    Abstract: A fairing assembly (30) is provided which is located between a frame hub (32) and an engine casing (31). The assembly provides for use of a metallic structure in combination with a light weight low alpha material in order to improve engine efficiency and performance. Relative growth between the dissimilar materials is compensated for by a flexible bracket (90) which provides biasing force on one of the assembly components in a cold engine condition as well as allowing for growth at the high temperature operating conditions of the engine.

    Abstract: PROBLEM TO BE SOLVED: To enable inner/outer races to always hold an engaging state with rolling bodies with simple constitution by concentrically fixing a low density high circumferential strength support ring to the inner race fixed to a second annular member and a first annular member arranged on the outside. SOLUTION: A roller bearing 30 having plural rolling bodies 32 is arranged in an operable state between an outer race 34 and an inner race 36 between a high pressure turbine rotor 10 and a low pressure turbine rotor 23. The outer race 34 is fixed to the annular extension part 39 in the rear of a high pressure turbine disk 21 on the inside surface 40 of the rotor 10. The inner race 36 is fixed to the outside surface 42 of a low pressure shaft 28. A high pressure shaft rotates at a higher speed than the low pressure shaft 28, and due to a centrifugal load, the outer race 34 can cause looseness of a bearing 30 by trying to swell in the radial direction. Then, a lightweight or low density annular support ring 50 is arranged outside in the radial direction of the outer race 34. The support ring 50 is manufactured by a TMC material so as to endure hoop stress without swelling since it has titanium fiber 51 extending in the circumferential direction.

    Abstract: PROBLEM TO BE SOLVED: To provide a lean premix pressure combustor which prolongs the life time of the combustor and reduces complexity of maintenance and costs therefor. SOLUTION: A combustor dome module comprises a mixer tube, having a hollow heat shield sealingly joined around the outlet end thereof. The module can then be assembled in an array form for defining a combustor dome, with each module being individually removable therefrom.

    Abstract: PROBLEM TO BE SOLVED: To provide a moving blade holding device and holding method, for preventing the moving blades of a rotary machine from being axially displaced forward or backward. SOLUTION: A circumferential hub slot 16 is formed along the periphery of a machine hub 10. Moving blade holding slots 18 are provided matcheable to the circumferential hub slot when the moving blades are machined-processed and the moving blades are accommodated in an opening 12 having the shape corresponding to the hub. One or more ring segments 22 are fixed to the moving blade holding slot and the circumferential hub slot to prevent the moving blades from being axially displaced. The ring segments are fixed to a matching slot using a key-assembly 30 through a screw part 38 pushed in radially outside by a hook part 34 for accommodating the ring segments, and a nut part 50. A cap 52 can be provided as a redundant auxiliary load path for centrifugal load to be applied to the key. As another process, the key-assemble can be provided in a dovetail of the moving blade.

    Abstract: PROBLEM TO BE SOLVED: To provide a support structure system permitting proper management of a substantial disorder in fan balancing without applying particular weight to a gas turbine engine. SOLUTION: A support structure 210 for a gas turbine engine 200 includes a support arm 212 installed extending in between a low pressure shaft 202 and a plurality of rotor blades 236. The support arm 212 includes a fuse 220 with a low melting point. After melting of the fuse a high pressure stub shaft supports the low pressure shaft both axially and radially. An axial clearance between part of the low pressure shaft and the stub shaft permits motion of the low pressure shaft after melting of the fuse. A radial clearance between the stub shaft and the low pressure shaft permits a radial deflection of a low pressure rotor unit after melting of the fuse.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and device for directing air flow to a compressor bore. SOLUTION: A gas turbine rotor assembly contains a plurality of aerodynamic devices to direct a flow of air to the inside in a radial direction. The gas turbine engine rotor assembly contains a rotor shaft having a plurality of openings. An aerodynamic device contains a pair of blade segments and a pair of side walls. An outside surface having a contour shape contains an opening and the aerodynamic device can be installed in a manner to make contact with the inside surface of the rotor shaft and a flange ring demarcates a pocket. The aerodynamic device is fitted in the inside of the pocket with the openings adjusted to concentricity.
