Chapter 423 Aerospace Verification Machine

Mr. Zhao managed to find a chance to talk with Nicholas for a while while they were drinking water. During their conversation, Nicholas never took his eyes off the screen.

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

Several other research departments cheered for the outstanding achievements of the material department, 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 also been updated again and again, surpassing the old materials in one fell swoop.

This creates a big problem for the manufacturing sector.

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

Some materials are extremely hard, even with new alloy tools, it is difficult to process.

And some materials are resistant to high temperature. Once synthesized, it will be very difficult to change the shape. We can only use a powerful laser and polish it a little bit.

Therefore, in order to manufacture the samples required by various research departments, the manufacturing department also conducts research on the characteristics of new materials day and night to familiarize themselves with the characteristics of new materials. processing.

This necessitates 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 Zhao Gongcai left the material department.

He came to the power department and handed them the small rocket engine samples they needed. After signing the receipt, he didn't leave immediately, but discussed with them.

The projects studied by the power department include not only relatively common ramjet engines, rocket engines, electromagnetic propulsion systems, etc., but also 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 lacks experimental conditions.

Fortunately, the emergence of the Heavenly Dao system gave them a platform for combining theory with practice, allowing them to conduct in-depth research.

Zhao Gong 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. He is in charge of various defense matters, and he is busy with business. He rarely comes underground. Now that he is here, what's the matter?

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, but I ran to the materials department, but they said you had left."

"Hehe, I'll send them samples and stop by the material department to learn about the progress of the latest formula." Zhao Gong said with a smile.

Wang Fangjun turned his head to look around, and asked, "Why isn't Chief Engineer Yan here?"

Mr. Yan is the person in charge of the power department, a rare elder in the base, and he is over 70 years old this year.

A researcher from the office of the power department said: "Old Yan has gone to the scramjet engine project team. Today, he is going to verify a new material. He has been very concerned about it, so he went early."

The researcher looked at his watch and said, "The experiment has been going on for several hours. According to the time, it should be almost over. Director Wang, do you want to wait?"

"Don't wait, let's go!"

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

In Zhao Gong's mind, he thought that he came to find himself and Mr. Yan specially, and guessed his thoughts. In the aisle, he asked in a low voice: "Are you ready to start the trial production of the engine?"

"Yes, word came from the company's headquarters that rocket launch technology is progressing rapidly, but after repeated discussions, the academic committee felt that with our current level of technology, we can completely abandon the tradition and use rockets to launch satellites. development of the space plane."

Wang Fangjun approved his judgment.

Zhao Gong frowned, and said worriedly: "Is it too hasty? The scramjet engine has made relatively great progress only in this year, and this is still the effect of simulation verification. It is not fully finalized, and we have to make samples, let alone it can be completed overnight.”

Wang Fangjun admitted that what he said was very reasonable, but he still said: "The academic committee is also forced to do so. The core of the aerospace aircraft lies in the combined scramjet engine, but the lower limit of the start-up speed of the scramjet engine is Mach [-]."

"We can't get experimental data on the ground, let alone improve it."

"In the small place of Gambia, the plane flew out of the airspace as soon as the afterburner was turned on. There is no basic environment for the test. Besides, we dare not openly test the scramjet under the watchful eyes of other countries."

"Now that we have the Tiandao system, I heard that the simulation of the environmental system uses a large amount of aerospace data from the final assembly department and the moon 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 a chance to conduct actual verification, of course, it is important for us to collect data and improve engine design. It's been a huge help."

Engine research has always been a big difficulty.

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

The initial design process of the J-[-] was developed using a wind tunnel and supercomputers from Infinity Corporation.

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 do design verification from beginning to end.

Just this investment is unbearable for ordinary countries.

The design of the scramjet engine is 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 cancels the complicated turbofan intake device of the turbojet, and has a more compact, simple and easy-to-manufacture structure.

But the ramjet engine, since there is no turbofan intake device, it needs an initial velocity to make the engine run.

The minimum condition for the ramjet to start is not to be lower than Mach 0.5.

The scramjet engine is actually a special engine specially used for low-earth orbit and cruising fighter jets. Its starting conditions are more stringent, and the minimum starting speed must not be lower than Mach 4~5!

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

Who can guarantee that the scramjet engine designed by oneself will have absolutely no problems?
In the initial design of products, there will inevitably be design errors of one kind or another. Every mistake will bring catastrophic results such as the crash of the verification machine and the explosion of the engine.

This kind of research and development, even a super-rich country like the United States, is not a last resort, and they will not burn such money!
speak up.

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

The Soviet Union had not disintegrated in the last century, and when it was developing, the United States immediately launched its research and development institutions and spared no expense in the research and development. However, as soon as the international situation eased, they immediately stopped the scramjet research work under the pretext of insufficient funds.

Therefore, even though they have been working on it for decades, a large number of verification engines have been built, and hundreds of flight tests have been carried out successively.

However, the United States has never had a systematic research idea, and it is intermittent, and often changes the research direction from technological progress, and puts forward different design requirements, causing the research and development company to suffer.

In the initial research of the African base, a lot of theoretical research was carried out, and with the cooperation of photonic computers, the research progress was much faster.

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

Now it is adopting the design idea of ​​variable geometry air inlet channel to make every effort to tackle the problem.

In recent years, although they have not launched a real product, the technical obstacles related to this have been solved in sevens and eighties, and enough critical technologies have been accumulated.

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

Under the aerodynamic environment under different conditions, 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 times of simulated wind tests every day allowed them to obtain a large number of precious technical parameters.

The research and development of the engine is advancing rapidly while discovering problems and making continuous improvements.

All that is left now is an actual flight test!
"Since this is the case, I have no objection." Zhao Gong was silent for a while, and then said: "However, I think it is not appropriate to carry out full-scale verification. You can first make a scaled-down test engine, which is enough to verify the relevant data. .”

"This can also save a lot of money. In addition, we are still sure to complete the small-scale verification engine, but if we come to the full-scale, to be honest, we will be very difficult."

"Of course!" Wang Fangjun said with a smile, "President Chen means that one or two satellites should still be launched by rockets. A satellite weighing more than 100 kilograms is too wasteful."

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