After saying that, climb the escalator and get into the front cockpit.

"Okay!" Zhou Hai responded, carrying his training bag, came to the back seat area, and followed the escalator to enter the cockpit.

The wide winter clothes and training bags make the narrow cockpit a little crowded.

However, none of these matters.

Now is a historic moment. This is the first time he has been in the cockpit of the sixth grade in his life.

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

“Stuck the bag in the back seat space.”

After the glass compartment was closed and closed, Li Fu shouted to Zhou Hai, shook the hand pump and turned on the fish scales.

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

Afterwards, Li Fu checked whether the instrument pressure mercury and intake pressure gauge were normal. After confirming that there was no problem, press the engine start button according to the operating requirements of the specifications.

"hiss!"

The spiral ignition ring caused the spark plug to ignite, high-pressure air entered the engine, and a noisy and sharp sound came out, the Piston-6 aviation engine was successfully activated, and the hydraulic double-blade propeller rotated counterclockwise from slow to fast.

"boom!"

After Li Fu added an enlarged throttle valve, a few seconds later, a unique roar was heard from the entire star nine-cylinder engine, and the high-speed rotating double-blade propeller rolled up turbulent flow.

"We're leaving."

Holding the joystick tightly and stepping on the rudder, Li Fu drove Chu Jiao Liu under his body and said to Zhou Hai, then slowly drove away from the huge shed-type tarmac.

At this moment, five ground crew members lined up outside the apron raised their right hands and saluted Chu Jiao Liu.

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

Seeing this, Zhou Hai, who was sitting in the back seat, also raised his hand to greet him.

"Call the tower, requesting takeoff on the 12th."

After leaving the apron and driving along the taxiway at a speed of 20 kilometers per hour, Li Fu turned on the onboard radio communication equipment, connected to the military encrypted channel, and called the airport tower.

The airport tower controller immediately replied: "No. 12, the southwest wind is light, the wind speed is 3.3 meters per second, the gust is 5 meters per second, and the field pressure is 1014, and the takeoff is allowed."

"Received on the 12th and prepare to take off."

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

"boom!"

The sound given by the flight simulator is exactly the same. The first sixth front nine-cylinder star engine, after the initial seemingly weak roar, immediately burst out with a roar full of surging power, and rolling black smoke

This extremely real voice makes people excited.

A layer of industrial salt was sprinkled on the airport runway used for deicing. The whole army green primary school teacher gradually accelerated, and the main and auxiliary landing gear tires rolled at high speed when they contacted the ground.

accelerate!

accelerate!

accelerate!

A feeling of pushing back that I had never experienced before was applied to Zhou Hai. He clenched his hands, his eyes stared at the real scenery that was rapidly regressing around him. His ears were filled with deafening roar of engines, and he felt that the blood in his body seemed to be burning.

Holding the joystick tightly, Li Fu's face was calm, and after looking at the airspeed meter, he had reached the critical speed of 135 kilometers, so he pulled the lever to raise his head decisively.

In an instant, as the fuselage angle of attack changes, the left and right metal single wings divide the airflow, creating a pressure difference and providing lift.

The large metal bird weighing more than one ton spreads its wings like an eagle, leaping gently to face the sky.

"Zhou Hai, how do you feel?" Li Fu looked calm, looked at the quickly passed scenery and the aviation school airport, and asked Zhou Hai.

Zhou Hai held his breath and looked around, quietly recalling the takeoff process, and said, "It feels good, especially good, but Master, what exactly are we doing here?"

flight!

This is what he has always pursued and the dream he was fascinated by - flying.

Moreover, it is not illusory simulated data.

reality!

Unparalleled reality!

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

Learn to fly?

It does not exist.

See the scenery?

Expensive aviation fuel and aircraft are not for you to see the scenery.

"After passing the flight simulation assessment, you are now promoted to a senior flight student. We have to go to the Danzhen training base located in the north, where most senior students are there. If you are lucky, we will still encounter surprises."

Li Fu smiled faintly and steadily controlled the fuselage to climb up, responding: "When you arrive at the base, you will be given a special flight gear."

"Danzhen Training Base?" Zhou Hai was stunned for a moment when he heard Li Fu's words, thinking about it and understanding much.

No wonder!

After staying in the aviation school for so long, he rarely saw senior flight students, and the attendance rate at the aviation school airport was not high, so he usually only had a few first-time sixth flights.

Dan Town, this inconspicuous place, is located at the northernmost end of the motherland and is less than 100 kilometers away from the national border. Zhou Hai never expected that the aviation school would establish a flight training base in this small place.

As for the so-called surprise?

As a standard modern young man, Zhou Hai is very lazy and too lazy to guess.

"I don't care about these things, I'll take you to experience the flight first. There's nothing fun in flight simulation."

Li Fu did not explain too much, and said casually, pulling the rod and stepping on the rudder. The sixth junior student carrying the two under him immediately responded, tilting to the left and flying backwards.

There was a dizzy moment in the cabin, and Zhou Hai was bound by a seat belt. His eyes were seen through the glass cockpit and saw the vast earth below.

"Although it is a propeller aircraft designed and manufactured in the 1950s, it conforms to the theory of energy maneuverability, has good handling and flight performance. When climbing, the energy lost can be negligible. As long as the fuel is sufficient, it can be kept in the climbing state. Tell me how you understand the theory of energy maneuverability."

Li Fu, wearing a anti-lood suit, explained while controlling the body as he pleased.

Use the right hand to force the push rod, the left hand to lift the throttle valve, the left foot to fill the rudder, the whole frame will resume horizontal flight instantly, and then climb head-on.

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

"Energy maneuver theory is the main design idea core of the third-generation fighter jets in the aviation industry and has an important influence on the fourth-generation fighter jets. The core of its theoretical core is described mathematically - the remaining power of the fighter jet unit = thrust - drag multiplied by speed/weight."

The remaining power of fighter jets is the core of the entire energy maneuver theory.
