Chapter 723

After leaving heiyun bank, Bao Zixuan didn't go home. Instead, he came to the aircraft manufacturing center. The black cloud airliner combined with the Soviet Tu-204 airliner has been designed and the first experimental prototype has been built.

Fortunately, before the ground effect aircraft from the Soviet Union in exchange for a full set of new aircraft technology, otherwise the richest man in the package could not have developed the aircraft.

Bao Zixuan has come to the black cloud aircraft manufacturing center several times before, but it's the first time to see an aircraft. Looking at the behemoth in front of us, the beauty of industrial art is displayed incisively and vividly, which makes people feel like blood boiling.

At this time, an Asian hybrid saw Bao Zixuan and immediately came forward and said, "boss, how about our big guy. We have completed many simulation flights. Now we meet the test flight conditions, waiting for you to come and decide. "

It's not easy to say that this Asian aircraft engineer is quite simple. It's not too much to describe him with family background. Their family plays an important role in the history of world aircraft. It is well deserved to say that they are the first family of Chinese aircraft design.

Wang Quanming, 36 years old; Graduated from MIT in aeronautical design and manufacturing, and has been working at Boeing since graduation. It was the black cloud group that paid a huge price. At the same time, Bao Shoufu was chengruo. The other party could leave at any time when he was unhappy at work, and met Wang Quanming's idea of designing two planes he liked in the future, so as to attract the young talent in the aircraft design industry.

For this reason, he also had a very stiff quarrel with Boeing, and Wang Quanming was almost removed from the family. You know, their family has a tradition in Boeing. They have even worked for Boeing since his grandfather.

Wang Zhu, Yu Peng, born in Kyoto, China, is an aircraft designer and manufacturing technology expert.

In August 1909, Wang Zhufeng was sent to England to study. In 1910, he first studied at Armstrong Naval University and then interned at Vickers factory. In June 1916, he became the second graduate of MIT in Aeronautical Engineering and obtained a master's degree in aeronautical engineering.

Wang Zhu was an aircraft designer and manufacturing technology expert who studied abroad in early China and obtained a master's degree in aeronautical engineering. He participated in the establishment of Mawei Naval Aircraft Engineering Office, the first formal aircraft manufacturer in China. It is proposed to establish Hangzhou aircraft manufacturing plant in cooperation with Huamei. During the Anti Japanese War, Huaxia Aviation Research Institute was established to personally participate in the development of a variety of aircraft components with bamboo wood composite structures. It is one of the main founders of modern aviation industry in China.

Wang Quanming is Wang Zhu's grandson and an absolute aviation family. This kind of talent is wanted by major aircraft manufacturers all over the world. I didn't expect to eventually come to heiyun group. It is from this time that Boeing has regarded black cloud as an opponent. Not only because of heiyun's success in aeroengine, but also because of Wang Quanming's joining.

At that time, U.S. Undersecretary of national defense Kintel said that one old Qian could be worth five divisions, although Wang Quanming didn't have such a big skill; However, according to the chief designer of Boeing, heiyun group can take at least five years less detours if it gets Wang Quanming. This is a very high evaluation and one of the biggest awards for engineers.

Bao Zixuan: "it's very spectacular. I've studied hard these days. Looking forward to the moment when it can fly in the blue sky, I don't think it will disappoint people. After all, this is the result of the efforts of all engineers, especially senior students. "

Wang Quanming knows that baozixuan is polite. The foundation of this aircraft comes from the Soviet Union, and the aeroengine is a mature product of heiyun. The team he brought from the United States plays a more role in integrating resources. It doesn't play a big role in this. Even if you change to an ordinary aircraft designer, you can finish this job well.

If you want to make a contribution, you can at most bring some advanced concepts of Boeing to the black cloud group; He can't take credit for it. However, as a Xiangjiang enterprise, it is still proud to be able to manufacture such an advanced aircraft.

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

Steamed stuffed bun Xuan calls you a senior. It's polite, but you can't push your nose and face. What would other colleagues think if they really called each other a student brother. You know, there are a lot of MIT graduates in the engineering team of black cloud group. Is it strange that all the engineers graduated from MIT call baozixuan a younger brother.

Bao Zixuan: "tell me if this plane can reach the world advanced level."

Wang Quanming sorted out the language and said: technical parameters of heiyun-1 airliner;

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 of the United States that it has not been extended to the whole world. Perhaps there are financial and institutional factors. After all, the political environment at that time did not allow the Soviets to vigorously develop civil aviation.

Because of the great military pressure, the Soviets did not work hard on the airliner and focused on the research and development of military weapons. You know, in the eyes of the Soviets, they can't hold down the Americans without powerful weapons and equipment.

At that time, when the Soviet Union produced the Tu-204 airliner, it once made Americans very nervous. Later, it was found that there were problems in avionics system, operating system, Telex system and engine thrust, but there was only an empty meter. This slowly reassures Boeing that the threat is not as big as expected and allows customers to choose by themselves.

At that time, the Soviet Union was already on the wane and had no ability to significantly improve and improve the aircraft. Due to a variety of factors, Tu-204 airliner did not win the international market. It can only be said that it is time and life.

But this time, heiyun group is developing and baozixuan is improving Tu-204 airliner. The avionics system has been revolutionized. Two industrial computers are placed inside the aircraft alone. The supporting system is also specially developed, which is definitely ahead of this era.

Bao Zixuan: "senior, what do you think of this aircraft compared with Boeing 757?"

In fact, it's not just baozixuan who thought about this problem. Wang Quanming is also constantly comparing the two planes.

Boeing 757 is a 200 seat single channel twin engine narrow body medium range civil aviation transport aircraft produced by Boeing company. Due to the sharp rise in oil prices in the 1970s, fuel consumption accounted for an increase in the direct use cost of air transportation. At that time, the fuel consumption of civil aircraft was high, so there was an urgent need for new civil aircraft with low fuel consumption. In the mid-1970s, Boeing decided to develop a 200 seat new model to replace Boeing 727 and some Boeing 707. It was originally named 7n7 (n: narrow body). After receiving 40 start-up orders and 42 intended orders from British Airways and American Eastern Airlines, Boeing officially launched the 7n7 development plan in March 1979. On the basis of Boeing 727, it adopted new wings and advanced engines to reduce the use cost by reducing fuel consumption and body weight. At the end of 1979, the 7n7 was officially renamed Boeing 757.

The Boeing 757 has the largest range among subsonic narrow body airliners, with a range of more than 7200 kilometers, enough to cross the Atlantic. It is very similar to figure-204 of the upgraded version of black cloud. It can be said that the two aircraft are bound to become competitors.

Wang Quanming thought for a moment and said, "each has its own merits. It's OK to describe it with an indistinguishable height."

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

"The Boeing 757 is more reasonable in shape design, but the engine thrust weight ratio is worse, and it is not as good as we do in some details."

"If these two aircraft fight in the arena, as long as the price is similar, the sales volume should be similar. However, we have to consider Boeing's customer base, so we don't dare to draw a clear conclusion yet. "

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