Threedimensional flow in transonic axial compressor blade rows
Abstract
Recent developments in the threedimensional aerodynamic theory of inviscid flow in transonic axial compressors are reviewed. Emphasis is placed on the newly completed lifting surface theory of a transonic ducted rotor. The relationship between the lifting surface theory and axisymmetric throughtheories of turbomachines is illustrated; a few examples of the additional information obtainable from the new theory are then given. Quasitwodimensional cascade theory can also be extracted from the present analysis and the relevance of cascade theory to the actual threedimensional problem assessed. Details are reported elsewhere, but some of the qualitative conclusions are discussed here. Even moderate departure from uniform spanwise loading of the rotor blades, for example, leads to a rather profound influence of the downstream wakes, suggesting the need for considerable care in applying cascade data on a direct quasitwodimensional basis.
