News: China to create the world’s leading aircraft carrier off the new way

see a few days ago, experts say China’s Varyag catapult can not be installed on the wonderful theory, I was very depressed, China’s brick home, why did the creativity and imagination do not, someone else in the flat deck catapult installed on the design, it is because the enzyme did not state the way the design slip flying leaps, leaps to fly slip does not mean that you can not install catapults, we have ready-made Varyag platform, the experts do not you he can not as an advantage? You can not design in the targeted surface deck catapult? Say the simple truth, the train car is straight, but it can turn along the arc of the rail, can train only on the flat rail to road? Only know to follow other people to go back, others do not necessarily invented it not do? I would like to install in the bottom of the deck surface on the same curve of the track, catapults moving parts of the orbital motion along the curve, as can be designed catapult, just as the train can turn the same.

Due to the sliding generated by the aircraft flying leaps Miguel, catapult straight stretch as long as there is enough to take off half way, instead of catapult design manufacture and installation easier, this slide plus flying leaps off catapult way they may be the best way to take off the aircraft carrier, when the enzyme to the States but also to go with it.

electromagnetic aircraft launching system – 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.

force energy storage device

force energy storage device is an electromagnetic catapult bottleneck in the defense has been highly confidential. Role is to normal storage, high-power energy in a short time and then released. Electromagnetic catapult working hours is not long, but time is the acceleration in the acting process of doing work, so it can not be considered as constant power devices.

electromagnetic catapult system to force energy storage system requires full within 45 seconds of energy required. The largest carrier-based aircraft took off normally will not need to consume more than 120 megajoules of energy, and this forced the largest energy storage system can store 140 MJ of energy, this time charging power of 3.1 MW, count losses of about 4 MW (in fact unattainable), four electromagnetic catapult system at the same time, charging the total power of up to 16 MW (1 MW=1000KW), shows no strong power is unable to meet the needs of the electromagnetic catapult. Of course, the carrier power is not limited to the four electromagnetic catapult, in addition to electromagnetic rail guns, lift, laser (laser power at present are not large), then the combined electricity and other carriers must be the total power of up to 60 trillion watts or more, or electromagnetic catapult charge of electricity will also affect other systems.

electromagnetic catapult challenge is not like steam power, is not suitable for large capacity storage, such as storing the energy carrier aircraft catapult even more difficult. General Atomics in the experimental electromagnetic catapult energy storage device when the mention of force, showing a high degree of confidentiality of its technology is unusual, but also easy to break.

central computer control equipment, electric power industrial control devices Linear Induction Motor

maglev linear motor is driven. In fact on the linear induction motor is simple in principle, in real life can be encountered many. The U.S. is the use of the elevator car door drive linear motor, while China has most of the parked cars on the bed, which are not too many occasions. For the electromagnetic catapults with them compared to the linear motor can be described as super-power, and its technology also higher than normal. Electromagnetic catapult is a linear motor mover aluminum tube (most of the material is aluminum), for the U-shaped, three of which face the stator linear motor with the relative, of which there is friction with the carrier back and forth Road, the rest will not generate friction and light weight aluminum barrel, far less than the steam catapult piston, so the return is very easy, slow channel can also be much shorter. In fact, part of which some experts believe that the promoter can be further reduced, then the efficiency of electromagnetic catapult is obvious.

guide

electromagnetic rail catapult the electromagnetic rail gun with very different than its more complicated.
electromagnetic rail catapult a total of four, respectively, the upper 2 and lower 2. But each with very long track (200 meters) off the deck installed in the following. And each have a superconductor with its internal rail welding, the middle is the high-pressure cooling oil, the cooling oil into the rail before the temperature is below -40 ℃, while exports from the rail temperature is below -30 ℃. Moreover, rail and aircraft drawbar center of the contact surface to the rail, there are many extra-fine holes, so its not just for superconductors cooled oil cooling and lubrication of the role, but will aircraft drawbar running when cool.

aircraft tow bar is in the air under the front wheel even with the aircraft as one of the devices can be placed in the plane of the contraction and the abdominal cavity. One room for superconductors, but the cold does channel oil and rail connections with the larger, are soft touch. Before takeoff, the aircraft out to the tow bar up and down between the rails, such as aircraft engine start and open run, but about one second when the catapult power, a strong current from the rail and then flows back through the other aircraft drawbar and the formation of the rail loop, traction bars in the strong electromagnetic force to run to the next is to promote high-speed (not yet reached takeoff speed, but only almost) after the current is forced to close, the tow bar will no longer force, but in the aircraft engine thrust to achieve take-off speed. Why does not meet the take-off speed to power it? Because the aircraft because the aircraft drawbar as a single entity and, if so then continue to power the plane will take off when the aircraft drawbar pull, power will produce a strong arc burns aircraft drawbar.

above process is actually a pulse generator completed. Steam catapult and the catapult to make the engine run simultaneously (shortened takeoff distance), the first block with a steel rod running the aircraft, aircraft engine thrust can not be inferred as steel rod, but it can be inferred together with the catapult steel rod, so that the aircraft together with the engine in the catapult to take off. However, electromagnetic catapults, but no steel rod block, when the plane took off simultaneously energized electromagnetic catapult, but the current is gradually increased up and take off the last paragraph in the current cut-off.

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.
