Release that Witch Chapter 544: New source of power

Do you yearn for the new world ... Roland becomes silent laughs.

He then brought Anna to Nightingale.

At this time, the former will always evade and give the two alone space.

Anna is wearing a light blue one-piece skirt today. Black stockings with knee-high knees can be seen under the skirt, coupled with a pair of buckskin boots, looks full of vitality. These modern clothes are made by Roland during the leisure time, and the fabric is a flowing coating provided by Soraya. They are lightweight and durable, and they are very suitable for her processing equipment.

When seeing her watery eyes, Roland will involuntarily smile.

Of course, he doesn't need to be as honest as before.

Put Anna on your leg and sit down, sniffing her hair from behind. Roland first got close to the topic, "I want to develop a new source of power." >

"Like steam engine?" She turned her head and walked down the white neck to see her prominent collarbone.

Roland couldn't help but reach out and touched, causing the latter to emit a low, shallow laugh.

"Your Majesty, it's business."

"cough cough, okay," he put down Anna, and pulled out a stack of design drawings from the manuscript at the table, "You look at this ... how much can you understand?"

"Yeah ......" Once in the learning state, Anna's expression will be completely immersed. Just looking at her selfless look, Roland will feel an inexplicable shame -- as if he is sitting in the window Mingji In Liang's classroom, the Xueba sneaking at the pen beside him was at the same table.

In order to balance this mentality, he decided to let Anna bow for mercy at night.

"Probably understand," Anna turned the last drawing and nodded after thinking about it for a while. "It is also driven by steam, except that the driving piston is replaced by a windmill blade, thus eliminating the connecting rod. Am I right? "

"Exactly," Roland put away the reveries in his head, put on a serious face and said, "Its name is steam turbine. It is still driven by high-pressure steam in essence, but the efficiency is higher than the reciprocating steam engine. More. "

This is the revolutionary product that Roland has long conceived.

It can be said that the basic industry is freed from the witch restriction. This is also the original intention of --, so that Anna can focus on higher-end machinery production.

steam turbine is his attempt in this field.

The use of steam turbines is extremely wide, both as marine power and thermal power, especially the latter -- can foresee that after Fallen Dragon Ridge is recovered, Speer Earl will have to stay in her town for a long time to handle government affairs, relying only on Mystery Moon One person's magic power is reluctant to maintain the night lighting of the factory area, not to mention the electrical engineering of the residential area. Of course, Roland is unwilling to admit that this is a planning failure caused by its lack of experience. To make up for this mistake, it can only use conventional means to generate electricity.

steam engine is inherently defective in the principle of circulation, resulting in high currents and low currents. Circuit voltage regulation is also a weak point of Roland. Therefore, steam turbine with more stable output power and higher thermal efficiency is a more suitable choice.

"What shall I do first?" Anna asked.

"Like the last gunship," Roland turned to a page with blades, "create a working verification model, not too big, about one meter then it will be alright, mainly to solve the problem of blade angle, can Let high-pressure steam pass through each of the stationary blade grills smoothly. As long as you do this step, you will be more than half successful.

Without detailed data, how to make a usable product like this?

It's just trial and error.

Regarding the core -- impeller part of the steam turbine, Roland has no worries about processing difficulties. The cutting accuracy of black fire is far better than that of machine tool in the future. He does not need to worry about the strength of the material. In the meantime, the alloy steel found out by Lucia is sufficient for this working strength. The key lies in the matching of the angles of the stationary blade cascade and the moving impeller. The former is like a fixed fence, adjusting the angle of steam passage, to avoid a swarm of bees hitting the impeller, resulting in chaotic direction or even opposite forces, which are essentially the same Comb for combing the airflow.

If the model can run normally, there will be no difficulty in scaling up.

When the processing methods and materials are improved, it is inevitable that a fruitful industry will bear fruit.

"I see," Anna's eyes flashed eagerly.

"Not in a hurry," Roland held her hand. "You should have heard Wendy, I decided to take the initiative to capture Devil."

"Yeah," Anna blinked, "Will you follow this time?"

Roland slowly shook his head.

"That's fine," she rested her head on his shoulder. "I saw you hurt last time and scared me to death."

"Really? But I heard Nightingale said that you are the most calm one on the spot. If it wasn't for your decisive treatment, I might really be --"

Having said that, his mouth was covered by the soft hands of Anna. "It is not allowed to say that word casually."

"I see." She let go of her palm when Roland nodded. "In short, I want to say that you must protect yourself, understand? In the event of an accident, use God Punishment Sigil immediately, do n’t hesitate, Even if you do n’t catch Devil ... I will wait for your triumph at the castle. "

"Relax," Anna laughed, "I won't let them hurt other witch."

...

After she left, Roland was silent for a long time whispered, "Are you there?"

"Of course," the figure of Nightingale appeared on the desk. "But I didn't overhear what you said. I came back when I saw her leave."

He stood up, walked to the window, and looked at the direction of the snow mountain. set off Before, you have to rehearse a few times in advance to familiarize yourself with the entire capture process and the tasks that you are responsible for. But this is only for a small number of pursuits Devil Set up the plan, how to do it depends on the actual situation situation Adjustment. "Speaking of him here paused , "If the capture operation encounters the worst kind situation ... I mean the irreversible one, you have to put it anyway Anna Bring it back. "

Nightingale didn't immediately answer, until Roland turned her head and looked at her, she said complexly, "Is this the real reason why you don't go?"

Roland did not deny, "Otherwise you would definitely choose to save me, right?"

"... I see," she sighed, "I will do my best."

"I can only believe you, apart from her," Roland patted her shoulder, word by word.
