Chapter 739

Inside a noisy and scattered liquid oxygen kerosene engine workshop.

Director Bi and his assistant, who were frowning, hurriedly walked in.

Not long ago.

Director Bi received a call from Director Nie of the liquid oxygen kerosene engine workshop, saying that Professor Gu had something very important to look for him.

Hear the eagerness in Director Nie's words.

Director Bi thought that Gu Lu was causing some trouble.

So he couldn't even bother to open the meeting, so he hurried to come.

That's right!

When I received a call from Director Nie just now, Director Bi was holding a meeting at the core level.

And the content of the meeting.

It is to discuss how to solve a series of problems encountered in the development of the Long March 9 launch vehicle.

Because.

At the current pace.

Basically, it is impossible to get this new Long March 9 launch vehicle out before 2024.

…………

Gu Li's workstation is in a corner of the workshop.

When Director Bi and his assistant arrived.

There were already a few people scattered around Gu Lu.

These people are all technical research and development personnel of the liquid oxygen kerosene engine of the base, and belong to the backbone of the liquid oxygen kerosene engine workshop.

But now.

These people were all attracted by the beautiful machine beside Gu Lu.

It was a huge engine.

Although the engine is made up of a patchwork of discarded parts, it still can't hide its structural beauty.

The engineers gathered around looked at it and looked at it with a dizzying color.

Of course, they are knowledgeable.

The engine in front of Gu Lu.

Let's not talk about anything else.

At least in terms of construction, it is perfect.

And at this time.

Director Bi also stopped and looked up at the huge engine.

This engine is a model larger than the usual engine.

But since Director Bi can be the leader of this base, of course, he has a deep understanding of the liquid oxygen kerosene engine.

In Director Bi's opinion.

At least this engine is not played by Gu Lu.

Because in terms of the connection and composition between various parts, it is in line with the principle of liquid oxygen kerosene engine.

But what exactly is the situation.

He also needs to see the schematic diagram of the internal structure of this engine or its actual operation before he can make a conclusion.

But, one thing is for sure.

That's this Professor Gu, there really is, something!

…………

Gu Lu helped the helmet, screwed the last screw with a screwdriver, turned around and wiped the sweat on his forehead.

"Director Bi, you're here!"

Seeing Director Bi standing on the side, Gu Lu nodded and said hello.

Director Bi didn't have much energy to greet Gu Lu, but walked directly in front of Gu Lu, pointed to the liquid oxygen kerosene engine that was lifted by a crane and asked.

"Professor Gu, did you build this engine?" in his tone, Director Bi was a little surprised.

Gu Lu shrugged his shoulders and didn't deny it, "That's right, I made it." ”

Director Bi raised his eyebrows, "Alone?"

Gu Lu took off the rubber gloves on his hand and threw them on the table beside him, "One person." ”

"Can you run it and let me see?" Director Bi said with a deep curiosity.

"Yes!" Gu Lu agreed, "However, I need some fuel." ”

Director Bi gestured to Director Nie, who was standing on his left, "Get some fuel for Professor Gu." ”

Since Director Bi has spoken, Director Nie will of course do so.

He rubbed his hands together and looked at Gu Lu with a smile, "Professor Gu, how much fuel do you need?"

Gu Lu made a rough estimate in his mind, and reported a number, "About five hundred catties." ”

According to the design draft.

The liquid oxygen kerosene engine can hold about 2.5 tons of fuel.

And if you want to conduct a simulation of engine operation, you need at least 500 pounds of fuel, otherwise it makes no sense at all.

Director Bi directly beckoned to Director Nie, "Old Nie, just let someone pull a thousand catties of fuel." ”

Director Bi is not a person who is stingy with those 500 catties of fuel.

500 catties of fuel is only a drop in the bucket compared to the expenditure of hundreds of millions of R&D funds in the entire rocket R&D base that year.

Compared to the 500 pounds of fuel.

Director Bi is even more curious about the effect of the liquid oxygen kerosene engine designed, developed and manufactured by Gu Lu alone.

Right now.

Director Bi has to admit one thing.

Professor Gu, the technical advisor sent by the headquarters, is indeed something, and he is not the gold-plated boy he thought before.

But......

Even if Gu Lu has the ability.

Director Bi also didn't believe that Gu Lu could design a liquid oxygen kerosene engine that met the requirements of the launch vehicle by himself.

This is clearly unrealistic.

So.

For the slightly large liquid oxygen kerosene engine designed by Gu Lu in front of him.

Director Bi expects that there is.

But not very high.

In Director Bi's concept.

Gu Lu's engine, at most, is a small improvement to the data of the original model.

However, this is already very okay for a young man like Gu Lu who is less than thirty years old.

This proves that Gu Lu is a talented technical talent.

Wait until this is over.

It is possible to let Gu Lu go to a technical leadership position and be responsible for tackling a technical problem.

Director Bi was silently thinking in his heart.

…………

Soon.

A thousand pounds of fuel were delivered.

Workers then fill the engine with this fuel.

Then.

Forklifts drive in.

The filled liquid oxygen and kerosene engine is transported directly to the vacuum chamber.

The vacuum chamber is equivalent to a simulation of the outer space environment.

Launch vehicles need to be lifted off.

The engine, which is one of the components of the launch vehicle, must also meet some data conditions in a vacuum environment.

Specifically for the Long March 9.

A total of six liquid oxygen kerosene engines were required.

Then you can count the weight of the rocket body, fuel.

In order to achieve the earth-moon transfer orbit, if the carrying capacity of the rocket reaches the figure of 50 tons, the vacuum thrust of the liquid oxygen kerosene engine is not less than 7000KN, and the vacuum specific impulse is not less than 300S.

Vacuum specific impulse refers to the impulse produced by a unit mass of propellant in a vacuum environment.

Presently.

The engine that can make the vacuum thrust exceed 7000KN and the vacuum specific impulse exceeds 300S seems to be the only Saturn series rocket on the side of the United States.

And for Huaguo.

With the hard work of many scientific researchers.

Nowadays, these two figures are still around 5000KN and 250S.

The gap is not very big though.

But there is still a long way to go.

And this is not a small distance.

But I don't know how long it will take and how much money it will take to make up for it.
