"Chairman, you're finally here, I thought you forgot about us. Pen & Fun & Pavilion www.biquge.info "Montreal Bombardier Aviation City, no, it should be called Ambrera Aviation City now, Zhou Yuanhang saw Ling Shizhe coming, and complained a little resentfully.

After Ling Shizhe received the first aircraft developed by Ambrera Company, the "Little Bee" agricultural and forestry aircraft, and obtained the FFA airworthiness certificate issued by the Federal Aviation Administration, he almost forgot that he had designed the small aircraft, although he only drew a sketch at the beginning, put forward various performance requirements of the aircraft, and the specific design and development of the aircraft were all in charge of the team led by Zhou Yuanhang, but according to the practice of the international aviation industry, he was the chief planner of the "Little Bee" aircraft.

However, Ling Shizhe, the chief planner, doesn't seem to care about this plane at all, except for the first test flight of the "Little Bee", he has never been here, and even where the development progress of the aircraft has reached, he has not asked once, as if he has completely forgotten about this aircraft.

Ling Shizhe's indifference discouraged the employees of China Aircraft Aviation Industry Co., Ltd., as if they had been neglected and became a dispensable role among Ambrera's many subsidiaries.

However, at this time, Zhou Yuanhang stood up and continued to cheer everyone up, so that the morale of the employees did not completely collapse.

Although Zhou Yuanhang was trying his best to maintain the morale of the company's employees, he didn't complain to his boss that it was fake, so the first thing he said when he saw Ling Shizhi was to complain to Boss Ling.

Ling Shizhi patted him on the shoulder and said, "I'm sorry, I'm really a little negligent to you, but you know I'm too busy to take care of this side a lot of the time. You know, I don't know much about airplanes, and if I've been here too many times, I might be tempted to point fingers. You don't want to see a layman in a blind command there, do you? ”

Zhou Yuanhang smiled and said, "You really have confidence in me. ”

"Not confidence in you, but confidence in the company, in all the employees of the aircraft plant." Ling Shizhe argued strongly.

"Let's go, I'll take you to see our new plane." Zhou Yuanhang knew that Ling Shizhe was making excuses, but he was not prepared to dwell on this issue. He knew that although Ling Shizhe had only been here once or twice, he cared very much about this aircraft company in his heart, although Ling Shizhi did not understand airplanes, he had always been silently supporting him in the back.

To give funds, what kind of talents do he want to find, in addition, Ling Shizhe knew that the research and development strength of the aircraft company was very weak, so in order to make them less detours, from his laptop. found a lot of successful aircraft design ideas and design concepts in later generations, all of which were handed over to Zhou Yuanhang.

In order to ensure that the aircraft manufactured by Ambrera can be unique in the market, open avionics system, fly-by-wire system, engine numerical control system, etc., Ling Shizhe has been urging those developers, it seems that he has not done much, but behind the scenes, he has done a lot.

Come to the test flight site. The runway was already crowded with people, and the employees of the aircraft factory were not only those who stayed on duty. Everyone who could come was here, and there were many employees from other subsidiaries who came to celebrate the company's first aircraft to obtain the FFA airworthiness certificate, and they were still very excited, even though it was only a small propeller aircraft.

No way, Canada this country. Life is quiet to the point of tranquility, but it's just too boring, so even the slightest thing can make Canadians happy for a long time, and even have a party for it. A big event like getting an FFA airworthiness certificate from an aircraft can make them even more excited for days.

When he arrived at the edge of the runway, Zhou Yuanhang took the walkie-talkie from his assistant and shouted, "The ceremony begins!" ”

The intercom emits the voice of the tower commander, "Yes, 001, the ceremony begins!" ”

I saw a plane slowly approaching on the runway and began to enter the runway.

Seeing the plane coming, the crowd burst into warm applause, and many people even set up their computer cameras and slammed at the planes in the runway.

I have to say that the aircraft designed by Zhou Yuanhang's team is very beautiful in appearance, and the "Little Bee" aircraft refers to the Polish M-18 "dromedary" aircraft, which is a large agricultural aircraft with a single wing and all-metal structure, equipped with a Polish-made piston star engine with a maximum power of 987 horsepower, which is famous for its high cost performance.

But the M-18 has one of the biggest shortcomings, that is, the appearance is too ugly, if it were not for the ugly appearance, I believe that the sales of the "single hump" aircraft in history would be far more than 5,000 units.

The "Single Hump" aircraft was born in 1964, when Poland was still a socialist country, and although the M-18 had excellent performance, it could only be sold in the countries of the red camp, until the drastic changes in Eastern Europe and the collapse of the Soviet Union, the M-18 began to enter the market of Western countries.

It is still the Cold War period, the M-18 has not yet entered, and there are no aircraft of the same type on the market, Ling Shizhe can just make a time difference and let his "little bee" occupy this market gap.

I remember that in the previous life, Poland's M-18 sold more than 200 units every year, with a unit price of 650,000 US dollars, which seems to be a small profit, but it can be added up, and this profit is also quite a delicious cake for the current China Aircraft Aviation Industry Corporation.

Zhou Yuanhang got the sketch of the M-18 given to him by Ling Shizhi, and after going back, on the basis of retaining its basic performance parameters, he made a thorough facelift on the shape of the M-18 to make it beautiful to conform to the aesthetics of Westerners.

The beams and longitudinal beams of the "Little Bee", that is, the skeleton of the aircraft, are made of the third-generation A+B titanium alloy material developed by the Ambrera Materials Laboratory, and the aircraft skeleton is made of this titanium alloy, which is much lighter in weight than the metal frame used in the M-18.

In order to further reduce the weight of the aircraft, Ling Shizhe adopted the aircraft skin production process of the Airbus A380.

Here's how the Airbus A380 aircraft skin is made.

The principle of A380 skin is actually very simple, the skin uses only two materials, that is, aluminum alloy and glass fiber, and the aluminum alloy is pressed very thin when making, which is one-third thinner than ordinary paper. Then the fiberglass is pulled to one-thirtieth of the thickness of a hair, and then the fiberglass is woven into a "fiberglass cloth", and then a special glue is coated on the aluminum alloy, and then the "fiberglass cloth" is pasted on the aluminum alloy, and after the glue is dry, it is sent to a high-temperature furnace to bake.

At high temperatures, "fiberglass cloth" under the action of glue. The aluminum alloys are tightly bonded together, and finally a special heat treatment is done, and the A380 composite skin is completed.

The composite skin was six percent lighter than traditional composite skins, but it was 15 to 20 percent stronger, harder, and tougher than steel, which at the time was called the world's lightest and strongest airplane skin, which shows how strong the material was.

The principle seems simple, but it is really difficult to do, first of all, you have to figure out what kind of adhesive is used for the composite skin of the A380. What is the temperature of the high-temperature furnace, what kind of heating method is used, how to heat up, what kind of heat treatment is done, even if it is a small link that is not mastered, you don't even think about the skin of A380.

Fortunately, the later republics overcame this technical difficulty, and also published the detailed process flow on the professional material website, which gave Ling Shizhe the opportunity to get the A380 aircraft skin out. Otherwise, it would be a fantasy to give him thirty years.

This kind of skin Ling Shizhe named BL-01, and after it was developed, Ling Shizhe did not apply for a patent. Because the production process of this material is so special, applying for a patent is tantamount to making the production method public, so Ling Shizhe adopted Coca-Cola's method and put BL-01 in the vault of Hong Kong Lvsheng Bank for safekeeping.

BL-01 skin technology is so important to Ling Shizhe that it can be used not only on the current "Little Bee" aircraft, but also on regional airliners, trunk airliners, business jets, and military aircraft. It's about whether he can have a place in the aviation industry.

After all, there is a gap of more than 40 years between the two in aviation material technology, and the Polish "single hump" aircraft is only a propeller aircraft, and the Polish government cannot use supercomputing to optimize the structure of the "single hump". What's more, there is a question mark over whether Poland has a supercomputer or not, at least Poland's supercomputer is definitely not as good as Ling Shizhi's supercalculation.

With this in mind, it is not an exaggeration to say that the body platform of the "Little Bee", which is the same size as the "single hump", is 40% lighter.

The weight is reduced, and there is no need for such a high-horsepower engine, the 600-horsepower 8-cylinder twin-supercharged turbo aero engine is completely sufficient, so that the fuel consumption and weight of the aircraft will be further reduced, and finally the maximum load of the aircraft reaches an astonishing 3280kg, which is 800kg higher than the 2470kg of the "single hump".

With so many high-tech materials, the cost of the "Little Bee" will definitely be much higher, but on the whole, the "Little Bee" is more cost-effective than the M-18.

Today's flying "little bee", white is the main color, in conjunction with the festive Chinese red, plus the beautiful wings painted with gold edges, the original plane looks very beautiful.

Looking at the plane, Ling Shizhe couldn't help but nodded, quite satisfied with the appearance design of the plane.

The plane slowly entered the runway, and the engine working sound was very smooth and very slight.

This engine is the GK-1 aero engine developed by Ambrera Power Company, which is different from the piston star engine used in M-18, it is a water-cooled engine, focusing on high performance, low noise, low fuel consumption, low emissions, high reliability and high maintenance, Zhou Yuanhang, who was standing next to him, told him that this engine is cast with all-titanium aluminum alloy, which is 11% lighter in weight and 20% less fuel consumption than the aero engine of the same power on the market. The engine also received an FFA airworthiness license.

Seeing the plane enter the designated runway, the crowd that had gradually quieted down in the visiting area began to be lively again, and everyone was lively and talked about the plane.

The plane entered the runway, and after waiting on the runway for a few minutes, the plane started moving again and began to taxi on the runway.

At this time, someone in the crowd shouted, "Look! The plane is taxiing, and it looks like it's about to take off! ”

Many people shouted excitedly, their tones were full of excitement, and the engine gradually increased its power from the slow state to the take-off state.

In the take-off state, the sound of the engine is significantly increased, the speed has reached the maximum speed, the engine installed on the nose is pulling more and more, and the aircraft has entered the stage of rapid acceleration.

The engine reached the maximum power state, but the sound was still stable, hearing the sound of the engine working, Ling Shizhe nodded, this should be the least noisy aero engine in the same engine.

"The plane has accelerated and is ready to take off!"

"The plane accelerates beautifully, it's still very stable, and the sound of the engine is so good!"

"Yes! And the sound is not too loud, it is very stable, and it sounds very powerful! ”

Ultra-low noise, at this moment, is vividly reflected, many people are surprised, especially those professionals in the aviation field, seeing this scene, hearing the sound of this engine working, many people look at each other, and nod slightly.

The plane accelerated, faster and faster, and then, in the midst of all the attention, the plane left the runway and flew towards the blue sky, gradually moving away, and the plane became smaller and smaller in everyone's eyes.

Successfully fly into the blue sky!

Perform perfectly!

Seeing this scene, many people in the entire viewing area applauded, and the thunderous applause lasted for a long time. Ling Shizhe and Zhou Yuanhang's faces were full of joy and joy.

"Little Bee" flew into the sky, began to fly over the test flight field, because "Little Bee" is an agricultural aircraft, not used to perform stunts, so its movements are very simple, in the air mainly shows its excellent low-speed and low-altitude performance, far less than the air show used to carry out a special performance of the aircraft so good-looking.

The plane performed in the sky for fifteen minutes, and then adjusted its attitude and prepared to land.

Chirping! A beautiful tricycle landed on the ground at the same time, braked and slowed down, and the speed of the plane began to slow down rapidly, and finally slowly moved on the runway.

When the plane was still 50 meters away from the visiting area, the fire trucks parked in opposite rows on both sides of the runway sprayed a water dragon at a 45-degree angle to the high altitude of the other party.

Zhou Yuanhang told Ling Shizhe, "this kind of ceremony is called" water gate ", whenever a new aircraft joins, or the new aircraft developed to get a flight license, will carry out the "water gate" ceremony, so that the aircraft is baptized, meaning "to catch the wind and wash the dust", in addition, the traditional way of celebration in the civil aviation industry is to knock champagne on the plane, etc., for example, when the Boeing 747-100 was launched, the "champagne" celebration ceremony was also implemented.
