s: The second update will be sent s: Tian Cheng, the former journalist who mined uranium in the previous chapter, was played by a classmate of "Wu Shan Xia Ke" who is an enthusiastic reader.
He must insist on playing a heinous person.
Of course, he cannot refuse such a tricky request, so he got his wish oohaha "Wahahahaha, it's so enjoyable, it's so enjoyable, this is the plane that men fly, wowhahaha" Wei Dabao laughed wildly, the expression on his face was distorted with excitement.
At this time, he must not even recognize his mother. .
High-quality aviation kerosene is continuously fed into the afterburner by an electric pump, and then burned violently in high-pressure air, transforming it into surging power.
High-temperature gas of thousands of degrees Celsius was ejected from the tail nozzle at an unimaginable speed.
The resulting powerful thrust accelerated the Chengdu Aircraft prototype to 2.7 times the speed of sound.
Even wearing a hydraulic compensation suit cannot completely offset the pressure caused by strong overload.
Wei Dabao was firmly pressed on the seat by the powerful reaction force.
The powerful stimulation brought by exceeding the speed of sound caused his adrenaline hormones to be secreted rapidly, making his mood extremely high.
"Wow, wow, wow, this is the fastest manned aircraft in the world.
This is the one that men fly."
Wei Dabao's ecstatic voice echoed on the radio.
On the control tower of Flight Test Site No. 88, a group of people looked at each other.
There are many stars in this group of people, including many senior officers from the Air Force, Hainan Airlines and Army Aviation.
There are also the heads of the three aircraft factories of Chengdu Aircraft, E-Aircraft and Guangzhou Aircraft.
Yes, they moved the supersonic flight test venue here.
Last month, they conducted a test flight in the mainland, which made the neighbors uneasy, and then they were brought to Wen Desi.
So he was driven to Flight Test Site No. 88.
This flying field is located on the east coast of the Aral Sea near the red sand desert.
After taking off, we flew into the desert.
There were not many people there and it was very desolate.
They could do whatever they wanted.
Of course, there are also more remote places in the country, but the basic conditions in those places are not good.
First of all, the airport facilities do not meet the conditions.
The staff looked at the map for several days and compared various parameters before selecting Airport No. 88.
Air Force Deputy Commander-in-Chief General Lin Shenhe coughed a few times and said: "These guys are playing too crazy.
I'd better remind them not to get into trouble."
"I'm not worried about them.
They are all veterans with more than 5,000 hours of service.
There is nothing to worry about.
I am worried that they will damage the plane for me," Air Force Commander-in-Chief General Meng Shu said angrily.
"It's outrageous that someone who is already dozens of years old is still so crazy.
Mr.
Meng, when they come down, they must be locked up in a dark room for a few days," Jin Hai encouraged from the side.
Meng Shu rolled his eyes at him and scolded him with a smile: "You are worried that the world will not be in chaos because they have taken the lead, and you feel unhappy, right?"
"Hahaha" everyone roared with laughter.
At this time, a HNA general who was staring at the radar screen suddenly said: "Well, they have slowed down."
A staff officer said: "Commanders, all three test aircraft have turned off their afterburning engines in accordance with the test requirements."
"How many minutes has it been?"
a general asked with some dissatisfaction.
Several generals also found it unsatisfactory.
This supersonic speed was really powerful, but the time was too short.
Chengdu Aircraft's chief engineer stood up and explained: "Flying at supersonic speeds consumes a lot of fuel.
At cruising speed, the fuel is enough for more than three hours.

If the afterburner is turned on, it will be gone in twenty minutes, and it will also intensify."
The engine wear and tear, so we recommend not to fly with afterburner for more than 8 minutes continuously."
"What can you do in eight minutes?"
an Army Aviation officer muttered.
"Enough to knock you down eight times," an air force man next to him said back to him.
"When will you have this ability?
Why don't you go up and practice and see who can knock whom down?"
"I'm still afraid that I haven't played against each other for several years, and I don't know how far your level has dropped."
"Bah, let me lower my level and see if you can still fit on the plane."
Meng Shu ignored the quarrels of the group and said calmly: "It seems that this turbojet engine still consumes too much fuel."
"Yes, Mr.
Meng, even the latest turbojet type 5 and axial flow turbojet engine we are using now has less than ideal fuel consumption.
Before the turbofan engine is practical, it can only reach supersonic speed.
Use this."
Chengfei's chief engineer said helplessly.
At this time, Jin Hai said: "Mr.
Meng, these aircraft are already very mature, when will they be equipped with the troops?"
His words spoke to the minds of most people, and everyone was waiting for the answer from the Air Force boss.
This question.
It has been almost ten years since the first jet test aircraft made its first flight on January 11, 1924.
There have been several changes from jet to aircraft model.
In 1926, Chengdu Aircraft's Type 1024 test aircraft broke the sound barrier for the first time and achieved the first supersonic flight in this plane.
And this time it was an experiment that exceeded twice the speed of sound.
Wen Desi is a person who likes mature products, so he doesn't like all the previous models.
Even if his subordinates are scratching their heads in anxiety, he is not anxious at all.
They just instruct various design institutes and aircraft factories to use these things as technical reserves and continue to develop better products.
Anyway, it is not a time of war, and the armaments are sufficient.
China has enough time to perfect its weapons.
At this time, the three test aircraft in the sky have dropped below the speed of sound, but their speed at this moment is still around 800 kilometers, which is a speed that traditional piston propeller aircraft cannot reach.
The shapes of these three aircraft are all different.
The fastest flying test aircraft No. 6605, reaching Mach 2.7, is a product of Chengdu Aircraft Corporation of China.
It has a double vertical tail and a single-wing configuration.
It looks a bit like the Soviet Union's MiG-25 in the original time and space.
"Foxbat".
Yes, it is the famous flying stainless steel.
The second fastest is Guangzhou Aircraft's No. 6805 test aircraft, which looks a bit like an enlarged "Aerial Cai Xing" and flies to Mach 2.5. .
Finally, there is the No. 6705 test machine produced by E-fly.
It looks like the F4 "Ghost" of the original time and space, and it flew to Mach 2.4.
Well, their dimensions, empty weight and other data are not much different, and they use the same engine.
They are both twin-engine heavy-duty fighters, which can be regarded as fighters of the same level.
Of course, none of them are equipped with weapons yet.
"I said Dabao, this thing is not suitable for your Army Air Force.
You just have to play with it.
Don't get too obsessed."
A sour voice came from Wei Dabao's earphones.

This guy is Brigadier General Hua Gaimu of the Air Force.
He was a step too late just now and failed to grab the fastest test aircraft No. 6605.
In the end, he could only choose the slowest test machine No. 6705.
Wei Dabao, who got the "magic machine" first, didn't care about this little jealousy at all, and said casually: "What's wrong with it?
I think it's very suitable for our Army Airlines.
Look at the sonic boom just now, how...
Awesome.
If you fly around the enemy group at low altitude, it will be more effective than bombs."
"Bah, Dabao, you are so whimsical.
Even if you have the ability to fly at supersonic speeds at low altitude, your superiors won't be able to spare you."
Chu Wangyuan, the test pilot of the No. 6805 test machine, was heard on the channel again.
The voice of the major general.
The three test pilots are all generals, one major general and two brigadiers.
And now there are a bunch of generals in the control tower preparing to be test pilots.
Each aircraft can have a dozen prepared test pilots, with the lowest being brigadiers.
This is probably the highest-ranking test flight team in history.
Of course, they are only part-time.
"This aircraft is good.
I will suggest it when I get back that it must be equipped with Army Airlines first," Wei Dabao said.
Hua Gaimu said disapprovingly: "I said, your Army Air Force needs a rough fighter.
It would be nice to have attack aircraft.
Even if the fighter jets provide support, just call our air force."
"Tch, wait until your Air Force plane arrives and the day lilies are cold, okay?
It's not like there's no precedent," Wei Dabao retorted unceremoniously.
Cooperation between the military services has always been a problem, no matter what time it is.
The strange relationship between the army and navy of old Japan is a special case, so I won’t go into it.
No matter how good the relationship between the services is and how good the communication conditions are, problems will still arise.
For example, in the US military in the original time and space, third-class people were often accidentally bombed by first- and second-class people.
In many operations, more third-class people were killed by first- and second-class people than by the enemy. many.
Wen Desi from later generations knew this shortcoming all too well, so the Chinese Army in this plane has its own aviation force, not just helicopters, but also fighter jets, attack aircraft, and light bombers, but it is not equipped with large and medium-sized bombers and strategic bombers.
Transport aircraft.
The three test aircraft quickly returned to the airport.
These two are the elite among the Chinese pilot elites, and are among the top ten aces in the world.
This kind of test flight is not difficult for them at all.
As soon as they got off the plane, a large group of ground staff rushed over and dragged the plane into the hangar for inspection.
At the same time, a large number of manufacturer technicians also came together to extract various data.
"Why aren't we equipped this time?"
The three general test pilots excitedly entered the control tower, but were given a bucket of cold water in the face.
They all felt that they could not understand why such a good thing was not used.
"Why do you think this kind of thing is good?"
Meng Shu said disdainfully: "You guys, these things are nothing at all."
Seeing that these guys were still unconvinced, Meng Shu had no choice but to explain: "If this was a war era, we would definitely be equipped like this.
But now is a peaceful era, and there is no sign of a war breaking out within the next few years. .
In the case of small-scale conflicts, our current turboprop fighter jets can already handle it, so why waste resources on installing something that will become obsolete in a few years?"
"So, when will the next generation of fighter jets be put into service?"

someone asked.
"This central government has taken all things into consideration.
Please be patient.
I can guarantee that you will not be kept waiting for too long."
Hangar.
There was a crowd of people gathered in front of Chengdu's No. 6605 test machine.
Several engineers were checking back and forth with test instruments, reporting data from time to time, which would arouse applause from the whole room.
This group of people were all technicians from three manufacturers, and they were all having a heated discussion.
"This new type of material is really good and can withstand high temperatures above 400 degrees Celsius for a long time without losing too much strength."
"The most important thing is that it is very light, lighter than aluminum alloy.
It has the strength and high-temperature strength close to titanium alloy, but is lighter than aluminum alloy.
This is simply the most ideal material for the aviation industry."
"Hey, it's a pity that it's a bit expensive.
Although it's cheaper than titanium alloy, it's still more than twice as expensive as aluminum alloy."
"Actually, B-type porcelain steel is quite suitable as an aviation material.
If we didn't have this mithril, we could also choose B-type porcelain steel.
It's a bit heavier, but it's cheaper."
The type B porcelain steel they are talking about is also the type B iron-aluminum alloy.
Now, in order to confuse the outside world, various new alloys introduced during this period have been given very funny nicknames.
The two iron-aluminum alloys are called Type A and Type B porcelain steel, and Mithril is the body material on these three aircraft.
There is also a kind of fine gold, which is an armor material.
In the history of human aviation, when airplanes broke through the sound barrier and began to sprint toward Mach 2.5 or above, a brand new obstacle began to stand in front of mankind.
That is the "thermal barrier" caused by the high temperature generated by the rapid friction between the high-speed flying body and air molecules.
When the aircraft flies at a speed of Mach 2, its body surface temperature has reached 107 degrees Celsius.
When the aircraft continues to increase the throttle and sprints towards Mach 2.5, its body surface temperature will reach more than 200 degrees.
According to calculations, if the aircraft reaches Mach number 3, its body surface temperature will reach 300 degrees.
High temperature will bring a series of troubles.
Generally speaking, aircraft body materials are all aluminum alloys.
Even high-strength aluminum alloys have a melting point of only 400,500 degrees Celsius.
At a high temperature of 300 degrees, traditional aluminum alloy skin materials will become thicker than paper.
It must be fragile.
If coupled with the huge pressure brought by high speed, the body at this time will deform or even collapse.
Of course we all know how to solve this problem, using titanium alloy.
Yes, titanium alloy can indeed be used, but when the Soviets in the original space and time were manufacturing the MiG-25, their titanium alloy processing capabilities were very weak and they could not make a qualified airframe, so they got creative and started playing with stainless steel aircraft. .
This is also the origin of the nickname "Flying Stainless Steel".
However, China in this plane is not as embarrassed as those who use stainless steel to make aircraft.
Wen Desi has better materials in his hands, and there is more than one kind.
With the processing capabilities of China on this plane, it is certainly no problem to make a titanium alloy aircraft, but why not use it if there are better and cheaper materials?
Porcelain steel is actually prepared for warships, tanks, cannons, etc.
The main reason is that these weapons are used more.
Of course, Wen Desi would not forget the airplane.
What he prepared for the airplane was another new type of alloy, "magnesium-sodium alloy."
The performance of this thing that uses a legendary metal from mythology as its nickname is extremely unparalleled.
Its specific gravity is about half that of aluminum-magnesium alloy, only 1.
The strength of 38 is slightly lower than titanium alloy, higher than stainless steel, and the specific strength is much higher than porcelain steel; the high-temperature strength is slightly lower than titanium alloy, but it can fully withstand the impact of fighter jets at high altitudes.
