Bright Sword: Starting from the Improved Grenade

the next day.

Zhao Tianyang handed the chicks raised by the security team and the 120 chicks that had just been hatched the day before to Wang Weimin, asking him to raise them first.

"Don't worry, Chief Zhao. I'm the best at raising chickens!"

After getting Wang Weimin's guarantee, Zhao Tianyang came to the engine factory.

Just now Yu Xiaping sent someone to tell him that the single-cylinder engine was ready.

"How is it, have you tested it?"

Inside the engine factory, Zhao Tianyang asked with a little excitement.

"not yet!"

Yu Xiaping shook his head: "I've been waiting for you!"

"wait for me?"

Zhao Tianyang waved his hand and said, "Then quickly start the engine and start the test!"

"Yes!"

Yu Xiaping saluted and waved to several workers standing beside him.

Soon, a worker skillfully added lubricating oil to the single-cylinder engine.

Another worker filled the fuel tank next to the engine with oil.

"ignition."

Yu Xiaping personally came to the engine and turned the handle.

Driven by the power, the generator starts to generate electricity, and the spark plug stimulated by the electric current pops out sparks, igniting the gasoline entering the engine.

"Boom boom boom..."

In an instant, bursts of engine roars were heard.

"Great, it worked!"

Yu Xiaping showed his excitement. This was an engine he designed independently, so how could he not be happy!

"Oh, it worked!"

Although the other workers were not as happy as he was, being able to successfully build an engine was also something worth bragging about.

They hugged each other and jumped up and down excitedly.

"hehe...."

Zhao Tianyang smiled slightly: "It's not over yet! Hurry up and test the horsepower!"

"Yes, we also need to test the horsepower!"

Yu Xiaping nodded, and quickly led people to move in the large piece of iron that was used to test the horsepower of the pot-carrying machine.

Finally, after testing, this single-cylinder gasoline engine can generate a powerful power of 15 horsepower.

The reason why it is powerful is that gasoline engines are different from steam locomotives.

The powerful torque generated by the gasoline engine allows the engine to pull at least one to two tons of cargo.

After the engine was successfully manufactured, Zhao Tianyang took the various steel pipes made by Li Tie.

The propellers made by Li Yuncai were taken to the engine factory, and Yu Xiaping led the workers to assemble them.

"Is this...assembling an airplane?"

Looking at the steel pipes all over the ground, Cheng Mingsheng was a little hesitant. No matter how he looked at it, these things couldn't be connected with airplanes!

"To be more precise, it should be a delta-wing glider, similar to the assault gliders used by Germany."

"However, this one does not need to be towed by an aircraft and can take off under its own power."

Zhao Tianyang, who was standing by, was holding a brush and applying a waterproof coating to the linen while explaining.

"real or fake?"

In Yu Xiaping's impression, any aircraft that flies under its own power is not assembled with steel pipes, and has so few parts.

"Just try it and you'll know!"

Zhao Tianyang shrugged and continued to apply the waterproof coating.

"Fine!"

Out of trust in Zhao Tianyang, Yu Xiaping decided to give it a try even though it seemed unreliable.

Soon, referring to the drawings given by Zhao Tianyang, Yu Xiaping led his men to assemble the steel pipes on the ground.

At the same time, the newly manufactured engine was also installed.

It was not until this time, looking at the full view of the delta-wing glider in front of him, that Yu Xiaping nodded thoughtfully.

According to fluid mechanics, this thing seems to be able to glide on its own.

If you add a propeller and an engine, it would be a small plane, but it just can't carry much stuff.

The more Yu Xiaping looked, the more excited he became, and the more he admired him. What's wrong with this section chief's head?

To be able to come up with such a flying machine!

"Stop looking at it, come here quickly and help me carry this thing to the blast furnace and bake it."

At this moment, Zhao Tianyang, who had already finished applying the waterproof coating and the wear-resistant coating, shouted to Yu Xiaping and others.

(The wear-resistant coating is made of resin, aluminum oxide, and silicon carbide mixed and fired at high temperature)

"I'm coming!"

Yu Xiaping agreed and, together with several workers, lifted up the huge wooden frame that held up the canvas.

"Section Chief, this thing can really fly!"

As he walked towards the blast furnace, Yu Xiaping asked, unable to hide his curiosity.

"Nonsense, why would I build it if it can't fly!"

Zhao Tianyang showed a proud expression after saying this: "With this little thing, it will be more convenient for us to connect with the arsenals of various military regions in the future."

"But this delta-wing glider shouldn't be able to fly very fast! What if we encounter a Japanese plane?"

At this time, a worker who was carrying a wooden frame asked.

"What to do? Wait for death!"

Zhao Tianyang spread his hands and said helplessly: "Although this thing can take off and carry people."

"But the speed and defense are simply not comparable to those of airplanes, so if we encounter a Japanese airplane, we can only hope for the best!"

"It's okay. At most, we can just plan carefully every time we fly and avoid the patrol routes of the enemy planes!"

Yu Xiaping was very open-minded. He believed that having a manned aircraft was a huge breakthrough for the Eighth Route Army.

No matter what difficulties arise later, we can just overcome them slowly!

"You are quite open-minded!"

Zhao Tianyang smiled faintly.

In fact, he has a better way, which is to fly at night.

The speed of delta-wing gliders is not fast, but they are also very safe. As long as they rely on radio navigation guidance, they can fly at night.

"When you get to the mountain, there will always be a way!"

Yu Xiaping said casually.

In the evening, after dinner, Zhao Tianyang, Yu Xiaping and others hung the dried skin on the delta-wing glider.

"Now it looks a bit like a flying machine!"

Yu Xiaping looked at the still simple delta-wing glider in front of him, touched his chin and smiled.

"Okay, everyone go and rest, and come back for the test tomorrow!"

Zhao Tianyang on the side clapped his hands and asked everyone to go off work.

"Let's go."

"finished get off work!"

"Why get off work? I still have to go to class later!"

After a few joyful shouts, the engine factory door was closed tightly.
