What is the flight principle of a paper plane?

The lift principle of paper plane is the lift principle of delta wing, because the plane has power and a certain angle of attack when thrown out. Therefore, there will be circulation on the wing. Under the action of circulation, the fluid velocity on the lower surface of the wing is lower than that on the upper surface, and the pressure on the lower surface of the wing is higher than that on the upper surface.

Factors affecting the flight of paper airplane;

Aircraft structure, paper material, tail arc angle, wing area, aircraft center of gravity, aircraft weight, throwing angle, throwing force.

The structural elements of a paper airplane are: wings, a heavy nose (due to lift, such as the nose is too light to be balanced), moderate overall weight, left and right balance, and a tail or body double.

Making toys out of paper is thought to have originated in Greece 2000 years ago, when "kite" was a popular entertainment. But this is not the same as a paper plane.

The earliest paper plane that can be traced back to the 1980s was made in the west in 1909. However, the most accepted production method was put forward by John K. Northrop (one of the founders of Lockheed) in 1930. Northrop Corporation made a simulation test with paper airplanes to discover the flight mechanism of real airplanes.

Many people claim that they have made "the best paper plane in the world". DC-03 model is one of them (DC-03 paper airplane model). DC-03 has a huge glider and a tail that may be unique among all paper planes. Unfortunately, there is no international paper airplane alliance or association to formally determine whether this is the best airplane in the world. The air time can reach 128 seconds.
