摘要

波音商用飞机集团在其777客机上认证了全新的集成容错空气数据和惯性参考系统(FT-ADIRS)。FT-ADIRS由容错空气数据和惯性参考单元(FT-ADIRU)、副姿态和空气数据参考单元(SAARU)和6个空气数据模块(adm)组成。开发了用于系统设计、验证和确认的新流程。FT-ADIRS冗余管理和系统性能通过一种独特的流程进行验证,该流程通过实际生产单元重播飞行记录的传感器数据。故障以蒙特卡罗方式插入,以演示惯性导航和空气数据功能实时隔离和幸存传感器故障的能力。

The Boeing 777 Fault Tolerant Air Data and Inertial Reference System-a new venture in working together
The Boeing Commercial Airplane Group has certified an all-new, integrated Fault Tolerant Air Data and Inertial Reference System (FT-ADIRS) on its 777 airliner. The FT-ADIRS consists of the Fault Tolerant Air Data and Inertial Reference Unit (FT-ADIRU), the Secondary Attitude and Air Data Reference Unit (SAARU), and six Air Data Modules (ADMs). New processes for the design, verification, and validation of the system were developed. The FT-ADIRS redundancy management and system performance were validated using a unique process whereby flight-recorded sensor data were replayed through actual production units. Faults were inserted in a Monte Carlo fashion to demonstrate the ability of the inertial navigation and air data functions to isolate and survive sensor faults in real-time.
