Detailed description of the invention

As shown in Figures 1 and 2, a kind of catamaran that one embodiment of the invention 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 near head end 11 place.Hatch door 101 may be configured as transparent, in order to environment cabin 10 outside be can be observed driving in space.Hatch door 101 can adopt the mode being rotationally connected to be arranged on head end 11 and the junction of upper surface 16, it would however also be possible to employ the mode of push-and-pull is arranged.When gap place between hatch door 101 and upper surface 16, head end 11 adopts seal approach to prevent from navigating by water, 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, head end 11 and hatch door 101 place being provided with operator seat 102 and operating board 103, 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 in navigation process, between lower surface 15 and the water surface in described cabin 10, there is gap, it is available for air-flow and passes 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 all 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 in navigation process, 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 sprays air-flow, wing flap 40 forces the air-flow changed course that electromotor sprays to exist, 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 adopt high-performance composite materials to make, and the tail gas that waste pipe 21 discharges has the feature of high temperature, thus described wing flap 40 needs to adopt 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.By rotating, wing flap 40 is set, the angle of the relative water surface of scalable wing flap 40, 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 all 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, for instance the plano-convex shown in Fig. 4 a is wing, concavo-convex wing shown in Fig. 4 b, or S shape 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.In catamaran sailing process, the partial high pressure air-flow owing to being positioned at cabin 10 lower surface 15 can be walked around by two ends, left and right and arrive upper surface 16, causes swirling air stream.Navigation can be formed resistance by swirling air stream.And winglet 50 is formed at the edge of upper surface 16, and around winglet 50, producing crosscurrent, this air-flow is generally 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 is absent from contradiction, all it is considered to be the scope that this specification is recorded.

Embodiment described above only have expressed the several embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to making some deformation and improvement, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
