Under the leadership of Liu Feng, Minister Jiang and several experts followed by him, and a group of people came to Yang Xijia's office.

Although I have seen the relevant data in the research plan sent by the relevant departments, the cold data seen on paper is far less shocking than the one introduced to them by the designer on the spot.

In particular, Minister Jiang, after his shocked expression, stared greedily at the 3D model of the aircraft on the curtain, as if he could immediately manifest this thing.

Based on his requirements for Huaguo's strategic bombers as the head of the Air Force Equipment Department, if this thing can really be built, it will indeed surprise everyone as Liu Feng said, no, it is terrifying!

"In terms of appearance, our aerospace vehicle is no different from the space shuttle of the M people, very much like a large delta-wing aircraft. The total length of the design is 47.56m, the height of the landing gear is 20.37m when the landing gear is lowered, and the maximum wingspan of the triangular swept wing is 29.97m, which is mainly composed of three fuselages of the forward, middle and tail sections. ”

"The front fuselage structure can be divided into two parts: the head cone is at the front end of the aircraft, with a good aerodynamic shape and heat protection system, and the core part of the front section is the crew compartment under normal air pressure. ”

This crew cabin can be divided into three levels: the upper deck is the bridge with 3 seats, the middle deck is the living cabin, and the lower deck is the instrument and equipment cabin. The crew cabin can provide astronauts with spacious space to meet the work and life of astronauts who can wear ordinary ground clothing in the cabin. Under normal circumstances, the cabin can accommodate 3~9 people, and in case of emergency, it can also accommodate 12 people. ”

"As for the middle section of the vehicle, it is mainly the payload compartment. This is a large cargo compartment with a length of 23 meters, a maximum diameter of 4.5 meters, and a volume of nearly 800 cubic meters, which can carry a payload of more than 321 tons at a time! The cabin can be loaded with various satellites, space laboratories, large astronomical telescopes, and various deep-space probes, and can fully meet all kinds of space exploration tasks. ”

"In order to cast the payload carried on the track or recover the payload running on the track, the cabin is equipped with one ~ two automatically operated remote-controlled manipulators and television devices. The manipulator is a very thin long rod, which can hardly bear its own weight on the ground, but in the space under weightless conditions, it can quickly and flexibly load and unload more than 20t payloads at one time. ”

"Of course, in addition to providing the cargo compartment structure, the middle fuselage is also the bearing structure of the front and rear fuselages. ”

"As for the rear section of the shuttle, it is more complicated, mainly equipped with three main pulsed energy engines, and the tail section is also equipped with two orbital maneuvering engines and a reaction control system. ”

"After the main engine is turned off, the orbital maneuvering engine can provide the vehicle with the thrust it needs to enter orbit, perform orbital maneuvers and docking maneuvers, and deorbit when returning. The reaction control system is used to maintain the flight stability and attitude change of the space shuttle. ”

"In addition to the powerplant system, there are also pneumatic control components such as lifting ailerons, flaps, vertical tail, rudder and speed brake. ”

As for the specific design and related structural layout, how to adjust and modify the specific design and related structural layout is the next work of Professor Yang and others. I'm just throwing bricks and bricks. ”

"Nevertheless, after everyone's discussion, we agreed that the space vehicle must also reach a minimum maximum take-off weight of 400 tons, the payload can exceed 340 tons, and the maximum speed in space can reach Mach 95, while the adjacent Earth space is Mach 30, as for the range, the one-time injection of fuel can theoretically make the vehicle fly smoothly for 4.5 light years, from the Earth to Proxima Centauri!"

"Of course, this is the perfect form of spacecraft design, and our prototype is likely to abandon some unnecessary configurations at the beginning, except for the core module of the astronauts, other functional areas can be saved, and then retrofitted according to the needs of the later stage. ”

Ferocious, so cruel!

I saw that after hearing Liu Feng's introduction, for a moment, Minister Jiang, who really didn't find an adjective to describe it, could only find the "derogatory word" of ferociousness to describe the shock in his heart.

This is far more than the space shuttle he imagined, and far more than the strategic bomber he expected!

In a way, this is the most murderous flying machine ever designed in human history!

Except for the An-225, which can surpass this thing with a maximum take-off weight of more than 600 tons, all other aircraft on the earth, in terms of load capacity, speed, range and other aspects, will be beaten by this kind of aircraft!

Of course, this should not be the limit of this kind of aircraft, if you can sacrifice part of the range and speed, theoretically, it is no problem to surpass the An-225 in terms of load capacity, and even on the basis of ensuring a certain speed, it can be comparable to the world's largest high-thrust rocket in terms of maximum take-off weight, which is not a problem at all!

Well, the air JUN really doesn't need such a ferocious air-space vehicle, they only need a strategic bomber in the earth's atmosphere that can reach one-tenth of the parameters of such a vehicle, and it is already satisfied......

But can this thing really live up to such murderous design parameters?

In an instant, Minister Jiang felt a little troubled in his heart, this guy, shouldn't he be bragging?

In fact, he was not the only one who came up with such an idea.

Obviously, a group of experts standing beside him also thought of him.

Mach 95, a range of 4.5 light years, and that's still 400 tons!

Oh, I read that right?

The experts present subconsciously rubbed their eyes, but no matter what, there was no change in the data displayed on the PPT!

Professor Zhao Pingyuan, an expert from the Air JUN Equipment Department, had a smile on his face.

Although everyone will more or less draw a pie on it when they are setting up a project, you will draw a pie on it......

It's almost overpowering the earth, right?

Silence, silence.

However, as the eerie silence ended, the sound of discussion spread like a tidal wave.

"It's unbelievable......"

"It's not unbelievable, it's simply impossible! His aircraft can fly directly from the earth into space without relying on a heavy rocket, which is a thing weighing hundreds of tons! Even the Falcon heavy carrier rocket in the world, which is currently the most advanced in the world, can only provide 2,300 tons of thrust, and the payload is only about 60 tons, but he is a good thing, and the payload has reached 340 tons! How is it possible?"

“……”

Hearing the voices of these people's discussions, Yang Xijia, who was beside Liu Feng, took the initiative to stand up, coughed, and said in a teasing tone:

"If there are any questions that can be raised and discussed together, if they can be answered, we will not hide them. ”

To be honest, Liu Feng assigned tasks to them before, and when he first came into contact with these parameters, he Yang Xijia was not much better than these people, but now, don't you also believe in the young man in front of you convincingly?

Although such an occasion is not the time to answer questions, if you can't convince people, they shouldn't be willing to borrow pilots next, right?

Anyway, melon seeds, peanuts, and Xiao Mazha are all ready, so let's assist, and wait for Professor Liu to pretend to be slapped in the face.

Soon, someone was lured by him.

"I have a problem. ”

Professor Zhao Pingyuan raised his hand.

Seeing this, Liu Feng could only nod his head: "Please speak." ”

Holding his glasses, the old man stared at the PPT on the wall for a while, then looked at Liu Feng, and said cautiously:

"Professor Liu, the maximum take-off weight of your aircraft is 400 tons, but the payload has reached 340 tons? In other words, the empty weight of the entire aircraft will not exceed 60 tons?"

Liu Feng nodded: "That's right, to be precise, the weight of the aircraft will not exceed 40 tons." ”

The old man shook his head, and accidentally showed a disappointed expression: "Doesn't that mean that you only used 40 tons of dead weight, and actually held up a load of 400 tons, this kind of efficiency, I can barely believe it on a fighter jet, but on a space shuttle, it's a bit too fantastical, right? I want to ask Professor Liu, are you sure you didn't write a few more zeros?"

If his cognition is not wrong, the efficiency (payload/total take-off mass) of the current active rockets is mostly 0-3%, so if you take 2%, you need at least 50kg of rocket launch for every 1kg load, and Liu Feng is good, and it has been increased to 1000% all of a sudden?

Young man, he really had to suspect that this guy was bragging.

Liu Feng smiled and said, "I can tell you responsibly that everything I said just now can be proved through experiments. After all, our aircraft uses pulsed energy engines, which is different from traditional launch vehicles, its efficiency, in fact, can only hold up 10 times the load, you can increase it several times, but this will sacrifice a lot of speed and range of the aircraft. ”

Professor Zhao shook his head: "Maybe you're right, but this is really beyond my cognition, so I won't delve into the load, but this voyage is ...... How can a 4.5-light-year-40-ton vehicle carry so much fuel? Even if you want to convert this fuel into an atomic bomb, it will be difficult to send a 40-ton spacecraft to a distance of 4.5 light-years, even if the energy of all the atomic bombs in the world is converted!"

However, a small atomic bomb with a charge of 1 kilogram of uranium-235 can theoretically only propel a 40-ton vehicle to fly 225,000 kilometers, while a light year is 9,460.5 billion kilometers, which requires almost 42,000 tons of uranium, which is still theoretically only overcoming the earth's gravity......

Obviously, the old expert obviously didn't know that their pulsed energy engine was the antimatter pulsed energy engine......

Liu Feng looked at the old man, not knowing how to explain, however, he found that the old man was also looking at him, his expression seemed to be a little distressed?

"I understand Professor Liu's eagerness to achieve results, and I also admit that pulsed energy engines are a promising research direction, but ......"

Many people have already whispered to themselves.

However, people who knew the inside story, such as Minister Jiang, had a little embarrassment on their faces.

Liu Feng was also a little embarrassed, thinking to himself that you have never seen the design parameters of the antimatter high-energy particle engine, if you see this thing...... He couldn't even imagine such a scene.

After all, only one high-energy particle engine can easily achieve a carrying weight of tens of thousands of tons, and under full operation, a spacecraft of this weight can reach a maximum flight speed of 0.7 times the speed of light, and the maximum range can reach tens of hundreds of light years!

In comparison, pulsed energy engines can only support a vehicle weighing a few hundred tons to run at a maximum speed of Mach 95 (almost 0.1 times the speed of light), and the range is only a few light years.

It's just a small thing, it's not worth mentioning!

Finally, he still found the words to break the awkward atmosphere:

"To be honest, this is really unbelievable, but facts speak louder than words, and the development progress of our pulsed energy engine can be said to be quite gratifying, and by the end of this year at the latest, you will be able to hear the news of the successful test of such an engine, as for whether it can be done, please wait and see. ”

At this time, Minister Jiang also took the initiative to stand up and relieve the siege and said: "That's right, that ...... Facts speak louder than words, no matter how many doubts there are, will the truth soon be revealed when Professor Liu develops the pulsed energy engine? Ahem, Professor Liu, I wonder if it will be convenient for us to watch this epoch-making engine test run at that time?"

Not only Minister Jiang, but also several others had eager expressions on their faces.

Only the old man just now and several other experts who didn't know were a little unconvinced, this thing is fooling people at first glance, can you believe it?

As for Yang Xijia, who was waiting to watch the excitement, he could only shake his head in disappointment.

No matter how they reacted, Liu Feng only smiled and said: "What's convenient or inconvenient, our kind of engine is originally the main one to use, anyway, we will announce the test news of this kind of engine at that time, and it is also our honor to let our own people see it one step in advance." Of course, if you're really interested, you'll still need to report to the top management one step in advance, and it's not up to me to decide who will be able to enter the test at the time of the test. ”

Seeing this, Minister Jiang also nodded, glanced at the time displayed in the lower right corner of the projection, and said embarrassedly: "That's good." It's not too early, we should go back, Professor Liu, I'm really sorry to delay your precious time. ”

"Well, as for the pilot's business...... No problem at all! I can directly decide, as much as you want!"

The old man patted his chest and reassured.

Hearing the old man's readily agreed, Liu Feng's heart suddenly moved, thinking of the countless astronauts he needed for his big space program next, he couldn't help but swallow his saliva, and said weakly: "How many do you really want? Then, let's have 500 for the time being." ”

5. 500 people?

Old man: "......"
