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.
On September 5, 2024, three paper planes, one of which was equipped with a radiosonde, were launched from Italy using a weather balloon. The launch reached an altitude of 41,889 meters. [14] The telemetry plane landed in the sea after 1 hour and 59 minutes of flight. One of the other two paper planes was found a week later. [15]
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.
NASA flew zero gravity flights on various aircraft for many years. In 1959 Project Mercury astronauts trained in a C-131 Samaritan aircraft dubbed the "vomit comet". [23] Twin KC-135 Stratotankers were used until December 2004 and later retired. One, a KC-135A registered N930NA (also known as NASA 930, formerly USAF serial no. 59-1481), flew ...
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 ...
Under certain mathematical premises of the fluid, there can be extracted a mathematical connection between power, radius of the propeller, torque and induced velocity. Friction is not included. The blade element theory (BET) is a mathematical process originally designed by William Froude father of Robert Edmund Froude (1878), David W. Taylor ...
Advanced Supersonic Transport (AST) model in wind tunnel. The aircraft design process is a loosely defined method used to balance many competing and demanding requirements to produce an aircraft that is strong, lightweight, economical and can carry an adequate payload while being sufficiently reliable to safely fly for the design life of the aircraft.
Research, X-Planes, Environmentally Responsible Aviation Project [12] Retired (1) Armstrong Flight Research Center: X-48 series was utilized to "evaluate the low-speed stability and control of a low-noise version of a notional hybrid-wing-body design." NASA is hoping that this particular aircraft will aid in the design "green airlines."
