Open an aircraft carrier to fight against Japan

Seeing Luo Chaoying's expression, Lin Yuan quickly asked, "What's wrong with you? Is there something wrong?"

Luo Chaoying said: "The caliber of this shell has reached 150 mm, but that's nothing. Look at the length of this shell. It's a full 50 mm, and the bomb-to-diameter ratio has exceeded three. This number has caught up to two." The development level of the grenade in the [-]s has improved, and it seems that the Russian technology has made a lot of progress!"

Just as Lin Yuan wanted to ask if he could determine the range of the cannonball, Luo Chaoying already moved his head close to the cannonball. He looked at the cannonball carefully, and then said, "I have to see what they put in the cannonball?"

Luo Chaoying said, called a few assistants over, and said, "Go and get the tools, let's take this shell apart."

Several assistants quickly brought wrenches and other tools. Luo Chaoying pointed to a position of the warhead and said: "The Russian shells are divided into two parts, and the head and the middle and rear parts are connected by threads. This connection method It's out of sight now, and we're taking it apart."

Lin Yuan quickly said, "Is there any danger?"

Luo Chaoying said with a smile: "Don't worry, nothing will happen. The explosive inside must be very stable. If it explodes as soon as it is touched, no one would dare to use it to load shells."

When several people took apart the shell, the dense light yellow explosive inside was exposed. Luo Chaoying looked at it carefully, then slapped it lightly with his hand, sniffed the smell of the explosive, and said in surprise: " The Russians have started using tnt for explosives!"

Lin Yuan knew that TNT was widely used in wars during the First World War. The development of explosive technology was also an important part of the development of military technology. The improvement of explosives played a decisive role in improving the power of weapons and equipment, but , Lin Yuan was more worried about deeper matters.

The Russians improved the shape of the projectile, which seems to be only a small change, and behind this is a further mastery and understanding of aerodynamics. It is hard to imagine that without a solid aerodynamic foundation, they could design a projectile with a length of three Double-caliber shells can design a ship-shaped tail. If they have a deeper grasp of aerodynamics, will they develop an aircraft based on this?

Lin Yuan was thinking about it, Luo Chaoying asked, "What are you thinking about?"

Lin Yuan didn't tell Luo Chaoying what he was thinking, but asked: "Old Luo, the artillery of the Russian army is very accurate and caused a lot of damage to our troops. I want to blow them up, but I can't." To determine their positions, can you find some clues from the shells to deduce the range of the shells, so that I can deduce the position of the enemy's artillery from the range." Luo Chaoying thought for a while and said: "There is a way, but the accuracy is poor some."

Lin Yuan said: "As long as there is distance, I will find a way for the rest."

Luo Chaoying said to an assistant: "Bring our magnifying glass." The assistant quickly took a magnifying glass and put it in Luo Chaoying's hand. He knocked on the belt and said: "Look, this belt is made of copper, and there are indentations on it caused by friction with the rifling in the barrel."

Lin Yuan took the magnifying glass, looked at it, and asked, "What can you tell from this?"

Luo Chaoying said with a smile: "According to the wear of the belt, we can see the rotational speed of the shell moving in the barrel. There is a certain relationship between the rotational speed and the initial velocity of the muzzle. We can determine the initial velocity according to the rotational speed, and then use this initial velocity to roughly Estimate the range of the shell."

"However, the result obtained by doing this is very inaccurate, because we don't know the angle at which the shell was fired, and the air environment is also greatly affected, so I say there will be a lot of error."

Lin Yuan nodded and said, "Then please calculate a range for me, and I will make a choice based on this range."

When Lin Yuan came back from Luo Chaoying, he was about to get aerial pictures of the ten kilometers in depth opposite the position. In these pictures, there were many open spaces with barracks. Lin Yuan knew that those places were Russian barracks, but due to the The heavy snow covered everything in the barracks, so Lin Yuan couldn't know which places were artillery positions.

At midnight, Luo Chaoying sent over the possible range results. The range ranged from 1000 meters to 7000 meters. Lin Yuan compared the Russian barracks on the aerial map. There were nineteen in this range. Yuan was very helpless. There were too many barracks, and it was impossible to determine the position of the artillery positions.

Lin Yuan reluctantly put the pictures aside. It seemed that his method had failed, and it was impossible to know the location of the artillery position with this method.Lin Yuan suddenly felt flustered. He couldn't help but think of the scene when he flew a fighter plane for the first time. When the plane rose into the sky, his mind seemed to be blank, and he completely forgot about the subjects to fly. Finally, it landed after turning around in the sky.

Lin Yuan went outside the tent and looked at the starry sky in the winter night. The dots of stars were like the eyes of the night. Lin Yuan could not help but think: After tomorrow, if there are still shells from the Russian army falling on our position, he will be breaking his promise At that time, the morale of the soldiers and civilians in the city will undoubtedly be greatly frustrated!

Lin Yuan thought to himself mockingly: "This time I came here to find out if the Russians used radios? I don't care about that now..." Suddenly, the words 'eyes' and 'radio' popped up In Lin Yuan's mind, there seemed to be a light of hope flashing in the dark night.

Lin Yuan thought: "When the artillerymen calibrate their shooting, if they use radios, isn't the radio the eyes of the artillerymen? As long as you find the position of the enemy's eyes, don't you know the enemy's position?"

Thinking of this, Lin Yuan immediately picked up the communicator and ordered the Beijing ship: "Immediately take off a J-25, carry an electronic reconnaissance pod, and check the area where I am, whether there are unknown electromagnetic wave signals."

After Lin Yuan gave the order, he paced anxiously outside the headquarters. Half an hour later, Xu Feng drove a J-25 to the vicinity of Qiqihar. He quickly contacted Lin Yuan and said, "I have arrived nearby. Airspace, signal search in progress."

Lin Yuan then began to wait anxiously, and after another half an hour, Xu Feng said: "There are no unknown electromagnetic signals around here!" Didn’t the Russians use radios? Did their scouts use telephones to correct shots for artillery units?”

Lin Yuan frowned, searching for the radio signal of the Russian army was his last hope. Could this not work?Lin Yuan suddenly thought of one thing, that is, he did not hear the explosion of Russian artillery shells throughout the night!Lin Yuan suddenly understood that in the dark night, the scouts could not see the target clearly, so there was no need to correct the shooting for the artillery.

Lin Yuan thought excitedly: "As long as we make a big commotion in the position, the scouts of the Russian army will think that we are going to attack, so they will let their artillery shoot!" Thinking of this, Lin Yuan hurriedly called He Lizhi , Said: "You order the troops quickly, light a bonfire on the position, create momentum, let the Russian army think that you are about to attack!"
