1 IPS, the future for fast vessels 1 dec 2010

2 Save fuel and reduce environmental impact 2 dec 2010

3 Best efficiency with Contra Rotating propellers Double blade area means smaller prop diameter for same output No side forces from contra rotating propellers Half blade loading means half tip losses and minimized cavitation Less rotational speed means less noise and vibrations Contra- Rotating have no rotational losses Horizontal shaft increase the prop efficiency comp to angled shaft 3 dec 2010

4 EtaNet IPS Inboard performance system Highest net thrust efficiency with CR props and slender pod units 0,75 0,70 IPS pod, CR prop 0,65 0,60 Mixed flow WJ 0,55 Straight shaft, FPP 0, Boat Speed [knots] EtaNet=Eta0(1-Rapp/T) and were the appendage drag Rapp = Cd*0,5*Ro*D^2*V^2 EtaNet Eta0 Rapp T Cd Ro D V Net Thrust Efficiency Propeller efficiency Appendage drag Propeller thrust Drag coefficient Density of water Prop diameter Speed of vessel 4 dec 2010

5 Optimizing the shape of the pod units and the CR props 5 dec 2010 Improved circulation distribution ( front and rear propeller) Reduced specific loading New pitch distribution New camber distribution Modified blade tip 100% cancellation of swirl ing axial flow Pressure side cavitation on rear propeller eliminated
