Chapter 581： Negative G oil cut

In the age of propellers, aircraft engines were gasoline engines with high speed and high horsepower, but they didn't require much torque. On the ground, diesel engines were king.

The gasoline engine needs to mix gasoline and air into the cylinder. This mixing process requires a carburetor to evenly distribute the gasoline into the air. The cylinder **** in the mixed gas.

And this carburetor is realized under the action of gravity, that is to say, it can only be used directly, and it cannot be used backwards. When it is reversed, it will not work.

From the point of view of acceleration, it cannot fall into a negative g state, otherwise, the carburetor will stop working, the engine will cut off the oil, and it will stop running!

Although the Merlin engine has ended without a problem, the current air-cooled engine in the UK is also a carburetor!

Why are you not afraid of German airplanes?

This is because German engines have begun to use electronic injection. At the end of the 1930s, Germany had realized direct fuel injection on aircraft engines, eliminated the carburetor, and naturally there was no need to worry about the negative g fuel cut. Up!

This jet method does not need to be affected by gravity, so the aircraft will work in any state, as long as it does not disintegrate, it will be fine!

The current Spitfire has not yet realized this problem. The British will not solve this major problem that affects air combat until later improvements, and similarly eliminate the carburetor.

But now, in front of the Spitfire, as long as the bf109 can perform a negative-g maneuver, it can get rid of the opponent. If the opponent does not follow, it can only watch the prey escape. If it does, then the engine is cut off.

This flame-throwing wingman was hit, and made an absolutely wrong action. The engine stopped and the propeller in front did not move.

If the engine suddenly cuts off during normal training, it is not terrible. Just change back to level flight and restart the engine. Even if it fails to start in the air, it can be used as a glider and landed.

Although the technology of airplanes has made great progress now, it is still the era of propeller airplanes, with short take-off and landing distances. As long as there is a level ground, he can land.

However, now in the battle, every mistake will cost him his life.

When he finished this action, Vic only felt the blood surge, his eyes were all red. However, relying on his youth and excellent physical fitness, he quickly recovered, when he continued to look back. When I saw a Spitfire chasing me, it was falling downward.

This is certainly a good opportunity! He immediately yelled on the radio: "Klee, there is a fat sheep here, I want to go up!"

After speaking, he pushed the joystick, rolled at a large angle, and climbed up.

At this time, Klee in front also brought the operating stick, and the positions of the two sides had been swapped. Klee was the wingman and Vic was the lead plane.

This is also the advantage of the dual-aircraft formation. Generally speaking, the long-time aircraft comes to attack, and the wingman takes the cover task. However, once the shooting angle is more suitable, the wingman will switch to the offensive and the long-term opportunity will in turn protect.

This kind of combat is quite flexible and flexible.

When Vic turned to climb, he could see that the flame-out Spitfire was working hard.

On the ground, there is the help of the ground crew, but in the air, it is completely on your own.

It is not so easy to start an engine with a dozen cylinders. Now, you can see that the Spitfire is constantly emitting black smoke. Only a few cylinders are successfully started, but the rest are always Can not start.

The mechanical carburetor continues to release gasoline mixed gas inward. When the internal concentration is too high and it is not activated, another terrible phenomenon will appear.

Flooded tank.

When the amount of gasoline in the cylinder is too much, it will block the normal ignition of the spark plug, that is, the gasoline "flooded" the cylinder, which is called "flooding".

The solution is to remove the spark plug and clean it up and **** out the remaining oil in the cylinder.

In short, it is only possible to move on the ground. Now, in the sky, when the engine has flooded the cylinder, it will be completely stopped.

Vic would not be that gentleman, waiting for the opponent to start a re-air battle. At this time, Vic had already approached the opponent's nine o'clock direction, and the opponent's body was perfectly displayed in Vic's field of vision.

At this time, the pilot of this wingman also noticed Vic. He pushed the joystick to avoid Vic's attack. Unfortunately, the plane that lost power had no mobility at all!

"Tom Tom Tom!" The 20mm shaft cannon has limited ammunition. Therefore, after Vic aimed at it, it only took a short shot and fired five shells, which accurately hit the opponent's fuselage!

"Boom!" The armor-piercing incendiary bomb directly hit the fuel tank behind the opponent, even if it had self-closing technology, the effect of the incendiary bomb caused the rear fuselage of this fighter to burn!

One shot down!

Victory won, and finally he is no longer a rookie Only by shooting down an enemy plane can we become a veteran!

"Quick, roll away!" Just then, Klee's voice came from the radio.

At the same time they shot down the Spitfire, the other two fighters in the Spitfire formation had already pounced on.

There was fire in Henry's eyes, and he watched his wingman shot down, very angry.

Here, it is no longer land, but the sea. On the sea, even if it is a parachuting, it is not easy to survive. Moreover, looking at the wingman, I am afraid that there is no opportunity for parachuting.

"Da da da." Four 7.7 mm machine guns, dense bullets flew towards Vic's fighters. It seems that Vic's fighters were surrounded by this barrage, but this bf109 calmly got rid of it. Up.

In air combat, although the machine gun has a fast firing rate and many bullets, the power of the bullets is not enough. Therefore, if you want to shoot down the opponent, you must use an aerial cannon with a caliber of more than 20 mm!

This is the lesson that the Luftwaffe learned when fighting over Spain. They often found that they had hit their opponents but were unable to shoot them down because of the lack of power of their machine guns!

Therefore, they improved the cannon, which is the easiest axis gun to aim at.

However, the British Air Force has no experience in this area. They are almost restricted in this air battle.

Theoretically speaking, the performance of the Spitfire fighter is not lagging behind. Although there is some panic in the cockpit, the aircraft flies quite fluently, and the climb performance is even better. But now, they cannot discuss it in front of the Germans. To cheap!

When they catch up with the German fighter, the opponent will get rid of it. They can't keep up. Sometimes they even have a chance to fire. At most, they will hurt the opponent. However, every attack by the opponent can blow them up! Mobile users please browse and read,
