Last week, the foreign media said China's ongoing discovery of electromagnetic catapult experimental satellite photos, similar technology is one of America's newest aircraft carrier "Ford" class core technology. Recently, the Chinese Academy of Engineering, Naval University of Engineering, Professor Ma Weiming during National Science and Technology Progress Award acceptance speech was forwarded many netizens. During this speech, Mayuan Shi said China electromagnetic catapult technology research has been successful. The speech also revealed about our all-electric ship propulsion systems, etc. The same study chaired by 马院士 major military technology research projects progress.
a Weiming Chinese Academy of Engineering academician who is the youngest academician, he was born in 1960, is committed to an independent power generation and supply systems research. Create and develop the basic theory of second-phase generator system power supply system, capturing system stability prediction, natural oscillation suppression, complex fault diagnosis, domestic and international long-term and short circuit protection key unresolved technical problems (in Germany the company to purchase its stable device patent), developed a twelve-phase rectifier power generator system with the international advanced level, has been equipped with applications for the 2000 National Science and Technology Progress Award (first place). Proposed a three-phase / phase double-winding power integrated twelve new principle, under which developed the boat with AC and DC power generation and supply systems. Conducted an independent power system electromagnetic interference suppression technology forecasting theory and breakthrough completed vehicles of different power system electromagnetic compatibility research. The above results of both theoretical innovation and development, and the key technology to solve engineering problems, and has been applied, has made significant achievements. Also won the national invention prize two, three military and technological progress award, second prize four national patents 4. Published two monographs, professional level international journals published 61 papers, wrote 36 research reports. Presided over the completion of doctoral and post-doctoral programs, the research group led by the National Natural Science Foundation of "innovative research groups" funding. PhD, MA 50. Abandon the appointment of foreign-paid, third-degree executive positions declined to devote himself to research and teaching first line of defense and make an important contribution to the academic development.
n this published in 2011 acceptance speech, there is a text referred to "a cutting-edge technology", calling it "represents the future new main battle ship iconic core technology", published in this article is not as fashionable Reading this text is mentioned exactly what. Now combined with many other information can be found PROCEEDINGS academicians saying this is China's aircraft carrier electromagnetic catapult technology. The paper said the device's first prototype was made in 2008, followed by a full-size prototype made 1:1, "breaking all the key technologies to achieve the world's most advanced technology with the simultaneous development." U.S. aircraft carrier electromagnetic catapults ground experimental facilities in 2010 successfully stereotypes. This means that the Chinese aircraft carrier catapult electromagnetic type testing was completed at the same time, and may have been successful catapult testing.
This information can be had published in the "Liberation Army Daily" in an article in the Academy of Sciences in recognition of Walter Ma part to get cross-validation, the article said: "In the forefront of research on high ground, as long as Ma Weiming spotted subject, even though no one throw a penny, he will bite the bullet and forge ahead their own money. 5 years ago, he aimed at an international science and technology in the field of cutting-edge technology, apply to one million yuan demonstration funds, but after the completion of feasibility reports, no one was Give him the money voted reason is simple: the country hundreds of millions of special research funding has been allocated to the counterpart research institutions PROCEEDINGS stubborn fresh full: '! Zaguomaitie too dry' He took 20 million from their accumulated scientific research million, led by a gang of young experts laboratory work hard for two years, successfully developed a small prototype. "
Foreign media had previously reported that among Chinese Navy aircraft carrier catapult his early years to carry out research, was based on the old aircraft carrier catapult Old 80s purchased from Australia on the basic principles to find out the structure of the steam catapult, and conduct further research, developed with the hope that the U.S. Navy C-13 steam catapult similar large-scale steam catapults for our carriers. After the test found that there are some problems on the structure of China's self-developed steam catapult, it is difficult to meet the requirements of carrier-based aircraft catapult a variety of models. Steam catapult technology is extremely complex, rely on the Navy itself is difficult to complete an independent research institutes for further improvements.
In addition, Ma Weiming Academy acceptance speech also mentioned the development situation of China's AIP submarine power systems, the equipment in the world is originality technology. Before this technology appears, because the system does not rely on a small aerodynamic total power, it is difficult to satisfy simultaneously driven submarine navigation, electronic systems and charging needs, and therefore the world, including Germany, Sweden (Japan's "black dragon" class submarines Sweden technology) AIP submarines developed countries are only 1-2 knots underwater slowly "crawl", compared with the traditional conventional submarines is only increased the latency time underwater. And Ma Weiming Academy presided over the development of new power generation, substation system in one fell swoop to change this situation, our 039B type (Western called "meta" level) AIP submarine after using this technology can meet the underwater navigation and low battery charge and is based powered submarine electronic systems need thus truly need conventional submarines underwater combat long voyage, like a ship "small submarine." Russia and China last year reached an agreement with China to jointly develop "Amur" class submarines AIP model.
Ma Weiming ship Academician acceptance speech mentioned integrated electric propulsion system is also one of China's recent naval field to catch the world's highest levels of research. Walter Ma said in his speech: "ship integrated power system is the third revolution will ship power platforms daily supply, electric propulsion and power supply of the three weapons of modern high-energy one, due to the cancellation of the traditional mechanical propulsion. device, from the source to reduce the difficulty of solving the problem of acoustic stealth, while creating the conditions for a new concept of electromagnetic rail guns, laser guns and other weapons on the ship. "According to foreign media reports, the new generation of multipurpose frigates will be China's first use of type 054B This advanced technology, which will be a major task of anti-submarine warfare ships bear.
