Geometry for the Design of Wageningen B-Series Propellers

Some time ago we had a request from a propeller designer to come up with an easy-to-use parametric geometry model in CAESES® for the Wageningen B-Series. There is a mathematical definition published for setting up such a marine ship propeller with some inputs (e.g. area ratio, number of blades, pitch/rake/skew data as well as leading and trailing edge information) to create a set of 2D profiles. These profiles are defined at specific radial locations. In order to generate a parametric blade surface from this radii-based information, we wrapped everything up in a feature definition, transformed them into the 3D space using a cylindrical transformation and finally skinned the 3D sections.

The result is given in the following short demo video where some parameters are changed interactively:

 

More Information

This parametric propeller model is directly available for productive use. All parameters can be controlled by optimization strategies for fully automated studies. Since the profile information is wrapped in a feature definition, you also have the option to access and modify this model, to further customize it to your needs. We can also quickly generate a STEP file for you based on your specifications for a B-Series propeller. Please do not hesitate to get in touch with us if you are interested in it:
