It is no wonder that Wang Huan was surprised, professional aviation parts transport aircraft are unpopular aircraft in the world, and the demand is very small, and they are not even well known to outsiders.

However, in the specific field of aviation and aerospace manufacturing, the value of such special transport aircraft is immeasurable, and even plays a pivotal role in some aspects.

Because of this, the demand for this type of aircraft is indispensable in some areas.

For example, the National Aeronautics and Space Administration (NASA), because the launch vehicle production plant is located on the west coast, and the launch site is built on the east coast, ordinary small-sized parts can also be transported by land such as trucks or trains, but there is no way to rely on cargo ships to travel south from the west coast through the Panama Canal to the launch site on the east coast.

Not to mention the time and effort, the bumps of the waves also make the components of the space launch vehicle extremely vulnerable to damage, which is very uneconomical.

So NASA used the Boeing-377 aircraft to modify a "Super Guppy" special transport aircraft to transport large-scale space rocket structural components.

Once launched, it achieved very good results, not only shortening the development preparation period of the rocket, but also reducing the damage rate of components to a very low level.

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

At the same time, Airbus has also ordered the "Super Guppy" special transport aircraft to transport large components of Airbus passenger aircraft across 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 production capacity, no strong strength, and it is impossible to play high-end business such as air transportation.

Not to mention anything else, the one-year maintenance of the aircraft is not a decimal, and the fuel for take-off is even more staggering, others are not clear in this regard, Wang Huan, who specializes in aircraft maintenance, knows better than anyone else.

So he was very surprised how Tengfei Group could have this kind of high-end equipment, not that Tengfei Group just produces some drones and small aircraft, and the business in recent years has been miscellaneous.

Just such a person in charge of a company who drills money in the eye actually got a professional aviation parts transport plane, and the Tengfei Group has such a large business volume? Or do you lose money and make money and want to earn some face?

Wang Huan doesn't know whether the business volume of Tengfei Group is large, but judging from the trend of Tengfei Group's gradual contract leader in recent years, the aviation business should not be good, otherwise why engage in infrastructure support?

As for losing money and shouting to earn some face, there may be this possibility, but I have never heard of this kind of thing from public information, you must know that no matter what, this kind of aircraft can be written about, and it is still easy to earn some face.

Qiao Shiming doesn't know Wang Huan's psychological feelings, even if he knows, he probably won't care, in his opinion, the special components in the group, the professional transport aircraft, are all details, and the completion of the Boeing 767 maintenance task is the focus.

After all, this is the first big order received since the establishment of Tengfei Aviation Maintenance Factory, and it must be done well no matter what, so Wang Huan's question is just a simple "um~~".

Wang Huan was still waiting for the answer, but when he heard Qiao Shiming~~, he stretched out his hand and motioned for everyone to walk towards the workshop, and then ...... And then there was no then, almost didn't go crazy on the spot, is this question a little too simple to answer, but I am a guest who came to inspect your business, and finally became interested in your things, shouldn't I do what I like, desperately bragging?

Why is it ~~ gone?

Wang Huan was a little depressed, and said in his heart What kind of people are Tengfei Group, how can a stuffy gourd become the leader of a big factory?

Although he complained in his heart, he still couldn't hold back his curiosity about this type of aircraft, and he was worried about whether Zheng Yongning, the deputy director of the repair plant who was following him and helping them introduce the situation of the factory to Shanghai Airlines, suddenly changed his words and said:

"The JT9D turbofan engine that helped our factory transport is a new model that the group completed the modification the year before last......"

Zheng Yongning is the former Zhuang Jianye's assistant Xiao Zheng, three years ago was put to the front line of experience, successively served as the chief of the logistics department of the aviation power company, the director of the office of the Xiping aircraft manufacturing company, etc., the preparation for the construction of the Tengfei Aviation Repair Plant, Zhuang Jianye personally ordered the general, Zheng Yongning was transferred from the Tengfei Power, arranged to the Tengfei Aviation Repair Factory, promoted to the deputy director of the factory, and assisted Qiao Shiming in handling the administrative work in the factory.

No way, Qiao Shiming is a good hand in technology, but in management and operation is average, although Zheng Yongning is young, he has been by Zhuang Jianye's side for several years, and his management and administration are very strong, which is complementary to Qiao Shiming's team.

It is precisely because of Zheng Yongning's presence that the Shanghai Airlines delegation will not feel like a lovely person who came to inspect the situation, otherwise Qiao Shiming alone, in addition to silence, the rest may be embarrassing.

Of course, Wang Huan didn't know Zheng Yongning's resume, and even if he did, he wouldn't be interested, because Wang Huan at this moment was completely shocked by Zheng Yongning's words.

It turns out that the most important project of Tengfei Group in recent years is not an advanced light transport aircraft, let alone a contractor, but is committed to modifying an aircraft - a special transport aircraft with large-size launch vehicle components.

Military code: Yun 16.

But the space sector prefers to be a "car in the air".

The aircraft is based on the retired Il-18 of the Air Force, and the entire airframe is modified using wind tunnel tests and structural calculations, while the avionics system is more modern.

A large number of advanced composite materials and titanium alloy structural parts are used in the fuselage structure, so as to reduce the weight of the structure as much as possible while ensuring the stability of the overall structure.

The power plant adopts the latest WD-50B turboprop engine of Tengfei Power, with a maximum power of 3400 kilowatts and an axle horsepower of 4622 horsepower.

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

At the same time, the airtight cabin structure and the unique pressurization technology of Tengfei Group are used inside, and the efficient output power and fuel economy of the WD-50B turboprop engine are used to make the flight altitude of the Y-16 "air car" reach 10,000 meters.

This altitude has a stable airflow and reduced drag, which is conducive to the stability of precision components and the improvement of transportation efficiency, coupled with a maximum range of more than 4,600 kilometers, which is enough to cover the launch vehicle assembly plant and the space launch site under the space department.
