The chart inventory: totally four pages, 13 width of cloth figure.
Concrete Method Of Accomplishment: the restraining tubing boat fore is designed to, see figure one, figure two, below the floating line (seeing figure one, 1) is a confinement tube, the constraint of fore water is lived, confinement tube water inlet (seeing figure one, 2) two side can maintain an equal level with ship side by (referring to the routine flat-bottomed boat in back), and outstanding (the seeing below routine sharp bottom boat) outshot of also comparable ship side is parallel with ship side.Can maintain an equal level with hull bottom at the bottom of the confinement tube water inlet pipe, also can be lower than hull bottom, but must not be higher than hull bottom and wide less than ship two sides of a ship.Confinement tube water inlet place outside tube wall (seeing figure three, 1) to inner tubal wall (seeing figure three, 2) is introversion.The ship side floating line is following to be dull and stereotyped extremely near the stern place, to prevent to form wave making resistance.The high speed of restraining tubing boat, the power that air draught consumed will increase, above and the hull superstructure of fore floating line is designed to the shape that reduces the power that air draught consumes and is as the criterion, as stream line pattern, it is good shape that the hull afterbody is designed to reduce eddy resistance, as streamline contour, to reduce eddy resistance.Fore constraint water rearward (sees figure five, 4) by water pump or miscellaneous equipment or proceeds posterolateral is discharged (seeing figure one, 5 figure six, 3).Dewatering pump is the most suitable with centrifugal pump in existing water pump, also can use other water pump and equipment water in the confinement tube rearward or proceeds posterolateral discharge.Fore water prolongs confinement tube from the confinement tube water inlet and enters the centrifugal pump water inlet, and the garden type that the confinement tube smooth variation becomes to equate with water pump entry actinal surface is to reduce eddy loss.Be trapezoidal being contracted to as confinement tube and the time be varied to the ellipse garden shape that equates with water pump water inlet area, change into garden shape by the deformation of ellipse garden again near the place with water pump water inlet area.The confinement tube water inlet is a square, directly is varied to garden shape.By pump handle constraint water rearward or proceeds posterolateral discharge, form thrust forward simultaneously.The dewatering pump of the draining of fore constraint water can be a pump, also can be several pumps.According to the quantity and the water intake mode of water pump, decision is divided into confinement tube several, several water pumps, according to the displacement of each water pump, determine each confinement tube water inlet area.The fore confinement tube is separated into several minutes beam tubes, separator of battery plates water inlet place, by the centre to each minute confinement tube introversion (seeing figure four, 1 to 2).Hull power thrust forward, the pressure of water in the formation confinement tube.The power of hull forward thrust can advance by the thrust that the draining of fore dewatering pump forms simultaneously is single.The pressure of water can reduce the power that water pump consumes in the confinement tube of the thrust formation that forms simultaneously.Also can advance by fore power thrust and two driving of stern power (seeing figure one, 3) thrust.Two driving restraining tubing boat afterbody engine thrust are put, and thrust is big, can reduce the power that fore power water pump high-speed operation is consumed better.Be more suitable in the high speed restraining tubing boat.The two driving device equipment of fore power list impelling ratio are few, reduced the complexity of mechanical equipment.During actual shipbuilding and navigation are used, can be according to the degree of utilization of the speed of a ship or plane, effective power, decision such as the complexity of power plant advances or two propelling for single.Water is the water that pressure is arranged, speed is arranged in the confinement tube, and the water that enters water pump is the water that pressure is arranged, speed is arranged, and can strengthen the water inlet area of water pump like this.Make pressure have the water of speed under the water pump action of centrifugal force, still can all discharge, increased the displacement of water pump.The restraining tubing boat speed of a ship or plane gulps down the water speed decision by the confinement tube water inlet, has overcome the wave making resistance influence, and the raising of effective power, for the speed of a ship or plane that improves Vessel of Displacement provides the extremely wide prospect that expands.The width of ship type and the degree of depth are not influencing the speed of a ship or plane, can make ship form coefficient try one's best greatly, can roll up the width and the degree of depth of ship type, increase displacement and load carrying ability.Reduce the shipbuilding material.Reduce the shipbuilding cost.The high speed of restraining tubing boat, anterior and both sides, open-air pedestrian deck will be provided with the enclosure wall that keeps out the wind, so that the people can be movable above deck, reach at the speed of a ship or plane and to be provided with the enclosure wall people of keeping out the wind can not be movable above deck the time, and the deck upper design becomes to seal not busy state.The high speed of restraining tubing boat, having very big wind energy can utilize, and wind machine (seeing figure one, 4) is set on hull top drives generator for
