Abstract

The present invention relates to the technical field of ships, which discloses a warship. The prevent invention is characterized in that the present invention comprises a shell, a power mechanism, pushing mechanisms, a cambered protective wing and a sound isolation layer, wherein the pushing mechanisms are fixed on both sides of the bottom of the shell. The protective wing is connected with the shell into integration, and is provided with a plurality of eyelets with large inner ports and small outer ports. The sound isolation layer is stuck on the inner side of the protective wing. The warship has the characteristics of high running speed, strong maneuvering performance and strong concealment performance, solves the problem that a common warship backwards sinks, and can be widely used in the civil and military aspects.

Description

A kind of submarine

Technical field

The present invention relates to the submarine technology field.

Background technology

Upgrading along with world technology competition and military competition, the effect of military submarine in command of the sea and mastery of the air seems particularly important, but the screw propeller as pushing mechanism of all at present submarines (as the diamond level of Ohio, USA level and France), produce very big noise during rotation, this is disguised for requiring under water, the high submarine of reliability is a fatal defective, promptly as easy as rolling off a log the discovery by the enemy and under attack.

Summary of the invention

The purpose of this invention is to provide the good submarine of strong, the hidden performance of a kind of maneuvering performance.

For achieving the above object, technical scheme of the present invention is: a kind of submarine, it includes housing, actuating unit and is fixed at least one pair of screw propeller on the housing bottom both sides, the outside of screw propeller is fixed with the arcuation flap that is connected as a single entity with described housing, sound isolating layer is posted in the flap inboard, has big, the outer young eyelet of internal orifice on the described flap.

A kind of submarine involved in the present invention, screw propeller is installed in the submarine two bottom sides, and when submarine bent to right, right side screw propeller reversed or shuts down and gets final product; If when turning left, then left side screw propeller reverses or shuts down and gets final product, submarine can be in very little radius or the original place realize turning, be fixed with in the outside of submarine screw propeller that the band internal orifice is big, the flap of collar extension small perforations, and the inside portion is fixed with sound isolating layer, the sound that makes screw propeller send is shielded greatly, and exterior probing wave also easily absorbed greatly, makes the concealment of submarine strengthen greatly.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing, the structure and the principle of a kind of submarine provided by the invention is described in further detail.

Be depicted as a kind of Submarine Structure scheme drawing as Fig. 1 a, Fig. 1 b, constitute by housing 1 and the screw propeller 2 that is fixed in the housing bottom both sides; Screw propeller 2 is at least a pair of (length according to submarine is set).As shown in Figure 2, screw propeller is left and right screw propeller 21,22, is fixed as one with submarine bottom shell base plate 61,62 by anchor fitting 41,42 respectively, as shown in Figure 3, screw propeller 21,22 is fixed as one by the ship abdomen 5 of anchor fitting 41,42 with the submarine bottom.Some screw propeller 21,22 co-rotation can realize that submarine advances fast; When turnon left, the some screw propellers 21 in the left side shut down or reverse, and some screw propeller 22 normal operations in the right can be realized turnon left rapidly in minor radius even original place; When right-hand corner, the some screw propellers 22 in the right shut down or reverse, and some screw propeller 21 normal operations in the left side can be turned right rapidly in minor radius even original place.Thereby reach the purpose of fast reserve, this hides enemy attack and protects oneself particularly important for the various submarines in actual combat.

In addition, in order to improve the submarine concealment performance, shown in Fig. 2,3, the outside of submarine bottom screw propeller 21,22 is fixed with the flap 31,32 that is circular-arc, and be connected as a single entity with housing, on flap 31,32, have eyelet 7, and the internal diameter 71 of eyelet 7 is than external diameter 72 bigger (as shown in Figure 4), thereby make screw propeller 21,22 sound that produced be gone back, to reach hidden purpose by inner hole surface 73 refractions of eyelet 7.Simultaneously, because the existence of eyelet 7 makes the inside and outside current of flap 31,32 can remain unimpeded.And being fixed with the sound absorbing layer 9 (as shown in Figure 4) of one deck such as rubber and so in the inboard of flap 31,32, the sound that makes screw propeller produce is further absorbed.

Claims (1)

1, a kind of submarine, include housing, actuating unit, be fixed at least one pair of screw propeller on the housing bottom both sides, the outside of screw propeller is fixed with the arcuation flap that is connected as a single entity with housing, sound isolating layer is posted in the flap inboard, it is characterized in that: have big, the outer young eyelet of some internal orifices on the described flap.
