前言“东风Ⅰ型”压气机母型级经过了20年的坎坷路程最近由上海成套设计所组织进行了技术鉴定,获得了很高的评价。尽管它设计于60年代中期,但是按照它设计出的压气机的气动性能指标还是能够和80年代国外同类型的产品相媲美。尤为可贵的是这个母型级不仅积累了叶栅资料、单级试验、多级试验、整机试验等宝贵的试验资料,同时还总结出了一套运用这个级设计压气机的计算方法,它给推广应用这个母型级提供了可靠的 Preface “Dongfeng Type Ⅰ” compressor mother-level after 20 years of rough range recently organized by the Shanghai Institute of complete technical appraisal, received a high rating. Although it was designed in the mid-1960s, the aerodynamic performance of compressors designed according to it was comparable to those of the same type in the 1980s. Particularly valuable is that this mother class not only accumulated valuable information such as cascade data, single-stage test, multi-stage test, machine test and other valuable test data, but also summed up a set of calculation compressor using this stage design method, it To promote the use of this mother-class provides a reliable
