Mid June.

At noon, the sun hangs in the middle of the head, sprinkling golden and warm sunshine.

The Grain Grain Season has passed, and it is already very hot in most parts of the south, and it is entering the scorching heat.

However, Kat Station, which is located in the Hengduan Mountains, does not feel like entering summer, and the maximum temperature during the day has remained at around 22 degrees.

The two J-10a and two J-11a just finished their training this morning, slowly lowered their flight altitude, and faced the only two runways at the airport, and landed and taxied smoothly one after another.

"It's finally over."

In the tower, Yang Luo stretched, put down the phone, signed the flight log, and said to the deputy commander on the right: "Staff Officer Zhou, I'll have dinner first."

Staff Zhou said: "Captain Yang, you go first. I have to wait a little longer. There is still a plane that has not landed yet."

"Didn't it all land?" Yang Luo, who was about to get up and leave, asked in confusion.

"I came from another station." Staff Zhou replied.

Although Yang Luo is the highest commander of the tower, he rarely takes care of the tower and does not have a fixed time to command the tower. For example, today, he flew up and arrived at the tower commander, and Staff Zhou also changed from a commander to a deputy commander. Therefore, Staff Zhou did not report to him, and who knew when he left.

"Where did you come from? The Gannan Farm Station of your division headquarters?" Yang Luo asked.

"No, I don't know the specific station. I only received the notice this morning." Staff Zhou shook his head and said, "But it should have something to do with you."

"What do you mean?" Yang Luo asked.

Staff Zhou opened the flight log and said: "The aircraft model is also J-10c, and the call sign is 302."

Yang Luo is very familiar with the call of 302. Isn’t this Ye Jianlong’s call of 302?

Generally speaking, fighter jets of the same model will not have repeated call signs in the entire aviation unit, and one call sign corresponds to a fighter jet.

Only different models can have the same call sign, but it can be distinguished.

For example, Yang Luo's 301 is actually for the convenience of title. After reduction, his specific call sign is c10301. The c10 above actually points out that the model is J-10c.

During normal flight transfers, the landing station will be notified and there will be some simple information about the landing plane, including specific call signs.

"It does matter. He is my captain." Yang Luo nodded and asked, "How long will it take?"

Staff Zhou looked at the electronic clock hanging on the tower and said, "There are twelve minutes left."

"Okay, I'll leave later." Yang Luo said, took the flight log, found the page of Ye Jianlong's landing information, and signed his name.

Whoever commands, whoever signs.

More than ten minutes later, Ye Jianlong's voice sounded at the tower: "Call the tower of the Kat Station, c10302 requested to enter the site and land, it was finished."

Ye Jianlong used specific call signs, but did not use the reduced call sign and model.

This is due to personal habits and there are no specific regulations.

Yang Luo likes to use the reduced call sign and then report the model he drove.

"The tower received, there was no continuous wind direction, the wind speed was 0.5 meters in seconds, and the field pressure could drop."

Yang Luo pressed the call button and said, "Captain Ye, long time no see."

"302 received, uh, Yang Luo, why are you in commanding the tower?" Ye Jianlong said hesitantly.

"Why can't it be me? I have the final say in the Cat Station. I will be wherever I want." Yang Luo said bluntly, "You land first, I'll come down to find you right away."

"Hey, wait, have you left me lunch? I'm still hungry."

Ye Jianlong was indeed hungry, after all, he had been flying for more than four hours.

"I haven't eaten yet, let's wait together." Yang Luo said with a smile.

The roar of the engine in the sky became louder and louder. A J-10c fighter jet quickly became larger and appeared in the eyes of everyone on the tower. After flying four turns above the station according to the standard landing procedure, landing lightly on the runway.

After Ye Jianlong landed smoothly on the runway and ran away, Yang Luo threw down the telephone and left quickly.

When Yang Luo arrived at the hangar, Ye Jianlong had already rushed down from the cockpit and was chatting with Gou Quan.

"Captain Ye, you are welcome to guide the work." Yang Luo laughed and walked forward.

"Tell me, don't let me down." Ye Jianlong rolled his eyes and said.

“…”

After a glance, Yang Luo suddenly discovered that the aircraft engine was obviously different, as if it had been replaced.

"Captain Ye, why did your car change to the aircraft?" Yang Luo asked, walking towards the tail of the aircraft.

What Yang Luo saw was an engine with a jagged stealth design. This is the biggest difference from the previous al-31fn.

"Is this good?" Yang Luo asked in doubt.

The design took into account the service life of the al-31fn and the problem of being choked. Therefore, the Taihang engine and the al-31fn engine are interchangeable.

"Taihang-10c, three-element vector advance version." Ye Jianlong said with a smile.

"I'll go, the Liming Aircraft has finally risen. Taihang can finally be used on a single-engine fighter." Yang Luo sighed.

Liming Aircraft has been bumpy for decades, and even in the more than ten years since the Taihang engine was finalized, there are still many problems. They only dare to equip it on twin-engine fighter jets, but not on single-engine J-10.

I still remember that when I was in the test flight institute, the J-10d prototype was equipped with the Taihang engine, but there was a problem with the engine at that time.

Unexpectedly, after half a year, Liming Aerospace Engineering Company solved the problem and passed the final review and could actually be used on the single-engine J-10.

"How about the Taihang 1fn of the three-element vector?" Yang Luo asked.

Vector engine refers to installing a flow diversion system on the engine tail nozzle to change the injection direction of high-temperature and high-pressure gas, and then change the thrust state of the entire machine to complete a series of maneuvers.

Vector jet systems are divided into two types: binary and ternary. The engine tail nozzle with binary vector can only swing up and down, and high-temperature and high-pressure gas can only change the up and down direction; the engine tail nozzle with ternary vector can swing all directions, and high-temperature and high-pressure gas can also change the direction in all directions.

Triple vector engines are more advanced and more complex than binary vectors.

Now equipped in the J-1fn is a binary vector engine.

"The thrust is greater, the maneuverability is stronger, the acceleration performance is similar, and the ground start time is similar. Generally speaking, it is better than the Russians." Ye Jianlong thought for a while and replied.

"Good thing, is it that you only have to change one, or do you have to change it?" Yang Luo asked, wanting to touch the Taihang-10c and try the difference in the feel.

"We all need to change. Our two squadrons have been replaced, and only you will be the first squadron left. Four squadrons will be transported here in the sky, and there will be engineers from the Liming Aviation Engineer." Ye Jianlong said, "One of the things I came here is this."

After hearing Ye Jianlong's words, Gou Quan, who was following aside, instantly turned into a bitter face.

Changing aircraft engines is a major project. It does not count as the test flight time, but it takes at least one week. If the test flight debugging time is added, it is not surprising that half a month or a month is not surprising.

Although there are engineers from Liming Aviation Engine, you don’t have to think about it. The engineers only play a guiding role and will not do anything easily. The real thing is the maneuver team led by Gou Quan. This is the responsibility of the maneuver.
