can minimize a gas dynamical clearance under cruising condition of the engine, which can be assembled, and in which a low pressure compressor and a low pressure turbine assembly can be inspected. SOLUTION: A rotary machine which has rotor raw material 54-56, 114 and seal lands 86, 112 has been disclosed. Details of various structures are developed for easy assembly of machine. In one embodiment, clearance is established between a moving blade 66 and a seal land 86 to make assembly of components possible, and a certain clearance which is acceptable under steady state of an engine is supplied.

Abstract: PROBLEM TO BE SOLVED: To provide an adhering device to have durability and handling difficulty being low enough to be allowable. SOLUTION: A stator assembly contains a peripheral extending preformed lab strip 58. The lab strip is adhered to an inside shroud 56 by applying a bond (a registered trade mark) material 86, such as an adhesive and a primer, directly on a gap between the inside shroud 56 and the pre-formed lab strip 58. The inside shroud 56 is formed of a thermoplastic material and the lab strip 58 is formed of a preformed silicone rubber, and a primer of epoxy resin is provided such that relative operation with the thermoplastic material is effected. The pre-formed lab strip 58 is deformed radially inwardly during manufacture of an assembly and this constitution extends a bond material 86 in a vertical direction, i.e., the direction of the width of a blade, and a shearing strength on a contact surface is increased.

Abstract: PROBLEM TO BE SOLVED: To provide a stator assembly having a row of stator vanes repeatedly positionable after replacement, having an allowable level of durability and replaceability. SOLUTION: This stator assembly comprises a plurality of vanes extending into an operating medium gas flow passage through a case extending in circumferential direction. In this case, the stator assembly comprises a surface 76 facing inward on a base part 48, and the inward facing surface 76 is connected, in the state of being installed, to a flat surface 74 corresponding to a non-flow passage surface of a casing at a position of each vane. In one embodiment, these surfaces are on the same plane.

Abstract: PROBLEM TO BE SOLVED: To provide a stator assembly having a row of stator vanes with an allowable level of durability and replaceability. SOLUTION: This stator assembly comprises shrouds. The detail of various coinfigurations limiting the movement of stator vanes 28 into a flow path by the limitation of the shrouds is expanded. For example, a clip member 62 extends throiugh an opening part 64 located at a vane tip part 52 of the stator vane 28, and the clip member 62 is disposed on a non-flow path surface of an inside shround 56 so as to limit the vane tip part 52 of the stator vane 28 for an inward movement.

Abstract: PROBLEM TO BE SOLVED: To minimize gas dynamic clearance in the cruise operating state of an engine by supplying a lubricant to the surface of a seal land. SOLUTION: A rotary machine assembling method has a step of forming a sub-assembly including a lower pressure compressor rotary assembly and a step of forming a case assembly for a low pressure rotary assembly. Further, the method has a step of supplying a lubricant to at least one seal land 112 before the case assembly is assembled in the rotary assembly. The clearance can be made in the minimum clearance dimensions by using silicone oil as a lubricant, and a pilot rod of a blade which is normally difficult to be turned by hand can be freely turned by supplying silicone foil to the seal land. Lowering of characteristic of a component where the lubricant touches is prevented.

Abstract: A gas turbine engine comprises a rotor (50) provided with rotor blades (50,56,58,62,64,66), and a stator (68) provided with stator varies (92,94,96,98,102,104). Airseals are formed between the rotor (56) and stator (68) by providing rubstrips (86) adjacent the tips of the rotor blades (54-66), and by providing seals knife edge seals (112,114) adjacent the tips of the stator varies (92-104). In order to minimise the clearance between the rotor and stator during operation, and hence improve the efficiency of the engine, during construction an interference fit is provided between the rotor (50) and stator (68) say between the rotor blades (54-66) and the rubstrips (86), so that during operation the clearance between the rotor (50) and the stator (68) is minimised and the engines efficiency is improved.
