The military-industrial scientific research system of the academic master.

Due to the lack of experience in organizing such a large-scale exhibition, the exhibition organizers did not arrange any explainers in the huge venue. They relied entirely on the paper materials produced by the exhibitors and the knowledge reserves of the visitors themselves.

But military fans are not the only ones who come to the air show.

Some are organized collectively by work units, others live nearby and come to join in the fun, and there are also reporters like Lao Liu who need to travel to collect materials for work, etc.

If these people don't explain it, they can basically just watch the fun.

Therefore, the crowd around Xi Boyang became more and more dense, and even quickly formed a quite obvious gathering area.

However, the main purpose of his trip was still photography, and the engine noise when the plane took off made it difficult to hear other things.

So after the J-8C completed the circling action just now, Xi Boyang raised the camera again and rotated the zoom ring on the lens at the same time.

In the era of film cameras, photographers could not check the shooting results in real time, but based on past experience, he knew that he should have obtained several good panoramic photos, and the next step was to capture some details.

This time, the No. 04 prototype was obviously accelerating as it flew over.

It is not often that you have your head shaved by a fighter jet flying at a height of less than 8 meters. Therefore, the J-C, which rushed towards the venue like a tiger descending from a mountain, gave the audience a great sense of oppression.

Many people even held their breath subconsciously.

However, experienced people like Xi Boyang know that it is impossible for the performance plane to really fly over the convention and exhibition center.

The crowd here is too dense, and if an accident occurs, the consequences will be immeasurable.

I just don’t know how this plane will change its flight path?

His right index finger rested lightly on the shutter.

As if to answer the question in Xi Boyang's mind, Prototype No. 04 suddenly made a lever movement. The attitude of the entire aircraft changed from horizontal flight to vertical upward almost instantly. At the same time, the roar of the two engines became more and more deafening.

People can even see the high-temperature gas behind the aircraft's tail nozzle, as well as circles of dazzling Mach rings.

"Are you going to make...a cobra?"

When the attitude of the aircraft changed, many people immediately thought of this super maneuver named by Pugachev.

But as a second-generation aircraft, this seems a bit outrageous.

"No, it's not super maneuvering, it's a single-plane climb at a high elevation angle! And the plane is still accelerating!"

Xi Boyang's voice was completely drowned out by the roar of the engine and the cheers around him.

But the plane was still accelerating as it flew vertically upward, which everyone could see.

Not everyone understands what this means -

In fact, before this, the Chinese Air Force had not equipped an aircraft with an actual thrust-to-weight ratio exceeding 1.

The specially improved J-6 air plane can have a thrust-to-weight ratio close to 1 on paper, but in order for an aircraft to fly into the sky, it must be equipped with a pilot and aviation fuel, so the actual thrust-to-weight ratio is lower.

The first mass-produced fighter capable of accelerating in vertical climb should be the F15.

The single-seat models of the subsequent F16, MiG-29 and Su-27 can also do this.

As a "quasi" third-generation fighter jet, the Mirage 2000 is not good at power. The Harrier fighter's vertical takeoff and landing relies on ground reflection airflow. The thrust-to-weight ratio in flight has not exceeded 1

Therefore, behind those four third-generation aircraft... it seems to be this J-4C.

However, even if you don’t know the twists and turns, it doesn’t matter. This large-angle climb followed by a 360° rotation on a vertical plane is visually shocking enough, and it is actually an important part of the era of machine gun combat. tactics.

If he did not have absolute confidence in the performance of the aircraft, the pilot would not complete such a maneuver at low altitude.

"Here I go, the climb rate of this plane just now... was a bit exaggerated."

The person who was the first to recognize Zi Boyang's identity just now held a telescope in his hand and couldn't help but sigh.

The other person next to me seems to know better.

"Not only the climb rate, but also the wing surface response of this aircraft is very agile. It is completely different from the J-7 and J-8 I have seen before."

"There is also the engine. From the beginning of the performance to now, even just through the sound, you can hear that the aircraft's engine thrust has been changing. Such frequent changes in the throttle valve position indicate that the reliability of the power is very high."

"Then the person who first said there was a second-class accident at Hojing was all lying?"

"Probably, otherwise it has only been three months from August to now. It would be difficult to even complete the fault analysis, let alone improve the engine..."

"..."

While these two people were discussing each other, Xi Boyang had already used up his first roll of film.

While he opened the film compartment as quickly as possible, took out a new film from his bag and put it in, he recalled the details he had just seen through the lens.

After he changed the film, he immediately adjusted the optical zoom magnification in a targeted manner, focusing on a few parts that he had not seen clearly just now.

"really……"

"The wing of this aircraft is different from the old J-8B! It uses leading edge slats!"

"The engine...the engine doesn't see much change, but the part connecting the fuselage and the tail nozzle is also different from before."

During the gap between the two performances, Xi Boyang's voice was transmitted to the ears of the people around him.

"This aircraft... is very different from the previous J-8B, and it has nothing to do with Grumman!"

"This is... completely our own, a new plane!"

……

When Xi Boyang finally calmed down, he realized that the film he had planned to use for this day had been taken in just ten minutes.

And just when he lowered his head and regretted his impulsiveness just now, and was thinking about whether to break through the crowd and go back to the hotel room to get new film, there was some commotion in the direction of the air show center near the airport.

Due to the dark crowd, Xi Boyang couldn't see clearly what was happening over there for a while.

But the cheers from the crowd soon gave the answer.

The J-8C just landed on the runway of Xiangzhou Airport after the flight show!

Xi Boyang suddenly remembered that he had just seen a somewhat unexpected open space in the exhibition area of ​​China Aviation Industry.

Obviously, this was arranged long ago.

Just as he speculated, soon, a trailer towed the No. 04 prototype that had just landed away from the end of the runway.

The on-site security personnel pulled up two human walls to allow the tractor and the aircraft to pass through the middle, and finally stopped at the empty space.

Two staff members wearing the uniforms of China Aerospace Technology Company appeared immediately and tore open the stuck part of the sign in front.

Xi Boyang, who had already taken a good position, was the first to see the big words written on the first line of the display board——

J-8C fighter jet and the turbojet 14 engine it uses.

"Ok?"

This way of writing obviously means that the exhibit is not just one aircraft.

He raised his head again and noticed something tightly wrapped next to him.

The two people just walked over and lifted off the rainproof cloth on the surface.

An aero engine was presented in front of everyone.

"Fuck-"
