Supercavitating SWATH designs has been engineered by among other Japanese universities and defence academies, Greece research centre and Juliet Marine Systems in cooperation with US Navy.
InSvivia Technologies’ patented cavitator body makes a gyroscopic- and radial-interaction-stabilized supercavitating SWATH with significantly increased effects. The patent makes multiple fuel-reduction effects as (1) further minimized waterplane area, (2) further maximized gas isolation, (3) reduced pressures and subsea wave-making resistance, and (4) a hybrid-solution without complications.
A SWATH (Small Waterplane Area Twin Hull), minimizes the waterplane area and cuts the water surface unaffected of waves and with minimal wave-making resistance. The general SWATH-principle works like two submarines driving beneath the waves that carrying a platform above the waves, with a maintained horizontal position.
– A SWATH is like a submarine-borne platform.
The general SWATH-design has three big benefits;
Reduced (1) pitching, (2) bending momentums and (3) wave-making resistance.
Unfortunately, the SWATH up to doubles the wet surface compared to other hull shapes, and it needs further stabilization. Traditionally, several stabilizer-systems has been used for stabilization, as fins, foils and conventional gyroscopes. Lowering hull has also been used for stabilization in static positions with additionally reduction of the increased depth.
Supercavitating SWATH’s remove big parts of the increased wet surface, but can also need furthermore stabilization than conventional SWATH’s.
InSvivia’s combination of gyroscopic-rotating hulls, radial water-interaction lift and lowering hull enables further waterplane area reduction for further minimized wave-making resistance, pitching and bending momentums.
