Abstract
The utility model relates to a front adjustable V-shaped surface piercing self stable hydrofoil slide boat used for overwater people carrying, transportation, travel and tourism. The body line of the utility model basically adopts planing boat line A V-shaped piercing self stable hydrofoil is positioned on the front portion of the midship of the boat body and an attack angle is adjustable in order to obtain the optimum lift-drag ratio and lifting force in different route speeds. The lifting force of the hydrofoil supports more than 60% weight of the boat. The hydrofoil structure mainly comprises a V-shaped hydrofoil, a ladder-shaped hydrofoil, a double V-shaped hydrofoil, etc. The longitudinal cross section of the hydrofoil is wing shape, arch shape or crescent shape. The boat combines the advantages of a planing boat and a hydrofoil boat to overcome the inherent disadvantages of a single boat. The overall performance of the utility model is better than that of the planing boat and the hydrofoil boat. The speed of the utility model is increased by 15%-30% than that of the planing boat and the vibration, the impact and the course stability of the utility model is better than that of the planing boat.
Description
Technical field
The utility model relates to high performance craft, refers in particular to a kind of waterborne mannedly, and the preposition adjustable v-type of being engaged in traffic, tourism and sightseeing cuts the face of striking from the water-stabilizing wing gliding-hydrofoil craft.
Technical background
Glider and hydrofoil boat are the important members in the high performance craft family, are all building in large quantities and are using both at home and abroad at present.
Glider slides at a high speed at the water surface, is that water buoyancy only supports the sub-fraction weight of ship by most weight of hydrodynamic force supporting ship.Its advantage is that speed is fast, and shortcoming is that vibration is big, attack is serious, course stability is poor, weight distribution is strict, and this shortcoming has seriously limited the weight layout of ship.
It is that the water lift that leans on hydrofoil to produce is held out the water surface fully with hull that hydrofoil boat navigates by water at a high speed at the water surface, its rapidity improves more than 15% than glider under same displacement and tractive power situation, it has overcome many shortcomings of glider, but propelling unit more complicated during its stall Datong District in wave, the cost height.
These shortcomings of glider and hydrofoil boat are by the decision of ship type, inevitably.
Summary of the invention
The purpose of this utility model provides a kind of glider and hydrofoil boat advantage taken into account, and the preposition adjustable v-type that overcomes its shortcoming cuts the face of striking from the water-stabilizing wing gliding-hydrofoil craft.
The technical program is that the hull line style adopts planing form substantially, and V-arrangement cuts the formula of drawing and is installed in hull midship front portion from water-stabilizing wing, and the angle of attack is adjustable, to obtain best 1ift-drag ratio and the lift under the different speed of a ship or plane, more than 60% of hydrofoil lift supporting hull weight.
The structure of hydrofoil mainly contains following three kinds of forms:
V-arrangement hydrofoil, trapezoidal hydrofoil, two V-arrangement hydrofoil
The vertical profile cross section of hydrofoil is airfoil or arc or crescent.
Its propulsion system is taked following layout at the gliding-hydrofoil craft of different types:
The gliding-hydrofoil craft of hull length below 8 meters should adopt outboard engine, and fully cavitating propeller advances or waterjet propulsion;
The gliding-hydrofoil craft of hull length more than 8 meters adopts said method to advance or adopts inboard outboard engine fully cavitating propeller to advance;
The gliding-hydrofoil craft of hull length more than 12 meters also can adopt the base fully cavitating propeller to advance except that adopting above-mentioned two kinds of methods propelling.
When ship speed reached certain speed, preceding hydrofoil was held out the water surface with the ship bow, thereby reached the drag reduction effect.At this moment, hull weight is by the hydrodynamic force supporting of hydrofoil lift and hull stern sub-fraction planing surface, and the hull weight of having only few part is by the supporting of water buoyancy, and hydrofoil lift has supported most of weight of hull.Along with the increase of ship speed, hydrofoil lift increases the ship bow and is lifted De Genggao, and hydrofoil is shared to such an extent that hull weight further strengthens, the stern planing surface support weight and support to such an extent that weight further reduces by water buoyancy, the total drag of ship also further reduces.
Its advantage is:
Gliding-hydrofoil craft combines the advantage of glider and hydrofoil boat, has overcome single ship type institute shortcoming inherently preferably, and its Combination property is better than glider and hydrofoil boat.The rapidity of gliding-hydrofoil craft has improved 15%～30% than glider, vibrates simultaneously, attack and course stability all had great improvement than glider.Though gliding-hydrofoil craft is poorer slightly than hydrofoil boat ground rapidity, it has overcome the shortcomings such as propelling unit complexity of hydrofoil boat; Gliding-hydrofoil craft can make the hull miniaturization, and hydrofoil boat then is difficult to accomplish owing to inborn problem.

The specific embodiment
As shown in Figure 1, the hull line style adopts planing form substantially; Can select for use glass-felt plastic (reinforced plastics fiber), aluminum alloy, ship steel or high intensity for ship steel as the hull material according to actual conditions.Hydrofoil material selection qualitative carbon steel, high strength steel, aluminum alloy, carbon fibre.
Hydrofoil is installed in hull midship front portion, and the angle of attack is adjustable, and adopt as Fig. 3, Fig. 4, shape shown in Figure 5 in hydrofoil (comprising stabilizer) cross section.
V-arrangement cuts the formula of drawing and mainly contains as Fig. 8, Fig. 9, three kinds of forms shown in Figure 10 from water-stabilizing wing:
V-arrangement hydrofoil, trapezoidal hydrofoil, two V-arrangement hydrofoil
Gliding-hydrofoil craft is the synthesis of glider and hydrofoil boat, and it has kept the feature of glider and hydrofoil boat technically.According to the real ships navigation of gliding-hydrofoil craft model experiment and 5.8 meters results, it promptly has the shortcoming that has overcome hydrofoil boat and glider with the approaching advantage of hydrofoil boat and glider again substantially.
