| 英文摘要: |
| In order to improve the electromagnetic radiation resistance performance of the engine control system and reduce the mass
of the system's transmission cables, a fiber optic system reconfiguration and transmission scheme based on a full-authority digital
electronic control system was proposed, and the research on fiber-optic data transmission technology was carried out. The scheme that
consists of a complete set of fiber optic links was designed, the hardware of the fiber optic components was fabricated, and the fiber optic
transmission path was established between the main and backup systems. The designed fiber optic transmission links were verified by
semi-physical and whole engine tests. The results show that fiber optic transmission technology can be used for signal transmission of an
aeroengine control system, and the designed fiber optic transmission links can withstand the harsh mechanical environment of the engine
and transmit the data stably and reliably; when part of the main system fails, the backup system signal can be obtained through fiber optic
transmission, achieving fault reconstruction of the main control system and improving system reliability. This research will provide techni?
cal experiences for developing next-generation distributed control systems in the future. |
