"You know everything? Aren't you worried? Lao Zhou looked at Gu Tingting strangely.

"Of course I'm worried, but what's the use of worrying?" Gu Tingting said: "Instead of worrying about these distant things, it is better to hurry up and release our plane." ”

How can you not be worried? I heard that this first flight is definitely a life of nine deaths, but what, because of the risk, don't you let Qin Feng go? That's his mission!

Gu Tingting's mood is complicated, especially, in addition to her lover, now even the little tiger head has begun to show a tendency to fly, and in the future, I am afraid that I will have to worry about the flight of two people!

"I've already asked, Brother Feng is safe and sound, and he laughed at me for making a fuss." Just then, another voice came.

Tang Gang.

Originally, this plane was intended to let Qin Feng fly, but when it was about to make its first flight, Qin Feng ran to fly the J-7, so this aircraft can only find other people, although Tang Gang has not been in contact with test flights for a long time, but he is almost Qin Feng's apprentice, especially, test flights of this new aircraft, what is needed is a scientific research test pilot, Tang Gang has grown very fast in this regard.

Looking at him now, he is still holding a thick notebook in his hand, which records all the information and data, and Tang Gang is also quite familiar with this aircraft.

This comes from his hard work, he has understood the whole design principle, the whole architecture, although he doesn't understand the detailed software code, but how to fly the experience, how to improve, he can analyze the head of the way, because, on the simulator, he has practiced thousands of times.

He also cared about Qin Feng, after learning about the first flight of the Jian-7, he was the first to call and inquired about Qin Feng's situation in detail, and after learning that there was no problem, he came back with peace of mind, and just heard the two of them discussing, so he quickly told Qin Feng's situation.

"Yes, no matter what the failure, Qin Feng can fly the plane back, we have to have confidence in him, besides, the J-7 is in the 172 factory, that is, it will fly until next year, and it will come to our test flight institute to fly the follow-up subjects." Lao Zhou said.

Wait another year, the follow-up test flight, will come to the most scientific and experienced test flight institute, when the time comes, Qin Feng will be able to be with Gu Tingting, hearing this, Gu Tingting is also looking forward to it for a while, yes, I really hope to next year soon!

However, it's useless to think about this, let's look at the plane here, this BW-1 has been refreshed, painted with the number 008, this plane, in everyone's mouth, is directly called 008.

"Let's get ready for our ground slide." Gu Tingting said.

For the sake of the aviation industry of the motherland, I don't know how many people are constantly fighting.

Now it is the middle of winter, the earth is cold, the sky is even colder, an An-12 transport plane, is flying in the sky, inside the cabin, a large number of electronic equipment, constantly emitting heat, but from the back door poured in a cool breeze, so, one side cold, the other side of the heat, quite uncomfortable.

However, inside the plane, no one complained, they were all staring at the instruments and equipment in front of them.

"Low-frequency pulse mode, ready for Doppler filter clutter experiments." Ben Lao also got on the plane on this day, because, some time ago, the fault was almost eliminated, and now, they are going to carry out real pulse Doppler experiments.

This 1471 radar, they have almost done it, and now, it is the most critical time!

With the flip of one experimental switch after another, a powerful current enters the magnetron of the radar, radiates through the flat plate slot antenna in front, and countless electromagnetic waves fill the ground in front.

Countless echoes returned like a galloping horse.

Domestic fighters, up to now, can not achieve downward firing, the most important thing, is that there is no such pulse Doppler filtering ability, now, the 1471 radar is a breakthrough in the domestic radar!

Everyone is looking forward to it, the program data has been debugged countless times, and now there will be no problems, right?

A large amount of clutter is reflected back and enters the processor behind it, starting a high-speed Lorentz transform, and those ground-based fixed targets, because they are not moving, produce the same Doppler frequency change, and you can filter it out!

Finally, a large number of bright spots on the screen began to disappear, smaller and smaller, and finally, all the bright spots disappeared, and the clutter on the ground was filtered out!

"Success, success!" Countless people shouted excitedly, they had worked hard for many years for this radar, and now, finally, the clutter on the ground was filtered out! Although because of hardware problems, it can only be low-frequency pulses, and there is still a big gap from real practicality, and more advanced digital and analog conversion circuits and faster processors are needed, but at least, now they have done it!

For the first time, the clutter on the ground was filtered out in their hands!

Qin Xue wiped her nose with her hand, her position happened to be poured in by the cold wind, so she caught a cold when she was blown by the wind, but she still insisted on participating, and now, with such a wipe, the snot was wiped on the cuffs, for a girl, such an approach was too sloppy.

However, at this moment, a handkerchief was handed over: "Here you go." ”

Although Zhiqiang's family conditions are not good, although he is usually a wooden person, but, in many cases, it will reflect that unique care, holding this handkerchief, Qin Xue felt happy, she wiped all her snot on it, and then, Zhiqiang wrapped it very carefully, put it back in his big pocket, and took out a new one.

Sometimes, love is so simple and so natural.

"Comrades, I'm the captain, and now report bad news, our wings are icing. So, we may suddenly drop heights, I hope you don't be afraid. Just then, a voice broke their excitement.

Their experiments were successful, and this was a breakthrough in the history of airborne radar! But, unfortunately, the wings froze!

Although the heating wire for de-icing has been turned on, the ice is still getting thicker and thicker, and the wings were supposed to provide lift, but now after the ice, not only can they not provide lift, but also begin to increase the weight, so the An-12 transport aircraft can no longer maintain, the wings are getting heavier and heavier, and suddenly, they begin to fall downward, like a big rock!
