On this day 65 years ago, on April 6, 1960 (March 11, 1960 lunar calendar), Ma Weiming, the father of Chinese electromagnetism, was born. Ma Weiming (born April 6, 1960), male, academician of the Chinese Academy of Engineering, power and electrical engineering expert, Yangzhong, Zhenjiang City, Jiangsu Province. He graduated from Yangzhong County Middle School (now Yangzhong High School in Jiangsu Province) in 1978, and graduated from Tsinghua University in 1996 with a doctorate. He is currently the director of the Institute of Power Electronics Technology, School of Electrical Engineering, Naval University of Engineering, and the vice chairman of the 9th National Committee of the China Association for Science and Technology. Ma Weiming, academician, is known as the father of China's electromagnetic catapult. Ma Weiming said that China's strength in research on cutting-edge electromagnetic equipment for ships "definitely exceeds that of the United States". Ma Weiming, the father of Chinese electromagnetism, "The United States is currently a medium-voltage exchange, and it is still at the level of the first generation, missing our generation. (They are currently) only starting to do pre-research medium-voltage DC, and it will be more than ten years later to catch up with us. (A technology) is not leading, advanced or not advanced is not what you say yourself, it needs to be evaluated by the world's peers, and the standard exists objectively." "It took us 1/5 of the time to complete the electromagnetic blocking. Is it difficult to block with electromagnetic ejection technology? Ejection and blocking are a positive and a negative. If you solve the positive, won't it be easy to solve the negative?" These two sentences are the original words of Academician Ma Weiming in an interview. Full of confidence, China has decided to equip the third aircraft carrier with mature and reliable electromagnetic catapult and electromagnetic blocking equipment, overtaking the United States! China's electromagnetic catapult test field does not practice fake handles. Recently, CCTV science and technology channel exposed the real progress of China's electromagnetic catapult and electromagnetic blocking technology for the first time, which makes people excited. The electromagnetic catapult system on the road in our country has completed the ejection take-off and electromagnetic blocking landing of carrier-based aircraft. The system is highly mature, stable and reliable, and can be fully boarded. Electromagnetic catapult Why is electromagnetic catapult so good? Compared with the old-fashioned steam catapult, electromagnetic catapult has the following advantages: Improve dispatch efficiency: Electromagnetic catapult preparation time is short, and the operation efficiency is high, which can greatly improve the dispatching rate of carrier-based aircraft. Wider range of use: Whether it is a carrier-based fighter jet, a small drone, or a large early warning aircraft, the electromagnetic catapult can be ejected. Improved stability: The average period between two major failures of the steam catapult currently in use is 405 weeks, while the electromagnetic catapult can reach 1300 weeks. Improved energy utilization and reduced cost of use: The efficiency of the electromagnetic catapult is greatly improved compared to the steam catapult, and the cost of use is greatly reduced. Reduced requirements for on-board auxiliary systems: The steam catapult relies on a large number of auxiliary systems provided by the aircraft carrier, while the electromagnetic catapult is much simplified. Although the USS Ford nuclear-powered aircraft carrier has been equipped with electromagnetic catapult, there are many problems. I believe that in terms of electromagnetic catapult, the curve overtaking will soon come true! The Ford's electromagnetic catapult is unstable, and the electromagnetic blocking is even more unworkable. Ma Weiming famously said: "Even if you live ten years less, you must also attack the difficulties of special power technology!" After five years of unremitting sprinting, Ma Weiming led the project team to complete the whole process of prototype development and testing. All 43 key technologies were conquered, and 32 national defense patents were declared. Seven academicians from the Chinese Academy of Sciences and the Chinese Academy of Engineering were excited when reviewing this major achievement, believing that the significance of this major key technology breakthrough is no less than "two bombs and one satellite" and manned spaceflight.
