There is another one, that is, there are many requirements for the cutting and sewing of this fabric. This is not a sewing garment, it will be sewn in a few clicks, and it will be a shame to have a slit when it is not sealed and worn. But if this sewing is not good, and there is a problem in the process of using it, it will be a loss of life. Therefore, this must also be verified by experiments and exploration in all aspects.

Speaking of the paracord, this is also very important. It is a bridge between the umbrella and the person. If something goes wrong with this, then no matter how strong your umbrella is, it's useless. The main and most important thing about this line is that it is strong. And this sturdiness is also famous. In later generations, Jiang Chen was exposed to many outdoor or extreme sports, and the ropes he came into contact with were all used for advertising and marketing with parachute ropes. Of course, Jiang Chen has actually come into contact with it and praised it again and again, this one is also very strong, a very thin one can reach seven or eight hundred kilograms of tensile force, which shows that it is not bad. There are two main technical difficulties of this paracord, the first is the material of the paracord itself, what is it made of, cotton, linen, nylon, or other materials, or different materials are made according to a certain proportion, what is this ratio, and then the effect is better, this has to be verified many times.

The second is its weaving process, what method it is used to weave, and this is also a strong problem that determines the paracord. A good weaving process has a lot of particulars, such as how to deal with the joint problem of the material in the weaving process, how to prevent the wear and tear of the paracord, how to deal with the impact of the paracord on the whole paracord due to the break of a line in the process of use, etc.

In response to these problems, in fact, Jiang Chen also contacted domestic manufacturers specializing in the production of such parachutes. Although Jiang Chen and the others have gone through a series of relationships and public relations to get some technology and craftsmanship in this area from them, this is still far from what Jiang Chen and they requested. Everyone knows that there is still a gap between the craft of this parachute and the craft of paragliding. This parachute is mostly round and non-operable, and is propelled entirely by air currents. Wherever he descended, it was there, so the force on it was still very uniform during the re-landing. Paragliding can be different. It is controlled by air currents, so the force on the wing will be relatively large. This means that a paraglider has to withstand more force than a parachute, so it has to be stronger and more reliable than a parachute.

Of course, it's not that there is no gain. At least Jiang Chen and the others have learned some of the processes and techniques about parachutes, and they already have some new ideas. And if it is carried out according to this, it will be successfully developed, but the progress is relatively slow for a long time. However, Jiang Chen didn't want to do this, he thought of a new way, and entrusted Smith in Lao Mei to buy them a few different paragliders in Europe and Lao Mei. Since the invention of paragliding, it has quickly become popular among some young extreme enthusiasts, so it is not difficult to buy it. Because there is a market, I think there is a business opportunity. So those businessmen will not give up such an opportunity to make money.

After receiving the paraglider from Lao Mei through air transport, the whole team was excited. Although they had heard the name of this paraglider before, they had also seen the design drawings drawn by Jiang Chen. But it's always been.,I haven't seen the real thing.,Now I see the real thing all at once.,And it's multiple.,This makes them ecstatic.。 And a lot of the parts and designs that they didn't understand before are now understood. Of course, they can't just use this, they have to imitate this person to design and develop their own products.

Analyze and study the technology and process learned from domestic manufacturers and the paragliders they buy from abroad. The R&D team quickly mastered the process and technology, and then finally made their first paraglider gear according to their actual needs. No, this is just the beginning. There's still a lot of work to be done to develop your own paraglider. For example, this air outlet experiment, and then according to the data obtained from the air outlet experiment, it has to be modified. Then there is the tensile experiment to see how much tension the entire surface and lines can withstand. And this alone is not enough, but also to experiment with the direct and sudden conversion of this pulling force. This conversion is actually to quickly switch different forces and then pull them at multiple angles and under various climatic conditions to test his reliability in different environments and conditions.

Of course, a good paraglider is not enough. Again, the focus is on his power plant. In fact, Jiang Chen had only read the information about this, and he had not actually come into contact with it, so he still started from scratch. First of all, the problem of the engine, it is a motorcycle engine, but there are certain requirements for the engine. For example, the reliability of this engine. For this power paragliding is still very important, and then a kind of adaptation to the environment. For example, if a powered paraglider is flying in the air, it is a question of whether it can continue to work if it is in some special environment. For example, sudden rain, for example, snow, sudden cooling, these can cause the engine to stall. If the fire is turned off on the ground, they can stop repairing, but what to do in the air are all questions they have to consider.

And then there's the problem of this rear propeller fan blade. The design and research of this fan blade should involve more professional fields, such as its fluid mechanics and aerodynamics, etc., which is not something that Jiang Chen can design and develop, and must be developed by a professional research institute. Many people don't understand, thinking that this is not a reaction force, if you want to make it so troublesome, just install the fan blades of an electric fan. In fact, this is really not the case, how strong the wind of the electric fan is, it is simply not enough to push people into the sky. Therefore, it is necessary to design a specially designed fan to make full use of this wind power.

After more than a month of continuous public relations research and development, the first pair of power paragliders was finally produced. Of course, this is not a success, and it will take many repeated experiments and field test flights. Speaking of this test flight, it must be very dangerous, and there are also quite a few criticisms about the leaders of this factory (who, as the leaders of the parent factory of the service company and the shares of the service company, have the right to know and participate in this matter), think that they have to take this risk, or do they have to develop this? In fact, the factory leaders are also looking for Jiang Chen, if there is an accident and there is a human life, this is very unfavorable to the service company and Jiang Chen on the cusp, and it will affect Jiang Chen's future. encountered such a good seedling, they really didn't want Jiang Chen to plant a big heel in this matter.

Jiang Chen thought for a long time and then said resolutely: "!" (to be continued......)
