Hamilton Sundstrand Selects TTTech to Deliver New Communication Platform for Boeing 787 Dreamliner Systems

Hamilton Sundstrand Corporation has selected TTTech to support the development of a TTP-based data communication platform for use in Hamilton Sundstrand’s electric and environmental control systems on the Boeing 787 Dreamliner. TTTech’s innovative Time-Triggered Protocol (TTP) offers enhanced levels of reliability, availability and safety. In addition, TTP-based systems require less wiring, and consequently they weigh less, than conventional systems. Moreover, TTP allows greater modularity and flexibility than conventional communication systems. The overall result is a reduction of the total life cycle cost for Hamilton Sundstrand’s Common Electronic Architecture (CEA). This cooperation between Hamilton Sundstrand and TTTech is expected to continue as a productive long-term partnership for both companies.

TTTech’s TTP-based solutions provide a maximum level of fault tolerance, safety, and availability. TTP is able to support applications that must effectively monitor operational consistency and detect errors in order to provide the required level of reliability in Hamilton Sundstrand’s Common Electronic Architecture.

"We are very pleased to work together with TTTech,” said Luiz Andrade, Chief Engineer at Hamilton Sundstrand Electric Systems. "The TTP protocol provides Hamilton Sundstrand flexibility in designing distributed electronic systems. By taking advantage of TTP’s modular nature, we can more effectively integrate our systems, improve tolerance to system upgrades, and better manage obsolescence."

Systems integration is especially important to Hamilton Sundstrand since the company is the developer of a broad range of subsystems for the 787 Dreamliner. Beside its component engineering and manufacturing roles, Hamilton Sundstrand will manage the integration of the systems, and will also oversee verification testing and certification. TTP contributes significantly as a facilitator to these activities.

"We are proud that Hamilton Sundstrand has selected TTTech to supply the TTP data bus solution as well as embedded software components for Boeing’s 787 Dreamliner," stated Kurt Doppelbauer, Director Sales Aerospace at TTTech. "Hamilton Sundstrand’s decision demonstrates once more our technology’s leading position for safety-critical systems in the aerospace industry."
