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.
Time published an April 2, 1973 article, The Paper-Plane Caper, [2] about the paper airplane and its Kline–Fogleman airfoil. Also in 1973, CBS 60 Minutes did a 15-minute segment on the KF airfoil. CBS reran the show in 1976. [citation needed] In 1985, Kline wrote a book entitled The Ultimate Paper Airplane. [3]
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 ...
By RYAN GORMAN A paper airplane set a new Guinness world record as it flew 82 miles this month. A team of auxiliary U.S. Air Force volunteers launched the paper aircraft from a weather balloon ...
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]
Aeronautics is the science or art involved with the study, design, and manufacturing of air flight-capable machines, and the techniques of operating aircraft and rockets within the atmosphere. While the term originally referred solely to operating the aircraft, it has since been expanded to include technology, business, and other aspects ...
The wing, horizontal stabilizer, vertical stabilizer and propeller/rotor blades of an aircraft are all based on aerofoil sections, and the term chord or chord length is also used to describe their width. The chord of a wing, stabilizer and propeller is determined by measuring the distance between leading and trailing edges in the direction of ...
The three axis of rotation in an aircraft. Flight dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of gravity (cg), known as pitch, roll and yaw.
