It is also because of this theory that John Boyd, who has been dead for nearly 20 years, has become a great man in the field of human aviation, reaching the pinnacle and influencing the development of human aviation.

How influential is this theory?

Every third-generation fighter designed by countries around the world has energy maneuvering as the core, and it is completely impossible to circumvent this theory, pressing the theory of the bombing mechanism to the ground and rubbing it back and forth.

Whether it is the American magic weapon F-15 "Eagle" and F-16 "Falcon", or the F-18 "Hornet" family composed of the air dream team, or the noble and elegant Su-27 family, the domestic J-10 series and J-11 series, as well as a large number of mainstream fighters in Europe and the United States.

The category of third-generation fighters is based entirely on the theory of energy maneuvering.

The whole theory, until the maturity of over-the-horizon air combat and missile technology, the emergence of the first fourth-generation stealth fighter F-22 'Raptor', the importance and influence of the theory of energy maneuver declined, and people turned their attention to stealth performance and over-the-horizon air combat.

But even so, the theory of energy maneuvering still occupies an important influence in today's aviation field, and even the design of the fourth-generation stealth fighter cannot be avoided.

No one dares to guarantee that in future wars, there will be no close-range combat air combat, and it is precisely for this reason that the three fourth-generation stealth fighters currently in service in the world have placed special emphasis on maneuverability and integrated the theory of energy maneuverability into it.

This theory is the key knowledge that needs to be learned in the junior flight training stage.

Zhou Haiqing clearly remembers every word and punctuation mark about this theory, and has his own understanding of it.

Close combat air combat, this type of combat, is still a forbidden area in the theory of energy mobility, an inviolable territory - whichever side has the highest remaining power of fighter units wins.

Energy!

The most important energy!

The whole theory, based on the physical laws of thermodynamics, cannot be crossed or violated.

"Well, yes, that's true. In close combat, the most important thing in flying is to maintain energy, you must not be rigid, you must be improvised, you must use various skills, you must predict how the enemy will fly next, see farther, and plan slowly, rather than rushing for quick success."

Hearing Zhou Hai's answer, Li Fu handily held the joystick, nodded, and explained while controlling the Chujiao Sixth to climb with his head up and roll over: "You see, let's assume that there is an enemy aircraft with the same performance in the rear, and when it bites our tail, remember, absolutely don't panic, we can use the high yoyo tactic, pull the rod to climb, exchange speed for altitude advantage, and at the same time roll down with the cockpit facing down, observe the flight attitude and trajectory of the enemy aircraft." ”

Lectures on real machines, with a tumbling experience, this feeling is definitely not something that normal people can enjoy.

Inside the narrow cockpit, looking at the outside world, it was almost a whirlwind, and in an instant, Zhou Hai was in an upside-down state again, with his head facing the earth and his buttocks facing the sky.

If you are an ordinary person with a bad sense of space, at this moment, you will have to get dizzy, and there is a high probability that you will misjudge your position and direction.

Moreover, this is only the simplest beginner aircraft, not a modern fighter in the true sense of the word.

Below the first six of the sect, there seemed to be an invisible enemy plane, which was caught off guard and swept over its previous position, losing its target and advantageous attack position.

The roles of the hunter and the prey changed abruptly.

"After observation, we must react immediately, without hesitation, assuming that the target is in a state of short level flight, looking for our traces, we fly out of a large angle arc trajectory, and then exchange altitude for speed advantage, and obtain an attack position, biting the enemy's tail."

Li Fu's face was calm, and he controlled the Chujiao 6 to enter the dive acceleration stage, the nose of the plane was aimed at the front, and then he flew out flat:

"Of course, in practice, you can make a sharp turn on the left side + climb and roll at a large elevation angle, or you can make a drum maneuver, dive to make a low yoyo maneuver, etc., don't be rigid and stiff. But I want to warn you that the low yoyo maneuver will deplete your energy in exchange for a short attack slot, and you should never use the low yoyo unless you have the intention of killing with one hit. ”

99% of fighter pilots will choose the former for the two air combat maneuvers of high yoyo and low yoyo, because the former's energy budget is basically balanced, and if it is a fighter equipped with a vector engine, it can even be surplus.

And the low-yode air combat maneuver, in exchange for speed, then speed for height, and finally in exchange for a firing window of less than a few seconds.

The entire maneuver will greatly consume the energy accumulated by the fighter.

Unless it has reached a desperate situation, unless it has the belief that one blow will kill, it is completely an act of seeking death to make a low maneuver under normal circumstances.

"I see."

Hearing Li Fu's concept and experience in air combat, Zhou Hai's face showed seriousness, he was shocked, took a deep breath, and kept in mind all the knowledge that had never been recorded in these books.

Experience!

These all belong to Li Fu's flight experience, which is close to actual combat rather than the theoretical knowledge given in books.

"We are air force pilots, and we are fighter jets, and we are by no means the group of people in civil aviation who only know how to look at instruments and take off and land, you know? Fight! Our duty is to fight, our mission is to fight, and everything we seek is to fight, to fight in the sky, not to fly rigidly and rigidly. ”

Li Fu's face revealed a hint of coldness, his eyes were solemn, and the elegant aura in his body disappeared, replaced by a solemn aura, and slowly transmitted his accumulated experience to Zhou Hai: "Zhou Hai, what is the core of air combat?" It is to do everything you can to destroy the enemy and achieve victory. ”

Fight!

This is the real duty and mission of fighter pilots in the Air Force, and it is the core factor that the danger of this profession has always been high.

What is a Civil Aviation Pilot?

During the whole flight process, you only need to take off and land, and the rest of the time you only look at the instruments, and everything is left to the automatic flight pilot.

Hearing Li Fu's words, Zhou Hai's eyelids jumped, and he secretly smacked his tongue in his heart, he didn't expect his master to have such a side.

Rigid and stereotypical?

This metaphor, Zhou Hai could only be silent and did not dare to say anything.

It's good that the civil aviation is also a serious pilot, so let's go?

I have always heard that Air Force pilots look down on civil aviation, but now I see that this is indeed the case.

However, for the experience taught by Li Fu, Zhou Hai is very useful.

Fight!

Indeed, the mission and duty of air force pilots, especially fighter pilots, is to fight, and to use the skills and knowledge they have learned to defend this clear blue sky – their own.

"Do you remember what I said?" Li Fu manipulated the Junior Sect Six to maintain a horizontal and stable flight state, looked out the window, looked at the sesame-like buildings on the ground, and asked Zhou Hai.
