The improved new engine was finally named WS-10S, and the reason why it was not positioned as WS-10A was because Chen Nian felt that the name was not very auspicious, so he gave Lin Yongming advice, and in a limited range, he was a little willful.

However, this engine is also worthy of the "S" on the suffix.

The comprehensive performance is actually stronger than the AL-31FN, and there is even a vague intention to catch up with the F119!

If those people in the 606 Institute were allowed to do research and optimization for a period of time, wouldn't the F119 project be cancelled directly?

---- but of course, it's just a joke.

In fact, there is an essential difference between F119 and WS-10 in terms of technical concepts, most of the technical sources of WS-10 still come from Russian-made engines, and they take the path of great ingenuity, which is why after the material upgrade, the performance of the engine will be improved.

And what about the F119?

Whether it is in the refined structure, or the leading internal structure, or the tolerances strictly controlled by the process process, in fact, it is a new field for Huaxia.

If you eat this engine thoroughly, the help for Huaxia Hangfa technology is actually much higher than improving a WS-10.

Therefore, even though the results of WS-10S are amazing enough, the F119 project is still proceeding step by step, and the entire project team is busy revealing a faint calmness.

In contrast, the ground and high-altitude tests of the WS-10S were completed with vigorous and resolute efficiency, and then in the shortest possible time, the J-10 was boarded, the flight control was adjusted, and the first test flight was about to be carried out.

The test flight site is at the 601 test flight site......

......

In the early morning of February 1, Shenfei test flight field.

Chen Nian yawned and walked down from the jeep, followed by Chen Guo, and Lei Gang and Wang Xianguo, who had been waiting for a long time, immediately dropped the report in their hands and greeted him as soon as they saw him.

"Xiao Nian, here? How about it, I haven't slept all night, and I can still hold on, right? ”

Chen Nian barely squeezed out a smile and replied:

"It's okay, I slept on the plane for a while and it's okay now."

In fact, including him and Chen Guo, they didn't receive the news that the new Jian-10 test aircraft equipped with WS-10S was going to make its first flight in space until the night before.

According to Lin Yongming, most of the technology of this engine comes from Chen Nian, who can almost be said to be his child, and he is not present at such an important moment, so he can't say anything.

When it came to this, Chen Nian couldn't refuse, so he had to go to the airport in the middle of the night with Chen Guo to take a special plane, flew for more than three hours, and after landing, he turned to a jeep and ran for more than an hour, and finally arrived at the test flight site before Jian-10 took off.

"There's no way to be sleepy, after all, it's the first flight, you still have to come and see."

"If you have a selfish intention, if something goes wrong at that time, you can solve it here."

"Most of the technology comes from you, even Xianguo is a setter, with you, we can feel a lot more at ease."

Lei Gang said half-jokingly.

Hearing this, Chen Nian hurriedly waved his hand, he smiled at Wang Xianguo, and then said:

"Lei Gong, what you said is too heavy...... I just gave an idea and direction, isn't the actual application still made by our researchers? ”

"Don't hold me up too high, I look very rusty."

"Hahaha, you don't wear a thousand sycophants. Okay, let's not tell you that this is useless, according to the plan, our side will take off in 10 minutes, and now we are doing refueling and pre-takeoff checks, do you want to go and see? ”

Chen Nian hesitated for a moment, shook his head and replied:

"Don't look at it, it's progressed to this point, basically all the problems that can be seen have been solved, and I'll just pretend to be there, there's no point."

"It's better to stay here honestly, so as not to make the work of the comrades in the intelligence department difficult."

Lei Gang nodded approvingly and continued:

"Mr. Lin didn't come today, you know, he's busy with things over there, although the things you studied before are basically owned by the army, but our AVIC is the leader, and he has more things."

"The day before yesterday, he had already entered Beijing for a meeting, and before leaving, he specially told me to tell you, the original words are to say, even if something goes wrong, so that you don't have psychological pressure, if you succeed once, I will take you to relax and relax."

"Relax...... Let's talk about it. The refueling truck has withdrawn, Mr. Lei, it's about to fly, right? ”

"Come on, let's go, let's go to the command platform!"

As soon as Lei Gang waved his hand, the group followed his footsteps to the command platform, and at this moment, the headset of the command platform faintly came from the password prepared before taking off.

"Check the flaps, the flaps are normal."

"Navigation is normal, pressurization is normal."

"The avionics are working fine, the radar is working properly."

"The engine warms up normally and idles normally."

......

"Check-in, No. 01, request to take off!"

Hearing this, Lei Gang turned his head to look at Chen Nian, who nodded slightly, and then, a sonorous and powerful command came out of Lei Gang's mouth.

"No. 01, permission to take off!"

When the words fell, a huge roar sounded, and the tail of Jian-10 Test Aircraft No. 01 erupted with blazing bright blue flames, and the Mach rings circled one after another were like star rings, spreading backwards in a rippled shape.

Immediately after that, the plane began to taxi on the runway at an extremely high speed, and after a distance of less than two hundred meters, the nose of the plane suddenly pulled up, and the whole plane rose from the ground!

"it...... So strong? ”

Chen Nian was stunned as he looked at the plane that was gradually taking off, and the shock in his heart was indescribable.

Yes, he had already seen the data about this engine, but the cold numbers were still too thin compared to the intuitive experience of standing on the scene.

The sand and heat waves blown up by the strong wind are the best illustration of the true strength of this engine.

Hearing his words, Lei Gang said with a little pride:

"Isn't that right? Now there is still room for improvement in this J-10, and if some aerodynamic optimization is done in the later stage, it is not a problem to compress the take-off distance to within 200. ”

"When the time comes, with the sliding platform, we can even get on the aircraft carrier directly!"

Aircraft carrier...... Not to mention the aircraft carriers that can be used in the current Huaxia, the Varyag, which was finally bought, is still about the same as scrap iron, and it seems a little too far to say this.

----However, Chen Nian, the butterfly, has already flapped its wings, and who can say clearly at what speed the Huaxia Military Union will develop in the future?

Thinking of this, Chen Nian shook his head, gathered his slightly chaotic thoughts, and looked intently at the fighter plane in the air.

In fact, when the test aircraft goes into the sky for the first time, it will most likely not do any dangerous or extreme operations, and will only fly around the test site a few times in accordance with the test flight procedure, and then it will start to land.

But today, things seem to be a little different.

During the test flight, which was supposed to be boring, the pilot was stunned and made several large-angle climbing actions in a row under the command of the ground, looking at the full arc of the track, Chen Nian sighed again:

"I'm ..... Is this the power of the bricks? ”

"This angle is almost like a cobra maneuver, I wonder if I can try the fallen leaves and ......"

"Falling leaves definitely can't be done."

Lei Gang laughed and explained:

"Of course, it's not the plane itself that can't do it, it's just that we generally don't do this kind of dangerous maneuver during the first test flight."

"This experiment is still mainly based on recording data, and we will do another optimization based on the test flight data when the time comes."

"When the second test flight comes, we should start testing extreme operations......

Chen Nian nodded, and secretly thought in his heart:

It's actually no problem to try it or not, because with this level of power optimization, it is a matter of time before you make a falling leaf drift.

And now...... As long as you can land, it's done!

......

As if to see through his pretending to be calm, but in fact he was nervous in his heart, the Jian-10 in the air completed the various items of the first test flight at a very fast speed, and then, with an almost impeccable smooth movement, landed on the ground again.

The entire test flight site was jubilant.

"It's done! It's done! ”

"Damn, let's just say that our engine won't be bad, what AL-31FN, there will be no such thing as it in the future!"

"It's too strong..... The successor of the eighth master is finally here! ”

"606 Institute is really good, in such a short time, the effect is so good!"

"Nonsense, the main structure of our engines is all verified, and most of the tolerance ranges are less than 1/10,000, and if the effect is not good, there will be ghosts......"

Chen Nian stood aside and listened to the happy conversation of those researchers with a smile, he looked at the Jian-10 that the cockpit cover slowly opened, and couldn't help but have a thought in his heart:

It won't be long before the name of this fighter becomes known to everyone.....
