Technology analysis and system scheme for aero-engine distributed control system

The status, progress and technology readiness level of the system architecture, communication bus, smart components, high temperature electronic components and power bus for aero-engine distributed control system were analyzed and evaluated. The results show that the studies for aero-engine distributed control system are at fundamental phase and the technology readiness level (TRL) is TRL 1 to TRL 2. According to the analysis and evaluation aforementioned, two potential schemes of distributed control system for a turbofan were proposed, including transitionally distributed control and partially distributed control based on TTCAN bus, and the system architectures, control functions and communication traits were discussed, providing a reference for future development of the aero-engine distributed control system.
