Test problem of the flow modeling in axial compressor cascades
Авіаційно-космічна техніка та технологія, 2022 The flow of gas in the flow path of a gas turbine engine (GTE) is accompanied by a rather complex phenomenon. These are a three-dimensional boundary layer, an incoming vortex, a paired vortex, flow turbulence, aerodynamic wakes behind the trailing edge ...

The Torsional Stability of a Compressor Cascade [PDF]
Volume 5: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education; IGTI Scholar Award; General, 1991 This paper includes new experimental data on the torsional stability of a compressor or fan type of blade row. This data is linked in with published material to form a three dimensional figure describing the stability of such rows. The data is then discussed by considering relative values of influence coefficients and some of the trends in the ...
