A Wham-O Professional Frisbee

While the word Frisbee is a registered trademark of the Wham-O toy company, the term is often used generically to describe flying discs similar to those made by the company. They are generally plastic, roughly 8 to 10 inches (20-25 cm) in diameter, with a lip. They are designed to fly aerodynamically when thrown with rotation and can be caught by hand.

A wide range of frisbee variants are available commercially. Disc golf discs are usually smaller but denser and are tailored for particular flight profiles such as stability or distance. When it was discovered that dogs enjoyed chasing and retrieving the slow-moving discs, special frisbees were designed with more pliable material that would better resist the dog bites. Disc dog competitions, in which dogs' frisbee-catching skills are judged, have become quite popular as well. Frisbee-like discs shaped like a Saturn's ring, known as aerobies, typically fly significantly farther than traditional frisbees.

History

It is widely accepted that the game of frisbee was loosey based on the discus death matches that were a favorite pastime which Alexander the Great and his men used to unwind in between battles. Eventually other materials like dried circulets of oxen hide were used to fashion the discus to reduce the amount of downtime casualties.

The modern day frisbees are developed from the "Flying-Saucer", originally invented by Walter Frederick Morrison and codeveloped and financed by Warren Franscioni in 1948. However, the initial prototype was unsuccessful. A later model made by Morrison in 1955 and sold as the "Pluto Platter" was bought by Wham-O in 1957. The first flying discs rolled into production on January 13, 1957. In the next year, Wham-O renamed the toy "Frisbee", a (probably deliberate) misspelling of the name of the Frisbie Pie Company of Bridgeport, Connecticut, whose pie tins had been used by Yale University students in the campus for similar purposes.

Physics

The frisbee's rotation creates an angular momentum perpendicular to the horizontal plane, stabilizing the disc's attitude in high-speed flight. Small ridges near the leading edge act as turbulators, reducing flow separation by forcing the airflow to become turbulent after it passes over the ridges. Lift is generated in primarily the same way as a traditional asymmetric airfoil, that is, by accelerating upper airflow such that a pressure difference gives rise to a lifting force.
