Longitudinal flow transition type semi-gliding yacht

Abstract

The invention belongs to the technical field of high-performance ships, and relates to a gliding yacht type, in particular to a longitudinal flow transition type semi-gliding yacht. When the longitudinal flow transition type semi-gliding yacht sails at a relative high speed during the transition state, air enters from a horn opening of the yacht bow under the punching effect and then is mixed withwater flow of the yacht bottom to form a water and air mixture, and the effects of lubricating and resistance reducing are achieved. The yacht side of the straight wall reduces wave making of a yachtbody, and the effect of reducing the pressure resistance is achieved. Compared with a channel gliding yacht, the wet surface area is small when the yacht sails at medium and low speed, and thus the friction resistance is relatively small. Compared with a single-body gliding yacht, the yacht has the wider deck area for loading, meanwhile, the bottom has a certain transverse oblique ascending angle, equally, the deep V degree of the bottom of the gliding yacht is increased, rocking and panting of the gliding yacht in waves are reduced beneficially, and the shipping-direction stability is improved.

Description

technical field [0001] The invention belongs to the technical field of high-performance ships, and relates to a planing boat type, in particular to a longitudinal flow transitional semi-planing boat. Background technique [0002] At present, high-performance ships are widely used in military and civilian applications due to their fast and flexible characteristics. All kinds of high-performance ships have unique advantages and disadvantages: full-cushion hovercrafts have superior speed, good maneuverability in still water, and It is less affected by water depth, tide and coastal seabed slope, but this type of boat has poor seakeeping, low economy, and relatively high construction and maintenance costs; hydrofoil boats have superior seaworthiness, but in offshore, Boundary rivers and other watersheds have deep drafts and poor resistance performance; conventional single-hull planing boats have been fully developed, but with a small deck area, the speed, seaworthiness and maneuv...

Problems solved by technology

[0004] The purpose of the present invention is to combine the advantages of the existing planing boats, and at the same time, aiming at the problem that the existing boats have high resistance in the middle and low speed sailing state, it is proposed that the wave making in the transitional sailing stage is small, and at the same time, the gas-liquid mixed layer can be used to reduce the frictional resistance A longitudinal flow transitional semi-planing craft
