This star is going to the moon

Chapter 173: "Cloud Climbing" Engine, Sam's "Chandrayaan-" Makes a Shining Debut! (Birthday Vote Request)
Nearing midnight, the Bluestar Aerospace Intelligent Manufacturing Base and the adjacent integrated test center were still brightly lit.

Although there are only dozens of space launches in China each year, it is not because there are fewer things that need to be launched, but because the speed of rocket production cannot keep up, resulting in a large number of spacecraft waiting in line for rockets.

Blue Star Aerospace joined in last year. Even though the first stage of the Wanhu rocket has been reused, it only needs to produce more second stages. However, the number of rocket launches is still not enough, and there are still a large number of spacecraft waiting in line.

Therefore, the second phase of the Bluestar Aerospace Intelligent Manufacturing Base has begun.

At the same time, with the increasing demand for testing of the "Fangfei-70" engine and new engines, the comprehensive test center is also being expanded.

A huge aerospace production base is rapidly taking shape.

In the busy aerospace base, Lu Yun was also busy with the linear piston engine working group.

The linear aerospike engine used by the Kite is actually similar to the XRS-33 hydrogen-oxygen linear aerospike nozzle engine used by the unfinished X-2200 verification aircraft of the United States, with a thrust of more than 200 tons.

However, due to the different times and the advanced technological knowledge in Lu Yun's mind, the problems of XRS-2200 are no longer problems.

For example, a linear aeroplane engine is actually composed of many small engines, and the flames they eject will work along the "V" slope to generate thrust.

This makes the engine much more compact than a bell-nozzle engine, and allows it to operate at the optimal expansion ratio at various flight altitudes, greatly improving its operating efficiency.

In addition, since this engine has multiple thrust units and the flow rate can be changed by computer electronic equipment, multi-axis directional control can be achieved without using a very bulky mechanical steering mechanism.

But because of this, the two slopes may be operating at different thrust and temperature levels at a certain moment, so the cooling problem is difficult to solve.

There are many ways to cool traditional rocket engines. One is to let liquid hydrogen fuel flow in the cooling tubes of the nozzle wall to achieve cooling. At the same time, the preheated liquid hydrogen can also better enter the thrust unit for combustion.

However, the only problem is that compared to traditional rocket cooling pipes that are relatively easy to manufacture, the cooling pipes of linear air plugs are more complicated and very difficult to manufacture.

Now, metal 3D printing technology has gradually matured, and many complex structural components of rockets are already being manufactured using metal 3D printing technology.

Road Cloud has more powerful technology, combined with the country's increasingly powerful industrial capabilities, so more complex structural components can also be manufactured using metal 3D printing.

He is sure that even if the Americans restart the X-33 space shuttle project, the linear aeroplane piston engine will still be a problem.

After all, he is cheating!

Now, after listening to the reports one by one, Lu Yun signed the checklist and said, "No problem, we can test drive the whole machine tomorrow!"

"Whoo~"

All the staff on site breathed a sigh of relief and were also a little excited because this day had finally come.

Or rather, this day has arrived so soon!
"I still find it hard to believe that we actually developed a linear piston engine that even the Americans couldn't successfully develop!"

"Hey, that's not very accurate. The American XRS-2200 isn't 100% complete yet, and the same is true for ours. After all, we haven't even tested it yet. We won't know for sure until tomorrow whether it's 100% successful."

"Indeed, although the data seems to be fine, especially the data signed and certified by Mr. Lu, we really need to test drive the car to know for sure."

"That's definitely no problem. Let's wait and see what Mr. Lu will name it tomorrow!"

"Hey, what do you guys think Lu Zong will name it?"

"Maybe we'll refer to the 'Fangfei-70' and name it 'XX-220', since they both have engines."

"I think it will be based on mythology or history. After all, this is a groundbreaking linear aeroplane engine. Unlike the 'Fangfei-70' which has the successful 'Merlin' engine, it has a precedent. Especially since President Lu named the domestically produced Starlink 'Zhou Tian Xing Dou Da Zhen', I think its name will be similar to that."

"Okay, okay, stop guessing. Go back and take a shower and go to bed. I'll be in top form tomorrow for the full machine test."

"Hey, look at Weibo, our CEO Lu has done something big. I knew 'Flying-70' wasn't just a simple pun birthday gift for CEO An!"

"Why is there still this thing about President An... Holy crap, President Lu and President An have officially announced their relationship!" "Ah, do they even need an official announcement? Doesn't everyone in the company know about it? They look so adorable together... A talented couple, a beautiful woman! A match made in heaven!"

After all, most of the people in the aerospace base are science students. Even if they are eating sugar in private, they will not be as crazy as the CP fans on Weibo. At most, they will say "congratulations" when they see Lu Yun, and then throw themselves into busy work.

Of course, they are indeed busy with work, unlike those idle people who post on Weibo about "buying a house and settling down".

So the next morning, after breakfast, Lu Yun walked to the test bench control center while hearing "Congratulations" all the way.

"Automatic detection is normal. Turn on the machine, Mr. Lu?"

"Power on!"

"Understood, turn it on!"

“5、4、3、2、1，点火！”

"boom--!"

(Net map)
Originally, the first full-machine test run would not take too long, but after Lu Yun looked at all the data, he was very confident in the engine, so the first full-machine test run lasted only 120 seconds!
Looking at the engine running steadily, the staff at the control center became more and more excited and proud!

When the shutdown was successful, everyone burst into cheers!
“Hahaha, it really worked!”

"We built a linear air plug engine!"

"We are number one in the world. The Americans are nothing special. We easily beat them!"

"The future of human spaceflight is in our hands. I have no regrets."

"Mankind's dream of the stars and the sea is about to come true..."

"Stop, Mr. Lu has something to say. I guess he wants to announce the name..."

Seeing the silence at the scene, Lu Yun said, "In Journey to the West, the founder jokingly said that the flying skill that Sun Wukong had just learned was not 'soaring on the clouds', but only 'climbing on the clouds'. I think we are similar now."

"To put it bluntly, a linear aeroplane engine is still a rocket engine, and a space shuttle equipped with it is still a space shuttle. It's almost like the 'cloud climbing' technique that our ancestors used to talk about, so I call the linear aeroplane engine 'cloud climbing'."

"Now is not the time for complacency, comrades. Simply 'climbing the clouds' will not fulfill humanity's dream of reaching the stars and the sea. We must also 'soar'."

Upon hearing this, the quick-thinking people blurted out, "Is that 'Tengyun' at the back a space plane?"

Lu Yun did not answer, but turned on his acting skills and gave everyone a mysterious smile.

"Okay, don't worry about the future, let's take this step firmly now!"

Although Lu Yun didn't say it, his meaning was already quite clear, so the arrogant atmosphere at the scene was swept away, and everyone had more ambitious goals!
However, on the other side of the Himalayas, India's aerospace circle was in an uproar.

Chandrayaan-2 is about to be launched, allowing the world to witness the power of the Ganges!

Our Chandrayaan-2 is a completely domestically developed mission and represents Bharat's impending emergence as a superpower!

[Chandrayaan-2 will land at the South Pole of the Moon and release a lunar rover, an absolute first for humanity!]

【The moon will be ours! 】

[Chandrayaan-2 will complete the most lunar landing records using the least amount of money, so it is more powerful than Chang'e-4! ]
