Transport-8K on the plane.

Several crew members, how could it be otherwise, everyone had obviously started the engine, the plane was also moving, and they were slowly driving under their own control, heading towards the designated runway, but everyone felt very strange.

These crew members are very experienced, and they often fly the Y-8 aircraft, otherwise, they will also be arranged to take over the test flight mission of the Y-8 aircraft.

"Xiao Li, the engine has started?"

"Head, it's really started, you listen, isn't there the sound of an engine?"

"It's weird, the sound of this engine is so quiet, much quieter than the previous turboprop engine."

"Head, I heard that the turbofan 16 engine was developed for civil airliners, and full consideration was given to comfort, ultra-low noise, ultra-low vibration is the most basic requirement."

The head of everyone's mouth, that is, the captain of these crew members, a middle-aged pilot, nodded, and then said: "We will enter the scheduled runway soon, everyone is focused." ”

Open-air observation area.

There are really a lot of people here, hundreds of people, not only military personnel, Li Tianfeng and others, but also many aircraft factories, aircraft design people, and people at the airport are even more exaggerated almost all of them have run here, and everyone's eyes are focused on this Yun-8K aircraft.

"The plane has entered the designated runway!"

"Look, the plane is starting to accelerate!"

"Wow, that's fast!"

"yes, that's fast!"

Everyone was full of interest, and while watching, they exclaimed from time to time that the test flight of this Yun-8K completely changed everyone's consistent understanding and long-term understanding of Yun-8.

Li Tianfeng also smiled when he saw this. The power of the engine is strong, and it is already reflected in this moment. It's like a car, which used to have a 1.0 displacement engine, but now it has a 4.0 or even 5.0-liter large displacement engine.

We know that those world-famous sports cars can accelerate to 100 kilometers in just three or five seconds. This is because there is a powerful engine, which is basically the case with the current Yun-8K.

in the cockpit.

Several crew members glanced at each other, although everyone had fully understood the Yun-8K before the test flight, and also understood the basic performance of the turbofan 16 engine, but everyone's mental preparation was still insufficient.

Now, it has not been pushed to the maximum throttle position, that is, the engine has not yet played to its maximum power. However, the whole aircraft is already in a state of acceleration, and the speed climbs sharply.

"Xiao Li, push to the maximum throttle position and get ready to take off!"

"Yes!"

Xiao Li decisively pushed the throttle to the end and pushed it to the maximum throttle position, and the two turbofan 16 engines also reached the take-off state, that is, the maximum power state. Xiao Li's first feeling was that he seemed to be deeply trapped in the seat.

This is because the acceleration is very large in the table xiàn. The planes also galloped on the runway, completely like wild horses on the loose.

"Take off!"

Seeing that the take-off speed had been reached, as the captain, he immediately shouted, then pulled up the operating stick and transported the 8K plane off the ground. Fly towards the blue sky.

"Look, look, it's flying!"

Everyone looked at the Yun-8K plane that left the ground, and the plane left the ground and was climbing rapidly in everyone's eyes. Fly towards the blue sky.

"Oh my God, this runway is at least a third less than it used to be."

"I don't think that's all, I used to have to run almost two thousand meters to take off, but this time it's definitely just over a thousand meters."

"It's so fast, it's so cool!"

Everyone watched the Yun-8K plane fly into the blue sky, and soon, many people found out that it was different from before, in everyone's impression, the Yun-8 plane flew into the blue sky, dragging four faint black smoke behind it, this is because of the insufficient fuel burning.

And this time, where there is no black smoke, there is no black smoke at all, the fuel is in the turbofan 16 engine, fully burned, the fuel has been fully utilized, after combustion, the emission is basically water vapor and carbon dioxide.

"Look, there's no black smoke behind the plane!"

"yes, it's completely different from before!"

Everyone looked at this Yun-8K, until this Yun-8K flew into the air, flew into the distance, and disappeared in everyone's sight, even if the first test flight has not been completed, but the moment the plane disappeared in everyone's eyes, thunderous applause rang out!

The applause was loud and it took a long time to stop!

Minister Liu even said: "Mr. Li, you gave us a big surprise, without such an excellent engine, there would be no Yun-8K now!" ”

Li Tianfeng said modestly: "Minister Liu, you have won the award, this is what we should do, and it can be regarded as a small contribution to our national defense cause." ”

Minister Liu glanced at Li Tianfeng approvingly, and thought in his heart, young people are not arrogant or impatient, not bad, not bad!

In the sky, above the Y-8K plane.

The plane flew into the blue sky, everyone looked at the instrument, the flight altitude was 10,000 meters, the cruising speed was Mach 0.8, the plane was unusually stable, the engine was working normally, and it was in a small rated power state.

"Head, this plane is so cool to fly, you see, how stable and comfortable!"

"yes, it's basically no longer the noisy engine sound that it used to be, it's really comfortable!"

"Head, the moment I took off just now, it was even cooler! It was a big surprise to fly so quickly! ”

"It can fly in such a short time, our Yun-8K can take off and land in many places, even if it is a small airport, a short runway can fly."

“……”

Everyone while driving the Yun 8K, while chatting happily, according to discipline, there is little chat during the flight, but today is different, everyone's surprise is really a little big, happy to chat, and still chatting about the engine and Yun 8K things, normal!

According to the test flight regulations, flying to an altitude of 10,000 meters, flying in a cruising state for half an hour and then returning home, because it is a transport aircraft, those thrilling actions, such as inverted flight, climbing at a large elevation angle, diving and other actions are possible, that is what fighters have to do.

This Yun-8K flies at an altitude of 10,000 meters, the watch is unusually stable, and it is also very comfortable to drive. For everyone, there is no deafening engine sound.

Of course, there must be a sound from the engines, which is much quieter and calmer than the previous four turboprop engines, and it sounds better.

Follow the scheduled route. The Yun-8K flew at high altitude, and also maintained radio contact with the ground control tower, and the flight was normal, and the time passed minute by minute.

After half an hour of cruising and time passing relatively quickly, the plane flew in a large circle in the high altitude and began to return and fly towards the airport.

The plane began to return, and the pilot Xiao Li looked at the fuel gauge. couldn't help but look puzzled, as if he had found an abnormality, and hurriedly said: "Head, look at the fuel consumption, it's too abnormal." ”

The middle-aged pilot also looked at the fuel gauge and then at the fuel indicator, and was slightly strange in his heart, but he saw that the instrument was normal. The fuel indicator light also didn't come on, and I couldn't help but think about it. And then the road.

"Xiao Li, fuel consumption is normal, don't worry."

"Head, this fuel consumption is much smaller than before, I remember the old Yun-8, four propeller engines. Fuel consumption is much more than this. ”

"Perhaps, this is because it has been changed to two turbofan engines, and the fuel consumption is small, and our Y-8K range will increase a lot."

This is also the truth, the previous fortune eight. The power is four turboprop engines, because the fuel utilization rate is relatively low, the range is only more than 3,000 kilometers, which is a bit short for military transport aircraft.

After the modification of two turbofan 16 engines, the fuel efficiency is greatly improved, after all, the fuel efficiency of the large bypass is much higher than that of the turboprop engine, and correspondingly, the range is also increased a lot with the same amount of fuel.

The previous maximum range of the Y-8 transport aircraft was more than 3,000 kilometers, but after the modification of two turbofan 16 engines, the range almost doubled, approaching 6,000 kilometers.

"Attention, everyone, start landing!"

After speaking, Comrade Captain pressed the control stick, and the speed of the plane began to decrease, and the altitude also began to decrease, and it flew towards the designated runway of the airport.

"Look, look! Our Yun Ba K Shun lì returned! ”

"That's right, it's really our YunbaK!"

Seeing this plane, everyone looked up at the plane that was getting closer and closer, at the beginning, the plane was just a small black dot, this small black dot gradually became bigger in everyone's eyes, and soon, everyone recognized that this was the test flight of the Yun-8K.

The altitude is further reduced, lower and lower, the landing gear of the aircraft is opened, aimed at the designated runway, and the tires on the landing gear come into contact with the airport runway, making a screeching sound, because of the friction, raising a faint cloud of smoke and dust.

The plane landed smoothly!

Yun-8K taxied on the runway, gradually smoothing down, the speed became slower and slower, and in the eager eyes of everyone, the plane finally stopped steadily.

"Oh also! Our first test flight was a complete success! ”

"Wow, that's so happy!"

Seeing this scene, many people whirred and jumped up, and some ground crews and technicians ran towards the plane to inspect the plane after the test flight.

At the same time, an infantry fighting vehicle slowly drove over and drove towards the Yun-8K, and the tail hatch of the Yun-8K also slowly opened, and the infantry fighting vehicle actually slowly drove into the cargo hold of the Yun-8K aircraft.

"Is there still a test flight?"

"Definitely, the first test flight was a complete success, but there was nothing in the cargo hold, this time, after loading our new infantry fighting vehicle, we will have to test it again."

Everyone saw this infantry fighting vehicle slowly driving into the Yun-8K, and the whole scene gradually quieted down, and everyone's eyes fell on this Yun-8K transport plane.

Today's three watches, the third one is sent!

Early in the morning, the shell family went to the Ethereal Temple, and as soon as they came back in the afternoon, they began to code words, and they have not stopped until now, and they haven't eaten dinner yet, and finally they are finished and can have dinner.

In addition, I would like to ask for a commuter pass and recommend the support of the ticket! (To be continued......)
