| Abstract: | The different methods dealing with the boundary condition for lifting surface method of pro-peller design were analyzed.A design example by using the different simplified and the exact three-dimensional boundary condition has been carried out.Through the comparisons between the calculated results and the analysis,some conclusions related to reasonable treatments on boundary condition for prac-tical application are drawn.It concludes that radial component of velocity and radial gradient of geometry can play significant role and influence the design results at certain practical design conditions,such as highly skewed,raked,or rather rapidly variable pitched propeller,or the case with significant radial inflow. |
