PS: The second more will be sent......

PS: Tian Cheng, a former big reporter who dug uranium mines in the previous chapter, was played by the friendship of the enthusiastic reader "Wushan Knight", he must insist on playing a heinous criminal, such a tricky request, of course, he can't refuse, and he got his wish...... O(∩_∩)O haha~

..............................................................................

"Wow-haha-ha, it's enjoyable! It's enjoyable! It's so enjoyable! This is the plane that the master is flying, wahahaha......" Wei Dabao laughed wildly, the expression on his face was distorted with excitement, and he must not even recognize his mother at this time.

The high-quality aviation kerosene is continuously fed into the afterburner by an electric pump, and then burned violently in high-pressure air to transform it into surging power. Thousands of degrees Celsius of hot gas ejected from the tail vent at unimaginable speeds, and the resulting powerful thrust accelerated the prototype to 2. 7 times the speed of sound!

Even wearing a hydraulic compensatory suit cannot fully counteract the pressure caused by a strong overload. Wei Dabao was firmly pressed on the seat by the strong reaction force, and the powerful stimulation brought by the speed of sound made his adrenal hormones secrete rapidly, making his emotions high to the extreme.

"Wow Ka Ka Ka Ka, this is the fastest manned aircraft in the world at the moment! It's the guy who will drive this!" The voice of the little treasure dancing in ecstasy echoed on the radio......

On the conning tower of the No. 88 flight test site, a group of people looked at each other. There will be a star-studded crowd of these people, a large number of high-ranking officers of the Air Force, Navy and Army Aviation. There are also the heads and brains of the three aircraft factories of Chengfei, Efei and Guangfei.

That's right, they moved the site of supersonic flight tests here. Last month, they took a test flight in the mainland, which made their neighbors uneasy, and then they were stabbed to Wen Desi. So he was driven to the No. 88 flight test site.

This airfield is located on the eastern shore of the Aral Sea, close to the Red Sand Desert, and after taking off, they fly into the desert, and there are few people in that place, and it is very desolate, and they can toss it as much as they want. Of course, there are more remote places in China, but the basic conditions in those places are not good, and the airport facilities do not meet the conditions in the first place. The staff officers picked on the map for several days and compared various parameters before they selected the airfield No. 88.

General Lin Shenhe, deputy commander-in-chief of the Air Force, coughed dryly a few times and said: "These guys are playing too crazy, let's remind them, don't have an accident......

"I'm not worried about them, they're all old birds for more than 5,000 hours, so there's nothing to worry about. I'm worried that they will break the plane for me!" said General Meng Shu, commander-in-chief of the Air Force, angrily.

"It's dozens of years old, and it's so crazy, it's so unusual. Mr. Meng, when they come down, we must lock them up in a small black house for a few days......" Jin Hai encouraged beside him.

Meng Shu glanced at him, and scolded with a smile: "You kid is afraid that the world will not be chaotic, because they took the lead, and you are unhappy, right?"

"Hahaha......" The crowd burst into laughter.

At this time, a HNA general who was staring at the radar screen suddenly said: "Uh, they slowed down......"

A staff officer said: "Chiefs, the three test planes have now turned off the afterburner engines in accordance with the test requirements......

"It's only been a few minutes?" asked one of the generals, a little dissatisfied. Several generals also found it not very enjoyable, this supersonic speed is really powerful, but this time is too short.

Cheng Fei's chief engineer stood up and explained: "Supersonic flight consumes a lot of fuel, enough fuel for more than three hours at cruising speed, and if you turn on afterburner, it will be gone in more than 20 minutes, and it will also aggravate the wear and tear of the engine." Therefore, we recommend that you do not fly for more than 8 minutes in a row when you are flying with afterburner......"

"Eight minutes...... What can you do in eight minutes?" muttered an Army Aviation officer.

"That's enough to knock you down eight times...... "One of the Air Force members next to him replied.

"When did you kid have this ability? Do you want to go up and practice and see who knocks who down......

"I'm still scared, I haven't fought in years, and I don't know how far your level has dropped. ”

"Phew, my level has dropped? Look at your belly, can you still get on the plane?"

Meng Shu ignored the mouths of those people, and said with a flat expression: "It seems that this turbojet engine is still too fuel-hungry......

"Yes, Mr. Meng, even the latest turbojet V, axial turbojet engine we are using now, its fuel consumption is not ideal. Until turbofan engines are practical, this is the only way to reach supersonic speeds. Cheng Fei's chief engineer said helplessly.

At this time, Jin Hai said: "Mr. Meng, several aircraft this time are already very mature, when will the troops be equipped?" He asked the voice of most people, and everyone was waiting for the boss of the air force to answer this question.

It has been almost ten years since the first jet testing machine made its maiden flight on January 11, 1924. From jets to models, it has also changed several times. In 1926, the 1024 test aircraft broke through the sound barrier for the first time and achieved the first supersonic flight in the original plane. And this time the test of more than twice the speed of sound.

Wen Desi is a person who likes mature products, so he can't look down on all the models he has done before, even if his subordinates are so anxious that they scratch their ears and cheeks, he is not in a hurry at all. It is just to 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 enough to use, and China has enough time to perfect its weapons.

....................................................................................

At this time, the three test planes in the sky have all dropped below the speed of sound, but their speed is still maintained at about 800 kilometers, which is difficult for traditional piston propeller aircraft to achieve.

All three aircraft were not the same in appearance and flew the fastest, reaching 2. Mach 7's No. 6605 test machine is a product of Chengfei, with a single-wing configuration on its twin vertical tails, which looks somewhat like the MiG-25 "flying fox" of the Soviet Union in the original time and space. That's right, it's the famous flying stainless steel.

The second fastest is Guangfei's No. 6805 test machine, which looks a little like a magnified circle of "Air Cai Xqing", which flew to 2. Mach 5...... Finally, the No. 6705 test aircraft produced by Efei, which looks like the F-4 "Ghost" of the original time and space, flew to 2. Mach 4.

Well, their dimensions, empty weight and other data are not too similar, and the engines used are also the same, they are all twin-engine heavy fighters, which are considered fighters of the same class. Of course, there are no weapons now.

"I said Dabao, this thing is not suitable for your land aviation, you just have to play, don't be too fascinated. There was a sour sound from Wei Dabao's headphones.

This guy is Brigadier General Hua Gaimu of the Air Force, and he was a step slower just now, and he couldn't grab the fastest test plane No. 6605, and in the end he could only choose the slowest test plane No. 6705.

Wei Dabao, who took the lead in getting the "god machine", didn't care about this kind of little jealousy at all, and said very casually: "Where is it not suitable? I think it is very suitable for our land aviation, you look at the sonic boom just now, what a bull fork." If you fly around the enemy group at low altitude, it will be more effective than a bomb......"

"Phew, Dabao, you kid is whimsical, even if you have the ability to dare to play supersonic at a low altitude, and if you don't have an accident, your superiors won't be able to spare you!" The voice of Major General Chu Wangyuan, the test pilot of test aircraft No. 6805, came from the channel.

The three test pilots are all generals, one major general and two brigadier generals, and now there are a bunch of generals in the command tower who are ready to be test pilots, and each plane can have a dozen reserve test pilots, and the lowest are brigadier generals. This is probably the highest-ranking test pilot team in history, and of course they are only part-time.

"This plane is good, I will suggest when I go back, we must first install ...... for the land airline," Wei Dabao said.

Hua Gaimu said disapprenously: "I said, you army aviation want a hairy fighter, it would be good to have an attack plane." Even if it's fighter support, just call our Air Force. ”

"Cut, when your Air Force plane arrives, the daylilies will be cold, okay, it's not without precedent...... Wei Dabao shot back unceremoniously.

Coordination between the services has always been an issue, at all times. The strange relationship between the old Japanese army and navy was a special case, not to mention it, no matter how good the relationship between the services and the communication conditions were good, there would still be problems. For example, in the U.S. military in the original time and space, the third-class people were often accidentally bombed by the first-class and second-class people, and in many operations, more third-class people were killed by the first-class and second-class people than by the enemy.

Wen Desi, who came from later generations, was too aware of this drawback, so China's army has its own aviation force, not only helicopters, but also fighters to attack aircraft and light bombers, but it is not equipped with large and medium-sized bombers and strategic transport aircraft.

The three test planes quickly returned to the airport, both of which are the elite of the Chinese pilot elite, the top ten masters in the national ace card, and this kind of test flight is not difficult for them at all.

As soon as they stepped off the plane, a large group of ground crew pounced and towed the plane into the hangar for inspection. At the same time, a large number of factory technicians also came over to extract various data.

"What? Not equipped this time?" As soon as the three general test pilots entered the control tower, they were treated with cold water. They all feel incomprehensible, why not use such a good thing?

"What, do you think this kind of thing is good?" Meng Shu said disdainfully: "You guys, Too young, too simple, these things are nothing at all......

Seeing that these guys were still unconvinced, Meng Shu had no choice but to explain: "If it was a war year now, we would definitely be like this." But it is a time of peace, and there is no sign of a major war in the years that can be expected. In the event of a skirmish, our turboprop fighters in service are already fully capable of coping, so why waste resources on such things that will become obsolete in a few years?"

"So, when will the next generation of fighters be installed?" someone asked.

"This central government has taken a holistic view, so please be patient. I can promise you won't have to wait too long......"

........................................................................

Hangar.

There was a bunch of people in front of the flying No. 6605 test machine, and several engineers were checking back and forth with test instruments, and from time to time a data was released, which could arouse applause from the audience. This group of people are all technicians from the three manufacturers, and they are all discussing passionately at this time.

"This new material is really good! It can withstand high temperatures above 400 degrees Celsius for a long time without losing much of its strength......

"The most important thing is that it is very light, lighter than aluminum alloy! It has the strength close to titanium alloy and high temperature strength, but it is lighter than aluminum alloy, which is simply the most ideal material for the aviation industry!"

"Hey, it's a pity that it's a little more expensive, although it's cheaper than titanium alloy, but it's still more than twice as expensive as aluminum alloy......"

"In fact, [B-shaped porcelain steel] is also quite suitable as an aviation material. If it weren't for this kind of [Mithril], we could also choose B-shaped porcelain steel, which is a little heavier, but cheaper......"

The [B-shaped porcelain steel] they said is also the B-type iron and aluminum alloy, and now in order to confuse the outside world, all kinds of new alloys launched during this period have been given a very nickname. The two iron-aluminum alloys are called A-type and B-shaped porcelain steel, and Mithril is the body material on these three planes today. There is also a kind of [Adamantite], which is an armor material.

In the history of human aviation, when airplanes broke through the sound barrier, began to move towards Mach 2. By the time 5 or more is launched, a whole new obstacle has begun to cross in front of the humans. This is the "thermal barrier" caused by the high temperature caused by the sharp friction between the body and the air molecules in high-speed flight. When the aircraft is flying at Mach 2 speed, the surface temperature of the fuselage has reached 107 degrees Celsius, and when the aircraft continues to increase the throttle towards Mach 2. 5. When sprinting, the surface temperature of its body will reach more than 200 degrees. And according to calculations, if the aircraft reaches Mach number 3, then the surface temperature of its fuselage will reach 300 degrees!

High temperatures can bring a series of troubles. Generally speaking, the material of the aircraft body is aluminum alloy, even if it is a high-strength aluminum alloy, its melting point is only 400-500 degrees Celsius, and at a high temperature of 300 degrees, the traditional aluminum alloy skin material will become more fragile than paper, if coupled with the huge speed pressure brought by high speed, then the body at this time will be deformed or even disintegrated.

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 time and space were manufacturing the MiG-25, their titanium alloy processing ability was very weak and could not be made into a qualified body, so they opened their minds and played with stainless steel aircraft. This is also the origin of the nickname "flying stainless steel".

However, China on this plane is not so embarrassed that it will use stainless steel to make airplanes, and Wen Deji has better materials in his hands, and there is more than one. With China's processing capacity on this plane, of course, it is no problem to make titanium alloy aircraft, but there are better and cheaper materials, why not use them?

Porcelain steel is actually prepared for battleships, chariots, cannons, and other things, mainly because these weapons are used more. Of course, he will not forget the airplane, he prepared another new alloy for the aircraft - "magnesium sodium alloy", this kind of use of mythical legendary metal as a nickname is extremely unrealistic.

Its specific gravity is about half that of aluminum-magnesium alloy, only 1. 28. The strength is slightly lower than that of titanium alloy, higher than that of stainless steel, and much higher than that of porcelain steel; and the strength at high temperature is slightly lower than that of titanium alloy, but it can fully withstand the aerodynamic heating effect of the fighter when flying at high altitude at Mach high speed.
