The highest flying paper plane

When it comes to "paper airplanes", people will talk more. It is an indispensable toy for everyone's childhood. A piece of paper can make friends play for a long time, and then hold a lively "paper airplane competition" to see who can fly farthest, so he became today's "origami airplane king".

The hero in today's story is a "hardcore paper airplane enthusiast". He folded a paper airplane for more than 40 years, and even spent 10 years learning physics, fluid mechanics and other knowledge by himself. Just to fold a world-class paper plane, God helps those who help themselves. He finally succeeded. He has folded a paper plane that can fly a full 69 meters, breaking the Guinness World Record. Today, we are here.

His name is john collins john collins, and he is an ordinary American. When he was a child, he was as addicted to origami planes as everyone else. He often won the "paper plane competition", which made John very happy. At this time, no one will know that this child with a paper plane will become a "paper plane master" in the magical world in the future.

On February 26th, 20 12, John, who was over 500 years old, took his favorite paper airplane "Susan" to the Guinness World Records certification site. This time, he wants to break the world record. To this end, he specially invited Joe Ayoob, a rugby player, as the person who "launched" the paper plane. Finally, John's paper plane flew 226 feet 10 inch.

So what's the mystery behind "Susan Paper Plane"? In this regard, John made no secret of it and generously disclosed his own production method. Surprisingly, this "Susan Paper Plane" doesn't use any "secret materials". The raw material is an A4 paper. Then why can it fly so far? Don't worry, let's keep watching.

First of all, we want to know something called Bernoulli's principle. As early as 1726, physicist daniel bernoulli discovered this principle. Simply put, it is "the greater the air velocity, the smaller the pressure; The smaller the flow, the greater the pressure. " Take a real plane as an example. When the plane is moving at high speed, the pressure will gradually increase and the lift will also increase, so the plane will fly.

In the same way, if you want your paper plane to fly as high and as far as a real plane, you must have strong thrust and strong lift, which is why John asked a rugby player to help him "push out the paper plane". Satisfied Bernoulli's principle, let's talk about "gliding ratio".

The so-called gliding ratio is the ratio of gliding distance to initial height without any power, and then the center of gravity, lift center, boundary layer and so on of the paper plane are calculated. After considering these factors, John can fold the plane according to the data, and it should be noted that the angle between the wing and the fuselage must be obtuse, and the folding angle must be clean and tough, and it is best to press it evenly with hard objects.

John also told everyone that these data directly affect the flying height and distance of paper planes. For example, by adjusting the curvature of the wing part, a "rotary plane" that can fly back to the hand can be folded. In order to master these principles, John has taught himself the knowledge of physics and fluid mechanics for 65,438+00 years. Interested friends can watch the video recorded by John, which is very long, so I won't put it here. )

Writing here, Bian Xiao really can't help feeling that origami plane is also a science and an art. Readers, did you ever fold a paper plane when you were a child? Do you think there are really so many scientific principles hidden in the paper plane? Welcome to discuss in the comments section.
