Chapter 138: Building an Engine

That night, Hua Kejing habitually worked for two hours, and then trimmed a little and entered his own exclusive virtual world.

In the center of the hall of the small building on the second floor, the large screen was beating with updated mission information.

[Mission No. B001: Owns an aerospace technology company.] 】

Achievement Progress: 100 %.

Company name: Muyu Aerospace Technology Co., Ltd.

Time limit: within 1 month.

Rewards for completing missions:

Earn 200 technical points.

Master a professional engineering skill (professional optional, evaluated as a senior engineer).

……

Yes, the mission is complete, and Muyu Aerospace has been officially established.

Although it is still only a shell company, in the past half a month, Huakejing has let the most efficient headhunting team start poaching people, and I believe that there should be no problem in forming a basic engineering team within 3 months.

Unlike other private aerospace start-ups, Huake is not in a hurry to do PPT mixed financing.

According to the plan, he wanted to rely on his own strength to get Mu Yu's aerospace rocket out first.

Show your fists first, take out your strength, and make a splash, and we'll talk about the rest later.

Hua Kejing believes in a sentence, it's not that others help you to be a cow, but that others will help you after you are a cow.

Entrepreneurs who can only talk about cannons, draw pies, talk about visions, and do PPT are unqualified, and they have to be changed!

It's like someone said that Space X was cultivated by NASA (the old space agency), but in fact ULA (United Launch Alliance) is NASA's own son.

Remember that before the advent of Space X, ULA's offer for a launch rocket was $400 million, compared to Space X's $60 million offer for a commercial launch, which is simply not too good at grabbing money.

Of course, people have capital because his father is Lockheed Martin, the world's largest defense industry company, and his mother is Boeing, the world's largest aerospace manufacturer.

Whether it is Lockheed Martin or Boeing, they are all giants who have experienced World War I and World War II and created countless legends, and their customers are all national teams, and they have played all over the world.

How difficult is it to build a rocket?

The average person may not feel it.

Take the strongest king of the moment - the heavy falcon as an example.

Think about sending a 20-story building into space with 27 engines strapped to the back of the butt and giving her 2,280 tons of thrust.

And then, there are countless things that will never be known until the launch, because there are so many variables.

It's true that a single part can be tested over and over again, but a hundred thousand put the parts together and send them into the sky, and you never know what will happen.

Historically, there have not been too many "big fireworks displays" caused by all kinds of small details.

Factors such as wind, rain, temperature, speed, weight, air density, severe vibration state, etc.

With so many variables, if you don't launch and don't go into the sky, you can't test it at all.

However, the cost of the rocket is so high, the number of tests is bound to be less, so the ducks are rushed to the shelves, and various problems arise.

Believe it or not, every time I watch the live broadcast of a rocket launch, there are actually many people who have the mentality of watching big fireworks.

Fortunately, artificial intelligence has opened up a hook for Hua Kejing, whether it is to build a computing model and reset it repeatedly, or to launch rockets directly in the exclusive virtual world.

Muyu Aerospace's rockets can be tested again and again at zero cost.

This is what makes Hua Kejing's heart particularly down-to-earth.

Coupled with the blessing of the [Scientific Research Institute] and the [Engineering Research Institute], he can soon design and develop the top-notch, most powerful, and cheapest rockets according to different needs.

Of course, Hua Kejing's idea is that there is a universal rocket, can it be packaged and unified with small satellite rockets, large and small satellite rockets, lunar rockets, Mars rockets, etc., and do not develop a rocket for one purpose?

And if you go to space, can you fly up and back like an airplane?

The answer is yes.

Therefore, in the foreseeable future, Muyu Aerospace will definitely not just follow the footsteps of its predecessors.

If you want to lead, you must subvert and innovate!

……

"Little music."

"I'm here."

"I'm going to claim the reward for Mission B001."

"Mission B001: Own an aerospace technology company, done. Earn 200 technical credits and choose to master a professional engineering skill. ”

"I'm going to redeem my engineering skills."

"Please select the specialty you want to redeem."

In the virtual world, one person and one machine talk tacitly like this.

Xiaole doesn't like to talk nonsense, Hua Kejing is straightforward, this is a tacit understanding formed after several years of getting along.

Regarding the major of exchange, Hua Kejing has a plan in mind - aerospace engineer.

In fact, in Huaxia's professional title system, there is no aerospace engineer, because aerospace engineering covers a wide range of specialties.

But this is a personal ability evaluation system built by alien artificial intelligence, so there is, and the people who eat melons must be convinced.

The Aerospace Engineer is matched with the Faculty of Aerospace Engineering, one of the six departments of the Graduate School of Engineering, and is associated with the Faculty of Physical Sciences of the Faculty of Science.

So, after a familiar brain-irrigation program, Hua Kejing became a solid aerospace engineer.

Immediately after, a small screen popped up in front of his eyes.

It reads as follows:

[Engineering Technology Evaluation]:

SBIM - Senior Engineer

Construction Engineering - Senior Engineer;

Municipal Engineering - Senior Engineer;

Mechanical & Electrical Engineering - Senior Engineer;

Water Conservancy and Electric Power Engineering - Senior Engineer;

Road & Bridge Engineering – Senior Engineer;

Aerospace Engineering - Senior Engineer;

……

In other words, the star of aerospace engineering was lit up in this way.

Do the math, this is the seventh senior engineer level reached by Huake in 4 years.

After a moment's rest, he turned his gaze back to the screen in the center of the hall of the bunk hut.

The blue characters are pulsing, and new missions are appearing.

[Mission B002: Design and manufacture of the first rocket engine.] 】

Achievement Progress: 0 %.

Engine name: /.

Thrust: / ton.

Thermal power: /.

Time limit: within 8 months.

Reward for completing the mission: Earn 1,000 technical points.

……

Hua Kejing nodded silently after reading the task.

The engine is the heart of the rocket, and it determines the carrying capacity of spacecraft such as rockets into space.

And how big the carrying capacity of the rocket is, how big the space stage is.

Therefore, the development of high-performance high-thrust rocket engines is definitely the goal that the world's major space powers are striving for.

The strongest king of the current rocket is the Falcon Heavy.

But the strongest king of rocket engines is the new liquid rocket engine RD-171MV (timeline is 2021) of Russian production "Tsar Engine".

The RD-171MV engine has a thrust of more than 800 tons, which is more powerful than the F-1, the first stage engine installed on the "Saturn-5" heavy rocket, but it is smaller in size, and can be reused 10-15 times.

It is equipped with four combustion chambers and uses liquid oxygen kerosene. When the engine is running, the combustion chamber can produce 27 million kilowatts of thermal power, equivalent to the power of a large hydroelectric power plant.

In addition, the power of its engine turbopumps will reach 180,000 kilowatts, which is equivalent to the power of three nuclear power units of a large nuclear-powered icebreaker.

Realistically speaking, at present, there is no rocket engine in the world that can be compared with the RD-171MV, which makes Russia maintain a leading position in the world in the field of rocket engines.

It is conceivable that if the Russian "Yenisei" heavy launch vehicle is equipped with multiple RD-171MV engines at the same time, it will surpass the Falcon Heavy and become the new carrier rocket.

PS: The Yenisei heavy-lift launch vehicle for missions to the moon and even Mars is also under development, which may consist of six boosters equipped with RD-171 engines and a core stage with RD-180 engines. Currently, the United States is developing a heavy rocket, the SLS, and China is also developing the Long March 9 heavy rocket.

"It is indeed a solid and reliable wool goods!"

Huakejing is also full of respect for the RD-171MV engine.

And the best respect is to surpass her with all her strength!

Of course, Muyu Aerospace, as a new company with no hair, wants to manufacture its own rocket engine in just 8 months, which is definitely difficult.

Under normal circumstances, rocket engines are designed and manufactured on a year-by-year basis.

8 months, it's almost dying.

"If the time is up and the mission is not completed, you just wait."

These words are always in my ears.

This is Xiaole's urine, Hua Kejing has been forced by her to run like this for nearly five years.

But pressure and enthusiasm alone are not enough, whether it is to build rockets or engines, you have to build factories.

Li Chenjing has said again and again that he will personally lead the team of Yijing Construction to build the factory at the speed of light.

But it's not enough to have a factory building, so what about building a rocket production line?

This in itself is more difficult than building rockets, countless high-precision and sophisticated, mainly very expensive, and if you really want to do it, not only the capital investment is tight, but the time is also protracted.

Where can this be done in 8 months!!

Hua Kejing shook his head, and had to go in two steps, first dismantling the engine plan, building the necessary production line, and looking for a series of suppliers to produce and process parts on behalf of him, and integrating and packaging at the right time.

Of course, Hua Kejing also thought of another way, which is to use metal 3D printing equipment to print rocket engines.

In fact, this technology has been actively tried by two brothers in the United States, and has also received hundreds of millions of dollars in investment and signed a cooperation agreement with NASA.

Through metal 3D printing technology, structural integration components can be manufactured, which is very suitable for special-shaped components, complex structural parts, and special requirements parts that are not suitable for welding.

If additive manufacturing is applied to the manufacture of rocket components, it is possible to significantly reduce the number of rocket parts in the design, but also to significantly reduce the cost, quickly apply new designs and mass produce large engines.

Come to think of it, reducing the number of rocket parts from 100,000 to 1,000, and then drastically reducing labor time by orders of magnitude, would definitely have a profound impact on the rocket's delivery time, product iteration speed, and cost reduction.

But this will go back to the old problem, so that Muyu Aerospace to develop the corresponding metal 3D printer is not only costly, but also time-consuming.

And the foreign brother of Lao Mei will definitely not lend their core technology, Stargate 3D printer, to Muyu Aerospace for use.

Not to mention the engines they now print out – the Aeon 1 liquid oxygen methane rocket engine – less than one-tenth the thrust of the SpaceX Falcon 9's Merlin 1D engine.

Moreover, the metal materials printed by 3D cannot meet various strength requirements at present, especially the fibrous directional strength that forged materials have.

For example, in the combustion chamber of an engine, the 3D printing effect of turbopump blades is far less effective than casting and forging special alloys.

……

I would like to pay tribute to every friend who has been with me all the way, and thank you from the bottom of my heart for your support!
