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]

Dactylopatagium: the portion found within the digits; Plagiopatagium: the portion found between the last digit and the hindlimbs; Uropatagium: the posterior portion of the body between the two hindlimbs; Other mammals such as gliding possums and flying squirrels also glide using a patagium, but with much poorer efficiency than bats. They cannot ...
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]
Paper airplane day celebrations typically include social gatherings at which participants create and fly paper airplanes. These events often feature contests in two basic flight categories: "distance" and "time in air". As of 2012, Takuo Toda holds the world record for the longest time in air (27.9 seconds). [2] The distance record (226 feet ...
