Abstract
The invention relates to a high-speed ship on the basis of double inclinable screw propellers, and belongs to the technical field of ship propulsion. The double inclinable screw propellers are symmetrically distributed on the middle upper portion of the high-speed ship and can be reasonably inclined at certain angles, so that propulsion force has upward component force and component force in an advancing direction. The upward component force overcomes a part of the gravity of the high-speed ship, the immersion depth of the ship is reduced, and the resistance on the ship is decreased; and the component force in the advancing direction pushes the ship to advance. A tail fin screw propeller is arranged at the tail of the ship, the inclination position of the tail fin screw propeller can be changed, and the tail fin screw propeller can be matched with the front double screw propellers in an equilibrium manner, so that the ship can run stably. The high-speed ship overcomes shortcomings of poor stability of equilibrium of a common high-speed ship and poor mobility of the common high-speed ship, and has the advantages of capability of running at a high speed, excellent mobility and stability of equilibrium, and the like. Besides, the high-speed ship is low in cost and has popularization value.
Description
Technical field
The invention belongs to the propulsion of ship technical field, relate to speedboat fast and the technical scheme of smooth-ride, particularly a kind of plug-in screw propulsion apparatus of capable of adjusting installation angles and the scheme of spiral propeller balanced distribution thereof at sea.
Background technology
Over thousands of years, although boats and ships have a great development, be unable to do without Archimedes principle always, rely on all the time quiet buoyancy supporting ship heavy.The density of water approximately is 800 times of air, and resistance also will be airborne 800 times under kindred circumstances.And ship navigates by water at water air interface, can rise wave, and this resistance that is caused by wave making generally is directly proportional with 6 powers of the speed of a ship or plane, and the speed of a ship or plane that therefore improves boats and ships truly has difficulty.Because the biggest factor that affects displacement formula water surface ship speed is wave making resistance, therefore the design of nearly all high speed vessel all manages to reduce the area of contact with empty water critical surface, perhaps avoid the therewith contact of critical surface.For example hydrofoil boat is that hull is floated on the surface of the water, and Submarine then is to dive beneath the water to avoid wave making resistance.
In existing boats and ships, similar with regard to glider and hydrofoil boat and the present invention.When glider was run at high speed, fore raised up, and relied on hull bottom with relative impulse force between the water surface ship to be held up, because hull bottom is little with water surface contact surface, the resistance of water also just reduces, so ship can reach high speed.But it also has following defective, because ship's speed is high, fore is also higher, and chaufeur has certain danger.Can only make canoe and can not make large ship.Because fore is high, itself fears stormy waves, easily shipwreck in billow.Hydrofoil boat is divided into and shallowly soaks formula, cuts the formula of drawing, deeply soaks the formula hydrofoil boat.Wherein best with the performance of deeply soaking the formula hydrofoil boat with automatic balance control system.Its defective has: ship must accelerate to certain speed just can make the ship draft reduce, and hull slows down when falling, and other resistances of wave making resistance and water sharply increase, and are very large to the impact of ship.Because the ship in the process of moving hydrofoil load of bearing changes, so the lift that hydrofoil produces also changes, this just must have automatic balance control system to control the hydrofoil elevation angle, thereby the lift that provides is provided, to reach the requirement that makes the ship balance.And use on this balance control system and the aircraft similar, its cost costliness very.And high speed vessel has when billow the poor and poor common problem of maneuverability of stability of equilibrium.In the evolution of modern ship, improve gait of march, increase the ship riding stability, improve the emphasis that its maneuvering performance always is research.The progress of modern spiral propeller technology and Eltec provides theoretical basis and Technical Reference for high speed and stable the travelling of ship.
Summary of the invention
In order to overcome deficiency of the prior art, the objective of the invention is to provide a kind of based on the angle of rake high speed vessel of tiltable double helix.This ship problem that weighing apparatus is stable, maneuverability is poor and cost is high that has much difficulty in healing in the time of solving the high speed of a ship or plane, high speed in the above-mentioned technology.Change the draft of ship by the tiltable double helix propelling unit of this forward quarter left-right symmetric distribution and the cooperation of empennage spiral propeller, thereby change the suffered wave making resistance of hull.Therefore, hull can be realized the purpose of running at high speed on the water surface.By regulating the empennage spiral propeller realizing turning to of hull, and empennage spiral propeller and the angle of rake cooperation of anterior double helix, make ship can in traveling process, keep the stability of equilibrium of getting well and high maneuvering performance.
Comprise in order to reach the technical scheme that purpose of the present invention takes: this high speed vessel comprise hull 1, anterior symmetrical double helix propelling unit 3 and 3 ', empennage spiral propeller 5.Main shaft 2 is at the place, position, middle and upper part of hull 1, the spiral propeller 3 and 3 that left-right symmetric distributes ' be connected with main shaft 2.By the rotation of drive shaft 2 regulate double helix propelling unit 3 and 3 ' angle of inclination a.Because the lift that exists angle of inclination a, the angle of rake thrust of double helix can be decomposed into propulsive force forward and make progress.Lift upwards overcomes the gravity of hull part, thereby reduces the area of contact of hull and aqueous vapor face, namely reduces draft H, therefore can significantly reduce the suffered wave making resistance of hull.Can rationally change angle of inclination a in addition, the thrust that the double helix propelling unit is produced has downward component, and can increase the displacement of ship this moment, thereby increases draft H, so can be when the wind and waves stable navigation of this high speed vessel.The thrust of working direction then overcomes resistance to be made the ship acceleration and reaches at a high speed navigation.At the afterbody of hull, the afterbody that is installed in hull 1 that rotating shaft 4 is vertical, empennage spiral propeller 5 is connected with rotating shaft 4, consists of empennage screw propulsion apparatus.The angle that rotating shaft 4 is rotated is c.Empennage spiral propeller 5 can be around point of connection at the rotating shaft 4 angle b certain with the rotation with in surface at empennage spiral propeller 5 axis places.By reasonable change angle c and b, realize that the thrust direction of empennage spiral propeller 5 changes.This empennage screw propulsion apparatus is realized the turning function of ship and the effect of configuration balance.Simultaneously, the double helix propelling unit of the symmetrical branch in forward quarter and 3 balanced distribution of empennage spiral propeller and reasonably be used in conjunction with can improve balance and stability that high speed vessel travels.
Beneficial effect of the present invention is, the draft H that the tilting double helix propelling unit of fore-body symmetry can reduce hull namely reduces displacement, make ship can be in the sea stormy waves hour realize running at high speed.Simultaneously when stormy waves is larger, regulate the angle of inclination of double helix propelling unit and empennage spiral propeller, increase draft H, make travelling that ship can be stable.In addition, by increasing power, hull is sunk down under water fully travel, reach the effect of hiding at sea.Empennage screw propulsion apparatus not only can play steering-effecting, also plays and anterior double helix propeller system collocation, realizes that high speed vessel keeps the effect of stable and balance under steam.The triangle balance of 3 spiral propellers distributes and can make ship reach high maneuvering performance and stability of equilibrium.Simultaneously, the collocation of three spiral propellers is used, so that this gear has multiple motoring condition.Compare with hydrofoil boat, this high speed vessel has not only overcome the defective of hydrofoil boat, and manufacturing cost is less.
