In addition, anyway, it is the field test flight verification of the engine, which can be installed on the Yun-8 or on the C919, and a series of test flight verifications can be carried out.

Li Tianfeng said: "Director Zhang, your call is really timely, one day later, I will not have a turbofan 16 delivered to the military, and our Yunba will also have no turbofan 16 engine installed for the time being." ”

"Oh." Zhang Haiping said suspiciously: "Mr. Li, what's going on, please?" ”

Li Tianfeng smiled, briefly explained the matter, understood the reason for the matter, and said apologetically: "Mr. Li, I am equivalent to cutting off the beard, and the two turbofan 16 engines that I was originally going to give to COMAC were asked to come over." ”

Li Tianfeng said: "Director Zhang, it doesn't matter, we will immediately speed up the production and manufacture of two turbofan 16 engines, about a month or so, a month later, COMAC's C919 passenger aircraft can also be equipped with our turbofan 16 engines." ”

Zhang Haiping said: "Mr. Li, wait a minute, I will call COMAC immediately and explain the reason to them, I believe they can also understand." ”

Zhang Haiping's meaning was very obvious, he didn't want Li Tianfeng to be difficult, and Zhang Haiping himself came forward to explain the reason, after all, Li Tianfeng had already promised Ma Delong just now.

Li Tianfeng's heart was light, this is the best, so Li Tianfeng said: "Director Zhang, then thank you." ”

The two negotiated the two turbofan 16 engines on the phone, and these two engines will be immediately sent by Tianfeng Technology Company to the Yun-8 aircraft factory, and then installed on the modified Yun-8 aircraft as the power of this modified Yun-8 transport aircraft.

Zhang Haiping did not break his promise, and after talking to Li Tianfeng on the phone, he personally called Ma Delong of COMAC. After explaining the matter, Zhang Haiping, a major general of the General Staff Armament Department, personally called, and Ma Delong naturally had no objections.

It didn't take long for Ma Delong to call over, and Ma Delong said: "Mr. Li, Director Zhang told me about the situation just now. The military is first, we don't have any opinions, our C919 airliner will wait another month, it doesn't matter. ”

Li Tianfeng didn't expect that Ma Delong didn't have any opinions, Li Tianfeng was also happy in his heart, and he was completely relieved in his heart, and there was no pressure at all, Li Tianfeng said: "Mr. Ma." Thank you for your understanding, within a month, we will definitely produce two turbofan 16 engines to ensure the test flight of your C919 airliner. ”

Modifying two turbofan 16 engines, the C919 airliner will naturally have to carry out a series of test flights, the test engine is one aspect, and the C919 airliner itself will also undergo some test flights and verification.

Li Tianfeng and Ma Delong talked on the phone again and negotiated the production and manufacture of two more turbofan 16 engines. Pleasant end of the call.

…………

The military's work efficiency was very high, and it was the morning of the second day after Li Tianfeng and Zhang Haiping finished talking on the phone. Two military trucks, one loaded with a turbofan 16 engine, drove out of the test engineering center and transported the two engines to the Yun-8 transport aircraft manufacturing plant.

Tianfeng Technology Co., Ltd. produced and manufactured two turbofan 16 prototypes, which will be used for the test flight of the C919 passenger aircraft, and said that the two turbofan 16 engines that were shipped out are not listed.

The two turbofan 16 engines were transported to the Yun-8 aircraft factory. After entering the factory area, drive straight into the huge aircraft assembly workshop.

In the aircraft assembly workshop, a basically completed Yun-8 transport plane quietly parked in the huge and spacious assembly plant, and people who are familiar with the Yun-8 aircraft can see at a glance that this Yun-8 aircraft is a little different from the previous Yun-8.

Y-8 transport aircraft. It was originally a four-engine turboprop medium-range transport aircraft, which was mainly used for various purposes such as airdrop, airborne, transportation, life-saving and marine operations. The aircraft is based on the An-12 transport aircraft designed by the Soviet Antonov Design Bureau.

The Y-8 is the main transport aircraft of China's Air Force, and the Y-8 has played an important role in national defense and national economic construction. In addition, a portion of the Y-8 transport aircraft was exported to a number of countries.

That is to say, as a main transport aircraft of the current military, the use of the eight is very wide, China's vast territory, a strong army, also need an excellent transport aircraft, however, the eight old, and Europe, America, Russia and other countries in the main force of the military transport aircraft, the gap is a little big.

As the first medium-sized transport aircraft equipped with a large number of units in the Chinese Air Force, the Y-8 transport aircraft has played an important role in national defense construction and economic development. However, after all, the Y-8 was copied from the Soviet transport aircraft in the 60s of the last century, and its cargo compartment volume was relatively small, and it cooperated with the new army emergency response speed, fast speed, and poor mobility ability.

In addition, an important feature of the army's armament in the new century is that it is equipped with a large number of 8x8 wheeled combat vehicles, such as the Stryker infantry fighting vehicle in the United States. Therefore, the newly developed military transport planes of various countries, such as the An-70, C-X, and A400M, have increased the cargo compartment, especially the height and width, and it is more difficult for the Y-8 to carry these armored vehicles.

China's new VN-1 8x8 armored vehicle has been finalized and has begun mass production to equip the troops, so although the performance of the new model of the Y-8 military transport aircraft has been compared with that of the C-130J, its application prospects are limited. Therefore, the Chinese Air Force needs larger, newer transport aircraft to support the future emergency combat force of the Chinese Army.

A new type of transport aircraft, if it is to be developed, requires a large investment, requires a relatively long cycle, the military also knows that according to the current level of the domestic aviation industry, it is unrealistic to launch a new military transport aircraft project now.

There are only two most effective and fastest solutions, the first is to consider importing and purchasing more advanced foreign transport aircraft.

However, this is basically difficult, and the only country willing to sell us military transport aircraft should be Russia, and it is a relatively backward transport aircraft, and importing this road is not an ideal road.

The second is to consider the upgrading and transformation of the Yun-8, the development of the turbofan 16 engine of Tianfeng Technology Company, which has made many high-level military officials shine, which is why there is this improved Yun-8.

The improved Yun-8, codenamed Yun-8K, was changed from the previous four turboprop engines to the current two turbofan 16 engines.

With the turbofan 16 engine with excellent performance, the Y-8K enlarged cargo compartment, especially the heightened and widened reinforcement, can carry China's new VN-1 8x8 armored vehicle.

The Yun-8 in the assembly plant looks obviously a little different from the previous Yun-8, the engine is changed from four turboprop engines to two turbofan 16 engines, and the fuselage looks very similar to the previous Yun-8, but it is obviously thicker and wider.

Next to this brand-new Y-8K, there are already many people, not only middle and senior managers of aircraft factories, but also many technical personnel, and even a few soldiers wearing military uniforms, and the highest rank is actually a colonel.

"Look, look, the engine is coming!"

Hearing this, everyone looked over, only to see two military green military trucks slowly driving in from outside the gate, and after driving into the factory, they stopped not far in front of everyone.

The aircraft assembly plant is naturally very huge, and it is very convenient for the truck to enter, and the truck is stopped, and someone immediately said happily: "Take a look at the engine, I have long wanted to see an engine." ”

"No hurry, no hurry!" A man who looked like a high-level man at an aircraft factory shouted loudly, then waved: "It's not too late to wait for the engine to come down from the truck." ”

"Quick, quick, get the engine down right now."

The whole scene was busy, everyone's eyes did not leave the two trucks, and there were many people around the trucks, all wanting to see the true face of the turbofan 16.

"Let's get out of the way, step back!"

After everyone retreated, the two engines were lifted from the truck, because they had to be transported long distances, the engines were naturally packed in boxes, and when they were hoisted down, they were hoisted down together with the packing boxes.

The engine was hoisted down and placed on the ground, and everyone immediately couldn't wait to surround it, and someone said loudly: "Quick, open the box!" ”

Without waiting for the workers to come over, a few young technicians opened the boxes of the two engines with all their hands, and this thick green wooden box is also easy to open.

As soon as the box was opened, the two engines were fully displayed in front of everyone!

"Wow! This is the turbofan 16 engine! ”

"It's so beautiful, it's a little more beautiful than what you see in the pictures!"

"Such an engine, you can see that it is good at a glance, you see, how exquisite, especially some details, are very exquisitely made, like a work of art."

“……”

Everyone gathered in front of these two engines, elated, excited, and happy for a while, especially those technicians, who said with a happy face.

The middle and high-level officials present at the aircraft factory were obviously also knowledgeable people, and after looking at these two engines, they were also satisfied.

"Lao Chen, you see, it is worthy of the 4th generation large bypass ratio turbofan engine, which is very good!"

"Yes, Lao Zhu, look at this air intake part, look at this wide fan blade, it is very exquisite, and it is no different from foreign advanced engines!"

"I can't imagine that our Y-8 transport plane can be equipped with such an excellent engine!"

“……”

Several middle and high-level people in the Yunba Aircraft Factory looked happy and very satisfied with the two engines.

The military representatives next to them, after looking at the two turbofan 16 engines, also nodded their heads and even gave them a thumbs up.

………….

Today's two watches, the first one is sent first, the second one is a little later, and the code word is written after dinner.

This morning's military parade was really wonderful and exciting, and after watching it, the pride of a great country in my heart could not be dissipated for a long time. (To be continued......)
