Chapter 220 Pray for YF77
There is no doubt that China's semiconductor industry has undergone tremendous changes.
But this huge change is completely confusing to foreign counterparts.
Everyone knows what ternary system is, but now is 2016, not 1956 when computers were just starting to flourish. How can we go back to ternary system at this time?
Then he suddenly realized and took out the X321 series chips that Xinyuan has been selling for almost a year.
Since the X321 series chips are mainly used in automobiles and use 28nm technology, major manufacturers who have been working in the consumer market have not paid much attention to them. Now they have completely taken seriously this chip that has quietly entered the market.
At this time, Intel, which had been unable to hold back, finally responded first. One of its technical directors published a report on the technical analysis of the X32115 chip.
After the test by the technical director, the computing power level of the X32115 chip has exceeded that of the E5 2600 V4 processor that they are focusing on in the server market this year.
The technical director also speculated that because of the use of a symmetric ternary architecture, the X32115 can simulate some of the characteristics of quantum computers and has a miraculous effect in artificial intelligence computing, which is also the key reason why it can support its XW151 intelligent driving system with the current mainstream computing power.
The core conclusion of the report is: Damn it! The ternary system is revived, and it is much more powerful than binary!
This report instantly caused a huge storm in the industry, and then everyone went to dismantle the chips. Anyway, Xinan Automobile is not a sensitive item that can be bought casually, which led to a large increase in Xinan Automobile's overseas sales.
Then... there was an earthquake in the semiconductor industry.
On August 11, Qualcomm President Steve Mollenkopf flew to Maple Leaf Country, where 6 foreign mainstream chip manufacturers and 3 foundry companies will hold a "regular" exchange meeting for the world semiconductor industry.
…
There are still 22 hours before the launch of the Long March 10. Yun Hongjun led the entire R&D team to walk in the still busy assembly building, carefully avoiding the hurried staff.
In addition to them, people from several other institutes who participated in the Long March 10 were also there.
At the top, they met experts from the Fourth Academy.
The Fourth Academy is the Institute of Solid Propulsion Technology, so the question is, solid rockets are more expensive than thrust, so what kind of rockets will be used?
Of course, some small rockets that need to be transported by vehicles, so it is obvious that the Fourth Academy is mainly responsible for sending people to heaven.
But the escape tower part was still developed by them. The new generation of manned spacecraft is different from the second generation of spacecraft of Lao Ma, and it still continues the escape tower design. As for which one is better, it is hard to say.
The advantage of the spacecraft's own escape system is that it reduces costs and is simpler to reuse, but the disadvantage is that it increases dead weight and structure.
And the escape tower is theoretically safer, anyway, it is not too expensive, so safety is better.
But the experts of the Fourth Academy were still very emotional when they saw Yun Hongjun: "I really didn't expect that I could still participate in the moon landing project in my lifetime. I originally thought that I was going to develop boosters, but I didn't expect it was an escape tower."
Yun Hongjun knew what he meant. In the early days, the space agency planned to use the Long March 9, the successor of the giant rocket of the Dawn Project, for the moon landing. At that time, one of the configurations of the old Long March 9 was to use four high-thrust solid rocket boosters, which could definitely be used for the moon landing.
Unfortunately, the Long March 9 has been changed to a bare-barrel all-liquid engine rocket for recovery, and no expensive solid propulsion is needed.
"By the way, where is Old Tang? The Long March 10 is flying for the first time, won't he come to see it?"
The experts of the Fourth Academy suddenly mentioned Tang Weitian. As a key figure in the development of the YF130, it would be strange if he didn't come to see it at this time.
Yun Hongjun: "Old Tang? He seems to be training. He is about to go to the spacecraft. He may need to take care of his body more."
"..."
"I guess Mr. Yun will be going to the spacecraft soon, right?"
"Whether I can go up depends on whether the Long March 10 can go up. In fact, I would rather ride the Long March 10."
Yun Hongjun suddenly thought of John Blevins, who was announced by NACA as the chief designer of SLS to be sent to the moon.
Although he didn't know what Blevins thought, Yun Hongjun thought it was very exciting anyway. Being sent to the moon by a rocket designed by himself was even more romantic than poetry.
The rest of the people were all furious at Yun Hongjun's Versailles behavior, and simply changed the subject:
"I don't know how the YF77 performs. With a specific impulse of 430 seconds, it can actually increase the lunar orbit capacity to 50 tons if it tries hard. Burn it for a while longer."
"In theory, but I don't think we should rely too much on the YF77. This is our first open hydrogen-oxygen engine. Although the thrust of 70 tons is not small, the structure of the turbine pump caused by liquid hydrogen... I hope it is fine."
"Problems with the YF77 are minor, as long as the YF130 is fine."
"You mean..."
The minor matter of the YF77 is naturally meant to be meaningful, because the ideal second stage of the Long March 10 is actually the YF90, a single-combustion chamber 220-ton high-pressure regenerative liquid oxygen and liquid hydrogen engine, so it can also be replaced with a single engine.
If there is a problem with the YF77, it is easy to find a replacement: H240.
Xinyuan's 240-ton regenerative hydrogen-oxygen engine has flown twice on the second stage of the Xinyuan-3 and Xinyuan-2A. Its reliability seems to be good, so it can be considered as a backup option.
At the same time, Tang Weitian, who was training far away in the HD area, was thinking about the Long March 10. He had no worries about the YF130. The benefit of mediocre performance was that it was relatively stable. However, the Sixth Institute of YF77 could only say that it was 90% okay.
After all, the Space Administration did have little experience in the field of high-thrust hydrogen-oxygen engines.
He set an alarm for himself at 6 o'clock and got up early tomorrow morning to watch the first flight of the Long March 10.
And until late at night and early in the morning, planes kept landing at Qiongzhou and Sanya airports. They were all temporarily added flights, and they were all people who came to watch the rocket launch.
Compared with Xinyuan, the Space Administration's appeal in people's hearts is still very strong. The staff of Qiongzhou Airport looked at the crowded passenger channel and estimated that the number of people coming to this airport alone at night exceeded 20,000.
The Launch Administration knew that the number of people watching in the surrounding area might exceed 500,000 tomorrow.
Since last year, Qiongzhou's almost uninterrupted medium and large rocket launches throughout the year have become one of the characteristics of publicity. Basically, as long as you stay here for a week to ten days, you can encounter a rocket launch, and the number of tourists is rising steadily.
What is even more surprising is that according to internal customs statistics, among the foreigners who entered the country and intended to go to Qiongzhou to watch the rocket launch, the number of tourists from the island countries has increased to 20,000!
20,000 people!
Under the example of Zhang Chuanyong and Xiao Gangtian, more and more people from all walks of life have gone to China and intended to stay in the past four months.
The news of the upcoming maiden flight of the Long March 10 has no less impact on the island countries than on the mainland. In the past few days, even their national television station has focused on reporting it, and the supporters of Greater Asianism have expanded rapidly.
There was no organization to come to watch the maiden flight of the Long March 10 this time, it was all spontaneous behavior!
