Bright Sword: Starting from the Improved Grenade

The next morning, Li Yuncai hung a simple map on the tent and preached to the people in front of him.

"Please look, after entering Cigulang from the bottom of the mountain, you will reach a small basin in the mountains after climbing a gentle slope. After the small basin, there are various cliffs and caves with flowing water."

"We also found a natural cave in the air above the east cliff. I climbed up and saw that it was about 25 meters high, 18 meters wide and 72 meters deep. The cave was dry and the temperature was suitable for storing supplies and ammunition."

"The mountains to the northeast are gentler, with some wild peach trees and cypress trees. Generally speaking, it is very troublesome to build an arsenal. Workers have to transport materials up between cliffs and risk falling off the cliffs while working."

"As I said, if there are difficulties, we must overcome them."

After Li Yuncai finished speaking, Zhao Tianyang stood up and encouraged everyone: "We are only taking a risk now, but our soldiers are still fighting the devils with bare hands. What is this little difficulty of ours?"

"The factory manager is right. At worst, I can just work while tied up with a rope!"

"That's right, when people are united, even Mount Tai can be moved."

Everyone agreed.

"Comrade Zhao Tianyang, we are here!"

At this time, a large group of villagers carrying various tools came from the foot of the mountain.

"It seems that the support promised by the deputy director of the Political Department yesterday has arrived."

Zhao Tianyang looked at Li Yuncai and said, "I'll have to trouble Comrade Li Yuncai to lead them in repairing the factory again this time."

"give it to me."

Li Yuncai patted his chest and said, "I thought about it yesterday. There are a lot of rock resources here. We can use local materials to build walls with stones and cover the roof with stone slabs. This way, the construction of the factory will be much faster!"

"it is good."

Zhao Tianyang looked at Liu Lao and the others again: "Comrade Li Yuncai is leading people to build a factory. We can't just sit there and build a bigger shed in the small basin, start running the machines, and produce some weapons."

"Reporting to the factory director, we don't have the resources!"

At this time, Liu Zaisheng raised his hand and said, "When we were in the 386th Brigade, we handed over steel, sulfuric acid, nitric acid, propellant, explosives, etc. to our brother troops."

"We only have machines now, we can't start work without supplies!"

"I go."

Zhao Tianyang patted his head speechlessly, wondering how could he have forgotten about this.

“How many oceans do we have left?”

"One thousand five hundred dollars."

Liu Zaisheng flipped through the notebook in his hand and replied.

"Forget it. Take a thousand dollars first. Go to the deputy director of the Political Department and ask them to help us buy some steel, sulfuric acid ore, coal, and whatever the arsenal needs."

At present, the Japanese forces in the southeastern part of Shanxi are not strong, and many counties and towns are in the hands of the Eighth Route Army and the Shanxi-Suiyuan Army. It is quite easy to buy some supplies needed by the arsenal with one thousand oceans.

"Row."

Liu Zaisheng nodded and wrote a note to withdraw one thousand dollars. Zhao Tianyang signed it, and then he could go to the material storage area to get it himself.

After Liu Zaisheng left, Zhao Tianyang scratched his head in pain. Ever since the establishment of the arsenal, he has been troubled by the issue of supplies. It seems that the issue of the airship is urgent.

"Mr. Liu, let's hold a meeting now to discuss the airship. Otherwise, even if we have the technology but no materials, we won't be able to build the weapons!"

"Okay, I'll bring the blackboard over."

Old Liu nodded. He had always had a complicated attitude towards airships. He always felt that this thing was unreliable, but there was no better solution at the moment, so he could only give it a try.

................

"Please see, an airship can be divided into eight parts: the hull, which is made up of multiple aluminum alloy frames and fiber skins; and the airbag, which is made of rubber and is used to store helium or hydrogen to provide buoyancy."

"Three propulsion systems, consisting of engines and propellers, are used to provide power for the airship to move forward, and four control systems, including control surfaces such as rudders, elevators and ailerons, enable the airship to turn, rise and descend."

"Five load bays, as the name implies, are places to put passengers, cargo, or equipment, and six landing gears, which are used to support the airship when it takes off and lands on the ground."

"Seven fuel systems, storing gasoline or diesel needed by the airship, eight electronic equipment, including communication systems, navigation systems, etc."

"It's a bit complicated!"

Yu Xiaping felt a headache as he looked at the densely packed words on the blackboard.

"This is complicated. What if we build airplanes in the future? Airplanes have to solve many more problems than airships."

Shen Hong on the side continued.

"Okay, this is the situation. Does anyone have anything to say?"

Zhao Tianyang put down the chalk and asked with a smile.

"Director, we know the structure of the airship, but we don't know how big the airship should be."

Wu Yunduo raised his hand and asked.

"Let me think about it!"

Zhao Tianyang stroked his chin and thought for a while, then picked up a piece of chalk and drew a picture of an airship, then marked the data of 248.6 meters in length, maximum diameter of 41.4 meters, weight of about 110 tons, and predicted load capacity of 363 tons.

After finishing writing, Zhao Tianyang looked at everyone and pointed at the data on the blackboard: "We will build the airship according to this data."

"Oh my god, 363 tons. If this works, we can find mineral deposits in Xinjiang, and then we will never be short of supplies again."

Mr. Liu sighed.

"To drive such a heavy airship, at least four 1100-horsepower engines are needed. Where can we find such powerful engines?"

Shen Hong calculated the airship data and asked.

"this......"

Zhao Tianyang scratched his head, feeling a little headache. He was only thinking that the heavier the load, the better, and forgot about the engine.

"I think we should cut the data of the airship in half, so that it can have a load capacity of more than 100 tons. Then we can use the engines of the Japanese Type 97 light bomber, and two of them will be enough to drive the airship."

Mr. Liu suggested after thinking for a moment.

"No, the Japs' engines are hard to get. I think we should try to build an engine ourselves. This way we can use it for airships, airplanes, and tanks!"

Cheng Mingsheng retorted.

"That's right. It's better to have it yourself than to have it yourself. I agree to build the engine. With the engine, we will have a lot of choices whether we build an airship or an airplane!"

Yu Xiaping echoed.

"hiss......"

Zhao Tianyang put down the chalk in annoyance, took out a cigarette, lit it and took a puff.

"How about this, everyone go back and think about how big the airship should be, and you can also try to draw a blueprint of the engine."

"Let's have another meeting at the same time tomorrow to discuss this."

"Okay, I think that's fine."

"We really need to think about this!"

Seeing that everyone agreed, Zhao Tianyang waved his hand and signaled the meeting to adjourn.
