Abstract
The primary objective of a helmet is to provide head protection during fall or accident, however, thermal comfort and aerodynamic efficiency are becoming important design criteria. Helmet with venting generally increases thermal comfort but decreases aerodynamic efficiency. Therefore, an optimal design for helmet is very important in order to satisfy both aerodynamic and thermal efficiency. The primary objective of this work is to study the aerodynamic efficiency and thermal comfort of a series of current production helmets available in Australia. Aerodynamic drag and thermal comfort was measured under a range wind speeds, yaw and pitch angles and compared. Verf.-Referat
