Chapter 583 Negative G Fuel Cut (Plus 3)

In the era of propellers, aircraft engines were all gasoline engines, with high speed and high horsepower, but did not 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, and the cylinder inhales the mixture.

And this carburetor is realized under the action of gravity, that is to say, it can only be used in the forward direction, and cannot be put in the reverse direction. When it is reversed, it will not work.

From the perspective of acceleration, it cannot fall into the state of negative G, otherwise, the carburetor stops working, the engine will cut off the oil, and it will stop running!

Although the Merlin engine has died out, the current air-cooled engine in the UK is also a carburetor!

Why not be afraid of German planes?

Because German engines have already begun to use EFI. In the late 1930s, Germany had already achieved direct fuel injection on aircraft engines and eliminated carburetors, so naturally there is no need to worry about negative G fuel cuts. !

(For comparison, in terms of automobiles, it was almost in the 1990s that my country began to phase out carburetor engines and adopt EFI technology.)

This jetting method does not need to be affected by gravity, so the aircraft can be in any state, as long as it does not disintegrate!

The current Spitfire has not yet realized this problem. The British will not solve this main problem affecting air combat until the later improvement, and also eliminate the carburetor.

But now, in the face of Spitfire, as long as BF109 can perform negative G maneuvers, it can get rid of the opponent. If the opponent doesn't keep up, it can only watch the prey escape.

The fire-breathing wingman was hit and made an absolutely wrong move, the engine stopped, and the propeller in front did not move.

If it is in the usual training, the engine suddenly cuts off the fuel, it is not terrible, just change back to level flight, and then 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 aircraft has made great progress now, it is still the era of propeller aircraft after all, and the take-off and landing distance is short. As long as there is a flat land, 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 surging, and his eyes were turning red, but, relying on his youth and excellent physical fitness, he recovered quickly, and when he continued to look back When I saw a Spitfire chasing after me, it was falling down.

Of course this is a great opportunity! He immediately shouted on the radio: "Klee, there's a fat sheep following, I'm going up!"

After speaking, he pushed the lever, rolled at a large angle, and climbed upwards.

At this time, Klee in the front also took the joystick, and the positions of the two sides had been exchanged, with Klee as the wingman and Vic as the lead.

The advantage of the two-plane formation is also here. Generally speaking, the long plane will attack, and the wingman will take the cover task. However, once the shooting angle is more suitable, the wingman will turn to attack, and the long plane will protect in turn.

This kind of combat is quite flexible and flexible.

As Vic turned into the climb, the flameout Spitfire could be seen 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 the engine with more than a dozen cylinders. Now, you can see that this Spitfire is constantly emitting black smoke. Only a few cylinders are successfully started, and the rest are always Can't start.

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

flood the tank.

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

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

In short, they can only move on the ground. Now, in the sky, when the engine is flooded, it will stop completely.

Vic is not such a gentleman, waiting for the opponent to launch a re-air battle. At this time, Vic has approached the opponent's nine o'clock direction, and the opponent's fuselage is perfectly displayed in Vic's field of vision.

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

"Tom tom tom!" The 20mm shaft gun has limited ammunition, so after Vic took aim, it was only a short shot and five shells were fired, and it hit the opponent's fuselage accurately!

"Boom!" The armor-piercing incendiary bomb directly hit the fuel tank behind the opponent, even with self-closing technology. The effect of the incendiary bomb made the rear fuselage of this fighter burn!

A shot down!

Vic won, and finally he is no longer a rookie. Only by shooting down enemy planes can he become a veteran!

"Quick, roll away!" At this moment, Klee's voice came from the radio.

Just as they shot down the Spitfire, the other two fighter jets in the Spitfire formation had already pounced hard.

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

Here, it is no longer on land, but at sea. Even if it is parachuting at sea, it is not easy to survive. Moreover, looking at the appearance of the wingman, I am afraid that there is no chance to even parachute.

"Da da da." 4 7.7mm machine guns, dense bullets flew towards Vic's fighter, it seems that Vic's fighter was surrounded by this barrage, but this Bf109, but calmly got rid of .

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

This is a lesson learned by the Luftwaffe when they fought over Spain. They often found themselves hitting their opponents, but could not shoot them down, because the machine guns were not powerful enough!

Therefore, they improved the cannon, which is still the easiest to aim.

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

Theoretically speaking, the performance of the Spitfire is not far behind. Although the cockpit is a little frustrating, the plane flies quite fluently, and the climb performance is even better, but now, they can't discuss it in front of the Germans to cheap!

When they catch up with the German fighter jets, the other party will get rid of them, they can't keep up, and sometimes they even have the opportunity to fire, at most, they will hurt the other party, but every attack of the other party can blow them up!
