The 037 J-7eggh has two airspeed tubes. The first is the tube more than 60 cm long at the nose. The second is a tube with winglets on the right side of the fuselage with small wings like door handles.
, the second one is the problem.
When everyone gathered around and looked at what Peng Chubin pointed out, they suddenly found some traces of rust in the hole of the tube. In chemical terms, there was oxidation inside.
Peng Chubin's face turned blue and white, and he said, "How come it rust? It was fine when the comprehensive inspection was conducted yesterday."
Li Zhan carefully checked and said, "It's not the responsibility of the machinery, it's due to the environment. The temperature difference between morning and evening is large and the moisture is sufficient, and the southeastern sea breeze is blown. There is no anti-corrosion treatment in the hole, so it is not surprising that rapid oxidation is formed."
Through the visitor, everyone saw that the rusting area was not large. It was very likely that the moisture entered the hole and then a small amount of condensation residue appeared. Overnight, oxidation occurred, that is, rusting. The rusting place was not
Leveling affects the state of air entering, which then causes the airspeed meter to fail and cause large errors.
The solution is very simple: remove rust and anti-corrosion treatment.
Li Zhan said to Peng Chubin, "Captain Peng, the temperature difference in winter is large, and it is on the beach again. I suggest adding an anti-corrosion rust inspection to the takeoff inspection project."
According to regulations, such detailed inspections will be carried out after several hours of flight, so it is not their responsibility to not find the second airspeed tube rust on the aircraft.
Even so, Peng Chubin was still ashamed and said, "Team leader, I will conduct a thorough review and will definitely improve it. I will check everything before taking off in the future."
"You don't have to blame yourself for your fault, and there is no need to review it. You are not wrong in following the procedures completely." Li Zhan said with a smile, "Treat the specific situation in detail. If you find a problem, we can come up with the corresponding solutions.
”
"Please rest assured that the team leader, I promise to complete the task without any discount and ensure that the plane is good." Peng Chubin stood attentively.
Li Zhan patted his shoulder, "Hurry up and deal with it, I'm waiting to continue training."
"Yes!" Peng Chubin immediately started working with his people.
Several pilots walked aside, and Zhang Xueyang frowned and said, "There is no similar problem with J-15."
Li Zhan said, "Dongsanguai is a test machine. Cheng Fei has never been exposed to similar situations. It is normal for some design data to have errors. Exposing the problem through actual use is also one of the tasks of the test machine."
Cao Fufei touched the buzz cutter on the touchpad and said, "I didn't expect that I could just say it casually."
After looking at the sky outside the hangar, Li Zhan said, "This location is too special. If you get on the ship in the future, it is estimated that the aircraft's anti-corrosion and rust is a very important maintenance work."
Tang Leilei pulled up his collar and sniffed it, saying, "Yes, yes, let alone the planes after a long time, I feel like people are going to rust, and there is a smell of salted fish."
Everyone smiled, Li Zhan looked back at the busy crew and said, "The problem will be solved soon, I have to continue flying. You should wait in the flight briefing room as planned, and wait for me to finish a flight order.
Cao went on, Tang Leilei went on the last one."
"Yes!" Cao Fufei and Tang Leilei stood up with their chests.
Zhang Xueyang cannot fly the No. 037 J-7eggh, he does not have the qualification to fly for this model. Cao Fufei's original Hongqi Division was one of the most experienced troops using the J-7 series fighter jets, from the earliest model to the latest G model
They have been able to use the J-7 series for decades, and are also one of the few troops equipped with the J-7 fighter jets at that time. To this day, the Hongqi Division still has a large number of J-7e, J-7g fighter jets and even old J-
7 Type 2 is in the list.
Therefore, Cao Fufei's familiarity with the J-7 series of fighter jets can be said to be more familiar than Li Zhan. The most important thing is that when the Hongqi Division modified the J-10, he was the leader of the team to modify it, so he was the leader of the J-10, so he was the J-10.
The 10 is also very familiar, but he modified the J-11a after passing the pre-selected training of Feisha. Yes, the pre-selected modification uses the J-11a to replace the J-15—the J-15 has not had many J-15s at all.
From the original imported batch of Su-27sks to the domestic J-11 series fighter jets, it is said that they try not to equip troops in the Northeast area as much as possible. It is said that when the technology is introduced and produced by itself, there are relevant terms in the agreement...
From this point of view, Cao Fufei's advantages are very obvious. The No. 037 J-7eggh uses the Flight Control System of the J-10, and the Flight Control System of the Flight Control System originates from the J-10, so Cao Fufei drives the No. 037 J-7eggh completely.
No pressure.
Li Zhan has high hopes for Cao Fufei. The gap between Tang Leilei and Cao Fufei lies in his experience. The former is the same group as Li Zhan, and now he can have thousands of flying hours. He is completely following Li Zhan in Beiku Eagle Falcon.
.
Peng Chubin's crew was very fast. After dealing with the rust problem, they conducted a comprehensive and rapid maintenance on the plane. An hour and a half later, Li Zhan once again accepted the plane and continued to fly the plane.
On the last trip, the sky was already half dark. The ground in the west was dark but the sky was red. The ground in the east was still a little bright, but the sky had begun to block it.
Li Zhan in the cockpit had no feeling, but the ground personnel had completely changed their appearance. Looking at the tower, the No. 037 J-7eggh light carrier-based test aircraft took off and climbed with a large side sliding angle.
When turning rapidly, the machine head is adjusted from north to west.
What we need to do next is a long-lasting dark cabin flight training, simulating a carrier-based fighter taking off from the aircraft carrier deck and heading to the airspace 200 kilometers away to perform a mission, and then completing the established mission in five minutes and returning to the mothership. Through this process
To exercise the pilot's take-off and landing ability.
There is a key difficulty here - finding the "mother ship".
So Li Zhan first needs to find a fertile ground training base.
Li Zhan in the dark cabin state could not visually discover the "mothership", and in the sea and air, it was difficult for pilots to find aircraft carriers from the vast ocean - for humans, aircraft carriers are a behemoth, and for the ocean, aircraft carriers are even a drop in the ocean.
Not counting.
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 commanders on the ship.
What Li Zhan has to do now is this attempt, which is also a training node with great significance in dark cabin landing training.
He drove the No. 037 J-7eggh to the inland direction for a hundred kilometers, then continued to turn left slowly, and drew a large counterclockwise turn circle to fly southward to the sea. Then he continued to turn left according to the instructions of the ground tower.
Level flight was resumed at 120 kilometers above the southeast sea of the fertile soil flying training base, and finally returned to the base from here and began to look for the "mother ship".
It was probably a semicircle from the south to the southeast of the base, with a voyage of 400 kilometers.
As a result, when he arrived at a distance of 120 kilometers above the southeastern sea, Li Zhan was completely in a dark cabin.
