After the words fell, he climbed the escalator and sat in the cockpit of the front seat.

"Good!" Zhou Hai responded, carried the training bag, came to the back seat area, and boarded the cockpit along the escalator.

Generous winter coats and training bags make the cramped cockpit a little cramped.

None of that matters, though.

This is now a historic moment, this is the first time in his life that he has sat in the cockpit of the sixth year.

After Li Fu and Zhou Hai boarded the plane, the five members of the ground crew closed the glass cockpit, removed the escalator on the edge of the fuselage, and lined up on the periphery of the No. 4 shed apron.

"Stuff the bag in the back seat."

After the glass cabin was closed and closed, Li Fu shouted at Zhou Hai, shaking the hand-crank pump to open the fish scales.

Zhou Hai, whose face was a little excited, nodded, took off the training bag containing personal items, and stuffed it into a narrow space at the end of the back seat.

Subsequently, Li Fu checked whether the instrument pressure mercury and the inlet pressure gauge were normal, and after confirming that there was no problem, he pressed the engine start button in accordance with the standard operation requirements.

"Shhh

The spiral ignition ring caused the spark plug to ignite, high-pressure air entered the engine, a noisy and high-pitched sound was heard, the piston-6 aero engine was successfully activated, and the hydraulic double-bladed propeller rotated counterclockwise from slow to fast.

"Boom!"

After Li Fu added an enlarged throttle valve, a few seconds later, a unique roar came from the entire star-shaped nine-cylinder engine, and the high-speed rotating two-bladed propeller rolled up a turbulent current.

"We're leaving."

Gripping the joystick tightly and stepping on the rudder, Li Fu piloted the junior sixth under him, said to Zhou Hai, and then slowly drove away from the huge shed-type apron.

At this moment, the five ground staff members lined up outside the tarmac raised their right hands at the same time and saluted the sixth junior teacher.

Li Fu had a serious face and saluted the five ground crews.

Zhou Hai, who was sitting in the back seat, saw this and also raised his hand to salute.

"Call the tower, request to take off on the 12th."

Driving away from the tarmac and driving along the taxiway at a speed of 20 kilometers per hour, Li Fu turned on the on-board radio communication equipment, connected to the military encrypted channel, and called the airport tower.

The airport tower controller immediately replied: "On the 12th, there is a light wind in the southwest direction, the wind speed is 3.3 meters per second, the gust is 5 meters per second, and the field pressure is 1014, and it is allowed to take off." ”

"Received on the 12th, ready to take off."

After getting the answer from the tower controller, Li Fu's face was calm, holding the throttle valve in his left hand, slowly increasing it, and holding the joystick in his right hand to control the war eagle under him.

"Boom!"

Exactly like the sound given by the flight simulator, the front-mounted nine-cylinder star engine of the First Lesson 6 burst into a roar full of power after an initial seemingly feeble hiss, and billowed black smoke came out

This kind of incredibly real sound makes people's blood boil.

On the airport runway, sprinkled with a layer of industrial salt for de-icing, the entire Army Green Junior Six gradually accelerated, and the main and auxiliary landing gear tires made contact with the ground and rolled at high speed.

Hasten!

Hasten!

Hasten!

A feeling of pushing his back that he had never experienced before acted on Zhou Hai's body, his hands were clenched, a pair of eyes stared at the real scenery around him that was rapidly retreating, and his ears were filled with the deafening roar of the engine, and he felt that the blood all over his body seemed to be burning.

Holding the lever tightly, Li Fu looked at the airspeed counter, and the critical speed of 135 kilometers of take-off had been reached, so he decisively pulled the lever and raised his head.

Suddenly, as the angle of attack of the fuselage changes, the left and right metal monowings split the airflow, creating a pressure difference and providing lift.

The large metal bird, which weighs more than a ton, spreads its wings like an eagle and leaps gently into the sky.

"Zhou Hai, how do you feel?" Li Fu's face was indifferent, he looked at the ground scenery and the aviation school airport that were passing quickly, and asked Zhou Hai.

Zhou Hai held his breath, looked around with his eyes, quietly reminisced about the take-off process, and said, "It feels good, very good, but Master, what are we doing here?" ”

Flight!

That's what he's been pursuing, a dream he's obsessed with – flying.

And it's not just ethereal analogues.

Authentic!

Unparalleled authenticity!

However, there is a question rooted in Zhou Hai's heart, he still doesn't understand, what are you doing here?

Learning to fly?

Inexistent.

Looking at the scenery?

Expensive jet fuel and the wear and tear of the plane itself are not for you to see.

"After passing the flight simulation assessment, you are now promoted to a senior flight cadet, we are going to the northernmost Danzhen training base, most of the senior cadets are there, if we are lucky, we can still meet surprises."

With a faint smile on his face, Li Fu steadily controlled the fuselage to climb, and responded: "When you arrive at the base, I will issue you special flight equipment." ”

"Danzhen training base?" When Zhou Hai heard Li Fu's words, he was stunned for a moment, thoughtful, and enlightened.

No wonder!

After staying in the aviation school for so long, he rarely saw the senior flight students, and the attendance rate at the aviation school airport was not high, and there were usually only a few beginner six flights.

Danzhen, this inconspicuous place, is located in the northernmost part of the motherland, less than 100 kilometers away from the national border, Zhou Hai did not expect that the aviation school would establish a flight training base in this small place.

As for the so-called surprises?

As a standard modern youth, Zhou Hai is lazy and too lazy to guess.

"None of this matters, let's take you to experience flying first, there's nothing fun about flight simulation."

Li Fu didn't explain too much, said casually, and slammed the rod and stepped on the rudder, and the Junior Sect Liu, who was carrying the two of them under him, immediately reacted, yawed to the left and rolled, flying upside down.

The cabin was spinning for a while, Zhou Hai was restrained on the seat by the seat belt, and his eyes saw the vast land below through the glass cockpit.

"Although the first teaching six is a propeller aircraft designed and manufactured in the fifties, it conforms to the theory of energy maneuvering, has good handling and flight performance, when climbing the action, the loss of energy is negligible, as long as the fuel is sufficient, you can always maintain the climbing state, tell me, how do you understand the theory of energy maneuvering."

Li Fu, who was wearing an anti-load suit, was explaining while controlling the body as he wanted.

The right hand pushes the rod, the left hand lifts the throttle valve, and the left foot is full of rudders, and the whole Chujiao Six instantly resumes horizontal flight, and then climbs head-on.

Hearing Li Fu's words, Zhou Hai, who leaned back, looked at the hazy and close sky above his head, nodded, and said softly:

"The theory of energy maneuverability, the core of the main design idea of the third-generation fighter in the aviation industry, also has an important impact on the fourth-generation fighter, and its theoretical core is described mathematically - the residual power of the fighter unit = thrust - drag multiplied by speed / weight."

Fighter unit residual power, which is the core of the entire theory of energy maneuvering.

PS: I have something to go to the field today, and tonight I have three consecutive shifts, so I slipped away first.
