About this deal

Paper Planes is a 2015 Australian 3D children's drama film directed by Robert Connolly, which he co-wrote with Steve Worland and co-produced with Liz Kearney and Maggie Miles. The film stars Sam Worthington, David Wenham, Deborah Mailman, and Ed Oxenbould. The film tells a story about Dylan, a young boy who lives in Australia, who finds out that he has a talent for making paper planes and dreams of competing in the World Paper Plane Championships in Japan. [2] As I mentioned above, not all my world record planes can set a record. Most have flight times from 10-14 seconds. Maybe 10% can get to 15-17 seconds, and about 1% can get to 20 seconds. One of the goals of my research and testing is to be able to make the "good" planes on a repeatable basis. The best way I know to do this is to understand the physics involved, and then work on solutions. I have found that the physics involved can get quite complex, and it is difficult to get definite answers from my tests. I do think I am making progress, and hope to continue to improve my understanding and ability to consistently make good planes. Similarly, size, airspeed and mass will have very big impacts on choice of aerofoil, though this is a universal consideration in model plane design, no matter the material.

Steve Worland, who co-wrote Paper Planes, novelised the screenplay into a best-selling book for young readers. It was published on 2 January 2015 through Puffin Books. It includes directions on how to fold a paper plane, photographs from the film, and notes about the production.

In general, there are four aerodynamic forces that act on the paper aircraft while it is in flight: In the case of scale performance and scale models, the modellers intent will define the type of aerofoil section chosen. WWI biplanes, if designed for flight performance, will often have curved-plate aerofoils, as these produce a highly cambered surfaces and Coefficient of Lift (Cl) for low gliding airspeeds. WWII monoplanes will often have very scale-like sections, though with increased trailing edge droop to improve camber in comparison with scale counterparts. Flight performance on bungee is very good - one glider in particular, a scale model U-2 (in the last book of the series) had demonstrated flight performance in excess of 120 meters, on bungee hook launch.

First you fold the paper in half lengthwise, and then unfold. This initial crease is simply a guideline for the next folds. Most full size planes have wings, a tail, and a fuselage (body) that holds the pilot and passengers. Most paper airplanes have just a wing and fold of paper on the bottom that you hold when you throw the plane. There are several reasons for the differences.

More marginal performance and scale types generally do not benefit from heavier, shinier surfaces. Performance profile-fuselage types do experience somewhat improved performance if shiny, slippery paper is used in construction, but although there is a velocity improvement, this is offset very often by a poorer life-to-drag ratio. Scale types have experience negative performance at the addition of heavy shiny papers in their construction. This book was very successful, leading to additional volumes, Paper Pilot 2 (1988), Paper Pilot 3 (1991), 12 Planes for the Paper Pilot (1993) and Ju-52, a stand-alone book featuring a scale model. It is possible to create freestyle versions of paper aircraft, which often exhibit an unusual flight path compared to more traditional paper darts, jets and gliders. Another propulsion technique, creating high launch velocities, involves the use of elastic bands for "catapults". Walkalong gliding involves the continuous propulsion of paper airplane designs (such as the tumblewing, follow foil [12] and paper airplane surfer [13]) by soaring flight on the edge of a sheet of cardboard.

The design of parts of the gliders was achieved using Autodesk AutoCAD R12, then the most advanced version of this CAD software, and one of the first publicly available paper model aeroplanes designed using this technology. There are few technical references for paper airplanes. Naturally paper airplane books talk about paper airplane aerodynamics, but usually in a simplistic manner. There are many reference to low speed flight which are applicable to paper airplanes. Here are a few.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. [ citation needed] It is impossible to ascertain where and in what form the first paper aircraft were constructed, or even the first paper plane's form. Paper models typically have a wing aspect ratio that is very high (model sailplanes) or very low (the classic paper dart), and therefore are in almost all cases flying at velocities far below their wing planform and aerofoil critical Re, where flow would break down from laminar to turbulent.

A number was devised which gives the relative importance of viscosity in fluid flow. It is called the Reynolds Number, and it is the ratio of momentum forces to viscous forces in a fluid. The bigger the number, the less influential the viscosity. The viscosity is essentially a constant for a fluid (it changes a bit with temperature), but momentum is proportional to the speed of a fluid over a surface times the distance it has traveled over the surface. For air it is roughly:
