INCORPORATION OF FORWARD BLADE SWEEP IN THE NON-FREE VORTEX DESIGN METHOD OF AXIAL FLOW TURBOMACHINERY ROTORS

The paper presents a novel strategy for design of high-performance non-free vortex axial flow rotors with forward swept blades. The design methodology incorporates the determination of an optimum extent of forward blade sweep into the non-free vortex design methodology, considering the realistic three-dimensional blade-to-blade flow. The design methodology is to be completed with Computational Fluid Dynamics analysis and global measurements on the turbomachinery unit. A fan rotor design example is presented
