Chapter 185 Power Parachute (B)

There is another one, that is, the cutting and sewing of this fabric also has a lot of requirements.This is not sewing clothes, it can be sewn in a few strokes, and it is shameful to open the ends when it is not sealed well.But if the sewing is not good, and there is a problem in the process of using it, it will be fatal.So this also needs to go through various experiments and explorations to verify.

Let's talk about the paracord, this is also very important.It is a bridge between umbrellas and people.If this goes wrong, no matter how strong your umbrella is, it will be useless.The main and most important thing about this paracord is that it is strong.And it's famous for its toughness.In later generations, Jiang Chen was exposed to a lot of outdoor or extreme sports, and the ropes he came into contact with were all parachute and parachute ropes for advertising and marketing.Of course, Jiang Chen praised it again and again after actually touching it. This one is also very strong, and a very thin one can reach a pulling force of seven to eight hundred kilograms. It can be seen that it is not bad.There are two main technical difficulties of the paracord. The first one is the material of the paracord itself. What is it made of, cotton?numb?nylon?It is made of other materials, or different materials are made according to a certain ratio. What is the ratio, and which effect is better? This has to be verified many times.

The second is its weaving process, what method it is used to weave, this also determines the strength of the paracord.A good weaving process has a lot of attention, such as how to deal with the joint problem of the material during the weaving process, how to prevent the wear of the paracord, and how to deal with the damage to the entire paracord due to the breakage of one line during use. The impact of paracord and so on.

In response to these problems, Jiang Chen and the others also contacted domestic manufacturers that specialize in the production of such parachutes.Although Jiang Chen and the others got a bit of technology and craftsmanship from them through a series of relationships and public relations, this is still far from what Jiang Chen and the others requested.Everyone knows that there is still a gap between the craftsmanship of this parachute and the craftsmanship of a paraglider.Most of this parachute is circular and inoperable. It is all driven by airflow, and it will be there wherever it falls, so the force on it during the landing process is still very uniform.But paragliders are different.It uses airflow to control, so the force on the umbrella will be relatively large.This means that a paraglider has to withstand more forces than a parachute, so it has to be made stronger and more reliable than a parachute.

Of course, it doesn't mean that there is no gain. At least Jiang Chen and the others have learned about some crafts and technologies about parachutes, and have some new ideas.And if it is carried out according to this, it will be successfully developed, but it will take a long time and the progress will be slow.But Jiang Chen didn't want to do this, he thought of a new way, entrusted Smith in Laomei to buy them several different paragliders in Europe and Laomei.Since the paraglider was invented, it has quickly become popular among young extreme enthusiasts, so it is not difficult to buy it.Because there is a market, there is a business opportunity, so those businessmen will not give up such an opportunity to make money.

The whole team was excited when they received the paraglider brought over by air transport from Laomei.Although they had heard the name of this paraglider before, they had also seen the design drawing drawn by Jiang Chen.But all the time, they didn’t see the real thing, and now they saw the real thing all of a sudden, and there were multiple ones, which made them ecstatic.And many 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.

After analyzing and researching the technology and technology learned from domestic manufacturers and the paragliders bought from abroad, the R&D team quickly mastered the technology and technology, and finally produced their first pair of paragliders according to their actual needs. Tool.No, this is just the beginning, there is still a lot of work to be done to develop your own paraglider.For example, this wind experiment, and then based on the data obtained from the wind experiment, it has to be modified.Then there is the tension test to see how much tension the entire umbrella surface and paracord can withstand.And this alone is far from enough, and it is necessary to experiment with the direct and sudden change of the pulling force.This conversion is actually to quickly switch different forces and then pull it from multiple angles and under various climatic conditions to test its reliability in different environments and conditions.

Of course, it is not enough to have a good paraglider, the focus is on his power unit.As for this, Jiang Chen actually only read the information on this aspect, and he had no actual contact with it, so he still started from the beginning.The first is the problem of the engine. It uses a motorcycle engine, but there are certain requirements for the engine.For example, the reliability of the engine is still very important for this powered paraglider, and then it is an adaptation to the environment.For example, a powered paraglider is flying in the air. If it is in some special environment, it can continue to work.For example, sudden rain, such as snow, sudden drop in temperature, these may cause the engine to stall.You can stop repairing if you turn off the engine on the ground, but what to do in the air, these are all issues they have to consider.

Then there is the issue of the propeller blades at the back.The design and research of this fan blade involves more professional fields, such as its fluid mechanics and aerodynamics, etc. This is not something Jiang Chen and the others can design and develop, and must be developed by a professional research institute.Many people don't understand, thinking that this is just a reaction force. If you want to make it so troublesome, just install the blades of an electric fan and it will be over.In fact, this is really not the case. The wind from the electric fan is only strong enough to push people into the sky.Therefore, a specially designed fan is required to make full use of this wind force.

After more than a month of continuous public relations research and development, the first powered paraglider was finally produced.Of course, this is not a success, and repeated experiments and field test flights are required.When it comes to this test flight, it must be very dangerous, and they are also quite critical of this factory leader (as the leader of the service company's parent factory and owning the shares of the service company, they have the right to know and participate in this matter), and think that it must Do you want to take this risk, or do you have to develop this?In fact, the leaders of the factory were also acting for Jiang Chen. If there was an accident and people died, it would be very unfavorable to the service company and Jiang Chen who were on the cusp of the storm, and it would affect Jiang Chen's future.Having met such a good seedling, they really didn't want Jiang Chen to suffer a big fall in this matter.

Jiang Chen thought for a long time and then said firmly, "Do it!"
