Graycastle, Neverwinter.
Since the news of the enthronement ceremony was released, Roland handed over all the preparations to Barov, and the latter also seemed to be very attentive. Ms. Lan Qi invited Neverwinter, obviously not wanting to make any mistakes.
As for himself, apart from occasionally checking on the progress of the filming of the ghost, the rest of the time was devoted to the finalization of the internal combustion engine.
Due to a certain error in the weights and measures of the two worlds, the prototypes need to pass the stability test. In addition, the fractionated oil products are uneven, and design redundancy must also be considered. In the absence of realistic calculation methods , he can only use physical objects to debug.
Manufacturing experiments, scrapping, improving and repeating, Roland seems to have returned to the campus era, running between the castle and the mountains behind the north slope every day, living a busy and fulfilling research life, those knowledge that have not been touched for a long time, in this half month became clear again.
Of course, there was no Anna at the time.
Even better, she's just as passionate about new things as she is.
Whenever she sees the expression on her face when she focuses on assembling those precise parts, and when she touches the sweat on the tip of her nose and leaves a string of mimeographs, Roland can't help but feel that her desire for creation and knowledge seems to be innate. Like her flame, hot and pure.
This inner spirit is beyond the description of appearance, and can never get tired of seeing it at any time.
Whenever a decisive progress is made, Anna's smile can almost be described as blooming. He even feels that the joy of creation is far more for her than being a queen.
She has never concealed her thoughts, as long as the two can stay together, she doesn't care too much about the false name.
Of course, Roland also knows that sometimes the name is not to show to the other party, but to show everyone.
This cannot be avoided as long as humans remain social animals.
After marking a series of revised dimensions on the drawing, he put down the quill and rubbed his numb neck.
If nothing else, the design drawings in front of them are likely to be finalized. After all, the last batch of prototypes has been running stably for several days, and the accumulated working time can meet the current needs of use.
As a second-generation power source, the principle of the internal combustion engine is not complicated, and it can be regarded as an evolutionary version of the steam engine. The first-generation power source uses steam to push the piston. No matter how clever the design is, the energy loss caused by steam transportation cannot be avoided. Therefore, people naturally think that putting this force directly into the cylinder will definitely greatly improve work efficiency. , the internal combustion engine was born.
Oil is mixed with air and injected into the cylinder, causing it to burn violently. The expanded airflow will propel the piston to run, and at the same time suck new fuel into the cylinder. Sounds simple, but it is a huge project to achieve. For example, steam engines have relatively low requirements for sealing. In the early products, the gap between the piston and the cylinder block can even be stuffed with a finger. Felt and linen can be used to caulk the gap, but it is obviously not feasible to replace it with an internal combustion engine.
It is not powered by the outside like a steam engine. Every cycle of the piston needs to be completed by itself, so if the seal is not tight, it will cause the cylinder to stop due to misfire.
In other words, this simple principle can only be turned into reality when the level of materials and processing technology reaches a certain level. It is precisely because of this that the birth of the first internal combustion engine in history is actually decades later than the electric motor.
The first-generation internal combustion engine solution designed by Roland has two directions, one is the cylinder in-line type, and the other is the cylinder in-line type. The former is stupid, black and rough, made of cast iron, how to be stable, and strive to be put into the factory for large-scale production. The latter is also known as a radial engine. Due to its short crankshaft and compact structure, it can be made very small, which is very suitable for spacecraft use. On the whole, it is much more refined than the former, and the material is aluminum alloy, which can only be processed by Anna for the time being.
The reason why Roland dared to develop two sets of products in the research and development stage is nothing more than standing on the shoulders of his predecessors. For these two time-tested works, a lot of information can be found in the dream world. Compared with the steam engine that has been replaced four times, the starting point this time is much higher.
In addition to the information revealed by the high-level devil, he had to speed up his pace.
Relying on ground defense alone, it is difficult to be watertight in the face of a large number of threats from the sky, and this expedition has proved this.
If the plan can be realized, mankind will have the qualification to compete with the enemy in the air for the first time.
"Your Majesty, don't move."
Nightingale suddenly spoke.
Roland paused immediately and glanced back at the same time.
Are there... enemies
Then he saw Nightingale come over, reach out and caress the top of his head, then with a slight pain, she put a strand of hair in front of him.
"Uh, is this white hair?" Roland was dumbfounded for a while.
Although the gray hair color itself is very light, these strands of hair are indeed a little obvious, and they have almost lost their luster from the roots.
"And," Nightingale groped for a while, "Have you been resting too little recently?"
"Have it?"
"You used to sleep late in the winter, but recently you wake up earlier than me, and you have to enter the dream world at night, so you can't really fall asleep, right?" she continued, "Yawning from time to time is a proof of fatigue, you still Before the age of 30, white hair appeared, so how can I go on like this."
Seeing the other party's serious admonition, Roland couldn't help but feel a lot lighter, and even the fatigue from work faded a little. She really wasn't affected too much. It seemed that the agreement really played a crucial role.
"Don't worry, this is far from the limit. I have experienced this for a long time."
"..." Nightingale looked suspicious, but she could clearly tell that this was not a lie.
Because he really didn't lie, "In general, there will be a long period of heart palpitations first, as if the chest is very empty; then I feel that my whole body can't lift up, so be careful at this time. If the reaction is strong If you do, you will cough non-stop, and even cough up blood.”
Halfway through, he suddenly coughed violently.
"Hey, are you alright?" Nightingale suddenly showed a nervous look and patted him on the back, "Do you need me to call Nana?"
Roland took a deep breath, "No... It's okay, I just choked on my saliva just now."
"real?"
"Don't worry, I"
He turned his head, and couldn't help froze for a while, the distance between each other was almost close to each other, and under the eyes of the four, the two couldn't help but hold their breath.
"Your Majesty," at this moment, the door of the office was pushed open, and Wendy walked in, "I have something to do... eh? What are you doing?"
"Me?" Roland blinked, only to find that there was no one else in front of him, and he was half-reclined, even if he didn't need to say it, he knew that it must be quite weird.
"Your Majesty is practicing gymnastics," Nightingale was lying on the side of the coffee table for some time, chewing dried fish in a relaxed manner, "sitting for a long time will make his body sore, so he can try the effect first by himself. ."
"I see," Wendy said thoughtfully, "Is this the gymnastics technique you mentioned earlier that you plan to promote in the academy? But... does it really work like this?"
"Uh, it's alright," Roland resumed his posture awkwardly. For some reason, he always felt that the innocent-looking Nightingale was trying his best to hold back his laughter, "By the way, what are you trying to say?"
"That's right, Your Majesty," Wendy flipped open the record book in her hand, "According to the records of the previous year, today should be Lightning's coming-of-age day."
