The thermal strain imposed on helicopter aircrew by chemical protective (NBC) clothing in summer in Germany has been assessed in a laboratory simulation. The environmental conditions used were dry bulb temperature 35 degrees C, wet bulb temperature 19 degrees C and a wind speed of 2.0 m X s-1. The NBC equipment imposed a significant thermal strain on the crewman when compared with standard summer flying clothing, but not on the pilot whose tasks involve lower energy expenditures. Deep body temperature exceeded 37.6 degrees C and a significant degree of dehydration (1% of body weight) also occurred, despite the availability of a drinking facility in the respirator. It is recommended that the only practical way of preventing thermal strain in helicopter crewmen under NBC conditions is by providing personal conditioning.
在德国，通过实验室模拟对夏季直升机机组人员穿着化学防护服（核生化防护服）时所承受的热应激进行了评估。所采用的环境条件为干球温度35摄氏度、湿球温度19摄氏度以及风速2.0米每秒。与标准夏季飞行服相比，核生化防护服给机组人员带来了显著的热应激，但对任务涉及较低能量消耗的飞行员而言并非如此。尽管呼吸器中有饮水设施，但深部体温仍超过37.6摄氏度，且出现了显著程度的脱水（体重的1%）。建议在核生化条件下预防直升机机组人员热应激的唯一可行方法是提供个人调温装备。
