L'Officina Marittima Bisognani uses the most modern methods of design. Our propellers are calculated using systematic series notes, and proprietary, developed over years of testing, also codes for calculating Lifting Line and Lifting Surface .

For thorough verification of the phenomena of interaction propeller-struts, propeller-rudder, propeller-hull, use commercial CFD codes, with which we study the response of new types of profiles against Cavitation Vibration due to pressure induced by the propeller on the hull ecc.

Our products are designed and developed on CAD of last generation, have solid modelers and surface modelers, that allow us to create the geometry of the calculated, and then subsequently on trial CAM stations for the tool path to go to the machine (numerically controlled milling CNC)
