分析了BKK－15K一体化飞行防护装备（简称BKK－15K）通风结构、通风阻力及散热作用。通风结构均为囊式，通风管分布在7个抗荷囊的下面或侧面。通风阻力在通风流量100L／min和200L／min时分别为0．47和1．87kPa。在环境温度（Tdb）40℃、持续时间90min条件下，对照组有较明显的热应激、通风Ⅰ组和通风Ⅱ组分别维持Ts34．1℃和33．6℃左右，大腿皮肤温度可低于30℃，但Tr都升高0．4℃。该结果表明，这套装备可显著减轻飞行员热应激。
The ventilation structure, ventilation resistance and heat dissipation of BKK-15K integrated flight defense equipment (BKK-15K) were analyzed. Ventilation structure are capsule, ventilation tube distribution in 7 anti-charge capsule below or side. Ventilation resistance was 0.47 and 1.87 kPa at 100 L / min and 200 L / min, respectively. Under the conditions of 40 ℃, 90min ambient temperature (Tdb), the control group had obvious heat stress. The ventilated group Ⅰ and the ventilated group Ⅱ maintained Ts34.1 ℃ and 33.6 ℃ respectively, while the thigh skin temperature was lower At 30 ° C, Tr increased by 0.4 ° C. The results show that this set of equipment can significantly reduce pilot thermal stress.
