Air drag coefficient of textile-covered elastic cylinders – preliminary aerodynamic studies

This paper presents preliminary experimental results on the influence aerodynamic drag of a cylinder from type (i.e., rigid or soft) and its textile surface. Both soft-body cylinder, with gelatin layer, each five different surfaces were measured in wind tunnel using force measurement technology. The coefficient was determined for several Reynolds numbers. study shows that elasticity has significant airflow type. However, depends respective fabric. With given measurements, no exact statements can yet be made to quantify influence. must studied independently conjunction surface order gain understanding overall system airflow, elastic body.
