摘要
在康定机场和四川省广汉市进行对比燃烧试验,测量飞机机舱内织物的燃烧时间、燃烧长度及质量损失率。结果表明:在低压条件下,织物燃烧速率降低,且开始燃烧所需的体积氧浓度比常压高8%;同一体积氧浓度下或者燃烧同一时间时,低压下质量损失率小于常压;燃烧同一长度,低压下质量损失率大于常压。研究成果可为低压环境下的飞机舱内火灾预防和早期探测提供理论依据。
Contrast combustion testswere carried out at Kangding Airport and Guanghan, to measure the burning time, burning length and mass loss rate of aircraft cabin fabric. The results showed that, under the condition of low pressure, the burning rate of the fabric decreases, and the volume oxygen concentration required for starting combustion is 8% higher than the standard atmospheric conditions;under the same volume oxygen concentration and same burning time, the mass loss rate under low pressure is less than standard atmospheric conditions;the mass loss rate under low pressure is higher than that of standard atmospheric conditions when the length of fabric burnt was the same. The study can provide theoretical basis for aircraft cabin fire prevention and early detection under the low pressure condition.
