FIELD: mechanical engineering; high-speed centrifugal machines. SUBSTANCE: circular space made in impeller hub divides hub into inner and outer rings. Circular space is limited at one side by ring partition connecting inner and outer rings of hub, and at other side by rotating guide vane assembly or fairing. Ratio of width B of circular space and thickness H of partition is determined by inequality: $$$. EFFECT: enlarged operating capabilities. 3 dwg
