v2 Chapter 723： new airliner

After leaving Heiyun Bank, Bao Zixuan did not go home. Instead, they came to the aircraft manufacturing center. The Black Cloud passenger aircraft combined with the Soviet Tu-204 passenger aircraft has been designed, and the first experimental prototype has also been built.

Fortunately, the full set of technologies for the new passenger aircraft was exchanged from the Soviet Union through ground-effect aircraft before, otherwise the richest man Bao Bao would not have been able to develop the passenger aircraft.

Bao Zixuan came to the Heiyun Aircraft Manufacturing Center. He had been here several times before, but this was the first time he had seen the aircraft after it was built. Looking at this behemoth in front of me, the beauty of industrial art is vividly displayed, which makes people feel a kind of blood boiling.

At this time, an Asian mixed race saw Bao Zixuan, and immediately stepped forward and said, "Boss, how is our big guy. We have completed many simulated flights, and now that the test flight conditions are met, I will wait for you to come and decide."

To say that this Asian-American aircraft engineer is quite difficult, it is not an exaggeration to describe his family background. Their family has a pivotal position in the world's aircraft history, and it is well-deserved to say that they are the first family of Chinese aircraft design.

Wang Quanming, 36 years old this year; graduated from the Massachusetts Institute of Technology with a major in aerospace design and manufacturing, and has been working at Boeing since graduation. It was Heiyun Group who spent a lot of money, and Bao's richest man promised that he could leave at any time if he was unhappy with his work, and that he was satisfied with Wang Quanming's idea of ​​designing two planes he liked in the future, so he recruited this young talent in the aircraft design industry.

Because of this, he also had a quarrel with Boeing, and Wang Quanming was almost removed from the family. You must know that their family has a tradition in Boeing, and has even been working for Boeing since his grandfather.

Wang Zhu, courtesy name Yupeng, was born in Kyoto, China, and is an aircraft designer and manufacturing technology expert.

In August 1909, Wang Zhufeng was sent to England to study. In 1910, he first entered the Armstrong Naval University in England, and then entered the Vickers factory as an intern. In June 1916, he became a graduate of the second phase of aeronautical engineering at the Massachusetts Institute of Technology and obtained a master's degree in aeronautical engineering.

Wang Zhu is an aircraft designer and manufacturing technology expert who studied abroad to obtain a master's degree in aerospace engineering in China in the early days. Initiated and prepared to build a Hangzhou Aircraft Factory in cooperation with Huamei. During the War of Resistance Against Japanese Aggression, Huaxia Aviation Research Institute was established, and personally participated in the development of various aircraft components of bamboo and wood composite structures. He is one of the main founders of the modern aviation industry in China.

Wang Quanming is the grandson of Wang Zhu, an absolute aviation family. This kind of talent is wanted by all major aircraft manufacturers in the world, but did not expect to eventually come to the Black Cloud Group. It is also from this time that Boeing has regarded the black cloud as an opponent. Not only because of Heiyun's success in aero-engines, but also because of Wang Quanming's joining.

At that time, U.S. Under Secretary of Defense Ginter said that Qian Lao alone could be worth 5 divisions, although Wang Quanming did not have that great ability; but according to Boeing's chief designer, Heiyun Group can get Wang Quanming, at least 5 years less. detour. This is a very high rating and one of the greatest compliments to an engineer.

Bao Zixuan: "It's very spectacular. The seniors have worked hard these days. Looking forward to the moment when it can fly in the blue sky, I don't think it will disappoint. Let me introduce it well. After all, this is the result of the efforts of all the engineers, especially the seniors."

Wang Quanming knew that Bao Zixuan was a polite word. The basis of this plane came from the Soviet Union, and the aero-engine was a mature product of Heiyun. The team he brought over from the United States is more of a role in integrating resources. The role played in this is not very big. Even if you change to an ordinary aircraft designer, you can complete the job very well.

If he wanted to claim credit, he would at most bring some of Boeing's advanced concepts to Heiyun Group; he would not dare to take credit. However, as a Hong Kong enterprise, it is still something to be proud of to be able to manufacture such an advanced aircraft.

Wang Quanming: "Boss, these are all mature technologies. I'm just integrating resources, but I don't dare to take credit."

Bao Zixuan is polite when you call him senior, but he can't push his nose on his face. If you really call each other a junior, what will other colleagues think? You must know that the engineer team of Heiyun Group has a lot of people who graduated from MIT. Could it be that all the engineers who graduated from MIT call Bao Zixuan his apprentice?

Bao Zixuan: "Tell me whether this aircraft can reach the world's advanced level."

Wang Quanming sorted out the language and said: The technical parameters of the Heiyun-1 passenger aircraft;

Although I know the specific design parameters of this aircraft, after production, I still feel that the Soviet aircraft manufacturing level is really good. It is because of the suppression and blockade by the United States that it has not been extended to the whole world. Perhaps there are also financial and institutional factors. After all, the political environment at the time did not allow the Soviets to vigorously develop civil aviation.

The military pressure was so great that the Soviets did not work on passenger planes, and their main energy was on the research and development of military weapons. You must know that in the eyes of the Soviets, if they do not have powerful weapons and equipment, they cannot suppress the Americans.

At that time, when the Soviets produced the Tu-204 passenger plane, the Americans were very nervous. But it was later found that there were problems in the avionics system, operating system, telex system, and engine thrust, but it was just empty. Only then did I gradually feel relieved that Boeing felt that the threat was not as big as it thought, and it could let customers choose by themselves.

At that time, the Soviet Union was already dying, and there was no ability to significantly upgrade and improve the aircraft. Combining a variety of factors, the Tu-204 airliner did not win the international market, it can only be said that it was fate.

But this time it was Heiyun Group that was developing it, and Bao Zixuan was improving the Tu-204. The avionics system was revolutionized, and two industrial computers were placed inside the aircraft alone. The supporting system is also specially developed, which is definitely ahead of this era.

Bao Zixuan: "Senior, how do you think this plane compares to the Boeing 757?"

In fact, it is not only Bao Zixuan who has thought about this issue, Wang Quanming is also constantly comparing the two planes.

The Boeing 757 is a 200-seat single-aisle twin-engine narrow-body medium-range civil transport aircraft produced by Boeing. As oil prices skyrocketed in the 1970s, fuel consumption accounted for an increase in the direct use cost of air transport. The civil aviation aircraft used at that time had high fuel consumption, so there was an urgent need for a new type of civil aviation aircraft with low fuel consumption. In the mid-1970s, Boeing decided to develop a new 200-seat model to replace the Boeing 727 and some of the Boeing 707. Originally named 7N7 (N: narrow body), Boeing officially launched the 7N7 in March 1979 after receiving 40 start-up orders and 42 intentional orders from British Airways and Eastern Airlines The development plan uses new wings and advanced engines on the basis of Boeing 727 to reduce the cost of use by reducing fuel consumption and body weight. In late 1979, the 7N7 was officially renamed the Boeing 757.

The Boeing 757 has the largest range of any subsonic narrow-body airliner, with a range of more than 7,200 kilometers, enough to travel across the Atlantic. It is very similar to the Tu-204 of the Black Cloud upgraded version. It can be said that the two aircraft are bound to become competitors.

Wang Quanming thought for a while and said, "Each has its own merits, and it can be described in terms of difficulty."

"The technology of our aircraft is very advanced, but some of the layouts were not very reasonable when the Soviets designed it, which would invisibly waste the thrust of the engine. But the aircraft has been tested in the wind tunnel, and no one can change it now."

"Boeing 757 is more reasonable in shape design, but the engine thrust-to-weight ratio is worse, and at the same time, it is not as good as ours in some details."

"If these two planes compete, the sales volume should be about the same as long as the price is similar. However, we have to consider Boeing's customer base, so we can't make a definite conclusion yet."

As a former designer of Boeing, the evaluation is very objective. At this time, Bao Zixuan had already made up his mind to fight a price war. Although it was against his original intention, there was no particularly effective method at present.
