No. 037 J-7EGGH has two airspeed tubes, the first is the tube more than 60 centimeters long in the nose position, the second is a tube deployed on the right side of the fuselage with winglets like a door handle, and the second one is the second one.

When everyone gathered around and looked at Peng Chubin's point, they found that there were some traces of rust in the hole of the pipe, which in chemical terms means that there was oxidation in it.

Peng Chubin's face turned blue and white for a while, and said, "How can it be rusty, it was fine when I was fully inspected yesterday." ”

Li Zhan checked it carefully and said, "It's not the responsibility of the maintenance, it's the environment." The temperature difference between morning and evening is large and the water is sufficient, and it is the southeast sea breeze blowing, and there is no anti-corrosion treatment in the hole, so it is not surprising that the rapid oxidation phenomenon is formed. ”

Through the visitor, we saw that the area of rust was not large, and it was very likely that the moisture entered from the mouth and then a small amount of condensation remained, and there was oxidation overnight, that is, rust. The rusty place is uneven, which affects the state of air entry, and then causes the airspeed gauge to malfunction, and there is a large error.

The solution is very simple, remove rust and do anti-corrosion treatment.

Li Zhan said to Peng Chubin, "Captain Peng, the temperature difference here is large in winter, and it is on the seaside, so I suggest adding an anti-corrosion and rust inspection to the take-off inspection item." ”

According to the regulations, such a detailed inspection would not be carried out until several hours after the flight, so it was not their responsibility that the maintenance side did not find the problem of rust on the second airspeed tube.

Rao is like this, Peng Chubin is still ashamed, and said, "Team leader, I will review it deeply, and I will definitely improve it, and I will check all of them before taking off in the future." ”

"It's not your pot, you don't have to blame yourself, and you don't need to review, you are not wrong to follow the procedure completely." Li Zhan said with a smile, "Treat the specific situation on a case-by-case basis, and let's come up with corresponding solutions when we find problems." ”

"Please rest assured, team leader, I promise to complete the task without compromise and ensure that the plane will be in good condition." Peng Chubin stands on the right path.

Li Zhan patted him on the shoulder, "Hurry up, I'll wait to continue training." ”

"Yes!" Peng Chubin immediately took people to work.

Several pilots stepped aside, and Zhang Xueyang frowned and said, "There are no similar problems with the J-15. ”

Li Zhan said, "Dong San Gui is a testing machine, Cheng Fei has not been exposed to similar situations, and it is normal for some design data to have errors." Exposing problems through practical use is also one of the tasks of the testing machine. ”

Cao Fufei touched the head of the board and said, "I didn't expect me to say it casually, and it was really right." ”

Looking at the sky outside the hangar, Li Zhan said, "This location is too special, and it is estimated that the anti-corrosion and rust of the aircraft is a very important maintenance work when it is on the ship in the future." ”

Tang Leilei pulled up his collar and sniffed, saying, "Yes, yes, yes, don't talk about airplanes after a long time, I feel that people are going to rust, a smell of salted fish." ”

Everyone smiled, Li Zhan looked back at the busy maintenance team, and said, "The problem will be solved soon, I have to continue flying, you still wait in the flight briefing room as planned, and when I finish flying a sortie, Lao Cao will follow, and Tang Leilei will go last." ”

"Yes!" Cao Fufei and Tang Leilei straightened their chests.

Zhang Xueyang can't fly No. 037 J-7EGGH, and he is not qualified to fly this model. Cao Fufei's original Red Flag Division was one of the most experienced units in using the J-7 series fighters, from the earliest type one to the latest G type, they have been able to J-7 series for decades, and they were also one of the few units equipped with J-7 fighters at that time. To this day, the Red Flag Division still has a large number of J-7E, J-7G fighters and even the old J-7 II in the list.

Therefore, Cao Fufei's familiarity with the J-7 series of fighters can be said to be higher than that of Li Zhan. The most important thing is that when the Red Flag Division modified the J-10, he was the head of the regiment leading the modification, so he was also familiar with the J-10, but he was the J-11A that was modified after passing the pre-selection of the Flying Shark training, yes, the pre-selection modification replaced the J-15 with the J-11A - there are not many J-15 at all.

From the original imported batch of SU-27SK to the domestic J-11 series fighters, it is said that they try not to equip the troops in the northeast as much as possible......

Looking at Cao Fufei's advantages in this way, it is obvious that the 037 J-7EGGH uses the flight control system of the Thunder Dragon, and the flight control system of the Thunder Dragon is derived from the J-10, so Cao Fufei has no pressure at all to drive the 037 J-7EGGH.

Li Zhan has high hopes for Cao Fufei, and the gap between Tang Leilei and Cao Fufei lies in experience, the former and Li Zhan's troops in the same batch, and now they can have thousands of flight hours completely following Li Zhan in Beiku Eagle Falcon.

Peng Chubin's maintenance team moved quickly, and after dealing with the rust problem, they carried out a comprehensive and rapid overhaul of the aircraft, and an hour and a half later, Li Zhan once again took over the aircraft and continued to fly to the standard.

By the last trip, the sky was already in a state of semi-darkness, the ground in the west was dark but the sky was red, and the ground in the east was still a little bright but the sky had begun to darken.

Li Zhan in the cockpit didn't feel anything, but the perception of the ground personnel completely changed. Looking from the tower, the No. 037 J-7EGGH light carrier-based test aircraft took off and climbed neatly and completed a sharp turn with a large sideslip angle, and the nose of the aircraft was adjusted from facing north to west.

The next step is to conduct a relatively long-lasting dark cabin flight training, simulating a carrier-based fighter taking off from the deck of an aircraft carrier to the airspace 200 kilometers away to carry out a mission, and returning to the mothership after completing the scheduled task five minutes later, through such a process to exercise the pilot's take-off and landing ability.

There is a key difficulty in this - finding the "mothership".

Therefore, Li Zhan first had to find a fertile ground flight training base.

Li Zhan in the dark cabin state could not find the "mothership" by sight, and in the sea and air, it was difficult for pilots to find the aircraft carrier from the vast sea - the aircraft carrier is a behemoth to mankind, and the aircraft carrier is not even a drop in the ocean to the ocean.

Therefore, it is necessary to return according to the guidance of the ground/mother ship, and even in the case of poor visibility, the entire landing process must be carried out completely passively according to the instructions of the ship's command staff.

What Li Zhan is doing now is this attempt, and it is also a training node of great significance in the training of the dark cabin landing on the ship.

He drove the No. 037 J-7EGGH to the inland direction for 100 kilometers, then continued to slowly turn left and drew a large counterclockwise turning circle to fly south to the sea, and then continued to turn left according to the instructions of the ground tower, resumed level flight 120 kilometers above the sea surface southeast of the Fertile Soil Flight Training Base, and finally began to return to the base from here and began to look for the "mother ship".

It probably flew in a semicircle from the south to the southeast of the base, with a range of 400 kilometers.

As a result, when he reached a distance of 120 kilometers above the southeast sea, Li Zhan was completely in the dark cabin.
