ABSTRACT

Ski jumping, a sport blending athleticism and aerodynamics, has evolved significantly over the past century, with a focus on achieving longer jump distances through optimal aerial posture. This paper delves into the aerodynamic principles governing ski jumping and investigates the historical evolution of jump postures. By employing computational fluid dynamics (CFD), our research aims to provide valuable insights into optimizing the aerial posture of ski jumpers. The literature review showcases the progression of ski jump postures from the early 20th century to contemporary techniques, emphasizing the crucial role of posture maximizing jump distances. Previous studies have elucidated the aerodynamic advantages of the "V" posture, highlighting its ability to minimize resistance and enhance lift, thereby enabling longer flight times and greater distances. Our research methodology involves utilizing CFD simulations to analyze the aerodynamic performance of athletes during ski jumping. By capturing airflow patterns and pressure distributions around the body, we aim to identify key factors influencing jump performance and propose strategies for optimizing posture. Comparing wind tunnel experiments with CFD simulations, we highlight the advantages of the latter in terms of cost-effectiveness, efficiency, and safety. CFD provides a versatile platform for studying fluid dynamics, allowing for precise adjustments of parameters and yielding reliable numerical results. The scope of our research encompasses fundamental fluid mechanics principles, methodology, and practical applications. Through a comprehensive analysis of aerodynamic phenomena and athlete performance, we seek to contribute to the ongoing development of ski-jumping techniques and enhance athletes' competitive edge on the global stage.
