Surface roughness of real operationally used compressor blade and blisk

The data set contains three dimensional measured surfaces of real worn compressor blades from real mid-sized air craft engine high pressure coompressors. Three stages of the compressor are measured. The first stage, the centre stage and the last stage. Also surface data of a real worn Blisk from a small aircraft engine will be published. We are currently preparing the data. Further information of the data are given in: Gilge, P.; Kellersmann, A.; Friedrichs, J.; Seume J.R. (2019): Surface roughness of real operationally used compressor blade and blisk.
