Bright Sword: Starting from the Improved Grenade

"I go...."

Everyone was stunned as they watched the delta wing covered in dust, and for a moment they didn't know what to do.

"Hurry and save people!"

The deputy chief of staff showed fear on his face and was the first to react. He ran towards the delta-wing glider. Seeing this, others also reacted and followed him.

The deputy chief of staff ran over to the driver's seat and breathed a sigh of relief when he saw Zhao Tianyang trying to take off his seat belt.

"I'm glad you're okay! I was scared to death just now!"

"Don't worry, you won't die!"

Zhao Tianyang stopped, rubbed his butt, and complained: "I didn't have much power when I hit it. I'm fine, but my butt hurts a little."

Looking at Zhao Tianyang who kept complaining and speaking with full energy, the deputy chief of staff completely relaxed. He went up to help Zhao Tianyang take off his seat belt while joking.

"You are really lucky. You made such a loud noise but nothing happened!"

"That is, who am I, a person favored by God!"

Zhao Tianyang looked very proud. He was the protagonist in the legend. If he died, what would the readers still want to read?

"Okay, stop being so joking, come down quickly and find a doctor to check you out!"

The deputy chief of staff patted Zhao Tianyang on the head and urged.

"understood!"

"Chief, are you okay?"

At this time, other people also ran over one after another. When they saw Zhao Tianyang jumping off the delta-wing glider, they came forward and expressed their concern.

Zhao Tianyang patted his chest and said, "Don't worry, everything is fine!!"

"Great."

"As long as it's okay, it'll be okay!"

Liu Ding was very lucky that nothing serious had happened, otherwise he would have regretted it for the rest of his life.

"Okay, stop hanging around."

The deputy chief of staff asked everyone to disperse and do what they should do since they had watched the fun. At the same time, he stopped Zhao Tianyang who wanted to escape and insisted on taking him to see a doctor. Zhao Tianyang had no choice but to instruct Yu Xiaping to take the wreckage of the delta-wing glider back to the engine factory to check for any damage.

After being examined by a doctor for an hour in the evening and confirmed to have no serious injuries, Zhao Tianyang was released back to Huangya Cave by the deputy chief of staff.

As soon as he came back, he went to the cafeteria to eat some leftovers, and then called Yu Xiaping to the engine factory to prepare for a meeting.

"Chief, I have something to report!"

As a result, before he could even reach the engine factory, he was stopped by Liu Fugui.

"What's the matter? Tell me about it."

Zhao Tianyang asked curiously.

Liu Fugui: "Mr. Liu said that when we held literacy classes these days, fewer and fewer workers came!"

"?"

Zhao Tianyang was stunned at first, but then he reacted: "Go and investigate whether those workers who didn't come are usually very face-conscious!"

"Good face?"

Liu Guifu was a little confused. What does this face have to do with attending class or not?

"Go if I tell you to."

Zhao Tianyang smiled and said, "When you come back from your investigation, I'll tell you the reason!"

"All right!"

Liu Guifu nodded, turned and walked towards the classroom. He planned to ask the workers directly.

"Haha, men's competitive spirit!"

Zhao Tianyang shook his head and walked towards the engine factory.

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

"Chief, you're here!"

Yu Xiaping opened the door and welcomed Zhao Tianyang in.

Walking into the factory, Zhao Tianyang could see that the delta-wing glider had been hung up and disassembled into pieces. There was also a blackboard next to it with various data of the delta-wing glider written on it.

Six workers from the engine factory were sorting and repairing various broken parts.

"Well, do you see what's wrong?"

Zhao Tianyang asked.

"Have!"

Yu Xiaping happily said: "The reason why the wheels of the glider broke during landing is because there is no shock absorption system. When it came into contact with the ground, the weight of the entire glider and the force generated during landing were all pressed on the wheels. Because they were made of iron and wood, and there was no rubber to cushion them, the wheels broke into two pieces."

After that, he added with a regretful tone: "As for why the glider deviated from the course, I haven't checked it yet."

“No need to check this!”

Zhao Tianyang touched his head embarrassedly: "It should be my operating problem."

He had just thought that the reason why the glider deviated from the course was probably related to an air current it encountered during landing. He panicked and did not pull the control stick in time, causing the course to deviate.

"Oh, that's how it is!"

Yu Xiaping nodded and didn't ask any further questions.

"Okay, let's talk about the improvement suggestions for the glider first!"

Zhao Tianyang quickly walked to the blackboard and added a few strokes to the data chart of the delta-wing glider.

"First, we need to add a few springs to the glider to absorb shocks, so that the force applied during landing can be distributed to the entire fuselage instead of letting the wheels bear it alone."

After that, Zhao Tianyang asked Yu Xiaping, "How much fuel is left in the tank? How long did it take from takeoff to my return?"

"There were still 45 litres of petrol in the tank. It took about an hour, 60 minutes, from take-off to return."

Yu Xiaping answered without hesitation.

"There are a little over 54 liters of fuel in the tank, so the delta wing will consume about 9 liters of fuel for one hour of flight, and the altitude is about to meters."

While Zhao Tianyang was calculating, he wrote the new data on the blackboard.

Without a specific reference, he couldn't know exactly how far the glider could fly in one hour. However, based on the wind speed generated by the glider during flight, he could roughly infer that it should be around thirty to fifty kilometers.

Different wind speeds will have different effects on the human body, and a wind speed of level 5 will produce more obvious resistance to the human body.

A wind speed of level 6 will make it difficult for people to walk and the branches will shake noticeably.

A force 7 wind can affect body balance and even breathing.

"That's enough!"

Zhao Tianyang put down the chalk he used for calculations and said, "There are 54 liters of fuel in the tank. Even if we can only fly kilometers per hour, we can still fly kilometers. This cruising distance is more than enough!"

"So the section chief means that it should be finalized immediately?"

Yu Xiaping asked in confusion.

"Fixed!"

Zhao Tianyang nodded and said, "After adding the spring, we can start mass production."

Then he added: "But you still need to add the training steps before takeoff, otherwise you will end up like me, almost losing your life in a car accident."

“We really need to add a training step!”

Yu Xiaping agreed with lingering fear.

He doesn't want to see the plane crash this afternoon again.

"Chief, I'm back!"

At this time, Liu Guifu walked in with a surprised look on his face: "Chief, you are right. Those who gradually stop coming are usually those who are more concerned about their reputation."

"That's right!"

Zhao Tianyang explained to the two, "When it comes to basic learning, children generally learn faster than adults. People who care about their reputation naturally don't want to be outdone by children, so they simply don't go to school."

"I see."

The two suddenly realized that they didn't expect this to be the reason.

After confirming his idea, Zhao Tianyang said to Liu Guifu: "In this case, let's divide it into two classrooms, with adults and children studying separately."

"Teacher, go ask Wu Yunduo if he wants to be a volunteer."

"Okay, I'll go and ask."
