Israel develops high-performance nanoscale electronic fibers

According to Voice of China's "News Evening Peak" report, a small dandelion, gently blowing, white fluff like an umbrella flying in the wind, falling to the Quartet ... Now, Israel uses nanotechnology to create a Dandelion-like electronic fibers, which only have 1/2000th of the diameter of hair, can effectively intercept radar-guided **.

It's hard to imagine. So how does this subtle electronic fiber "confuse" the airspace? What new thinking does it bring to the development of weapons in the future? Please listen to today’s observer Li Li, a professor at the National Defense University, for an in-depth analysis.

According to reports, prior to this, the Israeli Air Force used a fiber glass called “husk” to interfere with enemy radar, but the fiberglass was relatively “dandelion” heavy, and the enemy could judge “some bright spots on the radar” according to its flying and falling speed. Not an airplane." Li Li believes that "Dandelion" succeeded in replacing "the husk", resulting from the progress of chaff material.

Li Li: At present, underground space is the main ** of all combat aircraft. In order to ensure the safety of war itself, including the safety of fighter planes, fighter aircraft must be equipped with self-defense interference systems. Israel's dandelion electronic fiber, in fact, essentially It is still a kind of chaff material. It should be said that since the Fourth Sino-Japanese War naval warfare, the chaff material only began to be widely used. The early chaff is generally a pure metal material, and its production efficiency is low and its cost is high. . Later, countries began to develop metal-coated glass fibers one after another. In fact, the main thing is to coat the glass fibers with aluminum. The strength and toughness of the glass fibers are increased. It can be pulled very thinly, and it is very thin and even. Good flexibility.

In addition to Israel, the United States and Russia are in a leading position in this field, and they have the largest amount of applications in combat. Now the demand for chaff material has been further improved, that is, the original aluminized glass fiber itself is still relatively heavy from weight. , And once dispersed in the air, it quickly falls and falls off from the plane itself. In this way, when the standard of space, especially radar-guided air space, will effectively identify which aircraft it may be. Which may be your bait, obviously it still does not cause a very important protection to the aircraft itself. And this time, Israel’s electronic fiber of its dandelion is 130 nanometers in diameter. We know that a hair has a diameter of about 50,000 nanometers. Your electronic fiber is about 1/2000 of the diameter of this hair, so it is safe from protecting its own fighter aircraft. From an angle, it is clear that dandelion electronic fiber is now more technical.

It is understood that each aircraft can carry millions of such “dandelion” electronic fibers, which are 100 times harder than diamonds and can be completely hidden and suspended in the air. Li Li believes that it can weave an invisible huge electronic network and is a new development in electronic countermeasures.

Li Li: My basic principle of action of this dandelion is that once a fighter plane is attacked by a fighter, on the one hand we know that the onboard electronic interference equipment, including the onboard alarm equipment, will start. In this case, Under the fighter plane, on the one hand, it evades its existing flight trajectory. In addition, it will release the interference foil, and once released, the air will be disturbed during the course of the attack. So the most fundamental principle of dandelion is a new development of electronic countermeasures. It is an electronic fiber that is 100 times harder than diamonds. It can be completely invisible and suspended in the air. Once released, for a long time, this area is enveloped by an invisible electronic giant net. , and such a giant network will form an effective interference to the radar-guided **, so that there is no way to identify the **, whether it is the bait or the aircraft itself, and if so, the security of the fighter itself will be Protection, so from this perspective, this is a new means of fighter intervention.

So, what kind of influence does this “dandelion” electronic fiber bring to the development of future weapons? Li Li believes that electronic counter-offensives will become the focus of competition in various countries in the future.

Li Li: Now that various new technologies are indeed used very quickly in warfare, the future electronic warfare must be full-spectrum and multi-mechanism. For example, after this type of dandelion is used as an electronic fiber, it may be present on the one hand. Radar-guided ground-air turbulence interferes, so if infrared-guided ** can not form interference, then obviously the fighter is still unsafe, so it is necessary to require such a network, and for infrared-guided ** A certain amount of interference, therefore, in terms of the requirements of this technology, I think it will put forward higher requirements for the future development of the foil material, that is to say, the new type of chaff material must be maintained on the one hand. On this basis, we must also develop multi-functional and complex development, and we must also develop in the direction of multi-band anti-jamming. Therefore, with the research and application of these new materials, its scope of interference, including integrated combat effectiveness, will be further improved. Therefore, it can be predicted that chaff disturbances will continue to be the first kind of soft killing method against various kinds of guided weapons. .
