Just as the guests lamented that this large passenger plane was powerful and accelerated quickly, its nose was lifted, and it left the ground in just a few seconds and began to climb towards the sky. Although the process was very fast, it did not seem abrupt at all. The whole process was very smooth.

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

The guests soon discovered that this large passenger plane did not have the huge roar of the jet engine when it took off and flew. Its sound was much smaller, and it seemed that it only had jet sounds.

In fact, this large passenger aircraft has a similar engine principle to other aircraft engines. It still relies on oxygen in the air as oxidizer, but uses liquid hydrogen as fuel.

Currently, most of the traditional methods of using liquid hydrogen as engine fuel are used on rocket thrusters. They are temporarily injected into the fuel compartment before the countdown to the rocket launch. Its leakage is simply impossible to control the problem. Its leakage begins at the moment of injecting the fuel compartment until the fuel compartment is burned.

However, Feitian Technology Group's application technology for liquid hydrogen is quite mature, and it can freely control its input. Blueprint automobiles that use liquid hydrogen as fuel are because this is the only way to control the input of liquid hydrogen to replace traditional petrochemical fuel.

Nowadays, 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 complex than automotive engines.

In fact, compared to cars using liquid hydrogen as fuel, aircraft using liquid hydrogen as fuel has more advantages. This is because the mass of liquid hydrogen is small and large. The size of the car limits that it cannot carry too large liquid hydrogen tanks. However, the size of the aircraft is huge. It can even hang liquid hydrogen tanks under both wings or add liquid hydrogen tanks inside the wings. In short, it can increase the space of the liquid hydrogen tank. On the contrary, its mass is small. The weight difference between the same volume of liquid hydrogen and aviation kerosene is more than ten times, so even if it carries more than a little liquid hydrogen, the aircraft can take off easily.

A leader looked at the large passenger plane and said with a smile: "This plane looks quite 'strong'!"

Yes, this large passenger plane looks very 'strong', because the designer used a lot of space on the plane as a fuel compartment when designing it, and it was all equipped with liquid hydrogen.

Tang Xiaochuan told the leader: "Don't you think it looks reassuring? Even if it loses power and is undergoing emergency landings, I believe its fuselage can withstand impacts and high-intensity friction! And if this passenger aircraft is filled with fuel, its range is the farthest among all passenger aircraft, reaching 23,000 kilometers!"

The leader next to him was shocked: "What? There is such a long voyage? Isn't this saying that it has created a world's best?"

"Haha, that's OK. This is just a concept aircraft. In fact, it does not require such a large range when used for passenger operation. However, one thing is certain that it will never be forced to return or find emergency landings due to insufficient fuel. Even if the fuel compartment is leaked, its large fuel reserves can support longer and gain more survival time for pilots and passengers on board!"

"One more point is that the fuel compartment of our large passenger aircraft uses a multi-tank segmented fuel compartment. All tanks are connected in parallel. As long as there is a fuel leakage in one tank, the pilot can immediately close the fuel supply of the tank. The fuel leakage will only leak this tank, and the fuel from other tanks will not leak!"

Some leaders around and representatives of airlines from various countries were very interested in this plane after listening to Tang Xiaochuan's introduction. The 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 an ordinary passenger aircraft. Its maximum flight speed reaches 1620km/h, so at the same flight distance, it arrives one third earlier than the average large passenger aircraft!"

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

Tang Xiaochuan began to transform into a commentator, "This aircraft has a maximum take-off weight of 650 tons, which is larger than the large military transport aircraft with the largest load capacity. Its maximum passenger capacity is 900 people, and its general passenger capacity is 600 people. It has a two-layer structure with top-level - business - economy and three modes of configuration!"

"Its maximum flight distance is 23,000 kilometers, altitude is 13,200 meters, a thrust of 1,700 kN, and an idling distance of 1,600 meters. It can be said that this is a super air giant! If an airline has two or three such passenger aircraft, it can definitely solve the problem of excessive passenger flow during holidays, because the capacity of one of its aircraft is equivalent to several. If it flies in domestic flights, it can even continue to take off without even filling up fuel!"

This passenger aircraft is indeed much stronger in terms of range, maximum take-off weight, maximum passenger capacity, and cruising speed than the passenger aircraft of airlines around the world. Even the latest giant aircraft, known as the French, is not enough to see in front of it. Its name is zg021.

zg021 has attracted special attention from leaders from all walks of life, representatives of airlines and media reporters. This aircraft is so dazzling that its size alone is unforgettable.

Its agile and heroic posture in the air made the guests in the stands amazed. Although it is large in size, it turns and returns quickly and is quick to take off the air, and can easily make some avoidance actions. Just from the ground, its stability in flying in the air is very good, which makes it more reassuring.

When landing, it looks very relaxed and freehand, landing and landing, sliding, the whole process moves smoothly, without any sense of pause when landing.

"Baopaopaopaopao·····" There were bursts of applause in the stands. The guests were very optimistic about this large passenger plane. Representatives of several airlines even planned to suggest that their company place an order with a new energy aircraft manufacturing company, but were worried about the problem of liquid hydrogen fuel!

The next performance was a private passenger plane. The private passenger plane was designed and manufactured for the rich. Its size is much smaller than ordinary passenger planes, and it can only take up more than twenty people at most, and this one carries twenty-two passenger capacity.

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

"In order to increase the safety of passengers, our small luxury passenger aircraft is equipped with automatic early warning radar, which can detect missiles 120 kilometers away in time, which can buy a few minutes of escape time for pilots and passengers on the plane. The aircraft is also equipped with bait. Once the missile reaches a certain distance, the pilot can immediately release the bait and avoid it at the maximum flight speed in time. In addition, 22 people have been prepared on the plane. As long as the landing equipment is on the back, it can safely land and escape! Because these landing equipment will automatically turn on when the falling speed reaches a certain level, even if you forget to open the parachute, there is no need to worry about falling to death. The intelligent system will automatically help you open it, and you can't die if you want to! So you don't have to worry about calculating that the passenger has not undergone parachute training!"

"In the cockpit, the pilot has automatic ejection seats, and all other passengers in the aircraft are parachuted. The pilot can eject out immediately to save his life!"

"The aircraft has a range of 12,000 kilometers. Due to its small size, it can take off and land at some airports with very small altitudes, which will undoubtedly make customers much more convenient!"

This small luxury special plane has aroused the interest of many wealthy people. They came to attend this flight performance and observation meeting to see this small luxury special plane. It is small in size and does not even choose the size of the venue. The long range can basically meet the needs. The facilities equipped on the plane can be called luxury. Although this is just an airplane, there are basically everything on it. What's more important is that early warning radar is installed on it, which can buy passengers a few minutes of escape time. With this time, passengers can land on their backs with skydiving and escape.

Some old rich people who really can't jump to the umbrella can get rid of missile attacks by releasing bait and accelerating memory. For these rich people, it seems not difficult to hire a retired fighter pilot.

This small luxury special plane flies very skillfully and fast in the air, so many wealthy people fall in love with it at a glance.

Next, another small luxury special plane entered the runway. This aircraft also attracted the attention of the rich. Its crew capacity is 18 people, there are various entertainment facilities on the plane, satellite phones, wireless Internet, a range of 13,000 kilometers, and the air pressure in the cabin is very comfortable.

It is also equipped with safety warning radar, a full set of parachuting equipment, and missile bait. In terms of preventing missile attacks, only new energy companies are ahead of the civil aviation aircraft, which is also the reason why these wealthy people are interested in these two private aircraft.

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

Tang Xiaochuan smiled and said, "Sir, all the aircraft produced by our aircraft manufacturing company must use liquid hydrogen as energy!"

The rich man asked, "If I buy a plane, wouldn't I be bothered by the fact that I get liquid hydrogen?"

"Sir, you don't have to worry. The new energy companies under our group have set up branches in countries around the world. They are currently stepping up cooperation with various countries to build liquid hydrogen preparation factories. We are also sending people to cooperate with airlines in various countries to build hydrogen refueling stations on airports, highways and ordinary roads. The fuel used in liquid hydrogen vehicles and liquid hydrogen used in aircraft are the same model, and they are universal!"

"For personal purposes, you can buy liquid hydrogen storage tanks and small hydrogen refueling equipment from our new energy companies' branches around the world. With these, you can inject fuel into your plane at any time!"
