Description
Technical field
This utility model relates to navigation unit by water field, particularly relates to a kind of catamaran.
Background technology
Laterally connected firmly together by two single hulls and the ship constituted is referred to as catamaran, its advantage is: catamaran, owing to single hull is divided into two hulls, makes each hull taller and thinner, thus reduces wave making resistance, making it have the higher speed of a ship or plane, its speed of a ship or plane the most generally reaches 35-40 joint；Owing to the width ratio monohull of catamaran is much bigger, its stability is substantially better than monohull, has the ability bearing relatively strong winds wave；Catamaran not only has good maneuverability, but also has the features such as drag hump is inconspicuous, useful load is big.Based on these advantages, catamaran is gradually widely used in dual-use boats and ships.
More using requirement for meeting, catamaran is mostly progressively developing to high speed, and attempts developing to compound ship type for improving rapidity and sea-keeping.

Detailed description of the invention
As shown in Figures 1 and 2, a kind of catamaran that this utility model one embodiment provides, including cabin 10 and two single hulls 20,30.
Described cabin 10 has head end 11, tail end 12, left end 13, right-hand member 14, lower surface 15 and upper surface 16.The head end 11 in described cabin 10, tail end 12, left end 13, right-hand member 14, lower surface 15 and upper surface 16 enclose and set formation one driving space, it is possible to understand that this space is alternatively arranged as other purposes such as storage space.
The upper surface 16 in described cabin 10 is provided with hatch door 101 at head end 11.Hatch door 101 may be configured as transparent, in order to environment cabin 10 outside be can be observed in driving space.Hatch door 101 can be arranged on head end 11 and the junction of upper surface 16 in the way of employing is rotationally connected, it would however also be possible to employ the mode of push-and-pull is arranged.When using seal approach to prevent from navigating by water at the gap between hatch door 101 and upper surface 16, head end 11, water flows in cabin 10 from gap.
In certain embodiments, the head end 11 in cabin 10 may be alternatively provided as transparent on the whole.In cabin 10, being provided with operator seat 102 and operating board 103 at head end 11 and hatch door 101, operator seat 102 is taken for personnel, and operating board 103 can be used for handling this catamaran.
Two described single hulls 20,30 are arranged on the lower surface 15 in cabin 10 and respectively close to the left end 13 in cabin 10 and right-hand member 14.Set cavity in single hull 20,30, when this catamaran is placed in water, can be used for producing buoyancy.General, the water line that this catamaran is static when resting in water is on single hull 20,30, and the lower surface 15 in cabin 10 is positioned on the water surface.Thus during navigation, there is gap between lower surface 15 and the water surface in described cabin 10, be available for air-flow and pass through.
Described cabin 10 is wing along the cross section in navigation direction, and the head end 11 in described cabin 10 is more than tail end 12.As shown in Figure 2, head end 11 circle in cabin 10 is blunt, and tail end 12 is sharp-pointed, and the upper and lower surface 16,15 in described cabin 10 is the most curved, and upper surface 16 is protruding more, and lower surface 15 is relatively flat.When this catamaran navigates by water in the water surface, air-flow head-on flows through the upper and lower surface 16,15 in cabin 10, is divided into upper and lower two strands, behind cabin 10, overlaps into one again at tail end 12.Owing to the upper surface 16 in cabin 10 is protruding, flow through the channel narrows of the air-flow of upper surface 16.The principle of continuity according to air-flow and Bernoulli's theorem, the pressure of upper surface 16 is less than the pressure of lower surface 15, so that atmospheric pressure suffered by upper surface 16 is less, atmospheric pressure suffered by lower surface 15 is bigger, upper surface 16 becomes suction surface, and lower surface 15 becomes pressure face, and the pressure official post catamaran existed between upper and lower surface 16,15 produces dynamic lift during navigation, the resistance that hull navigates by water in water can be reduced, increase the speed of a ship or plane.
Further, the tail end 12 in described cabin 10 arranges wing flap 40.With reference to Fig. 3, wing flap 40 is arranged on tail end 12 and between two single hulls 20,30 of lower surface 15.Arranging electromotor (not shown) in single hull 20, the discharge directions of described waste pipe 21 is towards the lower surface of described wing flap 40.When electromotor ejection air-flow, the air-flow changed course that wing flap 40 forces electromotor to spray exists, and the counteracting force of this air-flow also can increase the dynamic lift of catamaran, and then reduces resistance, increases the speed of a ship or plane.
The single hull 20,30 of catamaran and cabin 10 etc. all use high-performance composite materials to make, and the tail gas that waste pipe 21 is discharged has the feature of high temperature, thus described wing flap 40 needs to use high-temperature resistant composite material.
In certain embodiments, it is respectively provided with electromotor in two described single hulls 20,30.Waste pipe 21 is all towards the lower surface of wing flap 40.Further, described wing flap 40 rotates the tail end 12 being arranged on described cabin 10.Wing flap 40, the angle of the relative water surface of scalable wing flap 40 are set by rotation, thus the air-flow adjusting electromotor ejection is applied to the counteracting force of wing flap 40, to coordinate dynamic lift and the catamaran balance on the water surface of catamaran.
As in figure 2 it is shown, the upper surface 16 in described cabin 10 is overall downward-sloping, lower surface 15 entirety in described cabin 10 is inclined upwardly.Upper surface 16 and lower surface 15 are the most curved.The cross section in cabin 10 is that biconvex is wing.Being appreciated that in other embodiments, the cross section in cabin 10 can also be rendered as the wing of other shapes, such as the plano-convex shown in Fig. 4 a is wing, concavo-convex wing shown in Fig. 4 b, or S-shaped shown in Fig. 4 c is wing etc..
With reference to Fig. 3, in certain embodiments, the upper surface 16 in described cabin 10 upwardly extends formation winglet 50 near the edge of left end 13 and right-hand member 14.Winglet 50 can be perpendicular to the flange of a strip of upper surface 16.During catamaran sailing, can be walked around by two ends, left and right owing to being positioned at the partial high pressure air-flow of cabin 10 lower surface 15 and arrive upper surface 16, cause swirling air stream.Swirling air stream can form resistance to navigation.And winglet 50 is formed at the edge of upper surface 16, and around winglet 50, producing crosscurrent, this air-flow is the most vertical with the air-flow flowing through upper surface 16, thus can weaken swirling air stream, to reduce resistance.Additionally, the side force produced by crosscurrent contains component forward thus produces corresponding thrust simultaneously.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, all it is considered to be the scope that this specification is recorded.
Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
