J. Talbotec, M. Vernet
Snecma, France

Keywords: counter-rotating fan, aerodynamics, fan design, fan aerodynamic tests

The goal of this paper is to present the design logic that has driven CRTF baseline and variants, trying to highlight the major differences with conventional fans. We will also focus on experimental results analysis and how they are matching CFD based performances prediction (performed before manufacturing CRTF blades).
