Tham khảo sách 'wind tunnels and experimental fluid dynamics research_2', kỹ thuật - công nghệ, cơ khí - chế tạo máy phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | 16 Sport Aerodynamics On the Relevance of Aerodynamic Force Modelling Versus Wind Tunnel Testing Caroline Barelle National Technical University of Athens Greece 1. Introduction In sports events performance analysis is not an easy task since multiple factors such as physiology psychology biomechanics and technical progress in equipment are simultaneously involved and determine the final and ultimate outcome. Identification of individual effects are thus complicated however from a general point of view aerodynamics properties are recognized to play a determinant role in almost every sports in which the performance is the result of the optimal motion of the athlete multi-jointed mechanical system and or is equipment solid system in the air. From ball games like golf baseball soccer football and tennis to athletics alpine skiing cross-country skiing ski jumping cycling motor sport and many others the application of some basic principles of aerodynamic can make the difference between winners and losers. If the general shape of the athlete equipment system in terms of postural strategies and equipment customization is not optimized it can either be made to deviate from its initial path resulting in wrong trajectories and or loss of speed and leading to failure in terms of performance. Coaches should thus be able to assess the aerodynamic efficiency of the motor task performed by the athlete with accuracy and in almost real time. Indeed quick answers and relevant information can help the athlete to focus on specific aspects of his technical behaviour to improve his performance. So far for this purpose two solutions are available . dedicated wind tunnel testing or implementation of aerodynamic force models during the athlete training sessions. According to the complexity of sport performance and the necessity of almost real time answers for stakeholders issue concerning the relevance of aerodynamic force modelling versus controlled experiments in wind tunnel must be .
