God of Rebirth Trader

The Reborn God-Level Trader Text Volume Chapter 424 The latest website of the Sky Verification Machine: Zhao Gong finally found a chance to talk to Nikolai for a while while he was drinking water. As they were talking

Nicola's eyes never left the screen.

He mainly came to inquire about the latest research progress of several material formulas. At the same time, he also asked the materials department to provide detailed data on some new materials to facilitate the manufacturing department to formulate the best processing and manufacturing plan based on relevant data.

For the outstanding achievements of the materials department, several other research departments cheered, but only the manufacturing department felt a headache.

With the emergence of various new materials, the strength, corrosion resistance, high temperature resistance, and high pressure resistance of these materials have been repeatedly updated, surpassing the old materials in one fell swoop.

This has brought big problems to the manufacturing department.

Some conventional processing technologies can no longer be used on these new materials.

Some materials are extremely hard and difficult to process even with new alloy tools.

Some materials are resistant to high temperatures. Once synthesized, it will be very difficult to change the shape. The only option is to use powerful lasers and polish them bit by bit.

Therefore, in order to produce the samples required by various research departments, the manufacturing department also conducts research and familiarity with the characteristics of new materials day and night. Only by understanding their specific characteristics can we adopt various new manufacturing processes in a targeted manner to conduct their research.

processing.

This requires detailed material data as the basis for their analysis.

The scene urged Nikola to upload the relevant data to the database of the manufacturing department, and then Engineer Zhao left the materials department.

He came to the power department and handed them the small rocket engine samples they needed. After signing the receipt, he did not leave immediately, but started discussing with them.

The projects researched by the power department include relatively common ramjet engines, rocket engines, electromagnetic propulsion systems, etc., as well as some advanced theoretical research projects.

Such as: laser kinetic energy engine, superconducting generator, electromagnetic funnel ion jet propulsion system, etc.

Some theoretical research has begun to take shape, but experimental conditions are lacking.

Fortunately, the emergence of the Tiandao system gave them a platform that combines theory with practice to conduct in-depth research.

Gong Zhao was discussing with several researchers and was surprised to see Wang Fangjun walking in.

Wang Fangjun's official position is the security director of the base, in charge of various defense matters, and he is quite busy. He rarely goes underground. What's going on here now?

Wang Fangjun saw Gong Zhao at a glance and greeted him with a smile: "Gong Zhao, I finally found you. They said you went to the materials department. I ran to the materials department, but they said you had left."

"Haha, I will send them samples and stop by the materials department to learn about the progress of the latest formula." Zhao Gong said with a smile.

Wang Fangjun turned around and looked around and asked, "Why isn't Chief Engineer Yan here?"

Chief Engineer Yan is the head of the power department and a rare elder in the base. He is over 70 years old this year.

A researcher from the power department office said: "Old Yan has gone to the scramjet engine project team. Today we have to verify a new material. He has always been very concerned about it and went there early."

The researcher looked at his watch and then said: "The experiment has been going on for several hours. According to the time, it should be almost over. Director Wang, why don't you wait any longer?"

"No wait, let's go over!"

Wang Fangjun nodded to Zhao Gong, and the two went out side by side.

In Zhao Gong's mind, he thought that he came to see him and Mr. Yan specially, guessed what he was thinking, and asked in a low voice in the corridor: "Are you ready to carry out engine trial production?"

"Yes, word came from the company headquarters that rocket launch technology is making rapid progress, but after repeated discussions, the academic committee felt that with our current technical level, we can completely abandon the tradition and use rockets to launch satellites, and directly launch the spacecraft in one step.

The development of the spacecraft.”

Wang Fangjun recognized his judgment.

Zhao Gong frowned and said with some worry: "Is it too hasty? The scramjet engine has only made great progress this year, and this is still the result of simulation verification. Even the engine design has not yet been completed.

It’s not completely finalized yet, we have to make a sample, and it can’t be completed overnight.”

Wang Fangjun admitted that what he said made sense, but he still said: "The academic committee has no choice but to do so. The core of the aerospace aircraft lies in the combined scramjet engine, but the lower limit of the starting speed of the scramjet engine is Mach 5."

"We cannot obtain experimental data on the ground, let alone improve it."

"In a small place like The Gambia, the aircraft flew out of the airspace as soon as the afterburner was turned on. There was not even a basic environment for testing. Besides, we did not dare to openly test the scramjet engine under the watchful eyes of other countries."

"Now that we have the Tiandao system, I heard that environmental system simulation uses a large amount of aerospace data from the final assembly department and the lunar landing project team for verification, ensuring that the simulation system is as close to reality as possible, which is of great help to our research."

"However, after all, this cannot guarantee 100% authenticity. A small mistake in the research will cause irreparable losses in actual operation. If there is an opportunity to conduct actual verification, of course it will be useful for us to collect data and improve engine design.

They are all of great help.”

Engine research has always been a big difficulty.

Because the flame combustion in the combustion chamber is difficult to simulate with computers, people can only use more practical tests and use wind tunnels to verify the design effect with the help of computers.

The original design process of the J-10 was developed using a wind tunnel and Infinity Company's supercomputer.

Moreover, the tens of trillions of supercomputers at that time were mainly used for research on engine materials, and it was not possible to fully use computers to verify designs from beginning to end.

Just this investment is unbearable for the average country.

The scramjet engine design goes beyond the difficulties of ordinary aerospace engines.

The ramjet engine is a special engine widely used in missiles and supersonic fighters. Its design idea is derived from the "turbojet", which eliminates the complex turbofan air intake device of the turbojet. The structure is more compact, simple, and easy to manufacture.

But since the ramjet engine does not have a turbofan air intake device, it needs an initial speed to make the engine run.

The minimum condition for starting a ramjet engine is not less than Mach 0.5.

The scramjet engine is actually a special engine specially used for low-Earth orbit and cruise fighters. Its starting conditions are more stringent. The minimum starting speed must not be lower than Mach 4~5!

Such high requirements make it impossible for the scramjet engine to be tested on the ground. It must be installed on a verification machine and tested in the sky!

Who can guarantee that the scramjet engine they designed will have absolutely no problems?

In the initial design of products, there will inevitably be design errors of one kind or another. Each error will bring catastrophic results such as the crash of the verification machine and the explosion of the engine.

Even if a super-rich country like the United States does such research and development, they would not burn money like this unless they have no choice!

Talk about it.

The United States has been developing scramjet engines intermittently as the international situation changes.

The Soviet Union had not yet disintegrated in the last century, and when it was being developed, the United States immediately launched its research and development institutions and spared no effort in research and development. However, as soon as the international situation eased, they immediately stopped research on scramjet engines on the pretext of insufficient funds.

Therefore, even though they have been working on it for decades, they have built a lot of demonstrative engines and conducted hundreds of flight tests.

However, the United States has never had a systematic research idea, and it is intermittent. It often changes the research direction based on technological progress and puts forward different design requirements, causing R&D companies to suffer.

In the initial research at the African base, a lot of theoretical research was conducted. Later, with the cooperation of photonic computers, the research progress was much faster.

Researchers in the power department used as many simulation calculations as possible to determine the final actual direction.

Now we are adopting the design idea of ​​variable geometry air inlet channel to fully tackle the problem.

In recent years, although they have not launched a physical product, the technical obstacles related to this have been solved to some extent, and enough key technologies have been accumulated.

The Tiandao system, this simulated world, allows the research team to put aside algorithmic problems and directly assign relevant data to the engine model to build a nearly real engine.

Under different conditions of aerodynamic environment, the variables of the engine are clearly placed in front of the researchers.

The scramjet engine team, which had been stagnant for a long time, suddenly regained its vitality. Nearly ten simulated wind tests every day allowed them to obtain a large number of precious technical parameters.

The development work of the engine is advancing rapidly while problems are discovered and continuously improved.

All that's left now is an actual flight test!

"Since that's the case, I have no objection." Zhao Gong was silent for a moment, and then said: "However, I think it is not appropriate to conduct full-scale verification. We can first make a scaled-down experimental engine, which is enough to verify the relevant data.

.”

"This can also save a lot of money. In addition, we are still confident that we can complete the small-size verification engine, but if it comes to full-size, to be honest, it will be very difficult for us."

"Of course!" Wang Fangjun said with a smile, "Mr. Chen means that one or two satellites will still be launched using rockets. After all, we can't use a super large aerospace aircraft with a length of more than a hundred meters to launch only one or two satellites."

A satellite weighing more than 100 kilograms, it’s such a waste.”

While talking, they came to the laboratory of the scramjet engine project team.
