运输类飞机可生存坠撞后的火灾是客舱安全范畴内的重要问题之一。提高机身抗烧穿性,即推迟火焰进入客舱的时间,可为乘员应急撤离提供时间保证。介绍了运输类飞机坠撞后的池火火焰特征,包括最高温度、热流密度等特征的范围及其影响因素,重点论述了机身结构烧穿过程,剖析了适航规章中的抗烧穿符合性判据,梳理了抗烧穿性试验方法的发展过程,最后对我国未来运输类飞机机身抗烧穿研究的发展进行了展望。
One of the most important issues in cabin safety is the survivability of a crashed fire by transport aircraft. Improve the body burn resistance, that delay the flame into the cabin time, for emergency evacuation to provide time assurance. The characteristics of pool fire flame, including the maximum temperature and heat flux density, after the collision of transport aircraft were introduced, and their influencing factors were discussed. The burning through process of the fuselage structure was mainly discussed, and the anti-burn wear of airworthiness regulation was analyzed Sexual criteria, combing the development of test methods for burn-through resistance, and finally forecast the development of anti-burn-through research on fuselage of future transport-type aircraft in China.
