Chapter 863： On the way

The moon of fire is approaching, and the giant sun volleys.

Even in this country located in the north of the mainland, some areas have begun to feel the "hot summer".

Gao Wen turned the information in front of him to the last page. The graphs and data on the information slowly settled in his mind. After a few seconds of thinking, he looked up and looked at Rebecca and Maggie in front of him: "So The last few attempts to break through the 'missile limit' have failed? "

"... Yes, they all failed," Rebecca said with her head down, frustrated. "Whether it is to increase the thrust of the drive array or change the layout of the wind force field, various methods are useless. Every time it fails I have sorted out the detailed records, the ones you just saw. "

"Hmm ... I saw it," Gao Wen frowned, glanced over the pile of documents that had been placed on the table, a long-lost sense of unknownness and contradiction was seeping from the lines of the document, agitating His high-speed head, "and all tests encountered similar problems in the final stage of acceleration ... the magic field to maintain acceleration was suddenly greatly disturbed, the output plummeted, and the aircraft slowed down ..."

"It felt like I was suddenly bumped into a chaotic and extraordinarily powerful 'magic quagmire,'" Maggie, who personally performed most of the test flight missions, immediately reported her feelings at that time. Every effort will be quickly disintegrated by that quagmire, and the speed cannot be increased. "

Gao Wen was silent for a moment, 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 the invisible but powerful "mud". If it is a magic-driven flying device, it will behave as a magic force to maintain thrust. The field is disintegrating. If it is a bird or animal that does not rely on magic to fly in nature ... Although the reason is not clear, they can't break through this "barrier" without exception.

This is a very familiar phenomenon. It is so familiar that Gao Wen could not help but think of the obstacle that high-speed aircraft on the earth once faced: the sound barrier, but ...

He sighed softly, raised his head, and said as if to himself: "The currently known speed of atmospheric sound is ..."

"According to data measured by scholars from the northern border that year, the speed of sound in the atmosphere near sea level and around freezing point is 322 meters per second," Rebecca said immediately.

The northern border was the magical sacred place of Anzu in the past. Due to the influence of the Wilde family, a large number of excellent mages and scholars concentrated in that cold place. In order to explore the mysteries of various magic phenomena, even the mages of the old age also A series of researches will be done on nature, so concepts such as atmospheric sound velocity, air pressure, and melting points of various substances have always been among the upper intellectuals, and the data is still very accurate.

At this moment, one of these precise numbers ... was arousing Gao Wen's nerves like an annoying little devil.

In this world, the atmospheric sound velocity at standard pressure and freezing point temperature is 322 meters per second-two-thirds of the missile limit.

The speed barrier encountered by Rebecca ’s aircraft is not a sound barrier, but another completely unknown thing.

In fact, the "sound barrier" that has plagued scientists on the planet for a long time is not a big problem in this world, and it has even been solved unknowingly-although the existing "Dragon Cavalry" aircraft still has It is impossible to exceed the speed of sound, but some accelerated flight devices Rebecca has made in the laboratory environment have successfully breached this barrier several times.

Laboratory data show that the wind force field spells derived from the elves can almost perfectly solve a series of problems caused by atmospheric resistance-although the "dragon cavalry" and some other flying machines have no concept of aerodynamics in Gao Wen's eyes. But the visible part of those aircraft is not their true "aerodynamic shell" during flight. What really deals with the atmospheric environment is a layer of force field surrounding the aircraft, and that layer of force field has perfect aerodynamics. Features, can even solve the problems such as shock waves to face when flying at supersonic speeds, coupled with the powerful power brought by the Dragon language propulsion array, this world's aircraft breakthrough sound barrier is much simpler than Gao Wen had imagined.

Of course, this does not mean that the technology to break through the sound barrier itself is crude—the elves' wind element force field spells have a history of thousands of years, and they have also experienced a long and arduous R & D process, it is just in the magic guide technology The system played an unexpected function, but the technology itself did not fall from the sky.

In any case, the speed of sound is not the real obstacle to stop the Cecil aircraft technology. The real difficulty ... After breaking through the speed of sound, it is the mysterious missile limit, or in the spirit's parlance, called the "physical flying speed barrier".

Gao Wen knew nothing about it.

He can only start from intuition and existing experimental phenomena, and judge that this speed barrier has a great probability that has nothing to do with air resistance, air shock, and other factors. It may involve some characteristics of the magic environment of the world, and may even involve some More essential issues.

"At present, the tests we have done in the Origin Lab have very serious deviations from the experimental results in the real world," said Rebecca, looking at Gao Wen for a long time without speaking, and boldly proactively said, "In short, it is ... … The missile limit in the real world is beyond what the Origin Lab can 'understand.' So I plan to focus the next experiments on high-speed aircraft in the real world. "

"Correct judgment," Gao Wen nodded slightly. "Do you have any ideas next?"

Rebecca took a look at Maggie next to him, and then took a careful look at Gao Wen. After obvious hesitation, she took a bold step forward: "I want to test this speed limit with shells ..."

Gao Wen raised an eyebrow: "Cannonball?"

"It's not really a cannonball, but the principle is similar," Rebecca waved. "All our tests now place the propulsion device on the aircraft, and the results are also very obvious. When the speed is approaching the missile limit, those The propulsion device is 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 in theory it will not be affected by that‘ magic quagmire ’. It should be able to continue working to the end and accelerate the flying entity to the limit that the device can withstand.

"Of course, there are also many birds and animals in the nature that do not possess magic. Their speed cannot exceed the missile limit, but I think this is only because their flesh and blood have limits-if a solid shell is made of steel, the situation is It must be different. "

Gao Wen's slightly frowned brow gradually stretched out as Rebecca recounted. He listened with interest to the other party's thoughts: "What are you going to do?"

"I want to build a larger 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 Let ’s fire a shell. The shell itself does not carry any magic effects except wind runes. I want to see if it can break the missile limit. "

Gao Wen rubbed his chin with his fingers and began to help Rebecca to perfect his thoughts: "Then you have considered the wind runes on the shells when the missile limit is approaching, which will cause the magic quagmire to" stuck "the shells? "

"So the acceleration trajectory must be long, and the rune power must be large, even if the wind rune on the cannonball is disintegrated, the acceleration trajectory must continue to push the cannonball forward," Rebecca said immediately. "It's really impossible, we will Build a vacuum pipe to house the entire device, so that you can simply remove the wind runes, simplify the cannonball into an iron goblet, and add a vacuum environment, maybe you can get better acceleration ... "

Unsurprisingly, the head iron girl came up with a pretty miracle idea.

However, Gao Wen had to admit that Rebecca ’s idea of ​​“striving a miracle” really makes sense, and it is also the best idea at this stage. Even if he makes some suggestions and optimizations next to it, he can only do so in this way. Some tinkering.

However, after a brief thought, he still seemed to casually say: "It's just a problem. I'm afraid the cost is not low. Did you talk to Herty?"

"Not yet," Rebecca immediately felt her head, her voice was 20% lower. "Such a large set of acceleration orbits, coupled with supporting energy, observation, and safety facilities, and may have to build a vacuum shell. After the cost is calculated, it is likely that I will be chased by my aunt ... so I came to you first and thought ... "

Her voice was getting weaker and quieter, and she became a mumbling person in the end.

Looking at Rebecca who was uneasy before the conspiracy was revealed, Gao Wen suddenly couldn't help but laugh. In the surprised eyes of the other side, he nodded: "I have approved this project and licensed it."

"Really ... really?" Rebecca stared, as if still unbelievable. "You just allowed it?"

"This project is very important, and the results produced in the later stage may not 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. By optimizing the shape of the 'cannonball' itself, we will ... "

An invisible wind suddenly blew into the study, and the familiar atmosphere appeared beside the desk. Gao Wen immediately stopped and looked at the seemingly empty side: "What's wrong? Come here in such a panic."

Rebecca and Maggie had already guessed the person who had seen Gao Wen ’s response, and the figure of Amber really emerged from the air at the next moment. The latter nodded briefly to Rebecca and was next to Gao Wen Leaned down and whispered a few words.

Rebecca saw that her always majestic and ancestor had a stiff expression in the next few seconds.

The next second, Gao Wen stood up horrifiedly, with a somber look.

"Rebecca, I have approved the project. You can start preparing your accelerator," Gao Wen said quickly, and looked at Maggie aside, "Maggie, I need your help."

Maggie immediately lowered her head. "Of course, you do."

"We're heading to the Plain of the Holy Spirit immediately, Solingborg."

Rebecca noticed something from Gao Wen's attitude, and immediately asked: "Master, what happened?"

Gao Wen took a quiet look at Rebecca, took a slow breath, and then slowly spit it out.

"Norris is critically ill," he said slowly.

"Norris?" Rebecca's eyes widened for a moment, as if she hadn't figured out what the ancestors said in the beginning. She responded only two seconds later and took a subconscious step forward. "I want to ... "

Gao Wen looked at Rebecca, watching the sudden emancipation in the other's eyes-the child's usual personality was a problem, but she rarely showed such perseverance in the face of Gao Wen or Hetty. Attitude.

He recalled that Norris was from the old Cecil and was one of the 800 people rescued by Rebecca.

Norris, a farmer who eventually became the empire's agriculture minister, was also inseparable from the recommendations of Herty and Rebecca.

After a moment of silence, Gao Wen nodded: "Yes."

Rebecca showed a clearly relieved expression, and immediately smiled to express her gratitude to her ancestors, but soon her smile disappeared again, and her sad and worried expression spread on her face.

Gao Wen's brow gradually wrinkled. He recalled the news from Solingborg in recent time, thinking about some of the things mentioned by the other party when he talked with Bertila last time, and gradually fell into contemplation.

After a moment, he nodded slightly to the amber beside him, "You go to the North Shore ..."

It is said that resurrection is a miracle.

Gao Wen felt that he had achieved this miracle.

Well ... maybe he should do another miracle.
