The fire moon is coming, and the giant sun is rising in the sky.
Even in this country located in the north of the mainland, some areas have begun to feel like a "hot summer".
Gawain turned to the last page of the information in front of him. 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 Rebbe in front of him. Ka and Maggie: "So the recent attempts to break through the 'missile limit' have all failed?"
"...Yes, they have all failed," Rebecca lowered her head, feeling particularly frustrated. Said, "Whether it is increasing the thrust of the drive array or changing the layout of the wind force field, all methods are useless. I have compiled detailed records of every failure, the ones you just saw."
"Well...I saw it," Gawain frowned and glanced at the pile of documents that he had placed on the table. A long-lost sense of unknown and contradiction was seeping from the lines of the documents. came out, stirring his fast-moving mind, "And all tests encountered similar problems in the final stage of acceleration... The magic field that maintains acceleration was suddenly greatly disturbed, the output dropped sharply, and the aircraft slowed down..."
"It felt like suddenly crashing into a chaotic and extremely powerful 'magic quagmire'," Maggie, who personally performed most of the test flight missions, immediately reported her feelings at the time. , "No matter how much effort you maintain before, it will be quickly disintegrated by the quagmire, and the speed will never increase."
Gawain fell silent briefly, thinking in silence.
The missile limit is the speed limit that all physical flying objects will face. After approaching this limit, the flying object will be captured by the invisible but powerful "quagmire". If it is a flying device driven by magic, then It will be manifested as the collapse of the magic field that maintains thrust. If it is a bird or beast in nature that does not rely on magic to fly... Although the reason is unclear, they are unable to break through this "barrier" without exception.
This is a very familiar phenomenon, so familiar that Gawain couldn't help but think of the difficulties that high-speed aircraft on Earth have faced: sound barriers, but...
He sighed softly. He raised his head and said as if talking to himself: "The currently known speed of atmospheric sound is..."
"According to the data measured by scholars in the north, near sea level, The speed of sound in the atmosphere at around freezing point is 322 meters per second," Rebecca said immediately.
The North 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 if The mages of the old era would also conduct a series of studies on nature. Therefore, concepts such as atmospheric sound speed, air pressure, melting and boiling points of various substances, etc., have always been available among upper-class intellectuals, and the data are still very accurate.
At this moment, a certain precise number... is stirring up Gawain's nerves like an annoying little devil.
In this world, standard gasThe speed of atmospheric sound at high pressure and freezing temperature 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 something completely unknown.
In fact, the "sound barrier" that has troubled scientists on earth for a long time is not a big problem in this world at all, and has even been solved without even realizing it - although the existing The "Dragoon" aircraft cannot yet exceed the speed of sound, but some acceleration flight devices created by Rebecca in a laboratory environment have successfully broken through this barrier several times.
Laboratory data shows that the wind force field spell originated from the elves can almost perfectly solve a series of problems caused by atmospheric drag - although the "Dragoon" and some other flying machines are in Gawain's eyes There is no concept of aerodynamics at all, but those parts of the aircraft that are visible to the naked eye are not the real "aerodynamic shell" when they fly. What really deals with the atmospheric environment is a layer of force fields surrounding the aircraft, and that layer of force The field has perfect aerodynamic properties and can even resolve problems such as shock waves faced during supersonic flight. Coupled with the powerful power brought by the dragon language propulsion array, the aircraft in this world can break through the sound barrier far more than Gawain ever imagined. It's infinitely simpler.
Of course, this does not mean that the technology itself for breaking the sound barrier is crude - 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 just happened to play an unexpected role in the magic technology system, but the technology itself did not fall from the sky.
In any case, the speed of sound is not the real difficulty that stands in the way of Cecil aircraft technology. The real difficulty... is after breaking through the speed of sound, it is the mysterious missile limit, or in the elves' parlance, it is called "Physical flight speed barrier".
And Gawain knows nothing about it.
He can only judge based on intuition and existing experimental phenomena that this speed barrier has a high probability to have nothing to do with air resistance, air shock waves and other factors. It may involve some aspects of the magical environment of this world. characteristics, and may even involve some more essential issues.
"The current tests we are doing in the Origin Laboratory have very serious deviations from the experimental results in the real world," Rebecca saw that Gawain had not spoken for a long time, so she boldly said proactively, "In short... the missile limits in the real world are beyond what the Origin Laboratory can 'understand'. So I plan to focus the next tests on high-speed aircraft on the real world."
"Correct judgment," Gawain nodded slightly, "Then what ideas do you have next?"
Rebecca looked at Maggie next to her, and then looked at Gawain cautiously After a quick glance, he took a bold step forward after obvious hesitation: "I want to try using cannonballs to test this speed limit..."
Gaowen raised his eyebrows: "Cannonballs?"
p>“It’s not a real cannonball, 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 approaches the limit of the missile, those propulsion devices are almost scrapped, so I plan to change my mind and use a fixed propulsion device to launch an unpowered entity and see what happens...
"In this way, the propulsion device itself does not involve the speed limit, and theoretically Without being 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 also many birds in nature that do not possess magical powers. Beasts, their speed cannot break through the missile limit, but I think this is just because their flesh and blood has limits - if a solid cannonball is made of steel, the situation will definitely be different. "
Gao Wen's slightly frowned brows gradually relaxed as Rebecca spoke. He listened to the other party's thoughts with interest: "Then what are you going to do specifically? ”
“I want to build a larger acceleration orbit, use more and more powerful repulsion devices, and use more powerful overloaders. If necessary, this orbit can even be a Sexually - I want to use it to fire a cannonball. The cannonball itself does not carry any magical effects except wind runes. I want to see if it can break through the missile limit. "
Gawain rubbed his chin with his fingers and began to actively help Rebecca improve her idea: "Then have you considered that when the missile is approaching its limit, the wind runes on the cannonballs will also be affected, leading to a magic quagmire' Trapped 'cannonball situation? ”
“So the acceleration track must be long and the rune power must be high. Even if the wind runes on the cannonball are disintegrated, the acceleration track must continue to push the cannonball forward,” Rebecca immediately Said, "If it doesn't work, we will build a vacuum pipeline to house the entire device. In this way, we can simply remove the wind runes and simplify the cannonball into an iron lump. Coupled with the vacuum environment, we may be able to get a better acceleration effect." ..."
Unsurprisingly, this tough-headed girl came up with a rather powerful idea that would produce miracles.
But Gawain had to admit that Rebecca's "strong power" The idea of "making a miracle" is indeed very reasonable, and it is also the best idea at this stage. Even if he makes some suggestions and optimizations on the side, he can only make some tinkering with this idea.
However, after thinking briefly, he still said it seemingly casually: "There is just one problem. The cost of doing this may not be low. Have you told Hetty? "
"Not yet," Rebecca immediately touched her head and her voice became 20% quieter. "Such a large set of acceleration orbits, coupled with supporting energy supply, observation, and safety facilities, And you may have to build a vacuum shell. After the cost is calculated, there is a strong chance that your aunt will chase you and beat her up... That's why I came to you first, thinking..."
Her voice became increasingly louder. The smaller it is, in the end it will simply become one person’s DidiGu Gu Gu.
Looking at Rebecca, who was uneasy as the conspiracy was exposed in front of her, Gawain suddenly couldn’t help but laugh. In the eyes of the other party’s surprised eyes, he nodded: “I have already approved this project. Franchise."
"Really...really?" Rebecca stared as if she still couldn't believe it. "You just agreed to it?"
"This project is very important. Important, and the results produced in the later period 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 first and optimize the shells 'In its own form, we..."
A gust of invisible wind suddenly blew into the study, and a familiar breath appeared beside the desk. Gawain immediately stopped and looked at the seemingly empty body. Side: "What's wrong? You came here in such a panic."
Rebecca and Maggie already guessed who was coming when they saw Gawain's reaction, and Amber's figure emerged from the air at the next moment. Coming out, the latter simply nodded to Rebecca and the two, then leaned down next to Gawain's ear and whispered a few words.
Rebecca saw that her always majestic and reliable ancestor's expression became obviously stiff in the next few seconds.
The next second, Gawain suddenly stood up, his expression solemn and terrifying.
"Rebecca, I have approved the project, you can start preparing your accelerator," Gawain said quickly, then looked at Maggie aside, "Maggie, I need your help. Busy."
Maggie immediately lowered her head: "Of course, just ask."
"We need to go to the Holy Spirit Plains, Solinburg immediately."
Rebecca faintly noticed something from Gawain's attitude, and immediately asked: "Master Ancestor, what happened?!"
Gawain looked at Rebecca quietly, He took in a breath slowly and exhaled it slowly.
"Norris is critically ill." He said slowly.
"Norris?" Rebecca's eyes widened for a moment. At first, she seemed not to understand the meaning of her ancestor's words. It took her two seconds to react, and she subconsciously took a step forward. , "I want to..."
Gawain looked at Rebecca and the sudden stubbornness in her eyes - this child usually has some personality problems, but she rarely This stubborn and willful attitude appears when facing Gawain or Hetty.
He recalled that Norris was from the old Cecil and was one of the eight hundred people who Rebecca had saved with her life.
The fact that Norris, who was born as a farmer, eventually became the Minister of Agriculture of the empire was inseparable from the recommendations of Hetty and Rebecca.
After a moment of silence, Gawain nodded: "Okay."
Rebecca showed an expression of obvious relief, and immediately smiled and expressed her gratitude to her ancestors. , but soon her smile disappeared again, and an expression of sadness and worry spread on her face.
Gawain’s browThen he gradually wrinkled as he recalled the news that had come from Solinburg in the recent period, thinking about some of the things that the other party mentioned when he talked to Bertila last time, and gradually fell into deep thought.
After a moment, he nodded slightly to Amber beside him: "Go to the North Shore..."
It is said that resurrection from the dead is a miracle.
Gawain felt that he had achieved this miracle.
Then... maybe it's time for him to create another miracle.
