Of the thousands of things you can do this summer perhaps you hadn't thought about how to improve your technique on paper airplanes. If you want to impress children with your papyroflexia skills don't miss all the steps to build a paper airplane.
Why does a paper airplane fly?
To get a paper airplane to stay in the air for a considerable amount of time, several physical forces must be combined: the thrust, the lift, the air resistance and the weight of the airplane.
In a normal airplane the thrust is carried out on the propellers or turbines, while in a paper airplane it is your own arm that acts as the turbine when you launch it. The air resistance will do the rest to stop the paper plane when it loses strength.
Since a real plane has balanced thrust and drag on the one hand, and weight and lift on the other, it moves in a straight line. In a paper plane the structural weakness makes it impossible to balance these forces and therefore the flight is unpredictable.
If you want to amaze children with the distance the paper plane flies, it will be key to make it robust enough to withstand the lightest blows of the wind. If you want it to be fast, the wings shouldn't be too big.
How to make a paper plane step by step:
There are many versions of paper airplanes, here we are going to keep the so-called stable aircraft, a little more advanced than the basic but very easy to build:
1. Fold a sheet of paper in half.
2. Reopen the sheet of paper and then fold the top two corners toward the center line.
3. Fold the top spout down to make a square.
4. Fold the top two corners toward the center so that the top is the shape of an inverted triangle.
5. Fold up the peak at the bottom to fix the wings.
6. Fold the plane in half.
7. Fold the wings in half on both sides of the paper.
8. And that's it, all that's left to do is fly it!
What is the world record for paper airplanes?
In 2012 Joe Ayoob, a former football player, broke the Guinness record for the flight of a paper airplane, no more and no less than 69 meters away.
And the plane that lasted the longest in the air was the one built by Ken Blackburn in 1998, which made it float in the air for 27.6 seconds.
