Abstract
A torpedo shell speedup bag is composed of a bag cover, a bag bottom and water flow grooves together. The bag cover is arranged on the outer surface of a torpedo shell and is of an arc shape. The arc-shaped bottom of the bag cover faces the head portion direction of a torpedo. The inside of the bag cover is provided with the bag bottom. The water flow grooves connected with the bag cover extend towards the tail portion of the torpedo from under the bag cover. The shell of the same torpedo can be provided with the speedup bags covering the whole shell surface. The same circle line of the torpedo shell is supposed to be at least provided with two speedup bags which are arranged symmetrically with the axis of the torpedo as the axis. The torpedo shell speedup bag enables an original viscosity relationship between the torpedo shell and the water to be changed into a sliding relationship when the torpedo proceeds in water. Therefore, the procession speed of the torpedo can be greatly improved definitely, and accordingly the energy efficiency and the hitting force of the torpedo are improved.
Description
Technical field
The present invention relates to the design of torpedo shell shape, relate in particular to torpedo shell speedup bag.
Technical background
Existing torpedo shell outer surface all is smooth.When torpedo was advanced in water, the housing of smooth outer surface certainty and water generates friction made torpedo shell outer surface and water form viscous force, also just increased resistance, increase energy consumption, have affected the torpedo pace.
Summary of the invention
The objective of the invention is to provide a kind of when torpedo is advanced in water and the viscous relation of water become sliding relation, and make described viscous force become the torpedo shell of the motive force of torpedo.This torpedo shell is exactly at existing torpedo shell the speedup bag to be installed.
Described speedup bag by bag at the bottom of, pkt. flap and water flow grooves consist of jointly.Described pkt. flap is arranged on the outer surface of described torpedo shell, and is arc.The end of described arc, is towards the cephalad direction of described torpedo.
Below described pkt. flap interior, be provided with the described bag end.The water flow grooves that is connected with the described bag end was extended to described torpedo caudal directions from the described bag end; The transversal of the groove face of described water flow grooves is recessed camber line in the described torpedo.The groove width of described groove narrowed down, shoals until mild the disappearance by wide gradually from the described bag end to torpedo tail end direction.
When arranging described speedup bag, should the symmetry take the axis of described torpedo as axis install same torpedo shell; The described speedup bag that arranges at the same loop wire of same torpedo shell should be no less than two, and is the symmetry setting.
Carry out intensive when described speedup bag is set at the whole housing of same torpedo, should keep installation position globality on the layout on the described torpedo shell of each described bag symmetrical.
Be provided with the torpedo-launching of torpedo shell speedup bag of the present invention when shell after, the current that water forms form the resistance current to the torpedo in advancing at a high speed.When the resistance current arrived the described speedup bag sack line be located on the torpedo shell, the resistance current were because of at the bottom of the support that loses suddenly housing pours into bag, and formation has also just formed the thrust to torpedo to the impact at the bottom of the bag.Described current namely wash away to the torpedo afterbody after the bounce-back at the bottom of the bag, have formed again the again thrust to torpedo, and therefore, described speedup bag also just can form thrust twice to torpedo.
The invention has the beneficial effects as follows: when the torpedo that is abound with the speedup bag on the whole housing is advanced fast, just only can form sliding relation rather than viscous relation with water in water, thereby increase considerably the gait of march of torpedo, improve the hitting power of torpedo.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail.
Fig. 1 is the torpedo shell front view that torpedo shell speedup bag of the present invention is installed.
Fig. 2 is that (analysing and observe) figure is looked on Fig. 1 left side.
Fig. 3 is Fig. 2 A--A cutaway view.
Fig. 4 is the schematic layout pattern that intensive is installed described torpedo shell speedup bag on the torpedo shell.
Among the figure: 1, case head, 2, the speedup bag, 3, the sack line, 4, water flow grooves, 5, the groove tail, 6, body, 7, pkt. flap, 8, the bag end.
See Fig. 1, Fig. 2, Fig. 3, Fig. 4, the torpedo shell is made of jointly torpedo case head 1 and the torpedo shell body 6 that is provided with speedup bag 2.See Fig. 1, when torpedo is advanced in water fast, current and the rear current that form fine dotted line arrow signal among the figure of torpedo case head 1 conflict by the signal of heavy line arrow flow through along body 6, after these current are flowed through pkt. flap 7, arrival sack line 3, current because of lose support to pour into bag at the bottom of 8, current have also just formed thrust one time to torpedo.Current flow through that groove tail 5 is rear to be washed away to the torpedo tail end arriving a bag end 8 chute 4 that rebounds after being obstructed downstream, have formed thrust to torpedo with regard to another, therefore, and because the effect of speedup bag just makes torpedo obtain extra-push model twice.
If be covered with described speedup bag at torpedo shell, the torpedo when advancing in water and the relation of water body will become sliding relation by the viscous friction relation, also just can increase substantially the gait of march of torpedo, improve the hitting power of torpedo.
See Fig. 4, if be covered with described speedup bag at torpedo shell, its installation position should be the bag setting of staggering of adjacent rows, so just can more arrangement speedup bags and the effect of more effective performance speedup bag.
