The second small trailer was empty, and the satellite must have been pulled to the next door for testing.The same satellite is on the third small trailer.
"One, two, three, four, five, six, the first batch of satellites is ready." Tang Hua said.
Qian Xuesen looked up to the sky and sighed: "Tang Hua, the spaceflight of the Soviet Union and the United States is to compete for space and expand the boundaries of civilization for all mankind. Your spaceflight is purely for commercial interests."
Tang Hua laughed when he heard this: "That's really the case. As long as there are 20 paying users, the project will pay off. The country squeezes out a little money from the construction industry to develop the aerospace industry. We will use this If we spend some money to explore the universe, we must also allow aerospace to contribute to the country’s development and construction, and it is best to export aerospace products and services. With direct economic benefits, it will be easier for our aerospace development plans to be approved in the future.”

The site of the Canton Fair in Guangzhou, the staff are nervously arranging the venue, the Canton Fair in the spring of 1959 will be held in early April.
The regions where China exports commodities and agricultural specialties have not changed from last year.In terms of industrial products, in addition to the traditional series of small radios, tape recorders, electric fans, and rice cookers, there are also some new products.In the most conspicuous area in the center of the industrial product hall, there is a large high platform, and the staff are struggling to lift up a metal object that looks like a large trolley case.
This trolley case has a smooth appearance and shiny paint, but there is not much explanatory text, only a LOGO of the electronics industry, and a line of English:
Sextant
There is also a striking price tag on the high platform, with the number written: $399,800
Tianjin Rocket Factory.
"One, two, three, four, five, six, the launch vehicles for launching your batch of satellites are ready." Qian Xuesen said.
Tang Hua looked at the giant assembly workshop of the rocket factory.Of the six rockets Qian Xuesen pointed out, the first two have been formed at the end of the workshop, two are still in a state of assembly, and two are in a state of disassembled parts.
"This is Long March-2, what about Dongfeng-3?" Tang Hua asked.
"The first Dongfeng-3 bomb was taken to Wuliangsuhai, and the second one was tested next door. They are all combined first-level and second-level bombs, and the second one is in full condition, with a simulated warhead."
Tang Hua: "Go to Wuliang Suhai, you are doing a high-trajectory test."
Qian Xuesen: "Since the progress of the atomic bomb office is still on schedule, I think the full trajectory test of Dongfeng-3 can be delayed a little bit. Anyway, the success of the high trajectory test means that Dongfeng-3 has passed in a 95% realistic environment. Tested. Probably not just 95%, but 98%."

After boarding the train from Tianjin, Tang Hua continued to walk towards Shanghai.
At the same time as Tang Hua's Tianjin-Shanghai trip, the special plane of the Prime Minister and Mr. Chen flew from Beijing to Guangzhou, and then flew from Guangzhou to Jakarta.
Nehru's special plane will also arrive in Jakarta on the same day.
The prime ministers of China and India will hold their first high-level meeting on matters in southern Tibet.
Before leaving for Jakarta, Nehru asked the Indian Ministry of Defense to send an infantry division to Assam, which means to be ready to attack Derangzong and Bandila at any time.
It was the end of March, and no matter how closed the news in India was, New Delhi knew that the Chinese army had crossed the Himalayas and occupied four towns in southern Tibet.
After getting the news, Nehru summoned the Chinese ambassador to India three times within five days, but in the Indian parliament and high political levels, a unified opinion could not be formed for a while.
Southern Tibet has not yet established a separate state, but a central special administrative region of India.
Southern Tibet is indeed rich in rain, but the problem is that it is too abundant. If there is no modern tropical agricultural technology, the reclaimed cultivated land (terraced fields) will be washed away by huge amounts of rain, and it is easy to lose fertility or simply suffer from soil erosion.So this special administrative region in southern Tibet has a relatively small population and is very poor.
Throughout March, the Indian media was furiously denouncing China, while high-level officials in India were trying their best to suppress and appease public sentiment, because the parliament had not yet been able to discuss the final opinion.
In the Indian Parliament, nearly half of the members said they would take back the four towns by force, but one-third of the members firmly opposed it.The rest of the MPs are yet to stand.
However, the Indian Parliament has discussed it for half a month, and the members seem to have forgotten the most important party-the Indian soldiers who were wiped out and captured by our army in southern Tibet.In Tawang, our army dispersed hundreds of Indian troops, captured more than 150 people, and killed more than 30 people. In Derangzong, 27 people were killed and 9 people were captured, and in Bandila, 37 people were killed and 90 people were captured.

Shanghai.
When Tang Hua arrived in Shanghai, he thought that the main members of the ship research institute must be circling around the Type 58 destroyer on the berth, but it turned out that it was not.
In the factory area of Jiangnan Shipyard, in a large workshop, Tang Hua met a group of designers led by Cheng Wang.
The workshop was very noisy, and everyone was staring at the working area of the workshop. Tang Hua also looked over. There was a large four-axis CNC milling machine produced by Shanghai Heavy Machine Tool Factory (Shangsan Machine), and the milling cutter was rattling. There was a noise, and a large piece of bronze was being milled.
The cutter head seems to have eyes and a brain. Every time it passes through the air, it follows a precise trajectory, and then sticks to the bronze surface. The milling cutter rotates while doing three-dimensional movements, scraping off a piece of the bronze surface. Then the cycle repeats.Tang Hua looked at it for a while, and gradually the shape of this piece of bronze could be seen, it was a propeller blade.
"How is it? Mr. Makino," Tang Hua asked, "the Heavy Machinery Bureau is very supportive of the shipyard, right? High-precision milling machines, lathes, planers, boring machines, bending machines... and new gantry cranes. The first Type 58 After the destroyer is completed, starting with the second one, its propellers can also be replaced with new forms of propellers."
Tang Hua, Cheng Wang, and Makino Shigeru walked out of the workshop with their ears quiet. After listening to Tang Hua's words, Makino Shigeru thought for a while, and then simply replied: "Section 28.8."
Tang Hua: "?"
Makino Shigeru: "In the original computer fluid simulation and pool ship model test, we calculated a speed of 28.5 knots, but now it seems that it is not. With the output power of the main engine at 72000 shaft horsepower, its speed is not 28.5 knots, but should be It's 28.8."
Tang Hua nodded: "Indeed, the propulsion efficiency of this kind of propeller will be improved, and the noise will be reduced."
What is being processed in the workshop is the propeller of the [-]-ton cruiser.
After it enters service, it may surpass the "Long Beach" and become the cruiser with the strongest comprehensive air defense capability, but it may also be the slowest cruiser in the world.
It uses the main engine on the Type 56/Type 58 destroyer, two steam turbines, each with 36000 horsepower.The power generation capacity of diesel engines is quite sufficient, with two medium-high-speed engines and four high-speed engines, but now there is neither electric propulsion nor an integrated power management system, and the electricity generated will not increase the propulsion power.
Shigeru Makino: "Just as China monopolizes computer technology, does China have an exclusive monopoly on CNC machine tool technology?"
Tang Hua: "We are only ahead of other countries in computer technology, not that other countries cannot manufacture computers. For example, the United States is imitating our computers. The same is true for CNC machine tools. CNC machine tools have appeared in the United States, but they are not widely used and there is no We have such a complete system."
Since transistors and computers can be manufactured, the United States has indeed successfully developed CNC machine tools.Moreover, on the basis of imitating China's second-generation transistors, several companies in the United States have been trying to make smaller transistors since last year.
Tang Hua estimates that the United States has taken a step forward in semiconductor technology in the last year or two.
Several companies are trying to make smaller transistors, so there is a high probability that a company will appear that wants to use planar etching to process silicon wafers and then cut them into particles to make transistors.The fabrication of transistors by planar etching process is the pre-technology of integrated circuits.
However, after the window paper was punctured, China did not have to be so twisted when it comes to exporting electronic products... This can be regarded as both good and bad.
As for CNC machine tools, the United States originally developed the first CNC machine tools with vacuum tube computers in the mid-50s, and there is no way to engage in any technical blockade.However, from 1954 to 1958, China developed the milling machine from three-axis linkage to four-axis linkage. In this regard, it can still maintain its technological advantage.

Cheng Wang: "Minister Tang, the navy has initially decided that the first cruiser will be named Type 59, and the first ship will be named 'Jiangsu'."
Tang Hua: "Jiangsu? How good it is to be named after a city. And if a Jiangsu is created, who will support the commanders and fighters on the ship in the future?"
Cheng Wang: "Cities are destroyers, and large warships such as cruisers use the names of provinces...Let's name them like this first. Commander Xiao said that if there is any confusion in the future, the naming regulations can be adjusted."
This is how the Type 59 Jiangsu-class cruiser was born. The propellers are being processed in the workshop, and the keel has been laid in the 200-meter slipway.
The bridge designed by Makino Shigeru has a Japanese tower style, but it also fits the antenna surface size of the first-generation phased array radar.The standard displacement is 10140 tons, and the full-load displacement is 12720 tons.
The performance is similar to the regular powered version of the Long Beach class, or the earthy Ti Conderoga, but Tang Hua thinks it is closer to the latter, because the Jiangsu class does not plan to install ultra-long-range anti-aircraft missiles with a range of [-] kilometers and an impressive hit rate.
"Mr. Makino, in fact, there is still a system for the Type 59 cruiser that has not been developed yet," Tang Hua said, "Its software. But I believe that the Shanghai Computer Institute will complete the software compilation as scheduled."
Chapter 214, the plane crashed, I hope everyone is okay
At the Jiangnan Shipyard, the most spectacular scene Tang Hua saw was not the Type 58 destroyer under construction, but the construction of a 3000-ton inland river freighter at the same time on three berths of the Jiangnan Factory; two 200-meter docks, one of which was building the cruiser Jiangsu , and another dock is building a 1.6-ton bulk carrier.
