N2 - With the idea of reducing the region of rotating cavitation by cutting back leading edge alternately and enhancing the stability of alternate blade cavitation, an analysis of steady cavitation on uneven chord cascade and its stability were made. The cavities on longer uncut blades are generally longer but it becomes shorter for a certain range of inlet cavitation number. This peculiar behavior is explained by the choking effect of cavities. It is also shown that the region with stable cavities can be extended and the onset region of rotating cavitation can be diminished by alternately cutting back the blades.
