Technical Field

The invention relates to a method for reducing resistance and quickly dissipating heat of a moving body in fluid, in particular to a method for reducing resistance borne by the moving body in fluid and quickly dissipating heat of the moving body in fluid.

Background

When a moving body in the fluid moves, particularly moves at a high speed, the resistance of the fluid to the moving body is very large, so that the speed is limited, the energy consumption is high, and the voyage is shortened; due to the frictional heat generation, the front end of the moving body is heated sharply, and the front end of the moving body is melted or sublimated or even disintegrated when being heavy, and the performance of the material is obviously reduced when being light.

The current method for overcoming air resistance is to adopt a high-power engine, and the speed of a moving body reaches dozens of times of sound velocity, such as hypersonic missile; the current method for overcoming the water resistance is to use a high-power engine and to use a 'cavitation' technology, and the speed of the 'storm' torpedo reaches 100m/s (about 200 knots); the current approach to overcome the rapid temperature rise is to develop high temperature resistant materials, which have been developed to have unchanged performance at high temperatures of more than 3 thousand degrees celsius.

The above methods all have disadvantages. The high-power engine and the cavitation generator have high energy consumption, and the range of the moving body is limited; the production process of the high-temperature resistant material is complex, and the manufacturing cost is very high.

Except for the above method, can not reduce the energy consumption, increase the range and speed by reducing the resistance of the moving body? Can the exercise body not adopt a new structure to rapidly cool the exercise body, so as to reduce the temperature resistance requirement on the material and reduce the manufacturing cost?

In order to rapidly change the China from the large manufacturing country to the strong manufacturing country and greatly improve the military strength of China, science and technology workers need to make a new way for the technology.

Disclosure of Invention

The technical problem to be solved by the invention is to provide a method for reducing resistance and quickly dissipating heat of a moving body in fluid, so that the resistance of the moving body in the fluid is reduced, and the moving body in the fluid can be quickly dissipated.

In order to solve the technical problems, the technical scheme of the invention is as follows:

a drag reduction and rapid heat dissipation method for a moving body in fluid comprises the moving body; the moving body comprises all objects moving in the air or in the water, such as missiles, airplane bodies, shells, high-speed rail locomotives, torpedoes, submarines, ships and the like.

The front end of the moving body is a front end part; the front end portion either originally existing or newly installed; the front end portion may be a hemispherical shape with its apex right in front, a streamline shape, or other shapes.

The front end has inside one V-shaped guide pipe and several bent guide pipes, and the V-shaped guide pipe and the bent guide pipes have their axes in the same horizontal plane.

The cross section of the herringbone flow guide pipe or the bent flow guide pipe is round, flat or in other shapes.

The front port of the herringbone flow guide pipe or the bent flow guide pipe is positioned on the front end surface of the front end part and is opened forwards; the rear port of the herringbone flow guide pipe or the bent flow guide pipe is opened to the side rear of the front end part.

The center point of the front port of the herringbone flow guide pipe is positioned at the peak of the front end part.

The plurality of bent draft tubes are arranged on two sides of the herringbone draft tube, and the bent draft tubes on the two sides are axially symmetrical with each other.

There are both attractive and repulsive forces between the molecules, which are balanced when the distance between the molecules is equal to r. When the distance between molecules is less than r, both the attractive force and the repulsive force increase as the distance decreases, but the repulsive force increases significantly faster than the attractive force, so that the repulsive force is greater than the attractive force, and thus the molecular force (the resultant force of the attractive force and the repulsive force) appears as the repulsive force. When the moving body in the air moves forwards at a high speed, the air in front of the front end part of the moving body is compressed, so that the distance between air molecules is smaller than r, and the moving body collides with an air wall under the action of strong molecular force, so that the resistance is large. And because the specific heat capacity of air is small, the temperature of the front end part is increased quickly due to frictional heat generation. After adopting such structure, this application provides the passageway that flows backward for the air in locomotorium front end portion the place ahead because chevron shape honeycomb duct and a plurality of crooked honeycomb duct, and the density of locomotorium front end portion place ahead air reduces, that is to say the distance between the molecule increases, and the air is to the resistance of locomotorium front end portion reduction, and the frictional heating is less. On the other hand, in the process that the air flows through the herringbone flow guide pipe and the plurality of bent flow guide pipes at the front end part, the interior of the front end part is continuously cooled, so that the dynamic balance temperature of the front end part is low, and the air can be used even if a material with low temperature resistance is adopted. The reduction of the resistance of the moving body in water can be explained just by the fact that the herringbone flow guide pipe and the plurality of bent flow guide pipes mainly play a role in reducing the resistance due to the large specific heat capacity of water, and the heat dissipation and temperature reduction also exist but do not play a great role.

After the structure is adopted, because the resistance borne by the front end part of the moving body is reduced, the range and the speed of the moving body are greatly increased under the condition of an engine with the same power according to the law of conservation of energy.

After adopting such structure, because the internal surface and the inside of the front end of the moving body are all radiated, the radiation is fast, the temperature-resistant requirement on the front end material is reduced, thereby the manufacturing cost is obviously reduced.

By adopting the structure, the structure probably plays a role in improving the manufacturing and military force of China.

After adopting such structure, a new way is opened for drag reduction and heat dissipation.
