Coquettish Rebirth

What is the aesthetics of violence?This is called the aesthetics of violence!Just like the MiG-25!The stainless steel shell of the MiG 25 flew directly to the speed of Mach 3 directly under the powerful engine, so that the enemy's missiles could not catch up with the fighter jets!It made Europe and the United States astonished, thinking that the Soviet Union had mastered the black technology of alien titanium alloy processing technology, but who knew that the Soviets just used stainless steel in such a stupid way!

"Mr. Jia, this is the chief designer of our aircraft, Lao Song..." Cheng Fei's leader led an old man to come in front of Jia Hongjian and the others.This old Song is the chief engineer of 611, the military aircraft design institute that has a close relationship with Chengfei.The plane this time was designed by Lao Song.

"Mr. Jia, Mr. Su, little Jia, hello." Old Song, whose hair was all white, came up to shake hands with Jia Hongjian and his family.After exchanging pleasantries for a while, this old Song began to introduce the plane, "Our plane uses a turbojet engine plus a ramjet engine. The four oblique rectangles hanging under the wings are the engine compartment... In this way, the entire fuselage of the aircraft can be used as the business class, and even the tail part, and we have also designed a cargo space that can carry cargo within two tons..." Lao Song introduced.

The business jet in front of Jia Hongjian and the others was silvery and extremely slender.The overall length of this aircraft is much longer than the private business jets commonly seen on TV, and it looks particularly sharp!The front of the entire nose is as sharp as a needle!This kind of machine head alone can be known at a glance.This plane is different from ordinary business jets!At the same time, the aircraft starts to have wings behind a door at the front of the cabin, and then the wings go all the way to the tail of the aircraft, forming a huge triangular wing instead of the trapezoidal wing of the usual business jets. Looking at it this way, this plane is also very domineering!At the same time, this aircraft is still a lower wing, which means that the wing is on the plane of the entire aircraft belly.So if you look at it from below.The wings of this plane definitely have the feel of a space shuttle!

Judging from the appearance, this aircraft definitely has a sci-fi mixed with industrial violence beauty. Just as Jia Hongjian was admiring the appearance of the aircraft with admiration, he only listened to Lao Song's introduction. "When our aircraft is cruising and flying at a speed of about Mach 2, the maximum stagnation point temperature of the overall surface is as high as 300 degrees Celsius. The usual aviation aluminum can only reach a temperature resistance of 140 degrees Celsius. Therefore, a different design must be adopted. If you want to use new technology and technology, you may need to use very expensive titanium alloy. Titanium alloy itself is too hard. It is very difficult to process, so the cost is very high. After all, our aircraft is for civilian use, so we don’t need to ignore the cost. , so we adopted the more direct and simple method of the Soviet Union, which is to use stainless steel, but in this way, the overall weight will increase, and the fuel consumption will also increase. However, compared with using titanium alloys, the cost is still reduced A lot..."

"In addition to the welded integral fuel tank of the wing, the welded integral fuel tank structure of the fuselage accounts for 30% of its volume. The weld seam on the fuselage is as long as 4,000 meters, and there are as many as 140 million welding points. The integral fuel tank structure makes the aircraft The total fuel storage capacity is as high as 24.5 tons. It can be said that the business class of our aircraft is actually surrounded by a circle of fuel tanks. During the overall test flight, after our test, it cruised at a speed of Mach 2. The temperature will exceed 1000 degrees Celsius. In order to prevent the high temperature on the shell and parts from entering the cabin, we have designed a special heat insulation layer. This silver-plated heat-resistant partition covers the entire business cabin. In total, we In order to insulate the entire aircraft, a total of 10 kg of silver was used... In this way, the heat absorption of the entire heat insulation layer is 3-5%, and this 3%-5% heat absorption will be absorbed by the glass fiber later. The heat insulation layer blocks a part, basically at the end, according to our test, when cruising at Mach 2 speed, the temperature in the cabin will remain at about 28 degrees Celsius, which is just right without turning on the air conditioner..."

Whoa!What a treat!So, in winter, when flying at an altitude of more than 1 meters, the temperature can still be kept at around 28 degrees Celsius?Then it is enough to wear a T-shirt directly in the plane!As for the various temperature differences when getting off the plane... Isn't this Jia Hongjian's plane?Bedrooms, bathrooms, etc. are also designed inside the plane, not to mention there are dressing rooms, and there are various insulation measures. It can be said that the temperature will not change if the door is not turned on. You can go out after changing clothes inside the plane. Well!How wonderful!

At this time, I only heard Lao Song introduce, "Compared with the conditions of the business class, the cockpit is a little worse. Because the cockpit cannot be completely isolated like the business class, it will still be introduced by the outside temperature. But we A special air nozzle is used to cool down the equipment and personnel in the cockpit. Generally speaking, according to the reports of our test pilots, when the entire cockpit is cruising at Mach 2, the temperature is about 35 degrees Celsius, which the pilots think is acceptable. It’s just that you must wear gloves when operating, otherwise it may cause low-temperature burns due to time manipulation…”

Whoa! 35 degrees working temperature!When Jia Hongjian heard the temperature, Jia Hongjian and his parents subconsciously looked at each other!In this year, the temperature is equivalent to working under the sun in the summer. It must be quite hard work!If the pilot crew does this, it means that as long as they are flying, they are working in the dog days. Why should they be given more high temperature allowances?And fortunately, the flight time from China to the United States is about 5 hours. Otherwise, if the time is longer, the pilot will not be dehydrated?

At this time, Lao Song continued, "In the plane, we adopted the missile attitude control system used in the past, so that when flying, as long as it needs to fly in a straight line for a long time, this system can be turned on to reduce the burden on the pilot. You can completely believe in the reliability. This is what we used in military missiles before. No matter what you say, you must pass the reliability test. According to our statistics, the failure rate is less than [-]/[-], so our crew should not be turned on. Too far away from the cab after turning on the attitude control..."

Huh?Has the attitude control technology on the missile been used on this aircraft?According to Jia Hongjian's understanding, this technology should be all kinds of gyroscopes, inertial navigation, and starlight navigation?Things like GPS navigation are fine for cars, but if these two Mach-flying aircraft do not have the GPS precision navigation of the US military, it will be a tragedy!But...isn't it a little too much force to use the stuff on the missile on the plane?I feel that this thing is not as good as the automatic posture of other people's civil aviation?

Lao Song seemed to have seen Jia Hongjian's family's doubts, so he explained with a smile, "What do you think about the autopilot in civil aviation? In fact, the autopilot equipment in civil aviation is derived from our military missiles. It is derived from the control instrument. In fact, the automatic driving of civil aviation was originally fixed by the gyroscope. Later, with the development of microcomputer automation technology, a modernized automatic driving system was gradually developed on this basis. Now foreign civil aviation The advanced system can use the onboard computer to calculate the best flight route, and then automatically adjust the throttle and various wing surfaces according to the best flight route. After all, our 611 is a military institute, and there is not much research in this area, so we installed it An autopilot system that can only fix routes..."

Hearing what Lao Song said, Jia Hongjian felt that this would be enough!After all, it is a military aircraft design institute, not a civilian aircraft. How can military aircraft use autopilot?After all, the situation on the battlefield is changeable. Is it necessary for the pilot to doze off by the side, and then the plane will fly automatically?Is this really not afraid of the enemy shooting down?So it's normal for people not to study this.It's okay to have something that is almost usable.Anyway, those systems in Europe and the United States also require pilots to keep an eye on them. Isn't this also the same?

On the other hand, Jia Hongjian and the others found three sets of crews to fly this business jet. All of them were military pilots, and each of them came out of military aircraft, and they had only been discharged from the army not long ago. There is nothing wrong with this design, and I am not even picky about the high temperature of the cab-for soldiers, they use weapons whenever they have, so how can they be picky?Otherwise, when the Japanese army invaded China, the Eighth Route Army would not be able to resist the Japanese because they did not have weapons at hand?

In the army, it is to protect the family and defend the country. If the conditions are bad, you can’t pick them up. Although you are discharged from the army now, this is working for the boss and supporting your family. The bad conditions are nothing, isn’t it just 35 degrees?Wouldn't it be enough to drink more salt water?And it's not like a fighter plane that doesn't even have a toilet. This plane is so big, there must be a place to go to the toilet, and the hot spots will be hot in four or five hours!

After the general introduction, this old Song began to take Jia Hongjian, his family and the crew to go into the plane to have a look.This plane is similar to the business jet in the TV. The cabin door is opened directly from top to bottom. After opening, there is a small hanging ladder directly for people to get down.After entering the plane, Jia Hongjian and the others first went to the cockpit to take a look. Inside the cockpit, there were a lot of instruments. At a glance, it could be said that there were all kinds of instruments and buttons on the top and bottom of the windshield. , that makes people dizzy just looking at it!

A little behind the dashboard, there are two positions for the captain and the co-pilot, and behind them, there is a folding chair position, which seems to be reserved for the backup pilot.This cockpit looks similar to other cockpits of this era - anyway, it is not yet the 21st century, and it is estimated that various electronic posture equipment in China have not yet been developed, and there is no need for digital displays on large screens.

Near the door of the cockpit, there is really a small bathroom with a flush toilet inside, which seems to be a small bathroom dedicated to the cockpit.Behind this small bathroom is a compartment door, and when you open it, you will be greeted with a luxurious scene... (to be continued...)
