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.
