Chapter 1398 Isn’t it really an alien technology, right?
Autumn goes and winter comes.
Time soon came to the last day of 2008.
Huangtianba Airport in the western suburbs of Rongcheng.
As the night gradually enveloped the earth, the navigation lights on both sides of the runway were stained with an orange-red halo under the refraction of fine ice crystals.
More than a dozen technicians from Rongfei Group were gathering next to a camera. The leader was wrapped in the collar of the military coat and looked at the dusk mid-air with a worried look.
It was Yang Wei, the chief designer of Project 20.
For confidentiality considerations, large-scale transportation related to the development of new-generation fighter jets is basically arranged to be carried out at night.
But now it is true that the weather is not good.
When the meteorological department suddenly announced that it would cool down and fog, the transport plane responsible for transportation tasks had already taken off from Shengjing.
If the meteorological conditions at the airport are too poor, you can only choose to land or return.
"Mr. Yang, the current temperature is -5℃, and the ground clearance work has been completed. The runway with the light on is about 350 meters. The pilots of both aircraft believe that the landing conditions are met and there is no need to go to the Nanjiao Airport of Fucheng to prepare for landing."
Wang Chengyao, assistant to the chief officer, jogged from a distance, handing over the thermos while reporting the situation.
After hearing the conclusion that "no need to make a reservation", Yang Wei finally felt relieved.
But just as soon as I unscrewed the cup lid, I raised my concerns in another direction:
"You didn't put pressure on the pilot during the communication, did you?"
He watched the steaming heat condense into white mist above the mouth of the cup, and confirmed to Wang Chengyao:
"If there is any risk, you don't have to force it..."
Seeing that the chief stern, who was as stable as Mount Tai, now also looked worried about gains and losses. The latter wanted to laugh a little, but under the gaze of the big bosses around him, he didn't dare to laugh. He just shook his head: "It's all the tower commanders communicated, we didn't make any noise at all... Besides, the No. 5 and No. 6 of the Air 37 Regiment have not been here for the first time. We should be very familiar with the situation and will not take risks..."
Civil aviation's visibility requirements for landing 80-100-ton twin-engine aircraft in Chengdu are that the runway visibility range is not less than 550 meters, but this figure obviously leaves very sufficient redundancy.
Yang Wei's lips moved, as if he wanted to say something, but he still didn't speak in the end.
The daily training of transport pilots includes blind landing with low visibility, and the runway of Huangtianba Airport is not used by other aircraft, so the take-off and landing conditions must be more relaxed.
At this moment, a roar of the engine came from mid-air.
Then the lights on the landing gear and the wings penetrated the mist, forming a clear column of light under the influence of the Tindal effect.
It was not until the last moment before the ground touched the ground that the light gray fuselage of the transport aircraft gradually showed its full view. The fully opened speed plate and wheels opened their teeth and claws, like a beast breaking through the seal.
This latest dual-engine medium-sized transport aircraft has only been officially equipped with the troops for about a year, and is especially equipped with brand new power. According to the rhythm of the past, it should still be in the replacement stage, and there will be certain restrictions on flight parameters such as load load, take-off and landing conditions and range.
However, the sudden disaster relief demand in the first half of the year disrupted all the step-by-step plans. Almost all moving transport aircraft in the army were dispatched in turn to be responsible for airdropping materials or transporting personnel and equipment.
Finally proved that the Y9 has a higher dispatch rate than the Y8 and even the Il76 and a lower direct maintenance work hours per flight hour. Under high-intensity flight operations, it can even approach the level of civil aviation passenger aircraft.
Most Y8s are of course old guys over ten years old and have no reference value, but many of the Il 76s are newly produced within 5 years.
In this way, the new model is equivalent to directly passing the adaptation period, and the two troops that were the first to eat crabs instantly became popular and began to gradually undertake the main transportation tasks of medium loads and distances.
…
At the same time, in the cargo hold of the second No. 06 machine behind, Liu Yongquan was seeing the huge hangar at the end of the runway slowly unfolding through the ice flowers condensed on the porthole.
Not far behind him, a turbofan 10G engine with an air inlet wrapped in anti-static camouflage cloth was fixed on a special transportation bracket, and the silver-gray tail nozzle shell was shining cold under the dim cabin light.
In fact, in terms of the load capacity and capacity space of the Y9, two engines and less than twenty technicians only need one order to complete transportation.
It was only for the sake of risk sharing that two aircraft were specially arranged.
This is certainly not the first time Liu Yongquan came to Rongfei, but it is the first time he brought a model designed by himself to hand over it.
It is completely different from the experience of simply communicating work in the past.
He was even a little impatient to see the new model be installed on the new generation of stealth fighter that is about to be tested. Chang Haonan once mentioned at a meeting that when the project 20th was officially launched four years ago, his colleagues in the aviation industry were ready to continue to use the turbofan 10A on the first batch of mass-produced models.
But now, the adaptation of the new version of power has been completed just in the technical verification stage.
In fact, if it is not for sufficient comparison data, then there is even the condition to directly use the new engine to make a first flight.
A few minutes later, the vibration of the transporter tire touching the ground interrupted his thoughts.
The moment the hatch door opened, the wet and cold air was swept into the cabin with the smell of aviation kerosene and metal processing liquid, making Liu Yongquan, who had just untied his seat belt, feel a little uncomfortable.
For those who have worked in Northeast China for a long time, the temperature of -5℃ is of course nothing, but the water vapor that is so rich that it is as solid, it brings considerable breathing resistance.
It's like wearing a layer of mask for no reason.
"Old Liu!"
Before he was fully accustomed to it, a sound penetrated the low roar of the engine at idle state.
Liu Yongquan looked out along the hydraulic tailgate that was being opened and found that Yang Wei, who was wearing an old military cotton jacket, was waving to this side. Seven or eight other technicians behind him were following a dedicated transportation platform tractor.

"You are here at the right time. The 2003 aircraft is waiting for these two hearts..."
He said hello and directed the technical team to start unloading the engine.
Liu Yongquan habitually stamped his feet to keep warm, but the cold in the southwest was an illusion rather than a real low temperature, so these two moves made his legs, which were already fine, numb.
He suddenly felt that this scene was a bit similar to a classic Spring Festival Gala sketch.
You stomp your body and you will be irritated.jpg
So he changed the topic a little embarrassingly: "By improving the manufacturing process, it is 27 kilograms lighter than the initial design indicator."
He glanced over the lifting platform where he was working. Workers are calibrating the engine hanger with a laser positioner: "To be honest, we have also learned a lot from the British in recent years... The fourth generation of single crystal materials combined with the newer generation of active cooling technology in the past can withstand a gas temperature of up to 2050K. In addition, the full state compressor after adjustment finally makes the thrust-to-weight ratio under the ideal sea level reach a real double digit... Lao Yang, this time we finally don't need to subtract the thrust on the thrust."
Yang Wei stopped when he heard this and was about to sign, and a complex look flashed through his eyes when he looked up.
When they were demonstrating Project No. 10 twenty years ago, they even considered using a turbojet engine to make do with it. Later, they found Russian braking power that meets the conditions, but they heard the other engineer say in broken Russian English, "It will take at least five years."
The tingling pain is still hot in my memory.
Now, the two engines in front of us that embody the latest domestic technology are being carefully transported to a special flatbed truck, combined with the aerodynamic design that is almost attained by the realm of perfection...
A moment of satisfaction flashed in Yang Wei's heart, but he was immediately replaced by vigilance.
The most taboo thing in doing projects is blind optimism.
"When I think about it this way, Americans can produce the same data 10 years ago. I really don't know how to make the technology..."
This sentence is half a chat with the other party, and half a reminder of themselves.
It's still far from relaxing.
Liu Yongquan was also resonated with a lot of resonance, and he couldn't help but recall the nights that had been fighting nights in the past few years.
"The engineers on Rollo once told me that they had shared the most advanced material technology of this era."
He suddenly said something that seemed to be unrelated: "Overall, I think even if there is moisture in this sentence, there is probably not too much..." Yang Wei handed over the signed transportation documents to the assistant behind him, and then looked at Liu Yongquan with a puzzled look, as if he didn't understand why he suddenly mentioned these.
The latter put the teeth on the back and explained further: "So the performance of the turbofan 10G has almost reached the physical limit of this era... But just as you said just now, it is just around the corner with F119."
Then take a deep breath, and keep silent: "You said that there are no aliens in that area 51, right?"
