Chapter 503: Giving Wings to Nanyang (First update, please subscribe)
On the empty road, a BMW motorcycle roared forward at high speed.

The speeding motorcycle soon arrived at Nanyang Aviation Industry Company, a large factory located in the southwest of Chang'an. This company was formerly formed by the Italian Savoia Marchetti Company and the French Southwest Aircraft Company. They Together they laid the foundation for the Nanyang aviation industry.

The motorcycle stopped in front of the company guard. After a brief inspection, the motorcycle drove into the company. He parked the car, took off his goggles and helmet, and tidied his hair in the rearview mirror. Zhao Shaojie left the building and soon Soon he came to the studio.

Dozens of engineers from Italy and France are busy here. As an assistant engineer, Zhao Shaojie spends most of his time studying, as do most other Chinese engineers.

The reason why Nanyang Aviation Industries was able to complete the design and production of the "Super Giant" transport aircraft, C95 passenger aircraft and FX1 jet fighter was entirely due to the technical teams hired from Italy and France. Not only the technical team, but also the company's technical workers Thirty percent of employees are of European origin, which can be seen from the "Little Italy" and "Little Paris" near the company.

"We should go with under-wing engine pods."

As soon as he entered the office, he heard Zhang Tingpeng discussing with Chief Engineer Satista. Zhang Tingpeng is one of the only fifty-six Chinese engineers in the company. He was from the first batch of Allied search teams and started working in 44. Internship at Savoia Marchetti.

Satista looked at the new layout on the drawing and said.

"The Comet aircraft uses a wing-root layout. To be on the safe side, we should adopt a similar layout."

It all started with "Comet."

As the pioneer of jet airliners, the "Comet" airliner has indeed set an example for the world.

After they returned to China, Nanyang Aviation Industries began the development of jet airliners.

"Chief Engineer Sa, noise, compared to locating the engine at the wing root, using the engine pod under the wing will make the noise in the cabin smaller and the passengers will be more comfortable."

The "Comet" passenger aircraft has many innovative designs, such as swept wings, pressure cabins, large square windows, etc., allowing it to cruise at an altitude of 13000 meters at a speed of 740 kilometers per hour, which is faster than the piston aircraft of the time. More than double. Moreover, the "Comet" passenger aircraft also has an elegant appearance and comfortable interior facilities, bringing passengers an unprecedented flying experience.

Boeing's development of jetliners was inspired by the "Comet", and the same was true in Southeast Asia. Unlike Boeing, which only saw the real version of the "Comet" at an air show, Nanyang Aviation Industries started cooperation with de Havilland as early as last year. When the Comet passenger aircraft made its first test flight on July 7 this year, engineers from Nanyang Aviation Industries were on site to observe the test flight.

Subsequently, through exchanges and learning between engineers at De Havilland Company, the German and Chinese engineers in the group soon believed that they had mastered the key technical essentials of the jet airliner, that is, the design of swept wings and engines. Choose, and believe that on these two points, the "Comet" passenger aircraft still has room for optimization.

Wang Lun, who has been an intern at Boeing Company in the United States for three years, has participated in the XB47 project and is naturally familiar with engine pod design.

"Passenger aircraft must consider the comfort of passengers. Although its speed exceeds 740 kilometers, considering the special geographical location of Nanyang, whether it is flying to Europe or North America, the distance is about 12000 kilometers. Taking into account the intermediate transfer Time, the flight time is almost 20 hours, and when passengers need to stay on the plane overnight, reducing noise is an issue we must consider."

In fact, the reason why Nanyang Aviation Industry Corporation is very interested in jet airliners is because the distance between Nanyang and Europe and the United States is too far. Take the C95 large four-engine passenger plane manufactured by the company as an example. Although its maximum range reaches 500 kilometers at any time, it can cruise. The speed is only 342 kilometers, and it takes up to 57 hours to fly from Chang'an to Europe. Although this includes the transfer time at the airport, it is really too long.

Because of this, how to shorten the intercontinental flight time has always been a very important issue for Borneo Airlines.

Therefore, Air Borneo seems to be very concerned about jet airliners. After all, the speed advantage of jet airliners cannot be ignored. This is completely different from the attitude that European and American airlines do not take it particularly seriously, even if they have no experience in operating jet airliners. Moreover, for such a hot technology, it is still unknown whether it is safe, reliable and what the operating cost is.

But Air Borneo needs an aircraft that can reduce flight time to less than 24 hours.

Because of this, even though they have tasted the benefits of piston aircraft, it is different from European and American airlines who think that piston airliners like DC-6 and Constellation are quite sufficient. After Air Borneo learned that the "Comet" jetliner had succeeded in its test flight, it set its sights on it.

Of course, there is another underlying reason - Li Yian's support for jetliners also determines the company's development direction.

“Chief Engineer Sa, I think what Engineers Zhang and Wang said is very reasonable. We don’t necessarily have to stick to the rules and blindly follow the British design. Moreover, from the perspective of engine maintenance, the wing root layout is not conducive to Maintenance, our users are airlines.”

Hans Walker, the company's chief aerodynamics expert, also expressed his support for them in a timely manner. As the chief aerodynamics expert of Junkers, he has presided over a variety of projects including the Junkers-287 jet bomber. The development of jet bombers naturally looked down upon the British wing-root layout.

After Walker mentioned "user", Satista thought for a moment and then said.

"Okay, but in the end it still depends on the results of the wind tunnel test. After all, the layout of the wing-root engine nacelle is beneficial to reducing drag and requires lower thrust from the engine."

"Haha, that's already the old imperial calendar."

Hans Walker, who has been in Nanyang for three years, although his Chinese is still a bit stiff, can still quote a common saying.

"You forgot that when the President visited the UK this time, he ordered the RB.80 engine. This jet engine has a thrust of up to 9250 pounds. I heard the accompanying company representative mention that we also cooperate with them at Rolls-Royce. Develop an engine with greater thrust. After it completes the test run, BMW will also produce a new engine. The biggest advantage of using the engine pod is that we can adjust the structure of the pod at any time to adapt to the new engine. As for resistance..."

It is well known that the performance of the engine determines the performance of the aircraft. With more advanced engines, naturally there will be better aircraft.

As the company's chief aerodynamics expert, Walker thought for a while, walked to the drawings, and looked at the aircraft that had been borrowed from the drawings. Its body and wings were borrowed from the design of the "Comet".

"We can reduce its drag by further improving the design of the airframe and wings!"

As an assistant engineer, Zhao Shaojie just listened to the discussions among the engineers. In their discussion, the basic structure of a new jet airliner was formed. Soon Zhao Shaojie Together with colleagues, we made a wind tunnel model and began to conduct wind tunnel testing. In the following days, the model refined the prototype based on the wind tunnel test results. However, we continued to design the landing gear, control surfaces, and wings. Difficulties were encountered when lifting the engine nacelle. Although the progress was hindered, the project is still progressing in an orderly manner.

In order to promote the progress of the project, Nanyang Aviation Industries has also fully cooperated with de Havilland and introduced sub-project technologies including new landing gear and hydraulic control system. These two technologies are also developed by de Havilland. A new technology specially developed for the "Comet" passenger aircraft.

To a certain extent, Nanyang Aviation Industries’ jetliner project is the only jetliner project in the world. These two jetliner projects have had in-depth cooperation from the very beginning, and Nanyang’s research has been carried out for a long time. To a large extent, the UK has benefited.

It is precisely through such fruitful international cooperation that Nanyang Aviation Industry Company, which was only established a few years ago, has been able to grow rapidly. And in the past few years, it has launched a variety of aircraft including the C95 passenger aircraft.
