abstract

An application of tip devices in the form of turning (adjustable) tip additional blades is rather effective means of influence on compressor performance due to change of fluid conditions in the region of rotating blade tips. The paper presents main results of tests of turning tip additional blades of two types. Firstly tip elements of rotating blades were substituted for turning tip additional blades at full length of the blade chord projection. While testing of these “large” additional blades with variable stagger angles, a significant shift of rotor performance curve to lower values of flow coefficients was observed, but this positive effect was accompanied by a great rotor peak efficiency drop. Then the similar turning tip additional blades were arranged only in the inlet part of rotating blades (“short” additional blades). Testing was done under condition of variable stagger angles in common with change of axial clearance between blade elements. As a result of these two parameters combination, maximum extension of stable operating range was found. And the important fact is that the rotor efficiency drop was relatively small after sharpening the inlet edges of the succeeding elements of rotating blades.
