He has seen the panda before, when he took his daughter to the Bronx Zoo many years ago. It is said that it was a gift from the Republic of China to the United States during World War II. I like it, and I bought a panda plush toy for my daughter before leaving.

But the panda in the dream is not cute at all, in fact its expression is very lewd.

The panda with a lewd expression walked up behind Oldford with aggressive steps, and whispered in his ear: "Hey, the missile that killed Arthur Trudeau was not guided by TV. "

! !

So what is this thing I developed? !

Oldford woke up with a fright.

After waking up from the shock, Oldford tossed and turned in bed and stayed up all night. Now he has become a panda, with black circles around his eyes.

Oakes said confidently, "We've found the right direction," which reminded Oldford of the nightmare of last night.

No...really...wrong direction?

Forget it, don't think too much, because if you think too much, you won't be able to sleep at night.

……

9 am. The weather in Area 51 is sunny and cloudless.The AD-12 with the AGM-4 mounted is activated and rises into the sky from the end of the runway.Flying over Area 51, an instruction from the ground command center came from the radio, indicating that everything in the shooting range in Area 51 was normal and that weapons launch tests could be carried out.

In the shooting range of Area 51, there is a scrapped truck parked on the hard ground in the middle of the desert. This is the ground target that the AGM-12 missile will hit.In order to make it easier for the TV guidance system to aim at this ground target, the test team cheated a little by painting the truck a blue hue with a bright purple fringe, which stands out against the tawny desert background.

The ground command center announced that "it can be launched", the pilot pressed the launch button, and the AGM-12 was released from the belly of the AD-4, and a long flame was ejected from the tail and flew forward.

The maximum flight speed of the missile is close to the speed of sound, and the maximum range is 25 kilometers. If it is launched at high altitude, the range will be slightly increased.However, the longest video communication distance between the missile and the transmitter is 40 kilometers, so the range cannot be infinitely increased by increasing the launch height.

The missile is launched, and after stabilizing its flight attitude, it enters the mid-flight stage. The missile transmits video image information, and the transmitter sends radio instructions. high dive...

As soon as this altitude dropped sharply, the missile fell straight down from a height of 100 meters and exploded on the top of a large sand dune.The point where the missile landed was 3 kilometers from the truck.

Hearing the voice report from the radio station, Oldford pulled his few remaining hairs.

"Have confidence in yourself, have confidence," Oakes shook Oldford's shoulders, "A total of 2 missiles will be launched in the Phase 6 test, and we only look at the sample statistics, that is the real hit rate."

When the first AD-4 returned, the AD-4 with the second test bomb mounted had already taken off.

The test process of the first aircraft was exactly the same. The second aircraft flew close to the test site of Area 51 and launched missiles.The missile flew all the way along the predetermined trajectory, caught the target and dived, and directly hit the blue truck parked in the desert. The three-ton truck was blown away by the blast wave, more than three meters above the ground, and then fell heavily beside the road.

……

On April 4, the test firing of six missiles over two days ended.

"The first and fifth missiles were lost, and the remaining four missiles destroyed the target. Two of the missiles hit the truck directly."

The hit rate was 66%, greater than the 50% figure originally expected. The test firing of "Phase 2" is basically a pass.

Not only Oldford was relieved, but Martin Marietta and even the U.S. Air Force breathed a sigh of relief.It took more than three years and $4900 million to develop a mission that overwhelmed a medium-sized company and bankrupted it. The result is that now the US Air Force's air-to-ground conventional weapons have finally entered the ranks of precision guidance.

As for what, it can only attack during the day?No matter what night combat is now, isn't it enough to blow up a truck from 25 kilometers away?At least you can tell Congress what the $4900 million was spent on, right?

Besides, infrared TV cameras are not without ideas, and they are already doing it now.

Shanghai.

"One of the first things that must be solved by the billion-time supercomputer is whether the chip can run at high frequencies. The high frequency mentioned here is 40 to 80 megahertz. If the chip can reach such an operating frequency, our next work will be You can continue, otherwise you can only continue to wait for the improvement of the chip and basic device level."

Tang Hua first talked about the long-term planning of supercomputing, and then planned the development route for this long-term goal.

Li Qiang: "The chips that need to be able to run at high frequencies here are not just arithmetic processors, but include all semiconductor devices inside the computer, including arithmetic processors, shift registers, standard memory chips, I/O access converters, etc. .All must be able to operate at high frequencies, and this technology span is relatively large.”

Xie Xide: "The 6-micron chip has been mass-produced at the end of February, and the yield rate is not bad. This is also the technology we have planned for the T2 computer. The current research direction of the Institute of Computer Science and Hon Hai, the 57-micron process is an early stage. It has already started. Then Huang Kun and I did some theoretical research on this high-frequency chip in 5."

Huang Kun: "What I imagined at the time was the change in the operation of the devices inside the chip when the operating frequency reached 100 megahertz."

Tang Hua: "I have read this paper. Last year it was theoretical research, and this year you have the opportunity to practice it. In that paper, it seems to focus on high-frequency environment operation. An inevitable problem encountered by chips is heat? "

"Yes. The increase in operating frequency and the increase in current make it difficult to suppress the heat inside the chip, and it will definitely generate a lot of heat."

Li Qiang: "The heating problem is inevitable, so we use engineering design to solve the heating problem. Copper or aluminum heat sinks, forced ventilation cooling, or even water cooling mode can all be considered."

Tang Hua: "The chip set can take 4 to 5 months to complete the high-frequency technical problems. I mean other problems to be solved except heat generation. Lao Lie and Wang Shoujue, from now on, the architecture design of supercomputers can also be solved. Parallelism started, so that when the technology of high-frequency chips made a breakthrough, the research on the architecture of supercomputing was also halfway through.”

Lebedev: "If the supercomputing architecture plan is started now, then it may be necessary to let the supercomputing user, the meteorologist named Zhu Kezhen, join the research team."

Tang Hua: "Does Zhu Kezhen need to intervene so early?"

"Of course."

Tang Hua: "The person who needs supercomputing most now is Zhu Kezhen, but in the future it's not just him who needs supercomputing... I will find a way to get Zhu Kezhen to come to Shanghai for a few months. I will also get some other people. "

……

The first supercomputing meeting is over.

At present, the operating frequency of the X5500 series chips is at the 1MHz level, and it needs to be increased to 40~80MHz at once, which is a huge span.

Cray-1 was developed in the mid-70s. At that time, high-frequency device technology had already achieved a breakthrough, and Cray did not need to do it by itself.It is now 1956, and China has to break through the high-frequency ceiling first.

But now there is a theoretical basis, so Tang Hua set the time for the second supercomputing meeting in September this year, and gave them 9 months to solve this problem.

……

In the spring of 1956, the wharf on the Huangpu River in Shanghai was quiet, but the shipyard was not.

Maritime trade has not recovered in general, and the volume of shipping is not large.All goods that need to be imported and exported by sea are transited through the ports on the west coast of North Korea in Shanghai and the north. North Korea also gets a lot of labor fees for this, and the gray business in the south relies on Hong Kong, a transit point.

In the years when shipping was in recession, dock workers who should have been unemployed were reemployed under the arrangement of the city government, and shipping trading companies were also transferred to other businesses under the arrangement of the government. Let an old company go bankrupt and dissolve.

In the era of sluggish shipping, Shanghai's shipyards still have business.In addition to destroyers and frigates, there are also short-term ferry ro-ro ships and bulk carriers from northern coastal ports to North Korea. These 4000 to 6000-ton civilian ships can already be built by Shanghai itself.

It is not only built by China itself, but also designed by the Shanghai Design Institute of the Shipbuilding Industry Bureau.

"Mr. Makino, you have been in China for more than two years, and the brand-new ships you have designed are only two types of [-]-ton freighters. Do you feel a bit boring?" Tang Hua asked Makino Shigeru with a smile.

"Strictly speaking, this is an era where swords are turned into plows. At least China is in an era of peace, so I have no regrets," said Shigeru Makino. "And I have always believed that China will go to the ocean and become the top of the sea power club." Members, time will tell."

Tang Hua nodded, "That's good, we will have more time to refine our design... After the design of the 5000-ton destroyer leader ship is completed, the first machine bureau, the second machine bureau, and the electronics industry bureau will add to it. Some things formed the outline of a destroyer. Today, this outline can be fully displayed."

Chapter 122, Fertilizer Battle

Makino Shigeru and the comrades of the ship design institute have been concentrating on designing the ship type of the new destroyer for the past two years. Most of the time has been devoted to line simulation and testing. Only after the weapon is determined can we know.Now Shigeru Makino finally knows what warship he is designing.

...However, this blueprint and model are still only a blueprint that may be realized in the near future. Just as it is impossible to start construction of a 5000-ton destroyer immediately, the things installed on the model cannot be taken out immediately.
