Super Copy of Great Power Technology

Qiao Ruida stayed in Academician Wang's office for less than ten minutes before he was pulled into the chip laboratory by his senior Zhou Wanda to help his seniors solve problems in the production process of graphene chips. This small-scale graphene chip production line in the laboratory was donated to Peking University by Qiao Ruida. The production capacity is not very high, but the specifications are not low at all. After debugging, it can produce graphene chips below 3 nanometers. At present, many professors and scientific research teams in the education system will choose to come here for tape-out testing of graphene chips designed by them. Because it is non-profit, the price is much cheaper than the quotation from Rockchip Foundry.

Since this set of equipment was copied by Qiao Ruida, he was familiar with the technical details of each device and was able to answer questions easily. Qiao Ruida answered all the questions raised by more than a dozen seniors, including graduate students, lecturers, and even professors and associate professors of chip-related majors at Peking University, in just two hours. This move stunned all the seniors, and they looked at Qiao Ruida with admiration and surprise.

"I told you that my junior brother is a genius in chip design and production, but you didn't believe me. Now you have seen how powerful he is. Those difficult problems that you couldn't solve no matter how hard you thought or how much brainstorming you all put together, my junior brother can give the correct answers without even having to think!" Zhou Wanda said with some pride.

"Yes, Junior Brother Qiao is really amazing. It seems that no problem can stump him. In comparison, I, as your senior sister, have been in the industry for more than ten years, but now I am like a beginner and cannot understand some basic principles."

"It's not our fault. The chip technology is changing too fast. Last year, silicon-based chips were still popular. If we could master the 14nm process, we would be able to catch up with the mainstream process, and if we could master the 7nm process, we would be the world leader. Who would have thought that only half a year later, Rockchip Foundry would launch a graphene chip, which is much better than silicon-based chips in performance, with very low heat generation and power consumption. It has replaced silicon-based chips and has become the development direction of the chip industry."

"Chips are at the forefront of science and technology, so it is reasonable that the technology is updated faster. We professors and lecturers must keep up with technological changes and master the latest and most complete knowledge system. Only in this way can we impart correct knowledge and concepts in the teaching process and avoid misleading students."

"Professor Wu is right. Complaining is useless. If you have the time, you should study hard."

"Junior Brother Qiao, why don't you open a graphene chip design course in our department and explain the powerful performance and design basis of graphene chips to those undergraduate students."

"Yes, Junior Brother, your Ruida Group has launched Ruida EDA software that can be used for graphene chip design and simulation, but there is no user manual, no training materials, no explanation videos, etc., and everyone has to learn by themselves. When encountering some problems, you can only rely on your own exploration and attempts, which is very difficult. If you can open a graphene chip design course at our Peking University, and then record it and put it online, it will definitely be beneficial to promote your EDA software and increase the market share of graphene chips."

Facing the requests from his seniors to teach, Qiao Ruida helplessly spread his hands and said, "I also want to contribute to the promotion of Ruida EDA software, and teach a course in our department. But I really don't have the time. I have to study graduate courses on my own, do various experiments, and manage a large group company. I really can't do it in two places. How about this, I will introduce two graphene chip design experts from Ruida Research Institute to come to our Peking University and give a few lectures. Then open a forum related to graphene chips to help everyone answer questions and facilitate mutual communication."

"Well, it is quite necessary to open an official forum so that engineers who are self-taught in graphene chip design can have a place to communicate with each other, learn from each other's strengths and make progress together."

"It's easy to give a lecture at Peking University. Just send me the information of the two researchers and I'll send them an invitation letter in the name of Peking University's Microelectronics Department."

After answering the questions from his seniors, Qiao Ruida put on his dust-free suit and walked through the graphene production line from beginning to end, correcting the parameter settings of some equipment. After the adjustment, the effect was immediate, and the chip yield rate increased by more than 20 points. When the test results were statistically analyzed, the teachers and students in the chip laboratory almost dropped their jaws.

Zhou Wanda gave Qiao Ruida a thumbs up and praised him, "Brother Qiao, you did a great job. We have been debugging this production line for several months. After the yield rate reached 60%, it was difficult to make any further progress. We thought that this graphene chip production line was a test line with limited potential after all, and 60% was the upper limit of the yield rate. Unexpectedly, it was not that the production line had exhausted its potential, but that our technology was not up to standard. Now that you have adjusted a few parameter settings, the yield rate has jumped by more than 80 points to more than %. This operation really turned decay into magic, comparable to a divine move."

"Junior brother, what is the upper limit of the yield rate of this production line? Can it reach 90%?" asked another female associate professor.

Qiao Ruida nodded affirmatively and said, "The yield rate of our graphene chip production line in Rockchip Fab has now increased to over 95%. Theoretically, this experimental line has higher precision and automation than the mass production line in the factory, so the yield rate should also be higher. It is only 83.5% now, which is still far from the limit."

Adjusting the graphene chip production line sounds simple, but it is actually a very complicated process. It was already evening when the final test results were obtained. Seeing that it was getting late, Qiao Ruida said goodbye to his fellow students and Academician Wang and left the laboratory building. Zhou Wanda and several fellow students accompanied him to the bottom of the laboratory building before waving goodbye.

In the next few days, Qiao Ruida was basically running between the company and the school, and was extremely busy. It was not until the end of 2014 and the arrival of the New Year's Day holiday that Qiao Ruida finally had some free time. He accompanied his girlfriend shopping, watched the latest holographic 3D projection blockbuster, and drove to the south bank of Miyun Reservoir to go fishing and camping. Only three days of vacation was enough for Qiao Ruida and Du Qingqing to have a good time.

During the New Year's Day, China's military industry broke out big news again. The J20 stealth fighter, which is still in the test flight stage, ushered in the second major change. Not only was it replaced with a new type of engine, but the fuselage also underwent major surgery, the air intake was cancelled, the ammunition bay was expanded, and the wings were also reshaped, making the lines look smoother and the curves more beautiful. Photos of the revised J20 were posted on the Internet by some "lying grass party" and "climbing wall party", sparking heated discussions among military fans. Related videos and photos were widely circulated, especially the words "anti-gravity engine" on the banner at the scene gave people endless reverie.

In fact, testing the J20 is not uncommon, but the matching engine is the focus of everyone's attention. As a fifth-generation stealth fighter, the J20 did not originally have a domestic engine. At that time, due to the high pressure of the surrounding environment, the fourth-generation aircraft such as the F-15 were already full of the streets, and the F-35 was also equipped and put into service one after another, which has a cross-generation advantage over the domestic J10 and J11. In order not to fall behind seriously, the J20 directly uses the Russian-made AL-31F engine, taking a place in the fifth-generation aircraft in the fastest time, making my country the second country after the United States to equip the fifth-generation stealth aircraft, which is the top priority.

But its drawbacks are equally obvious. Since the Russian-made power performance does not meet the design indicators, the J20 cannot exert its greatest advantages, its maneuverability is limited, and it cannot achieve the supersonic cruise that is standard for the fifth-generation aircraft, just like the last link in the martial arts novels that has not been opened before the Ren and Du meridians are opened. Therefore, while the equipment is being tested, the research and development of the J20's standard engine WS-15 is also in full swing. Just when everyone thought that the next major change of the J20 would inevitably be equipped with a domestically produced high-thrust WS-15 engine to achieve the goal of a true fifth-generation aircraft. Suddenly, an "anti-gravity engine" emerged, which was the first to be installed and tested, and the J20 aircraft structure was greatly changed. There are too many things worth discussing.

"The changes to the J20 are too big this time. Even the air intake has been cancelled. If I hadn't seen the familiar 2021 fuselage number, I would have thought it was another brand new aircraft."

"Can someone explain to me what an anti-gravity engine is? Can this engine provide thrust without taking in air?"

"Anti-gravity engines, as the name suggests, are engines that shield part or all of the gravity of the aircraft and provide a certain amount of thrust. Before this, this type of engine has always existed in science fiction works."

"I think I've seen this kind of engine chrysanthemum that looks like a gas stove somewhere. Oh, and isn't this the anti-gravity engine that Ruida Aerospace uses on its space shuttle? Comparing the pictures of the two, not only are their shapes completely unrelated, they are exactly the same."

"If it is really the anti-gravity engine provided by Ruida Aerospace, then the new version of the J20 fighter will be very interesting. Maybe it can fly out of the atmosphere and into space."

"It is common for military aircraft engines to be modified and used in civil aircraft. This is the first time that a civil aircraft engine has been directly used in a military aircraft. We are witnessing history today."

"If the revised J20 really has the ability to fly in space and its flight speed is increased to hypersonic level, it will become a sixth-generation aircraft."

"The anti-gravity engine is truly the greatest invention of the 21st century. Once this technology becomes popular, flying cars, flying motorcycles, and even flying skateboards can all be expected."

"Oh my god, the latest video is out, the new version of the J20 actually has the ability to take off and land vertically. This anti-gravity engine is really not called that for nothing."

"I just watched the latest video. The J20 is very stable in vertical takeoff, much more stable than the half-baked F35C of the ugly country."

"In that case, this new version of the J20 may be deployed on ships. Although the Liaoning is a little old and does not have a catapult, it can still defeat the U.S. aircraft carrier battle group if equipped with the vertical take-off and landing version of the J20."

"According to my analysis, the J20 equipped with the anti-gravity engine has the following advantages over the old version: first, it has stronger stealth performance, is not easy to be captured by radar, and is not easy to be tracked by missiles. Although the working principle of the anti-gravity engine is not clear, when it is working, the heat generated must be much smaller than that of the turbofan engine, so those infrared-guided missiles will be useless against the J20. In addition, the cancellation of the air intake can significantly reduce the radar reflection area and enhance the stealth performance of the fighter. Secondly, the aircraft ceiling is greatly increased, and even the possibility of entering space is retained. When the anti-gravity engine is working, it does not consume air. Even if the new version of the J20 flies to the edge of the atmosphere, there will be no thrust drop or air buoyancy drop. It can fly higher, far exceeding the flight altitude of traditional fighters. In addition, the new version of the J20 has a greatly increased bomb load. It can be seen from the leaked photos that after the air intake was cancelled, a large part of the vacated space was converted into a bomb bay. Visually, the bomb load has at least doubled. The anti-gravity engine has the function of isolating gravity, which means that as long as the bomb bay can be loaded, it will not be overloaded even if it is full."

"The new version of the J20 has a lot of room for imagination. With a little modification, it is possible to develop a carrier-based version, an aerospace version, or a bomber version."

"I don't know how much the anti-gravity engine costs, and whether it will continue to be decentralized. If our Air Force's current J-10, J-11, and even the J-6 and J-8 are all equipped with anti-gravity engines, the improvement in our military's combat power will be unimaginable."

In the next half month, the new version of J20 began intensive test flights, and the number of test aircraft quickly increased from one to three. As more videos and photos were released, everyone once again witnessed the power of the anti-gravity engine. The performance of the revised J20 is amazing. It can take off and land vertically, and the requirements for the site are extremely low. As long as there is a flat open space, it can take off and land. The flight speed has increased significantly, and completing supersonic cruise is just a piece of cake. Flying at three, four, or even five times the speed of sound has also appeared in the video many times. The new version of J20 only uses electricity and does not burn oil. The fighter's requirements for supplies have been reduced again. Any place with electricity can be used as a supply point for the J20.

The news related to the new version of J20 has not only been seen by domestic military fans, but also spread abroad through the Internet, which has attracted widespread attention from Western developed countries, led by the United States. Their people and experts are studying the authenticity of these videos and photos and analyzing the performance of the new version of J20.

Some spies lurking in our country have also taken action, trying every possible means to find technical information about the anti-gravity engine and the new version of J20. I don't know what the situation is in other places. Suspicious people have appeared near the Ruida Group headquarters, Ruida Aerospace City, and Ruida Rocket Manufacturing Factory, trying to approach or even sneak into the company to steal technical information.
