Described is a tandem turbine-blade cascade with at least two rows of blades disposed essentially one immediately behind the other in the rotor or stator of a turbo-engine, a power engine or other machine. The cascade of the second or following row of blades has a larger number of blades than the preceding row and its blades are non-uniformly, e.g. peridodically, distributed, thus enabling the pressure index and efficiency to be optimized.
