The improved new engine was eventually named WS-10S. The reason why it was not positioned as WS-10A as usual was because Chen Nian felt that the name was not very auspicious, so he suggested it to Lin Yongming. Within a limited scope, Xiao Xiao The land was willful.
However, this engine is indeed worthy of the "S" in the suffix.
The overall performance is actually better than the AL-31FN, and it even vaguely seems to be catching up with the F119!
If those at Institute 606 are allowed to do research and optimization for a while, wouldn't the F119 project be canceled directly?
----But of course, this is just a joke.
In fact, there is an essential difference in the technical concepts between F119 and WS-10. Most of the technical sources of WS-10 still come from Russian-made engines, which is the path of ingenuity and inefficiency. This is why after the material upgrade, , the engine performance will improve accordingly.
And what about F119?
Whether it is the refined structure, the leading internal structure, or the strictly controlled tolerances through the process flow, it is actually a completely new field for Huaxia.
If you understand this engine thoroughly, it will actually help China Aviation Technology much more 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 reveals a faint calmness in their busy schedule.
In contrast, the ground and high-altitude tests of the WS-10S were completed with resolute efficiency. Then, in the shortest possible time, they got on the J-10, adjusted the flight control, and were about to conduct their first test flight.
The test flight venue is at the 601 test flight ground...
...
In the early morning of February 1st, Shenfei flew to the test flight ground.
Chen Nian yawned and walked out of the jeep, followed by Chen Guo. As soon as Lei Gang and Wang Xianguo, who had been waiting for a long time, saw his figure, they immediately dropped the reports in their hands and came forward.
"Xiao Nian, are you here? How are you? You haven't slept all night, can you still hold on?"
Chen Nian forced out a smile and replied:
"It's okay. I slept for a while on the plane. I'm fine now."
In fact, including him and Chen Guo, it was not until the night before that they received the news that the new J-10 test aircraft equipped with WS-10S was going to take off for the first time. Originally, he did not plan to come, but Lin Yongming did. His name was called.
According to Lin Yongming, most of the technology of this engine comes from Chen Nian, and it can almost be said that it is his child. It cannot be justified that he was not present at such an important moment.
When the talk came to this, Chen Nian couldn't refuse, so he had no choice but to go to the airport with Chen Guo in the middle of the night and take a special plane. They flew for more than three hours. After landing, they transferred to a jeep and drove for more than an hour. Finally arrived at the test flight ground before the J-10 took off.
"There's nothing I can do about being sleepy. After all, it's the first flight, so you still have to come and take a look."
"To be honest, if there is any problem then, it will be easier for you to solve it here."
"Most of the skills come from you. Even Xianguo is a setter. With you here, we can feel at ease."
Lei Gang said half-jokingly.
Hearing this, Chen Nian waved his hands quickly, smiled at Wang Xianguo, and then said:
"Lei Gong, what you said is too harsh...I just gave you an idea and direction. Wasn't the actual application made by our scientific researchers?"
"Don't hold me too high and make me look very unfamiliar."
"Hahahahaha, you are wearing nothing but flattery. Okay, I won't tell you these useless things. According to the plan, we will take off in 10 minutes. We are now doing refueling and pre-takeoff inspections. What do you need? Don’t you want to go take a look?”
Chen Nian hesitated for a moment, shook his head and replied:
"I won't read anymore. At this point, basically all the problems that can be seen have been solved. If I go there, it's just a pretense. It's meaningless."
"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 in agreement and continued:
"Mr. Lin is not here today. You know, he is busy with export matters. Although the things you studied before were basically owned by the Army, our AVIC is the leader, and he has many things to do."
"He had already gone to Beijing for a meeting the day before yesterday. Before he left, he specifically asked me to tell you. The original words were, even if something goes wrong, don't put any psychological pressure on you. If it succeeds, I will take you to a good place. Go relax and relax.”
"Relax... let's talk about it. The fuel truck has withdrawn, Mr. Lei, is it about to fly?"
"Come on, let's go to the command podium!"
As Lei Gang waved, a group of people followed his steps towards the command podium. At that moment, the commands to prepare for takeoff came vaguely from the headset on the command podium.
"Check the flaps, they are OK."
"Navigation is normal, pressurization is normal."
"The avionics are normal and the radar is working normally."
"The engine warms up normally and idles normally."
...
"Inspection completed, No. 01, please take off!"
Hearing this, Lei Gang turned his head and glanced at Chen Nian, who nodded slightly. Then, a sonorous and powerful order came from Lei Gang's mouth.
"No. 01, permission to take off!"
After the words fell, a huge roar sounded, and the tail of the J-10 Test Machine No. 01 sprayed out blazing bright blue flames. Circles of Mach rings were like star rings, spreading backwards in a ripple shape.
Immediately afterwards, the plane began to taxi on the runway at a very high speed. After passing a distance of less than 200 meters, the nose of the plane suddenly pulled up and the entire plane rose from the ground!
"Fuck...so strong?"
Chen Nian stared dumbfoundedly at the plane that was gradually taking off. The shock in his heart was beyond words.
Yes, he had indeed seen the relevant data of this engine a long time ago, but compared with the intuitive experience he saw at the scene, the cold numbers still seemed too thin.
The dust and heat waves blown up by the strong wind are the best explanation of the true strength of this engine.
After hearing his words, Lei Gang said slightly proudly:
"Isn't that right? There is still room for improvement on this J-10. If some aerodynamic optimization is done later, it will not be a problem to reduce the take-off distance to less than 200."
"When the time comes and we cooperate with the ski jump platform, we can even board the aircraft carrier directly!"
Aircraft carrier... Let alone usable aircraft carriers in China now, the Varyag that was finally bought is almost like scrap metal. It seems a bit too far to say this.
----However, Chen Nian's butterfly has already flapped its wings. Who can tell clearly at what speed the Chinese Military Trade Union will develop in the future?
Thinking of this, Chen Nian shook his head, calmed down his slightly chaotic thoughts, and looked intently at the fighter plane in the sky.
In fact, there is a high probability that the test aircraft will not perform any dangerous or extreme operations when it takes to the sky for the first time. It will only fly around the test field for a few times according to the test flight procedures, and then it will start to land.
But today, things seem a little different.
During what was supposed to be a boring test flight, the pilot made several large-angle climbing movements in succession under the command of the ground. Looking at the curved flight path, Chen Nian sighed again:
"Holy crap...is this the big brick flying?"
"This angle is almost the same as the Cobra maneuver. I wonder if I can try Falling Leaves..."
"Floating Leaves Definitely can't be done."
Lei Gang laughed and explained:
"Of course, the failure is not a problem with the aircraft itself, but we generally don't engage in such dangerous maneuvers during the first test flight."
"This experiment will still focus on recording data. We will make another optimization based on the test flight data."
"After the second test flight, we should start testing extreme operations..."
Chen Nian nodded and thought to himself:
It doesn’t really matter whether you try it or not, because with this level of power optimization, it’s only a matter of time before the leaves are floating.
And now...as long as we can land, it's done!
...
As if seeing through his pretended calmness, but actually nervous inside, the Jian-10 in the air completed all the items of the first test flight at an extremely fast speed, and then made an almost impeccable movement. , landed on the ground again.
The entire test flight ground was filled with joy.
"It's done! It's done!"
"Damn it, just say that our engine is not bad, what about the AL-31FN, it will never happen again!"
"It's so powerful...Ba Ye's successor is finally here!"
"The 606 institute is really good. In such a short time, the results are so good!"
"Nonsense, all the main structures of our engines have been verified, and most of the tolerance ranges are less than one ten thousandth. If the effect is not good, there will be trouble..."
Chen Nian stood aside and listened to the researchers' lively conversation with a smile. He looked at the J-10 with the cockpit cover slowly opening, and a thought came to his mind:
It won't be long before the name of this fighter plane will become known to everyone...
