Analyses of non-uniform cascade flutter are performed not from the viewpoint of mistuning problem but of flutter suppression in active sense. A computational method is developed as a multi-eigenvalue problem to analyse the characteristics of non-uniform cascade composed of blades with arbitrary natural frequencies. Numerical results are obtained for the several cases of blade arrangements mainly in compressor cascade which contains two kinds of blades having different natural frequencies, and some fundamental characteristics of flutter suppression effects, flutter modes and mode selection are made clear.
