NO. One Hundred and Seventy-Eight Hypersonic Aircraft

? "this way please."

Mark and the others walked towards the dark tunnel ahead, explaining to Zhang Heng the various functions of the aerodynamic department of the academy. It seemed that they had been refrigerated for too long and wanted to show it to the new leaders. , and hopefully it will be reused in the future.

Soon, the tunnel came to an end, and when he walked out of the tunnel, Zhang Heng couldn't help but flash a hint of surprise.

This is an extremely huge space, like a building in the shape of a 'hui', surrounded by rooms, and a square hollow in the middle, which is empty.

Standing at the railing and looking down, this hollow is nearly 100 meters high, and there are more than 20 floors below. The equipment and lights at the bottom are even like ants. Looking up, there are more than a dozen floors. exist.

"This is the assembly hall, and all the flying devices are manufactured from here." Mark said proudly, "and the top of the head here can also be opened. If you are making rockets, you can directly lift off from here."

"Rocket?" A flash of surprise flashed in Zhang Heng's eyes, "Can you send satellites to the sky?"

"Theoretically, it is possible, but unfortunately, there are not so many resources for us to squander." Mark's eyes showed regret, "At least we need to gather the human and material resources of the entire Boston, in order to concentrate enough resources to send the satellite to the sky. ?"

Zhang Heng nodded, just keeping these secrets in his heart, instead of talking more about this issue, he changed the subject and said, "Is the new aircraft at the bottom?"

"Yes, please come with me." Mark walked Zhang Heng around the edge of the 'hui'-shaped building, and quickly walked to an open elevator, "Please come in."

Zhang Heng stepped onto the elevator in one step, then Adam and Gu Zhan also stepped on, and finally Mark stepped on, but the scientists behind Mark did not keep up. After all, the elevator has an upper limit. If they want to keep up, they have to wait. There is an elevator.

The elevator slowly went down, and soon, Zhang Heng could clearly see a long, shuttle-shaped metal object the size of a medium-sized bus in the center of the hall, and there were four propeller-like objects on both sides of the metal object.

"That's a new type of fighter aircraft based on the blueprints you brought - the Falcon fighter series." Mark pointed to the cigar-like spaceship and sighed, "Since the Enclave gained absolute advantage with the Bird helicopter, That kind of stupid bird can already be said to be a big killer in the world. The nuclear war broke out all over the world, and the overall industrial level of human beings has declined for hundreds of years. Although it has rebounded later, it is difficult to return to the pre-nuclear war. of ever-increasing standards.”

"In fact, the level of technology has continued to decline over the years, and it is estimated that in a few hundred years, humans are likely to return to the Stone Age of slash-and-burn farming.

"Mark sighed, but his expression immediately showed relief, "until I saw the design drawing you sent, its technological content is not much higher than that of the Bird Helicopter, but the application skills are several times higher. In this era, I really can’t imagine that those familiar technologies can still be applied in this way. I am really relieved to see this kind of technology, it makes me feel that the fire of mankind has not been extinguished, and mankind still has a future and hope…”

Zhang Heng listened politely at first, but when he listened to it, it felt a little strange.

This Mark, shouldn't it be a chatter?

In this way, in the sound of Mark's continuous explanation, the elevator descended to the first floor of the hall, and Zhang Heng could finally observe the Falcon fighter aircraft that will be used in the mission at close range.

The Falcon fighter has a shuttle shape as a whole. Because it is an aircraft in the atmosphere, it is very important to maintain a streamlined shape. Every line on the surface of the Falcon fighter perfectly reproduces the perfect combination of aerodynamics and art, so that the whole aircraft shows a strong of beauty.

The Eagle Falcon fighter does not have any door and window structure, only the tail has an inclined entrance and exit. The entrance and exit are closed during flight. Only after landing, the tail entrance and exit baffles will be lowered to form a slope leading to the ground.

Zhang Heng walked around the Falcon fighter, and Mark on the side continued to explain in a sighful tone, "Did you see it? The whole plane does not have any components such as wings, only the left and right sides of the fuselage. It consists of two embedded ramjet engines and four movable ion lift fans the size of a basin."

"The style of the Falcon fighter is a reflection of the principle of maximizing efficiency. It doesn't even have an observation window. There are only two control helmets in the interior cockpit. The pilot and co-pilot will directly put on the helmets to control the fighter."

"The Falcon is 9.88m long, has a wingspan of 2.5m and a height of 3.3m. It is made of high-strength titanium alloys, has a built-in nuclear fusion battery, has a load of 10 tons, and has a maximum thrust of 1,200 kN!" Mark said, his eyes gradually revealed Fanatic, "The weapon system is two built-in laser Gatlings, and four built-in magazines that can carry four laser-guided Fat Man nuclear bombs."

"Are there no air-to-air missiles?" Zhang Heng frowned.

"Do you think you need it?" Mark laughed, "In addition to ballistic intercontinental missiles, what missiles can be faster than the Eagle Falcon itself?"

Zhang Heng raised his eyebrows, "You mean, the Eagle can fly faster than Mach 6?"

Facing Zhang Heng's questioning, Mark became even more excited. He looked at the aircraft in front of him with a frenzy, "Because even the ion lift fans and magazines are built-in, so the whole fighter has no extra parts, just like It's a cigar with a thick center point...so its top speed is..."

"Mach 13.5!"

Zhang Heng's expression froze, and he couldn't believe it, "What? Can it really approach the speed of a ballistic missile?"

"Your Excellency Commander, I must be honored to inform you..." Mark Gravity nodded, "Yes! Strictly speaking, the Eagle Falcon is no longer a fighter jet. It does not belong to the category of fighter jets, but to the category of hypersonic aircraft! "

"It is said that even in the era of the highest peak of human civilization, the hypersonic aircraft made by human beings only use the method of gliding, relying on ramjets to enter the state of hypersonic flight from an altitude of tens of thousands of meters, while your Falcon fighter jets No need at all! It takes off and lands vertically with four ion lift fans, then accelerates to supersonic speed with the jet of high-intensity particle flow, and then boosts it to a dozen times the speed of sound with the ramjets on both sides!"

A flash of surprise flashed in Zhang Heng's eyes. He really didn't expect the aircraft designed by Yuehua to be so powerful, but fortunately he occupied the academy, otherwise Yuehua would have become a clever woman who would be hard to cook without rice. However, as if thinking of something, Zhang Heng continued to ask, "What about driving, how is the difficulty of driving skills?"

"Your Excellency Commander, the driving skills are very simple. Adam and I both know how to drive, but we have been simulating driving in the wind tunnel, and have never been flying in actual combat." Gu Zhan interjected at the right time.

"Very good!" Zhang Heng couldn't help but snapped his fingers, his expression loosened, and it was enough to drive in the wind tunnel, which means that it should not be much worse in reality, but for the sake of insurance, Zhang Heng still ordered Mark to assemble the hall. The ceiling is opened, allowing Adam and Gu Zhan to conduct several more actual combat flight training, because tomorrow is the time to experience the next plane mission!

For the next plane task, Zhang Heng has already decided to choose the plane with half-star difficulty - "Deep Space Amnesia". (To be continued.)
