Chapter 126 Liu Xiu’s tips

In this regard, Liu Xiu could only lament the arrogance. Thinking back to the time when Liu Xiu led the second battalion to rob the Japs' transport team, they only managed to obtain nine barrels of oil, a total of less than two tons.

And now the ten tons of oil are available with just a telegram. Although it has not been delivered yet, the chassis of the banquet to the arsenal are all in the hands of the Eighth Route Army, so Liu Xiu is not worried that the transport team will not be able to get through. .

In the evening, I also rested in the open air with the soldiers of the New Third Regiment.

Although Liu Xiu did this to show off, after all, no matter how the dormitory of the arsenal was lacking, Liu Xiu could not be missing the position of regiment leader.

But sometimes this is the case. Living and eating with the soldiers can improve the cohesion of the soldiers and the morale of the soldiers!

After getting up, he first arranged for people to take the soldiers to cut wood and build dormitories, and then ran to Liu Qin's aircraft manufacturing factory and watched Liu Qin modifying and drawing on the drawings on the desk nearby.

So Liu Xiu leaned over and asked:

"Dad, are you modifying the aircraft drawings?"

Liu Qin replied without raising his head:

"Yes! Yesterday I strengthened the landing gear of the plane, but this increased the weight of the plane, which naturally reduced the plane's carrying capacity, so I was looking to see where the plane could be reduced!"

When Liu Xiu heard this, he thought for a moment and then said:

"I saw that the planes are all made of wood. Only the two engines are the heaviest. Each engine weighs as much as a person. It would be great if we could build an engine that can achieve the same horsepower with an average weight reduction and a simple structure. Got it!"

Regarding Liu Xiu's words, Liu Qin sighed:

After Liu Qin heard Liu Xiu's words, he said without thinking:

"Oh! Why didn't I think of that! You can use a two-stroke engine! This way you don't need a valve!"

When Liu Qin said this, he suddenly paused, then slapped his forehead and said:

"How can an engine be so easy to make? The crankshaft, pistons, valves and valve springs are all difficult things to make!"

Liu Xiu on the side also smiled after hearing Liu Qin's words. Sure enough, Liu Qin, a master in mechanics, knew about two-stroke engines.

"So when things look simple, they tend to be more difficult to make! Where can there be an engine that doesn't require valves and pistons..."

"Dad, I've also dismantled this kid's motorcycle engine. I think it's difficult to fix the valve piston and valve spring in this engine. It would be great if there was an engine that didn't require valve piston! Just like the one you made before. It looks pretty simple like an exploding engine!”

"Dad, what is this two-stroke engine? Doesn't it need a valve?"

However, Liu Xiu still pretended to be ignorant and asked:

After hearing what Liu Xiu said, Liu Qin drew a simple schematic diagram of a two-stroke engine in the blank space of the drawing with a few strokes, and then said to Liu Xiu:

"Look, this is the two-stroke engine I'm talking about! Its cylinder intake and exhaust are not controlled by the valve piston, but by the piston of the engine cylinder itself. This greatly reduces the complexity of the engine. That's great! With the current industrial capabilities of our arsenal, we can try to produce hair using sand molds!"

Liu Xiu saw that Liu Qin had already thought of a two-stroke engine and planned to try to manufacture it, so he nodded and said: "Dad, then let the people at the arsenal cooperate with you! I still have to command me The New Third Regiment is building your aircraft manufacturing plant!"

In response to Liu Xiu's words, Liu Qin waved his hand and let Liu Xiu do what he wanted, while he himself took a simple drawing of a two-stroke engine and began to meditate. Seeing this, Liu Xiu naturally didn't want to bother him here. Dad’s engine design.

After Liu Xiu returned to his New Third Regiment, he found that the thatched houses built by the New Third Regiment for part-time residences were also decent. Because they were not permanent housing, they did not use fired adobe bricks and tiles at all. used as materials for building houses.

Several wooden sticks about two meters high and as thick as arms were inserted into the ground, and then a few beams were put on them. Then the woven thatch mats were spread out one after another, and a thatched house that was as tall as one person was completed. Of course, the same is true for the walls around the thatched house. The mat made of thatch mixed with twigs becomes a wind-blocking wall.

Of course, such a simple thatched house can only be used for occasional living. If you want to live firmly for a long time, it can also be upgraded.

For example, operations such as applying yellow mud to the thatched mats used as walls to reinforce them.

So with the joint efforts of three thousand people, only the next night, all the soldiers were able to live in thatched houses. After all, although the weather is not cold now, it is unbearable to live in the wild all the time. !

········

Time flies at work. Three months have passed in the blink of an eye since Liu Xiu brought the soldiers of the New Third Regiment to the arsenal to work as construction workers.

In these three months, the New Third Regiment led by Liu Xiu accomplished two major events. The first major event was to build an airport runway with a length of one thousand meters and a width of fifteen meters.

That's right, Liu Xiu led a new regiment of more than 3,000 soldiers to not only double the width of the road in front of the arsenal, but also paved it with a layer of asphalt pavement to form an asphalt pavement runway.

As for the asphalt, it was naturally sent from Yanchang Oilfield, and Liu Xiu was not polite after getting a large amount of diesel. He immediately turned the tank into a bulldozer and a road roller. After all, he used the sand mold pouring method to build a The three-meter-long bulldozer bucket is still very simple.

Outside of this one-kilometer-long airport, there are several aircraft production plants.

The largest one is an aircraft assembly plant, and the remaining ones are aircraft parts processing plants.

Of course, these are trivial matters in terms of Liu Xiu's hard work in construction. The most important thing is that Liu Qin's two-stroke engine has finally been successfully mass-produced.

First, the engine casing, piston and crankshaft are directly poured using the desert pouring method. Then the machine tool is used to process and polish them so that they can almost fit. Of course, the life of the engine processed in this way will not be long.

Liu Qin himself has done experiments, but after running for more than a hundred hours, the moving parts in the engine were worn to the point where the engine could no longer run smoothly.

After replacing the original four-stroke engine of the three-wheeled motorcycle with a two-stroke engine, not only the horsepower increased, but the weight was also reduced.

Under Liu Xiu's suggestion, the wooden aircraft was also reinforced. For example, a steel beam was installed inside the wing to increase the strength of the wing and prevent it from appearing when doing difficult maneuvers. A broken wing situation.

Naturally, Liu Xiu was the first to become a test pilot for this Cricket aircraft equipped with a new engine.
