Back to the Republic of China to be a editor

"Old Lu, you can just call me Tang Hua. Did you find the problem from the source and solve it, or did you modify the parameters at the end?"

"It's the source. The calculation of the aerodynamic lift change value when the missile's angle of attack changes."

"Just need to change the fire control computer, and don't need to change the missile design?" Tang Hua was also very happy to hear the news, "That's great. Did the laboratory test pass?"

"The test was passed 5 minutes ago, and it was successfully resolved. ... What I want to ask is, does Beijing still store the test bombs used to hit low-altitude balloons? Or should we install the new fire control computer and take it to the test site to have a shot?" ?”

Of course Tang Hua knew that Lu Xiaopeng wanted to watch the missile test right now.In fact, Tang Hua wanted to see it himself.But not today.

……

"Tang Hua, the Bureau of Nonferrous Metals Industry has made a construction assignment for the aluminum industry. You come to review and approve it. If there is anything to be adjusted, you can adjust it and pass it to Wang Yiqun after the revision. The assignment has been sent to my office for two days. , let the secretary send the document bag of the assignment to you now."

Who else could call from Shanghai? Of course, it was Vice Premier Chen and Minister of Heavy Industry.

"Yes. But Vice Premier Chen, can't the task force be handled by the secretariat?"

"This is one of the first batch of key projects aided by the Soviet Union. In theory, all projects must be reviewed and approved by the leaders of the Ministry of Heavy Industry. The Secretariat can't sign for me, but you or Liu Nai can."

Liu Nai, another deputy minister of the Ministry of Heavy Industry and director of the General Administration of Ordnance Industry, was entangled in the expansion of the production of 40 fire and 108 rockets in Dalian, and he was completely unable to get out.

The chief accountant couldn't get away in the South.The chief accountant is now, um, somewhat acting as part of the prime minister's job.

The Prime Minister is governing the Huai River.

In the summer of 1950, severe floods occurred in the Huaihe River Basin. More than 10 breaches along the main Huaihe River above Hongze Lake caused 1300 million people to be displaced.Then there was the first Huaihe control meeting of the Government Administration Council. The chairman proposed that "in addition to the current prevention and rescue, radical measures must be considered. Preparations should be started now. A large-scale Huaihe River diversion project will be organized in autumn. It is expected to complete the Huaihe River diversion in one year and avoid flooding next year. ", and then the "Decision on Harnessing the Huaihe River" in October.

At this moment, the Prime Minister is in the mud along the Huaihe River, with one foot deep and the other shallow, re-checking the historical water level and flow of the Huaihe River with the hydrometeorological observation personnel.These works accumulated and became the basic reference data for the Subei Irrigation Canal (forcibly dug an outlet for the Huaihe River).

These are all the scenes that Tang Hua saw from the world-famous painting in the Zhihuai Memorial Hall.

So, now Tang Hua wanted to complain, but he couldn't say it.Military electronic technology is to be done...he must also take care of the affairs of other industrial bureaus.

Open the "Aluminum Industry Restoration and Construction Task Book", this should be the first "156 projects" project report that Tang Hua came into contact with.

In fact, "156 Projects" was not called "156 Projects" at the beginning.The Soviet Union aided the construction of China's basic industrial system. Since the first batch of projects started in 1950, the intermediate plan was revised and expanded several times. By the end of the 50s, we counted and there were 156 key Soviet aid projects, so we used this Written in the history books as a name. (In fact, Gannan Power Station was changed to Chengdu Power Station, and Shaanxi 422 Plant was counted twice, so there are actually 154 items).

When the Chairman visited the Soviet Union in 1950, it was agreed in principle that the Soviet Union would help my country rebuild and expand large-scale aluminum factories.This is part of the huge system project that the Soviet Union aided China in establishing the aviation industry.The first batch of projects also identified 16 Soviet expert design teams, who have completed more than 20 key projects in China.

The aluminum industry projects aided by the Soviet Union also included Benxi Alumina Mine, Jilin Carbon Plant, Zhangdian Alumina Plant, Fushun Electrolytic Aluminum Plant, and Harbin 101 Plant (aluminum processing).

At the end of 1950, the aluminum industry design team sent by the Soviet Union—more than 40 nonferrous metal experts and smelting experts had arrived in the Northeast or were on their way to the Northeast.

After these projects are completed, China will have a basically complete aluminum industry system.

Now to build the Hongqi-1 air defense missile, we have to buy 30 tons of aluminum-magnesium alloy in advance and store them in Dalian.In the future, China will be able to produce as much aluminum as it needs, which makes me very excited to think about it.

Tang Hua saw that the project task book also includes the production of metal magnesium. After all, most aviation aluminum alloys are aluminum-magnesium alloys.Northeast China is currently the region with the most abundant power supply in China, which can provide power support for high power-consuming industries such as magnesium and aluminum.Since the power supply is abundant...how about reserving a factory area for electrolytic refining of silicon in the future?

The current transistor is supported by a small silicon germanium factory in Kunshan. If the computer and electronics industry continues to develop like this, the production capacity of silicon germanium in Kunshan will become the bottleneck of the entire industrial chain in about 1952~1953.

So Tang Hua picked up a pen and inserted a paragraph in the task book, asking Fushun to prepare for the establishment of a large-scale refined silicon production facility in Fushun with the help and guidance of Soviet experts and technical experts sent from Kunshan to tackle key problems for the next generation. One-step "silicon special refining project" is ready.

Refined silicon and future monocrystalline silicon require a lot of electricity, and it is safer to allocate some of them to the Northeast.

……

Ming Tombs missile test site.

Tang Hua and Lu Xiaopeng took the test convoy and set off from downtown Beijing. After bumping on the road for three hours, they came here to set off firecrackers at the emperor's grave.

The big truck behind Tang Hua's jeep were four photographers from Beijing Film Studio and their photographic equipment.Now Beijing Film Studio is actually very average. At this time, the two major players in Chinese movies are Shanghai Film and Changying. Beijing Film Factory has not produced any good films for the time being. It is also good for the missile test site. It finally has something to do.

The four photographers who were seconded are now in mixed moods.On the one hand, this work is mysterious and exciting. In their understanding of the world, it seems that no matter in China or abroad, there has never been such a "biu" that dragged the flames and sent the small balloons floating in the sky far away. Explosive weapons.On the other hand, they are all participants in the secret national defense project now, and their activities are no longer free.Before participating in the project, I checked the three generations of my ancestors. After joining the project, I reported my whereabouts and contacts every day. As for leaving Beijing to go to other places, I didn’t even think about it.

Behind the camera vehicle is the missile system, and the launch vehicle, radar vehicle, and ammunition loading vehicle are all covered tightly with tarpaulins.

"Balloon team, wait a minute, Lao Lu is going to your place." Tang Hua told the balloon team not to release the balloons through the walkie-talkie.

Lao Lu climbed up the mountain. Under his guidance, the balloon team tied seventy or eighty red cloth belts on the rope tied to the balloon at intervals of 2 meters.This can play a role in roughly marking the distance in the pictures taken by the photography team. When watching the film playback of Beijing Film Factory afterwards, how far the missile was from the balloon at the moment of explosion, and how much the deviation distance was, you can use the red cloth on the rope The number of nodes with partitions is estimated.

"Attention all units, launch countdown, immediately enter the shelter."

The anti-aircraft missile fire control radar aimed at the sparkling floating air balloon. A moment later, the launching vehicle parked 30 meters next to the radar vehicle made a thunderous sound, and the Hongqi-1 anti-aircraft missile jumped into the sky and flew towards the target just like the last time. go.

"Did it hit directly?" Observing from the artillery mirror, Tang Hua felt that the missile pierced the balloon directly.

"You still have to watch the film playback to be sure. But the deviation of the missile is really not big." Lao Lu said, "I saw the film of your last test launch, and the deviation seems to be larger than this time?"

"It is obviously bigger than today, and it is fixed to the upper left." Tang Hua said.

Today, I will not play the balloons with the ultra-low altitude clutter background. The four balloons are all low-altitude balloons released from the top of the mountain.

"Three of the four missiles had no obvious deviation, and one missile had some deviation, but it did not deviate from the fragmentation radius of the warhead." Lao Lu concluded after statistics, "These days the fire control computer software The improvement and adjustment of the hardware should be effective."

Documentary viewing room.

"For the first shot, r is 11 meters, φ is 25 degrees, and θ is 11 degrees."

After the four rolls of film were developed, the project team directly cut the copies, released them frame by frame like a slide, and then estimated the amount of deviation.

"Second shot, r is...r is less than 2 meters! φ...θ..."

r is the linear distance between the bombing point of the missile and the balloon, and φ and θ are the azimuth and elevation angles of the space polar coordinates.This second shot simply hit the balloon directly, and the amount of deviation was impossible to estimate.

After counting the four missiles, except for one missile whose r is 35 meters, the errors of the other three missiles are all less than 20 meters.

Now Tang Hua is waiting for the last live ammunition test: shooting a moving target drone.

Chapter 81, The Restricted Areas of Life

The winter of 1950 came fast and cruel.

At the eastern end of the Eurasian continent, seven US military divisions were lost in the snow on the Korean Peninsula.At this time, the United States Army had only 20 divisions, eight of which were urgently recovered from the reserve after August 1950.

In Europe, six years after the end of the war, much of Europe is still struggling to recover from tens of millions of dead and wounded.Marshall's massive aid program forgave the Allies' war-lease loans and poured tens of billions of dollars directly into Europe, but reconstruction did not happen overnight.In addition to getting Western Europe out of the Great Recession, the more troublesome issue is how to break down tariffs and trade barriers between countries.

In the Middle East, oil has not yet become a specialty here, and the population has long exceeded the limit of natural agriculture. In order to compete for the last piece of water and grass pastures, indigenous tribes use single-shot rifles and Arab machetes to kill you and me.

Just after the founding of the Republic of India, it was involved in the complicated ethnic and religious conflicts with Pakistan. The minefields planted by Lord Mountbatten on the South Asian subcontinent have exploded almost every five years since then, and the rumble has continued into the 5st century.

In the cold winter wind, the official residence in Taipei across the strait was heavily guarded. Chiang Kai-shek sat in the hall, holding the prime minister's last instruction and the agreement, muttering to himself, "One year prepares for two years of counterattack, three years of mopping up and five years of success..."

At the end of 1950, mankind had completed half of the twentieth century.Looking back on the past 50 years, it was the two world wars that destroyed two generations, a flu that killed as many as the world wars, the disintegration of ancient countries, more and more advanced and efficient killing weapons, and the United States. The cycad curtain and the nuclear bomb hanging over the heads of all mankind like the sword of Damocles.

If there were self-media in 1950, many literary youths would cry and say, "Let's read the archives and start again in the 20th century. The past 50 years have been terrible."

In the cold winter wind, few people noticed that a highly classified radio wave was sent from Taipei, and the telegram was received and translated by a radio station somewhere in Tokyo.
