Yang Luo (cāo) controlled the 301 J-10C to make a U-turn in front, braked steadily, and reported to the tower: "Report to the tower, the 301 systems are normal, the engine is working stably, request an air test flight, over." ”

"301, check again to be safe, over." Ye Jianlong was very cautious and gave the order to check again.

"301 understood, over." Yang Luo's tone was calm, without impatience.

Although it is very cumbersome, Yang Luo does not think that this is a superfluous move, it is very necessary.

Aviation is rigorous and loyal to the harsh.

Yang Luo once again inspected the various systems of the fighter, especially the power system, which was the most important of all the systems of the fighter.

Confirming that everything is normal, Yang Luo reported again: "Tower, confirm that all systems are normal, request an air test flight, over." ”

"301, can be tested in the air, the wind direction on the ground is ......"

This time, Ye Jianlong readily agreed to Yang Luo's request and gave meteorological parameters.

"301 received, ready to take off, will use afterburner to take off, over."

"Yes."

The throttle valve was in the end, the brakes were released, and the 301 J-10C once again accelerated and slid on the runway.

Turn on afterburner.

"Boom!"

As aviation fuel was injected into the afterburner, the roar of the Taihang-10C aero engine became more and more intense, deafening (yù) deafening, resounding around the station, the tail flame of the jagged tail nozzle spray (shè) changed from azure blue to orange red, and the high-temperature air flow swept the runway, raising a puff of fine dust.

In an instant, the 301 J-10C was like a disarmed shell, moving forward along the runway and going out.

"I'll go!"

Yang Luo was taken aback, he didn't have any mental preparation at all, he thought it would be like the AL-31FN aero engine, but he never expected that the thrust of the Taihang-10C aero engine would be so strong when the afterburner was turned on.

Yang Luo's feeling was that the fighter plane suddenly rushed forward, and his back was hit hard by the seat, and the feeling of pushing his back was very strong.

Previously, when the 301 was changed, Yang Luo flew over Ye Jianlong's 302 J-10C, perhaps because of the afterburner in the air, the present (shēn) has a high airspeed, so the feeling of pushing back is not so strong.

"How does it feel to drive afterburner? Surprised? Ye Jianlong asked with a smile, and his mind couldn't help but think of how he felt when he took off for the first time.

"Full of pushing back feeling, surging power, good thing!" Yang Luo was full of praise, "I want to send a hundred likes to Liminghang." ”

Soon, the 301 J-10C reached the critical speed of take-off, Yang Luo did not hesitate at all, decisively pulled the lever to raise his head, and the 301 J-10C jumped up gently, roaring off the ground, facing the blue sky.

Seeing the fighter plane leave the ground and enter the air, many people couldn't help but smile on their faces, especially the aircraft crew led by the engineers and Gou Quan of Dawn Aviation Engine.

"301, report on the condition of the body (qíng), done." Ye Jianlong held the military binoculars, looked at the 301 J-10C climbing to a high altitude, and said through the radio communication channel.

"The body (qíng) is in normal condition, the engine is normal, it feels very good, (cāo) is mellow and free, without the slightest jerkiness, it's over." Yang Luo replied excitedly.

"301, you can start the maneuver test flight, if you have any problems, report to the tower immediately, over." Ye Jianlong said.

"301 understood, over."

Yang Luo climbed at a rate of 200 meters per second, and when he climbed to 6,000 meters, he flattened, not that he couldn't go up, but that he didn't (yǔn) Xu.

The first test flight after the replacement of the aviation engine is generally carried out at medium and low altitudes, and will not go up to an altitude of more than 10,000 meters, mainly because of the fear of problems, such as engine shutdown and the like.

Only after the first test flight will the subsequent test flight reach an altitude of more than 10,000 meters.

After the replacement of the aviation engine, it is necessary to conduct at least three or more test flights to ensure the safety and stability of the engine.

After leveling in the air at 6,000 meters, Yang Luo directly came to a large-angle dive, and did not pull up until a height of one thousand meters, but it was not leveled, but climbed at a large elevation angle, almost making a low-leisurely maneuver.

"301, your movements are too rough, start with a simple maneuver, don't do a big overload maneuver at the beginning." Ye Jianlong reminded.

"301 understood." Yang Luo replied helplessly.

After climbing and pulling to a height of 2,000 meters, Yang Luo began to start with the most basic movements and gradually increase the difficulty.

Left and right turns, rolls, ......

Circling, sharp upward turns, horizontal figure 8s, catty buckets, half-roll reversals......

High yoyo maneuver, S maneuver, drum maneuver......

A wave in a wave!

One maneuver after another, Yang Luo seemed not to get tired, and flew up in the air.

After doing a large overload maneuver, Yang Luo changed the level of the fighter, kept it in level flight, rested for a while, and then turned on the afterburner and soared to supersonic speed.

After soaring to 1,800 kilometers per hour, Yang Luo withdrew from supersonic flight, returned to the subsonic range, and returned to the sky above the station.

"Tower, I'm going to test the stall maneuver, over." Yang Luo asked the tower for instructions.

"The tower received, it can be carried out, over."

Ye Jianlong has no reason to disagree, the test flight is to test in all directions.

"301 understood, over."

Yang Luo took a deep breath of on-board oxygen, his eyes were slightly solemn, he poked out his left hand and disconnected the angle of attack limiter.

Tie rod, nose elevation angle 110 degrees.

The 301 J-10C stood up like a cobra ready to attack.

Cobra maneuver.

Two seconds later, the nose was lowered, level flight resumed, and acceleration to about 500 kilometers.

The Cobra maneuver is one of the relatively simple of all the overstall maneuvers, and for Yang Luo, there are no problems and it can be completed easily.

Immediately afterwards, Yang Luo did stall maneuvers such as returning the horse pistol and falling leaves, but there were no problems, and it was completed smoothly.

Although Yang Luo has only been in the army for one year, and it has only been a little more than half a year since he modified the J-10C, no one in the whole army aviation has a thorough understanding of the stall maneuver.

The number of times Guy Yang Luo has played stall maneuvers is too much, and in the system space, Yang Luo has to fly all the stall maneuvers almost every day.

As the saying goes, what makes perfect, the more you fly, the more you understand.

This test flight, until the fuel alarm, Yang Luo landed, and the first test flight was over.

Perfect test flight without any problems.

Yang Luo was very satisfied with the Taihang-10C aero engine.

In the next two days, Yang Luo conducted two more test flights, and the Taihang-10C aero engine was very stable, without any moths, safe and reliable, and reached the service standard.

Yang Luo had a feeling that after changing to the Taihang-10C aero engine, the relationship between him and the 301 J-10C became more tacit, like water (rǔ)-blending, almost reaching the highest level of man-machine integration.
