摘　　要：民用涡扇发动机短舱作为动力装置火区的外部边界,必须起到火焰的隔离和包容作用,以免火焰窜出短舱蔓延至机翼油箱等重要部位,对飞行安全造成严重威胁。随着民用飞机安全性要求的不断提高,适航当局对动力装置的防火设计提出了越来越严格的要求。文章从火区分类出发,研究短舱火区及可燃液体泄漏区的防火设计。As the outer boundary of the fire zone of the power plant,the civil turbofan engine cabin must play the role of flame isolation and containment,so as to prevent the flame from escaping the nacelle and spreading to important parts such as the wing fuel tank,which poses a serious threat to flight safety.With the continuous improvement of the safety requirements of civil aircraft,the airworthiness authorities have put more and more strict requirements on the fire protection design of power plants.Based on the classification of fire zones,this paper studies the fire protection design of short cabin fire zones and combustible liquid leakage zones.
