The particular construction of any paper aircraft, by Ludwig Prandtl at the 1924 banquet of the International Union of Theoretical and Applied Mechanics, was dismissed as an artless exercise by Theodore von K? rm? and


The most significant use of paper models in airplane designs were by the Wright brothers between 1899 and 1903, the date of the very first powered trip from Kill Devil Hillsides, by the Wright Flyer. The Wrights used a wind tunnel to gain knowledge of the causes which could be used to control an aircraft Origami Instructions Dragon in flight. They built numerous paper models, and tested them within their wind tunnel. By noticing the forces produced by flexing the heavy papers models within the wind flow tunnel, the Wrights determined that control through trip 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 forward to progressively larger models, kites, gliders and in the end on to the powered Hazard (in conjunction with the Bateau Pirate En Papier Maché development of lightweight petrol 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 paper planes as test models for larger aircraft. Within Germany, during the Great Depression, designers at Heinkel and Junkers used paper models in order to establish basic performance and strength forms in important tasks, including the Heinkel 111 and Junkers 88 tactical bomber programmes.


Prandtl was also relatively impulsive. I recall that on one occasion at

an extremely dignified dinner conference using a conference in Delft, Holland, my sister, who sat next to him at the table, questioned him a question 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 plane, not having thought where he was. It landed on the shirtfront of the French Minister of Education, much to the embarrassment of my sister as well as others at the banquet.




There were many design improvements, including velocity, Avion En Papier Simple à Faire lift, propulsion, style and fashion, over subsequent years.


With time, a number of other designers have enhanced and developed the document 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.[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 airline flight performance.



The origin|The foundationgliders is generally considered to be of Ancient China, although there is equivalent evidence that the improvement and development of folded away gliders happened in equivalent measure in Japan. Certainly, manufacture of paper on a widespread scale got place in China five-hundred BCE,

and origami and paper folding became popular in just a century of this period, approximately 460-390 BCE. It is impossible to ascertain where and in what form the first paper aircraft were made, or even the first paper plane's form.




For more than 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 driven flight have all studied paper model aircraft Avion En Papier Simple A Faire in order to create 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. 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 ideas before putting them into practice.
