After saying that, he climbed up the escalator and got into the front seat cockpit.
"Okay!" Zhou Hai responded, carrying his training bag, came to the back seat area, and climbed into the cockpit along the escalator.
The thick winter clothes and training bag made the narrow cockpit a little crowded.
However, none of this matters.
Now is a historic moment. This is the first time in his life that he has sat in the cockpit of Junior Education 6.
After Li Fu and Zhou Hai boarded the plane, the five-person ground crew team closed the glass cockpit, removed the escalators on the edge of the fuselage, and lined up outside the No. 4 shed-style apron.
"Stuff the bag in the back seat space."
After the glass cabin was closed, Li Fu shouted to Zhou Hai and shook the hand pump to open the fish scales.
Zhou Hai, who looked a little excited, nodded, took off his training bag containing personal belongings, and stuffed it into a narrow space at the end of the back seat.
Later, Li Fu checked whether the instrument pressure mercury column and the intake pressure gauge were normal. After confirming that there was no problem, he pressed the engine start button in accordance with the standard operation requirements.
"hiss!"
The helical ignition ring caused the spark plug to ignite, and high-pressure air entered the interior of the engine. A noisy and sharp sound came out. The piston-aviation engine was successfully started and activated, and the hydraulic two-blade propeller rotated counterclockwise from slow to fast.
"boom!"
When Li Fu increased the throttle, a few seconds later, the entire star-shaped nine-cylinder engine emitted a unique roaring sound, and the high-speed rotating two-blade propeller rolled up waves of turbulence.
"We walked."
Holding the control stick tightly and stepping on the rudder, Li Fu drove the Chujiao Liu underneath him, said something to Zhou Hai, and then slowly drove away from the large shed-style apron.
At this moment, the five ground staff lined up outside the tarmac raised their right hands at the same time to pay a military salute to Chu Jiao Liu.
Li Fu looked serious and saluted the five ground staff.
Seeing this, Zhou Hai, who was sitting in the back seat, also raised his hand to salute.
"Call the tower and request takeoff on the 2nd."
After leaving the tarmac and driving along the taxiway at a speed of twenty kilometers per hour, Li Fu turned on the onboard radio communication equipment, accessed the military encrypted channel, and called the airport tower.
The airport tower controller immediately replied: "No. 2, light wind from southwest, wind speed 3.3 meters per second, gust 5 meters per second, field pressure 04, permission to take off."
"Received on the 2nd, ready to take off."
After getting the answer from the tower controller, Li Fu looked calm. He held the throttle in his left hand and slowly increased it. He held the joystick in his right hand to control the war eagle under him.
"boom!"
Exactly the same as the sound given by the flight simulator, the Chujiao Six front-mounted nine-cylinder radial engine, after an initial feeble roar, immediately erupted into a powerful roar and emitted billowing black smoke.
This extremely real voice is heart-warming.
On the airport runway that was sprinkled with a layer of industrial salt for de-icing, the entire military green JJ-6 gradually accelerated, and the main and auxiliary landing gear tires came into contact with the ground and rolled at high speed.
accelerate!
accelerate!
accelerate!
A pushing feeling that he had never experienced before acted on Zhou Hai's body. He clenched his hands tightly and stared at the real scenery that was rapidly retreating around him. 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 control stick tightly, Li Fu looked calm. He looked at the airspeed indicator and saw that he had reached the critical speed for takeoff of 35 kilometers. He decisively pulled the stick and raised his head.
In an instant, as the angle of attack of the fuselage changes, the left and right metal wings divide the airflow, creating a pressure difference and providing lift.
The big metal bird, which weighs more than a ton, spreads its wings like an eagle, leaps lightly, and faces the sky.
"Zhou Hai, how do you feel?" Li Fu looked calmly, looked at the ground scenery and the aviation school airport that quickly disappeared, and asked Zhou Hai.
Zhou Hai held his breath, looked around with his eyes, quietly recalled the takeoff process, and said: "It feels good, very good, but Master, what on earth are we doing here?"
flight!
This is what he has always pursued, the dream that fascinates him - flying.
And it’s not just simulated data.
reality!
Unparalleled reality!
However, there was a question rooted in Zhou Hai's heart. He still didn't understand what he was doing here.
Learn to fly?
nonexistent.
See the scenery?
Expensive aviation fuel and the aircraft's own wear and tear are not just for you to see.
"After passing the flight simulation assessment, your student status has been upgraded to a senior pilot student. We are going to the Dan Town training base in the north, where most of the senior students are. If we are lucky, we may encounter surprises. "
With a faint smile on his face, Li Fu steadily controlled the fuselage to climb, and responded: "When you arrive at the base, you will be given special flight equipment."
"Dan Town training base?" Zhou Hai was stunned for a moment after hearing Li Fu's words. He thought deeply and realized a lot.
No wonder!
After staying at the aviation school for so long, he rarely saw senior pilot students, and the airport attendance rate at the aviation school was not high, and there were usually only a few Novice Level 6 flights.
Dan Town, this inconspicuous place, is located at the northernmost tip of the motherland, 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 youth, Zhou Hai was too lazy to guess.
"Ignore all of this, I'll let you experience flying first. There's nothing fun about flight simulations."
Li Fu didn't explain too much, just said something casually, suddenly pulled the lever and stepped on the rudder. Chu Jiao Liu, who was carrying the two people under him, immediately reacted, yawed to the left and rolled, in an inverted flight state.
The cabin was spinning for a while. Zhou Hai was restrained on the seat by a safety belt. His eyes looked through the glass cockpit and saw the vast land below. ..
"Although Chujiao Liu is a propeller aircraft designed and manufactured in the 1950s, it conforms to the energy maneuver theory and has good controllability and flight performance. During the climbing action, the energy loss is negligible. As long as the fuel is sufficient, it can be maintained continuously. In the climbing state, tell me how you understand the energy machine theory."
Li Fu, wearing an anti-German suit, was explaining and controlling the machine as he pleased.
The right hand pushed the stick, the left hand raised the throttle, and the left foot was full of rudder. The entire JJ-6 instantly returned to level flight, and then climbed head-on.
After 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 core of the main design ideas of the third-generation fighter aircraft in the aviation industry. It also has an important influence on the fourth-generation fighter aircraft. The core of the theory is described mathematically - force-drag multiplied by speed/weight."
The remaining power of a fighter unit is the core of the entire energy maneuver theory.
PS: I have to go out of town for something today, so I will have three updates tonight, so I will sneak away first.
