"This way, please. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ”

Mark and the others walked towards the black hole tunnel in front of them, explaining to Zhang Heng the functions of the pneumatic department of the academy as they walked, it seemed that they had indeed been refrigerated for too long, and they desperately wanted to show it in front of the new leader, hoping that they could be reused in the future.

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

It is an extremely large space, like a building in the shape of a 'hui', surrounded by rooms, and in the middle is a cube hollow, empty.

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

"This is the assembly hall, from which all the flying gear is made." Mark proudly said, "And the top of the head here is also openable, if you are building a rocket, you can directly lift off from here." ”

"Rockets?" A flash of surprise flashed in Zhang Heng's eyes, "Can you send a satellite to the sky?" ”

"Theoretically, yes, but unfortunately, there aren't that many resources for us to squander." Mark had a look of regret in his eyes, "At the very least, we need to gather the manpower and material resources of the whole of Boston to concentrate enough resources to send the satellite into the sky, right?" ”

Zhang Heng nodded, just kept these secrets in his heart, and didn't talk more about this issue, but changed the topic and said, "Is the new flying machine at the bottom?" ”

"Yes, please come with me." Mark took Zhang Heng to walk around the edge of the 'Hui' shaped building, and soon walked to an open elevator, "Please come in." ”

Zhang Heng stepped onto the elevator one step at a time, 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, and if they want to keep up, they can only wait for the next elevator.

The elevator slowly descended, and soon, Zhang Heng could see a medium-sized bus-sized, long shuttle-shaped metal object in the center of the hall, and on both sides of the metal object, there were four thrusters-like things.

"That's a new type of fighter based on the blueprints you brought, the Eagle Falcon series." Mark pointed to the cigar-like spaceship and sighed, "Since the Enclave relied on the Bird helicopter to achieve absolute superiority, that kind of stupid bird can be said to be a big killer across the world, the world's nuclear war broke out, and the overall industrial level of mankind has declined for hundreds of years, although it has risen some later, but it is difficult to return to the level of continuous improvement before the nuclear war." ”

"In fact, the level of science and technology has been declining over the years, and it is estimated that in a few hundred years, human beings 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 you sent, its technology content is not much higher than that of the Flying Bird Helicopter, but the application skills are several eras higher, I really can't imagine, those familiar technologies can still be applied in this way, I am really very pleased to see this 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 there was something wrong with listening.

This Mark, it can't be a chatter, right?

In this way, amid Mark's gushing explanation, the elevator descended to the first floor of the hall, and Zhang Heng could finally observe the Eagle Falcon fighter that was about to be used in the mission.

The Eagle Falcon fighter is a fusiform as a whole, because it is a vehicle in the atmosphere, so it is important to keep it streamlined, and every line on the surface of the Eagle Falcon fighter perfectly reproduces the perfect combination of aerodynamics and art, so that the entire aircraft shows a strong sense of beauty.

The Eagle Falcon fighter does not have any door and window structure, only the tail has an inclined entrance, the entrance and exit are closed when flying, and only after landing, the tail entrance and exit baffle will be lowered, forming a slope to the ground.

Zhang Heng walked around the Eagle Falcon fighter, and Mark on the side continued to explain in an emotional tone, "Did you see it? The aircraft does not have any wings or the like, only two inline ramjet engines on the left and right sides of the fuselage, and four movable ion lift fans the size of a washbasin. ”

"The style of the Falcon is a manifestation of the principle of maximizing efficiency, it does not even have an observation window, and there are only two control helmets in the cockpit inside, and the pilot and co-pilot will directly put on the helmets to control the fighter."

"The Eagle Falcon fighter is 9.88m long, with a wingspan of 2.5m and a height of 3.3m, made of high-strength titanium alloy materials, with a built-in nuclear fusion battery, a load of 10 tons, and a maximum thrust of 1200 kN!" Mark said, his eyes gradually revealing fanaticism, "The weapon system is two built-in laser Gatlings, and four built-in magazines, which can carry four laser-guided fat nuclear bombs. ”

"Aren't there any air-to-air missiles?" Zhang Heng frowned.

"Do you think you need it?" Mark laughed, "Aside from ballistic ICBMs, what other missile can be faster than the Eagle Falcon itself?" ”

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

In the face of Zhang Heng's questioning, Mark became even more excited, and he looked at the aircraft in front of him with a fanatical look, "Because even the ion lift fan and bomb magazine are also built-in, so the whole fighter does not have any superfluous parts, just like a cigar with two tips and a thick middle...... Therefore, its top speed is ......"

"Mach 13.5!"

Zhang Heng's expression froze, and he was also a little incredulous, "What? Can it really approach the speed of a ballistic missile? ”

"Your Excellency, I must be honored to inform you...... "Mark Gravity nodded, "Yes! Strictly speaking, the Eagle Falcon is no longer a fighter, it does not belong to the category of fighters, but to the category of hypersonic vehicles! ”

"Legend has it that even in the era of the highest peak of human civilization, the hypersonic aircraft built by human beings only used gliding, relying on ramjet engines to enter the hypersonic flight state from an altitude of tens of thousands of meters, and your Eagle Falcon fighter did not need to do it at all! It relies on four ion lift fans to take off and land vertically, and then relies on the high-intensity particle stream of jets to accelerate to a supersonic state, and then increases to more than ten times the speed of sound in one fell swoop with the ramjet engines on both sides! ”

A flash of surprise flashed in Zhang Heng's eyes, he really didn't expect the flying machine designed by Yuehua to be so powerful, but fortunately he occupied the academy, otherwise Yuehua would have become a clever woman who would be difficult to cook. However, as if thinking of something, Zhang Heng continued to ask, "What about driving, how difficult is the driving skills?" ”

"Your Excellency, the piloting skills are very simple, Adam and I can both fly, but we have been simulating piloting in the wind tunnel, and we have not done actual combat flights." Gu Zhan interjected at the right time.

"Good!" Zhang Heng couldn't help but snap his fingers, his expression was relaxed, it was enough to drive in the wind tunnel, which meant that it should not be much worse in reality, but for the sake of insurance, Zhang Heng still ordered Mark to open the ceiling of the assembly hall and let Adam and Gu Zhan conduct a few more actual combat flight training, because tomorrow is the time for him to experience the next plane mission!

For the next surface task, Zhang Heng has already decided, so he will choose the plane of half-star difficulty - "Deep Space Amnesia". (To be continued.) )
