Open an aircraft carrier to fight against Japan

The mysterious colonel smiled, "I can't take care of what happens after it flies out, I can only take care of its inside the barrel."

At this moment, the communicator of the mysterious colonel rang, and the mysterious colonel pressed it casually, and only heard the communicator say: "Report to the captain, the launch preparations are complete, do you want to launch?"

The mysterious colonel said "launch", and the three of Long Xuhui only heard a violent "buzzing" sound from inside the mysterious tank, as if the mysterious tank had turned into a huge beehive with tens of millions of bees inside.

Suddenly, I only heard a loud "bang" coming from the muzzle, and I saw something flying out of the muzzle. Xuhui is very familiar with the sonic boom sound that occurs when objects exceed the speed of sound.

The muzzle velocity of the tk-99 main battle tank shell exceeds the speed of sound, so Long Xuhui and the others are no strangers to the sound of a sonic boom, and they are not surprised that the shell fired by this mysterious tank can exceed the speed of sound. Personally, I was surprised that this mysterious tank fired such a fast shell, but it didn't seem to suffer much recoil, and the body showed no sign of retreating at all.

The recoil of high-speed projectiles is very strong. When the tk-99 main battle tank fires projectiles in situ, the recoil force can make the entire body fall back two distances from the track shoes. The sonic boom is louder than The shells of the tk-99 main battle tank are much louder, obviously faster than the shells of the tk-99 main battle tank, but it does not have a rear seat.

Long Xuhui asked in a low voice: "Chief, why doesn't your tank take the back seat?"

"Hush..." The mysterious colonel made a quiet gesture, and Long Xuhui hurriedly said: "Report to the chief, don't ask what you shouldn't, I know I'm wrong."

The mysterious colonel smiled helplessly, "I want to wait until the shell hits the target before speaking."

"Can...can it hit?" All three of them were wondering. At this moment, they saw a faint light flashing in the direction of the German barracks. The light was like a match that was about to go out in the dark night.

Long Xuhui asked in surprise, "Is that the light from the shell explosion?"

The mysterious colonel laughed, "It's [-] kilometers away from here. How can the light of a shell explode [-] kilometers away?"

Long Xuhui asked hesitantly: "How did the light come out? Could it be that the shell hit the German tank and detonated the ammunition in the car?"

The mysterious colonel shrugged, "I don't know either, haha, we have to ask the observer." The mysterious colonel said, looking at the officer who was manipulating the telescope in the distance, "Observer, do you see clearly?"

"Reporting captain, you can see clearly, the shell we fired hit a German tank precisely, and the flame just now came from the explosion of that German tank."

The mysterious colonel turned his head to Long Xuhui and the three of them with a smile and said, "Our shell really hit the German tank."

The three of Long Xuhui were stunned and couldn't say a word. The mysterious colonel smiled and said, "Hey, what's wrong with you, are you stupid? Don't you want to know why it has no recoil. I'll tell you now."

The three of Long Xuhui came back to their senses and asked one after another: "Why doesn't it have recoil?

The mysterious colonel asked with a smile: "Do you know how recoil is generated?"

"Because the shell is propelled by gunpowder gas, when the gunpowder gas pushes the shell forward, it will also hit the gun body or the gun body backward. This impact is the source of the recoil." Chu Weicheng said hurriedly.

"Very good!" The mysterious colonel gave a thumbs up and then lowered his hand, "You are right, this is how the recoil force is generated, now please think about it, if the shell is not propelled by gunpowder gas, then the recoil force Will there be more?"

Long Xuhui shook his head lightly, "There shouldn't be any, right? But how could the shells not be pushed by the gunpowder gas?"

Chu Weicheng suddenly exclaimed: "Isn't the shell of this tank propelled by gunpowder gas? Then what is it propelled by?"

"Ah!" Long Xuhui screamed suddenly, causing the other three people to jump up in fright. The mysterious colonel asked in shock, "What's wrong with you? What are you screaming? Did you get hit by a shell?"

"Reporting chief, we know we are wrong, please, don't kill us, let us go to the battlefield and die with the Germans, please..." Long Xuhui chanted these words, as if going crazy, the mysterious colonel He smiled helplessly, "What kind of nonsense are you talking about?"

"Chief, your identity is very mysterious, and this weapon is also very mysterious, and the three of us are just ordinary commanders, gunners, and drivers. It stands to reason that we are not qualified to listen to such secrets. Now you want to There can only be one reason for telling us all these secrets, and that is that you want to kill us..." The more Long Xuhui spoke, the more desperate he became, and he almost knelt down to the mysterious colonel. Chu Weicheng and Zhou Minghan also had expressions on their faces. panic.

The mysterious colonel laughed out loud, pointing at Long Xuhui, and said, "You are so funny, I am so right to keep you by my side, with you, life is really much more fun, don't talk nonsense , I didn't intend to kill you."

"Then why are you telling us such a confidential matter?"

"Because this matter will soon be disclosed on a large scale, so weapons will be used on a large scale."

"Such a confidential matter is going to be made public?" The three of Long Xuhui couldn't believe it, and the mysterious colonel smiled, "Do you still want to listen to me say that there is no recoil-free secret?"

"Go ahead."

"The reason why our tank has no recoil is because there is no propellant in it, let alone gunpowder gas. Since there is no gunpowder gas, there can be no recoil. The thing we use to replace the propellant is— -electricity."

"Electricity? How can electricity replace propellants?"

"When you were training in the military camp, you should have learned about electromagnetic induction. Electricity can generate magnetism, and magnetism can also generate electricity. Electricity can drive objects to move. You all understand this."

"Yes, although we can't remember those long lists of formulas, we all understand these principles."

The mysterious colonel smiled and said, "It's good to understand. Our projectile is made of some kind of high-density material and weighs only one kilogram. Isn't it much lighter than your tank gun shell?"

The three of Long Xuhui nodded dumbly, and the mysterious colonel continued to laugh and said, "However, the velocity of your shells is less than 500 meters per second, while our projectiles are discharged at a velocity of 5000 meters per second."
