There are very few privately-owned aircraft manufacturing companies in China. To establish such a privately-owned aircraft manufacturing company, you need to apply to the relevant departments. This is very complicated, but it has to be done.

During the approval process, Liu Zhiyuan called Tang Xiaochuan to report that day: "Boss, the boss intends to send someone over to review our qualifications for establishing aircraft manufacturing. During the period, we may have to inspect and visit our parts manufacturing plant!"

Tang Xiaochuan said: "This is a good thing. It shows that the relevant departments still attach great importance to our application to establish an aircraft manufacturing enterprise. Please carefully prepare and call me when the leader is about to arrive!"

"Ok!"

That night, Tang Xiaochuan received a call from Liu Zhiyuan, saying that the inspecting leader would come tomorrow morning.

Early the next morning, Tang Xiaochuan and Feitian Technology Group received a group of leaders from the Feitian Building downstairs.

"Boss, this is the Director Luo who led the team to inspect and review our company's qualifications!"

"Director Luo, this is the boss of our group Tang!"

Tang Xiaochuan stepped forward, "Welcome leaders to come and inspect our group!"

Director Luo shook hands with Tang Xiaochuan and smiled and said, "Boss Tang is polite. After your group has handed in the application materials, we have held several meetings in a row. Now there are not many private enterprises in the aviation manufacturing field in China, mainly because The research and development of aircraft manufacturing is strong, and the capital required to be invested is large. Even if it is invested, it may not be rewarding. In the past, it was not that there were no private entrepreneurs who wanted to get involved in this field. I am even more worried that there will be no return after the investment. In the end, they have no choice but to give up. Others have the guts and courage. This time I hope that we will not come in vain. I also hope that your group can support the domestic aircraft manufacturing private enterprises."

Tang Xiaochuan immediately said: "At present, many of our group's subsidiaries are engaged in the production of aviation components and raw materials, such as screws and nuts on airplanes, welding materials, alloy shell plates, windshields, avionics, etc. Now we We have developed aero engines with liquid hydrogen as the main fuel. Our group can produce these key components independently, and we have the ability to independently manufacture civil aviation airliners, agricultural and forestry aircraft, and private jets!"

Director Luo nodded: "I believe that your group can manufacture other parts of the aircraft independently. I have also heard that your aviation materials and parts have a good reputation in foreign trade. This time I am just for the liquid hydrogen fuel aviation engine. Coming!"

"Then please go to our group headquarters for inspection first, and then go to the engine proving ground!"

Director Luo waved his hand: "I won't go to your group headquarters, let's go directly to the engine test site!"

"That's OK!" Tang Xiaochuan agreed, and immediately asked Liu Zhiyuan to prepare the vehicle.

A group of more than a dozen vehicles came out of the Feitian Building and drove for more than two hours before arriving at the aero engine test site located in the suburbs. After close inspections, the convoy was able to enter it.

After the car passed the inspection, Director Luo said to Tang Xiaochuan: "Boss Tang, your safety work here is very strict. It seems that your safety awareness is very high!"

Tang Xiaochuan explained: "There is no way. Since our company started with the production of lithography machines and manufacturing chips, a little bit of reputation has attracted the prying eyes of many domestic and foreign companies. If these companies want to cooperate with us, think We can also consider asking us to authorize technology, etc., but these people are thinking about getting something for nothing, and hire some international thieves to steal technical information. In the past three years, our company has been patronized by international thieves no less than Twenty times, you say you can't be angry?"

“If all companies and enterprises don’t want to invest funds to develop new technologies or upgrade old technologies, but just want to steal them from other companies, how can this society progress? Those companies that have invested heavily in technology research and development Looking at the technology I just researched, I was stolen before I had time to make a profit. I'm afraid I don't want to engage in technology research and development. It's better to spend some money and ask someone to steal it. If things go on like this, a vicious circle is formed, and the development of science and technology Will stop!"

Director Luo nodded and said: "Boss Tang is reasonable, so we have always hated this kind of behavior and severely cracked it down!"

The convoy stopped by a runway. After getting off the car, Director Luo saw a hangar at the end of the runway. There seemed to be an airplane in the hangar, and some ground crews were busy.

"Huh, you have already made the finished product?"

Tang Xiaochuan said: "Leader, this is a test plane. We have built such a plane so far! We hired three people from the retired pilots to serve as test pilots. These ground crews were also dug from various airlines!"

"Can I go and have a look?"

"Of course, leader please!"

When he approached, Director Luo's eyes widened, "Such a big plane, it's bigger than a normal civil airliner!"

Tang Xiaochuan said: "Yes, it is slightly larger than the average Minghang airliner and has a larger passenger capacity. While carrying passengers, there is still a lot of space left in the luggage compartment to carry cargo!"

Director Luo and his party walked up to the aircraft in the hangar. They found that the aircraft was really beautiful. From a glance, you could see that the quality of the aircraft was excellent, with exquisite paint, solid fuselage and wings, and bright. The transparent machine window glass is quite elegant in workmanship.

One of Director Luo's entourage asked: "It is indeed a big technology manufacturing company. This aircraft is so beautifully made. Can it be tested?"

Professor Liang said: "Of course, we have applied for a test flight permit in the nearby airspace!"

Under Professor Liang's arrangement and command, the ground crew quickly completed the overhaul and maintenance work and began to inject liquid hydrogen fuel into the aircraft.

Tang Xiaochuan introduced to Director Luo and others: "That is the equipment for injecting liquid hydrogen fuel into the aircraft, but don't worry, our equipment is very safe, and there will be no liquid hydrogen leakage and explosion accidents!"

After the fuel was injected, the test pilot boarded the plane in his uniform, and a deputy captain boarded the plane to assist.

Only a few minutes later, the aircraft's engine started. Under the pilot's operation, the aircraft slowly moved out of the hangar and entered the runway.

Director Luo asked: "Why does this plane have four engines? The two outermost small engines on both sides seem to be out of work?"

Tang Xiaochuan said: "These two are secondary engines. Under normal circumstances, they can not be used, but their effect is greater. If the aircraft encounters storm clouds during the flight, you can turn on the secondary engine to let the aircraft rise. Leaving the storm cloud area at an altitude of tens of thousands of meters, it also plays a great role in the stability of the flight! If the main engine fails, even if the two main engines cannot work normally, only two auxiliary engines can be used. Let the aircraft return safely at the next altitude!"

"These two auxiliary engines seem to be superfluous and superfluous, but they can make the aircraft land safely in many dangerous situations. For example, when the aircraft is landing at the airport, the captain can completely turn off the main engine. The engine can make the plane glide and land. If you use it well, the plane will land slowly and smoothly!"

At this time, the captain of the test pilot was already driving the plane to accelerate on the runway, and the turbine blades were spinning at a high speed. Everyone could feel the airflow blowing from far away.

The pilot’s skills are superb and the airplane has great power, but he did not increase the speed of the airplane to the maximum at once, but calculated the distance to the runway. After the airplane ran to two-thirds of the length The auxiliary engine was turned on. After the auxiliary engine was turned on, the nose began to rise, and the aircraft slowly left the ground, very stable.

The auxiliary engine only runs for more than ten seconds before it is turned off. Then it is completely powered by the main engine. In fact, the auxiliary engine is not used. The main engine can also make the aircraft normally lift off, but you can try them by turning on the auxiliary engine. Whether it can operate normally, and doing so can also make the plane more stable when taking off.

Some of the entourage of the inspection group was surprised and said: "This plane is so fast, looking at such a big one, but I didn't expect it to be so flexible when turning and pulling up!"

Someone next to him said: "Liquid hydrogen is used as rocket propellant. Can the fuel used to make airplanes keep airplanes from flying fast?"

Professor Liang took the intercom and asked, "Test pilot number two, how is the plane going?"

"Everything is normal, everything is normal!" The test pilot's calm voice came from the intercom.

Director Luo asked Tang Xiaochuan: "Boss Tang, how does the input cost of this plane, such as fuel, compare with the fuel cost of a traditional civil airliner?"

Tang Xiaochuan said: "It's much cheaper. We have compressed production costs to the greatest possible extent. Liquid hydrogen energy vehicles use this liquid hydrogen, and using it is almost the same as using gasoline!"

"This is a big advantage. In addition, the use of liquid hydrogen has no pollution and is fast. When the three are combined, the advantage is already considerable!" Director Luo said.

An accompanying staff member smiled and said, "According to me, the speed of this aircraft is a bit wasted. Civil aviation airliners do not need such a fast speed. If this speed is used for bombers and large transport aircraft, it would be very suitable. I don’t know. Can this technology be used on fighter planes!"

The other people didn't respond much, just as he was joking, but Director Luo was taken aback when he heard it. He seemed to realize something, but he didn't say anything.

The plane flew in the test flight space for more than an hour before landing, and it landed very smoothly.

"The technology of this aircraft is quite mature!" Director Luo sighed inwardly. I can make money by swiping the video.
