I Made Scientific Magic

  Chapter 528 Powerful Brick Flying, Dennis' Explosive Thruster

   One hour later, in the capital, Lin En, who stepped into the Academy of Magic, was warmly received by Tim, the vice president. After Vittorio left, he acted as the dean temporarily.

  When he learned that Lynn was looking for Dennis, Tim was even more bitter.

"Speaker Lynn, you'd better persuade Master Dennis by the way this time. Originally, his propeller plane was doing well, and the upper limit of the maximum speed was constantly raised. The results are very gratifying, and the maximum cruising speed is already close to 400. Kilometers per hour, and I don’t know why I went crazy and suddenly turned around to study an explosive propulsion device..."

   Originally, the Alchemy Research Institute was supportive of Dennis's new attempt, but Dennis' explosive propulsion device exploded just like its name...

   In the past year, the research room assigned to Dennis has not been silent for a single day, ranging from constant explosions to the destruction of the research room.

  Although it is common for accidents to occur during magic research, the frequency is too high!

  The continuous noise has seriously disturbed the research of other wizards, not to mention that personnel injuries are also a big problem. There are more than 60 formal wizards who have been injured, and more than 100 apprentices...

   You must know that the kingdom is currently short of manpower, and it is tempting to split every official wizard in half to use them. Many people have multiple jobs, and a large number of wizard injuries will not affect the progress of a project.

  Listening to Tim's constant complaints, Lynn was also quite surprised. Even if he was studying jet planes, he wouldn't explode with such a terrifying frequency. Now even he was a little uncertain about what Dennis was doing.

It was a large workshop with a very simple construction, and there was only one frame there—according to Tim, there was no need to make too many decorations, as long as the walls were strong enough, and it was useless to build them too beautifully. It might explode someday.

  Tim’s idea is undoubtedly very insightful, because just as the two of them walked to the door of the workshop, the sound of a violent explosion came from inside, the door burst directly, and a strong explosion shock wave greeted them.

A piece of sharp metal fragment was mixed in the shock wave, and it was flying towards them at an extremely fast speed, but the moment it reached in front of them, the speed of the metal fragment suddenly changed from extremely fast to extremely slow, and finally hovered in the air .

  Lin En stretched out his hand to pinch the fragment in his hand, and then stepped into it.

  The interior of the entire alchemy workshop looks smoky, and the ground, walls, and ceiling have been potholed under the influence of the aftermath of several explosions, and the original appearance can no longer be seen.

   "Sure enough..." Tim followed Lynn into the room and shook his head.

  If Dennis hadn’t made outstanding contributions to the improvement of steam engines, internal combustion engines, and propeller fighters, many members of parliament had a glimmer of hope for his new achievements, this dangerous research and development project would have been stopped long ago.

  Because of the explosion that just happened, the entire alchemy workshop was in chaos. Fortunately, the accident happened not once or twice, and no one was injured this time.

   "Speaker Lynn?"

  An alchemist soon discovered Lynn and Tim who had entered the door. After learning of their intentions, he immediately notified Dennis to go.

  The two didn't wait long. After receiving the report, Dennis quickly brought people over. Everyone was ashamed, but their expressions were extremely excited.

  Seeing Lynn and Tim, Dennis pulled their sleeves and said happily. "Quick, quick, you are here just in time! My research is successful, my research is successful!"

   Tim, who was about to make a mockery, swallowed the words that came to his lips, and turned into a look of surprise. Could it be that Dennis really researched that explosive thruster?

  Delighted, Dennis took the two of them to the inside of the workshop, and showed them his new achievement, a propeller about two meters long and 40 centimeters in diameter.

  It's just the middle half, which is rolled outwards like a twist, and the explosion just now obviously came from here!

   "Is this what you call success?" Tim pointed at the badly damaged propeller in front of him and said with a strange expression.

   "Of course it was a success. You must know that this time it ran for a minute, a full minute!" Dennis's voice raised several degrees, and his voice was trembling with excitement.

   This time it didn't explode directly, but started to run. It was a breakthrough from zero to one, which showed that they were very close to the finished product!

   "I'm afraid it's still far away." Tim was speechless, what can one minute do? This is simply a waste of precious human and material resources...

  Dennis didn't pay attention to Tim's meaning at all. While directing the halfling and the alchemist to inspect the propeller and sum up the failure experience, he explained the design concept of the new propeller to Lynn endlessly.

  Traditional propeller aircraft converts the rotational power of the engine into propulsion. As the propeller continues to rotate, the blades will push a large amount of air backwards, generating a forward force on the blades...

  But Dennis believed that the efficiency of relying on wind power was too low, and as the speed continued to increase, he also vaguely noticed the limit, so he decisively turned to research a newer type of propulsion device.

  And what he wants to use this time is the shock wave generated by the explosion!

This is not impossible. In fact, they have widely used this force in weapons. For example, bullets and artillery rely on the impact force generated by the explosion of gunpowder to attack the enemy at high speed, and even internal combustion engines rely on internal powered by the combustion reaction.

  This fully shows that the explosion is the first driving force!

   "You're crazy, Dennis, the resulting fighter is a walking bomb! It might be more appropriate to call it a suicide aircraft!" Tim rolled his eyes.

   "As long as there are materials that are strong enough to withstand high temperatures and impact, plus a reasonable structure that can maximize the impact of this impact, it will have no problems!" Dennis said firmly.

  His experiment undoubtedly verified this point. Compared with the violent impact of the explosion, the propulsion provided by the propeller is simply weak!

  Dennis pointed to every part of the thruster and introduced them one by one.

   There are three gas chambers inside the explosive thruster.

The first gas chamber is engraved with an alchemy circle that transforms magic power into oxygen, which will continuously produce pure oxygen, and the second gas chamber is responsible for transporting pure hydrogen, which will be sent together into the first gas chamber at a stable speed through the pipeline. The three gas chambers are mixed and detonated, and finally the high-temperature and high-speed explosive airflow will be ejected from the rear end of the thruster to produce terrifying thrust...

"I have tested that pure oxygen and hydrogen will not generate a combustion reaction, so the first and second gas chambers are safe, and the pipeline filled with gas blocks the return path of the explosive gas flow, making it only from The spout at the rear comes out..."

  Dennis explained his design concept in detail and quickly, then turned his head to look at Lynn, and said triumphantly.

   "How is it? Speaker Lynn, how about the explosive thruster I developed?"

   "Well, I can only say...simple, direct, and clear!" After listening to Dennis' description, Lynn forced these words out of his mouth.

  Dennis’s design principle is actually only four words—Li Da Brick Fly!

  Simple to a little too outrageous!

  When designing the aircraft, the reason why he considered propeller fighters instead of jet fighters was because the production of jet engines was very difficult.

Before he arrived at the Alchemy Research Institute, he was still a little puzzled. How did Dennis solve so many problems a year ago? It turned out that Dennis didn't intend to solve these problems at all. The things he created were between jet engines and rockets. between the thrusters.

   This thing is not impossible to use, but just like what Dennis said, how to make materials that can withstand high temperature and impact is a huge problem.

  The power of hydrogen-oxygen mixed detonation is terrifying, and its danger can be seen from the degree of destruction of this alchemy workshop.

  Lin En's praise obviously made Dennis extremely happy. This is the joy of the achievement being recognized, not to mention the approval of this magic star.

  A group of alchemists, Lydia, Darren and dozens of other halflings were nervously carrying out the final debugging and testing work, speaking and reporting from time to time.

   "Everything is normal in the hydrogen-oxygen mixed delivery circle!" "There is no problem with the first air chamber." "There is some damage inside the second air chamber. It may be that metal fragments caused by the explosion entered the air chamber..."

"The inner wall of the metal here is seriously damaged. We have used the strongest metal and reinforced the fire protection circle. I didn't expect that it still couldn't withstand the high temperature and pressure brought by the explosion..." Lydia raised her hand high, originally His fair cheeks were covered with oil and dust, making them look pitch black.

   "It seems that the problem of the failure last time should appear here!" Listening to the reports of the alchemists, Dennis kept nodding, and then continued. "Then reduce the fuel delivery speed by 30% this time, adjust the ratio of hydrogen-oxygen mixed combustion, and try again, we are very close to success!"

  Lydia nodded excitedly. Although Dennis had said similar words hundreds of times during this period, the experiment just now was different from the previous failure, because the explosive propeller did work.

  Although it exploded again in only a minute, at least it saw the dawn of completion!

  Dennis took a deep breath, and secretly prayed that he would be successful this time. This is the key to the future research and development funds and the continued development of the explosive propulsion...

With the joint efforts of a group of halflings, the two-meter-long cylindrical metal propeller was quickly reassembled, and then ten alchemists used magic to connect the joints, put the counterweight, and install the propeller. On the upper wing, one of the simplest mimic flight devices has been completed.

   "The three hundred and sixty-seventh experiment, get ready to start!" Dennis said with great anticipation.

Hearing this, a group of halflings who were still gathered near the propeller evacuated to the protective wall fifty meters away as quickly as possible, even Lydia, who had become a wizard, and other alchemists were also evacuated. He retreated ten meters, and blessed himself with several protective spells.

  Dennis was very confident in this experiment, and he had the means of self-protection, so he didn't move at all.

  Lin En did not retreat, even if there was an experimental accident, it was impossible to hurt him.

  Tim originally wanted to hide, but seeing that neither Lynn nor Dennis moved, he had to stand still, and secretly comforted himself that he was a great wizard anyway, so he shouldn't be killed by the bomb...

After everyone hid, Dennis pressed the start button, and as the alchemy circle in the propeller was activated, a large amount of magic power was converted into a specific ratio of hydrogen and oxygen, which was poured into the third cylinder Instantly detonated.

  An eardrum-shattering roar sounded in the workshop, and the entire propeller shook violently, and then hot tongues of flame gushed out from the tail end of the propeller.

  Under the strong impact of the explosion, even the fixing device below was creaking, and Tim's heart went directly to his throat, for fear that this thing would explode directly.

  Lin En's domain has also been expanded, ready to deal with the worst situation at any time, Lydia and the others are also staring at the vibrating propeller intently.

  One second, ten seconds, thirty seconds, sixty seconds...

   A minute passed quickly, and although the metal on the outside of the thruster had turned red in the scorching heat, the expected explosion did not occur!

   "Successful, we really succeeded!" An alchemist shouted immediately, his face full of ecstasy.

  The rest of the wizards were too excited to contain themselves, and Lydia was even more excited and cheered.

  Dennis is undoubtedly the most excited one. The idea of ​​using the explosion shock wave to propel has long been in his mind. Now after a full year and a half of hard work, he finally turned this initial idea into a reality!

   "What's the speed? What's its speed?" Dennis asked the alchemist who was in charge of the test eagerly.

  A thrust detection device is installed under the thruster, which can easily judge the thrust strength provided by this thing.

   "About seven hundred kilometers per hour!" The alchemist's face was full of surprise.

   "It's fully doubled... fully doubled!" Dennis' left fist hit the right palm heavily, and he muttered excitedly.

Tim's eyes were rounded, full of disbelief, and Lynn was also amazed. He originally thought it was too early to engage in jet aircraft, but now Dennis taught him a lesson and told him with practical actions, what It's called solving problems with magic and alchemy!
