Abstract

Commercial-off-the-shelf (COTS) aircraft condition monitoring system (ACMS) hardware supports critical health management functionality; real-time event forwarding or recording of any parametric/discrete data can be performed using the digital flight data acquisition unit (DFDAU). The ubiquitous DFDAU is the predominant fielded hardware supporting this important functionality -every 737, 757 and 767 airplane must have the unit installed and the same DFDAU can be used on any of the three aircraft (derivative implementations are on other airplane models). A predominant application of integrated vehicle health management (IVHM) is DFDAU-based flight operation quality assurance (FOQA) and/or engine condition monitoring (ECM) programs, and leveraging this on-going maintenance frame recording and/or Data Link type reporting can lead to dramatically improved IVHM operations. Critical functionality supports ACMS updates or continual maturation prior to a following vehicle mission, and associated Boeing On-Line Diagnostic Reporting (BOLDRtrade) IVHM data bus optimization methods are discussed. All of the aforementioned DFDAU features and future enhancements such as the import of code for sophisticated reasoning are planned for Boeing IVHM Lab prototyping.

使用商用飞机状态监测系统的IVHM解决方案
商用现货(COTS)飞机状态监测系统(ACMS)硬件支持关键的健康管理功能;可以使用数字飞行数据采集单元(DFDAU)进行实时事件转发或任何参数/离散数据的记录。无处不在的DFDAU是支持这一重要功能的主要现场硬件-每架737,757和767飞机都必须安装该单元,并且相同的DFDAU可以在任何三架飞机上使用(衍生实现在其他飞机型号上)。综合飞行器健康管理(IVHM)的主要应用是基于dfdau的飞行运行质量保证(FOQA)和/或发动机状态监测(ECM)程序,利用这种持续的维护框架记录和/或数据链类型报告可以显著改善IVHM操作。关键功能支持ACMS更新或在后续车辆任务之前持续成熟,并讨论了相关的波音在线诊断报告(BOLDRtrade) IVHM数据总线优化方法。所有前面提到的DFDAU功能和未来的增强功能,如导入复杂推理代码,都计划用于波音IVHM实验室原型设计。
