    Parker Aerospace selects TTTech's TTP solution for new fly-by-wire actuation platforms

    July 14, 2010
    CARLSBAD, Calif., 14 July 2010. Parker Aerospace selected TTTech to provide an integrated communication solution based on Time-Triggered Protocol (TTP) for Parker's new generic fly-by-wire actuation platforms. Initial applications of this platform will be on the Bombardier CSeries and Embraer Legacy 450/500 aircraft programs.
    Posted by John McHale CARLSBAD, Calif., 14 July 2010. Parker Aerospace selected TTTech to provide an integrated communication solution based on Time-Triggered Protocol (TTP) for Parker's new generic fly-by-wire actuation platforms. Initial applications of this platform will be on the Bombardier CSeries and Embraer Legacy 450/500 aircraft programs. TTP is an open industry standard and promoted within the Society of Automotive Engineers (SAE) standards body as "AS6003 TTP Communication Protocol." It offers higher bandwidth compared to CAN, MIL STD-1553, and ARINC 429 and provides significant advantages in terms of reliability, modularity, lower weight, certification, reduced cost, and faster time to market for aerospace systems, TTTech officials say. Parker supplies fly-by-wire flight control systems for all new Bombardier aircraft programs requiring this technology for a period of 10 years -- the 10 year period began in 2008. "We are committed to building the best digital fly-by-wire platform in the industry and have selected the most advanced, yet mature solution available to provide increased reliability, reduced development cycle, and an overall improved value proposition," says Mark Seidel, Parker Aerospace Control Systems Division vice president and general manager. "Parker's fly-by-wire flight control system distributed architecture necessitates the need of a deterministic, highly reliable and high-bandwidth databus for interconnecting all the electronics elements as the backbone of the flight control system. The TTP databus from TTTech offers all the necessary ingredients of such a databus and includes the adaptability and portability features allowing for the use of common electronics elements on multiple platforms." Modular embedded computing platforms based on TTP offer the same set of benefits as integrated modular avionics, but in a completely distributed system. They help to reduce the design and system integration effort, costs for upgrades, incremental modernization, and obsolescence management, company officials say. With TTP, modular certification and system reuse on different aircraft platforms is supported. Through the reuse of TTTech's solutions in the aerospace industry, Parker will benefit from substantial risk and cost reduction as well as faster time-to-market. The TTP-based communication platform is a mature DO-254/DO-178B Level A solution for design of critical embedded systems. It consists of a set of controllers, a physical layer, design/verification tools, embedded middleware components, and production testing equipment to cover all program lifecycle needs.
