Chapter 1408 No. 2001, take off!

Chapter 1408 No. 2001, take off!

Early morning on April 2009, 2.

Huangtianba Airport, western suburbs of Chengdu.

When Chang Haonan's last Falcon 8Z plane landed firmly on the south apron, the entire maiden flight ceremony was already ready.

After the Challenger 601, which was originally unpopular in the last century, the Chinese government's special aircraft series operated by the 34th Air Division basically gave up the purchase of business jets. Instead, they directly allocated ordinary passenger planes such as Airbus A320 or C909 from airlines and used them to carry out VIP transportation tasks after slight modifications.

However, the Falcon X series is, after all, a benchmark product jointly developed by China and France. Dassault also promised to keep part of the final assembly tasks directly in the Luzhou Aviation Industry Park, which has already begun to take shape. China still purchased a batch in the official name, just to express its support for the project.

However, after actually using it, I found that this model is actually much larger than the Challenger 601, which had received a lot of negative reviews. It is almost close to the level of some regional airliners. The cabin does not feel as cramped as the latter, and it also has an absurdly long range considering its size.

Although the specifications still cannot meet the needs of high-ranking leaders' visits, it is very suitable for medium-level and small and medium-sized delegations, saving the waste of dispatching Boeing 757 or even Airbus A330 to transport a dozen or even a few people.

So it was not surprising that it tasted really good in the end.

Not only were the second and third batches purchased successively, but corresponding modification requirements were also made directly when they left the factory, making it an aircraft similar to the US Air Force C37A/B, which is specifically responsible for small-scale VIP transport missions.

After all, most of the processes of these Falcon 8Zs, from production to final assembly, are completed domestically, so there is no concern about someone installing eavesdropping devices or even flight safety backdoors in advance.

However, this also brought some side effects.

The reason why Chang Haonan was able to monopolize the Challenger 601 and fly around in the past was mainly because no one else was willing to sit on it except him.

But now the new plane has changed from Mrs. Niu to Sweetie, so he often has to share a plane with others.

Of course it has no impact on the trip itself, but sometimes it is still inconvenient.

Just like today.

In fact, when he was in mid-air just now, he had already noticed that there were not one but two planes with big red flowers hanging on the tarmac, but after all, there were leaders from outside the aviation industry system present, so he had to keep his words to himself.

Until the moment the hatch opened.

The damp and cold wind blew in the face, carrying the unique smell of aviation kerosene. On the other side of the apron more than a hundred meters away, two J-20 verification aircraft were like dormant silver dragons. The red star on the vertical tail of aircraft No. 2001 still reflected the new paint, while the other one was still in the stage of being completely black, but the vaguely visible dark gray tail nozzle still indicated its identity.

Verification aircraft No. 10 equipped with WS-2003G

Yang Wei and Liu Yongquan were smiling and welcoming everyone at the bottom of the gangway.

"I remember the report I received earlier said that the WS-10G comparison test was scheduled for next month?"

After a brief greeting, Chang Haonan asked directly.

Because he was not directly responsible for the overall development of the WS-10G, he could only rely on written reports to understand the progress of the mission in most cases.

What's more, there is a layer of separation between WS-10G and Project No. , so it is inevitable that the information is not updated in a timely manner.

But Yang Wei shook his head:

"The test flight plan has not changed, but when our superiors gave us instructions, they specifically mentioned 'prepare to welcome the American delegation with great enthusiasm', so we decided to bring No. 2003 out to participate in the ceremony..."

Then he looked towards the entrance of the apron in the distance:

"Besides, it looks better if it's arranged like this..."

The two planes were parked at a 45° angle relative to each other, one on the left and one on the right, and both had their canards adjusted to the maximum pitch angle to show their welcome to the guests and, of course, the "international friends" far away in Beijing.

Chang Haonan heard this and shook his head helplessly:

"You guys always come up with something new for me..."

Then I looked at my watch and it was exactly 9:15 in the morning.

"The American plane should have landed by now. According to their satellite reconnaissance frequency and analysis efficiency, we will probably receive relevant information after the first round of talks this afternoon and before the dinner."

Of course, it only takes a split second for a satellite to take a picture, but the efficiency of analyzing and transmitting information by departments at all levels is not that fast. In addition, it is probably just nightfall in the United States now, so the efficiency will be further discounted.

After comprehensive analysis, 6-8 hours is a more reasonable range.

However, Liu Yongquan, who had been silent just now, smiled mysteriously:

"Boss Chang, actually, on the 25th of last month, we had already pulled out No. 2003 to do an outdoor launch. They must have noticed something, but the conditions at the time were not good enough for us to make a judgment... With such a big event today, our American friends should be able to receive the surprise almost immediately..."

The three of them looked at each other, and then laughed out loud at the same time.

……

While Yang Wei was talking, Liu Yongquan came up to Chang Haonan:

"Mr. Chang, regarding the HDK305 coating material..."

They were arranged to sit separately on the podium, and Yang Wei's voice was echoing everywhere in the venue, so as long as they didn't plot loudly, there was no risk of leaks.

"Still studying..."

Chang Haonan replied:

"It has been preliminarily determined that this material, after being magnetized in a specific way, does have the ability to selectively absorb infrared signals in the atmospheric window band... But you mentioned earlier that Lao Yang wanted to achieve a high level of infrared stealth by coating the entire aircraft with this material, which is not easy to achieve for the time being."

Liu Yongquan didn't show any emotion:

"So, is there really a problem with the weight and adhesion?"

Chang Haonan hesitated for a moment:

"Weight and adhesion are only part of the story... I asked Researcher Peng from the Institute of Aeronautical Materials. Although they came up with this material by chance, it can improve my theory on microscopic molecular computing to a considerable extent, and there may be room for improvement in the future."

"The problem is that the infrared signal absorption of the HDK305 coating is in the form of a threshold, not a percentage. So it works well near the high-temperature tail nozzle and plasma layer, but it is completely redundant to apply it to the surface of the aircraft, which is not hot in itself... On the other hand, if the molecular structure is specially modified on this basis, the cost of the improved material will probably increase to an unimaginable level, and it will definitely be used in more important places..."

Liu Yongquan was a little confused for a moment:

"There are things more important than aviation engines...but aren't we the Aviation Power Group?"

"Uh……"

Chang Haonan found it a bit difficult to explain:

"After all, I am still the chief consultant of the Construction Committee. I still have to consider the problem from a comprehensive perspective..."

In fact, what really surprised him about this material was the refractive index.

If negative refraction can be achieved on a transparent material in the future, it will almost be equivalent to a subversion and reconstruction of the entire optical industry.

However, up to now, Li Yabo has not been able to stably figure out the conditions for negative refraction or zero refraction.

The latest novel is published first on Liu9shuba!

Fortunately, before Liu Yongquan could continue to ask questions, the voice of the host came from the radio.

"Dear guests, the time for the first flight is approaching. Please take your seats on the viewing platform according to the numbers on your ID cards..."

Due to time constraints, the top leaders were either on a visit abroad or in Beijing receiving guests from other countries today, so although the maiden flight site was grand in layout, there was not too much red tape at the ceremonial level.

At the same time, test pilot Li Gang, wearing the latest green anti-gravity suit, has stepped into the cockpit of aircraft No. 2001 and began to complete the final preparations before launch with the assistance of ground crew.

Chang Haonan looked up behind the viewing platform, where there was a remote sensing monitoring vehicle disguised as a freight truck. Of course, it now had many antennas sticking out, and it didn't look like a civilian vehicle at all.

Yang Wei, who had just returned to his seat, also reported:

"The monitoring vehicle just reported that it has captured space-based SAR signals from four different angles. Add to that the optical reconnaissance satellite that is currently passing overhead. I'm afraid there are at least a dozen eyes staring at us..."

"It's better to have some fun..."

Chang Haonan raised the telescope and looked towards the end of the runway.

Staff are removing the red silk from the two J-20s.

What is different from all previous test flights is that the power supply vehicle and the air supply vehicle were just on standby but were not connected to the aircraft fuselage.

At ten o'clock in the morning, as a faint flame spurted out from the APU exhaust port located on the upper rear of the fuselage, the auxiliary power unit of aircraft No. 2001 suddenly made a crisp puffing sound, instantly attracting the attention of everyone present.

Immediately afterwards, the low roar from the two engines completely tore apart the originally silent air.

A few minutes later, without the assistance of a tractor, the plane slowly drove onto the taxiway under its own power.

The first flight is always a dangerous task that involves walking on the edge of a knife.

However, with the continuous development of aviation technology, the psychological pressure of the first flight of Project 20 is undoubtedly much less for both test pilots and technicians than it was more than a decade ago.

When passing in front of the viewing stand, Li Gang pulled the brake handle, making the plane nod in front of the crowd, and then stopped steadily at the take-off preparation point.

Earlier, a two-seat J-10S used for escort had taken off and was now circling over Huangtianba Airport.

When the number on the electronic clock reached 10:25, the roar of the No. 2001 engine suddenly increased, and the tail nozzles of the two turbofan 10A engines were adjusted from expansion to convergence.

Half a minute later, Li Gang in the cockpit took a deep breath, released the brake handle, and let the seat back push him forward.

As I looked, the distance markings on both sides of the runway kept moving backwards.

Compared to older models, this aircraft has reached a whole new level of complexity.

But for the driver, it feels like returning to nature.

Almost all operations are intuitively displayed on the two oversized screens in front of you; even the abbreviations in the system prompts are in Chinese characters.

For example, at this moment, the pilot does not even need to judge the taxiing status by feeling, because there is a lift diagram on the far left of the screen, which is gradually turning from yellow to green starting from the nose part as the speed continues to increase.

When the nose of the plane passed the "350" mark, the overhead view of the entire aircraft turned completely green, even about one second earlier than Li Gang himself felt.

He then pulled the lever.

Through the surround-view system that was spread all around the fuselage, Li Gang saw the tail flame from the engine hitting the runway.

The image is slightly distorted due to refraction caused by the hot air.

It looked like a flower blooming under flames.
