Numerical study of the aerodynamic properties of a flying, rotating disc-wing

Flying, rotating disc-wings (FRDW) are classified as axi-symmetric, thin cylindrical structure that utilizes spinning to maintain flight stability. The most commonly-seen example of FRDW is on Frisbee sport. In fact, this unique structure has sparked the interest of researchers over the years to stu...

description Flying, rotating disc-wings (FRDW) are classified as axi-symmetric, thin cylindrical structure that utilizes spinning to maintain flight stability. The most commonly-seen example of FRDW is on Frisbee sport. In fact, this unique structure has sparked the interest of researchers over the years to study its aerodynamic properties as well as develop similar flying vehicles. Wind-tunnel experiments were the most conventional methods used in the past to study its aerodynamics. The main objective of this study is to study the aerodynamic properties of FRDW using Computational Fluid Dynamics (CFD). This is an alternative method to be introduced and is especially useful and cost-saving when it comes to preliminary design of a flying machine.
