Abstract

A kind of submarine drag reduction tip cap, triangle water knockout drum that submarine can be allowed to reduce resistance in navigating by water under water.It is weldering plus triangle water knockout drum before weldering plus-minus resistance tip cap back that cylindroid before submarine shell, and that all leaves in this top at two intake and exhaust eye and lower section enters draining eye.For regulating and controlling the middle loss of weight that depressurizes and emerge in deep water, the common trait of drag reduction tip cap and triangle water knockout drum is that front face area is small, can reduce the resistance of underwater navigation.

Description

Submarine drag reduction tip cap, triangle water knockout drum
Technical field
The present invention relates to the device that resistance can be reduced during a kind of navigation of submarine, can especially allow submarine to subtract in navigating by water under water Few resistance, improve the submarine drag reduction tip cap of the speed of a ship or plane, triangle water knockout drum.
Background technology
Speed is slow when present submarine navigates by water under water, and reason is that have the resistance that front face area is brought greatly at two, first, latent Round end before ship, it is this to submarine outer shaped like not changing, it is desirable to which that speed-raising is also unable to lift, now second, that cylindroid of back The submarine profile of whole world various countries is all a sample, and I thinks that this is probably just all to make circle for the pressure in resistance deep water.
The content of the invention
In order to overcome the resistance that present submarine is brought greatly by front face area big, the speed of a ship or plane is slow, energy consumption is big deficiency, the present invention A kind of submarine drag reduction tip cap, triangle water knockout drum are provided.
The technical solution adopted for the present invention to solve the technical problems is:1st, one is put on the round end of submarine shell to subtract Tip cap is hindered, such front face area is small, and the resistance of navigation can greatly reduce, and drag reduction tip cap is upper and lower with submarine round end weld An eye is respectively stayed, the effect of this upper and lower eye is that water enters in cap from lower eye when submarine diving, and original air is by upper eye in cap Discharge, just without the pressure of water in cap in deep water, the water when the surface water surface in cap discharged by lower eye, and air is from upper eye Into, it is at this moment anhydrous in cap, just do not have gravity yet.2nd, burn-on before submarine back that cylindroid a triangle water knockout drum, it Center top is oblique line edge-shaped, and an intake and exhaust eye is stayed by cylindroid top, and the left and right Ge Liu mono- of lower section enters draining eye, Effect is identical with the eye of drag reduction tip cap, and drag reduction tip cap and triangle water knockout drum are all to play a part of to reduce resistance, as to writing brush It is the same to put on pen container, it is unrelated with Method for Inside Submarine's construction.、
The beneficial effects of the invention are as follows:The resistance that submarine navigates by water under water can be reduced, improves the speed of a ship or plane, reduces energy consumption.、
Brief description of the drawings:
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is embodiments of the invention submarine repacking side view.
Fig. 2 is Fig. 1 top view.
In Fig. 1:1st, submarine shell, 2, cylindroid, 3, triangle water knockout drum, 4, intake and exhaust eye, 5, enter draining eye, 6, drag reduction point Head cap, 7, intake and exhaust eye, 8, enter draining eye.
In Fig. 2,1, submarine shell, 2, cylindroid, 3, triangle water knockout drum, 4,5, left and right enter draining eye, 6, intake and exhaust eye, 7, Drag reduction tip cap, 8, intake and exhaust eye.
Accompanying drawing schematic illustration:
It is added in the drag reduction tip cap of submarine shell front.Common trait with triangle water knockout drum is that front face area is small, can be subtracted Few resistance.The effect for the eye that two devices are stayed is depressurized in deep water.Loss of weight when emerging.4,5 position when seeing figure in Fig. 2 It is 5 in Fig. 1.6 be 4 in Fig. 1,3 in two figures all referring to the oblique line edge-shaped to triangle water knockout drum at, 8 be 7,8. in Fig. 1
Embodiment:
In the embodiment shown in fig. 1, drag reduction tip cap 6, be welded at submarine before shell round end, one is stayed above weld Individual intake and exhaust eye 7, lower section stay one to enter draining eye 8, triangle water knockout drum be welded on submarine back that with cylinder 2 before, weld Top stay an intake and exhaust eye 4, lower section left and right Ge Liu mono- enters draining eye (4,5 in Fig. 2).

Claims (3)

1. a kind of drag reduction tip cap, triangle water knockout drum before submarine shell and before cylindroid drag reduction tip cap, triangle water knockout drum it is suitable Sequence connects, it is characterized in that:Drag reduction tip cap before submarine shell round end with being connected, and triangle water knockout drum before the cylindroid of submarine back with connecting Connect.
2. submarine according to claim 1 subtracts a group tip cap, triangle water knockout drum, it is characterized in that:Drag reduction tip cap front is Pointed, the top of triangle water knockout drum is oblique line edge-shaped.
