After the BF109 controlled by Chiba appeared on the runway, it immediately took off at the fastest speed, and continued to accelerate through level flight - no aircraft could attack it at this time, because the plane would be in an invulnerable novice protection state as long as it did not fire bullets in the first five minutes.

Beside him, a plane descended in a horizontal circle.

"Which unlucky bastard... Qian Yu muttered. "It's a stall and a tailspin...

The word stall tailspin is actually divided into two parts: stall and tailspin. The stall is generally caused by the excessive ascent angle of the aircraft, which causes the air to flow through the wing in a different state than under normal conditions, which eventually causes the lift of the wing to disappear and the aircraft to fall naturally.

Tail spin is the most dangerous demon in a stall state. If the wings of the aircraft do not stall at the same time, the aircraft will spin and fall at the same time. If the pilot's mental quality is not enough, or the aircraft's performance is insufficient, then the tailspin is a death call that cannot be escaped after a stall.

Five minutes later, when the novice protection state of the aircraft ended, Chiba's BF109 had reached the ideal air combat altitude of more than 5,000 meters.

Chiba is not in a hurry to fight against others, because the BF109 itself is not an aircraft that fights bayonets with others - the kind of thing that is hand-to-hand entanglement should be handed over to the Zero fighter.

The reason why Qian Yu chose BF109 is because he intends to use the theory of energy air combat.

The energy of an aircraft is made up of kinetic energy and potential energy, and the value obtained by dividing the energy by the weight reflects the energy level of an aircraft. Those with a high energy level will be able to gain faster speed and higher altitude than the opponent through maneuvering in air combat, and they will be at an advantage. To put it in a simple formula, the one with the square of the second speed plus twenty times the height has an advantage.

Although the theory of energy air combat had not yet been studied during World War II, there were lucky people who relied on the inspiration of designers to become close to the true meaning of energy air combat theory.

For example, BF109 is one of them. With little difference in horsepower, it has top-of-the-line vertical maneuverability for climbing and diving, and its thrust-to-weight ratio is also in the best class. So it was one of the few aircraft of the World War II era that most conformed to the theory of energy air combat.

Chiba noticed a small black dot on the screen, it turned out to be an oncoming plane with a lower altitude than him, and he decided to use this plane to practice his skills.

BF109 began to dive at a small angle while firing several bullets to attract the attention of the opponent.

According to the data marked on the other party's plane by the computer, the plane opposite is a P51, which is probably someone who directly picked a top American aircraft, completely ignoring the fact that this game has corrected some performance strength for balance.

The P51 raised the nose of the aircraft and aimed at the BF108 of Qianyu, and also began to fire - but because the distance between the two sides was still five or six thousand meters, neither side could hit the other at all.

Qian Yu pulled up the nose slightly, and operated the BF109 to pass over the P51, while the P51 still continued to pull the nose higher - the nose was pulled higher than the angle that the BF109 was now in, apparently intending to make a advance.

When the BF109 came diagonally above the P51, Chiba suddenly pushed the joystick forward, and the BF109 immediately aimed in the direction of the P51 and dived down at a large angle, and the onboard machine gun was fully fired.

"Come on," Qian Yu muttered. Let me see if you're stupid..."

The P51 immediately responded, aiming its nose at the BF109 with the same full firepower. The two planes were flying in opposite directions on the same axis, and after about fifteen seconds, they collided and crashed together. At this time, it's completely a duel of guts.,Whoever avoids it first.,Whoever loses in the battle of guts.。。

Could this happen? Of course not.

After a few more seconds of flying between the two aircraft, the BF109 suddenly began to deflect sharply to the right, and the P51 immediately turned to the left to maintain the lock on the BF109. However, just as the P51 was biting on the BF109, it suddenly dropped its nose without warning and began to spin!

The P51 has entered a stall tailspin state!

"Humph!" Qian Yu glanced slightly smugly at the p51 in a tailspin state. "Death!"

The tailspin of the P51 was certainly not an accident, but was artificially caused by a thousand feathers.

The requirement for a stall is that the elevation angle is too large, and the threshold for this stall elevation angle depends on the speed of the aircraft. The smaller the velocity, the smaller the stall elevation angle. So, if you want to stall the plane, the best thing to do is to consume the speed of the plane.

There are two ways to consume the speed of an aircraft, one is to make the opponent perform a high-intensity maneuver to burn energy, and the other is to make the opponent climb at a large angle and convert speed into altitude in a short time.

In the case of an absolute advantage in height, the best option is naturally to let the opponent make an upward climbing move. Therefore, Qianyu provoked the P51 first, making it raise the nose of the aircraft and climb the altitude while attacking itself. The next series of maneuvers were also aimed at allowing the P51 to continue to raise the nose and lose kinetic energy at a faster rate. Eventually, after P51 lost quite a bit of momentum, Chiba tricked P51 into making a large left turn with a right turn. This action not only caused the P51 to lose a lot of energy, but also caused the speed of its left and right wings to be inconsistent, which eventually led to inconsistent stall times, causing a nightmare flight accident - stall tailspin. This is also the culprit that ultimately led to the defeat of P51 without a fight.

While complaining about the stupidity of the P51 pilot, Chiba pulled the nose back on, regaining his altitude while maintaining his speed at a high level.

Who's next--ah, now is not the time to think about this, and now I'm not high enough to be able to hunt safely...

Qian Yu was thinking about this when she noticed a bunch of sparks coming out of her body. The staff member who was watching from the side immediately showed a look of remorse, and then quickly pressed the index finger that Qian Yu held on the joystick, and part of the joystick immediately dented. At the same time, a translucent interface appears at the top of the screen, showing a Zero fighter.

"This is the screen that shows the upper half of the airspace behind, and judging from the picture on this screen, the opponent's Zero fighter is a little taller than you. I forgot to tell you about this function key just now, sorry. ”

Chiba immediately pushed the joystick and pulled the nose of the plane downwards to dive. On the instrument panel, the speed increases with the dive time.

Speed 300 per hour, speed 350 per hour, speed 400 per hour, Qian Yu watched the numbers on the dashboard continue to increase and continue to accelerate. The plane is still sparking, and it is clear that the speed of the opponent's Zero Battle is still faster than its own. However, this situation was within the range of Qianyu's consideration, so Qianyu still continued to accelerate very calmly, just pulling the rudder to the right a little.

Somehow, a few people came to Qianyu's side and watched his operation, not with a tone of amazement. However, Qian Yu didn't have the energy to care about them.

When the speed was increased to 550, Chiba took a deep breath and pulled the rudder back to the limit.

The BF109 soared directly into the sky and soared into the sky at an elevation angle of 90 degrees perpendicular to the bottom surface.

"Inmaiman maneuver?" The audience next to the seat of Thousand Feathers was surprised. "Does he want to do an Inmaiman maneuver?"

As they thought, after ascending more than a thousand meters, Chiba pulled the joystick back again, and the BF109 changed direction again and flew over the Zero fighter in an upside-down attitude.

"It's my turn!" In the murmur of a thousand feathers, the killing machine is clear.
