Luo Hai's subordinates are flying, and their dexterous fingers are like dancing butterflies, beating flexibly on the keyboard of the laptop.

"Wind, air humidity, atmospheric pressure and climate environment are not considered in general mathematical calculations, but this dynamic mathematical model must be considered, otherwise the dynamic mathematical model constructed will be meaningless." Luo Hai kept calculating, and suddenly, Luo Hai stopped.

"You have to find an example of air combat." Luo Hai thought to himself, and then found a video of modern air combat recorded during the Fourth Middle East War from his computer.

In the video, a squadron of Mirage IIIC fighters piloted by an Israeli pilot and a MiG-21 group of an Ethiopian-Syrian coalition group encountered, and the two sides exchanged fierce fire in the airspace within a range of 100 kilometers.

Seeing this actual combat video, Luo Hai's mind suddenly turned at high speed, with the aircraft he was piloting as the core, Luo Haitong guò air combat video, the three MiG-21 and the overall combat environment, as a mathematical model construction object,

One by one, mathematical characters appeared on the laptop screen, and then Luo Haitong guò calculator quickly calculated the results.

"Well, that's fine. With environments such as humidity, barometric pressure, and wind, the mathematical model is meaningful. After the air battle video was played, Luo Hai looked at the dense mathematical characters on the computer screen, and through the calculation method of guò calculus, Luo Hai was coming up with one mathematical result after another, and then reusing these calculation results.

The flight numbers and performance of the Mirage IIIC fighter and the MiG-21 fighter can now be found on the Internet, and after the library in the Luohaitong guò base obtained the flight numbers and performance of the two fighters, they put their flight performance and performance into the mathematical model.

Luo Hai devoted all his attention to the mathematical model of air combat dynamics, time passed slowly, and I don't know how long it took, and the work and rest horn in the base sounded.

"Luo Hai, go to sleep, Teacher Weng will come to check on the bed soon." Li Zheng, who was about to sleep, saw that Luo Hai was still holding the notebook, and immediately said.

Luo Hai's high-speed brain was looking for a number: "Well, right away." After a while, Luo Hai came up with this number, and then quickly typed it into the computer, at this time, a group of footsteps came from outside the dormitory.

Hearing this voice, Luo Hai quickly closed the notebook, and then quietly put the notebook into the carry-on space. At this time, the door of the dormitory was opened by Weng Tianping.

Luo Hai quickly closed his eyes and rested.

"Let's go." After shaking the flashlight and seeing that everyone was asleep, Weng Tianping said to the accompanying officers, and then left the dormitory.

"It's dangerous." After Weng Tianping left, Luo Hai opened his eyes and breathed a sigh of relief in his heart.

The brain was running again, Luo Hai used the gray space energy to control the laptop in the space he carried, and then recalled the video of the Israeli and Egyptian-Syrian alliance fighters in the Fourth Middle East War, and continued to build a mathematical model of air combat.

This mathematical model is very important to Luo Hai. After scientific calculations, Luo Hai can keep a cool head for a long time in the battle, and get the maximum damage at the lowest cost.

……

In the early morning, the base was wrapped in a faint cloud like a cocoon, looming, as if it was a fairyland on earth.

All the trainees of the elite class, who have fully entered the on-board training, got up the next morning and handed in the flight summary of the first flight, and then ran on the runway for morning exercises and physical training.

After an hour of physical training, everyone had dinner in the cafeteria, and then rested for half an hour, and then was led by the flight instructor again, sat on the first teaching seven, and took off on the runway in the morning breeze.

Weng Tianping stood on the simple tarmac, next to Luo Hai's instructor Zhang Wei. Looking at Luo Hai, Weng Tianping was holding an A4 paper in his hand, on which something Luo Hai could not see: "Luo Hai, an elite class student of North China Aviation Academy, because of your excellent performance on board and your heavy contribution to the national aviation industry, you are hereby approved to fly the L-15 'Falcon' senior training aircraft, and Instructor Zhang Wei will assist you, hoping that you will become an official pilot as soon as possible and contribute to the country and the people." ”

Direct flight to higher education ?!!! ――Hearing Weng Tianping's words, Luo Hai, who was left here with doubts in his heart, shook his head suddenly, what is the situation?

When many students boarded the Junior Seventh for flight training just now, Luo Hai was left behind by Zhang Wei and Weng Tianping, and at this moment, Luo Hai never thought that he had received the news of a direct flight to a senior training aircraft.

Luo Hai, who was in a daze, hadn't reacted yet, Zhang Wei on the side saw this scene, and quickly gave Luo Hai a look, seeing Zhang Wei's eyes, Luo Hai immediately reacted, straightened up, and saluted Weng Tianping: "Yes, thank you Mr. Weng, I will definitely work hard to make myself fly better and strive to become an official pilot as soon as possible." ”

"Well, Luo Hai, I hope you continue to work hard." Weng Tianping looked at Luo Hai with a kind smile on his face.

At this time, Zhang Wei on the side said, "Luo Hai, follow me." ”

Luo Hai nodded, and after saluting Weng Tianping, he followed Zhang Wei to the L-15 'Falcon' advanced training plane parked on the simple tarmac.

Zhang Wei climbed the ladder and entered the front cockpit, and Luo Hai followed closely behind and sat in the cockpit behind.

Sitting in the blister-shaped glass cockpit, Zhang Wei smiled at Luo Hai while checking the onboard equipment: "L-15 Falcon advanced training aircraft, the maximum flight speed is Mach 1.4, the ceiling is 16,000 meters, and the overload is up to 8.3G, Luo Hai, how do you feel this time?" ”

"Instructor Zhang, I have to say, you won." Luo Hai suppressed the excitement in his heart and methodically checked the onboard equipment.

Turning on the airborne photoelectric display, Zhang Wei heard Luo Hai's words and smiled: "Haha, boy, don't thank me, this is all brought by you yesterday with the Beginner Seven flying out of a bell." Subsequently, Zhang Wei ignited two AI-222-25F afterburner turbofan engines.

"Groan!" The internal fans of the two AI-222-25F afterburner turbofan engines quickly rotated, and high-quality aviation fuel entered the combustion chamber like flowing water, and a low and sharp roar appeared.

A pale blue high-temperature flame erupted from the rear of the engine in an instant, just like the tail of a comet, dazzling.

"Let's go!" Zhang Wei stepped on the rudder and brake plate, and the airborne fly-by-wire control system immediately responded, and the entire silver-gray fighter plane slid to the airport runway like a goshawk about to spread its wings and soar.

Coming to the runway, the bright eyes of the entire L15-'Falcon' refracted a dazzling light, and the mist that wrapped the base like a cocoon had dissipated, and a ray of sunlight shone in through the cracks in the mountains.

Weng Tianping stood on the runway and gave Zhang Wei and Luo Hai a thumbs up.

Zhang Wei and Luo Hai also gave a thumbs up, and then both of them put on helmet sights.

"Call the Bird's Nest, the Moon Wolf asks to take off!" After Zhang Wei brought the breathing apparatus and helmet sights, he said to the base tower.

The base tower immediately responded: "The bird's nest received, the wind force is level 2, light wind, the weather environment is good, sunny days, and it is allowed to take off." ”

"The Moon Wolf is ready to take off." Zhang Wei nodded, and then slowly pushed the throttle valve up.

"Buzz !!" The next moment, a stream of high-quality aviation fuel with a larger flow suddenly entered the combustion chamber, and the two AI-222-25F afterburner turbofan engines suddenly let out a sharp roar, like a falcon roaring in the sky, and the light blue flame at the tail of the engine was wrapped in a layer of crimson flame, just like a bright red rose, enchanting and beautiful.

The entire silver-gray L-15 'Falcon' advanced training plane was like an arrow from a string, speeding toward the front at great speed.

The tires on the landing gear rubbed violently against the runway, and under the impetus of the two AI-222-25F afterburner turbofan engines, the speed of the entire fighter became faster and faster, and like a goshawk flying with wings spread, the L-15 'Falcon' advanced training plane roared out, abruptly left the runway, and jumped into the sky.

The L-15 'Falcon' advanced training plane, which is comparable to a light fighter, climbed toward the sky at a cruising speed of 900 kilometers after leaving the base. Zhang Wei clenched the joystick on the right side and smiled at Luo Hai: "Luo Hai, how do you feel this time?" ”

"Exciting, refreshing!" Luo Hai didn't even think about it, and said out loud what he felt in his heart.

The L-15 'Falcon' advanced trainer aircraft, which flies at a maximum speed of Mach 1.4 and flies at high subsonic speed, is definitely more exciting, exciting and comfortable than the feeling of flying the Chujiao VII.

"Alright, we're going to break through the sonic boom next." Hearing Luo Hai's words, Zhang Wei nodded. Subsequently, when the L-15 'Falcon' climbed to an altitude of 12,000 meters, Zhang Wei immediately grimaced.

Luo Hai nodded, and the whole person adjusted his breathing: "Understood." ”

"Buzz!" Zhang Wei violently pushed the throttle valve to the maximum, and the next moment, the high-quality aviation fuel in the onboard fuel tank poured into the combustion chamber of the two AI-222-25F afterburner turbofan engines at the highest flow rate, like a raging flood.

The intake tract maintains the highest flow of air, sufficient oxygen and the highest flow of high-quality jet fuel, making the engine louder as if it had been stimulated.

The tail flame from the rear of the engine is more powerful, like the tail of a comet.

In an instant, the L-15 'Falcon' advanced training aircraft under him shook violently, and the speed displayed on the onboard refractive photoelectric display was like a volcano bursting, increasing at an extremely rapid speed.

In just one breath, the L-15 Falcon advanced trainer aircraft, which maintained a flight speed of 900 kilometers per hour, suddenly reached a speed of 1,000 kilometers per hour.
