A big country of aerospace with black technology

A war eagle painted in gray dances above the blue sky.

After completing a series of complex performance tests, the fighter jet slowly landed on the runway.

Because it is the latest verification aircraft, for the safety of the fighter and the lives of the test pilots, a drogue parachute is still used for assisted landing.

Test pilot Lei Gang climbed down from the cabin, instead of relying on the folding ladder, he jumped down by himself.

Obviously, Lei Gang felt pretty good during this test flight, otherwise he wouldn't have come down in this way.

"How does it feel to supercruise?"

Zhang Xingyang handed over a bottle of mineral water and asked.

"I feel better now. When I was in Super Tour for the first time, I felt like my heart was about to jump out!"

Lei Gang took the mineral water, did not drink it, and replied:

"Professor Zhang, our anti-G suit can actually be improved."

"The latest improved version of the J-10, when maneuvering at supersonic speed, the overload is too great!"

Lei Gang's statement is not unreasonable. Modern supersonic fighters are prone to overload of several Gs when maneuvering.

This situation is especially obvious on the J-10 fighter jets, even because of the ability to perform supersonic cruise.

"When entering the supersonic state, the whole person will still be in a trance for a while."

The acceleration of the J-10 is very fast, especially at the moment of entering supersonic speed. At this time, the blood will surge up, impact the brain, and cause a trance.

This is especially true when rolling up and down.

There will be black and red vision phenomenon.

Flying in the air, when the aircraft accelerates upwards and climbs, the pilot's body also moves upwards.

As the speed of the aircraft accelerates, the blood flow in the blood vessels is obviously lagging behind, which will cause the pilot's short-term brain blood supply to be insufficient and blacksight will appear.

On the contrary, when the plane dives and descends, the pilot's blood accumulates too much in the head and causes excessive cerebral congestion, which causes the fundus to congest and appear red vision.

At this time, an anti-G suit is needed to provide a more suitable pressure for the pilot and maintain normal blood in the body.

In fact, the anti-G suit has similar functions to the spacesuit developed by Zhang Xingyang and the others.

It's just that the functions of the space suit are slightly more complicated, after all, the situation faced is more extreme and harsh.

"The latest matching anti-G suit is already in the process of development."

Zhang Xingyang looked at the ground crew not far away who were doing various inspections on the fighter jets and said:

"Didn't you come here to measure your size a few days ago?"

"That's preparing for the manufacture of anti-G suits."

Because the personal height, arm length and leg length of the pilots are quite different, the anti-G suit is actually customized for the individual.

"It is said that the current anti-G suit has improved a lot of functions, right?"

Lei Gang took a sip of the mineral water in his hand to replenish his own moisture and asked.

He only found out about this news when he was measuring his body data a few days ago.

The anti-G suits they use now are relatively outdated inflatable anti-G suits.

When the overload is large, the anti-G suit starts to inflate automatically to resist the pressure.

Although this anti-G suit is relatively simple from a technical point of view, its performance is not very good.

Because it takes a certain amount of time to inflate, the response time of the inflatable anti-G suit is relatively long.

Failure to complete the anti-overload work in the first place will be detrimental to the pilot's health.

"Yes, the latest model of anti-G suit is liquid-filled." Zhang Xingyang said.

"The reaction speed is very fast, but it is much heavier than your current anti-G suit."

Having said that, Zhang Xingyang looked Lei Gang up and down, smiled and said:

"You may later feel like you're wearing a suit of armor and flying a plane!"

"Um?"

Lei Gang was a little confused:

"Is it that heavy?"

This is actually Zhang Xingyang's exaggeration.

The operational flexibility of the pilot is very important, and the control technology at this time has not yet evolved to the level of brain insertion.

The pilot's hands are still very precious.

Although the liquid-filled anti-G suits were heavier than their previous anti-G suits, they only weighed one or two kilograms at most.

It's not like the spacesuit developed by Zhang Xingyang and the others, which weighs more than 100 kilograms!

Without turning on the power system, it is difficult for the astronauts to carry out activities by themselves.

"Kidding."

"Besides the relatively large overload, do you think there is any problem with it?"

Zhang Xingyang looked at the fighter jets in the distance that were being dragged back to the hangar by the ground vehicle and asked.

"No big problem."

Lei Gang gave a very high evaluation:

"Among the planes I've flown, there's never been a better fighter!"

As a professional test pilot, Lei Gang has driven almost hundreds of aircraft over the years, and he has never had an aircraft that has received such an evaluation from him.

"It's just a weapon system. It would be great if it could be better."

"Isn't the Thunderbolt 9 now equipped with good performance?"

Zhang Xingyang said with some surprise.

As the newly developed short-range air-to-air combat ammunition, Thunderbolt 9 is equipped with the super maneuverability of the latest improved J-10.

It can be said that against the current third-generation aircraft in various countries, the J-10 equipped with Thunderbolt 9 air-to-air missiles is almost a crushing existence!

This is also the reason why Zhang Xingyang didn't put too much effort into this aspect.

After all, from the current weapon strength, it is enough.

As for more advanced weapons, we need a more powerful platform, which is our own fourth-generation aircraft.

"Now everyone is pursuing beyond visual range operations, and we are still using short-range air-to-air missiles."

Lei Gang frowned and said:

"Is it too backward?"

As the first test pilot in China to get in touch with the J-10, Lei Gang is very clear that today's Thunderbolt 9 is actually not at the same latitude compared to Yingjiang's AIM120.

AIM120 air-to-air missiles, since Eagle Sauce was officially equipped eight years ago, have achieved a lot of results on this battlefield.

It also allows soldiers from various countries to see the development direction of future air combat.

In future wars, the engagement distance of manned fighter jets will definitely be farther and farther.

"Our beyond-visual-range air-to-air missiles still need a little time."

Zhang Xingyang narrowed his eyes slightly, as if thinking of something.

"However, even if the beyond-visual-range air-to-air missile is developed, the possibility of being equipped with the J-10 first is not very great!"

"Why?" Lei Gang asked with some doubts.

However, he quickly reacted:

"You mean, our new generation of fighter jets is almost ready?"

Zhang Xingyang didn't say anything, but was fascinated by the gradually setting sun in the distance.

Although he didn't get the answer he wanted, Lei Gang was still very happy.

Because he understands that if the new generation of fighter jets has not started, there is actually no need for Zhang Xingyang to say nothing.

Only when it is possible that the actual research and development of a new generation of fighter jets has already started, the other party will not say anything out of confidentiality requirements.

But Zhang Xingyang didn't speak, he just thought the sunset was beautiful and wanted to take a closer look.

"Besides the weapon system, what else is wrong with the J-10, you continue to talk."

After recovering, Zhang Xingyang continued to chat with Lei Gang.

"No problem."

After thinking carefully for a while, Lei Gang said:

"If you have to say it, there are a little less weapon mount points."

Because the J-10 is a single-engine medium-sized fighter, it needs to mount auxiliary fuel tanks for flight when performing combat missions.

This occupies the mount positions on the belly, wing roots, etc.

As a result, the missile mount points that the J-10 can actually use are only 2+2, a total of four points.

Compared with the F-16 fighter 4+2 of the same level, there is a certain gap.

In terms of firepower and battery life, there are certain weaknesses.

"This problem should be considered relatively easy to solve."

Zhang Xingyang thought for a while and came up with several different solutions.

For example, missile pylons are added to the wingtips, and the front and rear herringbone beams are used to connect the missile launch slide rails.

All of them can increase the missile loading capacity of the J-10 fighter jets to a certain extent.

"You worked hard this time."

Patting Lei Gang's thick shoulder, Zhang Xingyang said.

"Go and rest!"

——

"No, boss!"

Geng Bo looked at Zhang Xingyang who was staring at a solid rocket motor in front of him and shouted:

"If you put this thing in here, there will be problems!"

Zhang Xingyang didn't respond at all, and still stared blankly at the unfueled solid rocket motor in front of him.

This is actually the engine part of a Thunderbolt 9 disassembled.

The reason why Geng Bo had such a big reaction was because Zhang Xingyang was going to use the all-nitrogen anion salt as the propellant, under the condition of weakening the passivator, as its fuel!

You should know this thing. In the case of reduced passivation agent, although the performance will be improved, the sensitivity will become very, very high.

A little bit of improper transportation and storage can cause an explosion!

"Don't worry, I've done experimental tests."

After being silent for a while, Zhang Xingyang said:

"In the case of a 12% reduction in passivation agent, there will be no significant increase in sensitivity."

"And the performance of the propellant has increased by 20%!"

"It's worth the risk!"

Even Geng Bo, who can be regarded as radical in this era, can only be regarded as conservative compared to Zhang Xingyang.

Such a risk is still not acceptable.

"Even if you can convince me, it will be difficult for you to convince the military to use such high-risk weapons." Geng Bo said with a frown.

"They will agree if they know that after changing the propellant, the speed and range of the missile can reach a level beyond that of AIM120."

"Even if they know the possible risks here, they must have no hesitation!"

Zhang Xingyang said firmly.

Combat beyond visual range is the normal state of air combat in the atmosphere in the future, and missiles as weapons are the top priority here.

"Master Song, what do you think?"

Seeing that he couldn't speak against Zhang Xingyang, Geng Bo had no choice but to ask Song Tianxing beside him for help.

Song Tianxing was originally frowning, looking at the rocket engine in front of him that was not loaded with solid fuel.

When Geng Bo asked his opinion, he raised his head, first glanced at Geng Bo, and then stared at Zhang Xingyang:

"how did you do it?"

"Such a propellant against the sky?"

"Are you really human?"

Master Song's soul asked three times, even Zhang Xingyang, who was originally very calm, couldn't hold back.

"Of course I'm human."

Zhang Xingyang justified his racial issue.

"Now, the weapons for the new generation of fighter jets are also available."

"Mr. Song, when will you be able to make the next generation of fighter jets?"

Song Tianxing also came back to his senses at this time, and realized that he had just said something wrong:

"Sorry, I said the wrong thing."

"There are still many problems with the next generation of fighter jets. The design drawings you gave us have given us a lot of inspiration."

"However, there are still many problems in avionics and radar."

"It is expected that the prototype will take two or three years before it can come out."

Zhang Xingyang was a little disappointed. According to his previous estimation, with most of the design drawings given by him, the prototype could be produced within at least a year.

"Stealth paint, we are about to complete the development."

"Mr. Song, you should hurry up, at least make the appearance verification machine first?"

"This has been almost done, and there is still a month at most before it can be completed."

Song Tianxing and his team did not do nothing, they have done a lot of work:

"It is expected that next month, it will be able to enter the wind tunnel for aerodynamic verification."

Even if the structure given by Zhang Xingyang is a design that has experienced many tests in later generations, it still needs verification work before it can truly be recognized by everyone.

"Then our newly improved Pili-9D, it seems that it can only be verified on the J-10S."

Zhang Xingyang frowned and said.

J-10 finally completed the improved model, which is called J-10S.

The Thunderbolt missile, which was originally designed and improved for the fourth-generation aircraft, was finally given to the J-10 after the magic modification.

Zhang Xingyang always had a weird feeling.

"Do you want to try the stealth paint on the J-10 as well?"

Geng Bo asked weakly from the side.

He doesn't know much about fighter jets, but judging from the situation just now, it will take a long time for the stealth paint to be used on fourth-generation aircraft.

So during this period of time, the actual performance test platform for stealth coatings still doesn't know how to solve it.

"J-10 pursues stealth performance, so the structure of the fuselage needs to be greatly changed."

Zhang Xingyang did not particularly agree with this.

At the beginning of the design of the J-10, the issue of stealth was not considered. There is no point in blindly pursuing stealth.

"President Song, do you think it's feasible?"

The head teacher of J-10 was on the scene, and Zhang Xingyang didn't want to say too much, but asked Song Tianxing to explain.

Who would have thought, after a little thought.

Song Tianxing said: "You can try it!"

Hearing that the chief teachers of J-10 agreed with his point of view, Geng Bo patted Zhang Xingyang on the shoulder provocatively:

"My idea is not bad!"

Zhang Xingyang felt a little unable to complain.

"Beyond visual range, stealth design, supersonic cruise, super maneuverable."

"President Song, is this still a third-generation machine?!"
