An hour later, Lin En, who entered the Magic Research Institute in the Royal Capital, was warmly received by Tim, the vice-president. After Vittorio left, he temporarily took over as the dean.
When he learned that Lynn was here to see Dennis, Tim was even more bitter.
"Speaker Linn, you'd better give Master Dennis some advice this time. Originally, his propeller plane was doing well, and the upper limit of the maximum speed was constantly mentioned. The results were very gratifying. The maximum cruising speed is almost close to 400 kilometers per hour, but I don’t know why I went crazy and suddenly turned around and wanted to research an explosive propulsion device..."
Originally, the Alchemy Research Institute was supportive of Dennis's new attempt, but as a result, Dennis' explosive propulsion device, just like its name, exploded...
In the past year, there has been no quiet day in the research laboratory assigned to Dennis. There have been constant explosions, and the laboratory has been blown up.
Although unexpected situations are common when doing magic research, the frequency is too high!
Not only did the continuous noise seriously disturb the research of other wizards, personnel injuries were also a big problem. There were more than 60 official wizards injured, and the number of apprentices exceeded 100...
You must know that the kingdom is short of manpower now, and it is tempting to break every official wizard in half and use it. Many people have multiple jobs. The injury of a large number of wizards will not affect the progress of a project.
Listening to Tim's constant complaints, Linn was quite surprised. Even if he was studying jet aircraft, they wouldn't explode at such a terrifying frequency. Now even he was a little unsure of what Dennis was doing.
It was a large workshop with a very simple construction, with only one frame there - according to Tim, there was no need to do too much decoration, as long as the walls were strong enough, it was useless to build it too beautifully. It might explode one day.
Tim's idea was undoubtedly very insightful, because as soon as the two of them walked to the door of the workshop, a violent explosion came from inside. The door burst directly, and a strong explosion shock wave greeted them.
A sharp metal fragment was mixed in the shock wave and flew towards them at an extremely fast speed. However, the moment it reached them, the speed of the metal fragment suddenly changed from extremely fast to extremely slow, and finally hovered in the air. .
Linn reached out and held the fragment in his hand, then stepped in.
The interior of the entire alchemy workshop looked smoky. The surface, walls, and ceiling were all pitted under the influence of the aftermath of several explosions, and the original appearance was no longer visible.
"Sure enough..." Tim followed Linn and walked in, shaking his head.
If Dennis had not made outstanding contributions to the improvement of steam engines, internal combustion engines and propeller fighters, which gave many congressmen a glimmer of hope in his new achievements, this dangerous research and development project would have been stopped long ago.
Due to the explosion that just occurred, 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 spotted Lynn and Tim entering the door. After learning their purpose, he immediately notified Dennis.
The two of them didn't wait long. After receiving the report, Dennis quickly brought people over. Everyone looked disgraced, but their expressions were extremely excited.
Dennis, who saw Lynn and Tim, pulled their sleeves and said with great joy. "Hurry, hurry, 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 had really researched that explosive thruster?
Overjoyed, 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 forty centimeters in diameter.
It's just that the middle half is rolled outwards like a twist. The explosion just now obviously came from here!
"Is this what you call success?" Tim pointed at the severely damaged thruster in front of him and said with a strange expression.
"Of course it's a success. You know, it ran for a minute this time, a full minute!" Dennis's voice rose several degrees, and his voice was trembling with excitement.
This time it didn't explode directly, but started running. It was a breakthrough from zero to one, which showed that they were extremely close to the finished product!
"I'm afraid there's still a long way to go." Tim was speechless. What could one minute be enough for? This is simply a waste of precious human and material resources...
Dennis ignored Tim's intention at all. While directing the halflings and alchemists to inspect the thrusters and sum up their failed experiences, he kept explaining the design concept of the new thrusters to Linn.
Traditional propeller aircraft convert the engine rotational power into propulsion. As the propeller continues to rotate, the blades push a large amount of air backward, creating 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 sensed the limit, so he decisively turned to research on 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 made extensive use of this power in weapons. For example, bullets and artillery rely on the impact force generated when gunpowder explodes to attack the enemy at high speed. Even internal combustion engines rely on internal combustion reaction to provide power.
This fully shows that explosion is the first driving force!
"You're really crazy, Dennis. The fighter plane created like this is simply 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 use of this impact, it will not have any problems!" Dennis said firmly.
His experiments undoubtedly verified this. Compared with the violent impact of the explosion, the propelling force provided by the propeller was simply weak!
Dennis pointed at each component of the thruster and introduced it one by one.
This explosive propeller has three gas chambers inside.
The first gas chamber is burned with an alchemical array that converts magic into oxygen, which will continuously produce pure oxygen. The second gas chamber is responsible for transporting pure hydrogen. They will be sent together through the pipeline at a stable speed into the third gas chamber. 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 propeller to produce terrifying thrust...
"I have tested that pure oxygen and hydrogen will not produce a combustion reaction, so the first and second gas chambers are safe, and the pipes filled with gas block the return path of the explosive gas flow, so that it can only pass through The nozzle at the rear end spurts out..."
Dennis explained his design concept in detail and quickly, then turned to look at Lynn and said proudly.
"How about it? Speaker Linn, how about this explosive thruster I developed?"
"Well, all I can say is... simple, direct, and clear!" After hearing Dennis' description, Linn forced these words out of his mouth.
Dennis's design principle actually only has four words - the bricks fly with great force!
It’s so simple that it’s a little too outrageous!
When he was designing the aircraft, he considered propeller fighters instead of jet fighters because jet engines were very difficult to make.
Before arriving at the Alchemy Research Institute, he was still a little confused as to how Dennis had solved so many problems a year ago. It was obvious that Dennis had no intention of solving these problems at all. What he created was somewhere between a jet engine and a rocket. between thrusters.
This thing is not completely useless, but as Dennis himself said, how to create materials that can withstand high temperatures and impact is a huge problem.
The power of the hydrogen-oxygen mixed detonation is very terrifying, and some clues about its danger can be seen from the degree of damage to the alchemy workshop.
Lynn's praise obviously made Dennis extremely happy. This was the joy of having his results recognized, not to mention the recognition of the magic star.
A group of alchemists, Lydia, Darren and dozens of other halflings were nervously carrying out final debugging and testing work, and reporting from time to time.
"Everything is normal in the hydrogen and oxygen mixed transport array!" "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 metal wall here is seriously damaged. We have used the strongest metal and added a fireproof array. Unexpectedly, we still can't withstand the high temperature and pressure caused by the explosion..." Lydia raised her hands high. The originally fair cheeks were covered with oil and dust, making them look pitch black.
"It seems that the problem of the last failure should occur here!" Listening to the reports of the alchemists, Dennis nodded, and then continued. "Then this time reduce the fuel delivery speed by 30%, adjust the proportion of hydrogen and 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 thruster was indeed running.
Even though it only took a minute before it exploded again, at least we saw the dawn of completion!
Dennis took a deep breath and secretly prayed that it would be successful this time. This is the key to future development funds and the continued development of explosive thrusters...
With the joint efforts of a group of halflings, the cylindrical metal propeller, which was more than two meters long, was quickly reassembled. Ten alchemists used magic to connect the joints, put on counterweights, and installed On the wing, the most rudimentary mimic flying device has been completed.
"Experiment 367, get ready to start!" Dennis said with great anticipation.
Hearing this, the halflings who had originally gathered near the thruster evacuated as quickly as possible to the protective wall fifty meters away. Even Lydia, who had become a wizard, and the other alchemists also He stepped back ten meters and cast several protective spells on himself.
Dennis was very confident in this experiment, and he had the means to protect himself, so he didn't move at all.
Lin En did not step back, even if there was an experimental accident, it was impossible to hurt him.
Tim wanted to hide, but when he saw that neither Lin nor Dennis moved, he had to stand still and comfort himself that he was a great wizard after all, so he would not be killed...
After everyone hid, Dennis pressed the start button. As the alchemy circle in the thruster was activated, a large amount of magic power was converted into a specific ratio of hydrogen and oxygen, and was poured into the third cylinder. Detonated instantly.
An eardrum-shattering roar sounded in the workshop, and the entire propeller shook violently, and then hot tongues of fire spurted out from the rear end of the propeller.
Under the strong impact of the explosion, even the fixing device below was creaking. Tim's heart went up to his throat, fearing that the thing would explode.
Lin En's domain has also been expanded, ready to deal with the worst situations at any time. Lydia and others are also staring at the constantly vibrating propeller.
One second, ten seconds, thirty seconds, sixty seconds...
One minute passed quickly. 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 filled with ecstasy.
The other wizards were too excited to control themselves, and Lydia even cheered with joy.
Dennis is undoubtedly the most excited one. The idea of using explosion shock waves for propulsion has long been in his mind. Now after a full year and a half of hard work, he has finally turned this initial idea into a reality!
"What's the speed? What's its speed?" Dennis grabbed the alchemist responsible for the test and asked eagerly.
A thrust detection device is installed below the thruster, which can easily determine the thrust intensity provided by this thing.
"About seven hundred kilometers per hour!" The alchemist's face was full of surprise.
"It's doubled... It's doubled!" Dennis murmured excitedly as his left fist hit his right palm heavily.
Tim's eyes widened with disbelief, and Linn was also amazed. He originally thought it was too early to build a jet plane, but now Dennis taught him a lesson and told him with practical actions, what? It’s called using magic and alchemy to solve problems!
