(Today's update is awesome!) Thank you to the brothers who rewarded and voted for the monthly ticket, and I look forward to continuing tomorrow! Of course, the fish head will continue to explode! ）

Aircraft maneuvering during World War I was still in a relatively early stage.

If the aircraft of the 21st century are compared to the Maybach, the aircraft of the First World War era are electric tricycles. At this time, the aircraft control is completed by the joystick and the foot pedal, and the forward or backward pull of the joystick can drive the elevator to deviate down or up, so that the aircraft can pitch down or up. Pressing the joystick to the left or right causes the aileron to deflect, causing the aircraft to roll to the left or right. The foot pedal is connected to the vertical tail, and when the left foot is pushed, the vertical tail is deflected to the left, and the nose is deflected to the left; Conversely, the nose of the aircraft is biased to the right.

Qin Zhiyuan is now sitting on an "electric tricycle", controlling the joystick and flying to Corsica.

This is a single-wing twin-engine fighter manufactured by the Renault factory according to Qin Zhiyuan's design, Qin Zhiyuan really can't stand the two-wing or three-wing fighter at this time, and insists on using a single wing. At this time, the aircraft uses double wings for a reason, the use of monoplanes must increase the area to improve aerodynamic capabilities, but because of material problems, the use of monoplanes must strengthen the structure, which will increase the weight of the aircraft and affect the performance of other aspects.

Just like the tank's range is not enough to increase the auxiliary fuel tank, Qin Zhiyuan's response method is still simple and rude, since the engine capacity is not enough, then increase the number of engines, and the result is to make up such a strange thing that is free from fighters and bombers.

Qin Zhiyuan called the plane a heavy fighter.

It is indeed heavy, almost twice as large as an ordinary aircraft, and almost half as much heavier, but at the same time the number of engines has doubled. These changes have led to a significant increase in the aircraft's performance, with the flight speed increasing from 180 kilometers per hour to 230 kilometers per hour, the flight altitude from 3,800 meters to 5,600 meters, and the flight range from 350 kilometers to 570 kilometers.

The flight distance is the only thing that Qin Zhiyuan is dissatisfied with, because of such performance, he still has to refuel once in Marseille to fly to Corsica.

Fortunately, this is not a serious problem.

If Qin Zhiyuan can put more effort into optimizing the aerodynamics of the aircraft, even if it is just to get a fairing out, the flight distance of the aircraft can be greatly improved, but Qin Zhiyuan doesn't want to toss, there are good things Qin Zhiyuan doesn't want to give to the allies, if it weren't for Qin Zhiyuan's convenience to use, even this lite version of the heavy fighter, Qin Zhiyuan is unwilling to take it out.

The biggest improvement over the previous aircraft is the cockpit design. The single wing is not a new technology, nor is the twin engine, the enclosed cockpit is the real first, with this, Qin Zhiyuan can travel back and forth between Paris and Corsica in winter, and no longer afraid of wind and snow.

Unlike the rotary cylinder engines commonly used in France, Qin Zhiyuan's aircraft uses the in-line engines commonly used in Germany. The two Xuanyuan brothers, who graduated from the University of Aachen, were deeply influenced by the Germans in their designs and had a soft spot for in-line engines, so whenever they had the opportunity, the two brothers immediately applied in-line engines to Qin Zhiyuan's aircraft.

The two Xuanyuan brothers have diverged in their research directions, the eldest Long Chengxuan, that is, Tom, is inclined to materials, and the second Longchengyuan, that is, Tony, is still focusing on the study of engines. The two are not in conflict, materials and engines are both industrial boosters, basically there is no priority, Qin Zhiyuan does not favor one over the other.

One of the most obvious effects of technological improvement is to make people's lives more convenient, when using airplanes as a means of transportation, Qin Zhiyuan only took less than 5 hours to arrive in Corsica, and in the past, if you take a train and a boat, this time will take a day at the earliest.

In the open space next to the Thunder Cliff Castle, an improvised airport had been built, and Qin Zhiyuan only circled around before adjusting the nose of the plane to the runway and start landing.

"How? What do you think? "Tony is most concerned about the performance of the engine, and as soon as Qin Zhiyuan got off the gangway, Tony rushed over to ask.

"Not bad, stable performance, plenty of power, the key is not cold at all!" Qin Zhiyuan did not hesitate to praise.

"Haha, it's easy to use, Qin, give me another amount of money, I can make a better one, I already have an idea, if I can solve the cooling problem of the engine, then I can increase the number of cylinders, and then improve the efficiency of the engine, which requires more experiments." Long Chengyuan's request sounded reasonable.

"Don't worry, I have a way to solve this problem, just add a small thing, and the problem of cooling will be solved." Qin Zhiyuan has an idea.

The problem of heat dissipation that restricts the development of in-line engines is solved, but this problem was solved after the appearance of engine fairings. The fairing is the technology of the British, and it first appeared during the First World War, Qin Zhiyuan doesn't know if the British have designed the fairing now, but since the accumulation of science and technology has reached this level, it doesn't make much sense to hide it.

"Really? Tell me about it. Long couldn't help but be curious, he was sensitive to technological advances, which is a necessary quality for a good designer.

"Okay, I'll tell you later." Qin Zhiyuan took off his helmet and stuffed it to Long Chengyuan, and picked up Giraldin, who ran over to greet him: "Jiji, are you good today?" ”

"Qin, don't ask me such a naïve question." Girardin blackfaced.

Girardin's language is progressing rapidly, and this sentence is actually spoken in Chinese!

"Qin, I have a new discovery here, when using aluminum, iron and copper to add trace elements, after special treatment, a kind of alloy aluminum can be obtained. This material is light and strong, and it is very suitable for use in aircraft, and if this metal is used to make aircraft, the performance of the aircraft can be improved by 50% on the basis of the current one. Think about it, Qin, building a steel plant, even if it is only used to sell materials, it will be enough to support the construction of Thunder City. Long Chengxuan muttered on the side.

"You don't have to worry about this, it's my responsibility to spend money, and your task is to spend money." Qin Zhiyuan is generous.

Aluminum alloy is a very widely used material, and the emergence of each alloy requires a lot of experiments, and it is impossible to talk about it without abundant financial resources as support. Long Chengxuan was afraid that Qin Zhiyuan's capital chain here would be broken, so his research would be unsustainable.

Qin Zhiyuan is not worried, with the development of the umbrella company's business, Qin Zhiyuan has a lot of income in his hands, and the income and expenditure are basically balanced. For Qin Zhiyuan, the penicillin that Sandy is researching is the golden mountain, and as long as the results of penicillin research are made, Qin Zhiyuan will only rely on the profits generated by penicillin, which is enough to support the construction of Corsica.

You know, when penicillin first appeared, it was sold for a high price of $10,000, so the penicillin factory is the factory that prints dollars, and it is a large denomination of $10,000, which is much more powerful than the Federal Reserve.

In order to make it easier for Long Chengxuan to conduct research, Qin Zhiyuan installed a small steelmaking furnace in Long Chengxuan's laboratory, which could be used by Long Chengxuan for testing.

The results of the experiment, of course, are still kept secret, and these things will definitely be produced later, but definitely not in Corsica, but in the land of China in the Far East.
