Open an aircraft carrier to fight against Japan

The Russian army ran downstream and hit the gunboat in the arms. The gunboat adjusted its speed and went down the river. It called the Russian soldiers with machine guns. The terrified Russian soldiers ran away from the river bank desperately. , but can not go ashore!

The Russian soldiers made the wrong wishful thinking. The gunboats not only have artillery and machine guns, but also fifty heavily armed soldiers on each ship. There are [-] soldiers in sixteen gunboats. Chase the Russian soldiers.

Just when the battle situation was overwhelming, Zhang Yao in the city suddenly ordered his men to prepare their horses and leave the city!

The soldiers under his command asked: "There is no need to go out of the city to pursue the enemy, right? Our fleet is enough to deal with them."

Zhang Yao said, "I didn't leave the city to chase the enemy."

The soldiers under his command asked again, Zhang Yao had already rushed out with ten soldiers on fast horses, the horses they were riding were also taken from the Russians, these horses were very fast, so Zhang Yao had already taken Ten warriors left the city.

Zhang Yao's target was the Russian artillery. He guessed that the Russians probably used brand new artillery. The Russian army retreated and would not leave these four artillery pieces to himself, so he wanted to transfer them to the Russians. Before, take them back.

Zhang Yao led his men to rush towards the artillery position, and saw four huge monsters moving on the grass from a distance, and the speed was not too slow. Zhang Yao thought to himself: "The Russian heavy artillery did not sink into the ground. I don't know what was used on it. Brilliant trick."

Eight horses pulled four cannons and fled to the upper reaches of the river. The position of the Russian artillery was relatively remote, so the gunboat did not find them. If Zhang Yao hadn't arrived in time, they would have escaped. The gunners, seeing Zhang Yao chasing up, raised their rifles and shot at them.

Zhang Yao held a semi-automatic rifle produced by the Beijing warship in his hand, swung it left and right, and the ten fighters divided into left and right, and surrounded the cannon carriage. Well, if you chase from behind in a straight line, the gunner doesn't need to calculate the lead, and the fighter can easily be hit, but it's different if you outflank to the left and right. The gunner must consider the lead when shooting, and also correct the bump of the gun car , so the hit rate is greatly reduced.Zhang Yao ordered: "Kill the old man who is driving the cart first!" The soldiers under him have all been trained to shoot immediately, and their skills are extraordinary. Without human command, they stopped one after another. The remaining gunners got out of the car, leaned on the gun body, struggled to death, and were all shot dead soon.Zhang Yao leaned forward and took a closer look at the cannon. The caliber was indeed one size larger than the original 75mm cannon, and the biggest change was the wheels. The wheels were no longer wood wrapped in iron sheets, but thick rubber tires. , no wonder the four cannons did not sink into the ground.

In this battle, 480 and 540 Russian soldiers were killed, [-] and [-] surrendered, and the rest fled back to the camp near Wandashan Fortress in embarrassment.

What Lin Yuan was most interested in was the four cannons. When the flood receded, Lin Yuan left four gunboats in Lahasusu as cover, and the rest returned to Sanxing City with the four cannons.

Luo Chaoying had already taken the train from Tianjin Machinery Bureau to Sanxing City at this time. Lin Yuan's strategy was: Wherever the troops went, the railway would be repaired. Therefore, railway lines have been widely established in various parts of the Northeast. People's original railway, the railway in Northeast China already has considerable material transportation capacity.

Luo Chaoying first asked someone to bring a cannonball. He compared it with his hands and said, "The aspect ratio is close to the cannonballs of our era. It seems that the Russians have a good understanding of aerodynamic technology."

Luo Chaoying had the cannon disassembled. He took out the vernier caliper, measured between the two rifling lines of the muzzle for a while, and then said: "[-]mm, such a cannon is quite powerful! It seems that the Russian People's iron and steel smelting technology has reached a big level!"

Lin Yuan said: "Didn't you also plan to design and manufacture artillery of this caliber a while ago?"

Luo Chaoying kicked the rubber wheel and said: "If we had such a rubber tire at that time, wouldn't we have made it? Now the wheels are still made of wood and covered with iron sheets, and they are easy to sink into the mud. Not to mention, this kind of wheel can't absorb shocks and can't maneuver quickly."

Lin Yuan said: "Don't worry, we will be able to manufacture the rubber soon."

Luo Chaoying said: "That would be great. At that time, we could even manufacture a 150mm cannon howitzer, and its firepower would far exceed any artillery in the world today."

While talking, Luo Chaoying ordered people to remove the barrel of the artillery, then glanced at the connection between the barrel and the frame, and said with a smile: "With a spring-type retreating machine, the rate of fire will not be very fast. If we want to build a new artillery, we must use a hydraulic gas type retreating machine." Lin Yuan said: "Old Luo, what we need to design now is not a large military-level support artillery, but one that can provide firepower for individual soldiers. sent weapons."

Luo Chaoying was taken aback, and Lin Yuan explained: "Our next combat target is the Russian army in the mountains. The roads in the mountains are narrow, and it is inconvenient for large artillery to maneuver."

Luo Chaoying asked: "What weapons are you referring to that provide firepower projection for individual soldiers?"

Lin Yuan said: "Take the infantry equipment of our era as an example, such as the [-] bazooka."

Luo Chaoying said: "The range of these weapons is relatively short. For example, the 250 rocket launcher has a gauge distance of only 100 meters. In actual combat, it is rarely used beyond [-] meters." Lin Yuan said: "That doesn't matter, there are many mountain battles. It’s all about close quarters combat, and you don’t need a lot of range.”

Luo Chaoying said: "In our era, individual rocket launchers were mainly used for anti-tank use. Metal jet armor-piercing warheads were widely used in rockets. Since there are no tanks in this era, we can improve the warheads. But the most critical It is propellant, we make shells, propellant can be made of black powder, but rockets need to be propelled by solid fuel, and the propellant needs to be made into blocks, so black powder cannot be used for this, do you know what propellant should be used?"

Lin Yuan said: "I know that solid rocket propellant generally uses nitrocellulose and nitroglycerin." Luo Chaoying said: "Nitrocellulose can be produced by Tianjin Machinery Bureau. Although the output is not high, it is enough, but nitroglycerin, let's go Where can I find it?"

Lin Yuan smiled and said, "Why are you confused? Our petroleum industry has already started. Petroleum is simply a cornucopia for the chemical industry. Many chemical raw materials can be found there. Nitroglycerin is made from the reaction of glycerin and nitric acid. What is glycerin? Isn’t it just glycerin? We can use catalytic hydrogenation to produce glycerin, and we also have nitric acid. Isn’t it natural to produce nitroglycerin?”

Luo Chaoying said: "If you say this, I will go back and prepare. Soon we will be able to produce a batch of individual rockets."
