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 planes were to have been made from heat-resistant paper treated with silicon. [5] As the Japanese/JAXA project was outlined, scientists would have had no way to track the airplanes or to predict where they might land; and as 70% of the Earth's surface is covered in water, the craft would have anticipated a wet reunion with the planet. Each ...
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] But it has not been adopted for full-size aircraft capable of carrying a pilot, passengers, or other substantial payloads.
The Paper Aircraft Released Into Space (PARIS) project was a privately organized endeavour undertaken by various staff members of the British information technology website The Register to design, build, test, and launch a lightweight aerospace vehicle, constructed mostly of paper and similar structural materials, into the mid-stratosphere and recover it intact.
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 ...
The last sentence on "free-fall" of paper airplane on the surface of the earth sounds not right. In the space, the space station including the air and the paper airplane inside is in free fall as a whole, and thus the paper airplane feels zero gravity. This is not the case on the earth.

The mean radius in astronomy is a measure for the size of planets and small Solar System bodies. Alternatively, the closely related mean diameter ( D {\displaystyle D} ), which is twice the mean radius, is also used.
General parameters used for constructing nose cone profiles. Given the problem of the aerodynamic design of the nose cone section of any vehicle or body meant to travel through a compressible fluid medium (such as a rocket or aircraft, missile, shell or bullet), an important problem is the determination of the nose cone geometrical shape for optimum performance.
