The origin of folded paper gliders is generally considered to be of Ancient China, although there is equal evidence that the refinement and development of folded gliders took place in equal measure in Japan. Certainly, manufacture of paper on a widespread scale took place in China 500 BCE, and origami and paper folding became popular within a century of this period, approximately 460-390 BCE. For 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 powered flight have all studied paper model aircraft in order to design larger machines. The most significant use of paper models in aircraft designs were by the Wright brothers between 1899 and 1903, the date of the first powered flight from Kill Devil Hills, by the Wright Flyer. The Wrights used a wind tunnel to gain knowledge of the forces which could be used to control an aircraft in flight. With time, many other designers have improved and developed the paper model, while using it as a fundamentally useful tool in aircraft design. I recall that on one occasion at a rather dignified dinner meeting following a conference in Delft, Holland, my sister, who sat next to him at the table, asked him a question on the mechanics of flight.
In recent times, paper model aircraft have gained great sophistication, and very 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 terms of flight performance. There have been many design improvements, including velocity, lift, propulsion, style and fashion, over subsequent years. Widespread manufacture, and inexpensive nature of acetal air-annealed glues, e. Unmodified origami paper aircraft have very poor glide ratios, often not better than 7. 5:1 depending on construction and materials. Previously, paper model aircraft had been designed without an emphasis on performance in flight.
By using aerodynamic design, and fluid dynamics, both professors were able to design models that exceeded previous flight performance criteria by a very wide margin. At present, the work of the two professors remains the last serious research work on improving the flight performance of paper model gliders. Collaborative work by enthusiasts through online forums and personal websites are mostly developments of these original glider types. In the field of scale model design, there are at present many possibilities for advanced design. Profile gliders encounter a limitation for improvement of flight performance based on their wing types, which are typically curved-plate aerofoils.
