Northwest. A certain military base!
Early the next morning, all the experts and professors who participated in the test arrived at the test site early, including Zhou Yang, Nie Nansun and others.
According to the test plan agreed upon at yesterday's meeting, they will not only observe the entire test of "Air Police No. 1" today, but also board the plane in groups.
Therefore, everyone is looking forward to today's test.
After all, this is the first early warning aircraft studied in China. Everyone wants to see how its performance is and whether it can fill this gap in the domestic field of early warning aircraft.
As soon as they arrived at the military airport, everyone saw a huge fighter plane parked on the airport runway.
After seeing this fighter plane, everyone couldn't help but exclaimed: It's so big and beautiful!
I saw that this fighter plane was more than 30 meters long, with a wingspan of more than 40 meters. The paint was also new, and it looked particularly beautiful.
The IL-14m and later Y-5 that everyone saw yesterday are just little brothers in front of this aircraft.
Nie Nansun whispered in Zhou Yang's ear: "This Tu-4 bomber fighter, our early warning aircraft is modified from this fighter. If you don't understand anything, you can ask me!"
Zhou Yang nodded but said nothing. Although he had not been exposed to the early warning aircraft project before coming here in this life, Zhou Yang had participated in the research and development project of the Air Police 2000 early warning aircraft in his previous life.
Although he is only responsible for the radar part above, during the research process, it is inevitable to learn from the failure of "Air Police No. 1" and sort out the reasons for its failure.
Therefore, Zhou Yang basically knew what Nie Nansun knew, but he may not know what Nie Nansun knew.
Because of this, when Zhou Yang saw the modified fighter plane in front of him, he didn't have much extra emotion except for being a little friendly.
Soon, Yang Xi, the head of the Sixth Institute, the R&D and design unit of Air Police One, and a group of technical backbones also arrived.
Today's test was very important, so after arriving at the scene, Yang Xi did not have too many greetings with everyone, but directly asked people to inspect the test aircraft that was about to take off.
Half an hour later, engineers and ground staff reported one after another that everything on the plane was normal.
Then the three crew test pilots and the experts invited to participate in the test took their positions and asked for instructions to take off.
Since the first thing to test was the stability of the aircraft, and Zhou Yang and others participated in the test of the radar function, they did not take off immediately.
With all personnel in place, Yang Xi agreed to take off the plane.
"Buzz..."
Following the tower's command, the test pilot of "Air Police No. 1" on the runway started the engine, the aircraft accelerated on the runway, and then soared into the sky.
The moment the plane flew into the sky, the audience burst into warm applause!
At this time, all aircraft R&D personnel on site, including Yang Xi, were very nervous. In previous tests, they found that the aircraft often deviated during takeoff. The pilot tried his best to control the aircraft, causing it to twist along the center line of the runway. Roll off and land the same way.
There is also a tendency to yaw and roll during flight after takeoff. The pilot must always exert force on the rudder during several hours of flight.
After later testing, they found that it was caused by the yaw moment caused by the propeller sidewash hitting the vertical tail after the engine power was increased.
In addition, there is a very serious problem. Because the radome located in front of the vertical tail is thick and has blunt edges, the airflow behind the dome separates during flight, causing turbulence, which acts on the vertical tail to produce vibration.
Vibration not only easily fatigues aircrew but also fatigues structures.
Beginning in September 1972, the design team began to eliminate vibration. After repeated trials, these difficulties were finally overcome.
Although they have conducted countless experiments and tests on the performance of the fighter aircraft before, no one knows whether the aircraft will fall apart at the critical moment.
While everyone was waiting nervously on the ground, the test pilot's voice came from the tower's loudspeaker: "Tower... Tower, flying altitude 8000, speed 580, the aircraft has no yaw or tremor, everything is normal... ."
After hearing the crew's report, all the scientific researchers in the 703 Institute stood up excitedly and clapped wildly. The atmosphere at the scene was very enthusiastic.
However, Zhou Yang on the side had a calm expression, neither applauding nor fanaticism in his eyes, which was a bit out of tune with the excited people around him!
He knew very well that the smooth operation of the aircraft was only the most basic function of the early warning aircraft. If it kept shaking, how would the staff above operate the radar system? Isn't this nonsense!
Therefore, the fact that the plane took off smoothly and operated smoothly does not mean anything, nor does it mean that "Air Police No. 1" is a success.
In fact, no one knows the ending of "Air Police No. 1" better than Zhou Yang now!
This fighter jet took ten years to develop and ultimately ended in failure, so the current cheers are meaningless.
Nie Nansun on the side saw Zhou Yang's demeanor and expression, and immediately patted him on the shoulder and said: "Everyone applauded, why didn't you react?"
Zhou Yang shook his head and said, "Why are you applauding? Just because the pilot said the plane is operating normally. Is it necessary?"
"There's none?"
"It makes no sense to me!"
Hearing Zhou Yang's unkind words, not only Nie Nansun was a little confused, but an old man with white hair and beard beside him also looked at Zhou Yang in surprise.
"Old Nie, who is this little comrade?"
Nie Nansun said hurriedly: "Mr. Huang, let me introduce to you. This is Zhou Yang, a genius in our radar field!"
Mr. Huang immediately extended his hand to Zhou Yang and said: "Hello, young man, I am Huang Yaolou, the chief designer of Air Police No. 1!"
After hearing the old man's self-introduction, Zhou Yang felt extremely embarrassed and felt as if he had been caught for saying bad things.
"Mr. Huang, I'm really sorry, I just..."
Before Zhou Yang could finish speaking, Huang Yaolou interrupted him and said, "We took the trouble to invite you guys here just to let you criticize us. As long as what we say is reasonable, don't be embarrassed! "
"And I also agree with what Comrade Zhou Yang just said. Just a smooth flight is really not worth being so excited. After all, what we are testing is an early warning aircraft. It should be a smooth flight without mechanical failures!"
Nie Nansun smiled and said, "You are still ambitious!"
"It doesn't matter if you don't have a big heart or not, let's just talk about it!"
Then Mr. Huang looked at Zhou Yang again and said, "Comrade Zhou Yang, you seem to have some research on aircraft. What do you think of our early warning aircraft?"
These words stopped Zhou Yang from asking, tell the truth, it's not appropriate.
It's too easy to offend people. He's not that naive. If someone asks you to give an opinion, you'll criticize them completely. Even if what you say makes sense, people will feel very uncomfortable.
What's more, what he is facing now is a large-scale military equipment that has been developed for seven or eight years. It is unknown how many people's efforts have been condensed. If Zhou Yang really wants to say what he really thinks in his heart, Zhou Yang is afraid that these people will come up and beat him.
But if Zhou Yang was asked to tell lies against his heart and brag about how advanced this fighter plane was, he couldn't say it out loud.
After all, "Air Police No. 1" was all flaws in his eyes, and he really couldn't bring himself to praise it!
For a while, Zhou Yang opened his mouth several times, but in the end not a word came out!
(Air Police No. 1: After the mission failed, the aircraft was changed back to a bomber, and later became an exhibit in the exhibition hall!)
