摘要：

In designing the last stages of high-capacity steam turbines, of importance is the choice of relative pitch of moving blade and cascades in the tip zone. Moving blade dimensions in these stages are usually restricted by stresses to failure. The authors consider the case of subsonic velocities and have conducted theoretical and experimental investigations into standard cascades of profiles of tip sections. Two-dimensional cascades were tested experimentally in air and in superheated steam. For calculation, the procedure used was the nonsteady finite-difference method of large particles in gas dynamics.
