The fire moon is coming, and the huge sun is flying in the sky.
Even in this country located in the northern part of the mainland, some areas have begun to feel "hot summer".
Gao Wen turned the information in front of him to the last page, and the charts and data on the information slowly settled in his mind. After a few seconds of thinking, he raised his head and looked at Rebecca and Maggie in front of him: "So The last few attempts to break the 'missile limit' have failed?"
"...Yes, they all failed," Rebecca said with her head down, extremely frustrated, "Whether it is to increase the thrust of the driving array or change the layout of the wind force field, all methods are useless. The details of each failure I have sorted out the records, which are the ones you just saw."
"Hmm... I saw it," Gao Wen frowned, and glanced at the stack of documents that he had placed on the table. A long-lost sense of unknown and contradiction was seeping out from the lines in the document, stirring him. A high-speed mind, "And all tests encountered similar problems in the final stage of acceleration... The magic field that maintains the acceleration was suddenly greatly disturbed, the output dropped sharply, and the aircraft slowed down accordingly..."
"It feels like suddenly crashing into a chaotic and extremely powerful 'magic quagmire'," Maggie, who personally carried out most of the flight test missions, immediately reported her feelings at the time, "No matter how big the previous maintenance No effort will be quickly disintegrated by the quagmire, and the speed will not increase."
Gao Wen fell silent for a short while, thinking in silence.
Missile limit, the speed limit that all physical flying objects will face. After approaching this limit, the flying object will be captured by an invisible but powerful "mire". If it is a flying device driven by magic power, it will appear as magic power to maintain thrust If it is a bird or beast that does not rely on magic to fly in nature... the reason is not clear, but they cannot break through this "barrier" without exception.
This is a very familiar phenomenon, so familiar that Gao Wen couldn't help but think of the difficulties that high-speed aircraft on Earth once faced: the sound barrier, but...
He sighed softly, raised his head, and said as if talking to himself: "The currently known speed of sound in the atmosphere is..."
"According to the data measured by the scholars in the north, the speed of sound in the atmosphere is 322 meters per second near sea level and around freezing point." Rebecca said immediately.
The northern border was the magical holy land of Anzu in the past. Due to the influence of the Wilder family, a large number of outstanding mages and scholars gathered in that cold place. In order to explore the mysteries of various magical phenomena, even the mages of the old era would I will do a series of research on nature, so concepts such as the speed of sound in the atmosphere, air pressure, and the melting and boiling points of various substances have always existed among upper-level intellectuals, and the data are still very accurate.
At this moment, a precise number among them... is provoking Gawain's nerves like a nasty little devil.
In this world, the speed of sound in the atmosphere at standard pressure and freezing temperatures is 322 meters per second—two-thirds of the missile limit.
The speed barrier that Rebecca's aircraft encountered was not a sound barrier, but another completely unknown thing.
In fact, the "sound barrier" that has plagued scientists on Earth for a long time is not a big problem in this world at all, and has even been solved without knowing it-although the existing "Dragoon" aircraft cannot It exceeds the speed of sound, but some accelerated flight devices manufactured by Rebecca in the laboratory environment have successfully broken through this barrier several times.
Laboratory data showed that the wind force field spells originated from the elves could almost perfectly solve a series of problems caused by atmospheric resistance—even though the "Dragon Cavalry" and some other flying machines had no concept of aerodynamics at all in Gawain's eyes, But the parts visible to the naked eye of the aircraft are not the real "aerodynamic shell" when they are flying. What really deals with the atmospheric environment is a layer of force field surrounding the aircraft, and that force field has perfect aerodynamic properties , and can even resolve the shock waves and other problems faced during supersonic flight. Coupled with the powerful power brought by the dragon language propulsion array, it is infinitely easier for aircraft in this world to break through the sound barrier than Gao Wen once imagined.
Of course, this does not mean that the technology to break through the sound barrier is rudimentary—the elves’ wind element force field spells have a history of thousands of years, and have gone through a long and arduous research and development process. It does something unexpected, but the technology itself didn't just fall from the sky.
In any case, the speed of sound is not the real difficulty in front of Cecil's aircraft technology, the real difficulty... is the mysterious missile limit after breaking through the speed of sound, or in the terms of the elves, it is called the "entity flight speed barrier".
And Gawain knew nothing about it.
He can only judge from intuition and existing experimental phenomena that the speed barrier has a great probability to be independent of air resistance, air shock waves and other factors. It may involve some characteristics of the magical environment of this world, and may even involve some more fundamental issues.
"Currently, the tests we have done in the origin laboratory have seriously deviated from the experimental results in the real world," Rebecca said boldly, seeing that Gao Wen remained silent for a long time, "in short... The limits of real-world missiles are beyond what Origins Labs can 'understand'. So I plan to focus my next experiments on high-speed aircraft on the real world."
"Correct judgment," Gao Wen nodded lightly, "Then do you have any ideas for the next step?"
Rebecca looked at Maggie next to her, and then at Gawain cautiously. After obvious hesitation, she boldly took a step forward: "I want to test the speed limit with cannonballs..."
Gao Wen raised his eyebrows: "Cannonball?"
"It's not a real shell either, but the principle is the same," Rebecca waved her hand, "Now all our tests are to put the propulsion device on the aircraft, and the results are also obvious. When the speed is close to the limit of the missile, those The propulsion unit is nearly useless, so I'm going to change my mind and launch an unpowered entity with a fixed propulsion unit to see what happens...
"In this way, the propulsion device itself does not involve the speed limit, and theoretically it will not be affected by the 'magic quagmire', it should be able to continue working until the end, accelerating the flying entity to the limit that the device can withstand.
"Of course, there are many birds and beasts in nature that do not have magical powers, and their speed cannot exceed the limit of missiles, but I think this is only because their flesh and blood have limits—if a solid shell is made of steel, the situation will definitely will be different."
Gao Wen's originally slightly frowned brows gradually relaxed as Rebecca's narration, and he listened to the other party's thoughts with great interest: "Then what exactly are you going to do?"
"I want to build a bigger acceleration track, use more and more powerful repulsion devices, use more powerful overloaders, and if necessary, this track can even be a one-off - I want to use it to Launch a cannonball, the cannonball itself does not carry any magical effect except for the wind rune, I want to see if it can break through the missile limit."
Gao Wen stroked his chin with his finger, and began to help Rebecca to improve his ideas: "Then have you considered that the wind rune on the shell will also be affected when the missile limit is approaching, causing the shell to be 'trapped' by the magic quagmire? "
"So the acceleration trajectory must be long, and the power of the runes must be high. Even if the wind rune on the shell disintegrates, the acceleration trajectory must continue to push the shell forward," Rebecca said immediately, "If it is not possible, we will Build a vacuum pipe to accommodate the entire device, so that the wind rune can be removed altogether, and the cannonball can be simplified into an iron lump. Coupled with the vacuum environment, perhaps a better acceleration effect can be obtained... "
Unsurprisingly, the iron-headed girl came up with a very powerful idea of miracles.
But Gao Wen had to admit that Rebecca's idea of "working hard to produce miracles" is really reasonable, and it is the best idea at this stage. Even if he makes some suggestions and optimizations, he can only do it based on this idea Some tinkering.
However, after thinking about it briefly, he still seemed to mention it casually: "There is just one problem. The cost of doing this may not be low. Have you told Hetty?"
"Not yet," Rebecca rubbed her head immediately, her voice lowered by 20%, "Such a large set of acceleration orbits, coupled with supporting energy supply, observation, safety facilities, and may have to build a vacuum shell , after the cost is calculated, there is a high probability that my aunt will chase and beat you... That's why I came to you first, thinking... "
Her voice became smaller and smaller, and in the end it simply turned into a whisper of a person.
Gawain couldn't help laughing suddenly, looking at Rebecca, who was trembling with the conspiracy exposed, and nodded under the surprised gaze of the other party: "I have already approved this project, Chartered."
"Really...really?" Rebecca stared as if she still couldn't believe it, "Is that what you agreed to?"
"This project is very important, and the results produced in the later stage may exceed everyone's expectations. I think it is necessary to increase investment," Gao Wen said with a smile, "But I also have some suggestions. We can ignore the vacuum shell for now. By optimizing the shape of the 'cannonball' itself, we... ”
A gust of invisible wind suddenly blew into the study, and a familiar aura appeared beside the desk. Gawain immediately stopped and looked at the seemingly empty side: "What's the matter? Come here in such a panic."
Seeing Gawain's reaction, Rebecca and Maggie had already guessed who was coming, and the figure of Amber really emerged from the air the next moment. He bent down and whispered a few words.
Rebecca watched as her always dignified and dependable ancestor visibly stiffened for the next few seconds.
In the next second, Gao Wen stood up abruptly, with a terrifyingly solemn expression.
"Rebecca, I've approved the project, you can start preparing your accelerator," Gao Wen said quickly, and then looked at Maggie, "Maggie, I need your help."
Maggie immediately lowered her head: "Of course, just follow your orders."
"We are going to the Plain of the Holy Spirit immediately, Fort Solin."
Rebecca faintly sensed something from Gawain's attitude, and immediately asked, "My lord ancestor, what happened?!"
Gawain glanced at Rebecca quietly, took a breath slowly, and let it out slowly.
"Norris is dying," he said slowly.
"Norris?" Rebecca's eyes widened instantly. At first, she seemed to have not understood the meaning of her ancestor's words. It took two seconds for her to realize that she took a step forward subconsciously, "I want to..."
Gawain looked at Rebecca, and saw the stubbornness that suddenly appeared in the other's eyes—this child usually has some problems with her personality, but she rarely showed such stubbornness when facing Gawain or Hetty. manner.
He recalled that Norris was from Old Cecil, and was one of the eight hundred people Rebecca had saved with all her might.
Norris, who was born as a farmer, eventually became the Minister of Agriculture of the Empire, and it was also inseparable from the recommendation of Hetty and Rebecca.
After a moment of silence, Gawain nodded: "Yes."
Rebecca showed an expression of relief, and immediately smiled to express her gratitude to her ancestors, but soon her smile disappeared again, and a sad and worried expression spread across her face.
Gawain's brows gradually frowned. He recalled the news from Solinburg in the recent period, thinking about some things mentioned by the other party when he spoke with Bertila last time, and gradually fell into deep thought.
After a while, he nodded slightly to Amber beside him: "You go to the north bank..."
It is said that returning from the dead is a miracle.
Gao Wen felt that he had achieved this miracle.
So... maybe it's time for him to perform another miracle.
