Also a teachers guide for this book is available from the publisher with more paper airplane information] By comparison the wings of a four passenger airplane have a Reynolds Numbers of up to about 6,000,000. Also, remember the transition from laminar to turbulent? That happens at a Reynolds number of no less than about 10,000, so the first ½ to ¼ of the flow over a paper airplane's wing is laminar. Since the Reynolds Number is much less than for full sized airplanes, this means viscosity is much more dominant, resulting in more drag, and more difficulty in creating lift.

I’m not sure he had a clear favourite of all the planes in the book. I think the one I like best was the Carnard plane – more because I’ve never folded one with carnard wings before! If you’re not sure what carnard wings are, they are small extra wings on an aircraft in front of the main wings. Thanks to Stef for the explanation – I didn’t know.

This wasn't going to be easy. If successful, it would be my forth time at setting the record. Each time was the absolute I could achieve, with improvements resulting from improving my planes and from working on a faster throw. My best unofficial time, 20.88 seconds, was the product of months of working out and well over 100 airplanes constructed. And I have another enemy sneaking up on me as well - time. I am 35 years old, and soon I know my arm speed is likely to decrease. Its important to realize the basics of why paper airplanes fly, and why full size airplanes fly, are identical. They create lift and drag, and are stable or unstable for the same reasons. However paper airplanes look different than most airplanes. The reason they generally look different is for very practical reasons, but not necessarily due to aerodynamics. There are also some definite aerodynamic differences between paper airplanes and full size planes. These difference are not so apparent, but do affect how paper airplanes fly. Stability means the plane, if disturbed, will return to its original state. For pitch stability it means the plane will seek a single airspeed. A plane which is unstable in pitch will either pitch up into a stall, or nose dive, but won't settle out anywhere in between. A stable airplane will tend to oscillate up and down a few times, but converge on a steady flight speed. Many typical paper airplane designs are stable, but just barely. As a plane becomes more and more stable, it wants to fly faster and faster. To counter this tendency, up elevator must be used to produce a good trim airspeed. This is why many of the classic paper airplane designs are nearly neutrally stable. Few people realize good pitch stability requires a heavy nose and some up elevator. The classic designs rely on the small inherent "up elevator" effect (positive zero lift pitching moment) resulting from the swept wing, and possibly the airfoil shape. Thus many classic paper airplanes can be flown with no elevator adjustment. Sometimes they fly well, many times they don't, and they always have poor stability. The Awesome Paper Airplane Book for Kids by Stefania Luca is aimed at children aged 6-9. It contains instructions for 15 paper airplane designs of varying difficulty, and comes with paper to make them with. The planes are grouped as either Dart Planes, Glider Planes, or Stunt Planes, according to how they behave when you throw them.

Although high aspect ratio wings reduce drag, they also require better building materials. The low strength of paper does not allow the use of high aspect ratio wings.

Paper airplanes are very helpful when you want to illustrate air traffic control guidelines. There was a time when people used the paper airplane to explain and discuss the fundamental parts of real aircraft. People of a certain age may recall buying those fancy "White Wings" in the store made from several sheets of squeezed chipboard paper, and these cutout versions are still paper airplanes too. How to Make a Paper Airplane? A collection of easy-to-fold paper airplane designs and innovative theories of flight, including the author’s Guinness World Record-breaking airplane. Features 16 tear-out model planes. Real airplanes have to be optimized to perform some mission. Since its tough to beat the basic wing/fuselage/tail configuration for aerodynamic efficiency, most planes look that way. The mission of a paper airplane is to provide a good time for the pilot. Sometimes that means the amazement of seeing something radical fly through the air. The combinations of wings, tails, fuselages, and other parts that can be made to fly is endless. Beyond the traditional paper airplane designs there are many exotic shapes that don't look like they should fly. One of these is the "hoop shape", known as the Vortex in my original book. Another exotic shape is in my 1997 calendar called the X-Plane. It is basically two wings attached in the middle and at different angles to form an "X" shape. Other more familiar shapes, but not thought of as airplanes, can also be made to fly. One of these is the Starship from my 1997 calendar, which looks like a futuristic space craft , but it actually flies. With paper airplanes its easy to make airplanes that don't look like real airplanes.

If you ask many people what origami is, they will have a mental picture of birds and animals like the traditional crane, intricate patterned tessellations, or insanely complex creations by Robert Lang or Satoshi Kamiya. It’s usually followed by a comment like ‘I don’t have the patience for that’, or ‘that’s far too complicated for me’. Quite often, those same people have actually already done some origami when they were children – they just didn’t realise it. While there are far more advanced paper airplanes, this one, in my opinion, is the perfect balance of complexity and accessibility for the Average Paper Airplane Joe. It has far more folds than the previous two models, and also flies the best and farthest. Pay attention with this one, folks, and the payoff is well worth it.First, fold the top left corner all the way down so it meets the right edge of the paper. You’ll then unfold, as this will be a guiding crease. The goal for gliding flight is to descend vertically as slowly as possible. This represents the lowest rate of change of potential energy(power) which is the minimum product of drag times velocity. Generally the minimum sink rate for gliders is just above stall, and that's true for paper airplanes as well. For those interested in the details and math, finding the minimum power required involves taking the equation for powered required, differentiating with respect to velocity, and setting this equal to zero (standard calculus procedure for finding the minimum or maximum of a function. Starting with the basic parabolic drag curve;
