Chapter 707: It's Better to Be a Warlord (4)

Early the next morning, in the presence of Kang Ze, commander of the Nanchang Xingying Special Brigade, the officers and men of the 1st Division's Special Service Regiment took the Red Army cadres rescued during the training operation to the edge of the Ganjiang River and dismissed all of them, and then returned to the Wuxi garrison. Pen? Interesting? Pavilion wWw. ｂiquge。 Although Kang Ze had the intention to stop it, seeing An Yi's cold gaze and feeling the solemn atmosphere in the air, he finally endured it and did not speak, and began to think about how to use this matter to behave well in front of the chairman.

Seeing Dongzi and Xu Yifan's car disappear at the end of the road, An Yicai said goodbye to Kang Ze with a smile, and returned to the guest house of the old Nanchang Jiangnan Hospital with Shen Fengdao, and picked up Han Yu's sisters and brothers to visit the old Nanchang.

After a night's rest, Han Yu and the three boys' spirits were obviously much better, and Han Yu's gaze at An Yi was a little less chilly and a little more warm.

Shen Fengdao drove the car, and the three boys sat in the passenger seat, looking at the bustling streets curiously, and exclaimed "tsk" from time to time.

An Yi sat in the back seat, introduced to Han Yu the origin of each street in Lao Nanchang, as well as some interesting stories about the shops he was familiar with from options, preparation to opening, explaining what these bosses used to do, how many people were employed after the business, how many taxes were provided for the government, and when he encountered a familiar shop opened by a disabled veteran, he would also ask Shen Fengdao to stop the car and take Han Yu and the three boys to go shopping.

At noon, it was still a meal in the old Han Tou's restaurant, and I originally planned to go to Jiangnan Hospital in the afternoon to visit the officers and soldiers of the 16th and 44th Divisions who were diverted here for treatment, to comfort the medical personnel working on the front line, and then to go to a few factories to take a look, so that Han Yu and the brothers could really feel what it means to truly love the country and serve the country, and what kind of life the people need, but two sudden good news disrupted An Yi's schedule:

The radar project team of the Institute of Electronic Applications of the Institute of Physics in Syria has successfully developed the first radar that can be used in practice, and the Southwest Agricultural College in Luzhou has cultivated hybrid rice.

Hybrid rice can greatly increase rice yields and save people from famine, and its benefits are needless to say, but An Yi now attaches the most importance to the invention and application of radar.

Due to his personal experience in the Songhu battlefield, An Yi hated the rampant and unscrupulous Japanese aircraft, and his thirst for radar was stronger than ever, so he decided to fly directly to Syria in the afternoon to send Han Yu's sisters and brothers to study, and at the same time learn about the development and mass production of radar.

At five o'clock in the afternoon, the plane slowly landed at the Minjiang Airport in Syria, and Yang Bin, commander of the southern Sichuan garrison, and Yin Jinan, commander of the 24th Army, personally went to the airport to greet them.

As soon as the Han Yu sisters jumped off the plane, they ran to the side and vomited, due to the air currents encountered during the flight, the sisters and brothers who took the plane for the first time no longer had the joy and curiosity when they first boarded the plane, and they were tossed to the ground, and now they are down-to-earth, and finally can't help but vomit.

An Yi whispered to Yin Jinan and others about the situation of the Han Yu sisters, and when they learned that Xu Jishen and other Huangpu brothers had been purged and passed away from within the Soviet District, Yin Jinan and Yang Bin sighed and felt sad, but they were helpless.

An Yi inquired about the situation of the troops, and learned that after the 16th and 44th divisions returned to their garrisons in southern Sichuan, they had now been replenished and were being summarized and trained, and An Yi couldn't help but breathe a sigh of relief. Yang Bin briefly introduced the development of the southern Sichuan region in the past four or five months, as well as the construction of the garrison and the production of military enterprises.

An Yi smiled, beckoned everyone to get in the car, and sent Han Yu's sister and brother to the hotel to settle down first.

In the evening of the same day, the laboratory of the Electronic Application Branch of the Institute of Physics, which is connected by an excavated passage at the top of Cuiping Mountain and the belly of the mountain, was brightly lit. Ochhumnovsky and the American electrologist Tiger Brown. George, Keno. Kuhn enthusiastically introduced the previous tests and the successful radar of this experiment to An Yi and his entourage.

Radar is based on the principle of bat "echolocation", the use of micro-segment electromagnetic waves to detect the target of electronic equipment, specifically the transmitter through the antenna electromagnetic wave energy to a certain direction of space, in this direction of the object reflects the electromagnetic waves, the antenna receives the reflected wave, sent to the receiving equipment for processing, extraction of certain information about the object.

The principles and theories seem simple, but it is difficult to manufacture the relevant machinery and apply it accurately. Tesla. Thirty-two years ago, Ochumnovsky came up with the concept of "radar" when he wrote in a magazine: "When we shout and hear an echo, we know that the sound must be reflected by a wall or other object...... The same should be true for radio waves...... We can thus determine the position, speed and ...... of objects (such as ships)" However, due to the frequent revolutions in Russia and the shortage of research funds, his research ended without a hitch, and after the October Revolution, he, like many Belarusian scholars, fled to China in a panic, and later went to Shanghai, where he was hired as a professor in the Department of Physics of Jiangnan University of Technology twenty-eight years later. After life settled down, Tesla began to study radar again.

When An Yi met and learned about his research subject, he was overjoyed and immediately appointed him as the person in charge of the radar project, asking for money and people to give people, and making every effort to develop radar.

At this time, after nearly 30 years of development, many research papers and related experimental reports on radar have been published in the world. In 1904, the German inventor Christian . Hulsmeier experimented with the original radar in the laboratory and patented the radar design, but the original radar detection range was not yet up to the distance of the acoustic locator. In 1922, Marconi, the "father of radio", predicted that the ability to use the characteristics of radio waves to reflect back when they encounter obstacles could be used to design an instrument to detect the presence and orientation of ships at long distances. Based on this, he drew a blueprint for the design of applied radar, which he also named "electromagnetic wave azimuth detector". In September of the same year, U.S. Navy experimenter Taylor . George and his assistant Younger were on the banks of the Portmac River near Washington, D.C., conducting cross-strait radio communication experiments. During the experiment, they found that whenever a ship passed through the area, there would be an unusual noise in the headphones, sometimes even causing communication to be interrupted. After analysis, they believed that it was the ship that hindered the propagation of electromagnetic waves. This is known as the "Portmark test". The test results show that when radio waves encounter metal objects, they can reflect like light.

Tesla. Ochu contempt, searched all over the United States, and a month later, found Taylor, who had not received a salary for half a year, in an electronics laboratory that was on the verge of bankruptcy. George and his lab partner Keno. Kuhn.

It turned out that Taylor. After the "Portmark Experiment", George decided to develop a machine that could detect targets by emitting and receiving reflections of radio waves, and began to develop a radar that could be used in the real world. So after retiring from the army, he joined an electronics company and began to apply for radar research projects, and everything went smoothly and smoothly, but the outbreak of the economic crisis disrupted their research, and everything came to a standstill.

After receiving an invitation from China, Taylor, who had already exhausted his family and was waiting to be fed. George and Keno. Without any hesitation, Kuhn took his wife and children, young and old, across the ocean, and his family to Nanchang, China, and then moved to southern Sichuan, a newly reclaimed hot land.

In an experiment conducted in January of this year, Tesla and Taylor. George, Keno. Kuhn was assembling a prototype radar and was debugging the instrument when he noticed a series of bright spots in the images on the instrument's phosphor screen. Where do these highlights come from? Is it because the camera has been working for too long and is malfunctioning? The assistants hurriedly turned on the imaging device and inspected several major parts, and it turned out that the device was working properly. Is that a disturbing effect on the surrounding electrical appliances? Everyone turned off the power of all electrical equipment in the vicinity, but the strange bright spot remained.

At this time, Tesla looked around and didn't see anything unusual. He turned his head to look out of the window of the laboratory, saw the mountain not far in front of the window, and wondered if it was blocking the path of electromagnetic waves. In order to verify his idea, Tesla instructed everyone to move the instrument to the top of the mountain, then plug it in, and everything was operated according to the original method, and the bright spots on the fluorescent screen were really gone. All the experimenters cheered with joy, which meant that the instrument they had worked so hard to develop had finally succeeded, because it was able to pick up the radio echo signal reflected back from the obstacle.

More than two months have passed in the blink of an eye, and this morning, the research team loaded the finished device on a truck for testing. The test aircraft flew from 15 kilometers away towards the location of the truck. When the aircraft came within 12 kilometers of the truck, the device successfully received the echo signal.

The first radar was born today, and the laboratory sent a good news to An Yi as soon as possible! The working principle of this radar is that the transmitter continuously emits radio waves into the air, and the radio waves will be reflected back when they encounter obstacles while moving forward, and they will be received through the antenna and displayed on a screen similar to a television.

After listening to the development process of the radar, An Yi was very moved, and immediately grabbed Tesla's hand: "Thank you, Mr. Tesla, thank you Taylor and Mr. Keno, you helped us solve the big trouble." In the battle with the aggressors last month, the officers and men of our army suffered so much from the enemy planes that they were unable to return fire, but now with the radar as a sharp weapon, the safety of our soldiers is guaranteed, and they are more confident in future wars! ”

Yang Bin and Yin Jinan didn't know much about radar at the beginning, and they didn't understand what benefits these expensive laboratories in the belly of Cuiping Mountain would be beneficial to future operations and economic development, but through Tesla's in-depth explanation, they immediately understood the huge deterrence of radar on aircraft and the impact on the future war, and immediately felt sincere admiration for An Yi's foresight.

Tesla smiled and shook his head: "Actually, I should thank you, you have made us who have been engaged in scientific research all our lives a place to use, let the flower of science sprout and grow again in our withered hearts, and let all our White Russians live and work in peace and contentment, free from the threat of hunger and wandering, there is nothing more touching than this." ”

Taylor. George also smiled and said: "Ann, if it weren't for you in the past two years, we would have joined the vast army of unemployed, received meager government relief, and lived starvingly. We are happy with where we are now. ”

Gino. Kuhn is excited: "The radar design we have made is very simple, it just needs to be produced by a specialist electronics factory, then assembled, and it will be ready for mass production in no time." ”

Tesla was a little disapproving: "The detection range of this radar is still too close, the distance of more than ten kilometers is not enough to change anything, the actual application value is not great, and we have to study and adjust and improve and expand the detection range." If the detection range can be expanded to 100 kilometers or even 500 kilometers, it will be different, and the fate of an air battle can be completely decided. ”

An Yi encouraged: "A journey of a thousand miles begins with a single step, and now that the most basic principles and applications have been realized, and the direction of research has been established, I believe that according to your strength, a breakthrough will definitely be achieved soon!" ”

Taylor. George thought for a while, and suddenly said to An Yi: "An, if the radar is equipped with the electronic computer developed by the research institute next door, it will be even more powerful!" Not only can we accurately predict the flight trajectory of enemy planes through careful calculations, but we can even make preparations for shooting in advance through computers, so that enemy planes can come and destroy one by one. ”

An Yi asked in surprise: "Mr. George, has the computer team developed a successful computer sample?" Why didn't I get the news of success? ”

Taylor. George said with some shame, "They haven't met your requirements yet, so they're embarrassed to report it to you." As far as I know, the current huge machine can only calculate more than 5,000 times per second, but it consumes tens of thousands of tubes, resistors, capacitors, and switches, plus dozens of air conditioners that run all day, and the electricity consumed is not a small number. I think most of the electricity generated by the thermal power plant on the bank of the Jinsha River at the foot of the mountain was consumed by them! ”

An Yi is very interested: "Every progress in electronic technology starts with the smallest accumulation. Now that they can carry out preliminary calculations, it means that their research direction is correct, and they only need to work on this basis in the future. Let's go and see, the first computer in human history, it's exciting to think about! ”
