摘　　要：在民用领域,抛放式飞行记录器在国内外尚无系统的研究报告,也无成熟的标准、规范或指南可以借鉴参考。本文提出的计算流体力学(CFD)与六由度运动方程的耦合仿真技术,能较准确地模拟出大部分工况下记录器抛放时的运动轨迹,为记录器离机安全性这一关键技术攻关提供理论依据数据支持,从而有效降低研发成本。In civil area,there is no systematic research focused on Jettisoned FDR in at home and abroad,also not mature standard,specifications and guide.This paper contended the simulation technology of coupling CFD to equations of motion with six degrees of freedom,which can simulate the separation of FDR from the aircraft fundamentally accurately for most working conditions.And it can provide theory basis and data support for the key technology,the safety of separating from aircraft,thus reduce the research and development cost.
