The entire aircraft has been assembled and inspected on the ground. The robotic arm in mid-air is also loaded with inspection equipment to scan and model the aircraft's interior and exterior.
In the observation room outside the wind tunnel, Gu Qing saw the engineer wearing SR1 glasses and fine touch gloves to enlarge, enlarge, and then enlarge the scanned and projected aircraft model.
There are also AI prompts on the side.
[The fuselage modeling has been completed and the logic test has passed]
[The special metal device has been linked to the sensor, and the data complies with the standards]
[Body posture adjustment completed]
On-site manual inspection, machine inspection, AI modeling and reprocessing, and self-inspection of the aircraft's own system are also completed.
At this time, the staff and the robots in the wind tunnel also began to organize their tools and evacuate the core area of the wind tunnel in an orderly manner.
Under normal circumstances, wind tunnel testing is divided into six stages.
The data submission stage before manufacturing compliance inspection, the determination of manufacturing compliance inspection items and inspection plan stage, the intermediate manufacturing compliance inspection stage of test parts, the final manufacturing compliance inspection stage of test parts, the pre-test manufacturing compliance inspection and test witnessing stage, Post-test data submission stage.
It seems complicated, but in simple terms, it is necessary to collect model design information such as wind tunnel test digital model, model processing and inspection requirements, and model design report before the wind tunnel experiment. Provided to wind tunnel management.
After approval, the wind tunnel manager will also check these items. Although generally, the manager will not inspect all parts of the wind tunnel test model, but the manager will extract key components and some important parts. Parts are inspected.
After the wind tunnel manager has a full understanding of the aircraft digital model design, these parts for inspection must be marked to avoid subsequent inability to inspect.
After these inspections are passed, the wind tunnel management team will also exclude representatives from witnessing the test and key blowing trains to ensure that the test standards are met and that the test objects are the applied objects. At the same time, they will also check whether the test personnel are working in strict accordance with the test outline.
After a while, the wind tunnel management team had a comprehensive grasp of the aircraft's main manufacturers, model processing units, aircraft specific parameters and even manufacturing processes.
After all, the resources consumed to design and manufacture an aircraft are far less than the cost of designing and constructing a high-end wind tunnel. This can prevent malicious people from deliberately damaging the wind tunnel test building to the greatest extent.
But doing so also shows all the aircraft data to the wind tunnel manager.
Gu Qing has always controlled the research and development process of major projects in the aerospace department. Of course, the previous results that were trivial and could be made public can be solved using the wind tunnel provided by the Daxia official.
But now Jiuzhou Technology has changed from a small business that is harmless to humans and animals to an important force that all forces attach great importance to. Many experiments cannot be conducted in the officially provided testing sites.
Wind tunnels, which are crucial to the development of spacecraft, aircraft, automobiles and other projects, naturally must be controlled by oneself.
After all the preparations were completed, the aircraft, which gradually lit up the lights on the wind tunnel platform, began work.
Inside the wind tunnel, which had already returned to silence, there seemed to be a sound of birds chirping.
At this time, everyone in the observation room looked at Gu Qing in unison.
This young man, who was thirty years old, said loudly: "Let's start according to the established plan."
Luo Yongshan, the Zhuyue Starship project engineer standing by, heard these words and unconsciously took a deep breath.
If the fighter jet he designed fails in the wind tunnel test, it will not only be a major blow to him personally, but also a failure case with great impact on the entire project team.
The other staff in charge of the wind tunnel were also in a very solemn mood. After all, this experiment was the first official test of this wind tunnel. If something went wrong, it would not only delay the projects lined up behind, but also have to go in from the outside. Sorting through it not only consumes money, but also consumes people's patience.
Therefore, this time the fighter wind tunnel test can only succeed, not fail.
The whistling sound of wind gradually sounded in the wind tunnel.
From a design point of view, the wind tunnel is actually an alternative type of man-made tunnel, except that the length, height and internal air circulation system of this tunnel are all controlled by human machines.
The motor started to start, the wind speed gradually increased, and the fighter plane in the wind tunnel began to spread its wings like a bird about to take off.
[In the first stage, the system starts successfully. 】
[The second stage, preparation]
Such a string of characters was displayed on the right side of the big screen in front of Gu Qing, and then the pipes on both sides of the wind tunnel began to exhaust and pressurize. In the passage to the north, there was a large device that was absorbing gas like crazy, and in the passage to the south, there were also A large device is beginning to evacuate the interior to a vacuum state as much as possible.
The press, heating system and refrigeration system also work simultaneously.
[The second phase is ready and begins]
coax!
With a bang, a strong air flow suddenly erupted in the wind tunnel. The device in the north of the wind tunnel was a super high-pressure gas tank, while the device in the south on the other side was a vacuum tank. At the same time, the wind tunnel passage was heated and cooled. At two temperatures, as soon as the valve is opened, a huge pressure difference will instantly occur between the two gas tanks. The high-pressure gas will instantly spurt towards the vacuum end. Under the action of this gas movement, the speed of the air flow will increase by 5 times, reaching the supersonic speed standard.
The plane on the wind tunnel platform has already spread its wings and is flying high.
Under the impact of the huge airflow, this fighter plane is like a petrel fighting against the waves, with a proud and tough attitude, agile and stable.
As time passed slowly, the airflow in the wind tunnel gradually became slower, and then the fighter plane slowly landed.
[In the second stage, the system runs successfully. 】
[The third stage, preparation]
The high-speed standard is just the appetizer, the real meat and potatoes are just beginning now.
At this time, the little joy of having just succeeded twice was suppressed by everyone.
After high sound speed, there is hypersonic speed.
Normally, Mach 1 is equal to 1 times the speed of sound, which is also equal to 340 meters per second.
If the wind tunnel flow velocity is converted into Mach number, then 3-10 kilometers/second is equivalent to 30 times the speed of sound or Mach 30.
The most basic data standard for hypersonic weapons is that the speed exceeds Mach 5, so the development of hypersonic aircraft requires the support of hypersonic wind tunnels.
According to classification, aerospace aircraft can be divided into first-level and second-level. The first-level aerospace plane can derive hypersonic reconnaissance aircraft, suborbital bombers, hypersonic passenger aircraft and other aircraft; while the second-level aerospace plane can derive spacecraft such as orbital bombers and space carriers.
In order to carry out the third stage of work, the wind tunnel must have stronger wind power. When both pressure difference and temperature difference are used, Jiuzhou Technology engineers also designed a shock stage unit generated by the explosion.
The energy that bursts out instantly from the explosion is used in the wind tunnel. The combination of strong pressure, temperature difference, and pressure difference can produce supersonic airflow in an instant.
Originally, Gu Qing wanted to add an arc accelerating device, but the wind tunnel design team told Boss Gu a very regrettable message.
If an arc accelerating device is added, the completion time of the wind tunnel project will be postponed by about another year. If the two systems are not compatible, the time will be extended.
Scientific experiments are not just piles of wood. Materials and technologies can be piled on top of the project.
Experimental buildings such as large-scale wind tunnels not only require materials and technology, but also the unification of equipment and technology. Adding technology to other systems indiscriminately also requires setting aside more design resources, energy resources, and material resources.
After countless troubles, there are also the problems of care and maintenance.
Therefore, Jiuzhou Technology’s first super-large wind tunnel still relies on explosion, pressure difference, and temperature difference to complete the final high-intensity wind speed test.
The heating system began to seal hydrogen and oxygen into large tanks made of special materials, and the vacuum tanks and pressure tanks that had worked once before also started working for the second time.
As time passed, the air in the wind tunnel began to flow slowly.
The unnamed fighter plane gradually had red lines of flames appearing on its wings.
The missile fixing devices under the cabin and wings also began emergency self-inspection and strengthening, and some of the unstable devices on the outer branches were also retracted into the cabin.
[The third phase is ready and begins]
three
two
one!
There was no sound, but everyone felt a vibration that shook their hearts. Even some trees on the mountains began to shake the fragile new branches that grew this spring and summer.
Gu Qing and others saw the surge of air flow like a mushroom explosion through the footage taken from a fixed camera position.
Even the most arrogant person would not dare to enter this huge and rapid airflow, because the pressure difference and the explosion shock wave will instantly break through the fragile human body and tear it into real pieces.
Through combustion, an explosion will eventually occur. The powerful air flow, under the influence of temperature difference and air pressure difference, is countless times more powerful than Blue Fat Cat's plus air cannon.
And that fighter plane, bombarded by hypersonic winds, not only did not disintegrate, but also did not suddenly change its attitude and was forced to collide.
It is like a mythical bird, still so brave, even singing generously in the face of a hurricane!
And while the fighter plane maintained its posture——
"Mach 2, Mach 3, Mach 4?! Mach 5?!!"
"Hold the grass?!"
A young wind tunnel worker suddenly made a sound.
If it were during normal working hours, his frivolous and rude behavior would be quickly stopped by people's eyes.
But today, even those engineers, no matter how mature and steady they usually are, were already in a state of panic and could not express their excitement in words.
Even Gu Qing was slightly distracted when he saw this scene.
What is Mach 5?
The MiG-25, which used to have a red sickle, once demonstrated a terrifying speed of Mach 3.2, which means that this fighter can easily evade Sidewinder missiles with speeds up to Mach 2.7.
It's just that the current fourth-and-a-half- and fifth-generation aircraft have abandoned the "stupid method" of simply relying on speed to avoid missiles, and instead use electronic attacks and stealth capabilities to improve the survival rate of fighter aircraft.
Currently the most popular J20 in Daxia, the official maximum flight speed is Mach 2.5, which is 2.5 times the speed of sound.
According to Daxia's long-term "virtual standard" strategy, the J20's maximum flight speed may reach Mach 2.8, but it will never exceed Mach 3.
And this fighter jet, which can obviously carry people, can reach a maximum flight speed of Mach 5.
what does that mean?
Many staff members even felt a sense of panic after being shocked.
Such a terrifying weapon actually appeared?
And it is true in their testimony.
Some people even looked at Luo Yongshan, the chief engineer of the Moon Starship project, because these people knew that the main designer of the fighter jet was this middle-aged man who seemed harmless to humans and animals.
Luo Yongshan seemed not to notice these glances.
He took out his tablet, connected it to the system in the observation room, and checked the data with great proficiency.
Gu Qing stood aside, still silent, waiting for him.
Zhao Jianming, the person in charge of the wind tunnel, also checked the data with a solemn expression to see if there were any other problems.
The person in charge of the relevant links also returned to work after being distracted for a moment.
No one dares to be negligent, and no one dares to declare the experiment a success without doing any checks.
They need to be responsible for the experiment and every scientist and engineer.
The intelligent AI program Tiangong has already activated supercomputing and a fixed share of cloud computing resources at this time, and based on the data currently available, it has created a feudal system in the experimental server of Lingjing Ecology and conducted tens of thousands of experimental deductions.
It is foreseeable that as more experiments are conducted in this wind tunnel experimental building, the data from this experimental server will become more and more "real".
Five minutes passed, but Luo Yongshan, Zhao Jianming and others still didn't say a word.
And Gu Qing just waited patiently, without urging or disturbing.
When half an hour passed, the intelligent AI program Tiangongdu had given feedback data of the real wind tunnel test. Zhao Jianming and Luo Yongshan said one after another: "The data is accurate and the experiment was successful."
Bang bang bang! ! !
Applause and cheers resounded all around at this moment. R&D personnel, engineers and scientists hugged each other, their faces full of excitement.
However, no one hugged Gu Qing at this time, because there were already two security personnel standing silently beside him.
A gentleman does not build a dangerous wall, and Gu Qing will not give any dangerous person a chance to contact him.
When everyone's extremely excited mood began to cool down a little, and when the grinning corners of Luo Yongshan and others gradually stabilized, Gu Qing smiled and suddenly said: "Congratulations everyone, we have finally taken the first step on a journey of thousands of miles. .
This fighter plane should also have its own name. "
Before the experiment is successful, each aircraft company only has a code name within the project, which may be a number, a letter, or even some inexplicable symbols.
But if the experiment is successful, this fighter will have a name unique to it.
