The night wind is howling, and the lonely moon is hanging high!

Together with Xiao Su, he returned to the arsenal and everything was ready!

A small wooden boat shaped pottery fan was the first to be consigned here, it can be seen that this should be the chassis of the windmill, obviously, it is larger than the chassis of the previous windmill, 7m long, 2.5m wide at the widest point, and about 1m deep.

"Xiao Su, it seems that the Windranger 3.0 series is a lot bigger?" he estimated the size of the chassis in front of him and guessed.

Xiao Su smiled: "The 3.0 series is a seven-seater, and this is also the first time to try to make the windmill so big, it was smaller before, and it is also related to the lack of toughness of the steel structure!"

The boat-shaped pottery fan was in place, and the blood-red molten iron from the furnace was poured into it.

The four salamanders were given a short break, and all of them were small ones, with black skin scales, large eyes, osprey faces, and pointed beaks, side by side, except for the slightly taller leader, who was literally quadruplets. One by one, with their beaks as hard as iron, leaning against the side, panting, and even when they gasped, there were wisps of fire in their mouths.

There were a total of ten foundries, uniformly dressed, and all dressed in neat black metal scale armor, which was somewhat similar to the black skin scale armor of the salamander. With a metal veil on his head and dark crystal eyes, he is fully armed, and his function and number are printed on his back. Foundry is divided into: stoker, micro operator, grinder, and welder!

Two of the foundries, standing at the back of the furnace, manipulated the connecting levers and prepared to turn the furnace.

Xiao Su waved his hand: "Let's start!"

Su San stood in front of them, commanding them, concentrating, and began the first part of the grout casting.

I saw that the connecting rod pryed the outermost large gear at the bottom of the furnace, and the large gear drove the inner pinion, and the base of the furnace was welded with two chain tracks, and the pinion and the track were tightly occluded, and with the slow rotation of the pinion, the whole furnace began to tilt slowly.

The furnace itself weighs ten tons, and there are three tons of steel melt in it, so it is still a little difficult for two foundries, one person to operate a connecting rod.

The whole grouting process is neither fast nor slow, fast, easy to fail, causing danger, slow, the molten slurry will cool, the viscosity will increase, and the probability of one-time molding will be reduced. Therefore, it is particularly important to have a group of experienced foundry engineers for the manufacture of high-grade steel series equipment.

The vertical furnace slowly tilted sixty degrees, and suddenly, a red fluid with flames and a viscous blood flowed out from the mouth of the furnace's nozzle.

Squeak!

Peng!

The molten slurry flowed into the pottery fan, and the temperature inside instantly increased, and the sound of air explosion was endless.

The hot molten slurry, the high temperature close to 3000 degrees, the heat is manic, so that the surrounding air has to reach the limit of burning!

Soon, all the air in the pottery fan was discharged, there was no sound of air explosion, and the grouting was completed. Su San immediately waved his hand, the connecting rod was leveraged, the gear turned quickly, and the furnace was slowly straightened. The four salamanders quickly returned to work and began to breathe fire again.

This is the benefit of salamanders, which can provide enough flame in the fastest time to maintain the high temperature in the furnace and prevent the molten slurry from cooling and agglomerating.

The chassis of the windmill is one of the most critical parts of the whole structure, and the whole grouting process is very smooth.

"Mr. Su San, you have worked hard here, I have something to do with Brother Xiu, go to the design room, you can call me if you have something!" Xiao Su commanded.

"Okay, young master!" Su San nodded, organized the work in an orderly manner, and began to prepare for the casting of the next key component.

He followed Xiao Su and stayed away from the steaming and roasting of the furnace, and his heart was instantly refreshed.

Located at the southernmost end of the whole factory, the three-zhang square drawing room, brightly lit, the bookcase displays rolls and volumes of parchment drawings, some of the parchment drawings have been years, serious dehydration, the pages are yellowed, with black spots, a strong smell of rotten wood, some pungent.

In the middle of the room, there was a large rectangular table, on which was covered with a new scroll of drawings, soft and white, and at first glance it was known that it was a fine lambskin, and it was brand new.

"Brother Xiu, let's take a look, the blueprint of the Windranger 3.0 series!" Xiao Su smiled and bared his teeth, and slowly spread out the roll of parchment and presented it under the light.

The parchment scroll, which is one zhang long and two feet wide, and the lines outlined by Qianmo are clear and bright, and the first thing that catches his eye is the perspective view of the Windranger 3.0 series. Although the brushstrokes are still a little jerky, the whole design concept is fully revealed.

The predecessor of the 3.0 series has a sharp and smooth streamline, a light and agile tail, with a total of three wind wheels on the two wings and rear wing to provide forward momentum, and one wind wheel on top to provide upward power. The front face of the 3.0 is an integrated see-through glass design, and the portholes on both sides are more fluid and humanized.

He nodded, looked at Xiao Su with approving eyes, and said: "It's beautiful, the seven-seat extended version, the streamline is bright and smooth, the proportions are reasonable, the shape is beautiful, and the dynamics are very strong, but it looks a little familiar!"

When Xiao Su heard this, he suddenly smiled and said, "This is my new invention, how can you have seen it?"

After looking closely, he wondered that it was indeed a little familiar, but it was not like some birds of prey flying in the sky, and suddenly, the image of a sea creature appeared in his mind.

"Dolphin, isn't this a dolphin?" he suddenly realized and smiled happily.

The streamlined shape, the seven-seater is lengthened, the head is slightly larger, the tail is light, and the overall appearance is seventy percent similar to that of dolphins.

"Okay, even if you have a bad eye, my idea came from a dolphin, but the original idea was not a dolphin, it was a white-sided dolphin in a freshwater lake!"

"It's a dolphin, a flying dolphin, it's pretty good, you're using the knowledge of bionics!" He still admires Xiao Su's masterpiece very much, although it is a little simpler, but it is reasonable.

"There should be room for improvement!" Xiao Su smiled indifferently.

Then, his attention focused on the design of the wind wheel, according to the design drawings expressed, the operating principle of the wind wheel is actually not complicated, the appearance of the round turbine, the diameter of three feet, six turbine blades, the wind spirit stone is placed in the central axis position, through the wind spirit stone continues to spray thin wind elements, drive the turbine to rotate, form a driving force.

"Xiao Su, does the power of the Wind Turbine have anything to do with the energy efficiency of the Wind Spirit Stone?" he asked.

"Yes, an ordinary wind spirit stone can only drive a wind wheel of this specification, and the speed of the blades can reach 1,000 revolutions per second!" Xiao Su stood aside and replied.

The size and speed of the turbine blades determine the amount of forward or upward driving force, and ultimately depend on the energy efficiency of the wind spirit stone. Wind spirit stone is a relatively common wind element ore in nature, and the purity is generally between 50%-60%.

He held the parchment roll, looked at it carefully, pondered for a moment, and a bold idea came to mind: "Xiao Su, if Qingyuan stone is used to drive the blades of this turbine, what will be the result?"

This idea, Xiao Su also had, although the wind element stone and the wind spirit stone are both the crystallization of the wind element, but the essence is different, the wind energy in the wind element stone, compared with the same volume of the wind spirit stone, is thousands of times larger, the reason is that the microstructure of the wind element condensation is completely different, it is obvious that the microstructure of the blue yuan stone is a higher grade.

Xiao Su pondered for a long time and replied: "The speed of the blades can reach almost 10,000 times per second, but because the friction between the wind element and the turbine blades is too great, the heat generated cannot be discharged in time, and the high-speed wind wheel will soon collapse!"

"Isn't that a change of material to make a turbine blade that can maintain a certain stiffness in a high-temperature environment?" he thought.

"Theoretically feasible, it's not difficult to do this, it's just that Feng Yuan Stone is not easy to find!" Xiao Su shook his head.

"That's right!" he laughed.

If there are enough Qingyuan stones to provide unlimited kinetic energy and create a flying machine that can travel at kilometers per second, it will make a great difference in military warfare.

For a whole night, ten foundries completed the casting of all the components of Windranger 3.0, and they also took one to two days to complete the assembly work. Windranger 3.0 consists of 108 components, chassis, superstructure, flanks, rear wings, propeller shafts, turbine blades, connecting elements and floor brackets, all made of fine steel.
