Description

Eco-friendly chevron dipoles and chev cartridges loaded with chevrons

The present invention relates to an environmentally friendly chief dipole and a chaff manufactured by using the same, and a chaff cartridge to which the chief is loaded. More specifically, the environmentally friendly chief dipole comprising a basal fibrous chief dipole and a chafe and chief manufactured using the same It relates to a chap cartridge to be loaded.

The most common method used by planes to avoid radar tracking is to spray metal thin films into the air. The metal thin film pieces are generally made of a metal thin film or a fiber coated with a metal thin film to form an electromagnetic dipole in electromagnetic waves.

The thin metal pieces produce clouds of fine dipoles when sprayed into the air on an airplane, and these dipole clouds act as a passive reflective antenna, sending a strong reflection signal to the tracking radar, thereby producing a tracking radar signal. It confuses and prevents real objects such as airplanes from being tracked by radar.

These radar obstruction metal thin films have historically been used in some countries under the name Window or Duppel, but now the name Chaff is commonly used in the United States. Currently, most fighter aircraft and tactical helicopters are equipped with self-protecting chevron spraying systems, and even passenger jets are increasing in number, and warships are becoming more common as obstacles to anti-ship fleet missiles. .

On the other hand, these chevron dipoles are made of silver coated nylon, aluminum flakes and aluminum coated glass fibers.

However, in the case of the above-described chief dipoles such as silver coated nylon, the price is expensive, and it is difficult to manufacture fine fibers having a diameter of about 90 μm or less, and the aluminum flakes are somewhat denser than the silver coated nylon, When a large number of dipoles cannot be embedded in a cartridge and are dispersed in the manufacturing process or in the air, they tend to be twisted and deteriorate in efficiency as a chef.

In addition, the glass fibers coated with aluminum can no longer raise the temperature of the molten aluminum to be coated due to the low heat resistance of the glass fibers during manufacture, resulting in the high viscosity of the molten aluminum and the flowability of the reduced melt surface of the coated glass fibers. As the non-uniformly produced, when dispersed in the air, there is a disadvantage that it is not tangled with each other evenly distributed.

That is, in order to coat the glass fibers with aluminum as the most economical method, the spun glass fibers should be contacted at a temperature of about 660 ° C. or more, which is the melting point of aluminum, but the heat resistance temperature of the glass fibers is about 460 ° C., in particular, the vitrification temperature. The surface of the glass fiber may not be coated uniformly and slippery because it is so low that it should be cooled to about 600 ° C. in order to maintain the physical properties of the glass fiber and to coat the aluminum with instantaneous contact with the aluminum melt in a very short time. In addition, there are disadvantages of reducing the radar cross-sectional area due to the small protrusions of aluminum appearing on the surface of the coating due to entanglement and sticking to each other during air spraying.

Furthermore, boron oxide and fluorite compounds, which are introduced for the purpose of lowering the melting temperature, improving the flowability of the melt and defoaming the glass fiber, not only adversely affect the eyes, skin and respiratory organs, but also emit fluorine gas. As a result, there is a problem that pollutes the human body and the environment.

On the other hand, the above-mentioned chevrons are made of a kind such as silver coated nylon, aluminum flakes and aluminum coated glass fiber, etc. The chopped chaps are cut to a specific length, and each cut chopped into a bundle of dense fibers. Although it is generally used in a manner in which a plurality of fastened and spreadable airs, such as about 20 cm in a tube or cartridge, are stacked and sprayed and dispersed in air, When loaded into tubes or cartridges for sparging and dispersal in the air, they are each loaded with the same length and nearly the same density, so that they tend to disperse well when sparged in the air.

Therefore, due to the high heat-resistant fiber, the surface can be uniformly and smoothly coated, and even a small diameter fiber can be easily coated with a metal thin film to fasten a large number of chevron dipoles so that they can be widely applied without being stuck or entangled with each other during airspraying. In addition to being able to be distributed, this maximizes the laser cross-sectional area, makes it possible to manufacture without contaminating the human body and the environment, and is also environmentally friendly to secure various wavelengths of the tracking radar when spraying the chevrons into the air. Chef is required.

On the other hand, hereinafter, the principle of the chief drop speed according to the specific gravity of the fiber type will be briefly described.

When the chaff is sprayed into the air, the terminal velocity of each dipole free fall is generally determined by temperature, air density, air viscosity, dipole density, dipole diameter, and dipole fiber orientation when falling. do.

In addition, when the object falls freely from the air to the ground, the dependence is expressed as V _T = (mg / k) ^1/2 . Thus, the drop dependency of the chief dipole having the same diameter and length is the square root of the specific gravity of the chief dipole. Will be proportional to.

Therefore, as in the third to sixth embodiments of the present invention, when the chafe dipoles made of different fiber types are each formed with the same diameter, length and thickness, the specific gravity of each chap dipole is different.

For example, if silica fibers, glass fibers, and basalt fibers of 20 μm diameter are coated with aluminum having a thickness of 2.5 μm to form a chafe dipole of 25 μm in diameter, the specific gravity of the dipoles is 2.34, 2.61 and 2.76, respectively. 20 cm / s, 21.2 cm / s, and 21.8 cm / s, respectively, when spraying in the air, each chafe dipole will disperse and fall at different drop rates, reducing the likelihood of this type of chappoles sticking or tangling together. In addition, since it is sprayed evenly in the air, the function of the chaff can be improved than before.
