Paper Aeroplane Toy Build Guide

After the folding there are still gaps between different layers of folded paper (tearoff edge). These and the kinks transversal to the airflow may have a detrimental effect on aerodynamics, especially on the upper side of the wing. In some models the surfaces are not aligned to the direction of flow acting as airbrakes. Typically the center of mass is at 1/81 and the center of area is at 1/2 of the plane lengths. Two methods exist to shift the center of mass to the front. One rolls up the leading edge which then stays unswept. The other uses a swept wing or axial folding to produce something like a fuselage extending out of leading edge of the wing.
Space flight
There may one day be a paper plane launched from space. A prototype passed a durability test in a wind tunnel in March 2008, and Japan's space agency JAXA considered a launch from the International Space Station. However, the plane developers, Taduo Toda and fellow enthusiast Shinji Suzuki, an aeronautical engineer and professor at Tokyo University, postponed the attempt after acknowledging it would be all but impossible to track them during the planes' week-long journey to Earth, assuming any of them survived the searing descent. The developers continue, in 2009, with hopes that China or Russia will back further efforts on the project. In February 2011, 200 planes were launched from a net underneath a weather balloon twenty-three miles above the Earth's surface. The planes were specially designed to maintain stable flight even during windgusts up to 100 mph. The planes were equipped with data chips that can be plugged into a computer and have the data uploaded onto a website. Planes have been found in many places including Europe, Canada and possibly South Africa.
