摘　　要：介绍了基于STC长叶片设计平台完成的600MW等级二排汽空冷汽轮机长叶片的设计开发,主要从气动和强度振动两方面阐述了末级叶片的设计要点和工作特性。结果表明,该末级叶片具有良好的振动特性和变工况特性,并对新的长叶片的设计开发有一定的指导意义。The development is presented on last stage blade of 600MW class air cooling steam turbine with two-casing, which was carried out based on the platform of STC＇ s long blade design. The design points and operational characteristics are mainly described in term of aerodynamics, intensity and vibration. It is demonstrated that the long blade is of a lower vibration and better off-design performance, and it has a significant effect to the development of the last stage blade.
