Chapter 133 Methyl Methacrylate
In the next few days, with the help of Huang Zhefu, Zhao Tianyang continued to modify various problems of the aircraft.
"Okay, now that we have solved the problem of the tail wing vibration, it's almost ready to go!"
In the cave, Zhao Tianyang dropped the saw and jumped off the plane.
"What does Section Chief Zhao plan to name this plane?"
Huang Zhefu handed a towel to Zhao Tianyang and asked with a smile.
"As usual, Taihang Type 1 transport plane."
Zhao Tianyang took the towel and wiped the sweat from his head, then answered without hesitation.
"That's great!"
Huang Zhefu muttered to himself and said with a smile: "Since the aircraft has been tested, I think I should leave. There are students waiting for me at the flight school!"
"Having a plane without a pilot is not a good idea!"
Zhao Tianyang said: "This time when you go back, just drive this Taihang Type 1 transport plane back to Yan'an!"
“This…is not good!”
Huang Zhefu was a little tempted, but when he thought that this plane was the only one in the arsenal, he became a little hesitant.
"What's wrong with that?"
Zhao Tianyang acted indifferent: "Anyway, all the data that needs to be collected has been collected. We just need to build the plane according to the data later."
"Besides, Huangya Cave is so small, there is no room for such a large plane."
"Okay, then I'll obey your command!"
Huang Zhefu said happily.
"I heard that the students in the flight school have never touched a real plane yet?"
Zhao Tianyang instructed: "When you go back, you must make them study hard, otherwise who will fly the plane I built to fight the Japanese in the future!"
"Do not worry!"
Huang Zhefu patted the wings of the Taihang Type 1 transport plane and said, "With it, we will be able to train enough transport plane pilots in less than half a year!"
"Well, a transport pilot means you can only fly planes, right?"
Zhao Tianyang scratched his head: "Forget it, it's better to have it than not."
The next day, Huang Zhefu sat in the driver's seat of the Taihang Type 1 transport aircraft and complained.
"Hey, Chief Zhao, when can you install the aircraft cover? It makes my hair a mess every time I fly!"
"Don't worry, I'll arrange it for you next time you come!"
Zhao Tianyang agreed readily.
He wanted to equip the plane with not only a cover, but also machine guns, aerial bombs and other equipment.
"Then it's settled!"
After saying that, Huang Zhefu put on his cotton jacket, put on goggles, turned the key, started the plane, and drove towards the runway outside the cave.
After a moment, looking at the transport plane flying into the sky, Zhao Tianyang turned back to the tent and began to draw the blueprint.
A week later, Zhao Tianyang found Shen Hong with the drawings.
"Come, take a look at this, my newly designed anti-aircraft machine gun."
"Anti-aircraft gun?"
Shen Hong took the drawing with a puzzled look on his face and started looking at it.
"We are currently extremely short of anti-aircraft weapons, and it just so happens that armored vehicles and the Taihang Type 1 transport aircraft also need a powerful machine gun."
"So I designed this anti-aircraft machine gun. What do you think?"
Looking at Zhao Tianyang with an expectant look on his face, Shen Hong carefully calculated the data of this machine gun and gave him a thumbs up.
"I can only say that he is worthy of being our section chief. This technology is as stable as ever!"
"Haha, keep a low profile!"
Zhao Tianyang said modestly.
"This anti-aircraft machine gun has a simple structure and is light in weight. It should not be difficult to manufacture."
Shen Hong hesitated for a moment and asked, "It's just that this titanium alloy... we don't seem to have developed it yet, and we don't have this optical sight either!"
"I'll have the ironworks produce the titanium alloy. As for the optical sight, forget about it until the glass factory is built. For now, we'll just use the machine sight."
Zhao Tianyang replied immediately.
"Then I have no problem!"
Shen Hong put away the blueprint: "I will organize workers to manufacture this anti-aircraft machine gun!"
"Okay, then you go ahead and get busy!"
After leaving the arsenal, Zhao Tianyang went to find Liu Ding again and asked him to make aerial bombs and bullets for anti-aircraft machine guns.
"Don't worry, Chief. They are just enlarged grenades and rifle bullets!"
Liu Ding assured confidently: "I can develop it for you in a week at most!"
"Then I'll wait and see!"
After solving the problem of bullets, Zhao Tianyang went straight to the ironworks.
"Titanium alloy is an alloy formed by titanium, aluminum and vanadium. It has the advantages of high hardness, low density and fatigue resistance. The proportion is 95% titanium, 4% aluminum and 1% vanadium."
Li Tie took a notebook and kept recording the recipe Zhao Tianyang said.
"I'll ask Liu Ransheng to deliver the ore to you."
Zhao Tianyang solemnly instructed: "Remember, the formula of this titanium alloy must be kept strictly confidential."
"Except for you and the two factory managers Chang San, no one else is allowed to ask or inquire. The confidentiality level is top secret!"
"Top secret level one!"
Li Tie was very surprised when he saw the formula in his hand. He didn't expect that this titanium alloy was so important!
"Don't worry, Chief. After I memorize this formula, I will burn it and will never let anyone else know it!"
"Ah That's good!"
Zhao Tianyang nodded.
To be honest, he still values titanium alloy.
This thing only appeared in 1954 and was specially designed for aircraft engines. With it, Zhao Tianyang will have the capital to negotiate with the United States in the future.
...............
In the tent, Zhao Tianyang was fiddling with the experimental equipment in front of him. He was preparing to finish the aircraft cover.
Generally speaking, aircraft covers are either made of glass or plexiglass.
But their glass factory is still under construction, and after it is completed, the first things it will produce will be scarce military supplies such as telescopes and optical sights.
Therefore, Zhao Tianyang decided to manufacture plexiglass specifically for the production of aircraft covers.
First, Zhao Tianyang mixed "sodium cyanide" and "concentrated sulfuric acid" to react and produce "hydrogen cyanide".
After being purified by distillation, "hydrocyanic acid" reacts with "acetone" to produce "acetone cyanohydrin".
"Acetone cyanohydrin" reacts with "sulfuric acid" to produce "methacrylamide sulfate".
After hydrolysis, "methacrylamide sulfate" is esterified with "methanol" to obtain crude "methyl methacrylate".
Finally, "methyl methacrylate" is salted out and distilled to obtain the finished product.
Zhao Tianyang then heated the "methyl methacrylate" and poured it into the mold using the casting method.
Soon, a piece of plexiglass with high transparency, good mechanical properties and light weight appeared in front of Zhao Tianyang.
Oh, I forgot to mention that "methyl methacrylate" is also called "acrylic"!
