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

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

Because it is the latest demonstration aircraft, for the safety of fighters and the lives of test pilots, parachutes are used to assist in landing.

Test pilot Ray just climbed down from the cabin, and instead of relying on the folding ladder, he jumped off on his own.

Obviously, Lei Gang felt good about this test flight, otherwise he would not have taken such a way to come down.

"How does supersonic cruising feel?"

Zhang Xingyang asked as he handed over a bottle of mineral water on the side.

"I feel better now, the first time I overcruised, I felt like my heart was going to jump out!"

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

"Professor Zhang, our anti-load clothing can actually be improved."

"The latest modification of the J-10 now, when maneuvering in supersonic conditions, the overload is really too big!"

Lei Gang's statement is not unreasonable, modern supersonic fighters are prone to overload of several G's when maneuvering.

This situation is especially noticeable above the J-10 fighter, and even because of the ability to cruise at supersonic speeds.

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

The acceleration of the J-10 is very fast, and even more so at the moment of entering supersonic speed, at this time the blood will surge upward, impacting the brain and causing a trance.

This is especially true when doing an up-and-down roll.

There will be black vision and red vision.

In the air, when the plane accelerates upwards to climb, the pilot's body also moves upwards.

Due to the accelerated increase in the speed of the aircraft, the blood flow in the blood vessels lags significantly, which can lead to a temporary lack of blood supply to the pilot's brain and black vision.

On the contrary, when the plane dives down, the pilot's blood accumulates too much in the head and causes excessive cerebral congestion, resulting in red vision in the fundus of the eyes.

At this time, anti-load clothing is needed to provide a more suitable pressure for the pilot to maintain the normal blood in the body.

In fact, the anti-load suit and the spacesuit developed by Zhang Xingyang before have similar functions.

It's just that the function of the spacesuit is slightly more complicated, after all, the situation faced is more extreme and harsh.

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

Zhang Xingyang looked at the ground crew who was doing various inspections for the fighter not far away and said:

"Didn't you come to measure you the other day?"

"That's preparing for the manufacture of anti-load clothing."

Because the pilot's personal height, arm length and leg length and other data are quite different, so the anti-load suit is actually specially customized for the individual.

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

Lei Gang took a sip of the mineral water in his hand, replenished his own water and asked.

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

The anti-load clothing they use now is still a relatively backward inflatable anti-load clothing.

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

Although this anti-load 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 reaction time of the inflatable anti-load suit is relatively long.

Not being able to complete the work of anti-overload in the first place is not good for the health of the pilot.

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

"The reaction speed is fast, but it's a lot heavier than your current anti-load suit."

Speaking of this, Zhang Xingyang looked Lei Gang up and down, smiled and said:

"You might feel like you're flying an airplane with a suit of armor in the future!"

"Huh?"

Lei Gang was a little confused:

"Is it that heavy?"

Here is actually Zhang Xingyang's exaggeration.

The pilot's operational flexibility was very important, and the control technology at this time had not yet evolved to the extent of brain insertion.

A pilot's hands are still precious.

Although the liquid-filled anti-load suit is a bit heavier than their previous anti-load suit, it weighs only one or two kilograms at most.

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

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

"Just kidding."

"In addition to the large overload, do you think there is anything wrong with it?"

Zhang Xingyang asked as he looked at the fighter jet who was being dragged back to the hangar by the ground truck in the distance.

"There's nothing big about it."

Lei Gang gave a high evaluation:

"Of all the planes I have flown there is no better fighter than him!"

As a professional test pilot, Lei Gang has flown almost 100 planes over the years, and no aircraft has ever received such an evaluation from him.

"It's just the weapon system, if only it could be better."

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

Zhang Xingyang said with some surprise.

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

It can be said that against the third-generation aircraft of various countries, the J-10 equipped with the Thunderbolt-9 air-to-air missile is almost the same as crushing!

This is also the reason why Zhang Xingyang did not put too much effort into this.

After all, in terms of the current strength of weapons, it is enough.

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

"Now everyone is pursuing over-the-horizon operations, and we are still using short-range air-to-air missiles."

Lei Gang frowned and said:

"Isn't it too far behind?"

As the first test pilot in China to contact the J-10, Lei Gang knows very well that today's Thunderbolt 9 is actually not at the same latitude as the AIM120 of Eagle Sauce.

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

It is also to let the military personnel of various countries see the development direction of future air warfare.

In future wars, the combat distances of manned fighters will certainly become farther and farther away.

"Our over-the-horizon air-to-air missiles, it will take a little bit of time."

Zhang Xingyang's eyes narrowed slightly, as if he had thought of something.

"However, even if an over-the-horizon air-to-air missile is developed, the possibility of equipping the J-10 first is not very great!"

"Why?" Lei Gang asked with some confusion.

However, he quickly reacted:

"You're saying that our next-generation fighter is on the verge of landing?"

Zhang Xingyang didn't say anything, but looked at the sunset that was gradually setting 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 fighters does not start anything, Zhang Xingyang is actually not necessary to say nothing like this.

Only if it is possible that the actual development of the new generation of fighters has already begun, the other side will not say anything due to the requirements of secrecy.

However, Zhang Xingyang didn't speak, purely because he thought the sunset was very beautiful and wanted to take a closer look.

"In addition to the weapon system, what are the problems with the J-10, you continue."

After coming back to his senses, Zhang Xingyang continued to chat with Lei Gang.

"No problem."

Lei Gang thought carefully for a while and then said:

"If I have to say, there are a bit fewer weapon hardpoints."

Because the J-10 is a single-engine medium fighter, it needs to carry a drop fuel tank for flight when carrying out combat missions.

This occupies the mounting position in the belly, wing roots, etc.

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

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

In terms of firepower endurance, there is a certain weakness.

"This problem should be relatively easy to solve."

Zhang Xingyang thought about it for a while, and there were several different solutions.

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

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

"You've worked hard this time."

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

"Let's get some rest!"

——

"No, Boss!"

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

"If this thing is put in here, something will go wrong!"

Zhang Xingyang didn't react, still looking at the solid rocket engine in front of him without refueling with an expressionless face.

This is actually a Thunderbolt 9 engine after it has been disassembled.

The reason why Geng Bo has such a big reaction is because Zhang Xingyang is ready to use the all-nitrogen anionic salt as a propellant as its fuel under the condition of weakening the passivator!

You know, with the reduction of the passivator, the performance will be improved, but the sensitivity will be very, very high.

The slightest bit of improper transportation and storage will explode!

"Don't worry, I've already done an experimental test."

Zhang Xingyang was silent for a while and then spoke:

"With a 12% reduction in passivator, there is no significant increase in sensitivity."

"And the performance of the propellant is 20 percent better!"

"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.

For such a risk, it is still not very acceptable.

"Even if you can convince me, it's hard to convince the military to use such a high-risk weapon." Geng Bo said with a frown.

"They would have agreed, if they knew that after changing the propellant, the speed and range of the missile would be able to reach a level beyond that of the AIM120."

"Even if they know the possible risks here, they must not hesitate!"

Zhang Xingyang said categorically.

Over-the-horizon combat is the norm in future air warfare in the atmosphere, and missiles as weapons are the most important thing here.

"Chief Master Song, what do you think?"

Geng Bo saw that he couldn't say anything about Zhang Xingyang, so he had to ask for help from Song Tianxing beside him.

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

"How did you do that?"

"Such an unnatural propellant?"

"Are you really human?"

Chief Master Song's soul three questions, even Zhang Xingyang, who was originally very calm, was a little nervous.

"Of course I'm human."

Zhang Xingyang defended his race.

"Now, the weapons of the new generation of fighters are also available."

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

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

"I'm sorry, I said the wrong thing."

"There are still a lot of problems with the next generation of fighters, and the structural design drawings you gave us have given us a lot of inspiration."

"However, there are still a lot of problems in avionics and radar."

"It is expected that it will take another two or three years for the prototype to come out."

Zhang Xingyang was a little disappointed, according to his previous estimates, under the condition that he gave most of the design drawings, he would be able to get a prototype within at least a year.

"Stealth paint, we're almost ready to complete it."

"Mr. Song, you still have to pay attention to it, at least make the appearance verification machine first, right?"

"This has been almost done, and it will be completed in a month at most."

Song Tianxing's team has not done nothing, and has already done a lot of work:

"It is expected that next month, we will be able to carry out aerodynamic verification in the wind tunnel."

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

"Then our latest improved Thunderbolt-9D seems to be able to only be verified on the J-10 S."

Zhang Xingyang said with a frown.

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

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

makes Zhang Xingyang always have a weird feeling.

"Is the stealth paint also going to be tried on the J-10?"

Geng Bo asked weakly on 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 able to get on the fourth-generation aircraft.

So during this period of time, the actual performance test platform of stealth coating does not know how to solve it.

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

Zhang Xingyang does not particularly agree with this.

At the beginning of the design, the J-10 did not consider the problem of stealth, and there was no point in blindly pursuing stealth.

"Mr. Song, do you think it's feasible?"

The chief engineer of Jianshi was at 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: "It's okay to give it a try!" ”

Hearing that the chief engineer of Jianshi agreed with his own point of view, Geng Bo patted Zhang Xingyang on the shoulder defiantly:

"I'm not bad, right?"

Zhang Xingyang felt a little unable to complain.

"Over-the-horizon, stealth design, supersonic cruise, super-maneuverable."

"Mr. Song, are we still a third-generation aircraft?!"
