Chapter 343 YM-12

In the B-level base, the original parking area was covered by a new factory building with freshly dried paint, and giant devices were transported, lifted and installed one by one.

The technicians from the Fourth Hospital and the 601st Institute were dumbfounded as they watched a super monster begin to be assembled, and they were all in a state of extreme shock.

What is being assembled in this factory is a hydraulic die forging machine YM-12 with a weight of 30,000 tons and a pressure of 120,000 tons.

120,000 tons hydraulic die forging machine!

The world's number one before it was the 80,000-ton hydraulic die forging machine manufactured by China, and before that was the 75,000-ton die forging machine manufactured by the former Alliance 47 years ago. There are also tens of thousands of tons of die forging machine manufacturing capabilities in the world. The only ones left are Ami, Aoguo, Lucia and Huaguo.

The YM-12 directly broke the previous record, making the pressure of a human hydraulic die forging machine exceed 100,000 tons for the first time.

YM-12 is nearly 40 meters above ground, more than 18 meters underground, and has more than 60 individual parts weighing more than 100 tons, directly setting a new historical record.

YM-12... When was the YM-12 project established? Last October.

Since Serev took over the engine and overall design of Tengyun Engineering, the biggest problem has been body weight control.

How can an aerospace aircraft with a take-off mass of 200 tons, which can travel between the sky and the earth, be reused more than 100 times, control its empty weight to less than 35 tons?

It is barely enough in terms of materials alone, but it is an unprecedented challenge for the processing technology. It is required that the body made of difficult-to-process materials must be integrated as much as possible to reduce the mass while maintaining strength.

There are two ways to process such a difficult body: 3D printing or integral die forging.

The current technology of 3D printing is not enough, and the material requirements are more troublesome, so the suitable solution is to use an ultra-high pressure die forging machine to process it, which is fast and can ensure strength.

The domestic 80,000-ton hydraulic die forging machine is barely enough, but it has too many tasks. Since it was put into production in 2013, it has received countless tasks. The plan has been scheduled for two years, and there is no way to squeeze it. If you don’t have time to serve Tengyun, you will have to wait another year even if you jump in the queue.

Serev couldn't wait any longer, so he tried to use the research institute to find the ideal die forging machine of over 100,000 tons. Unexpectedly, the design work was completed with almost no money, and he immediately began arranging parts for production by workshops and suppliers.

In order to ensure efficiency, two An-1250 aircraft transported parts directly from the manufacturer. The terrifying load capacity basically solved the transportation problem of all parts, and it was easily solved when they arrived at the base.

The main force also involved in the design of the Tengyun project were elite designers from the National Aeronautics and Space Administration and the 601 Institute. They had been designing the body part in accordance with Serev's requirements on their own sites. They originally thought it would be a long-term project of at least four to five years.

As a result, last month, the TP-25 "Lushan" engine successfully tested at the desert base and perfectly met the technical requirements. They were shocked. They couldn't believe that an engine with this "cobbled together" working method could really work. Stable operation.

As the eldest son of the Republic of China's industry, Institute 601 is actually quite arrogant. After losing the fifth-generation fighter competition, they changed the "97 Plan" they bid for and spent 9 months to build the second fifth-generation fighter, the FC31 "Falcon". "Eagle", this is just what they, a production consortium, did with their own strength!

So when I learned that I was going to help Serev in the Tengyun Project, I was very unconvinced. But the moment I saw the TP-25, all doubts disappeared, and I was left with admiration like looking up at a miracle.

Later, Serev said that partial trial production of the machine body could be carried out, saying that the base already had a solution. They thought it would be some strange innovative route, but they did not expect that a miracle would occur with great efforts.

The 120,000-ton hydraulic die forging machine is more than enough to process Tengyun’s high-strength body. Of course, it can also process large-scale marine spindles, ultra-high-strength spacecraft parts, etc.

But, it only took more than five months to build this thing? !

"Mr. Xie, this, this is really..."

The researcher at Institute 601 was speechless as he pointed at the YM-12. The super die forging machine appeared silently. This was simply too scary.

Serev: "This is not my fault. I designed the aircraft. YM-12 is a project of the Medium Machinery Department, and many domestic manufacturers are also involved in the manufacturing. They were basically involved in the previous 80,000-ton die forging machine. "

"But, but..."

Serev: "Okay, okay, has the optimized design of the wing spar I requested been completed? That is the main area that withstands high temperatures and pressures. It doesn't matter even if it adds a little weight, safety must be ensured. This is a passenger aircraft."

…

Florida.

"A 54-year-old white man raped an alligator? Oh my god, Bezos, is it because the environment here is so unreliable that your HLS is so unreliable?"

Jim Free brought the NACA support team to Blue Origin to check the technical status of the "Blue Moon" lander and investigate the cause of the engine failure during previous tests.

During a break, Jim watched the latest local news and complained about Jeff Bezos, his younger brother, Mark Bezos, who is still under the careful care of his personal doctor.

Mark Bezos is slightly embarrassed because the "Blue Moon" lander cannot be described as perfect at the moment.

"Blue Moon" was originally scheduled to be completed in November, but now NACA is trying to advance it by at least three months. However, during inspection, it was found that there are still quite a few problems.

The first is the overall design. "Blue Moon" weighs 45 tons when fully fueled. Obviously Aramco does not have any rocket that can launch a fully fueled "Blue Moon", so the original plan was to launch an empty lander and then a space shuttle. Give it fuel.

Obviously this plan won't work. That was what we were talking about when we were trying to draw the pie. At least it's definitely too late now.

The Falcon Heavy is not reused at all, and can send up to 22 tons of mass, which means that Blue Moon can carry 8 tons of fuel, which is obviously not enough.

The original plan was to use the New Glenn rocket developed by the Blue Origin project or another heavy-lift Falcon to complete the fuel. There would be no need for a space shuttle. It would be refueled in orbit. Even if the refueling is not full, it would be enough. At worst, some load would be reduced.

Now that "New Glenn" has entered the specific design stage because of the successful test run of BE-4, there is definitely no chance. The Falcon Heavy... that means almost consuming all of SpecaX's Falcon 9 to build the Falcon Heavy booster. , Lao Ma will definitely be happy, but he will have to pay more.

There is no other way. The SLS rocket can also be used, but obviously the manufacturing capacity is limited and it cannot be done.

NACA has now reached an internal agreement and is ready to notify SpecaX to build the Falcon Heavy and the fuel tank. Anyway, NACA now has sufficient funds, and it is not a problem that can be solved with money. At least the CBC configuration of the Falcon Heavy is much faster to produce, directly Active Falcon 9s can be mobilized.

At the same time, Claire is also secretly contacting the four crew members of the Artemis program.
