Bai Shujie came to Meng En's personal room and found that there were six more newly excavated caves inside, and there were also 39 more people. These people do one thing: calculate, all with a lot of complex calculations!

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

Complex aero engines and aerodynamics, complex ship turbines and fluids, all require enormous calculations.

Bai Shujie found that the only electronic punch card computer weighed at least ten tons, and it was an outright behemoth. And the perforated paper and paper tape are piled up, worthy of the name of "sweat cows".

Even so, this is the core of their engine team, which Munn brought from Germany, and it was only reassembled and put into use three months ago, and it is also an important weapon that they can complete the engine modification and invention.

Seeing this behemoth composed of vacuum tubes, Bai Shujie finally remembered the electrical components -- transistors and audio tapes -- that reduced the size of the computer and greatly increased the computing power.

It was precisely because Bai Shujie saw the "latest and most advanced antiques" that he was so moved that he inadvertently said something, and then he was "confined" for a month by Meng'en, as well as more than 50 experts from the entire Institute of Physics and the Institute of Mathematics!

Here's what he said: "Since everyone can make a simple ore radio, why haven't we thought that replacing vacuum tubes with guò transistors can reduce the size and weight of this computer by five hundred times; Replacing punched paper tapes with a tape recorder can increase the computer's computing power by a factor of 100 million, and it can also automatically store and reuse the computer. ”

Under the "coercion and temptation" of dozens of experts, Bai Shujie was forced to "invent" the crystal diode and transistor within a month, and came up with the formula of semiconductors and transistor elements, drew the drawings of diodes and transistors, and of course, the basic number of audio tapes.

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

The experts unanimously agreed that if the dean did not become a general, but calmed down and conducted scientific research, he would surely be the greatest "natural scientist" in the history of mankind, and there is no such thing!

The experts of the Institute of Physics, the Institute of Mathematics, and the Institute of Materials obtained the "invention patent drawings", which were naturally like a treasure, and then roared away and devoted themselves to the "great" practical application research work.

Only then did Bai Shujie have the opportunity to communicate with Munn why such a large computing group appeared.

Munn smiled and said, "Commander-in-Chief, I always think that turbojet engines should have a greater purpose, so it takes a lot of calculations and then complete the modification. ”

"After half a year of calculations, it is now clear that turbofan engines, although they have a large frontal area and are not suitable for fighters, have a much brighter future than turboprop engines in terms of transport aircraft and high-speed bombers."

"At the moment there is a clear conclusion that both turbojet and turbofan engines have their own unique advantages. Especially in large transport aircraft, turbofan engines have the great advantage of being more fuel-efficient and reducing noise. ”

"So, I converted one of the two long-range high-speed reconnaissance planes, using four turbofan engines. When flying at subsonic speeds, it has unique advantages. The reconnaissance plane that is now being tested is a turbofan engine. The real yàn shows that using a turbofan engine is smoother and easier to handle. ”

"The maximum take-off weight is 175 tons, the maximum level flight speed is 980 kilometers, and the practical ceiling is 14,500 meters. Cruising speed at an altitude of 9800 meters, it is possible to reach 800 km. Carrying 85 tons of fuel, effective load of 30 tons, range of 14,500 kilometers; Carrying 65 tons of fuel, 40 tons of internal load and 8 tons of external load, the range can reach 11,000 kilometers. ”

"It's too fucking big, isn't it? With such a big voyage, who is Lao Tzu used to fight? ”

Bai Shujie silently calculated in his heart that the cost reached 3.8 million US dollars, which is close to the American B-52 strategic bomber. You don't need a lot of such strategic bombers yourself, unless you sell them to someone else to make money when the time comes.

Thinking of this, Bai Shujie smiled and said to Meng En: "Then first complete the modification of the two reconnaissance planes according to your plan." The original 12 Raging Dragon bombers have also been changed to turbofan engines, and I hope you will complete them this year. ”

In fact, Bai Shujie's main purpose was to talk to the experts of the Institute of Physics about the improvement of "magnetic sensors", "sonar sensors" and "passive radar". I didn't expect to be delayed by those experts' "compulsory scientific research" for a month.

However, 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 major event, he hurriedly came back to the Institute of Physics, adjusted his research plan for the improvement of passive radar, and put forward the concept of "phased array radar" for the first time.

Phased array radar (PAR), also known as Active Electronically Scanned Array Radar (AESA), or Passive Electronically Scanned Array Radar (PESA), refers to a type of radar that changes the direction of the beam scan by changing the beam emitted by the antenna surface array.

In the absence of transistors, detectors and filters could not be miniaturized, and small electronic computers could not be manufactured, so it could not be established. But now that we are starting with transistors, phased array research should be carried out simultaneously.

Since the radar antenna is turned into an array, it is to use an infinite number of individual antennas in parallel, that is, it is composed of many radiating and receiving units (called array elements).

The number of units depends on the function of the radar, which can range from a few hundred to tens of thousands. These units are arranged on a plane in a certain pattern to form an array antenna.

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

Because the basis of the work of this radar is a phase-controllable array antenna, the name "phased array" is derived. This is the direction of radar development in the coming decades, and basic research must be advanced.

Bai Shujie knows that in less than ten years, this radar will be widely used. If we do not get a good grasp of it now, it will be impossible to suppress the enemy in terms of early warning, and we will not be able to achieve the decisive goal of "discovering the enemy before the enemy and firing on the enemy first."

In order to use the upcoming "phased array radar", Bai Shujie issued an order to the Munn group and the aircraft factory: "Order on Changing the Structural Layout of the Fuselage of Fighters and Attack Aircraft."

Order requirements: The new generation of single-engine jet fighters will be changed to the design of the belly air intake; The new generation of twin-engine fighter-attack aircraft has been changed to the design of air intakes on both sides of the fuselage. The four guns are evenly distributed on the left and right wings, and the space in the nose part should be set aside as the installation space for the new radar in the future.

In this order, Bai Shujie also put forward a basic plan for the various structures of future fighters, and also listed the relevant parameters. The main purpose of this is to reduce the time for the Group to take detours. Bai Shujie needs time, not "refined" research results.

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

It's not that Bai Shujie wants to plagiarize other people's things, if others don't invent it, it's not called plagiarism, anyway, that's what he thinks.

After receiving Bai Shujie's order, Munn finally shouted luck: "Fortunately, the commander-in-chief had the foresight to start the production project of jet fighters in advance. If the fuselage has already been produced, it will become a fantasy to change the layout structure! ”

At 12 noon on March 12, 1940, two Nulong reconnaissance planes transformed by Munn took off with 30 tons of conventional high-explosive bombs, and the target was the city of Nanjing. It's a pity that there are a lot of compatriots in Nanjing, and they can't mess around.

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

The cruising speed and cruising altitude of the Angry Dragon reconnaissance plane have already exceeded the combat aircraft of the little devils, and they have also exceeded the strike range of the little devil's air defense artillery, so the two Angry Dragon reconnaissance planes do not need to escort at all, and the two crews of 26 people fly directly over, and then drop the bombs and forget it.

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

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

However, Wang Jingwei's so-called "peace declaration" did not mention that the aggressors should stop attacking, but demanded that the Chongqing government stop resisting. As long as the head is not kicked by a donkey, everyone knows what the nature of this is.

The last time Bai Shujie ordered two reconnaissance planes to drop two 2-ton conventional bombs when passing by Nanjing, which could be regarded as a warning. But without scaring Wang Jingwei, Bai Shujie felt very embarrassed.

Bai Shujie did not expect to be able to blow up Wang Jingwei this time, and he had no other demand, that is, to completely blow up the "presidential palace" and give Wang Jingwei's "so-called Nanjing government" a disadvantage.

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

First of all, it is necessary to recognize the legal status of the little devils in the places they have occupied, to determine the "existence of a fait accompli" and to "compensate for the loss of rights and interests suffered by Japanese subjects in China since the incident." This is the most typical "land cut" after the compensation!

Secondly, "Defense. The common party is the common priority of both sides", so "China recognizes the Manchurian Empire, Japan and Manchuria respect China's territory and sovereignty, and Japan and Manchuria restore diplomatic relations." ”

In order to "guide 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 emperor.

Thirdly, in order to ensure that the little devils build a greater East Asia co-prosperity, the "buried resources" of the little devils have the right of first refusal, and the tariffs should be "deposited" in the "Zhengjin Bank" of the little devils!

As soon as this power came out, it immediately set off an uproar at home and abroad.

After all, what happens next, let's see how it will be broken down next time.
