The principle of axial flow turbojet is simple, I roughly drew a structural diagram, the intake duct, the stator and blades of the compressor and the rotor blade diagram, the combustion chamber and the turbine three main parts and a shaft that threads the three parts together.

Samuel looked at it for a long time and said, "Mr. Li, I know the meaning of axial flow, and there is no problem with the principle at all!" The problem is the same as the previous one, that is, the speed will reach a height, so that the material is no longer able to meet the high temperature conditions to ensure performance. Samuel shook his head, looking regretful.

"Mr. Samuel, then we'll find a way to control the rotation!" I extended the axis of the figure just now, drew a schematic diagram of the reducer, plus a schematic diagram of the propeller, and wrote 1000 revolutions per minute next to the propeller. Push it to him! (Tribute to Mr. Jacob Jandrask)

Samuel was immediately interested! The window paper was pierced and it lit up, but the bend turned a little wider, and suddenly it went back from jet power mode to propeller mode. Samuel looked at the picture for a while, and then tossed it contemplatively. Finally, he nodded and said, "Mr. Li, it's definitely worth trying, but Mr. still has to be prepared to fail, and the cost may not be low." ”

"Mr. Samuel, how much time and cost do you estimate?"

"At least half a year, at least $100,000 or more." $100,000 is not a small amount, Douglas is developing the DC-3 aircraft, and one of the airlines is only offering $10,000, of course, they are supposed to develop a new aircraft to compete with Boeing.

"Good! Mr. Samuel, I will prepare 150,000 US dollars for you, and you will organize the research and development, and I will arrange for the factory to fully cooperate with you. But I'm going to understand each process and progress based on it. ”

Later, I made it very clear that one is to use kerosene as fuel; the second is to calculate the power of 2000 horsepower as the basic specification of development; The third is the design idea of heat insulation. Tell him as much as you can so that you don't waste time on these things.

With the development of the research and development work, his own work mode has become a handshake and supervision. On the one hand, I kept in touch with my uncle and learned about all aspects of the situation, and on the other hand, I kept in touch with Isaac and learned about the dynamics in the United States.

Samuel was busy with design calculations and structural design for a month, looking at the design drawings by himself, trying to think about some of the previous pictures and principle introductions, and remembered that there was a way to use air flow to reverse the heat insulation, but the structure would be much more complicated. An aircraft engine is a system engineering, and it is not something that can be made by looking at a picture; It is the accumulation of theories and the support of the industrial base for ideas that are fundamental. There is often a material that you don't have, or a truth you don't know, and you don't even have the qualifications to imitate; If your theoretical height and industrial base are not worse than others, then it is simple, only a glance, a sudden realization of things.

This was even more evident in Stephen, who was flying into the sky in just three months. There are aluminum alloy materials and manufacturers, and there are high-strength canvases made of chemical fibers. The delta wing has good gliding ability, and there are generally no casualties unless it is not able to do so in bad weather. I bought 5 trainer planes and started flying, and I even went up to have a good time. Han Ping continued training with 45 trainees, and a total of more than 80 people came from China and the United States, and nearly half of them were directly eliminated by the instructors, and it was clear that it would be good if half of the rest could come out. As long as you are on the farm, there is no problem with your own safety, and Dawu and a few bodyguards are also happy to see the hunt, and they have to try everything; Dawu's housekeeping skills have not grown at all.

Steve's vehicle modification was not a problem, and the first thing that came out was already a special vehicle for the farm. Stephen also has a dedicated cross-country track that offers cross-country training and a cross-country sports club.

I think it's a good base for training. After thinking about it, I arranged for my uncle to find 200 people from China to come to the base to learn aircraft repair and ground handling. Learn the technology of repairing and manufacturing automobiles, etc.; Learn radio repair and manufacturing. Arrange for two domestic college graduates to study in Samuel's group. Han Ping also put the training ground of the security company here, and he is now the boss of a security company with more than 400 people, and it is not good to let the family be a bodyguard anymore.

Looking at the engine test site, the sample shell was still broken by frequent breakage parts, and the more Samuel broke down, the more confident this guy became; I felt that I couldn't help much, and I was a little quiet.

Ask about the funding, the factory and Woody are well coordinated, there is no problem; Samuel is very expensive here, and it doesn't cost more than $50,000, and there's no problem. The difficulty is Steve, who built the airport runway, bought airplanes, hired coaches, made more than a dozen delta-wing planes, and was also responsible for the food and accommodation of so many people, and the club's income was basically a small amount, and he spent almost it, and gave him another $50,000 and ordered him to draw slowly. In this way, only 300,000 of the 800,000 remained, which was of no great use, and was remitted to Isaac to take it when needed.

I contacted my uncle, and Woody was going to take a trip to Europe in three months. A meeting time in New York was agreed.

I summoned the three responsible persons, asked if there was any situation, and briefly reported the matter of going to Europe. Stephen is the interim person in charge of things on St. Louis's side, and if there is anything that can't be solved, please ask your uncle. With Dawu, two American bodyguards and two elites arranged by Han Ping.

When I returned to New York, it was the end of April. Played with a few kids for a day, and bumped into a few core situations. Downer's firearms production has begun, about 150 per month, ask if you want to expand production, you think about it or think that you can maintain the current output, the core problem is that Donner continues to improve the guns that have been designed; Including semi-automatic and automatic rifles.

My uncle also talked about the overall situation in the United States, which can basically be carried out according to the plan; There were still some minor problems in China, but fortunately, the U.S. Consulate in Shanghai negotiated properly and there were no major problems; But it's already a signal. I don't have a good way to deal with this matter; I can only tell you to pay taxes in time, and you must not leave a handle in time, and it is estimated that some people in China will not have a good opportunity to speak for a while. The Nationalist Government's ability to tolerate foreigners is still admirable.

I was thinking about whether to take Xiaoya to Europe to have a look, but I was denied by Aunt Liu. Xiaoya, who knew the news, played tricks on her mother, and she also persuaded Aunt Liu to broaden her horizons and broaden her horizons. The angry Aunt Liu said, I am used to having problems and waiting to settle accounts with you!

Isaac came over to report the situation and informed each other, and Isaac became more and more like an expert. It has established its own reputation and social circle on Wall Street.

He discussed the development of drugs with Aunt Liu again, penicillin can be produced, and the yield will still be limited by the number of cultured seedlings. I don't think I'm in a hurry to put it into production, one is that we still need to leave time for sulfonamides to exert their earning power, and the other is the side effects of penicillin, which must be summed up through a large number of laboratory tests and clinical trials. Aunt Liu is no longer a pure technical expert, and she is paying more and more attention to business issues.

When I arrived at the New York factory, I saw the anti-tank guns of the products, and I also went to the shooting range to verify them. An exaggerated brake still played a decisive role, and according to Donner's parameters, the recoil was basically close to 20 kilograms. Dawu was interested in anti-tank and was very happy at the shooting range.

I'm still interested in the sniper type, and I don't know how many firearms I've played with in my previous life, but this kind of thing is only seen in it, and I haven't touched it! There is no problem at all with the range of some firearms reaching 2,000 meters, even with an 8x scope, it is still very difficult to deal with a target at 2,000 meters. One is that the accuracy of the gun is not enough, and the other is that the accuracy of the scope is not enough, but against a target of about 1200, there is no problem at your own level.

instructed Donner to continue to improve the sniper rifle, thicken the barrel, deepen the heat sink encryption, and reduce the added weight as much as possible; Find a way to process a batch of high-precision bullets, and the identification should not be mixed with ordinary anti-tank bullets. Scope to see if Germany can solve it.
