Double-CFDに基づくブーメランの飛行特性に関する数値解析

摘要

A simulation taking into account both fluid dynamics and flight dynamics has been conducted for a simple boomerang. The effects of fluid force on the boomerang motion are studied in detail, based on the double CFD method: computational fluid dynamics (CFD) and computational flight dynamics (CFD). From this study, it was found that the centripetal component of the aerodynamics force acting on the boomerang is the major cause that makes the boomerang returns to the initial position.
