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:



Online Propeller Tool

We have also released a new online propeller tool that generates solid geometry for the Wageningen B-Series. This tool is based on CAESES® and comes with two different possibilities (web apps) to generate a propeller. The final geometry can be downloaded as STL or STEP file. Check it out and – please don’t forget to leave your feedback there!

    Dear Caeses Team,

    I am glad that the tool is very useful to B-Series propellers. However, there are certain propellers which also has skew parameter and rake as well.

    Could you tell, how well those aspects can be taken care during the modelling the marine propeller?
