The flight principle of paper airplane;
The material of paper plane is an important factor affecting flight. Paper with rough surface has great friction resistance with air. Too heavy paper needs more buoyancy. Paper planes made of these papers can't fly far. Therefore, the paper plane made of smooth and good texture paper has better flying effect, such as commonly used printing paper or advertising paper.
Different folding methods will also affect the flight distance of paper airplanes. In order to keep the balance of the fuselage, when folding the plane, the wing can be folded up slightly and the tail can be tilted up, so that during the flight, the air will push down the paper plane, so that it can fly more smoothly. At the same time, the larger the wing area of a paper plane, the greater the buoyancy of flying in the air and the longer the flight time.
