RESEARCH ON RAPID GENERATION OF DUCTED PROPELLER MODEL AND ITS OPEN WATER PERFORMANCE

Xianlong Liu, Song Tang

ABSTRACT: Using coordinate transformation method, two-dimensional blade section of ducted propeller is converted to three-dimensional coordinate system. The ducted propeller is built by NURBS surface. The generation of the ducted propeller is based on AutoCAD and Excel secondary development by Visual Basic 6.0. There, the ducted propeller model can be parameterized by one click. Calculating the thrust and torque values of ducted propeller at different speed coefficients by RNGk − ε turbulence model equation.
