The wings and stabilizers of fixed-wing aircraft, as well as helicopter rotor blades, are built with airfoil-shaped cross sections. Airfoils are also found in propellers, fans, compressors and turbines. Sails are also airfoils, and the underwater surfaces of sailboats, such as the centerboard, rudder, and keel, are similar in cross-section and operate on the same principles as airfoils. Swimming and fl… 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, 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. In 1994, X-Zylo unofficially broke the existing world flying disc distance record when it was thrown 655 feet (200 m).
