嵌入式机载性能数据库的搭建与应用

嵌入式机载性能数据库是飞行管理系统的重要组成部分,它是飞机飞行过程中进行性能计算的数据来源,为性能计算提供必要的飞机、发动机性能参数以及操作约束参数,使飞行员可以计算飞机飞行中的各种信息。在嵌入式实时操作系统VxWorks上,使用开源的嵌入式数据库Berkeley DB,搭建了初步满足要求的嵌入式机载性能数据库。而后对数据库的数据内容进行了归纳整理,并初步探讨了性能数据的存储方法。最后通过调用数据库中的图表数据完成了飞机巡航段的性能优化计算,从而验证了性能数据库在实际应用中的可行性。

Construction and Application of Embedded Airborne Performance Database

As an important component of the Flight Management System (FMS), the Embedded Airborne Performance Database provided aircraft parameters, engine performance parameters and operating parameters bound for performance calculation, which could help the pilots calculate flight information during the whole flight. In this paper, we selected the Berkeley DB embedded database and built it in the real-time embedded system VxWorks, thus the performance database was constructed. Then the basic outline of the performan...
