Four days later, the caravan ships raised sails and sailed away from the dock.
Tassa and a hundred First Army soldiers set off for the royal capital with the ship.
These days, Roland and Margaret have reached an agreement that Tassa can withdraw any amount of Golden Dragon from her shop, and the fee will be deducted from the amount of the steam engine sold. In addition, Roland will also need to pay an additional one percent of the interest.
This time, the saltpeter and ore ingots brought by the other party were almost twice the last time. However, with the deposit for the transformation of two inland boats, Roland still received more than 2,200 golden dragons. This was almost an unimaginable number in the Month of the Demon Even if the ore sold for a month was only 300 golden dragons.
After the caravan left, Maisie also arrived at the time of leaving Border Town.
According to the agreement with Ashes, she will go to the fjord islands and bring news about the Western border.
Roland wrote a long letter to her. In addition to expressing her attitude of mutual assistance and cooperation, she also hoped that the Five Kings could send some auxiliary witches to assist her.
In the letter, he did not regard himself as his brother, but negotiated the matter as the lord of the border town and the priest of the western border.
Although the possibility of the other party agreeing to him is very small, he still wants to try it out, writing a few more words will not take much effort.
The farewell spot was in the castle backyard and all the witches arrived.
Nightingale gave her a small bag of dried fish slices; Lightning gave her a packet of pepper.
The other witches walked forward with reluctance to touch her feathers, and hugged her and said goodbye to her was like a farewell forever.
Don't worry!She raised her head and said, I will be back soon, Gu!
What if Tilly doesn't let you come back Ah, said Lightning worriedly.
Gu... The pigeon shrank his neck and thought for a while, shook his tail feathers, and then I flew back secretly!
Then we agreed, and the little girl made a serious promise, if you come back, I will catch a bunch of birds to roast for you.There is also the beehive we discovered last time, so let it be taken away when you come.
Gu!She nodded repeatedly and agreed!
What else can I say?Roland was filled with emotion. In just one month, he completely turned Maisie to his side.Beautiful job, lightning!
So, goodbye everyone!Maisie spread her wings, ran aid on the ground for a while before slowly flying up, and then gradually disappeared into the southeast after hovering for two laps.
She can arrive smoothly.Roland looked at the slow movement and couldn't help but feel sweat for her.
No problem, Lightning said without hesitation, then tilted his head, it should be... right?
After seeing off Maisie, Roland soon devoted himself to his busy daily work.
This time, he will draw a complete design for the two ships to be transformed by the Fir Moon Bay Caravan and they will also become the world's first steam-powered paddle steamers.
Due to the use of a single power source, the steam engine power shaft can be directly connected to the paddle wheel without the need for a gearbox.
Use multiple intake pipes to control the intake volume to control the ship speed.
When you want to slow down or stop the boat, just close the intake pipe so that the excess steam will leak out from the exhaust port.
At this time, the fire remains in a burning state, so it is convenient to speed up again.
The principle was not difficult, and Roland quickly drew a rough model.If you want to get accurate drawings, you have to go to the site to measure the specific size.
At this time, Anna walked into the office with a book in her arms.
What's wrong?He put down his quill and couldn't help but smile.
After reading this book, she placed the book on her desk, which was the book "Theoretical Foundation of Natural Science".
Roland's smile suddenly froze on his face. This is too exaggerated. Has he finished reading all the math and physics knowledge at high school level in just a few months?
He didn't ask the other party if he understood it, because after reading Anna's reading it means she fully understands it, otherwise she would definitely look it over and over again or ask herself.
Do you want to use steam engines to replace sails to power boats?Anna's attention was quickly attracted by the sketches on the table, but...
But what?
These two wheels are similar to paddling, right?Thrust can be generated when rotating, but half is exposed, which is equivalent to wasting part of the power.Why not bury it all in the water?
... Roland was stunned for a moment, not knowing what to say.
It is impossible for a person who is born to know, that is, she made the above judgment based on this momentary impression alone?
He suddenly became interested, what do you think should I do?
Anna thought for a while, picked up her pen and began to draw pictures on the paper.
Roland held her chin and admired with great interest that the bangs she had slipped from her hairpin when she was carefully plotting, swaying back and forth with her movements. Her slender eyelashes jumped from time to time, and her fair cheeks revealed a natural rosy.
Although only side faces can be seen at this angle, the outline from the bridge of the nose to the chin and then to the neck formed a perfect and soft curve against the backdrop of light.
Want to eat fish fillets?Nightingale approached and inserted her hand between them.
Well, Anna nodded, holding the snacks handed over by the latter, thank you.
Roland, whose vision was blocked, coughed twice and had to turn his gaze back to the paintings on the desktop.
At the beginning, Anna tried to place the paddle wheel horizontally and buried it completely in the water, but this would make it difficult to observe the position of the wheel when the ship was docking, which could easily cause it to hit the dock or pier.
Then she arranged the paddle wheel to the stern, which was also a common practice, but the transmission setting was much more complicated. After all, the bulky steam engine was not suitable for being placed at the end of the hull, so that the transmission shaft and gearbox would occupy a considerable part of the hull.
When Roland saw the new drawings she drew, he couldn't help but be amazed at the other party's keen thinking ability again.
The sketch Anna was thinking about was infinitely close to the arrangement of a single-axis propeller. The steam engine was set at the bottom of the hull, and the transmission shaft extended from below the waterline. The end was connected to four square blades, which looked a bit like a windmill.
I don't know if this can be done, she hesitated. Logically, as long as the paddle is kept at an inclination, the horizontal force can be generated, but I reduced a paddle wheel, and four paddles alone may not be able to push the hull.
Of course, just a little modification.Roland took the quill from Anna's hand and drew the original appearance of the propeller. Compared to the windmill shape, this shape of blades is more suitable for rotating in water.Your idea is completely correct, but the contract requirement is to transform it into a paddle steamer, so we should follow the first method. This has nothing to do with technology, but a business strategy.He paused, I'm going to test the hull data now, are you going to come with me?
Anna blinked those blue eyes, yes!
After mastering the theory and verifying it in practice is the best learning method.
……
nightingale?
When Anna followed the prince to the door, she saw Nightingale still looking at the drawings on the table and couldn't help but speak.
Ah, you guys go first, I'll come soon.
After comparing the sketches in her hand repeatedly, she concluded: Didn’t it just change the place where the wheels were placed?
