Now, this is what happened. As soon as Airbus stepped into the industry, within 10 years, the number one airline company in the world, Boeing, stole his touch and hits the US, where everybody knows he has a lot of pain in his ego. Then US did what he did with his opponents, giving back a disproportionate or simply a bigger response. For example, everybody knows that he divided the entire USSSR in the early 90s. But he didn't leave Russia. He joined Russian neighboring countries and formed a new organization by the name of NATO. You can understand historically, US's mindset is the same and how he reacts to any situation. So as soon as US found out that Europe had become number one in the airline industry, he blamed the European governments for unfair support to their Airbus. In the meantime, Europe, in reply to this, put the US on the same allegations. But then they realized that this is a loss for both sides, and they're being too smart to each other's business. And the result? They paused this battle and in 1999, AAPC Agreement, large civil aircraft signed a mutual agreement,Large Civil Aircraft, and set some conditions on each other.


 Conditions like, both governments will give their airliners a fixed subsidy, not more. And in the future, if they have to compete in something else, they will create a level playing field for them. But did they follow that? Well, unfortunately, on the one hand, US was following this agreement with honesty, and on the other hand, our Europe's Fantastic Four were still giving unfair support to Airbus. In short, US was being lied to. But then what was the case? As soon as US found out about this, they filed the case against Europe, straight to the World Trade Organization. They filed the case. And what followed is that WTO, on this whole matter, put their own judge committee and found out that US was right. European governments actually were giving loans to their Airbus, which they had no interest in. Now, after this proof cheating, US took this matter on their nose. They started supporting Boeing and they sent it directly to their Trump card, NASA, to support Boeing. This is how it happened. Nasa, through Boeing's technological expertise and funds combined designed a plane in front of theworld that could give them 30 times the mileage of any other plane in the world, 30 times more mileage, and that too, with the help of simple tricks.

And now coming back to the point, friends, that there were some tricks through whose help NASA and Boeing are going to help Nassau and Boeing increase their American airliners' mileage. So look, those guys are going to be the first is going to keep their plane's design transonic through its braced wings on this concept, which is going to make this plane, compared to today's normal planes, feel a lot less air drag.


Now, if I want, I can shift directly on this concept, but I think before that, I want to give you have to understand some back story. Because normally, the biggest problem in designing any plane is air drag, which often reduces the fuel efficiency of planes and increases the possibility of a crash. Let's understand why. Historically, whenever planes have tried to build, we have always just ignore air drag until the first flying experiments in the year 1891. In those days, when these experiments started, aviators first noticed that when flying, there was a problem and that is air drag. For a long time, no one understood how to reduce it. But then, a solution came from the German aviator, Otter Lillian, who is known today as the flying man. He was the person whose mind, through his mind, he was the person whose contribution, today you are able to fly. Because he didn't give us only gave us the wing concept, but he also gave us something that. on the basisof its efficiency, is still used in modern aerodynamics. I'm talking about drag polar curve, which every airplane manufacturing company uses. Actually, Auto Lilienthal made different wings and experimented on it. 


In these experiments, he noticed that the drag effect of the wings' lift was being affected. They studied this drag in detail and then plotted the complicated drag versus lift graph and gave us the relation between the two. But this was not enough. There was still some shortfall. And that's why, a few years later, an American aviator, Samuel Langley, in his experiment, found that by lengthening the wings, the drag on the wing was reduced significantly. And then, using the funds of both aviators, on 17 December 1903, Wright Brothers made the world's first controlled flight key, and for us, opened the doors for us to air travel forever. But Wright Brothers' plane was a barebone structure, and the air could easily flow through it. But this structure was not right for big passenger jets. Because you may not know, but just after 17 years of Wright Brothers' flight, this Hanley Page plane, literally crashed while takingthat due to its wings being extremely air drag on its wings, it was not able to gain altitude. Actually, those engineers had to believe that a plane's lift should be straight up.


But then with time, we found out that actually, the wings up and the air flowing from below, putting pressure on the tip and bends, which is why the lift is bent backwards instead of being straight. takes place. It means that the components of this lift act not only act on the upper part, but act on the back part as well. And the component acting backwards is what engineers call induced drag. This drag is important to some extent, but if it increases, it can also cause an accident of the planes. Because if the pilot takes the wings faster for more lift, then the induced drag will oppose the wing's lift, and it will cause the plane to crash instead of going up, like what happened with that Hanley Page plane. Interesting, right? Well, this is just half the story. In those days, the plane's wings area of the wing of the planes was increased. That is, when the wind hit them, then because of the friction, it would become a parasitic drag, which affected the speed of the plane. Ingenious had to deal with two drags. Sofirst, to reduce induced drag, they lengthened the wings. This led to the fact that the tips of the long wing to move away compared to the smaller wing. 


This reduced the induced drag in the plane. And to deal with the parasitic drag, they gave the wing's front of the wing a peer shape. Because of this shape, most of the air used to hit its front of the wing and go up, meaning the air used to have very little contact with the wings, which reduced the friction and in turn, the paracetic drag reduced. Simply speaking, friends, the longer and thinner the wings, the lower the drag. And on this basis, the length to width ratio today, we call it aspect ratio. The thing about this aspect ratio is just the fact that every airliner has to keep the length to width ratio of their planes within it for optimum efficiency. Because you see, the lower the drag, the more efficient the plane will be, and commercial airliners can earn more profit. So, according to the recommended aspect ratio, the wings' length to width ratio of wing's length to width should not exceed nine. But guess what? Nasa has designed a design that has an aspect ratio of more than a half. See, this is NASA'swings' length to width ratio of wing's length to width should not exceed nine. But guess what? Nasa has designed a design that has an aspect ratio of more than a half. See, this is NASA's Boeing's plane design, which is based on the transonic truce brazed wing..
