The Multipulsion®

With our patented Multipulsion® principle, we created a balanced, non-uniform propeller. By combining different approaches for the variation of the blade geometry with methods of compensating for the imbalances thus caused, Promarin designed a completely new propeller. Its behaviour was extensively simulated using our most modern processor cluster. The simulations exceeded expectations and showed that the Multipulsion® successfully combines multiple effects to reduce noise. Not only does the Multipulsion® eliminate harmful harmonics, it also smears the vortices that normal propellers develop at their blades tips, which can cause destructive cavitation and extreme noise. These improvements do not come at the cost of a higher fuel consumption because the Multipulsion® is still a propeller in the classical sense – just more intelligently made.
