The takeoff trajectory of the No. 02 J-20 improved test aircraft is a 90-degree broken line, in the shape of an "L". At the moment of vertical climb, the nose of the aircraft is in place instantly, and the elevation angle is almost within one second. It goes from zero degrees to ninety degrees with almost no transition in between.
It is said that apart from the J-20, the only one in the world that can do this is the US military's F-22A.
Li Zhan had no intention of being cool, but during the test flight, he usually needed to perform a large number of large overload maneuvers in order to fly out of the flight envelope. Most fighter jets can climb vertically after takeoff, but most fighter jets require a long process from level flight to a ninety-degree elevation angle.
Not only in terms of power, but also in terms of aerodynamic appearance, the J-20 has reached a height that is unimaginable by ordinary people. Not to mention power, the aerodynamic appearance is definitely better than the F-22A. As for the power system, Li Zhan knew what engine the modified J-20 he was driving used, but he couldn't say, and no one could say.
However, people like Zhang Xueyang are veterans, and they can tell at a glance that the thrust is much greater than the models already in active service, and the color of the tail nozzle is a strong proof. After making eye contact for a few moments, we all had the same answer in our hearts.
Although they were all members of the Air Force, they are now members of the Navy. Even Zhu Wei knows that he will most likely stay and work at HNA. After the role change, they can't help but think of something that the officers and soldiers of the entire Hainan Airlines and even the Navy are eagerly looking forward to - when will the Navy's fourth-generation aircraft be released?
Look at the J-20 in the sky. Look at the right-angle vertical climb just now. The super maneuvers displayed make these veteran flying sharks who are well versed in air combat envious.
As far as air equipment is concerned, the Air Force has always been ahead of HNA until now.
In the air, Li Hai also saw the dashing takeoff of the No. 01 J-20 modified test aircraft. He was more shocked than envious. He even regretted choosing HNA for a moment. If you choose the Air Force, you may have the opportunity to fly such an excellent fourth-generation aircraft.
These thoughts only exist for a moment.
When he saw Li Zhan catching up quickly, he changed his mind and continued to turn at a wide angle at full speed. The airspeed of the aircraft would decrease when it turned. In order to maintain the airspeed, Li Hai gritted his teeth and stamped his feet and turned on the afterburner!
The engine roared violently and quickly pushed the aircraft to subsonic speed, causing the turning path to change. Li Hai steadily controlled the lever and pedaled the rudder, allowing the plane to complete the turn according to his wishes.
When he resumed level flight and flew towards the sea, he suddenly found that the No. 01 J-20 modified test aircraft appeared in front slightly higher than him, and he was suddenly startled. He didn't see when and how Li Zhan grabbed the front position.
Li Zhan's voice came, "Three turns on the hole, you did a good job with this U-shaped turn. You can obviously do it very well. You have to have confidence in yourself. Drive in the 180 direction, keep the altitude and do the basic moves again." .”
"Yes, heading 180, keep the altitude and do the maneuvers, it's over!" Li Hai was encouraged and full of confidence.
He saw Li Zhan slow down his airspeed, and after a few seconds, he passed to the front. At this time, we have entered the airspace over the Bohai Sea. Most of the airspace is training airspace for the troops, and the routes of civil aviation aircraft are accurately restricted to a small range. Sometimes, military routes and civilian routes overlap, but there is a height difference. The traffic in this airspace is really busy.
When Li Hai looked down, he saw a commercial aircraft directly below, with a heading of about 210 degrees and an altitude of about 2,700 meters, indicating that it was a flight that was performing landing procedures. No wonder Li Zhan asked him to maintain a high altitude, otherwise he might invade the civil aviation route by flying randomly.
But there was no need to worry too much. The civil aviation plane Li Hai saw had received instructions from air traffic control a few minutes ago, requiring it to maintain an altitude so as not to affect the normal training of the troops.
According to the requirements, Li Hai completed a series of flying movements, which were basically the same as what Shi Leilei had assessed him earlier. On this basis, Li Hai added a pendulum and a barrel roll. These two movements are aerobatic movements, which new recruits will learn only after they leave the army. However, after the reform, the army's new training changed, and all aerobatics were included in the new training content.
In other words, new recruits can immediately follow the veteran pilots for tactical training after arriving in the combat unit. The resulting change is that new training takes longer. This is also the reason why Li Hai’s classmates continue to receive training at the base after they release their solo careers.
Li Zhan was observing from a height of two hundred meters higher than Li Hai. He was satisfied with every flying movement of Li Hai, and it was not as bad as Shi Leilei and Zhu Wei said.
"Everything was done very well. Three turns on the hole. After returning to the field, compare and analyze with your instructor to find out the reasons. The most important thing is to have confidence in yourself. Pilots must have strong self-confidence." Li Zhan said .
Li Hai replied, "Understood! It's over!"
Li Zhan urged, "Dong Sanguai has set up a good plane, you have to treat her well and don't mess with her!"
"Yes! Please rest assured, chief!" Li Hai could not wait to promise, patting his chest.
"Tower, I'm going back to Beiku directly. Give me the route information. It's over." Li Zhan called Zhang Xueyang.
Zhang Xueyang was helpless and had no choice but to say, "Dongyao, you can return as planned. The flight plan remains unchanged. It's over."
"Return as planned, Dong Yao understands!" Li Zhan took out his lap board and pointed at the flight chart, and selected the planned flight route. All relevant information came out and was updated in real time. This is the super power of the fourth-generation aircraft. Battlefield situational awareness.
Zhang Xueyang said, "Lao Li, I wish you good luck!"
"Okay, I wish you all the best."
The No. 01 J-20 modified test machine adjusted to the 270 direction, then quickly climbed to an altitude of 12,000 meters, and then entered supersonic cruising state. The rumbling sound of supersonic flight hit the Bohai Sea in waves, and ships on the water could clearly hear the sound.
Listening to the faint noise of supersonic flight, Shi Leilei from the control tower grinned and said, "The J-20 is becoming more and more perfect."
"Stop thinking wildly. Your superiors will not let you go back to Beiku. Just wait for Hai Sidai." Zhu Wei said with a smile.
Shi Leilei smiled and said nothing, of course he knew, but he couldn't help but be envious, really envious!
"Three turns in the hole, return to the field. Don't make four turns, just land directly." Zhang Xueyang gave the order to Li Hai.
Li Hai was stunned for a moment and quickly replied, "We will land directly after returning to the field. Dong Sanguai understands!"
Zhu Wei pointed to the small red aircraft representing No. 037 J-7EGGH on the three-dimensional display screen and asked, "Stone, what do you think?"
"What else can I say? Of course I'll let him pass." Shi Leilei spread his hands and said, "Brother 1 doesn't have any objections anymore, so what else can I have?"
Zhu Wei said, "This time's performance is completely different from the last time. It's Lao Li who has a sharp eye and sees the fundamentals at a glance."
"What's the basis?" Shi Leilei didn't understand.
Zhang Xueyang pointed to the small red plane that was returning to the field on the three-dimensional display screen, and said with a smile, "This guy's skills are very good, but his performance is unstable and he is easily affected by the outside world, which means he has encountered a bottleneck. When did you arrive? Have you encountered a bottleneck?"
After frowning and recalling, Shi Leilei said, "Let's go to Beiku."
"Have you been in the army for a year or two?" Zhang Xueyang said, "It shows that this kid is very talented, and his future achievements will definitely be higher than those of you and me."
Zhu Wei smiled and nodded in agreement.
Shi Leilei understood, "No wonder Brother Yi values him so much."
No. 037 J-7EGGH entered the standard glide line. The aircraft weighing less than ten tons swayed slightly in the low-altitude airflow. Li Hai concentrated on controlling the two poles and two rudders to keep the aircraft stable. This time he finally found the feeling of flying. The so-called integration of man and machine, he has figured out some ways. The last time I flew, I was guided by the plane. This time, I started to find the feeling of fusion. The two are completely different.
The landing gear tires lightly touched the ground, and after retracting the full throttle, the car continued to brake. It continued to taxi for more than 700 meters before the speed dropped to the standard of 20 kilometers per hour, and then drove off the runway to the independent hangar. When only one of his planes lands, the parachute does not need to be opened to avoid wasting resources.
The landing like a dragonfly on water made Zhang Xueyang and the other three nod frequently. The skill of a pilot is often reflected in some simple actions. Sometimes you fall asleep on a commercial airliner and don't notice the plane landing, and sometimes you are woken up and startled. The difference lies in the skill of the pilot.
"This kid has figured out the ropes." Zhu Wei said with a smile, "Shitou, you will feel much more relaxed."
Shi Leilei said with a wry smile, "You forgot, there are two old Dolphins who have never flown a fixed-wing fighter. This is the real headache."
Zhang Xueyang pointed to the No. 037 J-7EGGH that had slid to the independent hangar in the distance, and said, "Isn't there a ready-made assistant instructor? The theoretical classes for the students in the growth class are mainly based on the J-15, and Li Hai's He has a solid theoretical foundation, let him help you.”
After a pause, he said, "Just teach them. If they can't keep up, I'll beat them back."
Zhu Wei couldn't help but frowned, lowered his voice and said, "Old Zhang, I suggest you be cautious about this matter and consider our relationship with the East Ship."
Since the last time he was injured, Zhang Xueyang's temper has also changed somewhat, and his behavior has also changed from the previous cautious and tactful style. He actually behaves like Li Zhan. But having said that, a cautious and diplomatic character is not suitable for a military chief.
"Let's see and then talk." Zhang Xueyang said, "Since we let them come, of course I hope they can successfully obtain the qualifications for landing on the ship."
Zhu Wei nodded slightly, "Of course it is. If our Flying Shark Army wants to grow and develop, we cannot do without the support of our brother units."
There are three gangs of heroes, let alone brothers.
