- The shape of the disc is an airfoil in cross-section which allows it to fly by reducing the drag and increasing lift as it moves through the air, compared to a flat plate. Spinning the disc imparts a stabilizing gyroscopic force, allowing it to be both aimed with accuracy and thrown for distance.

In order to explain the physics of flying discs, we will first review some basics that we will need in our discussions. The two major ideas are (using terms from popular science) “Gyroscopic Inertia” and the “Bernoulli Principle”. In Section3 we will put these ideas together to describe how Frisbees fly. Following an argument of Shapiro

The flying disc was popularized by the toy company Wham-O with its introduction of the trademarked "Frisbee" in 1957. This remarkable feat of aerodynamics and gyroscopic stability was discovered rather than predicted. The physics of its flight is subtle and remarkable.
Why does a flying disc fly really well, say compared to a disc that doesn't rotate when it flies? Well, the real answer is that physics in the name of lift, angular momentum, and gyroscopic precession become involved.
A frisbee (pronounced / ˈ f r ɪ z b iː / FRIZ-bee), also called a flying disc or simply a disc, is a gliding toy or sporting item that is generally made of injection-molded plastic and roughly 20 to 25 centimetres (8 to 10 in) in diameter with a pronounced lip.
I hope to clearly explain the physics of flying discs (commonly called Frisbees). After discussing the basic physics behind the problem, we will explore a few interesting details using ideas from class.
Three types of golf discs and four sets of simpler parametric discs were studied to analyze and isolate the effect of design factors on these aerodynamic characteristics. Full six degree-of-freedom simulations of the discs were performed to visualize their flight trajectories and attitudes.
May 24, 2015 · The physics of frisbee flight. While in flight, our frisbee will experience several forces governing its movement including gravity, lift, drag, and a torque from its angular momentum. We will quickly look at each of these, but we are not going to fully model the system (though it could be fun!) Forces on a frisbee.
