The gray-painted war eagle 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 verification aircraft, for the safety of the fighter and the life of the test pilot, a deceleration parachute is still used to assist the landing.
Test pilot Lei Gang climbed out of the cabin and jumped out by himself without relying on the folding ladder.
Obviously, Lei Gang felt pretty good during this test flight, otherwise he would not have come down in this way.
"How does it feel to cruise at supersonic speed?"
Zhang Xingyang asked as he handed over a bottle of mineral water.
"I feel a little better now. When I went on super patrol for the first time, I felt like my heart was going to jump out of my chest!"
Lei Gang took the mineral water without drinking it and replied:
"Professor Zhang, our anti-German suit can actually be improved."
"The latest improved version of the J-10 now has too much overload when maneuvering at supersonic speeds!"
Lei Gang's statement is not unreasonable. Modern supersonic fighter jets are prone to overloads of several G when maneuvering.
This situation is especially obvious on the J-10 fighter jet, even because it can cruise at supersonic speeds.
"When entering the supersonic state, the whole person will be in a trance for a while."
The J-10 accelerates very quickly, especially at the moment it enters supersonic speed. At this time, the blood will surge up, impacting the brain, and causing a trance.
This is especially true when rolling up and down.
Black vision and red vision will occur.
Flying in the air, when the aircraft accelerates upward and climbs, the pilot's body also moves upward.
As the speed of the aircraft accelerates, the blood flow in the blood vessels lags behind significantly, which will cause the pilot to temporarily lack blood supply to the brain and cause black vision.
On the contrary, when the aircraft dives and descends, too much blood accumulates in the pilot's head, causing excessive cerebral congestion, causing congestion in the eyes and red vision.
At this time, anti-gravity suits are needed to provide the pilot with a more appropriate pressure and maintain normal blood flow in the body.
In fact, the anti-Dutch suit and the space suit developed by Zhang Xingyang and others have similar functions.
It's just that the function of the space suit is a little more complicated, after all, the situations faced are more extreme and harsh.
"The latest supporting anti-German clothing 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 I come here just to measure you a few days ago?"
"That's preparing for the manufacture of anti-German suits."
Because the personal height, arm length, leg length and other data of pilots are quite different, the anti-gravity suit is actually specially customized for the individual.
"It is said that the current anti-German suit has a lot of improved functions, right?"
Lei Gang took a sip of the mineral water in his hand and replenished his own water.
He only found out about this news when he was measuring his body data a few days ago.
The anti-gravity suits they use now are still relatively backward inflatable anti-gravity suits.
When the overload is large, the anti-gravity suit begins to inflate automatically to resist the pressure.
Although this kind of anti-gravity 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 inflatable anti-gravity suits is relatively long.
Failure to complete the anti-overload work at the first opportunity is detrimental to the pilot's health.
"Yes, the latest model of anti-German suit uses a liquid-filled type." Zhang Xingyang said.
"The reaction speed is very fast, but it is much heavier than your current anti-gravity suit."
Having said this, Zhang Xingyang looked Lei Gang up and down, smiled and said:
"You might feel like you're wearing a suit of armor and flying a plane!"
"Um?"
Lei Gang was a little confused:
"Is it that heavy?"
Zhang Xingyang is actually exaggerating here.
The pilot's operational flexibility is very important. At this time, the control technology has not yet evolved to the level of brain insertion.
The hands of pilots are still very valuable.
Although the liquid-filled anti-gravity suit is heavier than their previous anti-gravity suit, it only weighs one or two kilograms at most.
It's not like the space suit developed by Zhang Xingyang and others, which weighs more than one hundred kilograms!
Without turning on the power system, it is difficult for the astronauts to carry out activities alone.
"Kidding."
"Besides the relatively large overload, do you think there are any other problems with it?"
Zhang Xingyang asked as he looked at the fighter jet in the distance that was being towed back to the hangar by a ground service vehicle.
"There's no big problem."
Lei Gang gave a very high evaluation:
"Among the aircraft I have flown, there is no better fighter than him!"
As a professional test pilot, Lei Gang has flown almost hundreds of aircraft over the years, and no aircraft has ever received such evaluation from him.
"It's just a weapon system. It would be nice if it could be better."
“Isn’t the performance of the Thunderbolt 9 equipped now very good?”
Zhang Xingyang said with some surprise.
As the latest developed close-range air-to-air combat bomb, the Pili 9 is equipped with the latest improved J-10's super maneuverability.
It can be said that compared with the current third-generation aircraft from various countries, the J-10 equipped with PL9 air-to-air missiles is almost a crushing presence!
This is also the reason why Zhang Xingyang did not put too much energy into this aspect.
After all, judging from the current strength of the weapon, it is enough.
As for more advanced weapons, they require more powerful platforms, which are our own fourth-generation aircraft.
"Now everyone is pursuing beyond-visual-range combat, and we are still using short-range air-to-air missiles."
Lei Gang frowned and said:
"Is it too backward?"
As the first domestic test pilot to come into contact with the J-10, Lei Gang knew very well that today's Thunderbolt 9 is actually not at the same latitude as the AIM120 of Yingjiang.
The AIM120 air-to-air missile has achieved many results on this battlefield since it was officially equipped by Yingjiang eight years ago.
It also allows military personnel from various countries to see the development direction of future air combat.
In future wars, the combat distance of manned fighter jets will definitely become farther and farther.
"Our beyond-visual-range air-to-air missiles still need a little time."
Zhang Xingyang's eyes narrowed slightly, as if he thought of something.
"But even if a beyond-visual-range air-to-air missile is developed, it is not very likely that it will be equipped with the J-10 first!"
"Why?" Lei Gang asked with some confusion.
However, he quickly reacted:
"You're saying that our new generation of fighter jets is almost ready?"
Zhang Xingyang didn't say anything, but looked at the setting sun in the distance in trance.
Although he didn't get the answer he wanted, Lei Gang still looked very happy.
Because he understood that if the new generation of fighter jets had not started, there was actually no need for Zhang Xingyang to say nothing.
It is only possible that the actual research and development work of the new generation fighter jets has begun, and the other party will say nothing out of confidentiality requirements.
However, Zhang Xingyang didn't say anything. He simply thought the sunset was beautiful and wanted to take a closer look.
"Besides the weapons system, what other problems does the J-10 have? Keep talking."
After coming back to his senses, Zhang Xingyang continued chatting with Lei Gang.
"It's no problem."
Lei Gang thought carefully for a while and then said:
"If I have to say it, there are a little few weapon mounting 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 mounting positions on the belly, wing roots, etc.
As a result, the J-10 can actually use only 2+2 missile mounting points, a total of four points.
Compared with the F-16 fighter jet 4+2 of the same level, there is a certain gap.
In terms of firepower and endurance, there are certain weaknesses.
"This problem should be relatively easy to solve."
Zhang Xingyang thought for a moment and came up with several different solutions.
For example, missile pylons are added to the wingtips, and front and rear herringbone beams are used to connect the missile launch rails.
All can increase the missile load capacity of the J-10 fighter to a certain extent.
"You worked hard this time."
Zhang Xingyang said after patting Lei Gang's thick shoulder.
"Go and have a good 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 react at all, still looking at the unfueled solid rocket motor in front of him with an expressionless face.
This is actually the disassembled engine part of a Thunderbolt 9.
The reason why Geng Bo had such a big reaction was because Zhang Xingyang planned to use the total nitrogen anion salt as propellant as its fuel while weakening the passivation agent!
You need to know that when the passivation agent is reduced, although the performance will be improved, the sensitivity will become very, very high.
An explosion can occur if the product is not transported or stored properly at all!
"Don't worry, I have already done experimental tests."
Zhang Xingyang said after being silent for a while:
"With a 12% reduction in passivation agent, there will be no significant increase in sensitivity."
"And the performance of the propellant has been improved by 20%!"
"The risk is worth it!"
Even Geng Bo, who can be considered a radical in this era, can only be considered conservative compared to Zhang Xingyang.
It is still not acceptable for such risks.
"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 would agree if they knew that after changing the propellant, the missile could reach speeds and ranges beyond those of the AIM120."
"Even if they knew about the possible risks here, they would definitely not look back!"
Zhang Xingyang said decisively.
Beyond visual range combat will be the norm in air combat within the atmosphere in the future, and missiles as weapons are the top priority here.
"Chief Master Song, what do you think?"
Geng Bo saw that he could not defeat Zhang Xingyang, so he had to ask for help from Song Tianxing beside him.
Song Tianxing originally frowned and looked at the rocket engine in front of him that was not yet 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 it?"
"Such a heaven-defying propellant?"
"Are you really human?"
General Master Song's three soul questions made even Zhang Xingyang, who was originally very calm, a little unable to hold his nerve.
"Of course I'm human."
Zhang Xingyang defended his racial issues.
"Now, the weapons of a new generation of fighter jets are available."
"President Song, when will you be able to produce the next generation fighter jet?"
Song Tianxing also came to his senses at this time and realized that he had just said the wrong thing:
"Sorry, I said the wrong thing."
"There are still many problems with the next generation fighter jets. The design drawings you gave us for structural design gave us a lot of inspiration."
"However, there are still many problems in avionics and radar."
"It is expected that it will take another two or three years for the prototype to be released."
Zhang Xingyang was a little disappointed. According to his previous estimates, with most of the design drawings given by him, the prototype could be produced within at least a year.
"We are almost finished developing the stealth paint."
"Mr. Song, you should hurry up and at least build the appearance verification machine first, right?"
"This is almost done. It will be completed in a month at most."
It’s not that Song Tianxing and his team have done nothing, they have already done a lot of work:
"It is expected that next month, we will be able to enter the wind tunnel for aerodynamic verification."
Even if the structure given by Zhang Xingyang is a design that has gone through many tests in later generations, it still needs verification work before it can truly be recognized by everyone.
"It seems that our latest improved PL-9D can only be verified on the J-10S."
Zhang Xingyang said with a frown.
The final improved model of the J-10 was called the J-10 S.
The improved Thunderbolt missile was originally designed for the fourth-generation aircraft, but was eventually given to the J-10 after the magic modification.
Zhang Xingyang always has a strange feeling.
"Then the stealth paint should also be tried on the J-10?"
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 stealth paint to be available on fourth-generation aircraft.
So during this period of time, we still don’t know how to solve the actual performance test platform of stealth coatings.
"The J-10's pursuit of stealth performance requires major changes to the structure of the fuselage."
Zhang Xingyang does not particularly agree with this.
At the beginning of the design of the J-10, stealth issues were not considered, and blind pursuit of stealth makes no sense.
"Mr. Song, do you think it's feasible?"
The chief commander of Jian Shi was at the scene. Zhang Xingyang didn't want to say too much, but let Song Tianxing explain.
Who would have thought, after thinking about it for a while.
Song Tianxing said: "You can give it a try!"
Hearing that the J-10 commander 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 maneuverability."
"Mr. Song, are we still a third-generation machine?!"
