Abstract

The utility model belongs to an air sailing boat which is propelled by an air propeller, mainly composed of a hull 3, an air propeller propelling system 1, a machine frame of an engine 10, a conduit or a guard net 14, a rudder 9, cabin seats 5, a driver's seat 11, a meter box 12 and a steel ring 13 which is used for tying a boat; the air propeller propelling system 1 is composed of an air propeller and an engine. 2-5 air lubrication grooves are formed at the bottom of the air sailing boat, because 3-6 antifriction cushions 7 are laid at the bottom part of the hull 3, and the bottom of the air sailing boat is divided longitudinally by the antifriction cushions 7. A bow part of the hull is filled with foam floating bodies 8; the cabin seats 5 are all buoyant seat boxes. The rudder 9 is an air-water double medium rudder, so that the air sailing boat has little resistance in sailing, and the abrasion resistance of the bottom of the air sailing boat is increased. The utility model has the advantages of good wind and wave resistance, stability, convenient operation, big effective load rate, etc. When the air sailing boat sails, the draft of the air sailing boat is smaller than 150 millimeters; small waves are made; the utility model can sail in the special regions, such as shallow water, marshes, snow and ice, etc.

Description

Air-lubricated hull

The utility model relate to a kind of with the measure that changes the intrinsic fluid dynamics feature of hull the special boats and ships of design-calculated, specifically a kind of air-lubricated hull that advances with air screw.

The existing air ship that advances with air screw, the hull bottom lower casing of " air-driving flying boat on water " introduced among air ship (Power PAC) that the U.S. black panther air shipping company that records as " high-speed ship " chapter in Britain's " Jian Shi yearbook " makes and the CN1095680A all is mild circular arc or W shape.Such hull when navigation hull bottom high-speed friction can take place with the water surface, produces bigger resistance, the easy simultaneously hull bottom that weares and teares.The hull of existing air ship is many to be made with metallic material or reinforced plastics outsourcing coating stainless steel plate, and weight of ship accounts for the ratio of ship total weight more than 35%, and the wind-proof and wave-proof stability is relatively poor.The existing set air rudder of air ship can only be used for that high speed is underway to turn to control, then can only control by the thrust of the control left and right sides screw propeller during lowsteaming to turn to, and maneuvering performance is poor.

The purpose of this utility model provide a kind of when navigation resistance little, hull bottom has fine wear resisting property, the wind-proof and wave-proof stability is good, the also very reliable air-lubricated hull (Air-LubricatedBoat) that advances with air screw easily of road-holding property during lowsteaming.

The purpose of this utility model is achieved in that air screw propulsion system 1, engine frame 10, conduit or grille guard 14, yaw rudder 9, cabin seat 5, driver's seat 11, instrument box 12, mooring that air-lubricated hull of the present utility model is made up of hull 3, air screw and driving engine constitute with steel loop 13.In order to reduce under sail the resistance that produces because of hull bottom and water surface friction, the utility model has laid 3～6 wear-resistant pads 7 in hull 3 bottoms, and vertically is segmented in the air lubrication groove 2 that hull bottom forms 2～5 roads by 7; In order to improve the wind-proof and wave-proof stability of hull, at ship bow part filled and process buoyancy aid 8, cabin seat 5 is the buoyancy seat-box; In order to ensure having when the lowsteaming good maneuvering performance, yaw rudder 9 to be designed to the two medium yaw rudders of air one water.

In addition, hull 3 of the present utility model has adopted the expanded letter design, and its length and width ratio is 2.4～2.7, so that air-lubricated hull obtains higher hydrodynamic(al) quality and good stability; Air screw has adopted the fine fiberglass blade of the carbon of 2～4 leaves and can make blade that the propeller hub that can arbitrarily adjust to best angle is arranged when mounted, being peripherally equipped with relative thickness at air screw is 6～12%, the ratio of diameter and pipe range is 2～4 wing section type conduit, and this has just improved angle of rake propulsion coefficient; The glass-felt plastic that hull 3 usefulness steel frames 4 and foam are filled out core constitutes, with the structural weight of reduction hull, and the intensity and the rigidity of increase hull, thereby the capacity weight amount of raising ship; On the anterior deck of hull 3, light hydraulic support 6 is housed also, is used for laying sun-shading rainproof canopy account; Air one aqueous medium yaw rudder preferably adopts NACA-0012 type wing section, and relative thickness is 12%, and length and width ratio is 3～5 yaw rudder, is positioned in the trailing edge of air screw.

The utility model compared with prior art, the advantage that has is: owing to laid wear-resistant pad alow, and formed the air lubrication groove, ship can be entered in the groove from the stem induced air when navigation, play lubricated hull, reduce the effect of running resistance,, improved the wear resisting property of hull bottom body simultaneously because of having avoided the direct friction of water and hull.The utility model air-lubricated hull is all filled water fashion at cabin 13% reserve buoyance, and the wind-proof and wave-proof stability is good, so the ship that can cannot not be referred to as heavyly.The weight of ship of this air-lubricated hull only accounts for about 20% of total weight, and capacity weight is 57% of a total weight, and the weight of ship of U.S.'s air ship (PowerPAC) of homotype accounts for more than 35% of total weight, and capacity weight is 400% of a total weight.This air-lubricated hull only needs the water rudder with air one aqueous medium yaw rudder partly come to control effectively when lowsteaming to turn to, have the good maneuvering performance of machine.The driving engine of this air-lubricated hull both can adopt aero-engine, can adopt vehicular engine again, selected for use flexibly.This air-lubricated hull manufacturing process is simple, need not mould, cheap, maintenance easily, absorb water less than 150 millimeters during navigation, and wave making is minimum, impacts little the narrow waters embankment, can be in super shoal water zone, special regional expert such as pasture and water district, Swampy Areas, ice and snow district sails, can be used for going on patrol, seize smugglers or smuggled goods, chase, speedily carry out rescue work, each side such as oil field shallow water operations, tourism traffic.
