Professor Schmidt shrugged his shoulders, he didn't care, he was a foreign consultant after all, he could just ask, the wind tunnel in these years was worthless anyway, as for the vertical, arc and high-speed and the like have not yet come out, since the employer has money, just take the opportunity to carry out his own experiments.

Liu Yun didn't understand the wind tunnel test, but as soon as the German professor said, he immediately understood, isn't it the simulated flight provided by the brain, of course, the brain is more bullish, but unfortunately it cannot be promoted, so for the future aircraft research and development, the construction of wind tunnels is still very necessary.

For the construction of wind tunnels and aircraft research and development, they hit it off, and immediately established the West Sichuan Aircraft Design Institute, selected 50 researchers from West Sichuan University, and transferred an engineer battalion from Maozhou City to be responsible for the construction of the research and development center.

When aircraft research and development and agricultural research were in full swing, Liu Yun left everyone's sight under the pretext of inspecting railways and cement factories, and hid in a secret base near western Sichuan to conduct his own training aircraft research, and planned to carry out a three-pronged approach, that is, light fighters, heavy fighters, and jet fighters.

In Professor Schmidt's vision, the fighter will use a new type of aviation material, a kind of aluminum alloy with high hardness and light weight, followed by a good aerodynamic layout, cancel the landing gear with wind resistance, etc., to be fully enclosed, and finally it is recommended to use a constant speed propeller and a large horizon cockpit.

Liu Yun has ant robots, it is not difficult to make duralumin alloy, the aerodynamic layout has been solved by Professor Schmidt, as for the landing gear and the like, it is easier to do, it is simple automatic control, and the brain can easily handle it, only the constant speed propeller and the large vision cockpit, he is a little unconscious.

Practice brings true knowledge, anyway, the reverse design data of the Zero fighter has been collected by the brain, and only needs to continue to simulate the flight, you can get the best answer, scientific experiments are like this, continuous repeated experiments, the process is still very lengthy, Liu Yun remembers the "dichlorvos" pesticide research and development, it was 666 experiments, he is aircraft research and development, it is not surprising that the experiment is 6666 times.

After hundreds of flight simulations, the effect of the large field of view cockpit came out, before the popularization of computers, the navigation and operation of the aircraft, all rely on visual vision to solve, so the greater the pilot's field of vision, the greater the probability of giving priority to the enemy, so the cockpit needs a special design.

After hundreds of take-off and landing simulations, Liu Yun understood the constant speed propeller, which was later the clutch of the car, why it was difficult for ordinary people to fly the plane, the problem was in the take-off and landing of the aircraft, according to aviation records, 80% of flight accidents occurred at the time of take-off and landing.

However, with a constant-speed propeller, the aircraft can fly at a constant speed in a certain gear, which is safe and fuel-efficient, and can also make everything clear to the pilot, such as the mid-speed gear when taking off, the high-speed gear when about to take off, the low-speed gear when flying, the lowest gear when landing, and so on.

With the more simulated flights, Liu Yun has a new understanding of the new Zero fighter, and he doesn't know whether the Japanese army's later Zero War is the fighter in front of him, with a length-to-width ratio of 3:4, a big head and a thin tail.

No matter what kind of aircraft, the engine is the primary problem, the reason why Liu Yun dared to engage in the super zero fighter, mainly because of the ants and the brain, early to get out of the 2200 horsepower engine, that is, the enlarged version of the Hawker Star engine, a single module is 1.2 meters square, placed on the aircraft, is bloated and ugly, but can not stand the powerful power, the comprehensive performance is outstanding.

Whether to directly create a super zero battle, Liu Yun is a little hesitant, even if it is really developed, at present, except for his own driving, others can not use it at all, it is estimated that the maximum speed will reach 750 kilometers per hour, which can take into account the dual advantages of low-altitude dog fighting and high-altitude dive acceleration.

The biggest problem is that the Super Zero is too good, and the requirements for pilots are also rising, just the intensity of the flight and frequent overloads can lead to the destruction of ordinary pilots, and Liu Yun wants to build excellent fighters, not excellent suicide planes.

By the way, Liu Yun suddenly remembered that in the early days of the Anti-Japanese War, the Hawker III fighter was already a little backward, but the Chinese pilots and the Japanese devils were still inseparable, and the devils finally relied on a war of attrition to gradually gain air supremacy, and it seems that the number of people is still very important.

If tens of thousands of pilots can be trained, even if the United States does not participate in the war, Huaxia can independently defeat the Japanese devils, of course, this is Liu Yun's personal fantasy, but in the thousands, it is still barely possible, and there are more than 1,000 cadets in the western Sichuan Air Force, depending on how high the success rate is.

The success rate of the cadets mainly depends on flight training, and the training depends on the trainer aircraft, so for the time being, the research and development of the trainer aircraft is the top priority, and after the manufacturing is successful, it is too wasteful to use it only for the Air Force Academy.

Can it really be done, those warlords are so honest, you can do whatever you ask them to do, they are too temperamental, Liu Yun was hesitating, and suddenly remembered the Red Army cadets, they are known for their poverty, and they all want to establish the Red Air Force.

Therefore, the trainer aircraft is not a pure trainer aircraft, but a fighter aircraft that can take into account combat, suddenly, Liu Yun pushed open a new door, the idea is becoming clearer and clearer, all kinds of inspiration is like a spring, a Hawker III. costs more than 20,000 US dollars, so the fighter can not be too expensive, the price of 10,000 US dollars is the best, of course, if it is exchanged for gold, it is more than ten or twenty kilograms.

With the new Zero Combat as the template, with the assistance of the Zhi Brain, Liu Yun has simplified the processing to form the Q version of the Zero Fighter, with a wingspan of 10.8 meters and a total length of 8 meters, using a modular star engine, with a size of 1.2 meters square, an output of 750 horsepower, and three constant speeds.

This type of fighter has a crew of 2 people, an empty weight of 1.5 tons, a maximum speed of 450 kilometers per hour, a cruising speed of 280 kilometers per hour, a minimum speed of 180 kilometers, a practical ceiling of 8000 meters, a theoretical range of 1300 kilometers, and two 12.7 mm caliber machine guns and two 60 kg bombs.

Processed by ant robots, it was quickly manufactured, looking at this newly baked aircraft, Liu Yun was more satisfied, and decided to name it Jianjiao I., and the comprehensive performance of the Hawker III., although it is not as good as the real Zero fighter, but it is also slightly better than all the current active fighters of the Japanese army.

Such an excellent aircraft, of course, to fly in person, Liu Yun only flew a few laps, and found that the Jianjiao aircraft is extremely simple, practical and easy to operate, just follow the flight rules to do, as long as you have driven a car before, then you can definitely fly it into the air, and can land safely.

Didn't say it, let the ant robot go all out to produce a hundred as soon as possible, Liu Yun himself hurriedly wrote the pilot's rules, fortunately, the planes in this era are very simple, and there are not many instruments, only such as wireless communication, flight altimeter and fuel display table, in addition, it should be noted that the problem of take-off, landing and visual flight, so the junior pilot is easy to write.

As soon as the pilots finished compiling the compilation, Liu Yun ordered people to reprint it overnight, striving to let the flight students have a copy, and demanded that within three days, they must memorize it backwards, otherwise they would be disqualified from flight training.

Considering that the students are all rookies, only twelve planes are allowed to take off at a time, and the flight time must not exceed one hour, and Liu Yun does not dare to let them fly directly, but according to the old rules, he secretly places an ant before liftoff to prevent flight accidents.

In a short period of 10 days, not only in the surrounding areas of western Sichuan County and Maozhou City, but even as far away as Fucheng and Chengdu, there were several rounds of air-skimming planes every day, causing serious uneasiness among the broad masses of the people.

However, the oil reserves have been in an emergency, not only the oil transported through the Fujiang River has been exhausted, but also most of the oil collected by the ants has been used, Liu Yun is also dumbfounded, these thousands of tons of oil are too useless, but nearly 100 flights a day, where can the fuel consumption be small.

In desperation, Liu Yun issued an emergency no-fly order, which made the students who had just felt it complain, and Commander Liu had to make two preparations, while placing orders with foreign oil companies and asking them to find a way to deliver oil to Fucheng or western Sichuan, and on the other hand, let the ants collectively go out to look for oil mines.

For the ideological work of the students, Liu Yun personally went to do it, one is to explain the reason for the ban on flying, and the other is to mobilize the students to find a way, clearly saying that as long as the fuel problem can be solved, they can fly however they want, but at present, they have to stop flying, and it is recommended that the students be patient for the time being.

Air Force cadets are carefully selected, knowledge and physique are the best choice, most of them come from wealthy families, after learning of the fuel dilemma, widely mobilized their families to send them fuel, and regardless of the cost, it is estimated that after having flight experience, they have already eaten the essence.

For this kind of crazy energy, Liu Yun neither supports nor opposes, he has already thought about the way to make oil, no matter how rich and powerful the families of these students are, they will definitely not be much better, so it is destined to be a farce, but he just doesn't want to dampen their passion for training.

He remembers that on the edge of the Sichuan Basin, there are some small oil fields and small gas mines, which seem to be in the area from Fucheng to Deyang, so he had to find it in person, if he is lucky, he can solve the current urgent need.

In addition, it is to replenish fuel in other places, especially once the Three Gorges of the Yangtze River crosses the Yangtze River and enters the open area of the Yangtze River, which is within the transportation range of large oil tankers, so Liu Yun imagines that if flight training anchorage points can be set up in Chengdu, Chongqing, Wuhan, Nanjing and other places, there is no need to worry about insufficient fuel for flight training.

Liu Yun has not yet thought about how to replenish fuel in other places, but no matter what, western Sichuan must reserve a large amount of oil, not to mention the training of students, it is said that once a full-scale war of resistance breaks out in the future, the rear will be severely blocked by the Japanese army, and if there is not enough fuel, no matter how many planes there are, it will be in vain.

How do you get oil? Due to the existence of the Three Gorges of the Yangtze River, the Yangtze River shipping is better than nothing, fortunately it can be continuously transported, the number and scale do not count on, and the other is to open the Yunnan-Myanmar transportation line, if the railway can be opened, the oil of Yangon Port can go directly to Sichuan, but in a short period of time, these ideas should be no fun.
