| | New design revisions are developed using the latest Computational Fluid Dynamics software for boat (CFD) and tested for strength using Finite Element Analysis (FEA). CFD is now capable of accurately predicting incremental design improvements, and offers a significant time saving to evolving propulsion designs using multiple models and full scale trials. Validation of propeller designs is of particular importance to finalise the design process. All proposed new designs are tested in a cavitation tunnel using a scale model, and then trialed on a full scale vessel to check other performance attributes such as manoeuvrability and acceleration. Finally, the predicted improvement in efficiency and/or smoothness is verified with back to back trials on the full scale vessel using the current and proposed propeller designs. | VEEM's primary test vessel is a 64ft sport fisher powered by two off 2400HP+ engines for boats. This vessel is specifically used for validating new propeller designs operating in the 30 to 50+ knot bracket. VEEM's commitment to research and development ensures you are purchasing a cutting edge product. | |
