Yearning for a new world... Roland laughed dumbly.
Then he asked Nightingale to recruit Anna.
At this time, the former will always automatically avoid it, giving the two space to be alone.
Anna was wearing a short light blue one-piece dress today, with knee-high black stockings under the skirt, and a pair of moccasin boots, which made her look full of vitality. These modern-style clothes were made by Roland instructed the tailors in her spare time, and the fabrics were the running water coating provided by Soraya. They were light to wear and very durable, making them very suitable for her to use when processing utensils.
Roland couldn't help but smile when he saw her watery eyes.
Of course, now he doesn't need to be as honest as he used to be.
Pulling Anna onto his lap and sitting down, sniffing her hair from behind, Roland first got intimate before entering the topic, "I want to develop a new source of power."
"Like a steam engine?" She turned her head, and along her white neck, she could see her protruding collarbone.
Roland couldn't help but reached out and touched it, causing the latter to let out a low chuckle.
"Your Majesty, let's get down to business."
"Cough, okay," he put down Anna and took out a stack of design drawings from the manuscript on the table, "Look at this first... How much can you understand?"
"Well..." As soon as she entered the learning state, Anna's expression would be completely immersed, and Roland would feel an inexplicable shame just by looking at her obliviously - as if he was sitting in a classroom with bright windows. , peeking at the deskmate of the scholar who is writing and writing fast beside him.
In order to balance this mentality, he decided to make Anna bow his head and beg for mercy at night.
"I understand," Anna flipped through the last drawing, and nodded after thinking for a moment, "it is also driven by steam, but the pushing piston is replaced by a windmill blade, thus eliminating the reciprocating motion of the connecting rod. , am I right?"
"Exactly," Roland put away the reverie in his head and replied with a serious face, "Its name is a steam turbine, and in essence it still uses high-pressure steam to propel it, but its efficiency is much higher than that of a reciprocating steam engine. "
This is exactly the revolutionary product that Roland has been thinking about for a long time.
It can be said that it is also the original intention to free the basic industry from the restrictions of witches - only in this way can Anna concentrate on higher-end mechanical production.
The steam turbine was his attempt in this field.
The steam turbine is extremely versatile, it can be used as both marine power and thermal power generation, especially the latter - it is foreseeable that after the recovery of the Dragon Falls, Earl Spell will have to stay in her town for a long time. For government affairs, it is very difficult to rely on Miyue's magic power alone to maintain the night lighting in the factory area, not to mention the electrification project in the residential area. Of course, Roland was reluctant to admit that this was a planning failure caused by his own inexperience. To make up for this mistake, he could only use conventional means to generate electricity.
Due to the inherent defects in the cycle principle of the steam engine, the current sent out is sometimes high and sometimes low, and the voltage regulation of the circuit is Roland's weak knowledge. Therefore, it is a more appropriate choice to use a steam turbine with a more stable output power and higher thermal efficiency.
"What shall I do first?" Anna asked.
"Like the last gunboat," Roland turned to the page with the blades on it, "build a working verification model, it doesn't need to be too big, about one meter is enough, the main problem is to solve the angle of the blades, so that the high-pressure steam can be Go through each stationary vane grille smoothly. As long as you do this step, you will be successful for the most part."
Without detailed data, to create a usable finished product like this
Just trial and error.
Regarding the impeller part, the core of the steam turbine, Roland is not worried about the processing difficulties. The alloy steel that West Asia has explored is sufficient for this work strength. The key lies in the angle matching of the static blade cascade and the moving impeller. The former is like a fixed fence, adjusting the angle of steam passing through, so as to avoid swarming against the impeller, resulting in confusion or even opposite forces, which are essentially the same. Put a comb to comb through the turbulent airflow.
If the model works properly, there is no difficulty in scaling it up.
When the level of processing methods and materials is improved, it is inevitable to bear fruitful industrial results.
"I see," Anna's eyes flashed eagerly.
"Don't worry," Roland held her hand. "You should have heard Wendy say it. I decided to take the initiative to capture the devil."
"Well," Anna blinked, "will you follow me this time?"
Roland shook his head slowly.
"That's fine," she rested her head on his shoulder, "the last time I saw you injured, it scared me to death."
"Really? But I heard Nightingale say that you are the calmest one at the scene. If you hadn't dealt with it decisively, I might have really—"
Halfway through speaking, his mouth was covered by Anna's soft hand, "Don't say that word casually."
"I see," she let go of her palm after Roland nodded. "In short, what I want to say is, you must protect yourself, understand? If there is an accident, immediately use the God's Punishment Seal. Don't hesitate. Even if the devil is not caught... I will wait for your triumph at the castle."
"Don't worry," Anna laughed, "I won't let them hurt other witches."
…
After she left, Roland was silent for a long time before he said solemnly, "Are you there?"
"Of course," Nightingale's figure appeared on the desk, "but I didn't eavesdrop on what you said, I only came back after seeing her leave."
He stood up and walked to the window, looking in the direction of the snow-capped mountains, and roughly recounted the hunting plan he had envisaged in his mind, "Before you set off, you have to rehearse a few times in advance to familiarize yourself with the entire capture procedure and the responsibility for each other. Mission. But this is only a plan for a small number of chasing devils, and how to do it has to be adjusted according to the actual situation." He paused when he said that, "If the arrest operation encounters the worst situation ...I mean the irretrievable kind, you have to bring Anna back no matter what."
Nightingale didn't answer immediately, and when Roland turned to look at her, she said with a complicated expression, "Is this the real reason why you didn't go?"
Roland didn't deny it, "Otherwise you would definitely choose to save me, right?"
"…Understood," she sighed softly, "I'll do my best."
"Besides her, I'm the only one who can trust me," Roland patted her shoulder and said word by word.
