Time triggered protocol/class C(TTP/C) bus has the advantages of high security, good real-time and fast transmission speed. We apply TTP/C bus to more-electric aircraft power distribution system. Firstly, we analyze the structure of distributed automatic power distribution system of more-electric aircraft and the structure and characteristics of TTP/C bus. Then we propose the aircraft distribution system communication network and use dynamic link library to realize communication software programming in C language environment and LabVIEW language environment. Secondly, we provide the offset address selection method to determine the data source direction, and propose data space conversion and format conversion method to improve communication efficiency and reliability. Finally, the test shows that the application technology can realize the TTP/C bus application in the aircraft distribution system, meet the system communication requirements, and improve the reliability and communication speed of the more-electric aircraft communication system.
