Why Skiiers have a V line

There's a lot of nerves and excitement that you gain in a bit of speed in a short amount of time, and you start to get a feeling of tunnel vision almost. Then when you get into flying, you see the whole mountainside open up. Ski jumps are mainly a sport about using techniques in physics to fly as humanly as possible. Then doing that successfully all comes down to this V line shape. One hundred years ago, Olympic ski jumpers looked a little different. They had a Y position, and the skis were held tightly in parallel—hands in front of their kind of a less posed version of superman. However, by the 1950s, jumpers moved their arms back and to the side. They still kept the same position in the same shape. Everyone did because the goal was ultimately to fly and not do it with style. After all, the further you land from the K point, the more points you get and some style because judges award more points relative to the distance score

for looking cool. People had a straight, elegant line for a long time, with skis tight underneath them.

The parallel position helped athletes cut through the air quickly; it was the standard for decades. A cultural reset too many. That is until the 1980s, another cultural reset happened. The Swedish person named Jon Boklov struggled to keep his skis paralleled but noticed something else on some of his jumps. When you open a ski a little into a broader range to a more extensive V, he achieves longer distances. This breakthrough made sense as this position allows you to catch a lot more air with your body than the straight line parallel ski. You have two key parameters: you are trying to optimize how fast you are moving forward and how fast you are moving down.

Airflow is key to ski jumping because you want to go down as slowly as possible once you are in the air, you want to stay aloft, but you also want to go forwards as fast as you can. The Surface area has much power there. A parallel position has a relatively low surface area; it makes the athlete as thin and small as possible. This is a pretty good aerodynamic shape. Suppose you are trying to maximize your forward speed. You are lining up your body with the skis so the air can go around the ski and the body at the same time in kind of the same little bubble that it forms around you. So that is good for reducing drag; however, the caveat is resisting gravity; it does not do much to prevent you from falling through the air to the ground, in contrast to when the athletes open their skis up into a V formation. They maximize their surface by allowing air to push against their bodies directly.

Instead Of just trying to be like a bullet, you are trying to be a wing. The V line position helps create something called a lift. The lift is a tricky concept. This is an important concept because the basis for it is flight. It is what makes planes fly, and birds fly. The key to this is that air kind of moves over the body. It follows the shape of the body. Then you will see that they are at an angle, and it is imperative to be at an acute angle. If you put your hand out of the window of a car and put it straight, it just pushes straight backward. However, you have to play it a little, but it at one angle. It pushes you up and pushes your hand up and back. What do you guys think? Have you ever gone skiing before?
