The content of this tea chat has been cut off Vice President Li's solicitation thoughts, archives and organizational relationships, and will never be taken out to talk about things again, from now on, Zhang Yi no longer belongs to the personnel of the General Political School, and of course there will be no papers sent over in the future.

After returning home, Zhang Yi saw Professor Wang waiting for him at home with a person, and immediately greeted: "Hello Professor Sheng, why do you have time to play?" Professor Sheng is also a professor of physics at Yuda University, of course Zhang Yi knows.

Professor Sheng didn't talk nonsense, took a stack of papers and said: "Professor Wang showed me your paper, I want to discuss with you a sail, behind your paper, the design of this kind of sail is much wider than the Mie rule, the front and back and left arcs are also different, and the stabilizer plate and tail fin have also been changed." I noticed that you changed your name to Springboard, and I would like to ask you to explain the reasons for this change. ”

Professor Sheng is an authority on fluid mechanics in China, or an instructor of windsurfing in China, and it is up to him to decide whether windsurfing complies with the Mie rule. Seeing Zhang Yi design this kind of windsurfing, he didn't care about breaking the Michaelis rule, but was very enthusiastic to explore the characteristics of the springboard.

Zhang Yi has great respect for these professors, so he said directly: "After I played Michael's windsurfing last time, I thought it was very fun, and in order to make it more fun and let more people play, I designed this kind of windsurfing, of course, this kind of windsurfing cannot participate in any international competitions." ”

Professor Sheng immediately interrupted Zhang Yi's words: "I know that you can't participate in the competition as a windsurfer, of course, you have employees and members, if you use this internally to compete, no one can control you." I wonder if you're designing this way just to be more stable, suitable for beginners?"

Zhang Yi said with a smile: "Of course, it's not just more stable, that just make it bigger, my springboard is more buoyant, calm the lake, a family of three will not sink if you stand on it, and you can use it as a boat without a sail." Below level 3 winds, it can be more stable in the sea, which is very suitable for beginners, and in level 4 winds, my springboard can jump forward faster than Mie's windsurfing board. ”

Professor Sheng asked: "Your windsurf board is very light, but it is very wide, and you can indeed jump up with the power of the waves and the speed of the wind, but it is probably not easy to jump continuously, right?"

Zhang Yi said with a smile: "It's okay for a normal person to jump four or five times in a row." ”

Professor Sheng said, "Jumping will only be slower, how can you say that you can surpass the speed of Michaelis windsurfing?"

Zhang Yi pointed to himself and said: "I drive this kind of windsurfing board faster than I drive Michael's windsurfing, I am talking about long-distance conditions, which cannot be seen within one or two kilometers." I'm not a competitor in an existing race, but I'm closer to sailing and can sail. ”

Professor Sheng asked: "I don't understand your thinking, if you want to sail, you can just use a sailboat, your board is not like a board, and the ship is not like a ship, is there any point?"

Zhang Yi said with a smile: "It's meaningful, it can let more people play this sport." It is much cheaper than a sailboat, it can be used as a boat in winter, and it can become a sailboat when it is loaded with sails in summer, and it does not take up space at home. The sail is also wider and shorter, the cardan shaft can be limited in angle, and the hand releases the sail and the sail does not fall down. ”

Professor Sheng nodded and said: "You can only be regarded as civilian, so that people who can't play can buy and play, you say fast, and only a very powerful person like you can jump and walk, like a splash, whether it is faster or not, it's hard to say." But does it really make sense?"

Zhang Yi said with a smile: "The shampoo advertisements on TV all use long hair and fluttering, and we all know that the actor's beautiful long hair may not be related to this brand of shampoo." ”

Professor Wang had a lot of contact with Zhang Yi, and he understood it as soon as he heard it, and asked Zhang Yi: "Are you going to jump once to advertise this windsurfing board?" ”

This is marketing, a discipline other than physics, Professor Sheng shook his head and said sharply: "You are grabbing the market and not willing to pay royalties, so you can come up with such a thing." ”

Zhang Yi nodded, and said with a smile: "Why do I have to pay patent fees to make such simple things, can't I make money myself? I will also apply for patents, and others will do this to me, and they have to pay us money." ”

Professor Wang and Professor Sheng looked at Zhang Yi, they could only shake their heads and laugh, they couldn't imagine that Zhang Yi still had the potential of a profiteer, he didn't touch the competition model, developed the civilian model, and named it a springboard, but others couldn't jump up, they could only use normal play, which was to cut a large piece of cake directly from the monopoly.

Zhang Yi said to the two professors: "I asked someone to make it last time, it should be good, let's go to Xiajin tomorrow to give it a try, and by the way, ask the two professors to help me give me some guidance." ”

Professor Wang smiled and said, "It's very fast, it's going to take a look." ”

When the three of them arrived at the Xiajin Shipyard, they saw two signs hanging at the door of a workshop, "Model Aircraft Club" and "Springboard Club", in which at least more than 100 people were installing various model aircraft.

With Qin Feng's strong assistance, after more than a year of accumulation, Xia Jin's model aircraft research team has come up with a lot of ship models, all of which are miniature versions of regular ships. The one-meter-long lifeboat model has all the internal organs, even the lifebuoy, paddle and first aid kit inside are miniature versions, the material structure is exactly the same, and the waterproof skin is the same material as the regular lifeboat skin.

These two people are both professors of Yu University, how do you know that there are these two clubs in the Tianhe Dojo, and at a glance you know that this place is prepared for navigation, Professor Wang took a breath and asked Zhang Yi: "They are all small ships, you are going to develop shipbuilding." No wonder you study windsurfing, you're going to drive the majority of members to the sea first, isn't it?"

Zhang Yi said: "Yes, starting from Xiajin, if there is a small boat, can you play the whole Bohai, go fishing in the sea, it is better than going to the scenic spot to queue up." ”

Professor Sheng had sharp eyes and saw that a person was polishing it, which seemed to be bigger than the springboard on the drawings, so he asked Zhang Yi: "The person over there polished it, it's your springboard, why is it so big?"

Zhang Yi said with a smile: "I only designed one, and when it came to the students, I developed a home version." This family version, the board surface is expanded, like an oval long saucer, 6 meters long, 2.4 meters wide, in the middle is a long box, 2 meters long, 0.8 meters wide, also oval, there is a sealed cover, the sail can be disassembled and placed inside, after the sail is installed, this sealed box, you can put supplies, tired, people can also lie on it, or sleep inside. ”

Professor Sheng looked at Zhang Yi and said, "You are using a windsurfing board for long-distance sailing, and this cover is also equipped with solar panels?"

Zhang Yi said with a smile: "There is a battery in it, which can be used to light and charge mobile phones, and our members are all going to the sea to play, it is not realistic, not only inconvenient, but also unsafe, this can go to the sea, of course, it can go to the river and lake, you can remove the sails, and set up a tent with the mast, as long as it is not a stormy weather, a family of three can play in the river for two days." ”

Professor Wang laughed on the side and said, "Haha, I understand, you are using the name of windsurfing to build a small boat, in order to circumvent the regulations of the ship." After all, shipbuilding, or sailing, is subject to review. ”

Zhang Yi immediately shook his head and said: "This is a windsurfing board for me, and they are all floating on the water, and it is possible to be like a boat." But this is a windsurfing board, which is definitely a piece of sports equipment. ”

These two are connoisseurs, and finally understood that Zhang Yi's windsurfing board was selling dog meat on a sheep's head, and he just wanted to build a small boat, just to get more people into the water, so he made such a strange thing.

Looking at these models in this workshop, they understand that Zhang Yi is to promote navigation, and the sailing board is the first step, which is to lead people into the water, use the sailing board to familiarize themselves with the water conditions, learn the experience of sailing, and after contacting the boat, they can quickly get started, and there must be more things waiting behind to achieve the purpose of allowing more people to sail.

This can be speculated on the surface, but they won't know that Zhang Yi's real purpose is very simple, just to let more people float after the big water comes, this family version of the springboard is what Zhang Yi strives to recommend, being able to jump on the sea is just an additional role, you can jump on the waves, and it will be more stable on the lake.

Even in a violent storm, a person sitting in a long box can not capsize and drown. When the time comes, it will really be used, hold on for three or five days, and you will always be rescued, and you can install sails on it, as long as you can play, you can get to the place you want to go, instead of drifting in the big water, when the wind is not in the right direction, the mast can be used as a penny to support the boat.

After starting to prepare now, in 20 years, Tianhe Dojo will definitely be able to popularize windsurfing boards, like bicycles, to most families.
