Beijing Science and Technology University Professor Wang Haifu, twenty years of silly do not change the strong military dream. In the 2016 National Science and Technology Award Conference, 66 results were awarded the National Technology Invention Award project, including one called "active damage element technology" project won the second prize. In this paper, "active damage element technology" is a new type of warhead material technology.
Military observers said observers, from a similar point of view abroad, this should be a substantial increase in missile warhead damage ability of the new technology, i
n theory, can make the missile damage the radius of the aircraft doubled. However, other countries in the world, including the United States initially proposed similar ideas, have not yet made the actual development results.
The US Navy had proposed in 2002, similar to the idea of explosion damage element, known as 100% increase in missile damage radius, but this project does not seem to be below, it seems that the United States is responsible for "thinking", China is responsible for "dry"
Beijing Institute of Technology Professor Wang Haifu and his team
"China Science" reporter interviewed the original as follows:
Breakthrough two major technical problems
Wang Haifu in 1985 to enter the Beijing Institute of Technology, in 1996 after a doctorate in school. Thirty years, he has been in the "defense technology and weapons and equipment" to deal with.
According to reports, there are three main weapons technical performance indicators, namely, range, accuracy and power. Wang Haifu to solve the problem is the power: "It's like playing football, no matter how good the backcourt, to the front are Rimen kick, if you do not play, that is not."
But a substantial increase in the power of weapons is recognized as the world's major bottleneck problems. Wang Haifu hosted the project is aimed at the technical problems.
"We have invented a new type of explosive material damage element, both with the mechanical strength of similar metals, but also contains high energy explosives and chemical energy, but also with the inert material similar to the safety, can be directly machined, only high-speed target Wang Haifu said, before the inert metal damage element can only be pure kinetic energy damage target, and this new material damage element with the kinetic energy of perforation and explosion of double damage ability, power will be multiplied to enhance.
For the technical level and status of the research results, Wang Haifu admits: "the past two decades, if the development and development of China's armed equipment as a track from a comprehensive catch-up to the part and run even a limited lead process, The results of technological invention undoubtedly belong to and run or lead.
From whimsy to technological innovation
However, few people know that the defense scientific and technological achievements with complete independent intellectual property rights, from the concept of the technology to the breakthrough of key technologies, the breakthrough of the national defense science and technology innovation, To the arms and arms in the arms of the platform to promote the use of pooled Wang Haifu and his research team of nearly two decades of effort.
In 1996, Wang Haifu received a doctoral degree from Beijing Institute of Technology, began to explore efficient damage technology, innovative ideas and new ways. He keenly insight into the active damage element and its ammunition warhead technology innovation research. However, this technical concept was not recognized by the mainstream academia, many projects have failed to apply for the end. However, has been "looking for a good research direction," Wang Haifu is not discouraged.
Finally, hard work pays off. In 2003, Wang Haifu for the first time won a national defense field fund project research project support. Although the funding is only more than ten million, but the initial study for technical concepts and feasibility of the initial verification provides a key support. In 2006, Wang Haifu on this basis, access to a forefront of innovative weapons and equipment plan for the full support of the study into the full access to technological innovation and key technology research possible.
As the 2006 Beijing University of Science and Technology was the only approved the forefront of the weapons and equipment innovation project leader, Wang Haifu a good grasp of this opportunity. As a result of technological innovation is significant, a major breakthrough in key technologies, especially military significance, in 2009 the research work was approved to transfer to the forefront of innovative application research, further breakthroughs in weaponization application of key technologies, and finally won the 2016 National Technology Invention Award second prize.
Do not forget the beginning of the heart, sharpen the edge for the country blade
From the creation of innovative ideas to the validation and application of technology to the achievement of technological achievements, Wang Haifu's research road is not smooth sailing, and can stick for 20 years down in his own words: "As a defense science and technology workers, So that research results in the application of weapons and equipment research and development, especially for the development of national defense science and technology have an important role in promoting the increase in national defense a bit hardness, is both a professional pursuit, it is a great comfort.
Just enter the Beijing Institute of Technology, Wang Haifu do not understand the fire and pyrotechnics professional in the end what is, but in the future study and research, he gradually recognized the weapons disciplines and the importance of technology to the country and began to adhere to it , A blink of an eye is thirty years.
It is because of this heart, in the face of difficulties and failures, Wang Haifu to calmly face, more painstaking research and technological innovation, "because any program, theory, technology and even experience, only through scientific experiments can be fully verified, Answer the question of the most effective and most direct way.

"Beech" missile fragments, relying on kinetic energy penetrating anti-target, Russia show this map is to show that its anti-aircraft missile fragmentation style hit the aircraft and the missile hit the MAS different
Military commentators believe that the article mentioned the new explosive material damage element, if it can be applied to air defense missiles or air-to-air missiles, replace the original prefabricated fragments of destruction, will be able to significantly improve the missile's damage capability. According to the original description, this type of material with kinetic energy perforation and explosion double damage mechanism, high-speed target hit the explosion, the explosion principle should come from the material and hard objects, high-speed impact energy. To play a new type of fragment maximum lethality, it is best to target external structural strength is weak, easy to be penetrated, there are structural strength within the target, after being hit can be detonated damage components, resulting in greater damage - in other words In other words, the goal is to "soft outside the hard", while the aircraft is the most complex description of the goal.
In order to investigate the 9M314 "Beech" missile damage test conducted by the MAS aircraft, it can be seen that the ordinary prefabricated fragments only rely on kinetic energy to damage the effect. If the fragments can be exploded inside the aircraft, the effect is drunk. Of course, the goal can not be civil aircraft
Modern aircraft are usually covered with external skin, the internal framework of high-strength support. If the missile warhead fragment after flying through the skin, impact to the aircraft interior skeleton or engine and other hard parts and then a second explosion, that for the aircraft, this damage is fatal, the effect far more than to the aircraft left One hole.
Air defense missile warhead improved through prefabricated fragments, greatly enhance the damage capacity is a precedent. It is reported that China's large exports of "flying crossbow" -6 portable air defense missiles, although the Warhead is only 1 kg of weight, but because of its prefabricated fragments made of special titanium alloy, hit the target is still more than 300 degrees high temperature, Detonate the fuel tank. It is reported that, according to the Russian reaction in Syria to participate in actual combat, FN-6 missile anti-combat effectiveness but more than the warhead of the United States and Russia more similar missiles. If the destruction of the pieces to the invention of the new explosive fragments, a new generation of air defense missiles will have a greater power increase.
Gulf War, conventional missiles were SA-7 hit the US A-10 aircraft, we can see that the power of this shoulder-fired missiles
But we have already achived this type of design as shown in above post and its cutting edge. China has done it now, we perfected it years ago.
