Everyone walked in front of this Yun-8K plane, and looking at this transport plane, everyone seemed interested. Of course, in addition to military personnel, Li Tianfeng and others, there are many other people, such as aircraft factories, design institutes, airports, etc., at least hundreds of people.

Minister Liu looked at the Yun-8K, turned his head sideways and said to Zhang Haiping next to him: "Director Zhang, this plane is very different from our Yun-8 before. ”

Zhang Haiping said: "On the basis of the original Yun-8, certain improvements and upgrades have been made, and the cargo compartment is wider and stronger, and many of our wheeled infantry fighting vehicles can be loaded into it." ”

Minister Liu said happily: "In the past, the Yun-8 could not be loaded with infantry fighting vehicles, which was a huge hard injury, and our military's airlift capacity was also greatly reduced. ”

Zhang Haiping said: "Minister Liu, to carry out these aspects of the transformation and upgrading, the key is to have a very good engine, our turbofan 16 engine, comprehensive performance is excellent, the thrust of a single engine is more than 50,000 pounds, such a strong thrust, not to mention a small Yunba, is a larger model of transport aircraft, our turbofan 16 engine can also be competent." ”

Minister Liu is obviously not a technical cadre, and he knows far less detailed and in-depth than Zhang Haiping, and when he heard about the turbofan 16 engine, he immediately pointed to the two engines on the wing and said: "This is our turbofan 16 engine." ”

Zhang Haiping said: "It is our turbofan 16 engine, our Yun8K two turbofan 16 engines, the maximum total thrust is more than 100,000 pounds!" ”

Minister Liu said with great interest: "Let's go, let's first take a look at the turbofan 16 engine." ”

So, everyone walked up to one of the engines. Because the engine is housed in the engine compartment, only the fan blades are visible.

However, the fan blades are very beautiful, not only titanium alloy wide chord hollow blades, but also have a special coating on the surface of the blades, and the blades appear beautiful black.

And that's not all. There is also a beautiful clockwise rotation pattern on the fan blades of this whole plate, which looks more beautiful and exquisite.

As soon as Minister Liu saw this, he immediately said: "Director Zhang, Mr. Li, this is the air intake of the engine, this is the blade of the engine, it looks very good." ”

Li Tianfeng hurriedly introduced, and focused on the fan part, including these fan blades.

After listening to these presentations. Minister Liu said: "It turns out that this is a titanium alloy wide-chord fan blade, I have heard of it, and I finally saw it today."

Minister Liu seemed to be very interested, looked at the fan blades in front of the turbofan engine, turned to the tail spray position of the engine, and looked inside.

Minister Liu said: "Mr. Li, our turbofan 16 engine is not small. ”

Li Tianfeng said: "The turbofan 16 engine belongs to a medium-sized turbofan engine with a large channel ratio, and the diameter of the fan part is one and a half meters. ”

Minister Liu said: "This is a medium-sized turbofan engine. Wouldn't that big turbofan engine be bigger? After speaking, Minister Liu was secretly speechless.

Li Tianfeng said: "Minister Liu." The large large channel than turbofan engine, with a diameter larger than the turbofan 16 and a thrust of more than 100,000 pounds, is mainly used for large military transport aircraft, large long-range strategic bombers, and ultra-large passenger aircraft. ”

Minister Liu nodded. Then he smiled, shook his head lightly and said: "Mr. Li, even if we have large turbofan engines, we don't have large military transport aircraft, let alone large long-range strategic bombers. Such a big guy, with the strength of our current aviation industry, I am afraid that it is still a very long way to go. ”

Zhang Haiping said: "Minister Liu, maybe not necessarily, maybe in a few years, we will have these big guys." ”

Minister Liu shook his head, sighed softly and said, "Director Zhang, I'm not as optimistic as you, maybe, I won't see these big guys appear until I retire." ”

As a senior general of the army, Minister Liu naturally knows the importance of large military transport aircraft and large long-range strategic bombers, but these things are too far away.

Because of this, after the improvement and upgrading, even if it can only be loaded with an infantry fighting vehicle, many military high-level officials are inexplicably happy.

Seeing that the large hatch behind the Yun-8K is opening, probably for the convenience of everyone to visit, Minister Liu said: "For large military transport aircraft, we may not be able to hope for large long-range strategic bombers, let's go to the cargo hold of the plane to have a look." ”

So, everyone walked to the tail of the plane and walked into the cargo compartment from the open hatch.

Minister Liu said: "This warehouse has put a lot of effort into it, can anyone introduce me to the situation of this eight K." ”

Zhang Haiping said: "Minister Liu, this is the design chief model engineer of Yun-8K. After the introduction, Zhang Haiping said: "Mr. Wen, you introduce Minister Liu." ”

Li Tianfeng also knew this Mr. Wen, Wen Hanlin, a medium height, wearing glasses, wearing a white short-sleeved shirt, and looking more energetic.

Wen Hanlin introduced: "Minister Liu, the improvement and upgrading of the Yun-8K transport aircraft is mainly the upgrade of the engine and cargo compartment, the cargo compartment has been widened by 61 cm on the original basis, and the two titanium alloy supports with a width of 30 cm throughout the entire cargo hold have been added, and our infantry fighting vehicles can enter from the tail hatch and then stop in this position......"

Wen Hanping's introduction is also relatively detailed, because it is in the cargo hold, combined with the real thing, everyone understands it as soon as he talks about it, and Li Tianfeng naturally listens very clearly.

The improved Y-8K transport aircraft can carry one infantry fighting vehicle or two 105mm light howitzers, and its transportation capacity has also been greatly improved, which is also a great boon for the current military.

Everyone took a look at the cargo hold, Minister Liu went to the cockpit again, and Li Tianfeng naturally entered the cockpit to take a look, and the entire cockpit has not changed much.

After looking at it, the military and others were more satisfied, and Minister Liu even asked: "How are the preparations for the test flight of this Yun-8K, can it be test-flighted?" ”

Immediately, a person who looked like a person in charge of the test airfield replied: "Minister Liu, the preparations have been completed, and the test flight is ready at any time." ”

Minister Liu waved his hand happily and said: "Okay, then we will carry out the test flight immediately, and I will personally take a look at the test flight of our Yun-8K." ”

Ten minutes later......

Everyone was arranged in the test flight observation area, in the open air, so that they could see the flight of the plane from a full perspective, and Li Tianfeng's interest also came up, looking at the Yun-8K transport plane in the distance.

In the eyes of home, several crew members were neat and orderly, and after entering the plane, the tail door of the plane slowly closed. In the control tower, radio communication was maintained with the aircraft, and several crew members were reporting on the situation before the flight.

"The engine is working!"

"The number of instruments and meters is normal!"

“……”

After reporting the normal situation, the crew sent a request: "One qiē is normal, please take off!" ”

In the command room of the tower, there are not only the commanders of the test airfield, but also many engineering and technical personnel, including the designers and technicians of the Yun-8K, as well as several turbofan 16 engine designers of Tianfeng Technology Company.

When everyone heard the take-off request, there was an inexplicable excitement in their hearts, and many people looked at each other and saw the excitement in each other's eyes, because everyone knew that the plane was about to take a test flight.

Li Tianfeng and others, in the open-air observation area, everyone was looking at the Yun-8K transport plane in the distance, and everyone saw that the plane moved slowly and began to drive towards the designated runway.

"Look, everyone, the plane is moving!"

"What about the tractor, why didn't you see the tractor, is this the start of the plane itself? Why can't you hear the sound of the engine working. ”

Many people are curious, because it is difficult to hear the sound of the engine working, you know, the old turboprop engine of the previous Yunbasi, as soon as the engine starts, the sound is very loud, and the sound of the engine is working.

And this time, it's really weird, the engine is basically not heard.

Hearing everyone's voice, Li Tianfeng smiled, the turbofan 16 engine adheres to ultra-low noise, ultra-low fuel consumption, and ultra-low emissions. In addition, it is a little far away from the position of YunbaK, and everyone is noisy again, and it is normal to stand in this position and not hear the sound of the engine.

In addition, the plane is just heading towards the runway, and the engine is far from reaching the take-off state, and generally speaking, the take-off state of the engine is the most powerful and the most noisy.

Many people pricked up their ears, basically could not hear the sound of the engine, everyone looked at Li Tianfeng and others, everyone knows that the turbofan 16 engine is developed by Tianfeng Technology Company.

Zhang Haiping stood next to Li Tianfeng, and Zhang Haiping said: "Mr. Li, just at the beginning, I gave everyone a huge surprise, and I am becoming more and more interested in this test flight." ”

Minister Liu next to him also said: "Yes, I almost heard the sound of the engine not working, this is the first time, it is simply unheard of!" ”

Li Tianfeng said modestly: "Minister Liu, at this time, the engine has not reached the take-off state, and the sound is relatively small, plus we are a little far away, there are many people here, the sound is noisy, and the sound of the engine cannot be heard, which is normal." ”

Today's three watches, the second one is sent! (To be continued......)
