Fractal Fins Wingtips

Many moons ago, I was watching a YouTube video about new Gulfstream winglets that a subcontractor was making for the company. The same company also manufactures winglets for Airbus, Boeing and around 60 types of aircraft. I was totally amazed by the progress of this company since 1991 when it was founded. These latest winglets they offer are completely molded, and you can’t tell where the wings end and the winglets start, as it looks like it’s all in one piece, therefore it is.

That obviously makes sense because the airflow coming out of the winning wingtip vortices doesn’t start and stop, as it’s also a continuous flow. Maybe that’s why I immediately thought there should be fractal fin wingtips. That is to say that at the tip of the fin there must be some fins, and another one at the tip of that one, and so on, and why not? Interestingly, while reading the comments below the YouTube video, I noticed that someone else had made the same statement.

I actually know aerospace engineers have to be thinking here, but I’m asking why haven’t those designs been created yet, or if the military is already using them, they could work very well on rotor blades for high speed helicopters, or how about hypersonic transition ship? Some might say the reason is because there is the law of diminishing returns, and that may be true, but that law of diminishing returns is still a return on efficiency, so it’s worth discussing.

Also, how hard is it to put a fin on the tip of the fin, with a fin on the tip? As long as it’s just molded plastic or carbon composite, there’s no problem continuing with the mold. Not that the manufacturing process for such materials is that difficult.

Meanwhile, there are many things that stick out of an airplane. There are antennas, vertical stabilizers, horizontal stabilizers and all sorts of other things, shouldn’t they all have lots of ailerons to increase efficiency and reduce drag coefficient? All that parasite drag could be cut down a bit.

Maybe we should be thinking here, especially since at the Paris Air Show in 2011, it was all about fuel costs and saving money. Gulfstream and Boeing flew planes on BioFuel to the Paris air show, and companies similar to the one that makes this winglet were also there selling their products, to an excited crowd of plane buyers who are very interested in green aviation and efficiency. to save fuel. costs

Yes, it’s nice to build more efficient new planes, but let’s make some of the older planes we have efficient too. And it’s not like we can’t improve even on the new efficient plane with molded fractal fins and lighter weight materials. Why not make all planes as green as possible? In fact, I hope you will please consider all of this and think about it.
