摘要： PROBLEM TO BE SOLVED: To provide a turbine scroll device for controlling increase of loss caused by a flow-in angle mismatch due to low energy fluid of a boundary layer to grow on a scroll wall surface and to flow in a turbine. SOLUTION: A means for preventing the low energy fluid of the boundary layer to grow on the scroll wall surface from directly flowing in a nozzle or a moving blade inlet side is provided on a boundary layer flow surface continuing to a turbine inlet side of at least shroud wall surface in a scroll inner diameter side to control increase of loss caused by an operation gas flow-in angle mismatch. The prevention means are a vertical wall of a fin or others, a wall surface shape having larger diameter as it gets closer to a turbine inlet side, a shroud wall surface of the turbine moving blade or a passage bypassing to a turbine outlet part.

摘要： PURPOSE:To respectively and effectively cool a turbine disc and a turbine moving blade by forming a cooling passage near the turbine moving blade from a cooling air chamber as well as communicating the cooling air chamber arranged near the turbine disc with a scavenging chamber of a main engine by means of a cooling pipe. CONSTITUTION:A turbine moving blade 2 is implanted in the outer periphery of a turbine disc 3, and also the turbine disc 3 is connected to a compressor impeller by a rotor shaft 4. In this case, a cooling air chamber 5 is composed of the turbine disc 3, a chamber wall 8, gas labyrinth 7 and a gas inlet casing 6. Moreover a cooling pipe 9 is arranged by penetrating the chamber wall 8 by means of its one end and by communicating the other end with a scavinging chamber of a main engine. And a cooling passage 10 for exhausting cooled air after the cooled air is made to pass in the gap between the gas labyrinth 7 and the turbine disc 3 from the cooling air chamber 5 is formed. Thereby cooling efficiency can be secured without arranging any cooling air passage in the turbine blade 2.

摘要： PURPOSE:To provide the mounting structure of an exhaust gas turbine supercharger punching plate which improves the fatigue strength of a punching plate weld part more than a conventional embodiment when stress is repeatedly exerted through vibration of a frame on a main engine under a state that the gas inlet casing of an exhaust gas turbine supercharger is thermally expanded. CONSTITUTION:The mounting structure of the punching plate of an exhaust gas turbine is formed so that the bottom of the mounting part of the lower thick plate C of the punching plate is formed in a taper shape. In mounting of the punching plate to an installation bed, deformation is effected so that displacement delta2 in a reverse direction to displacement delta1 owing to thermal expansion of a gas outlet casing 7 during operation is effected to perform initial mounting.
