TTTech’s Deterministic Ethernet Successfully Contributes to SA²GE IMA Demonstration Project

TTTech’s TTEthernet products successfully contributed to the SA²GE technology demonstration project, a public-private initiative for a greener aircraft. The sub-project “Integrated Modular Avionics for Critical Systems” demonstrated systems integration on an Integrated Modular Architecture (HIS-IMA) platform, based on Deterministic Ethernet (SAE AS6802, ARINC 664 p7 and ARINC 653-compliant RTOS). TTTech worked with Bombardier, Thales Canada and École Polytechnique de Montréal to implement the high integrity, high reliability networked computing platform.

The interoperability of TTEthernet and ARINC 664 p7 products from different suppliers using different traffic classes (Time-Triggered Ethernet, ARINC 664 p7 and standard Ethernet) on the same network infrastructure was successfully demonstrated through the project. The subset of three mixed criticality systems were implemented on the HIS-IMA platform, using different computer hardware and different ARINC 653 operating systems, all communicating on the same network using different kinds of Deterministic Ethernet traffic.

"The success of this project clearly demonstrates the use and benefits of Deterministic Ethernet (Time-Triggered Ethernet, ARINC 664 p7 and standard Ethernet) on a single network infrastructure, creating the scalability and modularity needed for future aircraft network designs," states Perry Rucker, Director of Sales & Operations for the Americas at TTTech North America Inc. "We would like to thank our partners for the successful completion of the project and we are looking forward to continue working with them on the next phase to further implement TTEthernet solutions in the next-generation aircraft critical vehicle systems network."

The SA²GE sub-project IMA for Critical Systems started in 2010 and was completed in 2015, culminating in the demonstration of a fully functioning real-time architecture, utilizing a representative set of aircraft system functions and components.
