Coquettish Rebirth

To be honest, this is not a call from a military worker, but a conference call with a group of military workers that Mr. Ye found!To put it bluntly, this matter is a bit like bidding!The first person to speak first was the chief designer of an aircraft design institute in Southwest Shudu—"I heard Mr. Jia, you need a private jet? Even a supersonic one? Can you tell us about the specific requirement?" Is it? I am from the 6x1 Institute in Shudu, and the person next to me is from the Design Institute in Chang'an."

"Okay, that's it. Simply put, I want a supersonic airliner similar to the Concorde, but it is small, with about 20 people on board. The interior space is relatively large, and the overall length is about longer than that of a fighter jet—— The su27 is long, and it can be equipped with entertainment facilities, bathrooms, conference rooms, satellite phones, and guest rooms where you can sleep... By the way, it is best to have a cruising speed of Mach 2!"

After Jia Hongjian finished speaking, after listening to the two chief designers discussing for a while, he answered him like this - "According to some parameters of foreign business jets given to us by Mr. Ye, the current civil aircraft It is almost impossible for the engine to provide the speed you need. You see, this Concorde is the only civilian engine that has afterburner. It was originally designed for military bombers, and this engine is a bit outdated. , it uses a turbojet, that is, a turbojet engine. Nowadays, the engines of foreign civil airliners are basically turbofans, turbofan engines, and turbofans are more fuel-efficient than turbojet... So, even if you buy the most advanced civilian engines abroad. Four of them on your plane may not be able to fly to the speed of m2, which is Mach 2, because the thrust of a single civil engine is not as good as that of the military, and the single thrust is low, so it needs to reach a speed that can push your plane to twice the speed of sound. A lot of engines are needed, such as four or six. But more engines will consume more fuel, and if more fuel is consumed, the aircraft will need to increase the tank capacity, or even enlarge the entire aircraft to increase the space that can be loaded with fuel. Because you The aircraft has a range of more than 1 kilometers or even [-] kilometers. But after the aircraft is enlarged and refueled, the aircraft becomes heavier... How should I put it, this is a bit like the plight of Germany during World War II. In order to enhance the defense capability and maneuverability, it is necessary to thicken the armor and use a more powerful engine, but thickening the armor and a more powerful engine will increase the weight, then require more fuel, and increase the weight... …This is adding noodles when there is too much water, and adding water when there is too much noodles, and in the end you may not get both sides…”

Just when the designer from Shudu had just said this, the chief designer from Chang’an suddenly interrupted and said, "Ordinary civilian engines are not enough, but what if a ramjet engine is installed? That thing It’s solid. It’s also fuel-efficient, and the faster the speed, the more economical it is. When flying to Mach 3, the thermal efficiency is higher than that of a turbofan! It’s just that the fuel consumption is more...”

"A ramjet engine?" Jia Hongjian didn't quite understand, "It's just a device. How should I put it, it can be seen as something like an elongated horn made of stainless steel. Doesn't this ramjet engine rely on it like a turbofan?" The compressor fan compresses the incoming air, but relies on the original high-speed movement, allowing the air to hit the horn-shaped engine wall by itself, pressurize itself, and wait until it can burn. Basically, it will become a pressure of more than 20 atmospheres , the temperature itself can be as high as 1000 degrees, and then the fuel injection ignites at this time, causing air deflagration, and then the volume expands, which can push the aircraft forward. This thing can be said to be the predecessor of the jet engine. It is very primitive, but Works great too. The only problem is, the thing basically won't start at Mach [-]!"

"However, it is possible to design a combined ramjet engine. For example, install two civilian engines, first push the aircraft to a speed of about Mach [-], then turn on the ramjet engine and turn off the normal engine. When the destination is approaching, turn on the normal engine , turn off the ramjet engine..." the designer at Shudu suddenly added!

"Yes! Good idea, and Mr. Jia, our country designed a target drone in the 60s. The engine used in that target drone is a ramjet engine. It can fly up to Mach 3, which is three times the speed of sound! Our target drone The aircraft imitated the high-altitude and high-speed reconnaissance aircraft of the United States and the Bay! It was used to practice how to hit the reconnaissance aircraft of China, the United States and Taiwan for our anti-aircraft missiles! According to the design plan, we changed it and installed two ramjet engines on the business jet. The belly should be fine, it looks just like the Concorde."

"However, when the civilian engine is flying at Mach two or three, will the structure itself cause a lot of air resistance? If it doesn't work, just combine the two together? Make a fuss about the air inlet and make it into an integrated combined turbine The ramjet engine, just like the American SR-71 Blackbird reconnaissance plane, cooperates with the bypass damper to treat the entire turbojet engine as a compression hood? But it can be done, and the problem is not big, it’s just that the high temperature is not good Get it right, the 2m speed can barely use aluminum alloy, and the aluminum alloy can’t help if the speed is a little faster. For example, the American Blackbird reconnaissance plane can fly to Mach 25, and they will use a titanium alloy fuselage. After all, it is hot The obstacle is...or is it made of all stainless steel like the MiG-25?" At this time, the chief designer at Shudu suddenly said, "The Soviet MiG-[-] can also double three, and the altitude of [-] meters and Three times the speed of sound, and then we still have MiG designers in our design bureau..."

Jia Hongjian has heard a little about this MiG 25. The code name of this MiG 25 in NATO is "Fox Bat". It is said that it was developed to deal with the US SR-71 reconnaissance plane.Because the American planes fly too high and too fast, not to mention that ordinary planes can catch up, even if they launch missiles, they can't hit them. In those days, missiles flew faster than other planes!Later, the Soviet Union launched the MiG-25 aircraft in the surprised eyes of the world. This interceptor can easily fly to an altitude of 2.8 meters, and then leisurely follow behind the SR-3 at a speed close to Mach 71, warning the other party not to Fly around!

This year terrified the Americans!You must know that the Americans always felt that they were advanced in technology at that time. They spent a lot of effort and finally got some titanium alloys to make SR-71. As a result, the Soviets also got titanium alloys to make a volley so quickly. machine out?This proves that the Soviets also mastered the cutting and shaping technology of titanium alloy?The Soviets are too good?

It was even later said that when the Soviet Union deployed this MiG-25 to the Middle East and Soviet pilots flew the plane instead of the locals, they "accidentally" flew over Israel.Then the pilots in the se line quickly drove the plane and chased him, only to see that the other party was a model that he had never seen before, and he was not obedient and would not run away!At that time, the pilots of the Israeli column fired missiles immediately after asking for instructions. As a result, he was horrified to find that the plane in front of him kept spouting fire from behind his buttocks, and then disappeared in the blink of an eye. The missile flying forward is like a great irony!

At that time, the MiG-25 was said to have brought great fear to Americans and Europeans. They felt as if the Soviets had obtained alien technology!As a result, in 76, a Soviet pilot defected to Japan with a MiG-25. When the American military personnel disassembled the aircraft with great expectations and inspected the "titanium alloy" body, suddenly The glasses fell all over the floor——Nimma, when Americans spent a lot of money to process titanium alloys in order to break through the thermal barrier, the Soviet boss actually used ordinary stainless steel to make airplanes?Also flew this plane to Mach 3?This fucker makes people's brains almost freeze up!And this stupid product, not only the aircraft is made of stainless steel, but even the engine is made of stainless steel!Just to be able to adapt to high speed and high temperature!Although such an aircraft breaks through the speed of Mach 3, the engine will be scrapped within an hour, but it is still very good...

Soon, under the discussion of the chief designers on both sides, a very strange aircraft design concept was released - Jia Hongjian's special business jet will use old turbojet engines, which can be imported or domestically produced. Body skin all stainless steel design.The whole aircraft is very slender, looks like a cut pencil, and then has a large swept-back delta wing, with two huge engines on both sides of the delta wing.Then there are two vertical tails on the engine bulge... The general image of this plane looks like the illegitimate child of the Concorde and the SR-71 reconnaissance plane!And it is said that this aircraft will reach a maximum speed of 2.8 times the speed of sound, a cruising speed of 2.4 times the speed of sound, and a range of at least 6000 kilometers, preferably more than [-] kilometers...

It is estimated that the stainless steel skin will not be very good at painting at that time, it is a shining metallic silver-white, slender, looks a bit like the Blackbird reconnaissance plane and the Concorde, and the ultra-high-speed one can fly at 8000 meters Cruising at more than twice the speed of sound at high altitude, the two pilots need to wear positive pressure breathing machines and wear monster planes like astronauts!If this plane lands at a foreign civil airport, it is estimated that it will be very attractive to others?It is estimated that many Yankees will think that this is a new spy plane developed by the United States?

Well, it sounds very high-profile, not low-key at all... Then Jia Hongjian will wear sunglasses and a hat, so that no one can find out that it is Jia Hongjian who is flying!So low-key!Well, that's right!
