空冷机组末级叶片的初步研究与分析

Research and Analysis to the Last Stage Blade of Air Cooling Steam Turbine

末级叶片的研究是研制开发空冷机组的关键。从热力、气动、强度振动等几个方面对末级叶片的工作特性、设计要点等方面进行论述,对于末级叶片的设计开发有一定的指导意义。

Research and analysis to the last stage blade is the key to manufacture air-cooling steam turbine. This paper discusses operational factors and design point aspects of the last stage blade from thermodynamics, aerodynamics, intensity and vibration etc. which will have instruction meaning for the design and manufacture to the last stage blade。
