High-speed ships such as planing boats, wave-piercing boats, hydrofoils, etc., have only seen a picture for Charles, and if he wants to get one of them out in a month's time, it is better to find Professor Babbage to change back into dragon form and drag the rowboat with a rope on his tail.

Ru had no doubt that if he dared to do so, the dragons would dare to throw him off the stratosphere.

After some inquiry, Charles finally understood the requirements of the rowing.

There are only three requirements, the first is that the boat must be powered by magic, the second is that the boat must be less than 20 meters long, and the third is that the boat is forbidden to leave the water for a long time and then disappear.

While everyone waited, Charles spent half an hour on the blackboard to revise and finalize the general design of the racing boat.

The shape of the racing boat is no different from the previous flat-tailed willow leaf shape, and he doesn't have the ability to make a hydrofoil or the like in a short period of time, so let's use a mature design.

The core part is the aft power compartment, and he initially wanted to use an external waterjet propulsion, but he was worried that the resistance in the water would be too high and the thruster would be washed away, so he finally chose a safe solution.

However, he was still a bit aggressive, and the boat opted for a modular power plant, and it was possible to see how many water jets could be built, and if there were more, he would decorate more.

The size of the water jet as the core was set at 80 centimeters long and about 50 centimeters in diameter, which he obtained by referring to a high-power water pump from the Rurika Engine Design Bureau.

"Vichy. Charles pointed to the power module sprinkler part drawn on the blackboard and began to arrange the task, "You are responsible for taking a few people to study my hair dryer and the three-layer wind turbine that was once installed on wheels, and make sure to come up with a feasible water spray design within five days." ”

"The problems of personnel and materials can be solved by the president, and the technical problems can be studied by the professor, and I will also help when necessary. ”

"Can you do it?"

He spoke in a very serious tone at the end, like an officer on the spot. In fact, this is what he learned from Elizabeth.

Weizi said equally seriously: "If you can do it, I can't do it at your disposal." ”

Charles glanced at the apprentice a little speechlessly, and now the crowd of onlookers, from the students to the principal, was gossipy.

But it didn't bother him, "Then you wrote all my homework for me." ”

Professor Kilby, who gave him a lesson, almost choked on the tea.

Charles said, "Who is good at the study of magical active substances?"

A skinny boy raised his hand and said, "This is what our research group is good at." ”

Charles pointed to the power module outlet on the blackboard and said, "Can you use the magic active substance to control the direction of the water flow at the vent, and the rowing boat will rely on it to turn." ”

Armed with a mana active substance that transforms when magic passes, he intends to use the vector spout directly to eliminate the drag caused by the rudder.

The boy pinched his chin and looked down for a few minutes, then went to the blackboard and drew a sketch in the empty space, attaching the action barrel and connecting rod to the hull on both sides of the tube behind the spout.

But he said: "It's easy to turn the spout, but the waterproofing of the turn has to be solved." ”

Charles nodded, this design is simple and practical, that is, the outlet pipe has to be lengthened, and the hydraulic loss in the pipe is a little larger, but it doesn't matter, let's optimize it later.

He said: "Waterproof can be studied later, you should study it carefully, shorten the length of the rotating pipe section as much as possible, and the width of the device on each side should be controlled at about 5 cm, and the maximum should not exceed 10 cm." ”

"5 centimeters?" the thin boy frowned, "if we can only give this little space, we can try the overall steering structure, with the transmissions on both sides controlling a discharge of water pipes at the same time." ”

Charles waved his hand and said: "You are responsible for this system, try to use your imagination as much as possible, come up with a design plan as soon as possible, and find the principal and professors if you have any needs." ”

He also tried his best in this regard, he didn't understand too advanced knowledge, he could only give full play to the wisdom of the broad masses of the people, and the local method was also a way, so he couldn't honestly install the rudder if he couldn't do it, and he couldn't rush to Pearl Village with one foot on the accelerator.

Then Charles said, "Who has research on the core of the demon brain?"

At present, Diana has the highest level of research on the core of the demon brain in the Knowledge City, but Charles has no way to find help from people from other schools, so he can only look at his classmates in this school.

Fortunately, when Diana came to help develop a fully automatic bun machine, she brought out a few people, and at this time it was a round senior sister who raised her hand.

Senior Sister Yuan said: "I have some research on this, and I have participated in the automatic steamed bun machine, dough mixing machine, and large steaming cabinet. ”

Charles said: "The design and production of the control system of the power module and the steering module are up to you, and you can also design the energy system, your task is very heavy, otherwise our racing boat can only run in a straight line." ”

"Hiss......" Senior Sister Yuan gasped, "It's troublesome, I have to ask my friends for help." ”

Charles said: "Just look for it, and the principal will help you solve it." ”

He continued: "Who is good at the design of hull structures?"

This time it was Brother Glasses who raised his hand, and he said, "I am responsible for the structure of the ship. ”

Charles said: "This time the speedboat is extremely powerful, and it looks like a metal keel is going to be used. ”

"I think so. The glasses brother pushed his glasses, "I plan to use steel pipes to make the keel, which can reduce the weight while maintaining strength." ”

"But what are you going to do with the materials for the hull? ”

"The hull design is up to you. Then Charles looked at Langsha and said, "The hull material is solved by Langsha, and so is the waterproof material for the turn head just mentioned." ”

"Langsha, I'll go back to the lab with you later, I have some ideas to discuss with you. ”

Lang Sha let out an "um", she knew that she only had a little slime material to get her hands on now.

The work was basically arranged, and seeing that everyone had no objections, this made Charles breathe a sigh of relief, and he was afraid that a pig teammate would suddenly jump out and drag him back.

It turns out that there is a principal on the sidelines, and no one is making trouble.

However, this is not a long-term solution, and the stress of everyone will quickly accumulate during the next month of high-intensity work, and then a little spark will detonate.

So Charles looked at Professor Erbach and said, "Headmaster, I have two areas where I need help. ”

Professor Elbach was very satisfied with Charles's performance just now, it is not easy for a young man to set the main direction and arrange the parts separately, instead of rushing up with people and no one knowing what to do. This requires a comprehensive understanding of the job, as well as extensive experience in organizational leadership.

The old principal attributed his performance to Elizabeth's training, but he did not expect that this was the basic operation of construction management on the construction site, and the carpentry, rebar worker, scaffolding worker and concrete worker performed their own duties, so that a building could be built in an orderly manner.

In Charles's eyes, the few classmates he called just now are equivalent to the team leaders of various types of work, and if there is anything, you can communicate with them directly, and the internal affairs of their group will not be taken care of, which can save a lot of time and energy.

At this point, Professor Elbach said, "Is there anything else I need to solve?"

Charles replied: "First of all, I recommend that the teams try to be concentrated on this floor as much as possible, so that we can communicate immediately when we have a problem. ”

Professor Erbach nodded and said, "Yes, I agree, let's gather the people who need it later." ”

Charles added: "In order to save time for eating, I suggested finding a room on this floor to be used as a canteen, and our daily meals were provided free of charge from the third floor of the canteen. ”

The principal twitched, the third floor of the cafeteria provided high-quality dishes, and the price was not cheap.

Charles continued: "As long as the third floor of the canteen provides three meals a day, afternoon tea and supper, I think everyone will be very motivated. ”

The headmaster's face began to cramp, which cost a lot of money.

However, he quickly understood that this was Charles's sweetness for everyone, after all, the students who could eat on the third floor of the cafeteria were a minority, and they could eat for a month, so what was it if they were busy while working.

Compared to the magic materials, the cost of the students' food for this month is ...... It doesn't seem to be low.

However, the principal is always the principal, and in order not to lose three in a row, he gritted his teeth and agreed.
