Abstract:Tire bursting is a common aviation accident that easily occurs during aircraft take-off and landing, seriously affecting aircraft safety.In order to minimize the harm of tire bursting to aircraft, the aircraft design characteristics were investigated.On the basis of summarizing the engineering practice of domestic civil aircraft on the latest international tire blasting clauses, and based on the civil aircraft system engineering concept, an aircraft tire blasting design technical system for CS25.734 has been established,and aircraft design technology research has been carried out in four typical stages from project establishment to airworthiness verification.The results showed that: Setting fusible plugs is not a perfect measure to prevent tire bursting. Active or passive design measures should be taken in the aircraft wheel cabin for heat sources to prevent aircraft tires from overheating and bursting; there are four failure modes for aviation tire bursting, and the impact area is related to the compression state of the landing gear ,which is affected by all ground conditions(weight and center of gravity envelope, temperature envelope, etc.);a series of design considerations, verification ideas and compliance criteria on system/structure/fuel fire protection have been verified in the airworthiness certification of a domestic large passenger aircraft,which can provide reference for tire burst protection design of large transport aircraft.
