在速降滑雪比赛中，人体测量和空气动力学条件是决定运动员表现的重要因素。本文将理论方法与风洞实验输入数据相结合，估计了所选变量对滑雪速度的影响。感兴趣的变量是运动员的质量和空气动力，阻力和升力。在研究结果的基础上，引入了人体测量码（ACN）。这个ACN值是滑雪者的质量、阻力系数和运动员暴露在气流中的最大投影面积的组合。为了比较风洞试验的结果，ACN似乎是一个有效的、易于计算的数字。
The anthropometric and aerodynamic conditions are among the important factors that decide performance in downhill ski races. This paper combines a theoretical approach with input data from wind tunnel experiments to estimate the influence of selected variables on speed in skiing. The variables of interest are the mass of the athlete and the aerodynamic forces, drag and lift. Based on the findings of the study, an anthropometric code number (ACN) is introduced. This ACN value is a combination of the mass of the skier, the coefficient of drag, and the greatest projected area the athlete exposes to the airflow. It seems that the ACN is a valid, easy-to-calculate number in order to compare test results from wind tunnel experiments.
