Steady performance of the rig is found to be satisfactory at the design condition. Experimental particulars for the acoustic test are given and some of the test results are shown for both operation modes of a single rotor and/or the rotor plus stator cascades. One of the primary objectives in the present experiment is the effect of the blade tilting on the interaction between the blade cascades in relative motion, therefore an analytical model including this effect has been also proposed., 資料番号: SA0125620000}, pages = {563--583}, title = {<論文>軸流圧縮機からの回転騒音}, volume = {14}, year = {1978} }
