Field Measurements Of Blade Stresses On Industrial Turbomachines
High blade stresses can be induced in axial compressors by various asymmetrical flow conditions or adverse working conditions. A series of measurements were carried out on industrial and gas turbine axial compressors. After a brief review of the various measuring methods, test results are presented and commented. The information gained refers to various working conditions, such as rotating stall, surging, partial injection of the turbine of superchargers for Diesel engines as well as to the influence of the wake of blading, especially for compressors with movable guide vanes. The influence of lacing wires on axial compressor bladings is presented and commented with respect to efficiency loss and increase of noise level.
