blood feud

Bai Shujie came to Meng En's personal laboratory and found that there were six newly dug large caves and 39 more people.These people do only one thing: calculations, all of which are doing a lot of complicated calculations!

The calculation tools used by these people are also various: in addition to an electronic punched card computer, there are two hand-cranked mechanical computers, even slide rules and a large number of Chinese abacus!

Complex aero engines and aerodynamics, complex ship turbines and hydrodynamics all require huge calculations.

Bai Shujie found that the only electronic punched card computer weighed at least ten tons, and it was an outright colossus.And the punched paper and paper tape are piled up like a mountain, which is worthy of the name.

Even so, it was brought over by Munn from Germany. It was the core baby of their engine team. It was reassembled and put into use only three months ago. It was also an important weapon for them to complete engine modification and invention.

Seeing this huge monster made of vacuum tubes, Bai Shujie finally remembered the electrical components—transistors and audio tapes—to reduce the size of the computer and greatly improve the computing power.

It is precisely because Bai Shujie saw the "latest and most advanced old antiques", he became very emotional, and said something inadvertently, and then he was caught by Meng En, as well as more than 50 people from the Institute of Physics and Mathematics. Experts, unite to "close confinement" for a month!

These words are as follows: "Since everyone can make a simple ore radio, why didn't they think that the volume and weight of this computer can be reduced by [-] times by replacing the vacuum tube with a transistor; The perforated paper tape can increase the computing power of this computer by [-] million times, and it can also automatically store data and use it repeatedly.”

Under the "coercion and lure" of dozens of experts, Bai Shujie was forced to "invent" crystal diodes and triodes within a month, and produced semiconductors, transistor element formulas, and drawings of diodes and triodes. There are basic data issues with audio tapes.

Bai Shujie belongs to the lifelong honorary president of the "Pyongyang Comprehensive Research Institute". This time, he took a month out of his "busy schedule" to organize dozens of experts to conduct "great scientific research" and made "epoch-making breakthroughs" in the field of computers. great contribution".

The experts agreed that if the dean does not become a general, but calms down to conduct scientific research, he will be the greatest "natural scientist" in human history, the kind that does not exist!

Experts from the Institute of Physics, the Institute of Mathematics, and the Institute of Materials obtained the "invention patent drawing", which is naturally a treasure, and then rushed away to devote themselves to the "great" practical application research work.

Only now did Bai Shujie have the opportunity to communicate with Meng En, why there is such a huge calculation group.

Munn said with a smile: "Commander-in-chief, I always think that the turbojet engine should have a greater use, so it needs a lot of calculations, and then complete the transformation."

"Through half a year's calculation, the results obtained now are very clear. Although the turbofan engine has a large windward area and is not suitable for fighter jets, it definitely has a brighter future than the turboprop engine in terms of transport aircraft and high-speed bombers."

"At present, there has been a clear conclusion that turbojet engines and turbofan engines have their own unique advantages. Especially in terms of large transport aircraft, turbofan engines have the huge advantages of being more fuel-efficient and reducing noise."

"So, I transformed two long-range high-speed reconnaissance planes into one, using four turbofan engines. When flying at subsonic speed, it has unique advantages. The reconnaissance plane that is currently being tested is a turbofan Engine. Experiments have shown that using a turbofan engine is smoother and easier to control.”

"The maximum take-off weight is 175 tons, the maximum level flight speed is 980 kilometers, and the practical ceiling is 14500 meters. The cruising speed at an altitude of 9800 meters can reach 800 kilometers. It can carry 85 tons of fuel, a payload of 30 tons, and a range of 14500 kilometers; it can carry 65 tons. Fuel, with an internal load of 40 tons and an external load of 8 tons, the voyage can reach 11000 kilometers."

"Isn't this fucking too big? With such a long voyage, who will I use to hit?"

Bai Shujie calculated silently in his mind, and the cost reached 380 million US dollars, which is already close to the American B-52 strategic bomber.I don't need many such strategic bombers, unless I sell them to others to make money.

Thinking of this, Bai Shujie smiled and said to Meng En: "Then, according to your idea, complete the modification of the two reconnaissance planes. The originally planned 12 Furylong bombers are also replaced with turbofan engines. I hope you can complete it this year. "

In fact, the main purpose of Bai Shujie's coming here was to talk to the experts from the Institute of Physics about the improvement of "magnetic sensors", "sonar sensors" and "passive radar".Unexpectedly, it was delayed for a month by those experts who "forced scientific research".

However, considering that if the transistor is successfully developed, the weight and volume of all transmitters, receivers, and signal processors will be greatly reduced, and the sensitivity will be greatly improved.

Therefore, Bai Shujie suddenly remembered a big event. He hurried back to the Institute of Physics, adjusted his research plan for the improvement of passive radar, and proposed the concept of "phased array radar" for the first time.

Phased array radar (par), that is, active electronically scanned array radar (aesa), or passive electronically scanned array radar (pesa), refers to a class of beams that are changed by changing the synthesis method of the beam emitted by the antenna surface array. Radar in scan direction.

In the absence of transistors, detectors and filters cannot be miniaturized, and small electronic computers cannot be manufactured, so it cannot be established.But now that research on transistors has started, research on phased arrays should be carried out simultaneously.

Since the radar antenna is turned into an array, it is to juxtapose countless individual antennas, that is, it is composed of many radiating units and receiving units (called array elements).

The number of units is related to the function of the radar, and can range from hundreds to tens of thousands.These units are regularly arranged on the plane to form an array antenna.

Using the principle of electromagnetic wave coherence, the direction of the beam can be changed to scan through computer control of the phase of the current fed to each radiation unit, so it is called electrical scanning.

Because the working basis of this radar is a phase-controllable array antenna, the name "phased array" comes from this.This is the direction of radar development in the next few decades, and basic research must be advanced.

Bai Shujie knew that this kind of radar would be widely used in less than ten years.If you don't hurry up now, you won't be able to suppress the enemy in terms of early warning, and you won't be able to achieve the decisive goal of "find the enemy first, and fire first".

In order to use the upcoming "phased array radar", Bai Shujie issued an order to Munn's team and the aircraft factory: "Order on Changing the Structure and Layout of Fighter and Attack Aircraft Fuselage".

The order requires that the new generation of single-engine jet fighters should be changed to the design of the belly air intake; the new generation of twin-engine fighter attack aircraft should be changed to the design of the air intakes on both sides of the fuselage. The 4 cannons are evenly distributed on the left and right wings, and the space at the nose should be reserved for the installation of new radars in the future.

In this order, Bai Shujie also proposed a basic plan for various structural data of future fighters, and also listed relevant parameters.The purpose of doing so is mainly to reduce the time for the expert group to make detours.What Bai Shujie needs is time, not "fine" research results.

After the test of "dozens of research results", all the "ideas" that Bai Shujie came up with are basically the "optimal design", which has become the unanimous opinion of all the experts of the Comprehensive Research Institute.

It's not that Bai Shujie wants to plagiarize other people's things. If others haven't invented it, it's not plagiarism. Anyway, he thinks so.

After receiving Bai Shujie's order, Meng En finally called out his luck: "Fortunately, the commander-in-chief had the foresight to start the production project of jet fighter in advance. If the fuselage has already been produced, it will become a fantasy to change the layout and structure." !"

At 1940 o'clock noon on March 3, 12, two reconnaissance planes transformed by Meng En took off carrying 12 tons of conventional high-explosive bombs, and their target was Nanjing City.It's a pity that there are many compatriots in the city of Nanjing, so we can't act indiscriminately.

Otherwise, Bai Shujie would definitely order two planes to carry four 4-ton cloud bombs and four 10-ton napalm bombs, and use two rounds of bombing to directly raze the city of Nanjing to the ground!

The cruising speed and cruising altitude of the Nulong reconnaissance plane have already surpassed the fighter jets of the little devil, and also exceeded the strike range of the little devil's anti-aircraft artillery, so the two furious dragon reconnaissance planes do not need escort at all, and the two crews of 2 people fly directly. Go over there, then drop the bomb and you're done.

Because history has not changed, the traitor Wang Jingwei still released the so-called "Peace Declaration" on time, saying nonsense, "I hope the Chongqing government will abandon its prejudices, stop armed resistance immediately, and work together to realize the peace plan."

Wang Jingwei and his wife have repeatedly argued that their actions were "not traitors betraying the country, but saving the country."

However, Wang Jingwei's so-called "Peace Declaration" did not mention at all that the aggressors should stop attacking, but asked the Chongqing government to stop resisting.Anyone whose head has not been kicked by a donkey knows what kind of nature it is.

The last time Bai Shujie ordered two reconnaissance planes to drop two 2-ton conventional bombs as they passed by Nanjing City, which was regarded as a warning.But he didn't scare Wang Jingwei, Bai Shujie felt very ashamed.

Bai Shujie did not expect to blow up Wang Jingwei this time. He had no other request, but to completely blow up the "Presidential Palace" and give Wang Jingwei's "so-called Nanjing government" a blow.

At the same time, Bai Shujie ordered Xiao Lamei's high-power radio station to officially announce the terms of the secret agreement signed by Wang Jingwei and the little devil.The core content is nothing more than three aspects:

First of all, recognize the legal status of the little devil in the occupied place, confirm the "existence of a fait accompli" of the little devil, and "compensate for the loss of rights and interests suffered by Japanese subjects in China since the incident." This is the most typical "land cession." After that, pay for it!

Secondly, "preventing communism is the common priority of both sides", so "China recognizes the Manchurian Empire, Japan and Manchuria respect China's territory and sovereignty, and Japan, China and Manchuria restore state-to-state relations."

In order to "guidance the Chinese government", "Japan sent the required advisers to the central government".This is the same treatment as the puppet Manchukuo, and there needs to be an overlord.

Thirdly, in order to ensure the co-prosperity of Greater East Asia established by the little devil, the little devil has the priority to exploit the "buried resources", and the tariffs must be "deposited" in the "pure gold bank" of the little devil!

As soon as this telegram came out, there was an uproar both at home and abroad.

After all, what happens next, let's see the breakdown in the next chapter.
