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

After a physical examination confirmed that there were no physical problems, Chang Haonan, wearing a flight suit and a flight helmet, carefully climbed into the front cockpit of the J-7 aircraft with the help of ground crew members early the next morning.

As a training aircraft, the rear cabin of the JJ-7 has a higher level of flight control authority.

And sitting there was the most experienced flight instructor in the army, named Zhang Jiujiang.

A few dozen meters away from the J-7, a fighter jet with a slender body was also ready to fly.

It is the No. 8 prototype of the J-3-03, and it is also the first of the two full-state verification aircraft in the original plan.

To be honest, this is the first time Chang Haonan has seen the J-8 fighter jet with his own eyes.

Although it is not comparable to the J-10, J-16, J-20 and other advanced models he had seen before his rebirth, in this era, especially when it is parked near the J-6 or J-7, the visual effect is outstanding.

It’s no wonder that he got the title of “Cai Guoqing in the Sky”.

According to Chang Haonan's calculation conditions, the No. 03 prototype had two Aspaid air-to-air missiles hung under each of its left and right wings.

However, they are all models that have restored their weight and size.

After all, there are less than 80 missiles purchased from Italy in total. Each time they take off, their lifespan will be consumed even if they are not launched. Naturally, it is impossible to even out 5% of the number for test flights at one time.

Chang Haonan put on the oxygen mask according to the training before boarding the plane, took a deep breath, and closed the canopy to the left.

The sound of the howling wind outside and the sound of the power supply truck and the air source truck working suddenly became much quieter.

As a light aircraft, the cockpit of the J-7 was much smaller than he had imagined, so much so that just sitting in it felt cramped.

"Engineer Chang, after takeoff, you must be careful not to step on the rudder with your feet, and don't touch anything on the aircraft panel."

Zhang Jiujiang was in the back seat while doing the final inspection before the flight and said:

"After takeoff, I will try my best to ensure that the plane is as stable as possible, but after all, this is a small plane. It will still be bumpy if it encounters airflow. If you feel uncomfortable in any way, you must tell me immediately."

"No problem." Chang Haonan gestured backward to indicate that he understood.

As soon as he finished speaking, the No. 03 prototype next to him had released its brakes and started to slide slowly, and quickly passed in front of Chang Haonan.

Compared with the J-7 he was riding on, the J-8-3 was indeed a very huge aircraft.

"This new aircraft of yours should be equipped with troops soon, right?" Zhang Jiujiang suddenly asked Chang Haonan, looking at the back of the No. 03 verification aircraft slowly going away.

The latter thought for a while and felt that he should be able to solve all the pitfalls encountered in the August 3rd Project.

In fact, in the original timeline, if the unlucky No. 04 prototype had not been damaged due to completely non-technical reasons, even if the reliability of WP14 was not optimistic, the J-8-3 might have finally been finalized in a technical state similar to the J-8F service.

"Probably, the current progress is pretty good."

"That's great. We now dream of more advanced fighters."

After hearing Chang Haonan's answer, Zhang Jiujiang's tone became significantly lighter:

"It's a pity that the number of J-8B and Su-27 is too small now."

For those within the aviation industry system and the Air Force, these are certainly no secrets.

"Can the J-8B still be considered an advanced fighter?" Chang Haonan said with a dumb smile.

"Alas, you don't know how much those of us who fly J-6 and J-7 envy those J-8 troops." Zhang Jiujiang said and also put on the oxygen mask on his face: "At least they can fly one or two every time For an hour, for us, sometimes if we make a big move, we have to return in half an hour."

Chang Haonan wanted to tell the other party that there should be a large number of heavy fighter jets in service in a few years, but it was obviously not appropriate to say such words now, so the atmosphere in the cabin fell silent for a while.

Fortunately, the No. 03 prototype in front had already taken off at this time, and the tower informed Zhang Jiujiang that it was ready to enter the runway.

As several surrounding auxiliary vehicles evacuated one after another, Zhang Jiujiang slowly pushed the throttle valve to keep the engine speed at about half, and then released the brakes.

Chang Haonan, who was in the front seat, only heard the roar of the turbojet engine gradually increasing, and then the plane began to slide amidst a sudden push on the back.

Although he had flown a lot in his previous life, this was the first time he had such a broad view.

There is still some freshness.

But soon, as the plane began to speed up and prepare to take off, Chang Haonan felt as if there was a huge force pressing his whole body on the back of the seat, making it difficult for him to even breathe.

The J-7 took off at a very high speed, so the taxiing phase lasted for a relatively long time.

But after all, it is just a light aircraft, and it was still very light when it finally lifted off the ground and took off.

"Engineer Chang, how are you feeling? Do you have any symptoms such as dizziness or stomachache?"

Zhang Jiujiang looked at Chang Haonan in front of him who had remained motionless and asked with some worry.

"It's okay, I feel good. It's just the first time to go to the sky from this angle. It feels a bit...new."

Soon, the J-7 broke through the speed of sound at an altitude of meters. The vibration at high subsonic speeds disappeared instantly, and the aircraft became stable.

"Pay attention to the rearview mirror, the prototype is slightly lower than us." Zhang Jiujiang reminded.

Chang Haonan raised the camera hanging on his body and pointed it to the right, always ready to press the shutter.

Zhang Jiujiang is worthy of being one of the best flight instructors in the army, and he is extremely skilled in controlling speed and position.

Under his control, the relative speed between the two aircraft was only about 10 kilometers per hour. The J-7 even performed a smooth and slow barrel roll maneuver, providing Chang Haonan with an excellent shooting opportunity.

……

Half an hour later, the two planes landed smoothly. Chang Hao went down to the ground and handed the camera in his hand to Yang Fenghata, who was already waiting next to the tarmac.

The photos were quickly imported into the nearby computer, ready to be compared with Chang Haonan's calculation results.

"Why don't you come and witness it with your own eyes?" Yang Fenghao looked at Chang Haonan who was leaning next to the boarding ladder with a calm expression.

After hearing this, Chang Haonan showed a confident smile:

"No need, I already knew the result when I saw the No. 03 prototype in the sky."

He waited until the other party turned around, then quickly reached out and rubbed the back of his thighs that were a little weak——

I didn't feel it when I was on the plane. Just now when I landed on the ground, my legs were a little weak, and I almost made a fool of myself in public by not being able to stand.

After all, it was a bit too exciting to experience supersonic flight in a fighter jet for the first time.

And just when Chang Haonan finally managed to regain control of his legs and was about to try to stand up straight, a burst of cheers suddenly broke out from the crowd surrounding the computer not far away.

"That's right! It's completely right!"

Chang Haonan's simulation analysis results are almost completely consistent with the real flow field distribution shown by the thin red wool lines in the photo!
