Pan American Airways offered to fly designs of paper airplanes that originated in Japan to the contest. He entered and, out of 12,000 entries from 28 countries, won in two categories: duration and distance. [3] His designs have sold millions throughout Japan and the world. He is the author of a multi-volume work on high-performance paper ...
A simple folded paper plane Folding instructions for a traditional paper dart. A paper plane (also known as a paper airplane or paper dart in American English, or paper aeroplane in British English) is a toy aircraft, usually a glider, made out of a single folded sheet of paper or paperboard.
The Kline–Fogleman airfoil or KF airfoil is a simple airfoil design with single or multiple steps along the length of the wing. It was originally devised in the 1960s for paper airplanes. In the 21st century the KF airfoil has found renewed interest among hobbyist builders of radio-controlled aircraft, due to its simplicity of construction. [1]
As ship design evolved from craft to science, designers learned various ways to produce long curves on a flat surface. Generating and drawing such curves became a part of ship lofting; "lofting" means drawing full-sized patterns, so-called because it was often done in large, lightly constructed mezzanines or lofts above the factory floor.
Another form of the Möbius strip, called the cross-cap or crosscap, also has a circular boundary, but otherwise stays on only one side of the plane of this circle, [57] making it more convenient for attaching onto circular holes in other surfaces. In order to do so, it crosses itself.
Of all the early operators of military aircraft, Germany was unusual in not using circular roundels. After evaluating several possible markings, including a black, red, and white checkerboard, a similarly coloured roundel, and black stripes, it chose a black 'iron cross' on a square white field, as it was already in use on various flags, and reflected Germany's heritage as the Holy Roman Empire.

Cross was born in Camberwell, London on 23 April 1924. [2] He was mainly self-taught, learning his craft at the Camberwell School of Art and as a technical illustrator for training manuals for Fairey Aviation during the Second World War. He progressed from there to producing advertising art for the aircraft industry and other companies.
