Aerospace Instrument-Making Annotation << Back Aerodynamics of the combustor diffuser of current-technology turbine engines Veretennikov S.V., Piralishvili Sh.A., Fasil Ali Gugsa Results of an experimental research of working process of the tear-off diffuser of turbine engines combustor are submitted. Influence of the basic regime and geometrical parameters on its efficiency is shown. Results of experimental and numerical research of aerodynamics hybrid diffuser for the modern unemissive radial-step turbine engines combustor are resulted. Influence of the flux amount of the sucked out air on the diffuser efficiency is determined.
