The most important use of paper models in plane designs were by the Wright brothers between 1899 and 1903, the date of the very first powered flight from Kill Devil Hillsides, by the Wright Hazard. The Wrights used a wind tunnel to gain knowledge of the makes which could be used to control an Bateau En Papier Mode D'emploi plane in flight. They built numerous paper models, and tested them within their wind tunnel. By observing the forces produced by flexing the heavy paper models within the wind tunnel, the Wrights decided that control through flight surfaces by warping would be most effective, and 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, prêt-à-monter, gliders and eventually on to the powered Hazard (in conjunction with the development of Youtube Video Bateau En Papier lightweight gas engines). In this way, the paper model aircraft remains a very important key in the graduating from model to manned heavier-than-air flight.
In 1930 Jack Northrop (co-founder of Lockheed Corporation) used document planes as test models for larger aircraft. Inside Germany, during the Great Depression, designers at Heinkel and Junkers used paper models in order to establish basic performance and strength 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 Origami Easy Animals rather dignified dinner gathering using a conference in Delft, Holland, my sister, who sat next to him or her at the table, questioned him something on the mechanics of flight. He or she started to explain; during it he picked up a paper menu and fashioned a tiny model aircraft, 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 has been many design improvements, including velocity, lift, propulsion, Bateau De Papier Musique 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 earliest known applied (as in compound structures and many other aerodynamic refinements) modern paper plane was in 1909.[citation needed]

In recent years, paper model aircraft have gained great sophistication, and extremely high flight 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 trip performance.
The origin|The foundationairplane diagram is generally considered to be of Ancient China, although there is equivalent evidence that the refinement and development of folded away gliders happened in equivalent measure in Japan. Certainly, manufacture of paper on a widespread scale got place
in China 500 BCE, and origami and paper folding became popular inside a century of this period, approximately 460-390 BCE. It is impossible to ascertain where and in what form the first paper aircraft were constructed, or even the first paper plane's form.
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 ranges. The pioneers of powered flight have all studied paper Origami Box With Lid model aircraft in order to develop larger machines. Da Vinci wrote of the building of the model plane out of parchment, and of testing some 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. Some other pioneers, such as Cl? ment Ader, Prof. Charles Langley, and Alberto Santos-Dumont often tested ideas with paper as well as balsa models to validate (in scale) their hypotheses before putting them into practice.
