短周期涡轮实验的发展趋势

对国外短周期涡轮实验技术的发展及其应用范围开拓的情况进行了综述和分析.比较了长短周期涡轮实验技术各自的优点和不足.近年来,在发展高性能航空发动机的需求带动下, 短周期涡轮实验技术正在努力克服自身的薄弱环节,力争达到长周期涡轮实验技术所能达到的性能测试精度.其发展目标是争取部分替代长周期涡轮实验,由单纯机理性实验平台向部件性能研发平台扩展.同时,作为重要的基础研究平台,短周期涡轮实验台在机理研究领域也有所拓宽,开始被应用于新设计理念的验证、CFD设计分析软件的校验等新的领域.

Development trend of short-duration turbine experiments

The development and expansion of overseas short-duration turbine testing techniques were summarized and analyzed by comparing the advantages and disadvantages of short-/long-duration turbine testing techniques. Spurred by the demand of developing high performance aeroengine, the short-duration turbine testing technique was improved greatly to achieve the measurement accuracy of long-duration turbine testing technique.The purpose of short-duration turbine testing technique is to replace partially long-duration turbine testing technique by developing from a mechanics investigation platform into a performance investigation platform. As an important basic study platform, short-duration turbine testing platform has developed in the mechanism research field and has now been applied to validation of new design concept and check of CFD software.
