Back to the Republic of China to be a editor

The Kiev Electrotechnical Research Institute is the research institute where Lebedev used to stay, and the monastery used by the institute as a dormitory building is where he and Tang Hua developed the MES-M computer together.

Lebedev said "Oh", but still focused on dealing with the steamed crab on the plate, and after a while he said: "The dean of the Electrical Engineering Research Institute is not bad, you should know that when we were in the institute, The dean is very supportive of our computer group. It is the Ukrainian Academy of Sciences... remember to remind me when the Ukrainian Academy of Sciences wants to buy Chinese computers."

……

At the Shanghai Institute of Computer Science, Lebedev's supercomputing hall is still empty, and there is only one desk for him in the huge room that can hold eight table tennis tables.In September last year, the T9 was assembled and sent away here.From January to February this year, T50 was also assembled and sent away here.

The decommissioned TC50 supercomputer was transported back to Beijing by Tang Hua, and it was hidden in the Beijing laboratory of the Institute of Modern Physics, Chinese Academy of Sciences, with three layers of security inside and outside. Although the TC50 was eliminated by the 50 Center, it is still capable of killing the supercomputers of any other country on the planet.The director of the Beijing Laboratory of the Institute of Modern Physics... is Deng Jiaxian.

The prototypes of TC52 and T52 have not yet come out. Lebedev's job is to improve the operating system and develop the next version, using the two T51 computers next door.

Tang Hua spread out the drawings of the TC52 core computing unit, and the chief engineer of the electronics factory attached to the computer department took a deep breath.

"Minister Tang... Are you going to make a new size cabinet?"

Tang Hua (smiling like a god of war with crooked mouth): "After the new basic components come out, the core computing unit must of course be redesigned. The basic components become smaller, and the computer can also be made smaller. The cabinets as big as T50 and T51 look like nothing. Not advanced."

Engineer: "Then I'll contact the cabinet factory in Taicang immediately. I'll take a look at the drawing of the cabinet...Mr. Tang, why is there no place for the display screen?"

The display screen that the engineer refers to is a segment code screen with three lines on the T51 computer that can display numbers and letters. When the T51 computer was offline, the screen that could display letters was new to the engineers of the computer institute and the electronics factory. A group of people gathered around the testing machine and typed various letters on the keyboard. A group of people had a great time.The height of the T52 computer cabinet in front of me has been reduced from 51 meters of T2.2 to 1.5 meters. There are still 12 jacks for cylindrical computing units, but there is no segment code screen above the 12 jacks, and it directly transitions to the top of the cabinet. .

"The display system of the new computer is provided separately, and it is not integrated with the cabinet." Tang Hua said, "The new display system... will be delivered later, and it will definitely be delivered on January 1952, 1."

On the T51 computer, there is a very complicated circuit board above the 12 computing units. Let the numbers output by the computer be converted to generate special codes and light up certain designated lamps on the segment code screen to display numbers or letters. .

The T52 computer does not need this complex circuit.

In other words, it was installed elsewhere.

"January 1952, 1?" said the engineer. "Is it that accurate? The delivery date won't be off the hook, will it?"

Tang Hua: "My schedule is a bit tight this time, and I can't go to Guangzhou, but the project delivery date of Huawei's projects will not lose the chain. ... Probably not."

……

Guangzhou, Huawei TV factory laboratory.

More than a dozen workbenches are scattered with various electronic components, including picture tubes, picture tube parts, blown up picture tube corpses, manuals, coiled circuit diagrams, components, circuit boards, magnetic cores, and of course various Kind of electrician tools.

Under the workbench, six or seven pull-out folding beds are arranged in a haphazard manner, and a rough man with disheveled hair is lying on each folding bed.

The lab's alarm clock rang, and the rough researchers opened their eyes one after another. "It's 8 o'clock in the morning, let's get up almost."

After a night of sleep in the laboratory, the researchers put away their cribs and went to find their respective mug towels in their flip flops.

In the past three weeks, all the staff in the laboratory have been in this working state.I work until 10:11 or 8:[-] in the evening, and sleep on the folding bed under the workstation, and get up at [-]:[-] the next day.The living security is pretty good, with a big electric fan above the head, three meals plus supper are good meals, and there is no need to pay for it from the salary, and there is a place to wash and take a shower not far from the house.

"Delivery on January 1, leaving the factory on December 1, making a production organization plan on November 12, and passing the test on October 1." The deputy leader of the display team was still confused, "according to the time The line is pushed back like this, and there is really not much time left for us.”

"More than 100 characters scare you like this," said the team leader, "Have you read the planning document signed by Minister Tang? Next year, we will start to make more than 6000 characters!"

Deputy team leader: "Do you think we Chinese are dragged down by Chinese characters? It would be great if Chinese characters were spelled out!"

Team leader: "We are responsible for solving technical problems, not eliminating technical problems. Thousands of words... At that time, we will recruit more people..."

Chapter 175, Mutual research between battles

West of Tokyo, Yokota Air Force Base.

This is the seat of the Fifth Air Force Command, as well as the United Nations Air Force/Far East Air Force Command.After taking over the airport from Japan, the U.S. military quickly obtained the right to use the land from the Japanese government, and expanded it into a comprehensive air base that can take off and land B-29 heavy bombers.During the war, about half of the B-29s that bombed North Korea took off from here.

At Yokota Air Force Base, a hangar that used to house B-29s is now a high-security, mysterious area.A cordon was set up outside the hangar, and guards stood guard 24 hours a day, but there were always people entering and leaving the hangar door. From time to time, two jeeps rushed to the hangar door, and several people in suits or military uniforms went up and down.

Lieutenant General George Stratmeyer, commander of the Far East Air Force, heard that the research work had made significant progress, and immediately drove from the headquarters building to the hangar.After getting out of the car and walking into this huge building with bright lights, the Tu-2 bomber picked up from Yamato Island was basically assembled back by the intelligence personnel.

In the hangar, Partridge also saw other senior officials of the US military or the United Nations: Major General Partridge, commander of the Fifth Air Force, Charles Willoughby, head of the US Far East Intelligence Command, and several people in suits People, it is said that they flew over from the United States on a special trip a few days ago.

"In fact, 50% of the assembly work is useless. It's just that the model assemblers who are not professionally qualified are boringly restoring the shell of Figure-2." A man in a suit who claimed to be Paul Freeman pointed at the scene and said, "Only this The small box is the key....Because of this, the assembly and restoration of this small box took half of our manpower and working time."

When the Tu-2 bomber that crashed on the beach of Yamato Island was discovered by U.S. military intelligence personnel, they took pictures while picking up parts at the scene, which provided the most important information for Paul Freeman to restore the aircraft.Paul Freeman's attention was caught in the first photo taken by intelligence agents entering the interior of the plane that was fighting the fire. In the photo, a badly injured volunteer pilot, possibly the navigator, turned and crawled back, clutching a grenade.Due to excessive blood loss, the navigator died before he could finish what he had to do. His right hand holding the grenade finally pointed in the direction of a broken iron box installed in the front of the plane.

Paul Freeman's team quickly recovered the iron box from loose parts brought back to Japan.The Chinese actually attached a pack of explosives to the bottom of the iron box to make a self-destruct device.When the plane fell, the explosives had already exploded, and the iron box was blown into several pieces.But this self-destruct device is not too professional, and the vital thermite combustion components are not mixed with the explosives, so the iron box is only blown to pieces instead of completely destroyed.Under the leadership of Paul Freeman, seven or eight people were busy for 5 days, and they just put together the iron box part by part.

"This iron box seems to be a very important confidential equipment. So what is its function, have you analyzed it?" Strattmeyer asked.

Paul Freeman: "My team restored the iron box three days ago... 75 hours ago to be exact. During those 75 hours, Johnson's team worked 24 hours a day to verify its function. research. Johnson said he just came up with a preliminary analysis."

"Good day General, good day Mr. Willoughby. This device is the controller for the radio-guided bombs used by Chinese bombers."

Johnson came up and explained his findings to generals and executives.

"Radio-guided bombs are not new weapons, so I won't introduce Chinese radio transmitters and joysticks."

"Army Aviation, US Air Force have radio guided bombs, as far as I know the Air Force used Tasong in North Korea, but you stopped using this bomb a few months ago, right?"

Partridge: "Its accuracy is not that ideal... Of course the most deadly reason is that there was a martyrdom accident, which destroyed a B-29."

Strutmeyer, an air force lieutenant general, also generally knows what Johnson said.But in order to express his point clearly, Johnson still intends to start from the beginning.

"Whether it is a radio-guided bomb, whether it is Fritz-X, Tasson or Asson, the principle is similar, that is, the remote control is used to correct the deviation during the bomb's falling process. When the bombardier finds that the bomb deviates from the target, press the remote control handle, and the bomb will After receiving the command from the remote control, the tail rudder deflected, allowing the bomb to move in the opposite direction of the deviation. That is to say—”

Johnson drew a cross on the blackboard behind him, marked the flight distance unit on the X-axis, and the deviation on the Y-axis, and then drew a sinusoidal function waveform. "After the remote control command is issued, the bomb will turn from positive deviation to negative deviation. When the bombardier observes the negative deviation, press the handle again. If the bomber operates correctly, the bomb will turn from negative deviation to positive deviation again. Also That is to say, in the entire flight trajectory of the bomb, it is like a sine function. With the remote control of the bombardier, the deviation of the bomb fluctuates from positive to negative. If the maximum deviation is 100 meters, then when it hits the ground, The error will be a random value between 0 meters and 100 meters, and if averaged, the average deviation is 70.7 meters."

"This is one of the reasons why the efficiency of guided bomb operations is not high...but the Chinese guided bomb controller has overcome this defect to a large extent." Speaking of the topic, Johnson became excited. "There is a strange circuit composed of transistors, impedances, and capacitors set in this box. The bombardier finds that the bomb has deviated. When the handle is pressed, the remote control signal sent will be adjusted through this circuit. Finally, the trajectory of the bomb will be like this. "

Johnson drew another curve on the graph, this one with decreasing amplitude until the vibrations died down and became a line that coincided with the x-axis.

"Last year we studied the records of the Chinese army using guided bombs in the battle of Penghu. In the battle of Yamato Island, we also obtained the records of the South Korean coast battery being attacked. This is consistent with my analysis of the controller. Using this This kind of controller, the theoretical hit accuracy of guided bombs is very high. So we bombed the Qingchuan River Bridge, 28 B-29s dropped 28 bombs, and only hit 6, while the Chinese dropped 8 bombs and destroyed 5 20-meter X20 meter shore artillery positions."

Both Stratmeyer and Partridge, commander of the Fifth Air Force, were in long thought.

"Our bomber also uses a similar controller, is it easy to do? Can it also be used to improve the 'bat'?"

Johnson: "The controller has been basically restored, and I have drawn the circuit diagram of the controller. So if the Air Force needs it, it should be imitated. However, guided bombs without glides have other disadvantages. For example, bombers must be time, easily shot down by enemy fighter jets or anti-aircraft guns..."

"I would like to warn you that there are some strange parts in this controller." Charles Willoughby interrupted Johnson, coming over, reaching into the controller box, and pulling out a transistor.

"I've seen this part before. ... There is a big secret hidden behind this little thing."

……

At the moment when the U.S. military stopped to take a breath, the U.S. military was not the only one spying on the volunteers.Volunteers also had some unexpected gains on the battlefield.

The battlefield of the Dongducheon counterattack was controlled by the volunteers after the battle.The U.S. troops were driven back to the Han River. Although the Volunteers planned to withdraw from the Han River Plain, they spent three to five days cleaning the battlefield.

"What's on this Yankee's carbine?" A signalman picked up the discarded M1 carbine in the trench. "Does anyone know how to dismantle it? I can use it myself after dismantling it."

The signal soldiers were not issued semi-automatic. Of course, in North Korea, many non-combat volunteers who were close to the battlefield would use a captured American gun. The light, small and flexible M1 carbine was the best choice.
