Abstract

The utility model provides a straight body non-wave ship which only generates small wake flows in driving. A ship body does not comprise a superstructure, and the integral shape of the ship body is a straight cylinder. Steering of the ship is achieved through the inflow of one side of a ship head and the draining of the other side of a stern part.

Description

Straight body waveless ship

Affiliated technical field:

The utility model relates to the hull unit design that a kind of wave of generation reduces greatly.And its manoevreability is greatly improved.

Background technology:

All can produce wave during existing all foots, its wave started can be clapped to such an extent that rock whip is along the river directly rung.Its wave comes from the upstream face of fore and the huge wake flow of stern propeller ejection.Wave is harmful to, and the wave that canoe is likely given birth to by large ship is nearby thrown, and it is said that the wake flow that U.S.'s satellite also can produce according to Chinese submarine is followed the tracks of.The generation of wave needs kinetic energy, and this energy comes from driving engine.If do not produce wave while travelling, just saved the energy.

Simultaneously, existing all ships controls the alerting ability extreme difference.The rudder for ship of existing all ships all is arranged at stern.The automobile that is just trailing wheel as wheel flutter is to be difficult to drive.

Summary of the invention:

With the similar fusiform airflow design of all hulls through the ages far from each other be, hull of the present invention adopts the stretched design, that is to say that its hull (or Submarine) is moulded for straight cylinder, be that its all vertical outline lines all are parallel to each other, its fore and stern are just like two end faces of hollow tubular, be that its fore and stern are all the hollow mouth of pipe, the built-in pipe arranged in hull is communicated with fore and stern with reducing pipe.

In order to illustrate how the present invention realizes travelling without wave, and we first imagine the pipe that has to be submerged in water, if its tube wall is enough thin, when it is walked to dead ahead, the wave of its generation can be very little so.Situation now is: establishing the pipe speed of advance is v.If take pipe as object of reference, pipe head water flows into speed v, and pipe afterbody water flows out with speed v.If, but the water around take is object of reference, pipe head water is static, pipe afterbody water is also static.

The design's ship (ship) head is exactly its pipe head (whole fore is exactly a huge water inlet) so, and stern is exactly its pipe afterbody (whole stern is exactly a huge water outlet).If take hull as object of reference, fore water flows into speed v, enters the hull built-in pipe after reducing pipe, then after the axial-flow pump ejection is by reducing pipe, with speed v, flows out on the quarter.If, but the water around take is object of reference, fore section water is static, quarter of a ship water is also static.That is to say that the design's fore fore only can start very rips, stern also only can produce very little wake flow.

Modern ships, in order to reduce wave making resistance, is pursued its fleetline perfection, and the complexity of its hull design and manufacture is difficult to the imagination.And the design's hull adopts straight cylinder, for example hull adopts semicylinder, and submarine adopts cylinder, with regard to much more simply.

Another characteristics of the design are that the manoevreability of ship will improve greatly.Change the hand of rotation of axial-flow pump, can make fore become stern, stern becomes fore, that is to say and need not turn fore, just can pull up a horse and back open.The design on the bow port and starboard sets into hose nozzle, and on the quarter port and starboard sets out hose nozzle.For example make the water inlet of fore starboard, the water outlet of stern larboard, can make ship original place 360 degree turn-take, just as the car that has had a four-wheel steering.The improvement greatly of its manoevreability, very important for the urgent danger prevention (or militant naval vessels) of boats and ships.

The accompanying drawing explanation:

Accompanying drawing is only illustrated the vessel main body structure, ignores superstructure.

Fig. 1 is hull side facade sketch.

Fig. 2 is the boat body plane sketch

Fig. 3 is the positive facade sketch of hull

The specific embodiment:

Its whole fore is exactly a huge mouth of pipe, and current flow into eccentric reducer 1 at this, and the pipeline 3 of then flowing through is discharged through axial-flow pump 4, then flows out through reducing pipe 6.

For turning to of ship, at the built-in pipe water inlet, four-way cock 2 is set, to be communicated with the port and starboard coolant inlet pipe, at the built-in pipe water outlet, four-way cock 5 is set, to be communicated with the port and starboard coolant outlet pipe.When ship travels to dead ahead, it is the fore water inlet.If make the ship right-hand turning, four-way 5 valve dextrorotations are turn 90 degrees, become and only have the water inlet of fore starboard.

Claims

1. a straight body waveless ship, it is characterized in that: its do not comprise the agent structure of superstructure part moulded be stretched, be that its all vertical outline lines all are parallel to each other, its fore and stern are just like two end faces of hollow tubular, be that its fore and stern are all the hollow mouth of pipe, the built-in pipe arranged in hull is communicated with fore and stern with reducing pipe.

2. straight body waveless ship as claimed in claim 1, it is characterized in that: at the ship port and starboard, settle the pipeline for water inlet and draining, put within it on water pipe four-way cock is installed, be communicated with the pipeline for water inlet and draining that the ship port and starboard is settled, to realize turning to ship.
