"Finally, I would like to talk about the core of this rearmament of aviation -- the issue of engine development, which is what the Führer is most concerned about at the moment." After the specific models and orders were distributed, Speer said with a serious expression, "Judging from the recent technical exchanges with the Japanese side while copying and borrowing British and American engines, we have many misunderstandings in the field of engine development, and there are also many deficiencies in the field of basic materials science." Taking Mercedes-Benz DB601 series engine as an example, Japan copied a DB601Aa (German starting power 1175HP) on the basis of our technology authorization, and the power was only 770 horsepower when they first tested the machine, but Japanese experts quickly increased to 1200 horsepower by changing the production process and materials (the original DB601 is cast with aluminum-magnesium alloy, and Japan added nickel, manganese, molybdenum and other materials), and soon increased to 1200 horsepower. This time, Aichi provided the Atsuta engine horsepower only 50 horsepower behind us, and yesterday they submitted new drawings and materials showing that they have developed to 1500 horsepower - and we have abandoned the DB601 to develop the follow-up 603 series - let's see, with the Japanese technical ability, we can develop the DB601 to 1500 horsepower, but what about ourselves? ”

The technical representative of Mercedes-Benz has a very ugly face, although Minister Speer's words are harsh but do not exaggerate the facts, although the engine performance of the Japanese is not stable enough, and the trouble-free time is short, but the index is higher than that of Germany itself, and the Mercedes-Benz company itself designed the power of the DB601 offspring is only 1475 horsepower, but the trouble-free thing has to be divided into two things: many aircraft have been reimbursed long before the engine life is exhausted. Japan is still more cherished of aircraft, and the Russians' way is more simple and rude, and the trouble-free life of aircraft engines basically does not exceed 200 hours. And 80% of Soviet pilots were shot down before they flew 200 hours.

"BMW's situation is not much better, among the world's mainstream star 14-cylinder air-cooled engines, your weight is the heaviest at the same power level, and your power level is the lowest at the same weight level, and even the Japanese model is better than you."

"This ......" said that the American R2800 and R2600 are stronger than the BMW 801, BMW does not dare to refute, but the Japanese model is stronger than their own, they are not convinced, and the last time the "protection" engine drawings are not good?

Speer seemed to see his dissatisfaction. Shook over a brief technical parameters: "The Rong engine (lightweight and high-power engine) is already an example, and the technical indicators published in the drawings of the 'Mars' engine of the Japanese Mitsubishi Corporation, which were just obtained yesterday, are even more so, and the Japanese were going to use them in the transformation of the Tianshan attack aircraft." The engine has a maximum power of about 1,800 hp like the BMW801D, but it weighs almost 200 kg less than you. ”

"What? This is impossible" He took it unconvinced, but after looking at it, he broke out in a cold sweat, and finally refused to let go, as if he had received a treasure. "Our company took over this engine."

Dr. Tan Ke also leaned over to take a closer look. If the news is true, this lightweight air-cooled engine can be easily installed on the Fw-190A series, which is very beneficial to the performance of the aircraft - his biggest headache now is the engine problem.

"I've looked up the reason, I don't think that the empire's technology is backward, but there must be a problem in the empire's materials science research, and this lesson must be made up as soon as possible." Hoffman said sincerely, "That's why I've worked hard to enrich all kinds of resources and technologies." I hope that you will broaden your thinking and carefully digest and study the achievements of Japanese experts in the fields of materials science, aerodynamics, and engines. At the same time, learn from the achievements of the American R2800 and the British Merlin engine, use the improved process and materials to produce new engines, do not be afraid of lack of resources, and the Minister of Speer can get you any rare metal, but you must come up with the best products to tap the maximum potential of the existing models. ”

Historically, Germany has not been equipped with turbocharged engines during World War II, not because German technology can't get it, on the contrary, Germany has such forward-looking research, but because the foundation of materials science is not solid, rare metal resources are insufficient, especially the gap of superalloys is very large, resulting in turbocharging can only stay in the laboratory; Although Germany leads the world in the level of jet engines, due to the shortage of metal, the engine has a short trouble-free life. If this weakness can be improved, Germany's aviation strength will be stronger than it has been in history, and only by increasing its aviation strength can Germany's final victory be guaranteed - regardless of air superiority, the German ground forces are completely unafraid of any enemy, and can still have a large upper hand in the face of British and American forces on the Western Front.

"Aviation experts of the Ministry of Armaments believe that our liquid-cooled engines are not far from the world's advanced level, but the gap between air-cooled engines is relatively large, which is related to the fact that we are more concerned about liquid-cooled engines and only one air-cooled engine company, so special attention must be paid to the air-cooled series." Before the war, Germany had two main companies that mainly produced air-cooled engines, BMW and Bramo, but later BMW acquired Bramo, and as a result, only one high-power air-cooled aero engine remained.

"In view of the current actual situation, the Ministry of Armaments has decided to make the following adjustments." Speer glanced majestically around the venue, "The BMW-Bramo-Fiat Joint Aero Engine Design Bureau was formed and directly under the Ministry of Armaments, of which the BMW group focused on the follow-up development of the BMW 801 and the mastery of the R2800 technology, while the Brammo-Fiat carried out the joint development - their leading direction was the restoration and imitation of the air-cooled engine provided by Japan, Italian experts would share their technical know-how, and Japanese engine experts would also participate in these projects; On the other hand, we will send experts to Japan to help them upgrade and exchange their liquid cooling and jet engine technologies. ”

The last one is obviously a necessary condition, and without reciprocal technology exchange and exchange, Japan will not be foolish enough to come up with its latest and best aviation technology. However, in the field of aviation, there is still room for mutual exchange between Japan and Germany, and in the field of tanks and artillery, Germany is absolutely crushed, and Japan will have to pay for all this with precious metals or raw materials in the end, and Germany will still be in a dominant and advantageous position.

"The adjustment of interests, patent licensing, and funding allocation involved among the allies are all in the hands of the Ministry of Armaments, and on the whole the companies will not suffer losses, and the Ministry of Armaments has also prepared 300 million to 500 million Reichsmarks for joint development, and the development costs for the companies are paid, which can be regarded as preliminary compensation for the adjustment of interests." Hoffman concluded, "We must take a long-term view, because if we win the war, the whole of Europe will be in our hands, and it will not be a problem to authorize or collect money as we want, but if we lose, all our achievements, talents, equipment, and factories will become the enemy's spoils of war - this is a very terrible thing and must not happen." All design bureaus and manufacturers must obey the unified dispatch and arrangement of the Ministry of Armaments, open technical barriers to each other, and do not allow any acts of resistance and sabotage regardless of the overall situation -- that is treason! ”

The word "treason" blew like a gust of cold wind, and everyone's hearts trembled, and they subconsciously shrank their necks -- the Führer is not joking, and the last time the mastermind of the treasonous group, including a bunch of marshals and generals, was hanged by a bunch of marshals and generals.

"In 1943, the focus was on increasing the production of aircraft engines as much as possible, and in addition to our own production needs, the demand for our engines in Japan, Italy, and other countries would also increase on a large scale. At the same time, the main aircraft factories will go to Italy to distribute production, and the relevant cooperation list and docking companies will be arranged by the Ministry of Armaments, and we will first realize the unification of air force equipment in the Italian direction, and some unimportant and low-demand accessories will be arranged for production by other enterprises in the country and companies in France, Belgium, the Netherlands and other countries as much as possible. Speer finally told them, "After the reorganization and adjustment, the production capacity of the Reich's tanks has been doubled, and it is expected to increase to three times next year, plus the output of Italy is estimated to be four times or more, and it is expected to reach 35,000 units per year, and I hope that aircraft manufacturing will also have room for such improvement." The initial production target for the first half of next year is 2,500 aircraft a month, and the annual requirement is to exceed 40,000 aircraft, plus more than 10,000 aircraft in the Italian direction, and at least 50,000 aircraft will be produced a year. ”

Looking at the people who were stunned by this number, Hoffman told them: "Don't think that 50,000 is a lot, the United States alone can produce more than 60,000 planes next year, and if you add the production of Britain and the Soviet Union, their number may be twice as much as ours -- if it weren't for the courage of our air force heroes, we would have been overwhelmed by American planes a long time ago." ”

The representatives of various companies stood up one by one and expressed their willingness to firmly support the adjustment and reform of the Ministry of Armaments, and resolutely cooperate with His Excellency Speer's decision to invest in production in Italy.

After the meeting, Speer quietly asked Hoffman: "Führer, are you really ready to produce so many aircraft, especially fighters?" ”

"Of course, you haven't seen the horror of Anglo-American strategic bombing, I must have a sufficient number of aircraft to cope with all this, the cost of manufacturing a 4-engine heavy bomber is about 20 Bf-109s, 7-8 Fw-190s, Britain and the United States may have 2-3 times our strength, but do you think their national strength can be 7-8 times stronger than ours?"

"Of course it's impossible......," Speer thought to himself, and if that was the case, he would simply stop fighting and surrender as soon as possible. (To be continued.) )
