TURBINE ROTOR

PROBLEM TO BE SOLVED: To provide a turbine rotor for a high temperature operation giving no bed effect to the turbine strength. SOLUTION: This turbine rotor 20 is provided with plural dovetail slots 24 among which disk stanchions 26 are formed respectively. The disk stanchions 26 are provided with p...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a turbine rotor for a high temperature operation giving no bed effect to the turbine strength. SOLUTION: This turbine rotor 20 is provided with plural dovetail slots 24 among which disk stanchions 26 are formed respectively. The disk stanchions 26 are provided with plural tongues in the adjacent slots at intervals in the radial direction on top lands 26a and on the lower side. Plural turbine blades 28 each having a dovetail 28a are fitted in the dovetail slots 24 to be kept in the radial direction. A platform 28b is integrally connected to the dovetails 28a, and it is arranged extensively in the peripheral direction to form the radial direction inside passages adjacently to the next platform. An air foil 28c is integrally extended from the platform 28b to extract energy from the combustion gas flowing on it. A heat insulation film 36 is fitted to insulated heat between the platform 28b and the stanchions 26 and lower the temperature of the disk stanchions 26.
