~I wish you all a happy New Year!

Military revenge on the German Empire, submarine secret warfare is the most secretive and effective.

In addition, the Chinese imperialists also provided Li Weiguo with other military retaliation methods.

The Chinese Empire's navy will set up control throughout the North Atlantic in the name of attacking pirates and catching murderers, specifically intercepting and searching the merchant ships of the German Empire. If necessary, they can be seized and forced the German Empire to fight a diplomatic war with the Chinese Empire. As long as the German Empire does not have the strength and confidence to go to war with the Chinese Empire, they will choose to endure.

In addition to the Chinese Navy, the Shence Army and the Air Force will also take action.

However, unlike the navy's mode of action, the army and the air force will increase the number of troops garrisons around the German Empire. For those European countries in a swing state, the Chinese Empire will force them to agree to let the Shen Ce Army enter in a tough manner. As long as the Shen Ce Army enters and has a military base, these swing European countries will have to stand in the camp of the Chinese Empire and choose to confront the German Empire.

In addition to increasing the scale of European garrisons, bombers have also begun to be put into service in batches.

Since the British incident, the aircraft carrier battle group of the German Empire High Seas Fleet deployed bombers for the first time. Although the bombers were shot down by the powerful air defense firepower net of the Imperial Navy's Atlantic Fleet at that time, it shocked the entire Imperial Navy's top leaders.

Bombers can threaten the naval fleet, which attracted the high attention of the senior management of the Imperial Army. In addition, Li Weiguo's deliberate guidance, so after the English Channel incident, the Imperial Army accelerated the development of bombers and began to carry out related tests on the naval aircraft carrier.

Since Hitra no longer played according to common sense, Li Weiguo had to change his tactics. In order to deal with the fighter jets and bombers that appeared in advance in the German Empire, at the instruction of Li Weiguo, the Imperial Academy of Sciences lifted the confidentiality level of some sealed technical materials and handed them over to the imperial side.

These sealed technologies were related research conducted by the Imperial Academy of Sciences under the order of Li Weiguo many years ago, and were all technical data related to aircraft.

At the beginning, Li Weiguo was worried that the application of advanced aircraft design concepts in later generations would seriously affect the historical process, but he did not want to be surpassed by other countries. Therefore, he ordered the Imperial Academy of Sciences to develop and reserve technology in advance and then seal it. Once the required suitable, it was ensured to be directly used, so that the Chinese Empire still maintained its technological advantage.

But as Hitra did not play according to common sense, Li Weiguo could not care about so much.

This time, the Imperial Academy of Sciences handed over technical information about aircraft to the military, all of which are the most advanced fighter technology and test data in the world.

However, these are all secrets, and the military does not know that the Imperial Academy of Sciences has long had these advanced fighter jet technologies.

For the Chinese Emperor's side, they didn't care about those, they only care about whether they could fight against advanced fighter jets in the hands of the enemy.

At present, the enemy of the Chinese Empire is very clear, that is, the German Empire, and the enemy of the Chinese Empire Air Force is naturally the German Empire Air Force.

Today's German Empire already has many models of fighter jets and bombers, and Hitra seems to be very attentive in this regard.

However, for the Chinese Empire, the most nervous ones were the German Empire's Fokker E3 fighter jets and the Gotha bombers.

According to the information mastered by SHIELD, the Luftwaffe's Fokker e3 fighter is much stronger than the Juncker fighter a few years ago. Its aircraft is 3 meters high, 8 meters long, and has a wingspan of 10 meters. It adopts a normal layout of mid-single wings, with a tight line, a small wingspan and a good maneuverability. The machine gun is installed on the upper part of the nose and is easy to aim and push and shoot. The maximum take-off weight is 800 kilograms, the maximum flight speed has also exceeded 180 kilometers per hour, the practical ceiling has also exceeded 3,500 meters, and the cruise time is 2 hours.

The Gotha bomber has a wingspan of 24 meters, a length of 13 meters, a height of 4.3 meters, and a weight of 4,000 kilograms. It uses an engine power of 4,190 horsepower, a maximum speed of 140 kilometers per hour, a ceiling of 6,500 meters, a range of 635 kilometers, and a weapon of 2 to 3 heavy machine guns, and 10 50 kilograms of eggs.

These two German fighter jets are the most tense and important to the Imperial Air Force of China.

When they obtained the technical and experimental data of fighter jets and bombers provided by the Imperial Academy of Sciences, they finally breathed a sigh of relief.

The Imperial Academy of Sciences has always been at the forefront of the world in aircraft research and development. The fighter and bomber data handed over to the Imperial Air Force are incomparable to all aspects of the Germans.

The first is the airfoil design. During the World War, aircraft enthusiasts from all over the world did not realize the impact of airfoil thickness on the wing structure. The traditional airfoil at that time was "upward protruding and concave" type, but under the technical and technological conditions at that time, such airfoils were extremely fragile in structure. If it was a monoplane, a large number of pillars and stretching lines were required to strengthen. Therefore, the monoplane at this time was not as good as biplane or even multiplane in terms of lift, strength, weight, etc.

Although Hitra also told the German aircraft designers that they would change the airplane wing design, it was a pity that the German Empire at that time did not have wind tunnel laboratories at all, and there was even less support for aerodynamic theory. So although Hitra was so exaggerating, it was a pity that German aircraft designers could not realize Hitra's idea because they lacked various experimental data to support it.

But the Chinese Empire was different. Li Weiguo had long ordered a special person to start the theoretical research of aerodynamics. This was never out of the blue. At the same time, he also built a wind tunnel laboratory, which allowed various theoretical research to be proved by laboratory.

This time, the Imperial Chinese Air Force obtained the design drawings of the new fighter.

According to the numbering rules, this time the fighter model is 17, which is used to replace the current 16.

In terms of layout of the 17 fighter, it is much more advanced than the German Foxconn e3 fighter. It mainly designs the lower surface of the airfoil as a straight surface, increases the thickness of the airfoil, improves the strength of the wing structure, and has very good maneuverability. It uses an inline air-cooled engine, which doubles the power of the liquid-cooled engine used by the Foxconn e3 fighter, making the take-off weight reach 1,200 kilograms. It can be installed with two heavy machine guns, increasing the number of ammunitions, and the maximum flight speed has exceeded 220 kilometers per hour, with a practical ceiling of 4,000 meters, and a cruise time of one hour is also one more than the Foxconn e3.

The Imperial Chinese Air Force was very excited after getting the design drawings of the 17 fighter jets, but advanced fighter jets always attract competition. When the Air Force got the 17 fighter jets, the Navy immediately reached out to ask for it. After all, the Navy also established a naval aviation force and even a naval aircraft carrier battle group, which was essential for carrier-based fighters.

So the 17 fighter jet was quickly modified and named it the 18 carrier-based fighter jet by the Navy.

From 17 fighter jets to 18 carrier-based fighter jets, this is just a matter of sea takeoff and sea landing, but there are many technologies involved.

One of them is static stability. This technology is currently only mastered by the Chinese Empire and is used on 18 carrier-based fighter jets.

As the name suggests, this static stability means that early aircraft were static and unstable. However, because its speed is low and is still within the range that the pilot's intuitive response can control, it does not require a complex control system. However, static instability gives the aircraft better agility and maneuverability.

For example, the German Empire also developed a stable fighter jet, which was a Juncker 9 fighter jet. Unfortunately, when fighting against the German Folk E3 fighter jet, it was easy to become a food on the Fokker fighter jet.

Therefore, the Luftwaffe once listed Juncker's aircraft as unpopular and purchased the Folk E3 fighter.

However, the 17 fighter jets obtained by the Imperial Chinese Air Force and the modified 18 fighter jets are also stable fighters, but there is no need to be afraid of being abused by the Folk e3 fighter jet.

This is because the new fighter jets of the Chinese Empire have exceeded 220 kilometers per hour in speed. At this speed, the static stability is very easy to control, but the static unstable fighter jets have become difficult to control.

When the Fokker e3 fighter is still at this speed, the pilot will find it difficult to control the aircraft to fight. Even if the aircraft is barely controlled, it will cause fatigue consumption to be too fast and it will be difficult to engage in long-term combat.

As the power of aircraft engines becomes larger and larger, the speed of future fighters will become faster and faster. Therefore, the German investment in the Folk e3 fighter is destined to be tragic.

The Imperial Chinese Air Force's 17 fighter jets and 18 fighter jets, and many other technologies surpass the Luftwaffe's Folk e3 fighter jets.

For example, the aileron problem. The aileron, one of the important aerodynamic control surfaces of the aircraft, gradually developed during the World War. The design idea at that time was very simple, and the purpose was to roll faster and the ailerons would be larger. But in fact, this large aileron seriously damaged the wing shape when deflected.

The Chinese Empire obtained data through wind tunnel tests to show that the rolling torque of the ailerons was not as large as expected, but it changed the drag distribution of the aircraft, so that when the pilot pressed the rod, the aircraft first produced yaw motion and then rolling motion. On the other hand, the lateral maneuvering torque required by large ailerons was also large. At that time, the aircraft were often statically unstable in both longitudinal and heading, and the maneuvering torque was extremely small. The imbalance of the three-axis control torque brought great difficulties to the pilot's maneuver.

Another huge advantage of the 17 fighter is the engine, which almost represents the highest aviation industry technical level in the Chinese Empire, directly leaving the Germans alone.

After the World War, the Chinese Empire and the German Empire became the two most powerful countries in the world, and both attached importance to the aviation industry, so they started to compete in aviation engines.

In the eyes of other countries, the Chinese Empire and Germany are both leaders in engine development.

Among them, the German Empire made outstanding achievements in cylinder engines, while the Chinese Empire has always been in the leading position in inline liquid-cooled and air-cooled engines.

In terms of engine propellers, even the Germans mainly used the layered wooden structure propellers invented by the Chinese Empire. At present, the focus of the development of engines around the world is to improve the power-to-weight ratio and reliability. The rotary cylinder engines of the German Empire have high heat dissipation efficiency and light weight, and developed rapidly during the World War. However, because all cylinders rotate around the axis, they will generate a great gyro torque, which seriously affects the operation of the aircraft. Therefore, after the World War, the German Emperor's side asked to replace the engine. The engine used on the Fokker e3 fighter was the inline liquid-cooled engine of the German Empire imitated the Chinese Empire. However, the German aircraft engine started late and could only copy the existing technology of the Chinese Empire.

On the contrary, despite the local overheating problem of the Chinese Empire, the relatively bulky inline engines, have great development potential, especially now that liquid cooling will be replaced with air cooling, which will become the mainstream of piston engines in the following decades.

However, compared with the fighter jets of the German Empire, the biggest technical advantage of the fighter jets of the Chinese Empire is the slat and slit flap technology

As early as during the World War, the Aviation Laboratory of the Imperial Academy of Sciences and the Wind Tunnel Laboratory of the Imperial Academy of Sciences discovered the slat lift effect respectively. That is, by slitting at the leading edge of the wing, the stall angle of attack of the wing and the maximum lift coefficient of the wing can be increased.

In the second year after the end of the World War, slat technology was first applied to wind tunnel test models. At that time, this design was mainly used to delay wingtip stall and improve the tail rotation characteristics of the aircraft. Later, after continuous improvement into the wingtip slat form, it also achieved good results, making the aircraft have good low-speed maneuverability.

However, at that time, Li Weiguo believed that this technology would change the historical process of fighter jets, so he issued an order to seal the data related to the wind tunnel test of the fighter jet model. Until now, it was handed over to the Imperial Chinese Air Force and used on 17 fighters and 18 fighters.

In fact, compared with the simple flaps commonly used at that time, the lifting performance was better, which helped to greatly improve the take-off and landing performance of the aircraft. Of course, the structural complexity and weight also increased accordingly.

To this end, the Imperial Academy of Sciences specially established a drag reduction research project. During the experiment, researchers discovered a laminar surface layer. This surface layer has the minimum friction resistance, which is the ideal effect that designers expect. However, due to the limitations in manufacturing processes, the wings require absolutely smoothness and no roughness and curvature, this requirement is difficult to achieve even in the 21st century. The ideal laminar surface layer has not been realized for decades since then.

After being rejected by Li Weiguo, the Imperial Academy of Sciences would not hang itself on a tree. Soon through the study of aircraft drag resistance, the designers at that time gradually formed two schools. One side believed that the improvements carried out for drag reduction will inevitably lead to an increase in the weight of the aircraft, thus offsetting the aerodynamic benefits brought by drag reduction. Therefore, the drag reduction design is not necessary. The result is that the appearance of the fighter aircraft design is very uneven and extremely ugly. The other side has the opposite view. The design attaches great importance to drag reduction. The aircraft has a streamlined appearance, so its performance benefits a lot.
