Domestic car manufacturing is weak, what does it have to do with our land tanks?

Hongqi is going to apply for the qualification to build a rocket launch platform and send satellites into space.

This seems incredible to ordinary people.

Even in the eyes of aerospace people, it is very explosive!!

This thing, you can’t apply for it whenever you want, it’s not like you can just register a company.

To get national approval, you must first prove that you have the ability, right?

In Gong Nanjiang’s view, Hongqi is competing with Tesla, so it is better to cooperate with China’s existing aerospace companies to register a rocket company.

After all.

Not everyone is Musk. Even Musk almost bankrupted himself in order to build rockets.

So he has doubts.

Where does Hongqi get the confidence?

If you can’t even build the most basic rocket engine, then you don’t have the qualifications to get approval…

Rocket engine engines are not easy to deal with.

“In fact, if you want to achieve vehicle-to-satellite interconnection, you can also consider China’s ready-made commercial satellites.……”

Gong Nanjiang hadn’t finished speaking yet.

Suddenly,

Ding Ke came in in a hurry!

His face was very panicked, which was not common in the Rocket Assembly Technology Department.

Even when the rocket exploded during launch, Ding Ke had never been so panicked.

“Dean, I just found a technical discussion form in the Red Flag application documents. I printed it out for you.……”

“Hmm? How come…”

Gong Nanjiang took the report subconsciously and glanced at it.

The first page of this technical discussion report was the rocket engine technical discussion.

Gong Nanjiang saw the first line of words——

【Discussion on concentrated liquid hydrogen engine technology…]

Hmm?

Hongqi has its own rocket engine technology?

Gong Nanjiang was stunned for a moment.

But soon, he found something wrong.

Very wrong!!!

Liquid hydrogen rocket engine?

Wait!

Hongqi has developed its own liquid hydrogen engine technology?

How is this possible?

Hongqi is an automobile company, how could it possibly come up with this thing!!

As we all know, the rocket propellants commonly used in aviation are liquid oxygen and rocket-grade kerosene, that is,——

【Liquid oxygen-kerosene rocket engine engine]

The launch vehicle using the”liquid oxygen-kerosene rocket engine” is characterized by high energy density, large overall thrust, and high thrust-to-weight ratio.

The”Falcon 9″ built by Musk uses the Merlin engine, which is completely developed and manufactured internally by SpaceX, and the propellants are liquid oxygen and rocket-grade kerosene.

A single Merlin engine has a sea level thrust of 756 kilonewtons, an atmospheric thrust of 825 kilonewtons, and a thrust-to-weight ratio of more than 150.

What is this concept?

From the perspective of the aerospace field, the Merlin engine is one of the most efficient rocket booster engines in the world.

Using liquid oxygen and aviation kerosene as propellant fuel, the power advantage is great.

However, various aerospace powers are currently secretly working on the research of [liquid hydrogen rocket engines], and believe that [liquid hydrogen rocket engines] are the general direction of future aerospace technology!

The reason is very simple.

Using liquid oxygen and aviation kerosene as rocket engine propellants, although the thrust is large and the thrust-to-weight ratio is high, but because kerosene is a room temperature fuel, it is extremely inconvenient to store it together with cryogenic liquids such as liquid oxygen. A special thermal insulation layer is required, which increases the manufacturing cost and weight of the rocket.

Secondly, aerospace kerosene has a high density and contains a large amount of carbon. When it burns, it will produce carbon deposits in the engine. The higher the carbon content of the kerosene, the more serious this phenomenon will be.

After each flight, SpaceX employees must carefully clean the carbon deposits in the Merlin engine. The process is quite cumbersome, and the carbon deposit problem also has certain problems, causing the injector to cause the injector to become clogged. Of course, another reason is that it is expensive. The aerospace kerosene and liquid oxygen fuel that need to be burned in a heavy-duty transport rocket launch costs hundreds of thousands of dollars. In comparison.

【Liquid hydrogen rocket engine: Using liquid hydrogen as a propellant is recognized as the best chemical propellant at present. It burns more fully, is pollution-free after combustion, and can be reused.

Of course, there are still some technical problems to be solved, such as the low temperature problem of liquid hydrogen itself, hydrogen liquefaction and storage, explosion hazards, etc…. and the problem of weak total thrust caused by the difference in energy density. Liquid oxygen-kerosene engines can achieve a thrust of 700 tons, while liquid hydrogen and liquid oxygen can only achieve a thrust of 300 tons.

In general, although China has the technology of liquid hydrogen rocket engines, the main heavy-duty launch vehicles are still based on liquid oxygen aviation kerosene, and the second stage of the booster core uses solid engines and liquid hydrogen engines as auxiliary.

When seeing the words [liquid hydrogen rocket engine], Gong Nanjiang was a little bit unbelievable at the first time.

I didn’t expect the starting point of Hongqi to be so high.

Out of the habit of aviation researchers, he immediately looked down.

Then he saw a huge simple design drawing of the”regenerative cycle engine thrust chamber” below.

It is marked with an estimated thrust data of up to – more than 5,000 tons!!

See this number. (To read the exciting novels, go to Flylu Novel Network!)

Gong Nanjiang immediately took a breath of cold air!!

This data is very exaggerated.

It has reached the top level of the world’s super-heavy rockets.

And the Red Flag actually relies on liquid hydrogen engines to achieve this.……[]

Continue to scroll down.

Gong Nanjiang saw another line of technology

【Super-tamed rocket recovery device】

“Using a small rocket booster launched from the ground for a second time, combined with an AI system and a heavy rocket that landed, to achieve the recovery and reuse of a heavy launch vehicle? ?”

Gong Nanjiang’s eyes widened for the first time!

Not only does Hongqi have to use a liquid hydrogen engine to drive a heavy rocket, it also has to recover the first-stage rocket!

This is a difficult problem that the entire aerospace department of China has been working on!

Next.

A series of aerospace technologies and satellite technologies are densely packed on many subsequent pages.

【Source Phased Array Antenna Technology】、【Ultra-high-speed intersatellite laser communication technology】、【Strong Magnetic Ion Thruster Technology】………….0 0

And the most important [Beidou Starlink Project]!!!

It was like a product sales list, laid out in front of us.

Although the specific core principles were not given, the explanation of some principles and parameter introductions undoubtedly proved the reliability of this”technical discussion”!!

Gong Nanjiang couldn’t take his eyes off it.

He was completely attracted.

This is a grand blueprint!!

At this time.

Ding Ke was very nervous, his throat was dry:

“Dean, look…”

Needless to say,

I know what this means.

If it can really be realized, it will make China’s aerospace technology a leader.

At this time,

Lu Yan over there also spoke.

“Leader, I have sent the relevant technical discussion to the application form. Why don’t you take a look at it? After reading it, we will definitely accept the guidance.”

Lu Yan was a little restrained.

To be honest, he had always been in contact with people from the military before.

He had not had much contact with the big leaders of the aerospace industry.

What’s more, he was the top leader.

His status was equivalent to the level of the general manager of the entire military equipment. With the superiority of our country’s aerospace department, it might even be higher.

Gong Nanjiang’s brain buzzed when he heard this. After so many years of calmness. He almost lost his temper!

After reading this technical discussion, he has completely changed his mind.

He has an incredible understanding of the Hongqi company.

Guidance?

They can’t achieve any of these things at present.

Why don’t you come and guide our First Academy of Aerospace?

…Man….

I’m a sabmado
