The Rise of the Empire

"Hello, this is the best wood engineer in Germany - Mr. Heliward. He has a lot of research on all kinds of wood in the world, and he is proficient in woodworking and the production of various boards. He also has a good understanding of various glues. For this reason, we decided to hire him as the designer of our aircraft wooden parts." Sir Daimler personally introduced this Mr. carpenter with gray hair to the prince. No, it's called wood accessories designer now. \u003c/p\u003e"Well, very good." The prince said calmly, then took a step forward, and stretched out his hand to show respect for the other party. What happened to the carpenter? Who told you that carpenters can't be high-tech? Before the end of World War II, wood was still one of the important raw materials for aircraft! Wooden airplanes made by skilled carpenters are called wooden miracles, such as the British mosquitoes. And the low-level ones are called flying firewood, such as the wooden planes of the Russians...  \u003c/p\u003eThe so-called subtlety sees kung fu. The background of an old industrial power is not only reflected in the big aspects such as engines and naval guns, but also very nb in the subtleties. Which country did not get a wooden plane in World War II ? But why is it only the DH98 Mosquito bomber that created such a great reputation? Didn't the Germans also engage in ta154? You try to get a plane that is mostly wood. It is certain that it can come out, but the quality problem is hard to say. \u003c/p\u003eAnd in the environment of World War I, the scale of electrolytic aluminum is still very limited, and the bulk of the aircraft is still wood! If you change his name, this Mr. Heliward will immediately look taller, such as an expert in aerospace materials! Is this name domineering? But before World War 1, this material specialist was no different from a carpenter.... \u003c/p\u003eI really thought it would be enough to find two pieces of wood, look at the texture, and then see if there are any moths? At most, you are working on two plywood boards together? What international joke? Your production is Aviator 1, right? Aviation is a sophisticated and high-end industry, and every job is extremely complicated, even wood processing. But this time, the prince really saw how powerful a top carpenter really is! To paraphrase a saying from later generations, it is called the number one scholar. After seeing this plane, Germany has the hope of making its own mosquito! \u003c/p\u003e"According to Mr. Daimler's requirements, and my many years of experience, wood materials can only be used for those parts of plane stress. Because the effect of wood itself on twisting and shear stress is not good, this It is an unavoidable weakness, so the landing gear, engine, the installation point of the control wing surface and all the parts involving three-dimensional stress should use metal materials instead of wood."\u003c/p\u003e "And in other parts of the production machine When it comes to the body, the wood we need to use cannot be a single laminated board material, just as steel-faced iron armor and hardened armor can improve the strength of the armor through steel plates with different physical properties, the wood we use must also be multi-layer wood. The outer layer should be strong, so we use high-strength plywood material, and the inner should be strong, so we use the wood core of certain trees as material."\u003c/p\u003e"Based on my many years of experience, the outer material should be chosen Canadian birch or North American spruce, especially the latter, are the best materials. This kind of tree is very hard and dense, and has little resin. It is suitable for industrial processing. The grain is fine and straight, and it is easy to paint. Moreover, the wood is tight and has good nailing force on nails and screws! What's more commendable is that even in a relatively humid environment, its moisture deformation is very uniform and it is not easy to crack."\u003c/p\u003e "Then choose Spruce, it’s more convenient to get it from the Americans, the prince thought for a while and said.”\u003c/p\u003e “As for the inner material, I plan to use Ecuadorian balsa wood (also called balsa wood). I will use plywood made of spruce wood core to reinforce the joint between the fuselage and the bulkhead.

Of course, this is just a matter of materials. Before making the frame, we need to make a model with mahogany or concrete male mold, then put various parts into it, fix it with special glue, and then reinforce it with leather strips, and wait until it is completely cured After that, we remove the strips again. "\u003c/p\u003e"According to my superficial understanding of woodworking, if the aircraft body is in a wet state, the use of the wood you just mentioned will not be affected much, but ordinary glue may not work, right? This would be a disaster for the aircraft if it resulted in degumming. "As a time traveler, His Royal Highness the Prince did not forget to show off his meager knowledge at this time!\u003c/p\u003e"You are right, the easiest way is to seal the joint with a whole piece of plywood , in order to reduce the erosion of water vapor, and we can also use a special urea-formaldehyde resin glue to increase the bonding strength. Mr. Heliward nodded and said.\u003c/p\u003e "Fuck, let people live?" This guy even knows this stuff? "As an aviation enthusiast, the prince once read a large number of documents about Mosquito aircraft in another dimension. When comparing the wooden aircraft of Germany and Britain, he mentioned a problem of glue, and began to use the aircraft adhesive for Mosquito Not the best choice. In 1944, when the Mosquito was deployed in large numbers in the Far East, there were many accidents due to degumming problems, and the German glue was not good. Until later, a urea-formaldehyde resin called "Meteorite" was used. This problem was completely solved after glue. What I didn’t expect is that in this plane, some people have noticed this problem in the first few years of the 20th century...\u003c/p\u003e “Everything is according to what you said I hope that the wood you developed can be used in every aircraft of the Bavarian Air Force in the future. Don't worry about salary and treatment. You should have what Sir Daimler has. In addition, I would like to ask, is this material convenient for mass production? "The prince raised the last question.\u003c/p\u003e"This is a problem of mold processing and ideas. As long as the ideas are in place and the molds are in place, piano factories and furniture factories can produce these materials. And we have already used this new material to manufacture several prototypes, including a fighter jet and a twin-engine reconnaissance bomber. Sir Daimler replied. "These planes are lighter and stronger than all our previous planes." Especially twin-engine aircraft, it is more difficult to shoot down with ordinary machine gun bullets. We have conducted anti-strike experiments, and the latter was declared scrapped after being hit by more than 100 rounds of bullets. "\u003c/p\u003e "How is the integration of the aircraft's weapon system? "The prince thought for a while and asked again.\u003c/p\u003e"It has been completed. The new targeting equipment and bomb hangers have been successfully installed. Although we cannot guarantee the effect, we can at least guarantee that they can fight. "Sir Daimler said respectfully.\u003c/p\u003e"This will be the best news I heard in 1903. I want to see them right now. "The prince said.\u003c/p\u003e "As you wish, Your Highness. "Sir Daimler bowed and saluted.\u003c/p\u003eThanks to book friend Wang Yao for his young guard rabbit, fallen king, first guard tank brigade, happy army, slowly traveling k, blue bubble hot spring, sea you Side's\u003c/a\u003e~~~!
