Because the rubber required for the steam engine cylinder has been solved, the design bureau decided to draw a blueprint for the manufacturing of the steam engine. The subtlety of the drawing is not the steam engine, but the crazily rotating gear powered by steam, and the "cut into pieces"
The perfect combination of gasoline engines!
In the past twenty years since the establishment of the Soviet Union, ten-year compulsory education has been promoted across the country. The Soviet education system is also unique in the world. That is, children who enter school will learn a lot of knowledge in ten years. When the children graduate from tenth grade, they should go to school.
College!
Poor Natasha, after finishing her last school year, she has the possibility of going to university. However, for a child from a remote area like her, the possibility of going to university is not high.
The battlefield gave her a unique possibility. Because of her great honor, this ninth-grade child was almost guaranteed to be admitted to Moscow University for further study after the war, or even to the Frunze Military Academy.
The most important thing for such children is the knowledge in their heads. By the seventh grade, children will learn physics knowledge in depth. They must understand the relationship between magnetism and electricity and electricity and magnetism. Most of the workers in the arsenal have completed their obligations.
Education, and this is also a huge advantage of the guerrilla republic!
The husband introduced the current work of the workers: "After installing all the components of the steam engine, it can be connected to the modified generator!"
Yang Mingzhi personally witnessed this momentous moment, and soon the docking work of the two machines actually began.
The steam engine with its parts installed was placed on a large base and fixed with a large number of bolts. Then, two workers held an exposed electric motor and placed it on the base.
Yang Mingzhi was amazed at all this. He asked: "I ignored the manufacturing of the base in the design drawing. You added the base. How do you ensure that the machine is stably fixed to the base by relying on these bolts?"
Speaking of the base, Liguschkov once again showed his merit: "Of course! Comrade Commander, our bolts are very strong, and the base is also made of special material! You can be sure to see that the reflection of the base is different!"
The light in the room was a little dim, so Yang Mingzhi simply took out the half-worn glasses from his pocket. He took a closer look and found that the reflection was indeed strange. What on earth is this? The color looks like aluminum!
Seeing the commander's surprised expression, Liguschkov got excited: "Our base is not carburized steel. Our blast furnace can already produce some higher-grade alloys. Of course, we also need unique raw materials for production. You
The base you are looking at is made of aluminum alloy!”
"Oops! Is it really aluminum?!"
"It is indeed aluminum alloy!"
"Why is aluminum now a hundred times more valuable than iron? Where does the aluminum used in arsenals come from?!"
"airplane!"
Liguschkov's answer was just one word, and that was enough! Yang Mingzhi slapped his thigh hard, and he suddenly thought that the fallen TB3 was full of treasures! The aluminum in these aluminum alloys all came from the TB3 bomber.
The skin is finally melted in a blast furnace, and other metals are added, turning it into a strong, light, and shiny aluminum alloy!
The Soviet Union's aviation materials are not lagging behind. As early as the 1920s, when the Soviet Union was founded, its domestically produced "Koli Qiugen Aluminum" was successfully produced. It was the widespread application of electrolytic aluminum technology and solved the problem of mass production of aluminum. With the Soviet Union located in
With the stable power supply of the Dnieper River hydropower station downstream of Kiev, the Soviet electrolytic aluminum industry is also on the right track.
By the 1930s, Soviet large transport aircraft and bombers were basically made of aluminum alloy and steel. For example, the wings of the TB3 bomber were all made of aluminum sheets.
When the war broke out, the German army occupied the entire Dnieper River Basin, which dealt a fatal blow to the Soviet aluminum industry and even the aviation materials industry!
Sixty percent of the Soviet Union's aviation aluminum materials require the supply of two aluminum plants in Dnepropetrovsk and Volkhov in Ukraine, and the electricity needs to be provided by the Dnieper Hydropower Station. The aluminum alloys that can be provided by factories in the Ural region
, only 5% of the country.
This was the situation at the beginning of the war.
When the war broke out, because the German army was advancing too fast, it was difficult to relocate a large number of heavy equipment from Soviet factories. They blew up some factories, and more were occupied by the German army. Even the Dnieper Hydropower Station! The German army had to achieve the goal of supporting the war.
For the purpose of the war, they used the Soviet Union's proven bauxite ore and the remaining electrolytic aluminum factories to mass-produce aluminum materials urgently needed by the German army.
The Soviet army lost these factories in Ukraine, and the losses were not small. However, talent is the key to everything. A large number of technical personnel strategically retreated, and the factories that had not been occupied by the German army were also lost during the Soviet counterattack in the first half of 1942.
, start the relocation.
New factories were established in the Ural region and Siberia. Cities along the Siberian Railway, such as Irkutsk, Torsk, and Novosibirsk, developed rapidly. The Soviet heavy industry was able to recover quickly in the rear. At the same time, the United States
Extremely large-scale strategic assistance under the Lend-Lease Act was also fully launched in early 1943.
What Liguschkov created was not just an aluminum alloy base. Yang Mingzhi noticed that some metal parts were also made of aluminum alloy.
Yang Mingzhi, who is very familiar with the metal industry, has no intention of criticizing him for this. Because, if he could think of using the aluminum alloy waste of the aircraft, many parts in the design drawings would simply be made of aluminum alloy! This is as a commander
It was his comfort. Since Liguschkov decisively used new materials, he didn’t need to say more.
Yang Mingzhi was interested in watching the further work of the workers, and saw that the steam engine and generator were quickly connected. After a few gears were connected, the machine was ready for operation.
The output voltage of this generator with its internal combustion engine removed is 220 volts direct current, which can supply most electrical appliances in the Soviet Union. The voltage guarantee of 220V depends entirely on the stable speed of the rotor. The structure of the generator was studied by people from the design bureau.
It is very thorough, so after changing the power to a steam engine, the rotor speed can be adjusted theoretically by several gears to ultimately ensure the stability of the electric power.
Of course, when the radar equipment starts working, the power of the magnetron is very huge! The modified steam generator also needs to convert the direct current into alternating current, and then use the transformer to boost the voltage again, so that the magnetron can work stably.
In this era, these devices are nothing more than silly, thick and crude things. Even if Yang Mingzhi is here, he cannot further simplify the equipment with the materials on hand. Even when all the equipment is completed, its overall volume is larger than what the Soviet Union currently has.
For huge!
Perhaps because Yang Mingzhi was watching here, the workers worked very quickly. After the generator connection was completed, Liguschkov said: "Theoretically, this machine already has the power supply capability. If the commander wants, we can do it now."
test."
"Experiment!"
The future of radar began with this generator, and Yang Mingzhi issued the test order.
Because this is a steam engine, you first have to boil a kettle of water. This is a relatively slow process. Yang Mingzhi always stood there waiting.
When the actual pressure on the pressure gauge reached the rated value, the workers opened the valve.
This is a fairly well-made small steam engine, but its principle is no different from that of the 18th century. It even has a sense of history as a whole. The difference from those steam engines in history is that the cylinder can carry stronger loads. Atmospheric pressure, therefore the theoretical output kilometers of the steam engine is as high as an astonishing figure of 500 horsepower. The cylinder drives the disk to rotate, and after the cooperation of several gears, it eventually turns into the crazy rotation of the generator rotor, desperately cutting the magnetic lines, thus generating electricity. .
When the crazy rotation of the generator brought out a unique peak sound, the workers involved in the manufacturing all let out a shout of victory.
A worker wearing overalls full of oil stains took a voltmeter to measure and got satisfactory results.
The voltage is close to 220 volts, which is 2 volts less than planned on the drawing. Overall, it's no big deal.
"A good start is half the battle! Next, you have to build the inverter."
"The inverter is already being produced." Liguschkov said with great pride. "With the commander's drawings, we can work very efficiently. The radar will be ready around June 15th."
This person said this casually. From Yang Mingzhi's point of view, how could he not be shocked!
"In other words, you can complete all the equipment in three days at the earliest?"
"Yes!"
"Very good, I think I should also prepare professional radar soldiers!"
