Time-Triggered Network Applications Selected
TTP is an open industry SAE standard, AS6003. It offers higher bandwidth compared to CAN, MIL Std-1553 and ARINC 429 buses and, TTTech said, provides advantages in terms of reliability, modularity, lower weight, certification, reduced cost and faster time to market.
Bombardier in July 2008 selected Parker Aerospace as exclusive supplier of fly-by-wire flight control systems for new Bombardier aircraft programs for a period of 10 years.
TTTech also announced the delivery of a Distributed Integrated Modular Avionics (IMA) test bed to Sikorsky Aircraft Corp., which is working on a proof-of-concept for a new generation of modular, reusable and scalable Vehicle Management System.
The Distributed IMA test bed features an approach that integrates a high-bandwidth time-triggered network and a ARINC 653 partitioned operating system, Wind River’s VxWorks 653, enabling the system “to operate as a fault-tolerant hard real-time distributed computer hosting time-, mission- and safety-critical functions,” TTTech said.
