Yang Mingzhi knew very well that the magnetron in his hand was indeed the heart of the radar. To truly build a radar, a lot of equipment was needed. In addition to some necessary equipment, many seemingly insignificant parts had no bearing on the ability of the equipment.
Manufacturing is also crucial.
The so-called radar relies on this magnetron to emit high-frequency microwaves. When the microwaves hit an object and are reflected, they are detected by the receiving antenna. Although an oscilloscope does not exist, it is still possible to sense the returned information.
Therefore, Yang Mingzhi explained to all the staff of the design bureau: "Next, we will rely on this resonant cavity magnetron dismantled from the radar truck to manufacture our early warning radar. Except for this equipment, everything must be made from scratch.
To start. We don’t even have an oscilloscope, and eventually, through the continuous work of the monitor, we will sense the noise coming from the headphones to determine whether the noise indicates an enemy aircraft or a bird, and the direction in which it is coming.”
This is a very backward radar. It is so backward that even the most primitive oscilloscope does not exist. It is even more backward than the Japanese army's electric detection.
This is like a blind person who relies on the sound to perceive what is coming towards him. But when the blind person is skilled enough, he can judge through the sound that the coming person is a puppy or a pedestrian!
For the Soviet Army in the swamp, only in autumn and winter did migratory birds come to the swamp to spend the winter. Eagles occasionally flew over this sky, and other larger flying objects were airplanes. In this way, Yang Mingzhi estimated
Well, as long as the radar is put into use and the listener hears noise from a certain direction, he can basically determine that it is an airplane!
His explanation convinced many designers, and they quickly hit a wall in the subsequent design.
Yang Mingzhi soon encountered a very tearful situation, because most of these outstanding scientific and technical personnel still knew very little about radar technology!
As the main planner of this project, Yang Mingzhi put aside many things without hesitation and insisted on doing the work himself in the large office of the design bureau. At the same time, he also had no choice but to act as a teacher, starting from the details, teaching these young designers
Explain the principles of radar.
The research and development work lasted four days, and it was not until June 5 that the basic blueprint was finally summarized.
This is an early warning radar that is quite advanced even in this era.
The peak operating power is 100 kilowatts, working in the 400 to 500 MHz band, and can detect flying objects 70 kilometers away and 1,000 to 3,500 meters away.
According to the analysis after the air strike, the German airport may be near Lechica or Gomel. Therefore, after the radar was manufactured, the radar station was placed in the ruins of Homnich. Once the enemy plane takes off, it can be discovered immediately.
Furthermore, as for the German fighter jets and dive bombers, they have no reason to fly too high. About three thousand meters is the optimal altitude.
Currently, this radar equipment, which has no name, only exists on dozens of pieces of kraft paper. It seems that as long as the arsenal follows the drawings, the radar will be really built.
Of course the problem is not that simple.
The biggest problem now is no longer the magnetron, but where does the energy to emit powerful microwaves come from?
Use a generator? This consumes precious fuel. The army's fuel reserves are not large, and it cannot withstand the consumption of radar! Unless the radar is only intermittent, but in that case, the significance of radar warning will not exist.
Finally, an idea from a year ago came back to me.
"There is no other way! To supply energy to the radar stably, we can only disassemble a generator and build a steam engine. Let the steam engine drive the generator rotor and always supply energy to the radar!"
No one questioned Yang Mingzhi's decision, and he finally reached a field that everyone fully understood. The manufacturing drawings of the steam engine were quickly drawn up.
They made drawings of steam engines and large radar antennas.
In his plan, a radio station will be transformed as a receiving terminal, and its drawings have also been drawn.
Yang Mingzhi was praised by the American media for his transformation of the radio station. Although he could not get an oscilloscope, he could still get a lot of components by dismantling the radio station, such as luminous tubes. The antenna received the radar echo, and the equipment made the tubes glow.
The monitor can see the anomaly and further hear a loud noise in the headphones that far exceeds the ambient noise.
In the final analysis, as long as the feedback received by this device after detecting a flying object can be transformed into information that humans can understand, it is enough!
…
Yang Mingzhi is strong, and his comrades believe that he is a wise man like steel, a true fighting hero, and a hero who is invincible.
However, the overloaded work that lasted for several days was taxing his body, and the bad weather also caused the temperature to continue to drop. His iron-like body would also rust under the continuous rain, and Yang Mingzhi caught a cold.
Sick? The last time you caught a cold was in winter. It doesn't matter if you take some medicine!
Therefore, when his throat began to feel uncomfortable, he drank more hot water, and then continued to devote himself to radar research and development day and night. He gradually began to cough, and his body became softer and softer.
In fact, since returning from the headquarters on June 4, he has stayed in the office of the Weapons Design Bureau and launched the final attack here.
"I just have a common cold. Our main task at the moment is to complete all the drawings as soon as possible and hand them over to the arsenal. As for my body, after finishing these work, I will go to the hospital and inject some sulfonamide!"
He was the commander of the group army, and the leader and others did not dare to disobey orders. Furthermore, the officer looked very good. If he just coughed, it would not affect anything.
Undoubtedly, this is the negligence of all colleagues in the design bureau, as well as Yang Mingzhi's own negligence.
The work lasted until one o'clock in the morning on June 6, when all the drawings were declared completed. In terms of scientific research, Yang Mingzhi regarded himself very highly. He never thought that Liguschkov in the arsenal had greater abilities, so the drawings must be drawn carefully.
, all process steps must be clearly written. He supervised the entire process and personally reviewed the drawings at the end.
His mind is the best computer, and his mind is the final form of this radar device.
In his plan, this early warning radar manufactured by the Guerrilla Republic was as sophisticated and advanced as possible because the radar was mobile.
For this purpose, the army will modify two trucks. One will install the main body of the radar equipment on its open compartment, and the other will install a generator and steam engine as the energy source for the radar. The two trucks will operate at the same time and will be completed after arriving at the predetermined location.
The circuit is connected and a long-term air scan begins.
Because this bulky radar car is powered by a steam engine, it naturally burns peat. This is the worst coal containing a huge amount of impurities, and the thick black smoke it burns has always worried Yang Mingzhi. However, if the equipment can really achieve
The design requires that enemy planes can be detected 70 kilometers away, so it doesn't matter if there is smoke. Especially if the car is driven to Homnich, it can even monitor the entire airspace from Mozyr to Gomel!
Yang Mingzhi was full of confidence in the future of radar. At dawn, he personally took the drawings to the arsenal and ordered them to complete the finished product in the shortest possible time!
In his excitement, he also ignored his body. When he woke up again, he finally felt the weight of his body, as if he was in the deep sea. Moreover, what a wonderful figure he saw with his hazy eyes.
