Aerodynamics Analysis for an Outdoor Road Cycling Helmet and Air Attack Helmet

Abstract—The study of aerodynamics is very crucial in the world of cycling. Wind tunnel experiment is conducted on most of cycling equipment that is used by a rider and it is a serious factor in the development of cycling sport. This paper represents the aerodynamics analysis of sport cycling helmet and the comparison between a standard road cycling helmet and Air Attack helmet. The test was conducted in a several constant wind tunnel velocity that best reflects the apparent wind velocity that the rider would experience. The test set collects data for 7 different speeds from 3 m/s to 15 m/s. A data set was recorded for each helmet at two different pitch angles which is 0⁰ and 25⁰ angle. The testing result showed that aerodynamic helmets offer drag reduction over a standard road cycling helmet.

Index Terms—Aerodynamic drag, cycling, coefficient of drag, helmets, six component balance, wind tunnel.
