FIELD: mechanical engineering; gas-turbine engine compressors.
SUBSTANCE: proposed diffuser of centrifugal or diagonal-flow compressor has vanes whose pressure surfaces and suction faces have generatrices in form of curves of at least second order pointed by convexities to each other and smoothly conjugated with generatrices of trailing edges. Novelty is than trailing edge generatrices are of "sword" form being curved in circumferential direction.
EFFECT: reduced hydraulic losses in diffuser.
