More Information
Summary:The invention discloses a high-speed supercavitation composite multi-hull boat and a method for reducing frictional resistance of the high-speed boat, and the high-speed supercavitation composite multi-hull boat is characterized by comprising an underwater submerged body, a water surface boat body and a connecting pillar for the underwater submerged body and the water surface boat body; a propulsion device seawater inlet is formed in the bow part of the underwater submerged body, a cavitator and a ventilation device are arranged on the bow shoulder part of the underwater submerged body, and a magnetofluid propeller is arranged on the stern part of the underwater submerged body; when the voyage volume Fourier number Frdelta is less than 2, the ventilation device generates gas to form gas film coverage on the surface of the underwater submerged body, so that the frictional resistance is reduced; when the volume Fourier number Frdelta is larger than or equal to 2, the ventilation device enables the surface of th
