While the guests were lamenting the powerful power and fast acceleration of this large airliner, its nose had been raised, and it left the ground and began to climb to the sky in a few seconds. Although this process was fast, it was not at all difficult. It is not obtrusive, and the whole process is very smooth.

This not only shows the stable performance of this large airliner, but also shows that the pilot's driving skills are quite superb.

The guests quickly discovered that this large airliner does not have the huge roar of jet engines when traditional aviation fuel aircraft takes off and flies, its sound is much smaller, it seems to only have the sound of jets.

In fact, this is not the case. The engine operation principle of this large passenger aircraft is similar to that of other aircraft engines. It still relies on oxygen in the air as the oxidant, but uses liquid hydrogen as the fuel.

At present, most of the traditional methods of using liquid hydrogen as engine fuel are used on rocket propellers. It is temporarily injected into the fuel compartment before the rocket launch countdown, and its leakage problem cannot be controlled at all. It starts to leak at the moment it is injected into the fuel compartment. until the fuel tank is burned out.

However, Feitian Technology Group's application technology for liquid hydrogen is quite mature, and it can freely control its input. The blueprint car that uses liquid hydrogen as fuel is because it can only control the input of liquid hydrogen so that it can replace traditional fossil fuels.

Today, Feitian Technology Group applies this technology to aircraft engines, which can also be said to be a technological upgrade, because aircraft engines are much more complicated than automobile engines.

In fact, compared with cars using liquid hydrogen as fuel, airplanes have more advantages in using liquid hydrogen as fuel. This is because liquid hydrogen has a small mass and large volume. The size of a car limits it to carry too large a liquid hydrogen tank, but the aircraft Its size is huge, it can even hang liquid hydrogen tanks under the two wings, and can also add liquid hydrogen tanks inside the two wings. , the weight difference is more than ten times, so even if it carries more liquid hydrogen, the plane can take off easily.

After seeing this large passenger plane, a leader smiled and said: "This plane looks quite 'strong'!"

That's right, this large passenger plane looks very 'strong'. This is because the designer used a lot of space on the plane as a fuel tank during the design, and all of it is filled with liquid hydrogen.

Tang Xiaochuan said to the leader: "Don't you think it looks very reassuring? Even if it loses power and makes an emergency landing, I believe its fuselage can withstand impact and high-intensity friction! And If this passenger plane is fully fueled, its range is the farthest among all passenger planes at present, reaching 23,000 kilometers!"

The leader next to him was shocked: "What? It has such a long range? Doesn't it mean that it has created the world's best?"

"Hehe, it's okay. This is just a concept aircraft. In actual use, it doesn't need such a long range when it is used to carry passengers. But one thing is certain, it will never be shut down due to insufficient fuel. Even if the fuel tank leaks, its large fuel reserves can last for a longer time, buying more survival time for the pilot and passengers on board!"

"Another point is that the fuel tank of our large airliner uses a multi-tank segmented fuel tank, and all the tanks are connected in parallel. As long as a fuel leak is found in one tank, the pilot can immediately close the tank. The fuel supply of the body, the fuel leak will only leak this one tank, and the fuel in other tanks will not leak!"

After listening to Tang Xiaochuan's introduction, some leaders around and representatives of airlines from various countries were very interested in this aircraft. A representative of an Eagle Airlines asked: "Mr. Tang, what is the cruising speed of this passenger plane? "

"Its cruising speed is 1500km/h, which is more than 50% faster than the cruising speed of ordinary passenger planes. Its maximum flight speed reaches 1620km/h, so under the same flight distance, it is faster than ordinary large passenger planes." Arrived in a third of the time!"

At this time, a boss of Xiongguo Airlines asked: "Mr. Tang, how many passengers can this plane carry at one time, and what is the maximum take-off weight? What is the internal structure like?"

Tang Xiaochuan began to become a narrator, "The maximum take-off weight of this aircraft has reached 650 tons, which is larger than the current large-scale military transport aircraft with the largest load. It can carry up to 900 passengers, and the general passenger capacity is 600. It is a two-tier structure, first-class-business-economic three-mode configuration!"

"Its maximum flight distance is 23,000 kilometers, its flight altitude is 13,200 meters, its thrust is 1,700 kN, and its no-load taxiing distance is 1,600 meters. It can be said that this is a super giant in the sky! If an airline has two or three This kind of passenger plane can definitely solve the problem of excessive passenger flow during holidays, because one plane can carry several planes, and if it is a domestic flight, it can continue to take off without refueling!"

This passenger plane is indeed much stronger than the current passenger planes of various airlines around the world in terms of range, maximum take-off weight, maximum passenger capacity, and cruising speed. Even the latest giant aircraft known as the French Super Airbus is in front of it. Not enough to see, its name is ZG021.

ZG021 has attracted special attention from various leaders, airline representatives and media reporters. This aircraft is so dazzling that it is hard to forget just by looking at its size.

Its vigorous and heroic posture in the air amazed the guests in the stands. Regardless of its size, it turned quickly and flexibly, took off quickly, and could easily make some evasive actions. The stability of the flight is very good, and this feeling is more reassuring.

When landing, it looks very relaxed and freehand. The whole process of landing, landing, and gliding is smooth, and there is no sense of frustration when landing.

"Papapa..." bursts of applause erupted from the stands, and the guests were very optimistic about this large passenger aircraft. Representatives of several airlines even planned to suggest that their companies place orders with new energy aircraft manufacturing companies. , but worry about the problem of liquid hydrogen fuel!

The next show is a private airliner, which is designed and manufactured for the rich. Its size is much smaller than that of ordinary airliners, and it can only accommodate more than 20 people. The quantity is twenty-two.

A staff member introduced: "This is a small luxury airliner with a rated passenger capacity of 22 people. In addition to the cockpit and passenger seats, there are lounges, toilets, refrigerators, kitchenettes, luggage compartments, and entertainment rooms on it. , conference room and more!"

"In order to increase the safety of passengers, our small luxury airliner is equipped with automatic early warning radar, which can detect missiles 120 kilometers away in time, and can buy a few minutes for the pilot and passengers to escape. The aircraft is also equipped with Once the missile flies within a certain distance, the pilot can immediately release the bait and evade it in time at the maximum flight speed. In addition, 22 landing equipment are prepared on the plane. As long as the landing equipment is on the back, they can land safely and escape !Because these landing equipment will automatically open when the falling speed reaches a certain level, even if you forget to open the parachute, you don’t have to worry about falling to your death, the intelligent system will automatically help you open it, and you can’t die if you want to! Don't worry about skydiving training!"

"In the cockpit, the pilot has an automatic ejection seat, all other passengers in the plane jump out, and the pilot can eject immediately to save his life!"

"This aircraft has a range of 12,000 kilometers. Due to its small size, it can take off and land at some high-altitude and small airports, which will undoubtedly make it much more convenient for customers!"

This small luxury plane has aroused the interest of many rich people. They came to this flight show to see this small luxury plane. It is small and does not even choose the size of the venue. The equipped facilities can be called luxurious. Although this is just an airplane, it basically has everything on it. More importantly, it has an early warning radar installed on it, which can buy passengers a few minutes of escape time. At this time, passengers can parachute and escape with their landing equipment on their backs.

Some older rich people, if they really can’t jump out of the sky, as long as the pilots are skilled, they can avoid the missile attack by releasing the bait and speeding up. For these rich people, it seems that it is not difficult to hire a retired fighter pilot .

This small luxury special plane flies very dexterously and fast in the air, and many wealthy people have taken a fancy to it at a glance.

Next, another small luxury plane entered the runway. This plane also attracted the attention of the rich. It can carry 18 people. There are various entertainment facilities on the plane. It has reached 13,000 kilometers, and the air pressure comfort in the cabin is very good.

It is also equipped with a safety early warning radar, a full set of parachuting equipment, and missile bait. In terms of preventing missile attacks, only new energy companies are in the forefront of civil aviation aircraft. Reasons for private jet interest.

At this time, a rich man asked: "Mr. Tang, do these two types of private jets burn aviation fuel or liquid hydrogen?"

Tang Xiaochuan said with a smile: "Sir, all the aircraft produced by our aircraft manufacturing company must use liquid hydrogen as energy!"

The rich man asked: "If I buy an airplane, don't I have to worry about getting liquid hydrogen?"

"You don't have to worry, sir. The new energy companies under our group have set up branches in various countries around the world. We are stepping up cooperation with various countries to build liquid hydrogen production plants. We are also sending people to cooperate with airlines in various countries. Cooperate to build hydrogen refueling stations at various airports, highways and ordinary roads, the fuel used by liquid hydrogen vehicles and the liquid hydrogen used by airplanes are the same type, and they can be used in common!"

"Privately, you can purchase liquid hydrogen storage tanks and small hydrogen refueling equipment from our new energy company's branches around the world. With these, you can refuel your aircraft at any time!"
