That picture was discussed barely a day ago in the carrier thread, and several times before that. As conclusion goes, it may or may not be an EMALS testing facility. Some kind of catapult facility it is.
Well from this google translation seem emal to me. though at 3100 lb is it enough to pull the aircraft?
Just overcoming friction alone it need at least 20,000 lb Still in development stage? could be just laboratory set up . How old is this paper?. Or the paper only describe the theoretical study?. Many question unasnwered
China's new aircraft carrier catapult leads the world in the use of electromagnetic
Electromagnetic aircraft launching system - a key technology
The heart of the electromagnetic catapult is 100 meters long linear induction motor, driving the armature connected with the aircraft. At present, the armature is basically a U-shaped aluminum block, mounted on the stator of the three sides. The principle of linear motor is not complicated. Envision a rotation of the induction motor cut open along the direction of the radius, and flattening, which has become a linear induction motor.
In the linear motor, the equivalent of rotating the stator, called the primary; equivalent to rotating the rotor, called the secondary. In through the exchange of primary, secondary role in the electromagnetic force under the straight line along the primary campaign. Then the primary to do very long, extending to the movement required to reach the location, and the sub is not required so long.
In fact, the linear motor can either do a very long primary, the secondary can be made very long; both fixed primary, secondary move, can also be secondary fixed, the primary movement. However, the electromagnetic catapult is never linear motor work alone, it has forced a total energy storage devices, high-power electrical control equipment, industrial control computer and central linear induction motor.
A special type of ship electric power technology, only some developed countries to master. Ma Weiming rate of intellectual research group set, made with world advanced level of design. However, no one believes they can do it, because of our accumulated technology in this area is not enough. In response, Ma Weiming cross the next one mind: "Even a small live ten years, but also capture the power of special technical difficulties!"
After five years of hard sprint, Walter Ma led the project team completed a prototype development and testing of the entire process, 43 key technologies have all been overcome, to declare the patent defense 32. Chinese Academy of Sciences, Chinese Academy of Engineering academician seven significant results in this review are excited that this major breakthroughs in key technologies, its as important as the "bombs and one satellite" and the manned space flight.
