"Your lab is also researching communication satellites?" asked Qian Lao with a clear twinkle in his eyes.

"I have not studied satellites, but electronic communications, computer information processing and storage have always been the key scientific research projects of Tiangong Laboratory. Yang Weiping nodded and replied: "I think that the core of communication satellites is basically composed of these three parts.

Before I left Switzerland, I submitted a research document on the 'DRAM' technique to the Computer Research Department. I think that with the professional ability of the existing researchers in Tiangong Laboratory, it is entirely possible for them to understand the information I submitted. ”

"DRAM technique, what kind of technique is this?" asked Qian Lao in amazement.

"Dynamic Random Access Memory, which stands for Dynamic Random Access Memory, is called DRAM for short. Yang Weiping explained: "The main principle of this technique is to use the amount of internal memory to represent whether a bit is 1 or 0.

In reality, the capacitor will leak current, resulting in insufficient potential difference and memory loss, so it is not possible to ensure that the memory will last forever unless the capacitor is charged periodically and frequently.

Because of this need for periodic refreshes, it is referred to as "dynamic" memory. Comparatively, "static" memory is not lost even if it is not refreshed as long as the data is stored. The advantage of DRAM is that it is simple, and only one capacitor and one for each bit of data can be processed.

As a result, DRAM has a very high density, a higher capacity per unit volume and therefore a lower cost. If this technique is studied, a square centimeter size on a silicon wafer. A minimum of 350,000 transistors can be integrated. ”

"One square centimeter integrates thirty-five million transistors?" Qian Lao asked with a look of shock in his eyes, "Is this the application of nanotechnology?"

"Well, at present, the research of Tiangong Laboratory in nanotechnology is mainly focused on silicon table crystalline tubes. Yang Weiping nodded and said: "If this project can make a breakthrough, it will mark the development of LSI and enter the highest stage of the VLSI stage!"

"Wei Ping, this is an epoch-making invention!" Qian Lao said ecstatically: "If this technique can be applied to rockets and satellites, our launch vehicles and satellites will become smaller and lighter, and their performance will be more powerful!"

"The skills that Tiangong has represent what Huaxia has!" Yang Weiping said as he looked at Qian Lao firmly.

"Good boy, it seems that there are still a lot of good treasures hidden in your Tiangong laboratory!" Qian Lao smiled happily.

"There are a lot of good things. But if you want to come up with breakthrough results, you have to burn a lot of US dollars in it!" Yang Weiping suddenly felt that the money in his pocket was not enough.

In the previous life, the DRAM technology was first invented by the little devils, and then resold to the United States, and Intel Corporation, which got this technology, has since entered a stage of rapid development.

The little devil also has mastered this technique, which makes it have an absolute advantage in the electronics industry.

Yang Weiping is not good at electronics and microelectronics, but he has looked up DRAM-related information. What is the principle of Zhilu Dao? Therefore, he wrote a research material related to DRAM technology. It was handed over to Bern Steve and asked him to focus on all the electronic and microelectronics experts in the laboratory as the core key research project of Tiangong Laboratory.

Yang Weiping believes that as long as these electronic and microelectronics experts understand the principle of DRAM technology, coupled with nanotechnology, supplemented by Switzerland's precision processing technology capabilities, Tiangong Laboratory's advantages in integrated circuits and computer chips will be unsurpassed!

It is also because Tiangong Laboratory is making every effort to overcome DRAM technology. Yang Weiping had the confidence to say to Hughsfeld that he must get the phone out.

At that time, the Huaxia electronics industry, which has mastered DRAM technology, will definitely be able to hold the little devil up in the market of electronic consumer products such as stereo radios, color televisions, and cassette recorders!

The three of them whispered as they rode out of the Yang family's estate, escorted by three Land Rover military off-road vehicles. Drive quickly towards downtown Nairobi.

……

Chinese Embassy in Kenya.

Ambassador Wang Yueyi warmly received the scientists of Yang University.

Tang Weimin entered the secret room to talk to China, and Yang Weiping chose to avoid leisure very interestingly, and chatted with Qian Lao about rockets.

Qian Laozhi said that Yang Weiping's parents were involved in Huaxia's "two bombs and one satellite" project back then. It is not surprising at all that Yang Weiping knows some technical knowledge of rockets and missiles.

After chatting for a while, Yang Weiping suddenly asked: "Uncle Qian, how is China's research on hypersonic combined air-aspirated engines progressing now?"

"You are also involved in this kind of scramjet engine?" asked Qian Lao with obvious surprise.

"Well, I know a little bit. Yang Weiping nodded modestly and replied.

"Just a few breakthroughs have been made with monolithic liquid-fuel ramjet engines. In terms of supersonic combustion, the intake duct and combustion chamber are not very effective because of some aspects of material and design. Qian Lao said in a somewhat heavy mood.

The key to achieving hypersonic flight is the power provided by scramjet engines. The working premise of a scramjet engine is a hypersonic air intake with reasonable design and excellent performance.

Yang Weiping knew that the several types of air intakes that Qian Lao had mastered at present were external pressure air intakes with a single cone, multi-shock wave air intakes, side air intakes, and isentropic air intakes.

"Uncle Chamber, I know a little bit about the P2 and P8 air intakes of a hypersonic cruise missile with a speed of Mach 12 that NASA is working on. Yang Weiping said with a deep sigh: "At present, the design of the intake tract of scramjet engines in Europe and the United States is mainly divided into three types: axisymmetric, two-dimensional and three-dimensional. ”

Ten years of turmoil made Qian Lao basically blind to the development of foreign missiles, and when he heard Yang Weiping say that it was a hypersonic cruise missile with a speed of up to Mach 12, he immediately became interested.

Therefore, Yang Weiping shared some of his experiences and ideas on axisymmetric air intake, two-dimensional air inlet and medial three-dimensional air intake with Qian Lao in detail.

Listening to Qian Lao's fascination, with his rich knowledge of aerodynamics, it is not a point to penetrate, drawing inferences from one another, and from time to time he also puts forward some of his unique opinions, so that Yang Weiping has to admire that top experts are top experts.

It can be said that this conversation opened a new door for Qian Lao's research and development of the air intake tract ahead of schedule, so that Huaxia's missile research and development was completed at least five years earlier than the original history!

The sharing on their side had just come to an end, and Tang Weimin also came out of the secret room after making a phone call.

"Wei Ping, China has agreed to your suggestion. Tang Weimin said excitedly: "I was ordered to go to Tanzania immediately." ”

"Well, in this case, Brother Tang, I won't accompany you to Tanzania. Yang Weiping nodded and said, "In order not to affect our trip back to China, it is better for us to go separately." When the time comes, you invite a few people in charge over, and I will meet with them to discuss the specific matters of the project. ”

"No problem, I'll leave immediately!" Tang Weimin said categorically.

When Qian Lao went to the secret room to make a call, he specially called Yang Weiping over to observe.

Of course, this kind of opportunity to observe Europe's most advanced communications satellites will not be missed. Not only can you learn the current advanced technology in Europe, but you can also earn a considerable amount of foreign exchange, and you must have agreed.

Anyway, the satellite is to be transported back to the Huaxia mainland for launch, and there is no need to worry about any leaks of Huaxia's rocket technology and launch base.

After getting a definite reply from China, Yang Weiping let go of another matter, and he was naturally in a good mood.

After returning to the manor, Qian Lao went headlong into Yang Weiping's laboratory, and with the help of various advanced instruments and equipment in the laboratory, he immediately began to design and calculate the new air intake.

Yang Weiping did not dare to influence the achievements of Qian Lao in his previous life, he knew very well in his heart that as long as Qian Lao mastered the design principles of axisymmetric, two-dimensional, and three-dimensional inlet air intakes, Huaxia's achievements in scramjet engines would be the same as the original history, and Huaxia's missile and rocket technology could reach the most advanced level in the world.

In the future, the new high-temperature and high-pressure alloy materials provided by him will be used, and then it will definitely be able to add wings to the tiger and shock the world!

The next day, Hughsfield came earlier than Yang Weiping expected.

He had just finished his morning exercise and sat down for breakfast in the cafeteria when he heard Hughsfield shouting all the way to "break in" in the dust.

Hughsfeld didn't say anything polite to Yang Weiping, picked up a glass of milk that Yang Weiping was about to drink on the table, raised his head and drank it in one gulp.

"I said, Field, you didn't take a flight to me overnight last night, did you?" Yang Weiping smiled and waved his hand to the maid to add a breakfast to the guest.

"Yang, if you go to Taiwan to invest in such a big thing, of course I can't slack off, not for a minute. Hughsfeld said quite seriously: "I heard that Chiang Ching-kuo, the supreme leader of Taiwan, has personally come to Kenya to visit you. I estimate that the scale of your investment in Taiwan will definitely exceed that of Kenya. ”

"Hehe, Field, it seems that your news is as well-informed as ever. Yang Weiping smiled and nodded and said: "Your speculation is not wrong, in the future, Hong Kong and Taiwan will be an important springboard for us to base ourselves in Asia and enter the mainland Chinese market." ”

"Has the Huaxia government already sent someone to contact you?" Hughsfeld asked confusedly, "Aren't you going to invest in Huaxia?"

"Go, though, it won't be very big for the time being. Yang Weiping nodded, raised his right index finger again, shook it gently, and said, "Field, if you are interested in the Huaxia mainland market, you can consider going to Huaxia with me this time." ”

"In your words, it must!" replied Husfeld without thinking, "I said that wherever you invest, even if it is hell, I will follow your pace!"
