"Hello, this is the best wood engineer in Germany we hired - Mr. Heliward. He is very knowledgeable about all kinds of wood in the world, and is proficient in woodworking and the production of various boards. He also has unique insights into various glues and adhesives. For this reason, we decided to hire him as the designer of our plane wooden parts." Sir Daimler personally introduced this carpenter who is a bit gray in his head to the prince. No, he is now called a wooden accessories designer.

"Well, it's very good." The prince said calmly, then took a step forward and showed his respect for the other party. What's wrong with the carpenter? Who told you that carpenters cannot do high-tech? Before the end of World War II, wood was still one of the important raw materials for aircraft! Wooden aircraft made by carpenters with high levels is called wood miracle, such as British mosquitoes. And those made by low levels are called flying wood chopping, such as Russian wood aircraft......

The so-called subtleties are kung fu. The foundation of an old industrial power is not only reflected in major aspects such as engines and naval guns. It is also very nb in the subtleties. Which country did not build a wooden plane in 2 battles? But why is the DH98 mosquito bomber a family that has made a famous DH98 mosquito bomber? Didn’t the Germans also make a TA154? You try to build a plane that is mostly wood. It is certain to be able to come out, but the quality problem is hard to say.

Moreover, in the environment of World War 1, the scale of electrolytic aluminum is still very limited, and the big head of the aircraft is still wood! If you change the name, Mr. Heliward will immediately appear tall, such as an aviation materials expert! Is this name domineering? But before World War 1, this material expert was no different from a carpenter......

I really thought it would be enough to find two pieces of wood, look at the texture, and then see if there are any insects. At most, two pieces of pressed boards are working together? What an international joke? You are producing Flyer One, Aviation is a precision and high-end industry, and every job is extremely complicated, and even wood processing is like this. And this time, the prince really saw how powerful a top carpenter is! To put it in a later generation, it is said that every industry has the best prize. After seeing this plane, Germany has hope of creating its own mosquitoes!

"According to Mr. Daimler's request and my years of experience, the use of wood materials can only be used for those plane stress components. Because the wood itself has not good resistance to twisting and shear stress, this is an inevitable weakness. Therefore, the landing gear of the aircraft, the engine, the installation point of the control airfoil surface, and all components involving stereoscopic stress should be made of metal materials instead of wood."

"When other parts of the fuselage production, the wood we need to use cannot be a single pressed-ply material. Just as steel-surfaced iron armor and hardened armor can increase the strength of the armor through steel plates with different physical characteristics, the wood we use must also be multiple wood. The outer layer of the aircraft should be strong, so we use high-strength pressed-ply material, while the interior should be stoic, so we use the wood core of some trees as the material."

"According to my years of experience, the external material should be selected from Canadian birch or North American spruce trees, especially the latter, which is the best choice. This tree has a very strong and dense texture, and has very little resin. It is suitable for industrial processing. It has a fine and straight texture and is easy to paint. The wood is tight and has good nailing force on nails and screws! What is even more valuable is that even in relatively humid environments, its moisture deformation is very uniform and does not easily crack."

"Then choose spruce trees, which is more convenient to get from Americans, the prince thought about it and said."

"For the inner layer, I plan to use Ecuadorian light wood sandwich (also called barsamwood). And I will use plywood made of spruce core to reinforce the glue between the body and the partition. Of course, this is just a matter of material. Before making the frame, we also need to use mahogany or concrete mold to make a model, then put various parts into it, fix it with characteristic glue, and then reinforce it with a leather strip. After it is completely solidified, we will remove the leather strip."

"According to my brief understanding of carpenters, if the aircraft body is in a wet state, the use of the wood you just mentioned will not be too much affected, but ordinary glue may not work? If it causes degumming, it will be a disaster for the aircraft." His Highness, the prince, as a time traveler, did not forget to show off his meager knowledge at this time!

"You are right. The easiest way is to seal the glued area with a whole piece of pressed-piece to reduce the erosion of water vapor. At the same time, we can also use a special urea-formaldehyde resin glue to increase the strength of the glue." Mr. Heliward nodded and said.

"Damn it, will it still make people live? This guy even knows this thing?" As an aviation enthusiast, the prince once read a lot of documents about mosquito aircraft in another plane. In comparison with wooden planes in Germany and Britain, he mentioned a glue problem. The aircraft adhesive used for mosquitoes was not the best choice. In 1944, when mosquitoes were deployed in the Far East, many accidents occurred due to the degumming problem, and German glue was not good. It was not until later that a urea formaldehyde resin glue called "meteorite" was used to completely solve this problem. Unexpectedly, in this plane, someone had noticed this problem in the first few years of the 20th century...

"Everything is done as 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 issues. Sir Daimler has it, you should have it. In addition, I would like to ask, is this material easy to mass produce?" The prince asked the last question.

"This is a problem of mold processing and thinking. As long as the ideas are in place and the mold is in place, piano factories and furniture factories can produce these materials. And we have now made several prototypes with this new material, including a fighter and a twin-engine reconnaissance bomber." Sir Daimler, who was standing next to him, replied. "These aircraft are lighter and stronger than all of our previous aircraft. Especially twin-engine aircraft, which are more difficult to shoot down with ordinary machine gun bullets. We have conducted anti-strike experiments, and the latter was only declared scrapped after being hit by more than 100 bullets."

"How is the aircraft's weapon system integration?" the prince thought about it and asked again.

"It has been completed. The new aiming equipment and bomb mounts have been installed successfully. Although it cannot guarantee the effect, we can at least ensure that they can fight." Sir Daimler said respectfully.

"This will be the best news I've heard in 1903. I want to see them now," the prince said.

"As you wish, Your Highness." Sir Daimler bowed and saluted.
