In the propeller era, aircraft engines were gasoline engines, high speed, high horsepower, but did not need much torque, on the ground, diesel engines were king.

The gasoline engine needs to mix gasoline and air and suck it into the cylinder, and this mixing process needs a carburetor to achieve it, so that the gasoline is evenly distributed into the air, and the cylinder is sucked into the mixture.

And this carburetor is realized under the action of gravity, that is, it can only be used upright, not backwards, and when it is reversed, it does not work.

From the point of view of acceleration, it must not fall into a negative G state, otherwise, the carburetor will stop working, the engine will lose oil, and it will stop running!

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

German planes, why not be afraid?

In the late thirties, Germany has realized direct fuel injection in aircraft engines, eliminated carburetors, and naturally does not have to worry about negative G oil cut-off!

(For comparison, in terms of automobiles, China almost in the nineties began to phase out carburetor engines and use EFI technology.) ）

This type of jetting does not need to be affected by gravity, so the plane can be in any state, as long as it does not disintegrate, there is no problem!

The current Spitfire has not yet realized this problem, and the British will not solve this main problem affecting air warfare until later improvements, and likewise eliminate carburetors.

But now, in front of the Spitfire, as long as the BF109 can perform a negative G maneuver, it can get rid of the other party, if the other party does not follow, then it can only watch the prey escape, if it does, it is the engine oil failure.

The Spitfire wingman, on the wrong hand, made an absolutely wrong move, the engine stopped, and the propeller in front of it did not move.

If it is in the usual training, the engine suddenly loses oil, 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 also be used as a glider and landed.

Although the technology of the aircraft has made great progress, after all, it is still the era of propeller aircraft, and the take-off and landing distances are short, as long as there is a flat land, he can land.

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

When he finished this action, Vic only felt the blood surge, and his eyes were about to turn red, but, thanks to his youth and excellent physical fitness, he quickly recovered, and when he continued to look backwards, he saw a Spitfire chasing him, which was falling down.

This is certainly a good opportunity! He immediately shouted over the radio, "Klee, there's a fat sheep coming with you, I'm going to go up!" ”

With that, he pushed the lever, rolled at a large angle, and climbed upward.

At this time, Klee in front of him also followed the operating stick, and the positions of the two sides have been reversed, Klee is the wingman, and Vic is the long machine.

The advantage of the two-plane formation is also this, generally speaking, the long plane is to attack, and the wingman is responsible for the covering task, but once the firing angle is more suitable, the wingman will switch to the attack, and the long plane will protect in turn.

This kind of combat is quite resilient and flexible.

When Vic turned to climb, he could see the flamethrower, which had been extinguished, struggling to start.

On the ground, with the help of ground staff, and in the air, it's completely on your own.

It is not so easy to start the engine of a dozen cylinders, and now, you can see that the Spitfire is constantly emitting black smoke, only a few cylinders are successfully started, and the rest are always unable to start.

The mechanical carburetor continues to release gasoline mixtures inward, and when the internal concentration is too high and is not activated, another terrible phenomenon occurs.

Flooded 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, it has to be on the ground to move, and now, in the sky, when the engine floods the cylinder, it will be completely stopped.

Vic will not be such a gentleman, waiting for the other party to launch a new air battle, at this time, Vic has approached the direction of the other party at nine o'clock, and the opponent's fuselage is perfectly displayed in Vic's field of vision.

At this time, the pilot of the wingman also noticed Vic, and he pushed the lever to avoid Vic's attack, but unfortunately, the plane that lost power had no maneuverability at all!

"Tom tom!" The 20 mm shaft gun had a limited reserve of ammunition, so after Vic aimed, he fired five shells in just a short shot, and accurately hit the opponent's fuselage!

"Boom!" The armor-piercing incendiary bomb directly hit the fuel tank behind the opponent, even if there is a self-closing technology, the effect attached to the incendiary bomb makes the rear fuselage of this fighter burn!

One Shot Down Result!

Vic is victorious, and finally he is no longer a rookie, and only by shooting down enemy planes can he become an old bird!

"Quick, get out of here!" Just then, Klee's voice came over the radio.

At the same time as they shot down the Spitfire, the other two fighters of the Spitfire formation had already pounced fiercely.

Henry's eyes were on fire, and he was quite furious as he watched his wingman be shot down.

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

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

In air combat, although the machine gun has a fast rate of fire and many bullets, the power of the bullets is not enough, so if you want to shoot down the opponent, you must go to the aircraft gun, and the caliber must exceed 20 mm!

This was the lesson learned by the Luftwaffe when they were fighting in the skies over Spain, and they often found themselves hitting their opponents, but they couldn't shoot them down, just because the machine guns were not powerful enough!

That's why they improved the aerial gun, which is still the easiest to aim at.

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

Theoretically speaking, the performance of the Spitfire is not lagging behind, although the cockpit is a little flustered, but the plane flies, it is still quite fluent, and the climbing performance is even more first-class, but now, they can't bargain in front of the Germans!

When they catch up with the German fighters, the other side will get rid of it, they can't keep up, and sometimes they even have the opportunity to open fire, at most they will damage the other side, but every attack of the other side can blow them up!
