"The temporary solution was to equip the BF-109 with engines that could perform at an altitude of 11,000 meters. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 "The aircraft is codenamed the BF-109H and has an improved aerodynamic shape and increased lift compared to other models of the BF-109, as well as a specially designed supercharger and injection combustion support. ”

The air at high altitude is thin, and the output of the engine without a special supercharger will drop rapidly at an altitude of 10,000 meters. In order to increase the lift of the aircraft, the aerodynamic shape of course must also be modified accordingly.

In addition, because Germany has a leading edge in the fuel injection system, it has developed an injection combustion support device that "drugs" the engine, and temporarily increases the power of the engine by injecting water and ethanol (at the cost of shortening the life of the engine). This method is now also used on the BF-109H.

However, there must be a disadvantage, the supercharger that can fly high altitude is not easy to use at medium and low altitudes, and the aerodynamic shape that focuses on lift is often not conducive to flexibility. Therefore, this BF-109H is a dedicated high-altitude interceptor, and it will not be able to exert its power when it is at high altitude.

But there is nothing about it, and the planes of the World War II era were divided into high altitude and low altitude. However, the BF-109H can change the pneumatics and the supercharger of the engine, but it can't change the problem of small and short legs. Because this plane is already small, the fuel it can carry is naturally limited. Moreover, the supercharger suitable for high altitude is often heavier and larger, which is even more disadvantageous for increasing the range.

The range was too small, not only did the BF-109H act as a high-altitude escort aircraft to cover the German high-altitude bombers to counterattack the British, but also limited its cover range and airtime stay, so this was only a temporary solution.

"There are two final settlements," Marshal Kesselring continued, "and one is the jet scheme. The suction method of turbojet engine is different from that of piston engine, and it is easier to adapt to high oxygen deficiency environment. Jets are also much faster than piston planes, making them an ideal solution. We currently have 2 jet aircraft that are already in the prototype stage, belonging to Messerschmitt and Heinkel. Among them, the prototype of Heinkel is progressing relatively quickly, and it can be tested in April at the latest. The jet engine jointly developed by BMW and Fokker used by Messerschmitt has not yet been completed, so the first flight may have to be postponed until the end of the year. ”

Heinkel's program is the HE-280, which is progressing relatively quickly, and there are already engines. And the Messerschmitt company's solution is the famous ME-262. Because the strength of the Messerschmitt company cannot be compared with the Heinkel company, it does not have its own engine, so although the prototype was built, there is no engine to use for the time being.

"As for the second option, it is Fokker's turbocharged engine solution." Marshal Kesselring said, "The turbocharger developed by Fokker has been successfully tested on the Fokker D31 aircraft. However, the Fokker D31 was too big and bulky to be a bomber rather than a fighter. Therefore, the technical experts of the Air Force suggested that the Fokker turbocharger be integrated into the FW-190, but the FW-190 fuselage was too short to fit the Fokker turbocharger, so it needed to be greatly improved, which should be completed by the end of the year. ”

The Luftwaffe liked the FW-190 so much that it almost regarded it as a "treasure of air combat" and looked down on other new piston aircraft. However, they also have a reason to do this, after all, too many models are not conducive to mass production.

According to Marshal Kesselring's plan, in the future, the Luftwaffe fighters will transition to the Fokker Zero for medium and low altitudes and the FW-190 series for high and medium altitude (different sub-series need to be used to hit different altitudes), and the jet fighter will act as the final killer combination.

In addition, the Luftwaffe and naval aviation are now proposing to convert the FW-190 into fighter-bombers and carrier-based aircraft. There are even plans to continue the improvement of the FW-190 into a "final scenario" of a piston fighter.

"How many BF-109Hs are ready now?"

What the Anglo-American idea is, Hersman can probably guess. Now that the situation in the Mediterranean is urgent, the dignified array cannot be defeated. So they wanted to fight Germany by slaughtering civilians and at the same time frighten the people of Europe.

"There are currently 10 squadrons ready, and another five squadrons are being trained for high-altitude operations and will be ready for combat by the end of February at the latest."

Hersman nodded, relieved. 15 squadrons are 240 Bf-109Hs that can be put into operation, and if there are not too many B-17s that come to attack, they can cope with it.

And Germany will not only be beaten but not counterattacked, now Fokker has successfully developed a turbocharger, BMW has an 18-cylinder BMW802, and high-altitude and high-speed bombers are not a problem for Germany.

As long as the Middle East is taken and there is enough supply of oil and non-ferrous metals, whether it is a bombing game or a direct landing, it can solve the small trouble of hindering European integration in Britain itself.

As for how the United States, the final big boss, will be cleaned up, it depends on whether Japan is willing to cooperate or not -- this time, the invitation letter issued by Italy inviting the Japanese military observer group to come here, with Hersman's intervention, specifically indicated that it would invite Isoroku Yamamoto, commander of the Combined Fleet, to come. In addition, Hersman wrote a personal letter to the Japanese Minister of the Navy and Shiro Kawako, describing the air raids on Scapa Bay and the naval battles in the eastern Mediterranean.

……

Kure Gungang, the flagship of the combined fleet of the Japanese Navy "Nagato".

After receiving the invitation letter from the Italian embassy and Hersmann's handwritten letter, Admiral Kazukawa Koshiro immediately sent his vice-minister, Sadajiro Toyoda, to arrive at the "Nagato" anchored at Kure's port with Hersmann's letter.

Hersmann's letter was written in English, and the officers of the Japanese Navy were all proficient in English and could read without translation.

Yamamoto Fifty-six read it very carefully, reading it word by word twice, before gently placing the letter on his desk.

"Yamamoto-kun, this German field marshal also proposed a sneak attack on Pearl Harbor, which coincides with your suggestion to the Admiral of Kagawa on January 7."

Sadajiro Toyoda looked at Yamamoto, who frowned slightly, and said with a smile.

He was also a pro-German element in the Japanese Navy. Japan also had a part of the credit for joining the German-Italian steel alliance in September '40.

Inspired by the bombing of Scapa Bay and the Toulon incident, Yamamoto began to envision a surprise attack on Pearl Harbor, and on January 7 he wrote to the Secretary of the Navy Kazukawa proposing the idea of a surprise attack on Pearl Harbor.

"Field Marshal Hersman came up with the same idea, and he also carried out a successful surprise attack...... "Yamamoto Isoroku smiled bitterly, "maybe someone in the United States would think of the same way?" ”

"Yamamoto-kun," said Sadajiro Toyoda, smiling, "the United States does not have Zeros, and their naval training is so lax that they can't compare to us." The air attack on Pearl Harbor will certainly succeed regardless of whether or not a surprise attack can be achieved. ”

Yamamoto fifty-six nodded. Sadajiro Toyoda is right when he says that the US Navy is more lax now...... No, it should be said that the whole United States is relatively lax, so the surprise attack can most likely be successful.

But even if it succeeds in a surprise attack on Pearl Harbor and paralyzes the Pacific Fleet, it will at most give Japan a strategic window of six to 12 months. Whether or not to win after that, in Yamamoto's opinion, is not something that Japan can fight.

It's up to Germany to fight! If Germany were defeated by Britain and the United States, Japan would not be able to defeat it by any means.

However, judging from the current situation in the European theater, it seems that Germany will be victorious.

"As long as Germany can conquer the Middle East," said Sadajiro Toyoda, "our empire will take Singapore and open up Malacca, and then the two sides will be able to join India." The German-Japanese-Italian steel alliance will be undefeated! ”

He paused, and then said, "Therefore, Minister Kagawa hopes that Yamamoto-kun will go to Italy in person and discuss the matter of joint operations with Marshal Hersmann. ”

Yamamoto Fifty-six glanced at Toyota, in fact, he knew that Kagawa Koshiro was not in charge, and the Admiralty was actually the vice minister of Toyoda Sadajiro. Therefore, it was Toyota himself who wanted him to go to Europe to meet Hersman.

"Then what does Minister Kagawa want to ask the Germans?" Yamamoto Fifty-six knew that Toyota was coming in person, and it must be "face-to-face teaching". However, Toyota's qualifications are not as good as Yamamoto's, and his military rank is one level lower, so naturally he has to speak in the name of Minister Chuan.

Seeing Yamamoto hand over the steps, Sadajiro Toyoda smiled and said, "There are some conditions, and Minister Kagawa hopes that Germany can provide the technology of the JU88 bomber...... This aircraft is very powerful in ship attacks and can carry out dive bombing at an angle of 60 degrees. If the Imperial Navy can be equipped in large quantities, it will be conducive to the establishment of a defensive circle against the United States.

Second, Minister Kazukawa also hopes to jointly develop the next-generation model of the Zero fighter and the Type 99 shipblast with Germany. It was also hoped that Germany would transfer to us the most advanced engine technology, which was necessary for the Reich to sustain a protracted war.

Third, Minister Kazukawa also hoped that the German side would send some ace pilots with actual combat experience to Japan as instructors so that we could conduct intensive training for our carrier-based pilots. It would be better to allow Japanese carrier-based aircraft pilots to fully understand real air combat and the characteristics of Anglo-American fighters before going into battle.

Finally, Minister Kazukawa also wanted to engage with the German side on the Dutch East Indies issue...... The oil of the Dutch East Indies was necessary for the Empire, and if it could not be obtained, then the Empire would not be able to go to war. (To be continued.) )
