Competitive hand-cycling represents a unique case for cycling aerodynamics as the athletes are in a relatively aerodynamic position in comparison to traditional able-bodied cyclists. There are some aerodynamic similarities between both cycling disciplines, including wheel designs and helmets. The lack of research in hand-cycling aerodynamics presents the potential for significant improvements. This research analysed the aerodynamics of competitive hand-cycling under crosswind conditions using wind-tunnel experiments and Computational Fluid Dynamics (CFD) simulations. A range of yaw angles from 0 degrees to 20 degrees in 5 degrees increments were investigated for two separate hand-cycling setups; a road race and a time-trial setup. A maximum drag increase of 14.1% was found from 0 degrees to 15 degrees yaw, for a hand-cyclist equipped for a road race. The three disk wheels used for the TT setup had a large impact on the lateral forces experienced by the TT hand-cyclist. At just 5 degrees yaw and at 15 m/s, the drag and lateral forces for the TT setup matched closely, while this event did not occur until 15 degrees yaw at the same velocity for the road setup. For 20 degrees yaw, the ratio of the lateral force to drag force was 1.6 and 5.6 for the road and TT setups respectively.
