Research on Football Flight Trajectory Based on Aerodynamic

Abstract

The purpose of this research is to play football due to the effects of various conditions causing the ball to the rotation curves of the basic characteristics of the evaluation, and then from the air dynamics study of air in the ball rotation changes is how to affect ball flight. This article through two experimental test to investigate the football in the aerodynamic characteristics. In the first experiment, the hypothesis of a football not rotates at different speeds, start, and measurement and analysis of every ball flight trajectory. Second experiments using the same firing speed launched the football, but with a different spin conditions (in all cases to the axis of rotation is horizontal). Again, on each flight trajectory measurement drag lift coefficient. This information is used to simulate the three typical game and foot shocks, but also to the offset distance and weather conditions were measured.
