Abstract
This new ship is characterized by that a rotatable floating system supports the ship, so that the rotation fo floating body can be used to diminish the water resistance against ship and realizes the utilization of water resistance to push the ship forward. The present invention can reduce the total resistance of ship greatly and enhance the performance of ship. it can also make the ship possessing amphibious character om water and land.
Description
The present invention relates to ship building industry, is a kind of boats and ships of new structure, is a kind of innovative technology of support pattern, propulsion mode and operating mode to boats and ships.
Present boats and ships can be divided into the buoyancy support type, i.e. displacement type is as passenger steamer, cargo barge and dynamically supported type, as glider, hydrofoil boat, air cushion oceangoing ship etc.The former is because its water resistance limits with the objective law that ship's speed is high power increase, and the speed of a ship or plane is difficult to improve.The latter be utilize fluid dynamic pressure lift with the most of of boats and ships or all lift dried up, reduce water resistance by the area of wetted surface that reduces boats and ships, thereby can reach the higher speed of a ship or plane.But the supporting power of dynamically supported type ship oceangoing ship a little less than, to having relatively high expectations of power plant, with regard to its effect that lowers water resistance, also have certain limitation because: when obtaining lift, must be cost one, to produce corresponding resistance; Still have the part that contacts with water when two, the dynamically supported type ship navigates by water, comprise propelling unit and operating control, this part still will produce the water resistance that becomes high power to increase with the speed of a ship or plane, and the air cushion of air cushion vehicle also can produce bigger wave making resistance; Three, dynamically supported type ship oceangoing ship all still is the buoyancy supporting when static state and lowsteaming, usually could produce enough lift with the supporting hull after will accelerating to the cooresponding speed of a ship or plane, it is reached slides or foil-borne, peak value in this its water resistance of transition term of voyage is all very high, and air cushion vehicle is kept air cushion also will consume very big power.
The objective of the invention is to, a kind of boats and ships of new structure are provided, create the boats and ships that a kind of high low speed all has the resistance performance better than existing ship, have higher propulsion coefficient and good maneuvering performance simultaneously, and can make institute's boatbuilding oceangoing ship have special in-use performances such as shallow water navigability and amphibious property, thereby develop a series of high-performance ships.
In order to achieve the above object, the present invention design is made of passenger-cargo boats and ships body of the carrying that comprises power system and common boats and ships other system and rotating buoying device system.The part of buoying device system immerses and produces buoyancy supporting boats and ships body in the water, the boats and ships body is on the water surface, when the buoying device system rotates, can change the immersion surface of buoying device system and the speed of relative movement of water, thereby lower or the elimination water resistance, the direction that also can change institute of buoying device system water resistance makes it become the thrust that advances boats and ships.The boats and ships body can be made into box-shaped or streamline-shaped.Power system is arranged on the boats and ships body, can be made up of driving engine, power-transfer clutch, multi-step transmissions, transmission shaft, drg and power chain.The buoying device link belt systems vertically rotates around the boats and ships body under power chain drives.If boats and ships navigate by water forward with speed V in hydrostatic among Fig. 1, the boats and ships body promptly travels forward with speed V, if this moment, buoying device link belt systems clockwise direction rotated, with regard to the immersion part of buoying device system, then be rearward to move with respect to the boats and ships body with the linear velocity of V1, by the vector resultant rule as can be known, determine that " the ship water is to the speed " of the boats and ships wetted surface of boats and ships water resistance also is the relative velocity of buoying device immersion part surface and water this moment, its value is V-V1, if V-V1>0, be that the rotation of buoying device system is slower, its immersion part still has forward speed with respect to water, then the water resistance of boats and ships lowers, if V-V1=0, then buoying device immersion part is zero with the speed of relative movement of water, the water resistance of boats and ships working direction is with complete obiteration at this moment, this moment boats and ships the power propulsion equipment internal friction that only need overcome the air resistance of boats and ships and mechanical system (comprising the buoying device system that rotates) just can to make boats and ships keep its value be that the speed of V is at the uniform velocity navigated by water, if V-V1<0, be V1>V, the buoying device system rotates and accelerates, this moment, water was identical with the ship's speed direction for the relative velocity of immersion buoying device, the direction of the water resistance that buoying device suffered of also promptly soaking is identical with ship course, the water resistance of buoying device of soaking this moment has become and has promoted the thrust that boats and ships advance, the air resistance when if this thrust equals the V speed of a ship or plane, boats and ships can be kept this speed of a ship or plane and at the uniform velocity navigate by water, so the present invention when subduing ship resistance, also can realize utilizing water resistance to advance the oceangoing ship oceangoing ship.
The present invention is because the design of its uniqueness, can eliminate the water resistance of boats and ships working direction theoretically fully, and can utilize propelling unit and the steering unit that turns buoying device system double as boats and ships, can save the propeller and the rudder gear of existing ship, can reduce the appendage drag of boats and ships, so the present invention's boats and ships has good resistance performance.Because the little rapidity and the better economy that will inevitably make boats and ships of its resistance.The present invention is for rotating the buoying device supporting, from the principle, the buoying device below both can be subjected to the hydraulic pressure effect, also can be subjected to the soil pressure effect, so the present invention has shallow water navigability and amphibious property, be convenient to the shoal, step on the sandy beach, but seaworthiness rivers,lakes and seas not only, can be made into the boats and ships that are fit to the use of beach marsh again, also can be made into amph two purpose vehicles, thereby enlarge the use field of boats and ships.
The propulsion system of the present invention's boats and ships also can adopt the various propulsion systems of existing ship, as the water propeller, air snail slurry and waterjet propulsion etc., power plant is the various power plants of available existing ship also, when adopting the propulsion mode of existing ship, the rotation of its buoying device system can be a passive type, promptly try hard to recommend its rotation by water resistance, this moment water resistance and buoying device system rolling friction total drag balance, so the good buoying device system of design has good drag-reduction effect, the manipulation of the present invention's boats and ships also can be adopted the various maneuverability patterns of existing ship, as water rudder, air rudder, or the directional control boats and ships of change water and air injection, but the present invention preferably adopts the rotating speed of control port and starboard buoying device to handle boats and ships, and therefore propelling of the present invention and maneuverability pattern can be made multiple choices according to actual conditions, and very big comformability is promptly arranged.Because the present invention has above-mentioned characteristics, the present invention can make the high-performance ship of a series of adaptation various uses.
