In the early morning, something mist-like appeared over the base, which was fine snow, so the sky that should have been bright turned gray.
Because the East Eighth District time is used, it is actually 8 a.m. now.
Li Hai stood next to J-15S No. 311 with his flight helmet in hand, and Dang Weimin stood beside him.
Two Z-20 general tactical helicopters of the Army Aviation Force took off with a slight nod of their noses. They completed the formation during the take-off stage and then accelerated to fly west.
Li Haiqing clearly saw a heavily armed soldier sitting next to the wide open hatch, with the muzzle of a sniper rifle hanging around his neck pointing downwards at the ground.
Each Z-20 carries a squad of force scouts.
Party Weimin asked, "Is that to cooperate with our test flight?"
They all saw this small assembly of the army troops. It only took five minutes from beginning to end. The speed made Li Hai and Li Hai stunned.
"How do I know? The test flight content did not mention the cooperation of the Army troops." Li Hai said.
The party for the people said worriedly, "But their course is the same as ours, and they are afraid of a high degree of conflict."
"It's unfounded to worry. The air traffic control station at the base is not just for food." Li Hai said.
Dang Weimin smiled and said, "Aren't we going to use out-of-defense attack munitions? It's normal to have a ground command unit."
"Don't guess, four or four!"
The two continued to wait.
The Peace Base tower is different from the general air force station tower. It is a backbone station of the Western Air Traffic Control Center and can also be regarded as a sub-center. It not only commands and controls military aircraft, but also always pays attention to the situation of civil aviation and coordinates military and civilian affairs at any time.
aviation activities.
Because the area where the Peace Base is located is too big!
That’s why it’s called an air traffic control station or air traffic control center, not a tower.
In short, the tower of Heping Base is multi-functional. It covers all the flights and takeoffs and landings of military aircraft. Moreover, military aircraft coming from other areas must change their wave number when they arrive here and accept the command of Heping Air Traffic Control Station.
.
Therefore, it is known as North Library in the North and Peace in the South.
At 9 o'clock in the morning, Li Hai's crew received the order. They, the maintenance team, and the ammunition team checked the condition of the fighter jet for the last time and opened the external hard safety of all ammunition.
Having completed all preparations, they quickly boarded the plane and exited the hangar under the command of the signal conductor.
Two PL-10E combat missiles and two undefined standoff attack munitions are the mounted munitions for this test flight.
The former is very familiar. It is a very mature fighting missile and has formed a family. Fighting missiles are commonly used by our military’s fighter planes, including the J-20.
The two PL-10Es are mounted just to deal with emergencies. The main task is to test-fire new stand-off attack ammunition and test the fit between the fighter aircraft and supporting ammunition.
This is just one of the contents of today's test flight.
Because it involves live ammunition shooting, the order is placed first. There is also a base leader sitting here at the air traffic control station, always paying attention to the situation of the ground terminal of the sensor system operated by Yi Xiaoyi's team.
The weather was not very good and the visibility was relatively low, but it was more in line with the test flight requirements.
Zhou Hang was the commander. After all departments were ready and the green light was given, he called Li Hai: "Three, three meters crosswind, two-thirds standard air pressure, ready to take off."
"Three meters of crosswind, two-thirds of the standard air pressure, Sanyaoyao understands!" Li Hai replied, checking the data on the flight HUD, and he had a clear idea.
The average altitude of the area where the Peace Base is located is 4,500 meters.
Like other plateau airports, the flight runway of Heping Base is also very long, reaching 5,500 meters. This length is capable of taking off and landing -20 large transport aircraft.
The altitude of the Beiku area is much lower. The extended runway can reach 4,100 meters and can even take off and land super-heavy transport aircraft such as the An-225.
Li Hai turned on the afterburner and stepped on the brakes. The engine's efficiency was obviously much lower than in the plain area, and the speed came up slower.
When the brakes reached the critical point, Li Hai released the brakes. The nozzles of the two turbofan-10 Taihang aircraft engines suddenly opened from the smallest to the largest diameter, and the hot tail flames spurted out, instantly bursting out with powerful forward thrust.
Due to inertia, Li Hai and Dang Weimin's bodies were pressed against the backs of their chairs. The fighter plane accelerated and began to taxi. Within 400 meters, Li Hai pulled up the nose of the plane, which surprised Zhou Hang and others who were used to seeing land-based fighter jets taking off.
The person took a deep breath.
The J-11B equipped by the Western Falcon Brigade is relatively powerful. When they were stationed here for training, they did not dare to pull the nose of the aircraft over such a short distance. This is a plateau base at an altitude of 4,000 meters.
Who dares to pull the nose of the aircraft without sliding for seven or eight hundred meters? If it is fully loaded, it will be a thousand meters away. If it is a fighter jet like the J-7 or J-8, it will have to slide for one thousand and eight hundred meters without a load.
Dare to pull the nose of the plane and take off.
However, the J-10C is an exception. This guy has the advantage of aerodynamic shape. Under the standard load condition, it can pull the nose of the aircraft from 600 to 700 meters.
Yi Xiaoyi said, "The J-15 has a larger wing area and a much better lift coefficient than the J-11. It is a carrier-based fighter."
When he said this, Zhou Hang realized, yes, this is a carrier-based fighter jet, and the total runway on the aircraft carrier is 180 meters.
In addition, it is an afterburner take-off. From this point of view, the take-off distance can be considered quite satisfactory.
Of course, this is the case. Li Hai is not a fool. This is his first time taking off from a plateau airport and he has brought live ammunition, so he must proceed with caution.
Li Hai continued to climb to 6,000 meters above sea level, which is 2,000 meters above ground level. This is the difficulty of plateau flying. The sea height data is pretty good, but the space that can actually be used is very limited. Always pay attention to the four or five thousand meters.
Meters altitude peaks.
Zhou Hang ordered him to continue flying north for fifty kilometers and then turn left to direction 270.
Li Hai checked the aeronautical chart on the lap board. If he kept flying on this heading, the route would be basically consistent with the ridgeline on the north side of the Wakhan Corridor.
However, the route is not like this. The test flight route has been determined long ago. Zhou Hang cannot change it temporarily, and neither can Li Hai.
The only person with this power was Yi Xiaoyi. He made a request, and the peace air traffic control station coordinated and arranged the route. In short, the army should assist the flight test team in completing the test flight of the J-15S.
Obviously, Yi Xiaoyi has no intention of changing the route.
Zhou Hang issued instructions according to the time nodes, and Li Hai changed the course, altitude, and speed according to the time nodes, as accurately as a sniper shooting a coin 800 meters away.
45 minutes later, the position of J-15S No. 311 was already 15 kilometers east of the entrance to the Wakhan Corridor, heading 270, altitude 5,500, and speed 600.
Next it’s time to see the real chapter.
Zhou Hang issued a new order, "San Yaoyao, be ready to enter the mountain."
"San Yaoyao understands and is ready to go into the mountain." Li Hai replied.
At this time, he saw two black Z-20 general tactical helicopters flying towards each other. Visually, there was a height difference of 500 meters.
Judging from the time and the speed of the Z-20 general tactical helicopter, they should have penetrated about 150 kilometers into the Wakhan Corridor, just within the combat radius of this type of helicopter.
It was Li Hai's crew's turn. J-15S No. 311 maintained speed and entered the Wakhan Corridor.
