The most important use of paper models in plane designs were by the Wright brothers between 1899 and 1903, the day of the first powered flight from Kill Devil Slopes, by the Wright Hazard. The Wrights used a wind tunnel to gain knowledge of the makes which could be used to control an airplane in Origami Star Of David flight. They built numerous paper models, and tested them within their wind tunnel. By watching the forces produced by flexing the heavy document models within the blowing wind tunnel, the Wrights determined that control through airline flight surfaces by warping would be most effective, and in action identical to the later hinged aileron and elevator surfaces used today. Their paper models were very important in the process of moving on to progressively larger models, kites, gliders and eventually on to the powered Flyer (in conjunction with the development of Origami Flower lightweight petrol engines). In this way, the paper model aircraft remains a very important key in the graduation from model to manned heavier-than-air flight.
In 1930 Jack Northrop (co-founder of Lockheed Corporation) used paper planes as test models for larger aircraft. Inside Germany, during the 1930s, designers at Heinkel and Junkers used paper models in order to create basic performance and structural forms in important jobs, like the Heinkel 111 and Junkers 88 tactical bomber programmes.
Prandtl was also fairly impulsive. I recall that on one occasion at a rather dignified
dinner gathering following a conference in Delft, Holland, my sister, who sat next to him or her at the table, asked him something on the mechanics of flight. This individual started to explain; in the course of it he picked upwards a paper menu and fashioned a tiny model airplane, not having thought where he was. It landed on the shirtfront of the France Minister of Education, much to the embarrassment of my sister while others at the banquet.
There have been many design improvements, including velocity, lift up, propulsion, Origami Heart Bookmark style and fashion, over subsequent years.
With time, a great many other designers have enhanced and developed the papers model, while using it as a fundamentally useful tool in aircraft design. One of the original known applied (as in compound structures and many other aerodynamic refinements) modern paper plane was in 1909.

Recently, paper model aircraft have gained great sophistication, and very high trip performance far removed from their origami origins, yet even origami aircraft have gained many new and exciting designs over the years, and gained much in conditions of flight performance.
The origin|The foundationgliders is generally considered to be of Ancient Tiongkok, although there is equal evidence that the improvement and development of folded away gliders took place in the same measure in Japan. Undoubtedly, manufacture of paper on a widespread scale required place in China five-hundred BCE,
Over a thousand years after this, paper aircraft were the dominant man-made heavier-than-air craft whose principles could be readily appreciated, though thanks to their high drag coefficients, not of an exceptional performance when gliding over long distances. The pioneers of run flight have all studied paper model aircraft in order Origami Owl Locket to develop larger machines. Da Vinci wrote of the building of any model plane out of parchment, and of testing a few of his early ornithopter, an aircraft that flies by flapping wings, and parachute designs using paper models. Thereafter, Sir George Cayley explored the performance of paper gliders in the late 19th century. Additional pioneers, such as Craigslist? ment Ader, Prof. Charles Langley, and Alberto Santos-Dumont often tested ideas with paper as well as balsa models to confirm (in scale) their theories before putting them into practice.
