Tang Hua told the chairman the truth about the affairs in the Soviet Union when he came back, and then there was the chaotic scene of the meeting above.
This is very confusing, not only the chairman, but also the prime minister, vice chairman Liu, Li Fuchun, and the chief accountant.
This meeting deliberated for a long time, and the chairman finally agreed to take a step back and write an article, emphasizing internally seeking truth from facts, emphasizing self-criticism, and making preventive beatings; he also said that "this kind of thing should not happen in the Soviet Union", but Don't mention Khrushchev's name.
……
In June, leaving Beijing, Tang Hua got off the train in Shijiazhuang, and the group headed for Taiyuan in two jeeps.
The spring drought lasted until the beginning of summer in June, and it was another dry season in North China this year.On both sides of the road from Hebei to Taiyuan, many millet and wheat fields are not healthy, but these crops are still struggling to survive.Walking for a kilometer or two, you can see farmers irrigating their fields. Some divide the water beside the diversion canal, some directly carry water to irrigate with ladles, and a few communes even drilled motorized wells to pump water for irrigation.
"This year's weather is still bad." Tang Hua said with emotion.
"My hometown ate yams for half a year last year," said the secretary. "It hasn't rained since the snow melted in spring, and the overwintering wheat seedlings are dying. After that, I can only replant yams."
The Taiyuan Space Launch Center has set up a new site near the control center to store the wreckage of the rocket pulled back from [-] kilometers away.
Ren Xinmin has been waiting in Taiyuan to recover the wreckage. Qian Xuesen arrived here a week earlier than Tang Hua. When Tang Hua came, all four twisted and broken boosters had been recovered, and the parts of the main rocket body were piled up. Trying to piece together a recovery.
Tang Hua: "How is it? Is there any clue about the cause of the failure?"
Ren Xinmin: "It's early, there are still three wreckage trucks on the road. After finding them all, we will investigate them one by one."
Chapter 47, From Two Bombs and One Star to Two Bombs and One Boat
"The news sent back to the country by the foreign affairs department. At the end of last month, Kennedy announced in a special meeting of the Senate and the House of Representatives that his government will fully support the Apollo program. The goal is to send people to the moon within 10 years. Before the Central Committee I just got the news a few days ago."
In Pingyao, Tang Hua, Qian Xuesen, and several main players in the aerospace department were discussing the American Apollo program.
"Nie Shuai knows the news, but Nie Shuai does not intend to take any countermeasures such as returning to Beijing for a meeting of the whole system," Tang Hua said, "Kennedy said that the United States is going to go to the moon, so let the United States do it. Our plan is not Make changes."
Qian Xuesen: "They just sent people into suborbital orbit at the end of April. The Apollo program is not a small technological span for the United States."
Tang Hua: "The United States is currently implementing the Mercury Project. The first stage sends people to suborbital orbits; the second stage sends individual astronauts to real low-Earth orbit. After the Eastern Project, there will be the Sunrise Project, and the United States’ corresponding spaceship project, they themselves are still not quite clear about it.”
……
"I believe that this nation can come together to achieve the goal that by 1970, man will land on the moon in a spaceship and return safely."
"No space project can surpass its impact on human beings, its significant role in remote space exploration of the universe, and no space project is so difficult and expensive to develop..."
In the U.S. Congress, Kennedy’s plan aroused applause—although the senators felt that the money spent on this plan was astronomical, but once the moon landing was successful, the prospect was too tempting:
If human civilization is still continuing 5000 years later, and humans want to write a brief history of mankind 5000 years later, there are probably only two things worth recording in history books in the 20th century:
The most significant event was the Apollo moon landing, the first time that human footsteps set foot on another planet other than Earth.A lesser event than this, but one worthy of entry in the history books, was Yuri Gagarin's entry into space.
Although it is "just an honor" which country sent humans to the moon, the weight of this honorary title is so great that people have to grab it.
When NASA was established a few years ago, some companies were designing a single F700 engine with a thrust of 1 tons. The Saturn 5 was not more than ten times larger, but a monster 20 times larger than the "Atlas" rocket.
Next year, the United States will develop the successor of the Atlas/Atlas rocket, the "Titan"/Hercules, with a diameter of more than 3 meters, no bundled booster, and the carrying capacity is only at the level of the Long March-3.
In addition to Hercules, the United States also has two series of Delta rockets and Saturn-1 rockets that have been launched or are about to be launched, but even if it is the largest Saturn-500 rocket with a weight of more than 1 tons, it is no problem for the Long March-3K4 to surpass it.
Then in 1966, American launch vehicles suddenly jumped from these small and medium models to the Saturn-5.
"If the United States wants to land on the moon, they will have to design a super-large rocket after the Mercury project," Qian Xuesen said. "I have been imagining the situation of landing on the moon for the past year. I am afraid that this rocket will be better than their "Atra" rocket. "The rocket is ten times bigger."
Tang Hua: "Old Qian, you're actually planning a spacecraft to land on the moon?"
……
I'm afraid I'm afraid.
Qian Xuesen not only conceived in detail the moon landing rocket and spacecraft in his eyes, but also wrote this thing into his book "Introduction to Interstellar Voyage".
The content of "Introduction to Interstellar Navigation" in this plane is more imaginative, but because the first few chapters involve Long March-2 and Long March-3, these already existing launch vehicles that require data confidentiality, they cannot be published publicly.
According to the operation mode of rockets and spacecraft, Qian Xuesen divided the moon landing into four types:
Direct round-trip type; Moon separation and docking type; Low-Earth orbit docking assembly type; Low-Earth orbit assembly + Moon separation and docking type.
A direct shuttle would require a rocket too large to be feasible.
The type of separation and docking around the moon is the model of Apollo-11.
Segmented launches and splicing the moon-flying rocket and the spacecraft together in low-Earth orbit can make the rocket smaller, but the effect is limited-the 80-ton moon-flying rocket must be a whole, and the other is a 30-ton heavy rocket. spaceship.I can build something with a capacity of 80 tons in low-Earth orbit, so why not add oil and make it 100 tons.
It is too complicated to assemble and separate once in the low-earth orbit and the orbit around the moon, which is prone to problems and is not feasible.
"We still want to be more realistic," Tang Hua said. "The current key project is the Long March-3K4. The progress of this must be guaranteed. It can be postponed for a few months, but it is best not to postpone it beyond 1962. The Long March-3 will be launched in July. Gaofen-3, this will be launched regardless of whether the cause of the failure of the Long March-4K[-] is investigated or not. But I may be on a business trip in the Soviet Union at that time."
Qian Xuesen: "Are there any cooperation plans with the Soviet Union?"
Tang Hua: "For manned spaceflight cooperation, the Air Force has begun to select pilots, and the other is cooperation in nuclear weapons. There may be a little bit of affairs with the Soviet Academy of Sciences."
……
Taiyuan 874 Machinery Factory (Taiyuan Torpedo Factory) and 872 Machinery Factory (small underwater power plant).
The Space Launch Center in Pingyao informed Lao Qian and the others that these two factories were the real purpose of Tang Hua's visit to Taiyuan.
鱼雷引进仿制计划1952年首次提出，其中有两三年工厂的引进计划处于暂停状态，到现在整整9年，874和872机械厂终于把53-39鱼雷仿制出来了。
53-39 torpedo, the first number indicates that the torpedo has a caliber of 533 mm, and the latter number indicates that it was finalized in 1939 and mass-produced around 1940.
This is a direct-flight torpedo with thermal power, which can sail at a constant depth, and can only be anti-ship, not anti-submarine.
It took 9 years to come up with this... It's okay, understandable.
Tang Hua didn't go to the 874 factory to slap the table and scold his mother. The two factories started construction from a wasteland and succeeded in imitating the 9mm torpedo in 533 years. This speed is actually not too slow.Thinking about the total investment of these two factories of 1.05 million yuan, including 5400 million rubles in foreign exchange, you can know the difficulty of torpedo manufacturing.
另一件事是，874厂在鱼-1（53-39鱼雷）的仿制工作进入收尾的时候，就按指令开始预研鱼-2双平面反潜/反舰线导鱼雷。
鱼-2大概等于热动力的MK37-1，或者像是双平面自导的53-39。
Now American attack nuclear submarines have used MK37/MK37-1 electric torpedoes. This torpedo can hit submerged submarines, but the maximum speed is only 26 knots, and warships sailing on the surface may not be able to catch up.Therefore, while the U.S. nuclear submarine is equipped with MK37, it must also install some MK14 direct flight torpedoes from World War II to anti-ship.
In the 874 Machinery Factory, Tang Hua saw the first sample of the Yu-2 torpedo.
"The power system and propulsion system have completed the high water pressure environment work test in the laboratory of our factory, but have not tried to do the sailing test at sea." Yang Han, the director of the 874 factory, briefly talked about the current status of Yu-2, " The Navy’s Sanya-Beibu Gulf torpedo test site will be opened in the second half of the year, and the torpedo sample mines will be able to conduct deep navigation tests by then.”
Tang Hua: "The high-depth pressure resistance of the Yu-2 mine body itself may be relatively simple. Whether the seeker can work normally at large depths is the difficulty. Liu Gong, what is the current state of the seeker subsystem? "
Liu Yu, chief engineer of the self-guided system: "The overall design has been completed, but some of the special components are still waiting for the delivery of parts from various factories."
Tang Hua: "You make a model of the seeker, and make the shell of the mine head, the pressure-resistant parts, the non-pressure-resistant oil/liquid chamber, etc. It doesn't matter if there is no chip or circuit in it, first install what can be installed. The things are installed, and then connected to the mine body, and we will do a large-depth navigation test together."
