The Troublesome Hero Among the Heroes

In the morning of the last two rest days in September, many students from Shield Bridge Academy got up early and came to the side of the Shield River, waiting for the big news.

Unlike in the past, the mystery was revealed on the day of the race. This year's rowing news is constantly changing.

At first, the next door Niudu Academy let out the wind. Their rowing this year is even better than last year.

Followingly, the news that Professor Erbach convened excellent teachers and students to start the development of a new rowing boat spread instantly along with the emergency notice broadcast by the school, but many students were pessimistic about this.

Everyone is a science and engineering course, so naturally you know how difficult it is to design and build a racing boat from the ground up. Maybe the design can catch up, but the time it takes to manufacture is too long.

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

In the next ten days, the steering system was successfully developed after the overthrow, the control system test was completed, the power system linkage debugging was successful, the hull production was completed, and the entire ship assembly was completed. More good news It came one after another at a speed beyond everyone's expectations.

Just yesterday, those students who once again invited the people to shouted told their friends that the new rowing boat will be launched tomorrow!

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

The production of the rowing boats is arranged on the roof of the laboratory building. The space here is large enough. After installing the wooden wall, the girls’ bathroom is no longer visible.

Professor Babbage checked the rope on the shelf. He was called to lift the rowing boat down, but he didn't want to fly halfway and the rope was loose.

If the rowing boat is broken, another one can be built urgently. It would be terrible if it hit someone.

The students on the side are quite nervous, the mutter incantations in the glasses brother’s mouth, listen carefully, it is the calculation of weight and buoyancy.

Charles took his shoulders and said, "Don't worry, it won't sink."

Relying on helping the Academy get two calculators, Charles and his The relationship is good.

Of course, for Brother Glasses, it would be better if Charles called his name instead of "Brother Glasses".

There is also Collins nervously, he is worried about whether the ship will stand up because the rear water jet is too heavy after launching.

Brother glasses have already considered this point, so some counterweights have been added to the bow, so he is afraid that the boat’s buoyancy is insufficient.

Charles is the least worried, because he secretly used teleportation to take the racing boat for a lap at sea last night, and then teleported back.

"That's right!" Charles suddenly remembered something, "Who will sail next?"

A group of students looked left and right, big eyes staring at small eyes During this period of time, everyone is dedicated to shipbuilding, and the pilot has not considered it.

He asked again: "Where was the driver last year?"

"Graduated." Some students answered.

At this time, Professor Babbage had changed back to the giant dragon form, and began to grasp the rope to carry the ship to the shield river to fly.

Then everyone looked towards Charles together. During this period of time, he was coordinating the development of the rowing boat. On the other hand, he could make ideas for any team that encountered problems, and he had already gained some prestige.

Charles thought for a while, he looked towards the most conspicuous person in the crowd, and said, "Leo, let’s drive."

"Huh?" The round Senior Sister was amazed. She never thought that she would be a driver.

Charles said solemnly: "The control system of this rowing boat is designed and manufactured by you. You can feel it yourself, you can get first-hand information and see where you need to optimize it."

Leo thought for a while and said, "You make sense. There hasn't been a boat controlled by a magic brain before. I will try it first."

The other students have no objection. They have seen a purely mechanically controlled boat, but this racing boat sends signals to the core of the magic brain through the steering wheel, push rods and the like, and then controls the power of the propeller and the steering system. No one has the bottom.

Charles sighed in relief. There is a problem with this racing boat. The bow floats when traveling at high speed, and no weight is held down. Maybe it will fly a few times at extreme speeds.

At this time, the glasses brother helped the glasses and said: "If Leo is driving, then the weight of the bow can be reduced."

Charles is speechless, this buddy is too Honestly, then immediately flashed away.

Because the two hundred catties senior Sister suddenly rushed over, she grabbed the glasses brother’s collar and roared: "You [Southern Rogue] laugh at the weight of this Princess, believing or not me right away Let Royal Father propose marriage to your country and let you marry me!"

Brother Glasses admitted on the spot.

Charles inquired, Yuan Senior Sister Leo is the Princess of genuine, and the glasses brother is a neighboring country, and the relationship is very poor.

By the way, some of the bad relations between these small countries are not because they cannot be reconciled, but because they can’t find a step down, and everyone is reluctant to take a step back for the sake of face. If the two royal families are married, the so-called contradiction will disappear.

And the glasses brother has already been a fiancee of childhood sweethearts. She is the second daughter of the domestic military leader Noble. She studied painting at the Art Academy on the island. When everyone worked overtime on the last rest day, she came over for everyone. Send snacks.

The driver’s matter was resolved, and everyone started to go downstairs to the river in a noisy manner to start a trial voyage.

Professor Babbage arrived first. He put the rack on which the rowing boat was fixed on the lawn by the river, and the onlookers were pointing fingers to the rowing boat covered with linen.

Charles and they came, a few people opened the linen, and then a group of people were dazzled by the silver light gleaming rowing boat.

This group of students know that the rowing boat will be sold in the future. Everyone divides the money. There are endless ideas for increasing the price of the rowing boat, including mixing the silver light agent into the slime hard rubber board. It also became.

Leo climbed onto the rowing boat and started the final test before launching.

The onlookers are still watching this rowing boat carefully. It is nearly 20 meters long and its tail section is about 4 meters wide. The side looks no different from the previous magic array power rowing boat, but from the back You can see the difference by looking at it.

It has a row of six square holes side by side at the stern, and each hole corresponds to a water jet. If Charles hadn't stopped them, these guys who believed that great efforts would work miracles were going to put on another row.

As Leo in the driver's seat manipulated the steering wheel, these nozzles began to swing from side to side.

The power system is probably a "◢▀ᴰ" structure, with a water inlet pipe in the front, a three-layer water jet in the middle, and a tail section as a steering device.

At first, the steering device was intended to rotate the pipe connected to the spout to change the direction of the water flow. As a result, the space occupied by the pipe was too large and increased the weight of the rear. The boat stands up.

So Charles simply suggested that a binary vector nozzle similar to F22 be connected to the tail section of the sprinkler tube, so that the baffles on both sides of the spout can be directly rotated left and right, which solves the overweight stern of the ship. problem.

Some onlookers looked at the bottom of the ship and found a long row of holes there.

These water inlets on the bottom of the ship are designed by Charles. The long oval opening area is much larger than the cross-sectional area of ​​the spray canister, which can provide enough water to the spray canister to avoid "idling" due to insufficient water intake.

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

The commissioning of the system was completed and all parts responded well, so everyone carried the rowing boat into the water together.

Leo, who returned to the driver's seat, adjusted the tightness of the life jacket on his body, tested that there was no problem with the intercom, and then turned on the power system switch.

Then she pushed the power putter of her left hand slightly, and as a stream of water spouted from the stern, the rowing boat slowly moved forward at a walking speed.

Then turned the steering wheel slightly, and everyone saw that the water flow at the stern was all to one side, and the rowing boat began to make a turn towards the center of the Shield River.

Students who participated in the development of the boat cheered suddenly, some students even hugged each other, the boat finally succeeded in getting out of the 1st Step, and then it was time to vigorously work out a miracle.

It’s just that although this section of the river is relatively straight, it is not very long. It will fly to the shore when driving at extreme speed. Tomorrow is the time to test at full speed at sea.

In the following time, Leo sometimes went straight and turned sometimes on the river at a faster speed, testing the maneuverability of the rowing boat.

She is most worried about the simultaneous output of the propellers. Because they are made by hand, the efficiency of these six propellers is slightly different. There will be a slight difference in thrust when the same magic power is input. Time will cause the course to deflect.

In the end, Charles took everyone to test the data of the propellers one by one, and got the relevant formulas, and then distributed the magic power through the control system so that the thrust difference of the propellers was controlled within an acceptable range.

Charles suddenly noticed that Principal was not far away, with a relieved smile on his face.

He walked over to greet Principal, and Principal said: "You arrange the next thing, let other people take charge, and take a walk with me."

Charles Go back and let Vichy preside over the next work, and then leave the river with Principal.

Along the way, he was talking about the internal situation of the development team during this period. The Principal was only slightly nodded and did not make any comments.

One old and one young walked around like this, and finally came to the luxurious box on the top floor of the Aixifan restaurant.
