Abstract : The report presents the aerodynamic calculations and describes the mechanical features of a test rig that has been designed at the Turbopropulsion Laboratory, Department of Aeronautics, for research work on a special type of centrifugal compressor. This so-called Hybrid compressor consists of a centrifugal rotor with 180 deg flow deflection in the meridional plane followed by an axial flow diffusor. The report establishes a method to predict the off-design performance of the compressor, which can be applied also to conventional centrifugal compressors. Extensive use is made of modern programmable calculators, and programs are presented to show the effectiveness of these tools in engineering endeavors. (Author)
