A Preliminary Investigation into Racing Motorcycle Aerodynamics

Abstract

This paper attempts to guide readers through the development of equipment and related testing procedures at the RMIT University Industrial Wind Tunnel facility designed to replicate and assess flow mechanics relevant to motorcycles. The paper particularly addresses design and development of the preliminary test rig to support both motorcycle and rider. A Cobra probe, the University’s own 13-hole probe and various surface pressure measuring devices are used to analyse near wake and other basic flows pertinent to stakeholders associated with the development of supersports class motorcycles. The test matrix addresses not only various rider configurations but seeks to assess the effect of appendices such as mirrors.
