Development of Design Methodology to Meet Uncontained Rotor Burst Airworthiness Requirements
Uncontained Rotor Burst (URB) has resulted in high velocity fragment penetrating the adjacent critical system and structure components andbrings considerable damage on the airplane. Since it is unlikely that uncontained rotor failures can be completely eliminated, airworthiness regulations CCAR/FAR/CS-25 require that design precautions should be taken to minimize the hazard of URB form the aircraft design point of view. There is specific method of compliance AC/AMC20-128A to provide an outline for minimizing the hazard, but practical experience shows that more specific design method and procedure are needed for engineering application. The methodology in this study is developed based on AC/AMC20-128A to produce a detailed guidance on URB minimization by providing a logical design procedure and method explanation. To complete the AC/AMC for engineering application, the means of critical component identification from the process of System Safety Assessment is given; the criteria of performing corrective actions after qualitative analysis is proposed; the quantitative analysis method combined with Fault Tree Analysis is finally provided.
