On the morning of the last two rest days in September, many students of Dunqiao Academy got up early and came to the side of the Dunhe River, waiting for the arrival of big news.

Unlike in the past, when the mystery was revealed on the day of the race, this year's rowing news continued.

At the beginning, the next door Niudu College let out the wind, and their rowing this year was even better than last year.

Immediately afterwards, the news that Professor Erbach had summoned outstanding teachers and students to start working on the new racing boat anew spread with an urgent notice on the school radio, but many students were pessimistic.

As a science and engineering student, we all know how difficult it is to design and build a racing boat from scratch. Maybe the design is in time, but the manufacturing time is too long.

Just a few days later, the good news suddenly came, the students involved in the development of the rowing suddenly invited their friends to dinner to celebrate the first victory of the rowing power system.

In the next ten days, more good news such as the successful development of the steering system after overturning and restarting, the completion of the control system test, the successful commissioning of the power system linkage, the completion of the hull production and the completion of the assembly of the whole ship came one after another at an unexpected speed.

Just yesterday, the students who had once again invited themselves to a great meal told their friends that the new rowing boat would be launched tomorrow for sea trials!

After listening to the news for so many days, everyone can finally see the real thing.

The rowing was made on the roof of the laboratory building, which was large enough to have a wooden wall and no longer see the girls' bathroom.

Professor Babbage checked the ropes on the rack, and he was called to lift the boat down, but he didn't want the rope to break halfway through.

If the boat is broken, you can urgently build another one, and if it hits someone, it will be miserable.

The students on the side were quite nervous, and the glasses brother had words in his mouth, and when he listened carefully, he was checking the weight and buoyancy.

Charles put his arm around his shoulders and said, "Don't worry, it won't sink." ”

Thanks to the help of the academy to get two calculators, Charles had a good relationship with him.

Of course, it would have been better for Charles to call himself by his first name instead of "Brother Glasses".

Equally nervous was Collins, who was worried about whether the ship would stand up after launching because the waterjets in the rear were too heavy.

Brother Glasses had already considered this, so he added some counterweights to the bow of the boat, so he was afraid that the buoyancy of the boat would not be enough.

Charles was the least worried, because he secretly used teleportation to take the boat around the sea in the middle of the night, and then teleported back.

"That's right!" Charles suddenly remembered something, "Who's going to open the boat?"

A group of students looked left and right, staring at each other, everyone was concentrating on building a ship during this time, and the driver had not considered it.

He asked, "What about last year's driver?"

"Graduated. A student replied.

By this time, Professor Babbage had reverted back to his dragon form, and began to grab the rope and carry the boat towards the shield river.

Then everyone looked at Charles together, during this time he was coordinating the development of the rowing on the one hand, and on the other hand, he could come up with ideas for any group that encountered problems, and his prestige had already been reached.

Charles thought for a moment, he looked at the most conspicuous person in the crowd, and said, "Leo, you can drive." ”

"Huh?" the round-looking senior sister was very surprised, she never thought that she would be a driver.

Charles said seriously: "The control system of this racing boat is designed and built by you, you can feel it for yourself, you can get first-hand information and see what needs to be optimized." ”

Leo thought for a moment and said, "You have a point, there really hasn't been a ship controlled by a demon brain before, so I'll try it first." ”

The other students had no objection, they had seen a boat controlled by pure machinery, but this racing boat sent signals to the core of the magic brain through the steering wheel, push rod and the like, and then controlled the power of the thruster and the steering system, and no one had a bottom.

Charles breathed a sigh of relief, there was a problem with this racing boat, that is, the bow would float at high speed, and there would be no weight to hold it down, and maybe it would fly up and spin a few times at top speed.

At this time, the glasses brother helped his glasses and said, "If Leo is to drive, then the counterweight on the bow of the boat can be reduced." ”

Charles was speechless, this guy was too honest, and immediately flashed away.

Because the two-hundred-pound Senior Sister Yuan suddenly rushed over, she grabbed Brother Glasses by the collar and roared angrily: "You [Southern Foul Mouth] laugh at the weight of this princess again, believe it or not, I will immediately ask my father to propose to your country and let you marry me!"

Brother Glasses confessed on the spot.

Charles inquired on the side, Senior Sister Leo is a real princess, and Brother Glasses is a neighbor, and they have a very bad relationship.

Having said that, some of the bad relations between such small countries are not irreconcilable contradictions, but they cannot find the bottom of the stairs, and everyone is reluctant to take a step back for the sake of face. If the royal families of the two countries marry, this so-called contradiction will disappear.

And Brother Glasses has long had a fiancée of his childhood sweetheart.,It's the second daughter of a domestic military noble.,Learn painting at the art academy on the island.,Last day off, when everyone worked overtime, she also came to give everyone snacks.。

The driver's matter was solved, and everyone began to go downstairs to the river in a noisy manner to start the sea trial.

Professor Babbage arrived first, placing the rack holding the rowing boat on the riverside lawn, and the crowd of onlookers pointed at the linen-covered rowing.

Charles and the others came, and a few of them lifted the linen, and then a group of people were dazzled by the silver glittering rowing boat.

After the students learned that the boat would be sold and everyone would share the money, there were endless ideas to increase the price of the boat, including mixing silver light into the slime hard plate, and it actually happened.

Leo climbed into the boat and began to do the final tests before entering the water.

The onlookers were still carefully observing this racing boat, it was nearly 20 meters long, the tail was about 4 meters wide, and the side looked no different from the previous magic array power racing boat, but it could be seen from the back.

At the stern of the ship there is a row of six square openings, each corresponding to a waterjet. If it weren't for Charles, these guys who believe in miracles would have planned to install another row.

As Leo in the driver's seat operated the steering wheel, the spouts began to swing from side to side.

The power system is probably "◢????" structure, with a water intake pipe in front, a three-layer water jet in the middle, and a steering device in the tail.

In the beginning, the steering gear was intended to turn the tube that connected the spout to change the direction of the water, but the result was that the tube took up too much space and added weight to the rear, which would make the boat stand up.

So Charles simply suggested that the tail of the nozzle should be connected to the kind of binary vector nozzle similar to the F22, so that the baffles on both sides of the nozzle could directly rotate left and right, which solved the problem of overweight in the stern.

Some onlookers looked at the bottom of the boat and found that there was a long row of holes.

These bottom inlets were designed by Charles and have a long oval opening area much larger than the cross-sectional area of the sprinkler to provide enough water to the sprinkler to avoid "idling" due to insufficient water intake.

Since the direction of the water inlet is perpendicular to the horizontal plane and the water nozzle is parallel to the horizontal plane, Charles designed this section of the pipe into a rounded arc to reduce water loss.

The system was debugged and all parts responded well, so everyone carried the racing boat into the water.

Leo, who returned to the driver's seat, adjusted the tightness of the life jacket on his body, tested the walkie-talkie without problems, and turned on the switch of the power system.

Then she gave a slight push to the power lever in her left hand, and as a stream of water erupted from the stern, the boat slowly moved forward at walking speed.

Then the steering wheel was slightly turned, and everyone saw that the water at the stern of the boat was all deflected to one side, and the rowing boat began to turn around and move towards the center of the Dun River.

The students involved in the development of the rowing immediately cheered, and some students even hugged each other, and the rowing finally succeeded in taking the first step, and then it was time to make a miracle.

It's just that although this section of the river is relatively straight, it is not very long, and it will fly ashore when driving at top speed, and tomorrow is the time to go to the sea for a full-speed test.

For the rest of the day, Leo went straight and sometimes turned at a faster pace on the river, testing the boat's maneuverability.

Her biggest concern was the simultaneous output of the thrusters, because they were made by hand, and the efficiency of these six thrusters was slightly different, and there would be a slight thrust difference when inputting the same mana, which would cause the course to deflect when sailing.

In the end, Charles took everyone to test the data of the thrusters one by one, came up with the relevant formulas, and then distributed the magic force through the control system to control the thrust difference of the thrusters within an acceptable range.

Charles suddenly found that the principal was not far away, with a relieved smile on his face.

He walked over and greeted the principal, who said, "You arrange the rest of the matter, let the others take care of it, and take a walk with me." ”

Charles immediately went back to let Vichy preside over the rest of the work, and then followed the headmaster out of the river.

Along the way, he was talking about the situation inside the research team during this time, and the headmaster just nodded slightly, without making any comments.

The old and the young just talked and walked around, and finally came to the luxurious box on the top floor of the Aixi Restaurant.
