Abstract : To reduce the weight and complexity, individual stages of avia gas turbines are plannned for speeds of sound. The effectiveness of stages should not decrease here. The causes are discussed of loss increases in blade rims at these velocities and mentioned are the requirements, which must be observed during the planning of blades. From the measurement results of dividing blade lattices are visual the difficulties, with which the preparation of blade lattices encounters with low losses when flowing at sonic speed and also given are ways for their elimination.
