Chapter 1347 Fighter

The whole aircraft was assembled and the ground inspection was completed. The mechanical arm in the air was also loaded with testing equipment to scan and model the inside and outside of the aircraft.

In the observation room outside the wind tunnel, Gu Qing saw the engineer wearing SR1 glasses and fine touch gloves to enlarge the scanned and projected aircraft model.

And there was an AI prompt on the side.

[The fuselage modeling has been completed and the logic test has passed]

[Special metal devices have been connected to the sensor and the data meets the standard]

[Fuselage posture adjustment is completed]

On-site manual inspection, machine inspection, AI modeling and reprocessing, and the aircraft's own system is also self-checked.

At this time, the staff and 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, the wind tunnel test is divided into six stages.

The stage of submitting materials before the manufacturing compliance inspection, the stage of determining the manufacturing compliance inspection items and inspection plans, the stage of intermediate manufacturing compliance inspection of test pieces, the stage of final manufacturing compliance inspection of test pieces, the stage of manufacturing compliance inspection and test witnessing before the test, and the stage of submitting materials after the test.

It seems complicated, but in simple terms, it is to provide the wind tunnel management with model design information such as wind tunnel test digital model, model processing and inspection requirements and model design report before the wind tunnel test.

After approval, the wind tunnel management will also check these items. Although in general, the management will not check all parts of the wind tunnel test model, the management will extract key parts and some important parts for inspection.

After the wind tunnel management fully understands the aircraft digital model design, it will also mark the parts to be inspected to avoid the situation where subsequent inspections cannot be carried out.

After these inspections are passed, the wind tunnel management will also exclude representatives from witnessing the test and key wind blowing trips to ensure that the test standards are met and the test objects are the applied objects. At the same time, it is also necessary to check whether the test personnel are working strictly in accordance with the test outline.

After all, the wind tunnel management has a comprehensive grasp of the main manufacturers, model processing units, specific parameters of the aircraft and even the manufacturing process of the aircraft.

After all, the resources consumed in designing and manufacturing an aircraft are far less than the design and construction costs of advanced wind tunnels. Doing so can avoid malicious people from deliberately destroying wind tunnel test buildings to the greatest extent.

However, doing so also shows all the aircraft data to the wind tunnel management.

Gu Qing has been controlling the development process of major projects in the aerospace department. The previous small-scale and public achievements can of course be solved with the wind tunnel provided by Daxia.

But now Jiuzhou Technology has changed from a harmless small enterprise to an important force that all parties attach great importance to, and many experiments cannot be carried out in the test sites provided by the official.

The wind tunnel, which is crucial to the development of spacecraft, aircraft, automobiles and other projects, must naturally be controlled in one's own hands.

When all the preparations were completed, the plane that gradually lit up the lights on the wind tunnel platform began to work.

There seemed to be a sound of birds chirping in the wind tunnel that had returned to silence.

At this time, everyone in the observation room looked at Gu Qing at the same time.

The young man, who was thirty years old, said loudly: "Let's start according to the established plan."

Luo Yongshan, an engineer of the Zhuyue Starship project, heard this and began to take a deep breath unconsciously.

If the fighter plane he designed failed in the wind tunnel test, it would not only be a major blow to him personally, but also a failure case with great influence on the entire project team.

The other staff members in charge of the wind tunnel were also in a very solemn mood. After all, this experiment was the first formal test of this wind tunnel. If there was a problem, it would not only delay the projects in the queue, but also have to be sorted out from the outside to the inside, which would not only cost money but also consume people's patience.

Therefore, this fighter plane wind tunnel test can only succeed, not fail.

The whirring sound of the wind gradually sounded in the wind tunnel.

From the design point of view, the wind tunnel is actually an alternative artificial tunnel, but the length, height and internal air circulation system of this tunnel are all controlled by human machines.

The motor started, 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 started successfully. 】

[Phase 2, preparation]

The right side of the big screen in front of Gu Qing showed such a string of characters, and then the pipes on both sides of the wind tunnel began to exhaust and pressurize. In the northern channel, a large device was madly absorbing gas, and in the southern channel, there was also a large device that was evacuating the interior to a vacuum state as much as possible.

The press, heating system and refrigeration system were also working synchronously.

[Phase 2 is ready, start]

Boom!

With a loud bang, a strong air flow suddenly broke out in the wind tunnel. The device in the north of the wind tunnel was a super high-pressure gas tank, and the one in the south on the other side was a vacuum tank. At the same time, the wind tunnel channel had two temperatures, heating and cooling. As long as the valve was opened, a huge pressure difference would be generated between the two gas tanks in an instant, and the high-pressure gas would instantly gush to the vacuum end. Under the action of this gas movement, the speed of the airflow would increase by 5 times, reaching the hypersonic standard.

And the plane on the wind tunnel platform had already spread its wings and flew high.

Under the impact of the huge airflow, the fighter was like a petrel fighting the waves, with a proud and tough posture, agile and stable.

As time passed slowly, the airflow in the wind tunnel gradually slowed down, and then the fighter slowly landed.

[Phase 2, the system ran successfully. ]

[Phase 3, preparation]

The hypersonic standard is just an appetizer, and the real hard bones are just beginning.

At this time, the little joy of the two successes just now was suppressed by everyone.

After hypersonic speed, it is hypersonic speed.

Under normal circumstances, 1 Mach is equal to 1 times the speed of sound, which is also equal to 340 meters per second.

If the wind tunnel flow rate is converted into Mach number, then 3-10 kilometers per second is equivalent to 30 times the speed of sound or 30 Mach.

The most basic data standard for hypersonic weapons is a speed exceeding Mach 5, so the research and development of hypersonic aircraft requires the support of hypersonic wind tunnels.

According to classification, aerospace planes can be divided into level one and level two. The first-stage space plane can be derived into aircraft such as hypersonic reconnaissance aircraft, suborbital bombers, and hypersonic passenger aircraft; while the second-stage can be derived into 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 force, and when both the pressure difference and the temperature difference are used, the engineers of Jiuzhou Technology also designed the impact stage unit produced by the explosion.

The energy of the explosion is used in the wind tunnel, and the strong pressure, temperature difference, and pressure difference can instantly generate hypersonic airflow.

Originally, Gu Qing wanted to add an arc accelerator, but the design team of the wind tunnel told Boss Gu a very regrettable message.

If the arc accelerator is to be added, the completion time of the wind tunnel project will be postponed for about one year. If the two systems are not compatible, the time will be extended.

Scientific experiments are not about piling up blocks, materials and technology can be piled on the project.

Experimental buildings such as large wind tunnels require not only materials and technology, but also the unification of equipment and technology. If the technology of other systems is added randomly, more design resources, energy resources, and material resources need to be reserved.

After countless troubles, there are still problems of maintenance and upkeep.

So at present, the first super-large wind tunnel of Jiuzhou Technology 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 containers made of special materials, and the vacuum tanks and pressure tanks that had worked once before also began to work for the second time.

As time passed, the air in the wind tunnel began to flow slowly.

The nameless fighter plane, at this time, gradually had red lines of flames on its wings.

The missile fixing devices under the cabin and wings also began to conduct emergency self-inspection and strengthening, and some unstable devices on the external branches were also retracted into the cabin.

[The third stage is ready, start]

Three

Two

One!

There was no sound, but everyone felt a kind of vibration that shook their hearts and minds, and even some trees on the mountains began to shake the tender new branches that grew this spring and summer.

And Gu Qing and others saw the air flow surging like a mushroom explosion through the pictures taken by the fixed camera.

Even the most arrogant people would not dare to enter this huge and rapid airflow, because the pressure difference and the explosion shock wave would instantly break through the fragile human body and tear it into real fragments.

Through combustion, the explosion finally occurred. The powerful airflow, under the effect of temperature difference and pressure difference, was countless times more powerful than the plus air cannon of the blue fat cat.

And the fighter plane, under the bombardment of the hypersonic wind, not only did not disintegrate, but also did not change its posture suddenly and was forced to crash.

It was like a mythical bird, still so brave, even like facing a hurricane, singing generously!

And while this fighter plane maintained its posture——

"2 Mach, 3 Mach, 4 Mach? ! ! 5 Mach? !!"

"Fuck? ! ! "

A young wind tunnel worker suddenly made a sound.

If it was during normal work, his frivolous and rude behavior would be quickly stopped by someone's eyes.

But today, even the engineers who were usually mature and steady were already frightened and could not express their excitement in words.

Even Gu Qing was slightly absent-minded when he saw this scene.

What is the concept of Mach 5?

The MiG-25, once the Red Scythe, once demonstrated a terrifying speed of Mach 3.2, which means that this fighter can easily avoid the Sidewinder missile with a speed of up to Mach 2.7.

However, the current fourth-generation 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 fighters.

The most popular J20 in Daxia currently has an official maximum flight speed of Mach 2.5, which is 2.5 times the speed of sound.

According to Daxia's long-term "false label" strategy, the maximum flight speed of the J20 may reach Mach 2.8, but it will never exceed Mach 3.

And this fighter, which can obviously carry people, can reach a maximum flight speed of Mach 5.

What does this mean?

Many staff members were shocked and even felt terrified.

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, was also checking 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 interfering.

When half an hour passed, the intelligent AI program Tiangongdu had given feedback data from 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 calmed down, Gu Qing smiled and suddenly said: "Congratulations everyone, we have finally taken the first step in 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 the code name within the project, which may be numbers, letters, or even some inexplicable symbols.

But if the experiment is successful, this fighter plane will have a name unique to it.
