Abstract

The present invention relates to an inflatable airship for water shipping. Inflatable propulsion replaces traditional ship propulsion, so that an inflatable airship can always travel above an air chamber; therefore, the structure of the airship is simplified, and the energy is saved by more than 50%. Compared with ships (including hovercrafts, hydrofoil crafts and other high-speed vessels) of the same tonnage and the same horsepower, the inflatable airship improves the speed by more than one time. The present invention is ideal in the aspects of safety, economy, rapidity, comfort, etc. The inflatable airship can be made into large, medium-sized and small, military and civil, passenger and freight transportation ships so as to be widely used in rivers, lakes and sea, particularly shallow rivers with rapid water currents.

Description

Pneumatic airship

What the present invention relates to is a kind of Pneumatic airship of shipping waterborne, particularly is applicable to the anxious river of the shallow stream of water.

The boats and ships of world's shipping waterborne at present, aspects such as resistance, the raising speed of a ship or plane, saving energy consumption are all not satisfactory overcoming.The air cushion vehicle of the pioneering technology that has come out is light because of load eventually, that energy consumption is high, wave is big etc. is former thereby its field of application is restricted.

The objective of the invention is to design a kind of Pneumatic airship for shipping waterborne, make that its speed of a ship or plane high energy consumption is few, the big wave of carrying capacity is little, reach idealized at aspects such as safety, economy, rapidity, traveling comforts, and can be made into large, medium and small, all kinds of passenger-cargo steamers of the army and the people and be widely used in rivers,lakes and seas, the anxious river of the shallow stream of water particularly.

The object of the present invention is achieved like this: in view of the density of water is 800 times of density of air, resistance also is 800 times of air, thereby forms the air cushion of one deck long-term use between Chuan Heshui, just can make the area of wetted surface of ship and resistance reduce more than 50%.The essential distinction of it and conventional air cushion vehicle is, saved the required great power of continuous charge buoyance lift, and corresponding deadweight, space, fuel and cost.Therefore, under the Pneumatic airship superstructure of the present invention, set catamaran hull bottom and this Pneumatic airship be the air chamber of a rigid structure of hull formation in last three orientation, front and back under water, and the air chamber below is by water-stop.Behind the water,, inflate to air chamber under the Pneumatic airship, Pneumatic airship is floated, cause Pneumatic airship to navigate by water on air chamber all the time by special device by the purpose made charging blower.Thereby realize purpose of the present invention.Wherein gordian technique is, the air chamber of Pneumatic airship is full of behind the air can long-term use, guarantees that Pneumatic airship navigates by water on air chamber all the time.

The advantage of Pneumatic airship of the present invention is to change traditional marine propuision system and be the inflation propulsion system, thereby ship structure is simplified, the manufacturing cost reduction.It with compare with the boats and ships of the speed of a ship or plane with load-carrying, can reduce cost and energy consumption about 50%.Because of air chamber is positioned under the water surface, Pneumatic airship had both utilized the big advantage of buoyancy of water carrying capacity, had utilized the high advantage of the little speed of a ship or plane of air resistance again.Therefore make the Pneumatic airship performance good, wave is little, and carrying capacity designs with the need, can be made into large, medium and small, all kinds of passenger and freight transportation boats and ships of the army and the people, and is widely used in rivers,lakes and seas, particularly the anxious river of the shallow stream of water.

Realize that Pneumatic airship best way of the present invention is: form superstructure by the driving platen 17 that mark is equipped with wave resistance rudder 4 by designed draft line 12 and buoyance lift floating line 13, freeboard 11, Windshield 3, ship top 14, both sides, steering disk 16 below; Place both sides under the superstructure respectively by catamaran hull bottom 15; Primary mover 5 is arranged between the catamaran hull bottom 15 from front to back successively, charging blower 6, non-return air valve 7 constitutes the inflation propulsion system; The hull of five positions surrounds an air chamber 8 on catamaran hull bottom 15 and the Pneumatic airship front and back under water, and the below of air chamber 8 is by water-stop, with the static pressure of draft, as the leak free maximum gas pressure; When not inflating, non-return air valve 7 SELF CL with assurance air chamber 8 pressure stabilitys, and float on the air chamber hull for a long time.Because air chamber has been full of air, just become the thrust of propelling when continuing inflation, it is characterized in that inflation power and tractive power unite two into one, thereby saved inflation power that jet propulsion simultaneously and waterjet propulsion unite two into one, thereby have improved the inflation propulsion coefficient.Pure jet propulsion and waterjet propulsion then are that gas-vapor mix proportion respectively is two special cases of zero.The place ahead of air chamber 8 is provided with and has the manipulation snifting valve 1 of handling jet valve rod 2, and the rear is provided with advance fumarole 18; When primary mover 5 drove charging blower 6 to air chamber 8 inflations, air chamber 8 pressure raise, and can make the Pneumatic airship hull be increased to buoyance lift floating line 13 positions, and make Pneumatic airship hull bottom and area of wetted surface on every side reduce more than 50%; After the air pressure of air chamber 8 surpasses hydrostatic pressure, the high density fog of gas-vapor mix is just from stern wave suppression plate 9 and the sliding corbel back slab 10 of stern envelope gas, via advance fumarole 18 ejections, when gas-vapor mix gas during from advance fumarole 18 ejection, Pneumatic airship advances, when gas-vapor mix gas when handling snifting valve 1 ejection, Pneumatic airship just as required, finish deceleration, suspend, fall back, or function such as turn to.Because charging blower 6 efficient height, can produce a large amount of current and air-flow hurdle afterbody sprays at a high speed, has the wave effect that gulps down that reduces the bow wave, so being inflation, the inflation propelling unit gulps down unrestrained propelling unit, it can guarantee Pneumatic airship navigation on air chamber 8 all the time, simultaneously be not afraid of collision in the hull because of being contained in again, the layout degree of freedom is wide, can arrange a lot of platforms all around, produce huge thrust, do not have additional resistance and thrust deduction again, can in the shallow water torrent, navigate by water, and can drag and hold transportation, form train waterborne and railway waterborne.Thereby Pneumatic airship is a kind of new transportation mode, and it can not compare with conventional air cushion vehicle in the traction transportation, is an obvious improvement.Pneumatic airship is when at a high speed navigation produces big first wave on the water, and wave resistance rudder 4 can reach and reduce wave, guarantees the purpose of other ships at safe navigation.Handle by steering disk 16, can reach self navigation purpose freely again.The catamaran stability is good, speed of a ship or plane height, and when low steaming did not need air cushion in stormy waves, Pneumatic airship just became and subtracts conventional Catamarans, can be at war with other displacement ships, has advantage equally.Because hull can be totally-enclosed, can in stormy waves, wear the wave navigation, thereby the seaworthiness district is wide.
