Abstract

A design scheme of a military ship capable of rapidly turning. A can short-range turn rapidly, military naval vessel with strongest fast turn and dodge ability, add 2 groups of very flexible propellers underwater on both sides of the hull under the same condition with other naval vessels, front left back right or front right back left are a pack, do not need the drive shaft but each use a motor to be able to, start the necessary pack while turning, push the hull forward and backward to the opposite direction and can keep the hull balanced, steady; the collision of other ships can be avoided rapidly, the attack of enemy missiles can be avoided rapidly, the direction can be adjusted rapidly to correspond to the upwind or downwind when the enemy missiles encounter typhoons, and submerged reefs can also be avoided rapidly. When the ship body inclines to one side, the front propeller and the rear propeller on the side can be started to be balanced temporarily.

Description

Design scheme of military ship capable of turning rapidly

The technical field is as follows: the method is suitable for large ships such as aircraft carriers, guard ships, patrol ships, warships, sea police ships and the like, is also suitable for civil large ships and particularly various military ships such as aircraft carriers, cruise ships and sea police ships, and needs to turn or fall off or attack enemy ships or avoid collision with other ships or adjust directions to deal with emergency turns such as typhoons, reefs and the like in order to quickly avoid the attack of enemy missiles or avoid the collision of enemy ships. The submerged reef needs to be avoided urgently when the submerged reef is discovered, and the civil ship or military ship can turn to upwind or downwind in time when encountering typhoons or hurricanes in the sea.

Secondly, the technical background is as follows: at present, all ships in the world only have the function of pushing forwards or backing backwards quickly, and the best mode is that double propellers are arranged behind the ships, one is pushed forwards and the other is backed (reversed) when the ships turn; this method of turning is too slow, requiring tens of meters, and a large vessel may need hundreds or thousands of meters or kilometers to turn over because of the large mass of the vessel and the large inertia. On land, when a vehicle of several tons or dozens of tons advances at a constant speed, the vehicle can be braked by several meters or more than ten meters by virtue of the strong friction of a road; under the conditions of no large friction force and small resistance, the giant wheel of thousands of tons and tens of thousands of tons has large inertia; in addition, the ratio of the length to the width of the ship body is too large, almost seven to eight to one, and the ship is difficult to turn quickly; at present, China does not have the function ship capable of quickly turning and turning around, and the most advanced U.S. in the world does not have the design, because 5 times of collision accidents with civil ships occur in the army within one year, 17 army death accidents and serious damage to ships are caused, particularly, the Mkaesi in the U.S. are seriously damaged, and because the prior art has two propellers or more propellers at the back of the U.S. at most. During turning, the ship is pushed forwards and reversely turned backwards, and a ship body with the length of tens of meters or hundreds of meters is difficult to turn over or turn around, is very stiff and cannot turn over or turn around in a short distance. The ship running in the sea needs to fast turn to deal with typhoons and hurricanes, because the ship can only resist the thrust of the typhoons and hurricanes in the downwind or the upwind; there is therefore a need for an arrangement for a quick turn device for sheltering from submerged reefs without damaging the hull of the vessel.

Thirdly, the invention content: different from the prior art: 1, two ends of a ship body are respectively provided with 1 group of screw propellers, each group can be two or four or more screw propellers, the screw propellers can be stretched and contracted, are contracted in the ship body when in navigation and are covered by sliding covers, the navigation is not influenced, the sliding covers are quickly opened when the ship needs to turn, the screw propellers extend out, and form a group (shown in figure 1) in the opposite direction 1 from the front to the back, namely form a group from the front left to the back right and from the front right to the back left, when the ship is in sharp turn on the spot, a forward gear is reversed, the front and back screw propellers required for starting the two sides are all pushed in the opposite direction, so that the balance and stability of the ship body can be kept, the ship can not be overturned, and the ship can quickly turn or turn around 360; if necessary, turn again, and so on. If the ship is asymmetric, the ship body can be overturned or violently shaken, the balance of the ship body can be kept only by transversely pushing under the conditions of front and back reverse pushing and symmetry, and the horsepower can be increased by transversely pushing without violently shaking. The propellers are symmetrical front and back and also symmetrical up and down below the waterline, namely, the propellers on the same side can be started to temporarily keep the balance of the ship body when the ship body is unbalanced; can turn quickly to avoid the attack of the enemy missile and the collision of the submerged reef.

Fourthly, the technical key points are as follows: 1, the front propeller and the rear propeller are necessarily symmetrical in position; 2 the propellers on the two sides do not influence navigation until being stretched; 3, making a sliding cover; 4 each propeller can be driven by a motor independently without a transmission shaft.

Fifthly, accompanying drawing explanation: fig. 1 is a schematic plan view of a bottom bay of a ship, in which fig. 1 is a set of propellers for rapidly turning the ship to the left; 2 is 1 group of propellers for making the ship body turn right rapidly; fig. 2 is a side view of a ship, and 3 in fig. 2 is a water line.

Claims (5)

1. A design scheme of a military ship capable of rapidly turning is characterized in that: 2 groups of telescopic propellers are symmetrically arranged at the two sides and the front and the back of the ship.

2. The fore-aft symmetric propellers of claim 1 grouped front left-aft right, front right-aft left; each propeller independently uses a motor without a transmission shaft; the upper part and the lower part of the waterline are symmetrical; when turning, the ship body is pushed in the opposite directions of the front direction and the rear direction so as to achieve the purpose of quickly turning and keep the balance of the ship body. If the ship is blown transversely by typhoon, the propeller on one side of the ship body can be pushed transversely along the wind to push the ship, so that the ship cannot be overturned; certainly, the ship can be quickly turned to move forwards or backwards to ensure the safety of the ship.

3. The two-sided propeller of claim 1 is retractable to avoid increasing the resistance of the ship to forward travel; after the rotation, the sliding cover is still covered tightly, and the sliding cover needs to slide from the middle to two ends.

4. When the gravity center of the ship body deviates, one propeller is started to temporarily keep the ship body in balance to strive for time to adjust the gravity center in the ship.

5. The rapid turning can avoid the attack of enemy warships or missiles, attack enemy warships and attack enemy warships.
