TTTech's Time-Triggered COTS Components in Intertechnique (Zodiac Group) Control Units for Boeing 787.VIENNA, Austria -- TTTech's hardware and software products based on the Time-Triggered Protocol The Time-Triggered Protocol (TTP) was specifically designed to meet all requirements in connection with the implementation of fault-tolerant systems. TTP has its special focus on safety-critical high-speed applications. That results in low costs and a high protocol efficiency. (TTP TTP (thymidine triphosphate): see thymine. [R]) have been selected by Intertechnique (Zodiac Group The Zodiac Group is a French corporation with worldwide presence, specialized in the production and development of aerosafety systems, aircraft systems, airline equipment, airbags, remote transmissions, boats and swimming pools, however they are best known for their widely used ) for the development of its Electrical Load If an electric circuit has a well-defined output terminal, the circuit connected to this terminal (or its input impedance) is the load. (The term 'load' may also refer to the power consumed by a circuit; that topic is not discussed here. Control Units (ELCUs) for the electronic power system in the Boeing 787 Dreamliner. The Zodiac Group is a leading supplier of power distribution systems in the aerospace industry. Its TTP-based control units will be integrated by Hamilton Sundstrand Hamilton Sundstrand, is a global corporation that manufactuers and supports aerospace and industrial products for worldwide markets. It was formed from the merger of Hamilton Standard and Sundstrand Corporation in 1999. Corporation in the Dreamliner's Electric Power Generation and Start System (EPGSS). The Electric Power Generation and Start System is a key element of the Boeing 787 Dreamliner as it controls, distributes and protects the aircraft's electric power. Maximum levels of safety and strict determinism are required for this application. "We are pleased to work together with TTTech for designing control units based on the Time-Triggered Protocol," said Arnaud-Xavier Veaux, Project Manager at Intertechnique. "Through this cooperation we are looking forward to serving Hamilton Sundstrand and Boeing with the best value for their power generation system." TTTech's commercial off-the-shelf (COTS) software components reduce development costs for safety-critical applications. They are certifiable cer·ti·fi·a·ble adj. 1. That can or must be certified. Used of infectious, industrial, and other diseases that are required by law to be reported to health authorities. 2. in compliance with the RTCA RTCA Radio Technical Commission for Aeronautics RTCA Rivers Trails and Conservation Assistance (National Park Service) RTCA Rio Tinto Coal Australia RTCA Requirements and Technical Concepts for Aviation software standard DO-178B Level A. The data loading solution that TTTech provides to Intertechnique for the ELCUs was developed according to the most stringent aerospace industry guidelines for safety-critical software design. By choosing TTTech's time-triggered solutions, Intertechnique adds maximum fault tolerance and availability to their ELCUs. TTP is able to support applications that must effectively monitor operational consistency and detect errors in order to provide the required level of reliability. This technology is a major technological achievement in the area of distributed embedded computing and networking and has attracted a significant amount of attention in a wide range of industries where high reliability, availability, safety and stability are key requirements. "With Intertechnique basing their products for this important program on our technology, another major European system supplier uses the time-triggered approach to enable more modular and more electric aircraft," says Andreas Eckel, Manager Aerospace Sales Europe at TTTech. |
