介绍了一种新的压气机气动性能试验方案。该数据集是为1995年投入运行的德累斯顿四级低速研究压缩机（LSRC）提供的。压缩机由四个相同的级组成，其前面是进口导叶。该数据集将用于带悬臂定子叶片的压缩机的参考叶片。该叶栅是根据喷气发动机高压压气机中间级叶型设计的。本文提供了叶片几何形状以及各种流场测量结果。这包括压气机图、选定的压力分布和采用传统技术（例如皮托管探头、5孔探头）进行流场测量的其他结果。此外，近年来在该压气机中讨论了叶排相互作用的不同方面。采用激光多普勒测速技术对某转子叶排内的周期性非定常流场进行了研究。将提供关于非定常叶型压力和叶型边界层的进一步结果。补充，数值计算结果将与实验进行比较。结果可用于压缩机的几个阶段和不同的操作点。通过该测试用例，将提供一个多级轴流压缩机空气动力学的独特数据库，可用于验证数值代码。版权所有© 2008 by ASME
This paper introduces a new test case for compressor aerodynamics. The dataset is provided for the Dresden four-stage Low-Speed Research Compressor (LSRC), which was put into operation in 1995. The compressor consists of four identical stages, which are preceded by an inlet guide vane. The data set will be provided for the reference blading of the compressor with cantilevered stator vanes. This blading was developed on the basis of the profiles of a middle stage of a high-pressure compressor of a jet engine. This paper makes available the blading geometry as well as a variety of flow field measurement results. This includes the compressor map, selected pressure distributions and other results of flow field measurements with conventional techniques (e.g. Pitot probes, 5-hole probes). Furthermore different aspects of blade row interactions were addressed in this compressor within recent years. The periodical unsteady flow field within a selected rotor blade row was investigated using Laser-Doppler-Anemometry. Further results on the unsteady profile pressures and profile boundary layers will be provided. Supplementary, numerical results will be compared to the experiments. Results are available for several stages of the compressor and different operating points. With this test case a unique database for the aerodynamics in a multistage axial compressor will be provided that can be used for the validation of numerical codes.Copyright © 2008 by ASME
