A series of wind tunnel tests was conducted on selected fire fighter helmets to identify design factors which affect helmet ventilation at various air velocities and head orientation angles. Biomedical heat flux transducers were mounted on the surface of an electrically heated mannequin head to monitor convective heat loss. Under the experimental conditions, specific helmet design features were identified which can contribute to improved helmet ventilation and thus improve body metabolic heat loss. Attention to helmet design and helmet suspension systems is recommended to reduce fire fighter heat stress.
对选定的消防员头盔进行了一系列风洞试验，以确定在不同风速和头部朝向角度下影响头盔通风的设计因素。生物医学热通量传感器安装在电加热人体模型头部表面，以监测对流热损失。在实验条件下，确定了特定的头盔设计特征，这些特征有助于改善头盔通风，从而减少身体代谢热损失。建议关注头盔设计和头盔悬挂系统，以减轻消防员的热应激。
