The effect of vertical axial wind on the flight stability in ski jumping

Stability in flight is essential for performance and safety in ski jumping. However, the effect of vertical axial wind on the flight stability in ski jumping remains unknown. In this study, the effect of vertical axial wind on the flight stability was analyzed by computational fluid dynamics (CFD) simulations. The wind affected flow field characteristics around the system, thus the corresponding force and torque were produced. The influence of vertical axial wind on the flight stability of ski jumping can’t be ignored, which can cause the athletes to deviate from the flight trajectory and possibly rotate. The results have some application value to improve the safety of ski jumping, and also provide useful scientific guidance for the flight stability control training of athletes.
