"This is the famous Eagle engine!"

Chai Dongliang looked at a shiny engine and couldn't put it down, anything produced by Rolls-Royce looks alive, it doesn't look like a cold industrial product, but like a masterpiece of art carefully created by a master, every detail is full of beauty.

The heavy V-12 cylinders were divided into two rows of six on each side. Even a small screw is polished with a light that shines like a jewel in the light, and the surface of the engine does not have the slightest sense of blockage when touched by hand, and it feels excellent to the touch. The whole machine has the roughness of a male surname, and there is no lack of delicacy and gentleness of a female surname.

In 1884, the genius designer Royce set up a small factory for seventy pounds, first producing electricity and then automobiles. The famous luxury brand Rolls-Royce was born, and with its world-leading V-eight engine and the spirit of attention to detail, the Rolls-Royce Silver Wraith became the world's best-selling luxury car. Chai Dongliang bought a 58% stake in Rolls-Royce for £40,000 and injected another £80,000 into engine research and development. Rolls-Royce grew rapidly, and the production of Silver Ghost increased from three or five to three to five hundred vehicles per month, and now the output and profits are growing rapidly.

The drawings provided to them by Chai Dongliang were the "Eagle Engine" that was famous in World War I and World War II in later generations. In another time, the engine was invented by Royce in 1915, inspired by the V-eight-cylinder engine used by the Rolls-Royce Silver Ghost. After Chai Dongliang gave him the drawings, he quickly saw the similarities between this engine and the V-shaped eight-cylinder car engine. The Eagle engine is divided into two types: V-8 and V-12, and its inventor was originally Royce, who could naturally touch the bypass at a glance.

On another day and place, on June 14, 1919, the British pilot John ? Captain Alcock and Navigator Arthur? Lieutenant Brown flew a modified "Vimy" bomber eastward across the Atlantic Ocean from St. John's, Newfoundland, North America, to Clifton, Ireland, for the first time without landing, and became a pioneer in flying across the Atlantic.

The Vimy bomber, which completed the historic flight, was equipped with two Rolls-Royce 375-horsepower Eagle V-8 engines. At that time, there were ten aircraft competing with the "Vimy" bomber, but six of them were withdrawn for some reason, and in the end only four aircraft took off. Rolls-Royce is proud that all four aircraft are powered by their Eagle engines, a flight that has earned Rolls-Royce engines a worldwide reputation.

A few months after Alcock and Brown's successful flight, Ross? Smith and Keith? The Smith brothers, still piloting the "Eagle" powered "Vimy" plane, flew from London to the port of Darwin, Australia, in 28 days, a distance of nearly 18,000 kilometers, opening up a route from Britain to Australia for the first time.

From the Allies in World War I to the Allies in World War II, almost half of the aircraft engines used by countries such as Britain and the United States were Rolls-Royce's invention of the Eagle and its various modifications. This engine, along with its modifications, produced 160,000 units.

Feng Ru's hands were covered with oil, and his work clothes were also black and oily. He, the director of the aircraft management center, spends almost every day in the workshop, and when he is tired, he squints on the bench. A face is thin and out of shape, looking black and yellow.

Although Chai Dongliang was distressed and wanted to give him a period of vacation and let him rest well, time really waits for no one, maybe if he misses this year, the Chinese nation will miss a hundred years.

China has missed nearly a hundred years and cannot afford to waste time and again. China has suffered enough humiliation, it really can't be left to future generations to solve, many things are missed, and there is no chance to correct mistakes!

Chai Dongliang picked up a pencil and sketched the appearance of a seaplane on a few strokes on white paper.

"Director Feng, I hope you will research a six-engine airship-style large seaplane as soon as possible." Chai Dongliang looked at Feng Ru and asked.

"Governor, what is the take-off weight of the plane you want?" Feng Ru asked.

"With a take-off weight of forty-five tons, it can carry twenty-four passengers during the day and sixteen sleeper passengers across the Atlantic Ocean at night."

Hearing this, Feng Ru and the technicians from the aircraft management center gasped at the same time. The current planes can fly up to 50 kilometers and an altitude of more than 200 meters, while Chai Dongliang asked them to fly over the Atlantic Ocean with dozens of passengers!

"Forty-five tons? Can it be done? Feng Ru grinned.

Chai Dongliang said with a smile: "If you can't do it now, it doesn't mean that you can't do it next year, I believe your ability will not disappoint me." ”

Feng Ru carefully looked at the sketch drawn by Chai Dongliang, which was a monster with twelve engines driving six sets of propellers. The massive wings carry six sets of propellers, and below is a yacht-like hull. The wingspan reaches an appalling forty-eight meters, and the fuselage is divided into three decks, the main deck is the passenger area, which provides meals and accommodation, the lower deck stores fuel and carries luggage, and the top deck is the flight control room, crew members' quarters, and radio room. Since there are twelve engines, random engineers are also required.

This is a luxury yacht flying above the blue sky! This is the perfect crystallization of human dreams and modern technology!

"Dudu, what is the speed of your flying yacht design?"

Chai Dongliang thought for a moment and said: "The maximum speed is two hundred and fifteen kilometers per hour, the cruising speed is one hundred and seventy-five kilometers per hour, twelve engines, each power is five hundred and twenty-five horsepower, the maximum range cannot be less than three thousand kilometers, the crew is twelve people, if necessary, the maximum load is 52,000 kilograms!" ”

As Chai Dongliang blurted out one design indicator after another, the blood of Feng Ru and others was about to rush to the brain, they never thought that there would be such a big plane in the world!

What Chai Dongliang wants is actually the famous German Dornier seaplane in World War II, a large seaplane known as a giant air ship, which will be transformed into a giant water bomber.

Chai Dongliang's idea was to load enough torpedoes and aerial bombs on such planes, and then launch a sneak attack similar to Pearl Harbor, using the method of air raids to wipe out the combined fleet in the harbor at one time. This tactic is not very effective for the US military, blowing up and sinking a few warships is simply a drizzle for the United States, and if they sink one, they can build two, three, or even ten! And it is a fatal blow to Yueben, in this era, Yueben's national strength is not strong.

Warships of this era generally did not have air defense, and no one would have imagined that warships could be hit from the air. Therefore, the bulky fuselage of the Dornier seaplane is no longer a flaw, and its huge bomb load will ensure continuous fire strike capability.

In fact, Chai Dongliang still compressed the technical indicators, and the maximum range of the real Dornier seaplane was 7,000 kilometers, and the air time was a terrifying 33 hours. Of course, the Dornier seaplane had many flaws, slow speed, poor maneuverability, and huge targets, and if it was used as a military aircraft in World War II, it would basically be a live target. But it also has the most obvious advantage, which is that it is not too technically difficult. With the Hawk engine, it was much less difficult to develop than several famous bombers of World War II.

However, the combined fleet that attacked Yuben did not need to fly so far, and the fleet was transported to the depths of the ocean by water aircraft carriers, and then it went straight to the Kure Harbor Military Port in Yuben, and the distance was only a few hundred kilometers at most.

Chai Dongliang's plan is to make a hammer deal, kill the combined fleet of the company at a time, and then blow up the industrial areas of Osaka and Yokohama, and the results of the 40 years of farming and real estate will be basically solved. The concentration of industry in Osaka was the Achilles' heel of the small island nation.

After the sneak attack on Kure Harbor, these bulky Dornier seaplanes can be transformed into civilian airliners to serve the people.

"I know it's going to be difficult, but this mission must be completed within two years, the engine is the heart of the plane, and now we have the heart, it's up to you to fill this sea flying beast with flesh and blood! I will assist you, and in the next few days I will draw a more detailed sketch of my seaplane for your reference. This project is related to the fate of China, whether our country will continue to be humiliated as it is now, or whether it will stand tall on the east coast of the Pacific Ocean. I'm please! ”

Chai Dongliang looked at everyone's faces with embarrassment, he snapped upright, and his body half-turned to salute everyone.

Feng Ru's expression was solemn, his expression was uncertain, and after a long time, he shook his head and said, "Dudu, this task is too important, please forgive me for not accepting it." ”

Chai Dongliang was stunned: "Why?" ”

Feng Ru sighed and said: "The current Eagle engine power is still insufficient, but this is not the main problem, the most important thing is that this plane is so huge, it is definitely not possible to use wood as the fuselage, not to mention the waves and winds, it is its own weight will break the wooden wings and dragons, and after flying in the air for a long time, the friction and the heat of the engine can even ignite the aircraft." If it is made of steel, it will be too heavy and difficult to fly, please forgive me for my incompetence! ”

Feng Ru bowed ninety degrees, his face full of bitterness.

Chai Dongliang then remembered a fatal problem, there is no suitable material in this world to make a behemoth like the Dornier seaplane. The low level of the material industry is still the biggest obstacle to China's industrial development until the 21st century.

"Dudu, your idea is very good, the design is novel and unique, but my ability is really limited, you better ask for another master." Feng Ru looked helpless.

Chai Dongliang said with a smile: "This is indeed that I was not thoughtful enough. Suddenly, a flash of inspiration flashed in his mind: "What if it is produced with aluminum?" Aluminum is light enough! ”

Feng Ru shook his head resolutely: "Although aluminum is light, it is too soft, and it is okay to produce small aircraft, and it is impossible to produce large aircraft." ”

Chai Dongliang said with a smile: "So, what if there is a material that is as light as aluminum and as tough as steel?" What do you think? ”

Feng Ru said with a bitter face: "But no!" As far as I know, even the European and American powers do not have such materials. ”

"If so, I mean if! If anything, do you have the confidence to make such a large seaplane? ”

Feng Ru pondered for a moment and said, "If there is, I will definitely be able to build the plane you want within two years." ”

Chai Dongliang patted him on the shoulder and said, "Okay, I'll wait for your words!" ”

??? Dividing line ???

Back at the Military Advisory Office, Chai Dongliang quickly turned on the computer, and the book friend group was bragging and farting. "I love little wolf dogs" is obviously already a goof, and there are no more men and **.

"Brothers, who knows how the aluminum alloy used in airplanes is made?"

The group of book friends was silent for a moment, and after a while, Ma Xiaobraid sent an extremely depressed avatar: "I've seen aluminum alloy doors and windows, who knows what they use on the plane?" ”

Chai Dongliang smiled bitterly: "Brother, you go to Baidu." ”

Ma Xiaobraid said disdainfully: "You won't go to Baidu yourself?" ”

Chai Dongliang said helplessly: "I, am I not inconvenient?" ”

Xiaofang, a beautiful book friend, asked very fiercely: "Is it inconvenient for men to have a few days every month?" ”

Chai Dongliang suddenly sweated.

Xiao Fang said unrelentingly: "I am the heroine!" Why do you give me so few scenes? ”

Chai Dongliang hurriedly said flatteringly: "Beauty, first help me Baidu take a look at the aluminum alloy information used in the plane, I will definitely increase your role, and I will never break my word!" ”

Xiao Fang happily dived at this time, and after a while she came out again: "I checked, aluminum alloy was invented during World War I, but aluminum alloy doors and windows are not the same thing as those used in airplanes!" Airplanes use aluminum-magnesium alloys, or aluminum-lithium alloys and the like. I'll send you a table with the composition of various materials. ”

Chai Dongliang hurriedly thanked him, and then downloaded the materials to the machine from the group share.

After looking at it for a long time, he somewhat understood that aviation aluminum was a low-content Al-Mg-Mn alloy.

●Chemical Composition:

Aluminum Al: Residual Silicon Si: ≤ 0.40 Copper Cu: ≤ 0.10 Mg Mg: 0.6 ~ 1.4 Manganese Mn: 0.15 ~ 0.40 Titanium Ti: ≤ 0.15 Iron Fe: 0.000 ~ 0.400 Note: Single: ≤ 0.05; Total: ≤0.15 ● mechanics surname can:

Tensile strength σb (MPa): ≤98Elongation δ10 (%): ≥15 Chai Dongliang's head hurts when he sees a string of chemical symbols, he was not very good at science when he went to school, and after working for a few years, he returned everything he had learned to the teacher.

Where do you start?
