In this paper, the approach for the contrarotating propeller parametrization modelling is provided based on the APDL language. Contrarotating propeller's parametrization modelling have several advantageous for the designers. The designers only need input some parameters, then the contrarotating propellers model could be produced automatically. Finally, this models are input into ANSYS to carry on automatically the strength analysis, and input into FLUENT to carry on the fluid analysis. It has saved the analysis efficience and has the very useful values.
