Technology for reducing resistance of water to sailing ship

Abstract

In order to reduce frictional resistance of water to a ship, a large number of air holes are distributed in the surface, making contact with a water body, of a hull, a high-flow air compressor is used for supplying air to make a large number of air bubbles be generated in the air holes, as a result, contact between the water and the hull turns into contact between the hull and the air, and therefore the frictional resistance of the water to the hull is greatly reduced.

Description

A kind of technology of water to the resistance of navigating that reduce
Technical field: reduce water to the resistance of navigating.
Background technology: for reducing water to the resistance of navigating, be mainly to make hull surface smooth to reduce the friction force of water at present.The principle of the invention is completely different, and the effect of minimizing water body friction force is more outstanding.
Accompanying drawing explanation: Fig. 1 is that the immersion part of ship is with the schematic diagram of air cover 2.
Fig. 2 is the salient point of air cover and the partial enlarged drawing of fumarole.Summary of the invention: ship is subject to the resistance that resistance is mainly water in motion.If the surface contacting with water at hull is covered with a large amount of pores, by air compressor, to pore air feed, make to produce a large amount of bubbles, in motion, hull has become contacting of hull and air filled cavity to ship with contacting of water.If bubble is abundant, be air with most contact of hull.Density of air is lower than water, and the ship in travelling is subject to the friction drag of air more much lower than the friction drag contacting with water.Like this can greatly reduce the resistance of shipping agency in entering, greatly improve shipping agency speed.Concrete enforcement technology: concrete enforcement is that as the air cover 2 that rubber, plastics etc. are made, air cover 2 is connected with air compressor 3 by air inlet duct at the surface of hull immersion cover last layer resistant material.Air cover inwall is distributed with some microscopic bumps 4, and the top of salient point 4 is close on hull, the fumarole 6 that forms some air-jet channels 5 and communicate with air-jet channel between salient point and salient point.Air compressor is to the inflation of air cover, and fumarole can produce a large amount of bubbles.
