There were no collisions, no accidents, and no sudden loss of power that everyone was most worried about. The J-6 fighter with the temporary wireless call sign 01 taxied safely to the end of the runway.
The scene suddenly erupted into excited cheers.
Jiang Xin said to Liu Daoming, "Old squad leader, it seems that the oil is suitable for turbojet VI. The fuel compatibility of this old jet engine is much better than imagined."
"When there was a shortage of aviation kerosene, the troops once used alcohol as a substitute. It was barely able to fly, but it did more damage to the engine. Secondly, there was a gap in thermal efficiency. It was a last resort." Liu Daoming recalled.
Jiang Xin's eyes followed the J-6 as it taxied to the end of the runway and said, "Judging from the test run, there is no problem with the power system, and there should be no problem with the control system. It is a foregone conclusion that this old aircraft will return to the sky."
."
"It's something worth remembering." Liu Daoming put his hands behind his back and smiled, looking at the J-6 as if he were looking at old friends who had been friends with each other for decades and had been together through thick and thin.
Jiang Xin smiled, "I never thought I would have the opportunity to participate in repairing the J-6. In fact, when I was in school, there was no content about the J-6 in the textbooks. The most basic content was the second-generation fighter, which is the J-7 fighter.
Eight of these series.”
"Times have changed. Today's aircraft are becoming more and more advanced. I can't keep up. I want to retire early. There is no use in the army anymore." Liu Daoming sighed.
Jiang Xin said, "Old squad leader, what you said is wrong. With your unique skills, even all the mechanics in the entire base combined cannot catch up with you."
This is correct.
There are only two or three people in the air force in the entire Northeast region who can handle the legendary problem of listening to sounds.
Liu Daoming is no longer on the front line. Firstly, he is getting older and secondly, he has to bring in new people, but his unique skills have never fallen behind.
Even when fraternal troops thousands of miles away encountered incurable diseases, or when Shen Huoyi's factory encountered problems, they would come over and ask him for consultation.
Li Hai drove the J-6 back and stopped at the original location.
Jiang Xin and others immediately rushed forward to check the condition of the plane.
After opening the canopy, Li Hai stood up from the cockpit and said happily, "The aircraft is in good condition and can be tested."
Liu Daoming said, "If there are no other problems, you can conduct a test flight. However, you must also conduct a ground test on the other aircraft first."
"Yes! Do it now!"
Li Hai then conducted a ground rolling test on the second J-6, and the situation was also very good. The "picky eating" situation that he was most worried about did not appear, which is the best result.
After a busy period of work, Li Hai stood next to the plane again, this time it was time to fly for testing.
The maintenance staff filled up the fuel of the J-6 with the radio call sign "Temporary 01", checked the condition of the aircraft again, and completed flight preparations.
The appearance of the temporary No. 01 J-6 is terrible, because it has not been painted, and the paint is mottled. The appearance of a car parked in the open air for more than ten years is what it looks like.
One of the more embarrassing aspects is that because it is an old aircraft, the radio on board has long since failed to meet current standards, so it is impossible to establish radio contact with the tower.
Li Hai's solution was for Li Hai to bring the individual radio station to communicate with the tower. The antenna on the plane was still usable, so Liu Daoming modified it and connected the transmitting device of the individual radio station to the antenna line on the aircraft.
, in this way, the communication range is expanded. On the left side of the instrument panel, something similar to a car mobile phone holder is added, and a personal radio, not much larger than a mobile phone, is placed on it.
In this way, Li Hai could contact the tower at any time with earplugs, but he could not use the "Midea" function - that is, he could not use the international general communication channel to make calls.
However, this is not important.
The communication problem has been solved, and now it’s time to watch Li Hai’s test flight.
Once the test flight is successful, he and Dang Weimin can fly the two J-6s for normal flight training.
On the tower, several leaders of the Red Flag Division were waiting with bated breath for the moment when the old J-6 took off successfully and witnessed this small historic moment.
Li Hai closed the canopy, gave a thumbs up, the signalman waved the flag, and Li Hai slowly stepped on the accelerator and slid off the apron.
There were no other flight missions at the base today. Basically, everyone who could come out came out to watch. They stood on the taxiway on the tarmac, eagerly anticipating this historic moment.
"Hey, come to the cave, you are ready to take off."
"Lindong understands."
Li Hai did not dare to take it lightly. After arriving at the take-off position, he still made a final check carefully to ensure that the three major systems were in normal operation.
Immediately, he called the tower, "Tower, the cave unit is ready, please take off."
"You can take off next to the cave."
Li Hai put the flaps in the take-off position, stepped on the brakes, then held the control stick with both hands and turned hard in circles, three turns left and three turns right, and continued to push the rudder hard with both feet. This was to check whether the various movable surfaces were normal.
, it is very important for flight control.
No problem anymore.
Li Hai pushed the accelerator to the maximum, and the two turbojet-6 engines roared. The unique harsh roar of the turbojet engine came one after another, which was obviously different from the sound of the turbofan engine.
After the speed reached the specified value, Li Hai suddenly released the brakes.
The temporary No. 01 J-6 suddenly jumped forward, as if the clutch was not controlled properly, and then started to accelerate and roll with a roar. The protective cover of the landing gear tire was particularly conspicuous, as if it was wearing winter boots.
Li Hai pulled the lever and raised his head, and the J-6 left the ground smoothly and climbed up with its head held high.
Everyone shook their fists excitedly.
As long as it successfully leaves the ground, the test flight is half successful!
"Coming to the cave, flying around the field, reporting the status of the aircraft at any time, over." Wu Guangwei has transferred to the tower to take command, and Lin Xiaotong will serve as his deputy commander.
Li Hai said, "I understand that the unit is flying around the field near the cave."
After climbing to an altitude of 500 meters, Li Hai slowly turned to the right, that is, turned clockwise, and made a circular flight with the base as the center.
The temporary No. 01 J-6 seems to have come from history and appeared in this prosperous era, as if it is examining what the younger generations have built up the country they old guys have built.
After three circular flights, Li Hai began to fly through the field. The first medium and low altitude was usually to fly along the runway towards the field at an altitude of 500 meters.
The officer of the base's propaganda department pressed the shutter hard to record the scene of the old man who was determined to be thousands of miles away. The young officers and soldiers looked at this scene with wide eyes, feeling like they were reborn and returned to the 1950s and 1960s.
Li Hai flew through the field for the second time, this time the flight height was only fifty meters.
This time everyone can see it more clearly. The J-6 is still young and its flying posture is very good.
The third flight through the field was at an altitude of 20 meters, basically flying close to the runway.
Wu Guangwei approved the third pass flight.
Lehi flew through the field for the third time.
The Provisional No. 01 J-6 roared past, and the sharp-eyed Dang Weimin noticed that something was not right at the engine nozzle.
He frowned and said, "Gong Jiang, the color of the tail flame at the nozzle seems to be wrong."
Jiang Xin quickly raised the telescope and looked over. After observing carefully for a while, she shook her head slightly and said, "It looks quite normal."
He said and handed over the telescope.
Dang Weimin took the telescope and followed the temporary No. 01 J-6 for observation, saying, "Maybe I saw it wrong, there seems to be no problem."
"Tower, I am the ground technical team. I want to ask the pilot about the power output of the aircraft." Jiang Xin called the tower and made a request.
"Tower received."
Deputy Commander Lin Xiaotong was responsible for contacting the ground technical team. He immediately asked Li Hai, "Next to the cave, how is the power output of the aircraft? Is it normal?"
Li Hai looked at the tachometer. The pointer was very stable, which meant that the power output was very stable. The absence of fluctuations meant that the engine was in good condition.
"The power is normal and the aircraft is in normal condition," Li Hai reported.
Shortly after Lin Xiaotong replied to Jiang Xin, Li Hai thought about it carefully and asked for instructions, "Tower, I want to do more low-altitude passes. The low-altitude flight of the aircraft seems a bit awkward."
"Lindong Yao can continue to fly through the field at low altitude, and pay attention to maintaining speed." Wu Guangwei readily agreed.
Test flight, test flight, naturally, if you feel something is wrong, you should try it.
"Lindong understands."
Li Hai turned a corner and changed from flying around the field clockwise to flying around the field counterclockwise, that is, changing from the original route from south to north to flying from north to south.
Sometimes you have to believe in evil. Just changing the direction of the field will cause problems.
When Li Hai piloted the temporary No. 01 J-6 to once again fly through the field at a low altitude of 50 meters, everyone saw the engine spraying black smoke.
"Lindong! Your engine is emitting black smoke!" Wu Guangwei quickly reported the situation to Li Hai.
Li Hai quickly checked the condition of the engine and found that the speed was normal. Just as he was about to report, the pointer of the tachometer suddenly started to shake.
Immediately afterwards, there was a setback in the power and the engine surged!
"Engine surge! I'm landing!"
Li Hai dealt with it decisively. At this time, he had just entered the sky above the runway. Normally, he should quickly climb to altitude and then go around to land.
However, he knew very well that the temporary No. 01 J-6 would probably not give him a second chance to land.
Therefore, he landed decisively and directly.
Dang Weimin's heart was in his throat. He clearly saw Li Hai directly press the nose of the aircraft to lower the height, and at the same time launch the landing gear.
At only a height of fifty meters, this is a very dangerous move.
Just when everyone was stunned and worried that Li Hai would hit the runway, the nose of the plane suddenly raised, and then quickly suppressed it, keeping it at the landing angle.
The landing gear tires of the temporary No. 01 J-6 came into contact with the runway surface smoothly, and then quickly entered the taxiing state.
The tail dragged a long black smoke, which became the most shocking scene today.
"Tower, it seems that there is still a problem of inconsistent oil quality."
After the plane stopped, Li Hai said helplessly.
"Stop the car and leave the plane. The cause of the failure will be handled by maintenance."
