In September 1921, the advent of transistors allowed the Institute of Electronics to shrink the radar to a size large enough to fit on a ship, and its stability was much better.

Radar is still being miniaturized and improved, Zhang Chun wants to hit this thing on the rocket, use it to navigate, attack aircraft or ships, the flight control station has been studying the rocket flight control for several years, originally thought that the rocket flight control is just to increase the range, now it seems that it is not, with radar, the rocket is no longer a rocket, theoretically, it can follow the radar to guide the attack. The flight control institute began to develop this rocket called the "Bat". Because it has a guiding function, Zhang Chun called this rocket a missile.

The missile, unlike an airplane, is very fast. Close to the speed of sound. So ordinary aircraft and ships are simply a target under such weapons. The only thing to consider is the stability of the electronic system, under the condition of high speed and high temperature, the stability of the electronic board developed by the electronics is very poor. Tests at Long Lake were not a single success.

Qin Deming, who had just won a science award for the invention of the transistor, was disgraced. The people in the electronics institute of the Green Lake Research Institute from production to research and development to theoretical research were driven crazy by him. But thanks to the establishment of the radar and missile programs, Xu Zhenpeng is already looking for ways to move these two things to his Xinjiang defense ship.

The first river defense ship was named "Long Lake". Rocket launchers were installed.

This device is a scaled-down version of the Goddess system. The biggest difference between it and the on-board system is that it has an automatic loading system, and the disadvantage is that it needs to be operated by a person in the operating compartment. The launcher rotates flexibly, the problem is to be attacked. It is difficult for the operator to escape.

In fact, the "Long Lake" is known for its speed, agility and firepower, and it is very crispy. But if the long-range missiles are successful, the Long Lake has absolutely no time to escape the enemy's attack.

In order to obtain a longer firing range on a smaller projectile body. The Ammunition Institute has been working on the principle of detonation and trying to make better fuel and better rocket engines.

The size of the goddess rocket is constantly shrinking. The firing range is constantly increasing. This rendered the original sighting system useless. The flight controller studies the laws of ballistics, when the electronic control system and the hydraulic system are combined. The flight controller tried to make the rocket run on a fixed trajectory. In this way, when the enemy's coordinates are calculated, it is only necessary to determine the initial bearing, angle and velocity. will be able to hit the enemy more accurately.

And this is exactly the effect that Xu Zhenpeng wants.

Transistors also make the troops' radio transmitting and receiving devices smaller. Individual soldiers can easily carry it on their backs.

So the radio is ready to be equipped to the platoon level. This is more suitable for the tactical habits of the Fourth Army. Because the Fourth Army has very high requirements for cooperation at the company and platoon levels.

It's just that the anti-interference and communication performance of the radio in the forest environment has been greatly affected. Several platoons of the experiment did not like it very much. They still like to use gestures to convey information between people. And they also dislike the sound of the call and expose their target.

The Institute of Electronics had no choice but to set up a special communication research institute to solve these problems. Is it just the amplification and restoration of the sound signal, making the speaker smaller, can it be placed in the ear? There's nothing you can't figure out.

Small. Smaller. Delicate, more sophisticated. It's something that all institutes are madly pursuing.

Equally crazy is the aircraft factory in Jingmen, where the Shuanghe smelter has finally produced aluminum and enough titanium. The people at the Aviation Power Institute finally have a high-temperature resistant and lightweight engine material. The Qianjiang refinery separated the light oil used in the engine, so the aircraft engine of the power plant carried out thrust experiments again, and it is said that there are still problems, but at least there is a direction to solve them. They've been on this path for almost a decade.

The flight control institute has long been designing the shape of the aircraft according to the principle of aerodynamic layout design envisioned by Zhang Chun. And on the basis of the rocket flight control system, the aircraft flight control system was developed.

In order to meet the needs of the aircraft factory, Kwong Rongguang extended the prospecting area to Yicheng, Zhongxiang and Jingshan, which he believed was a mining belt and there were opportunities to discover aluminum ore.

The people of the Fairy Industrial City began to enter the aluminum mine in batches. Because aluminum is very light. It couldn't be better than to make an airplane body out of it. It can also make train bodies and reduce the weight of trains. Plastics can also do this, but the chemical plants in Qianjiang do not produce enough plastics.

The stalls of the Wangchang Chemical Institute were spread too large and became the largest number of people. However, it is not possible to concentrate on assaulting units of a certain project. Mr. and Mrs. Wang Zili are not in a hurry, they said. Look, our foundation has been laid, and the results will definitely surpass you in the future.

The petrochemical industry is originally a huge system, and Qianjiang, oil is not the largest mineral, salt is. Therefore, the stall of salt chemical industry has also been rolled out. They don't want to just produce salt.

The scientific and technological strength of the Institute of Chemical Industry is very good, there are three professor-level figures alone, Zhang Chun is still more optimistic about them, the pollution of the chemical industry has always been a problem, and the Institute of Chemical Industry has spent a lot of time on dealing with pollution and establishing a complete industrial chain, so it is understandable that the progress is slow.

Oil and salt in Qianjiang. To a certain extent, it replaced the previous coal-fired oil plant, because that was too complicated. Coal production has been reduced again, and plant-based oil mills have cancelled some projects to concentrate on the research and manufacture of daily chemicals.

Since the output of the vegetable oil mill is very stable every year, there are no concerns about depletion. Therefore, various types of edible oils, soaps, and skin care products are dumped in large quantities in Wuhan, Changsha, and even Nanjing and Shanghai.

The ammunition institute also produces matches, which are also nitrated with grease. Basically, it has replaced foreign fires imported from abroad.

The salt production of Qianjiang and Yingcheng is also stable. However, Zhang Chun still limited production and did not allow exports.

Zeng Simin's Planning and Statistics Office has summed up the law, and Zhang Chun is very picky about all underground minerals. However, Zhang Chun has very few restrictions on the sustainable output of agriculture, forestry, animal husbandry and fishery.

Green Lake's electronics institute is developing rapidly, and they have no shortage of raw materials, technology, and ideas, and even silver is at their disposal. At their behest, optical microscopy technology is also developing at a rapid pace. This also contributed to the improvement of telescopes and sniper scopes. With the help of microscopes, in addition to manufacturing circuit boards, they even developed towards integrated circuit characters.

Small, the smaller the better, this is the obsession of the Institute of Electronics.

At the same time, because of the miniaturization, the board can be more functional. They developed the cathode tube display technology they got from the Germans into a display for radar. And color display is being implemented.

At the same time, electromagnetic technology is also developing. The Institute of Electronics is rapidly being divided into several research institutes.

It's just that these people are very low-key, Zhang Chun once went to Green Lake for a meeting and saw a group of people under the black pressure, but there were few people who really left an impression.

This is the difference between the personality and behavior of a technician and an executive.

In October 1921, Marin met with Sun Yat-sen's representative Zhang Ji in Shanghai and suggested that the Chinese Kuomintang send representatives to the Far Eastern Labor People's Congress, expressing the hope of establishing contact with the Chinese Kuomintang. Zhang Ji invited Ma Lin to Guilin, Guangxi.

In November, the newspaper Izvestia, which came through from Millor, praised Sun Yat-sen as a "radical" in China, and the Comintern blamed the Beijing government for praising the Chinese revolution led by Sun Yat-sen.

In December, Ma Lin arrived in Guilin, Guangxi, and discussed with Sun Yat-sen the international cooperation between the Kuomintang and the Communist Party at the base camp of the Northern Expedition.

What is wonderful is that Sun Yat-sen followed some of Zhang Chun's arguments, saying that the idea of universal harmony in Marxism was already said in China's classic doctrine as early as 2,000 years ago. Sun Yat-sen, however, agreed that China and Russia "must cooperate and help each other in their opposition to the Quadruple Alliance."

Marin passed the minutes of the meeting to the party groups in the provinces, and Jingzhou also received the minutes.

Since Jingzhou had expected this result, it was not too surprised.

Since October, Wang Zhanyuan may not have seen hope in Hubei, so he has not thought about staying in Hubei for a long time, so he has been looting finances on a large scale. The exorcism movement continued to occur in Hubei. The Hunan army Zhao Hengti and Xia Douyin sent troops to attack southern Hunan, and Sun Chuanfang was defeated and retreated to Guangji. Cao Kun and Wu Peifu had no choice but to get rid of Zhang Chun and Li Tiancai, but they had long wanted to get rid of Wang Zhanyuan. Therefore, in the name of assisting Hubei to drive out Wang Zhanyuan, Wu Peifu personally served as the commander-in-chief of aiding Hubei, and sent Xiao Yaonan to lead the 25th Division to the three towns of Wuhan, and Jin Yunju, the commander of the Eighth Mixed Brigade, was the commander-in-chief of the former enemy and led his troops to enter Cha'an Ridge. Sun Chuanfang chose to stand by in this situation, and Wang Zhanyuan was driven away.

Wu Peifu's troops had some small battles with Zhang Chun one after another, but none of them won. I had to watch Zhang Chun occupy the central area of Hubei.

Wu Peifu also knew that he couldn't be the governor of Hubei like Wang Zhanyuan. Instead, let Xiao Yaonan, a native of Hubei, be the overseer of Hubei and go back to Henan by himself.

Xiao Yaonan personally went to Jingmen to meet Liang Qichao and Zhang Chun. It is said that the Hubei people have been looking forward to autonomy for a long time, and they should watch over each other.

Zhang Chun needed to govern Xiangyang and passed through the northwest of Hubei. So it was a peace agreement. (To be continued......)
