Flying Gyroscope
A flying gyroscope (also known as a flying cylinder or flying tube) is a cylindrical wing or annular airfoil. It is thrown like a football (ball), football, and can fly very far. The William Mark Corporation invented their flying gyroscope, X-Zylo, in 1993. It was invented by Mark Forti, a Baylor University student, and refined within the aerospace Industry (economics), industry. In 1994, X-Zylo unofficially broke the existing world flying disc distance record when it was thrown . "Toobee, The Amazing Flying Can" is a flying gyroscope developed in 1978. It resembles the top third of an aluminum soda can. A simple flying gyroscope can be folded from a sheet of paper.

Airfoil
An airfoil (American English) or aerofoil (British English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, or turbine. A solid body moving through a fluid produces an aerodynamic force. The component of this force perpendicular to the relative freestream velocity is called lift. The component parallel to the relative freestream velocity is called drag. An airfoil is a streamlined shape that is capable of generating significantly more lift than drag. Airfoils can be designed for use at different speeds by modifying their geometry: those for subsonic flight generally have a rounded leading edge, while those designed for supersonic flight tend to be slimmer with a sharp leading edge. All have a sharp trailing edge. Foils of similar function designed with water as the working fluid are called hydrofoils. The lift on an airfoil is primarily the result o ...
