Dragoon fighter

"Go over there and you're not allowed to board the plane!"

The signal-flag special forces soldier still looked with distrust in his eyes, Chinese!

Even if he is a member of the Sukhoi Company, he is still suspicious. Within the scope of his duties, not even a fly can fly over.

In fact, this is indeed the case. There are several bottles of insecticide in the nearby toolbox. With modern technology, it is not surprising that detection chips are installed on the flies.

Regarding the dedicated behavior of the Russian special forces, Lin Mo expressed understanding and smiled at the other party, nodded, and then followed the others.

Su-47, codenamed "Golden Eagle", adopts avant-garde forward-swept wings as its biggest feature. It is produced by Russia's Sukhoi Experimental Design Bureau Open Joint Stock Company. As a multi-purpose fighter, it is also Russia's fifth-generation fighter. The production cost of the technology verification machine is no less than US$50 million.

As the first prototype, it originally used the D-30F6 engine, but now it has been replaced with a twin-engine al-41f turbofan propulsion engine. The wings use fusion technology, and 90% of the structural components are made of composite materials, with consistent strength. The most important thing is the forward swept wing. That is to say, Lin Mo has the help of the golden dragon to have enough confidence to use the forward swept wing structure.

The wing root extends backward to the tail to form a horizontal stabilizer. The leading edge is swept back at an angle of 70 degrees. The twin vertical tails are tilted outward about 6 degrees. The leading edge is swept back at 45 degrees. There is a built-in rudder.

Compared with conventional fighter jets, the Golden Eagle's turning angle speed can be increased by 14%, the aircraft's radius of action can be increased by 34%, and the takeoff and landing distance can be shortened by 35% to 50%. It has good low-altitude, low-speed maneuverability and super maneuverability. , the combat parameters are no less than those of the F-22 "Raptor".

With the forward-swept wing design, super maneuverability is its biggest advantage.

Like admiring a piece of exquisite art, Lin Mo's right hand touched the surface of the aircraft. This opportunity for close contact was very rare, and it was only because of Lin Mo's promise to help Sukhoi with the Su-27 transition. Lin Mo was allowed to get close to the "Golden Eagle".

If anyone can touch it, after an exhibition, the skin of the fighter jet will not be directly polished with fingerprints by the hands of tourists, and it is the top-level polishing, and even the painting will not be retained.

During the contact, the fragments of the gold-type dragon and gold coins found an opportunity to infiltrate and began to analyze and scan the structure and design of the fighter jet. Neither the Sukhoi Company nor the Russian military knew that their "Golden Eagle" The real secret is being revealed bit by bit in front of the dragon knight from this other world.

The dark green coating has a very smooth surface. According to feedback from gold coins, the wing part uses a large amount of high-strength composite materials. From the installation traces, it seems that it is not the original material, but an advanced nano-material that has been upgraded once or twice. , which can not only improve the tolerance of fighter jets in supersonic environments, but also improve the stealth performance that is weakened by the shape and reduce wing tip tremor.

However, the maximum speed of the "Golden Eagle" can only reach Mach 2, but this is already the limit. Unlike ordinary fighter jets, it can even go a little higher. In fact, when it exceeds Mach 1.6, it will withstand greater vibration and vibration than a swept wing. The life of the forward-swept wing under pressure will accelerate aging. If it is accelerated at all costs, the "Golden Eagle" is likely to become a one-time suicide missile.

When radar waves are irradiated frontally, the acute angles and convergent reflection angles produced by the forward-swept wings will enhance the radar echo and seriously affect the stealth performance. Sukhoi's solution is to use non-metallic materials.

Sukhoi solved the problem, but it caused problems for gold coins. This guy is a natural nemesis of metals, but he cannot digest non-metallic composite materials. He can only wander around the surface of the skin and detect the internal metal frame structure. Wings However, the body's materials are powerless. After a while of hard work, he can only explore the inside of the body.

"Well, S-37 is the pride of our Sukhoi!" When talking about the "Golden Eagle", Sukhoi's senior engineer Sergey Sulotov looked proud.

The S-37 mentioned in his words is the internal engineering research and development number of the Su-47 "Golden Eagle" at Sukhoi Company. Only internal personnel of Sukhoi Company will call the "Golden Eagle" S-37. This s is not the first letter of sukhoi, but refers to the forward swept wing.

A similar example is the Su-27. The engineering research and development number is t-10, and t means delta wing.

"It is indeed a good aircraft!" Lin Mo valued more the leap-forward improvement produced by the combination of materials and aerodynamic design. He walked around the "Golden Eagle" with his hands on the fuselage.

Seeing Lin Mo touching the canard of the "Golden Eagle", engineer Sergey Sulotov followed his movements and said: "This is a canard design. Although it solves the problem of lift trimming and improves maneuverability , but this is just a compromised technology, it is not a good combination with the forward-swept wing, and the stealth performance is not perfect."

"Yes."

As a retired expert from the 611 Institute specializing in aerodynamic design, Lin Mo nodded and agreed with engineer Sergey Sulotov's opinion.

As a professional, you can even judge the performance, advantages and disadvantages of the aircraft body based on its appearance and aerodynamic layout.

He finally let go of his hand, and the metal wire hidden in the "Golden Eagle" returned between his fingers, interlocked end to end, and turned into a silk ring covering his little finger joint.

Although the composition of some non-metallic composite materials cannot be known, Lin Mo already knows the parameters of the cockpit design and functional modules that cannot be seen with his own eyes, as well as the parameters of the entire body.

As long as it is made of metal, the metal dragon can see things down to the micron level without any reservations.

"Let's go and take a look at our Su-27! It's an absolutely great model. It is also the main export model of our country's fighter jets. It is not inferior to the MiG-29."

Engineer Sergei Sulotov was very interested and took Lin Mo to see the Su-27s.

While they were watching the "Golden Eagle", the flight crew from the same bus had already begun preparations for body inspection before takeoff, and called the airport's refueling truck.

Compared with the MiG, it started to go downhill.

There is an upward trend, and Sukhoi, who won the Russian fifth-generation fighter T-50 project, has shaken off the depression that the majority of Russian fighter export orders were taken by the MiG-21, and feels quite proud.

Lin Mo carried his luggage, took back his watch from the signal flag special forces, and fastened it on his left wrist again, and everything returned to its original state.

No one knows that in just a short period of time, most of the secrets of the Su-47 "Golden Eagle", the pride of Sukhoi, were stored in this small watch.

Seven Su-27 "Flankers" were lined up in a row and parked quietly on the apron. At this moment, they had unlocked the front wheel locks and removed the blocking triangle blocks of the front and rear wheels of the landing gear.

The mechanics brought by Sukhoi were divided into three groups of two, and they conducted pre-takeoff inspections on the seven fighter jets in turn.

Due to the short flight range, there is no need to even mount a fuel tank. Just replenishing the built-in fuel tank is enough to fly to the destination.

"Hi! Hi! Guys, do you have any extra anti-Dutch suits?" Engineer Sergei Sulotov clapped his hands and asked loudly to the six Russian Air Force pilots who were preparing.

Since he called Lin Mo for help halfway, he did not bring an extra set of anti-German suits. Although it was such a close distance, it was not a combat flight. Wearing or not wearing anti-Ground suits was not a big deal, but safety still came first. of.

Pilots will be subject to overload forces in six directions in the air. The overload force that has the greatest impact on safety is the overload force from head to toe. Especially when the overload force reaches a certain level, it is easy to cause cerebral ischemia, hypoxia, visual impairment, and even visual impairment. Loss of consciousness can lead to aircraft crash and death. Good-quality anti-G suits can reduce the probability of pilots experiencing red vision or black vision and reduce physical damage.

Almost more than one fifth of pilots have experienced overload leading to loss of consciousness, so this is also the biggest threat pilots encounter in flight.

"Sorry, Mr. Sulotov, we only brought one set ourselves and don't have any extra. Why don't we find some bandages or cloth tape to wrap it up?"

A Russian Air Force pilot who was putting on a Dutch-resistant suit with the help of his comrades spread his hands and shrugged, saying that he could not help. Indeed, few people would prepare two sets of Dutch-resistant suits. After all, this is a flight-specific suit, not a garment for daily wear.

However, he still proposed an emergency plan when there is no anti-German suit.

The most commonly used anti-gravity suit in the world adopts a five-bag design, which can cover most of the abdomen and lower limbs after being worn. By cooperating with the anti-gravity high-pressure device on the aircraft, gas is automatically input into the anti-gravity suit according to changes in overload force, and the Mechanical pressure is exerted on the surface of the human body to tighten the pilot's abdomen, thighs, and calves to prevent blood from moving downward, ensuring the blood supply to important organs such as the human heart, brain, and eyes, and effectively improving the pilot's load-bearing endurance.

The emergency plan provided by the Russian Air Force pilot also directly wrapped the human abdomen and legs with bandages and directly applied fixed mechanical pressure. Although there is no way to automatically adjust the pressure like a real anti-gravity suit, it can at least provide low overload in short distances. When maneuvering, it can barely be used.

This method is not an idea thought up by the pilot himself, but has been applied for a long time and has certain feasibility.

After the establishment of the first aviation school of the Communist Party of China, there were no special flight suits, so the clothes of the flight students could only be tied with hemp ropes. This ensured that the first generation of Chinese pilots could fly into the sky.

"Ah? Bandage? How can this be done? Why don't we bundle it up into a mummy? No, no? Can anyone help me borrow it? Borrow it from the French Air Force and return it immediately." Sergey Sulotov was so anxious that he was anxious. , the advice provided by domestic pilots is really out of tune.

ps: Monthly passes are collected for this month, hurry up and give them.
