Chapter 609

It's no wonder that Wang Huan will be surprised that professional aviation parts transport aircraft are not popular in the world, and the demand is very small, even unknown to outsiders.

However, in the specific field of aerospace manufacturing, the value of this kind of special transport aircraft is immeasurable, and even plays an important role in some aspects.

Because of this, the demand for this kind of aircraft is essential in some fields.

Take NASA for example. Because the carrier rocket production plant is located on the west coast, and the launch site is built on the east coast, ordinary small-size parts can also be transported by truck or train, but there is no way for large-size parts. They can only rely on freighters to go south from the west coast, cross the Panama Canal, and make a big circle to the launch site on the east coast .

It's time-consuming and laborious. The turbulence of the sea also makes the parts of the space launch vehicle vulnerable to damage, which is very uneconomic.

So NASA modified a "Super Guppy" special transport plane with boeing-377 to transport large-scale space rocket structural components.

Once launched, it has achieved very good results. It not only shortens the development preparation period of the rocket, but also reduces the collision damage rate of the components to a very low level.

Boeing was the first to discover the potential of this special transport aircraft and purchased several for its own Boeing series production.

At the same time, Airbus has also ordered the "Super Guppy" special transport aircraft to transport large parts of Airbus aircraft in Europe, so as to optimize the industrial chain and improve production efficiency.

Because of this, this kind of professional aviation parts transport aircraft is also regarded as a symbol of strength to a certain extent, because there is no considerable capacity, no strong strength, simply can not play the high-end business of air transport.

Among other things, one year's maintenance of aircraft is not a small number, and the fuel taken off is astonishingly high. Others don't know about this. Wang Huan, who specializes in aircraft maintenance, knows better than anyone else.

So he was very surprised that Tengfei group had such high-end equipment. It didn't mean that Tengfei group only produced some UAVs and small airplanes. In recent years, its business has been miscellaneous. Listening to the old man at home saying that Zhuang Jianye had some achievements, he was gone. He was completely in the eye of money. He was short-sighted. He was going to die in such a blind struggle sooner or later.

Just such a person in charge of the enterprise who has made the most of the money actually has a professional aviation component transport plane. Does Tengfei group have such a large business volume? Or do you want to earn some face?

Wang Huan doesn't know that the business volume of Tengfei group is very large. However, judging from the trend that Tengfei group has gradually become a labor contractor in recent years, the aviation business should not be very good. Otherwise, why do we engage in infrastructure support?

As for losing money to earn a bit of face, maybe it's possible, but I haven't heard of this kind of thing from the public information. You know, no matter what, this kind of aircraft can make a lot of books, and it's very easy to earn a bit of face.

Qiao Shiming doesn't know Wang Huan's psychological feelings. Even if he knows it, he won't care. In his opinion, the special components of the group, the professional transport aircraft, are trivial. The key is to complete the maintenance task of the Boeing 767.

After all, this is the first big order that Tengfei aviation maintenance factory has received since its establishment. It has to be done well anyway, so Wang Huan's question is just a simple "um ~ ~".

Wang Huan is still waiting for the answer. As a result, he listens to Qiao Shiming. He reaches out his hand and signals the people to walk towards the workshop. Then Then there was no next. I almost didn't get mad on the spot. Is the answer to this question a little too simple? I came here to inspect the customers of your enterprise, and I finally became interested in your things. Shouldn't I go all out and brag about it?

Why, um ~ ~ after a while, it's gone?

Wang Huan was a little depressed. He said to himself, who are the people of Tengfei group? How can you become the leader of a big factory? Although

make complaints about this type of machine, he is still unable to hold the curiosity about this type of machine. He is not asking whether he is in the process of asking him, and the deputy factory director of the repair factory, who is helping the Shanghai Airlines to introduce the factory situation, Zheng Yongning suddenly turned the conversation forward, saying:

"to help our factory transport the JT9D turbofan engine, is the new model that the group completed the transformation the year before last. …”

Zheng Yongning was Zhuang Jianye's assistant Xiao Zheng. Three years ago, he was put on the front line for training. He successively served as the head of the Logistics Department of the aviation power company and the director of the office of the Xiping aircraft manufacturing company. Zhuang Jianye personally ordered Zheng Yongning to be transferred from the Tengfei power company to the Tengfei aviation repair factory, where he was promoted to the deputy factory director to assist Qiao Shiming in handling the problem Administrative work in the factory.

I can't help it. Qiao Shiming is a good hand in technology, but he is not so good in management and operation. Although Zheng Yongning is young, he has been training with Zhuang Jianye for several years. He is very strong in management and administration, and he is complementary to Qiao Shiming.

It's Zheng Yongning that makes the Shanghai Airlines feel like they've come to investigate the situation. Otherwise, Qiao Shiming alone would be embarrassed except for silence.

Of course, Wang Huan doesn't know Zheng Yongning's resume, even if he does, he won't be interested, because at this moment, Wang Huan has been completely shocked by Zheng Yongning's words.It turns out that the most important project of Tengfei group in recent years is not the advanced light transport aircraft, let alone the contractor, but is committed to refitting a large-scale carrier rocket parts special transport aircraft.

Military code: Yun 16.

But the aerospace sector prefers to be an "air vehicle.".

The aircraft is refitted from the retired Air Force IL-18. It uses wind tunnel test and structural calculation to modify the airframe as a whole. At the same time, it is equipped with more modern avionics system.

Advanced composite materials and titanium alloy structural parts are widely used in the fuselage structure, so as to reduce the structural weight as much as possible while ensuring the overall structural stability.

The power plant adopts the latest wd-50b turboprop engine of Tengfei power. The maximum power of a single turboprop engine is 3400 kW, and the shaft horsepower reaches 4622 HP.

The strong power makes the modified "special air vehicle" increase its maximum carrying capacity by 7.5 tons to 22 tons when its take-off weight is only 1.2 tons higher than that of IL-18.

At the same time, the airtight cabin structure and the unique supercharging technology of Tengfei group are adopted in the interior of the vehicle, together with the efficient output power and fuel saving of wd-50b turboprop engine, which makes the flight altitude of yun-16 "special air vehicle" reach 10000 meters.

At this height, the air flow is stable and the resistance is reduced, which is conducive to the stability of precision components and the improvement of transportation efficiency. In addition, the maximum range of more than 4600 km is enough to cover the carrier rocket assembly plants and space launch sites of the Aerospace Department.
