Abstract : Results are presented of experimental research of compressor stages in which the angle of the setting of the input edges of the diffusor apparatus changes in accordance with the change in the direction of the flow in passing from one mode of operation to another. The use of the turning diffusor apparatus assures considerable reduction in the losses in the noncomputed modes of operation and consequently a steeper efficiency characteristic and higher pressure furnished by the compressor. Especially it can prove to be effective to use turning diffusors in machines intended for working in a broad range of change in modes of operation. The complex method of regulation in which the diffusor turning apparatus is used in combination with any of the method of regulating followed in practice (choking down the suction, whirling the flow before the rotor, or changing the number of revolutions) can considerably improve the economy of the regulated machine.
