Certified Flight Products for Reliable Networks

Airliners expect the new generation of aircraft to reduce operating costs by 20% and more, working in an extremely competitive business environment. New regulations also contribute to increased pressure on aircraft manufacturers. Therefore, OEMs invest heavily in advanced technologies for cutting costs, reducing fuel consumption and weight. Furthermore, there is a trend towards maintaining high levels of air transport safety and improved passenger comfort. The key potential for improved efficiency lies in new materials, efficient engines, more electric systems, and advanced system integration.

System integration and reduction of system complexity by TTP
In new aircraft programs, data buses can be one of the key technologies to support a shorter time-to-market and improve program profitability. The time-triggered fieldbus TTP and its DO-254 certifiable chip IP have the potential to significantly impact the design of modern avionics and control systems. It supports the reduction of system complexity, thus lowering design and integration effort. Moreover, TTP facilitates data distribution between integrated modular avionics (IMA) and subsystems. TTP is already used in several aircraft production programs.

Scalable and safe Ethernet applications
In aviation applications, onboard systems and sensors should be integrated in advanced architectures for improved survivability and high computing performance. System integrity and fault tolerance can be scaled to application and system platform needs. Future solutions support congestion-free transfer of large data volumes and can be used to integrate legacy networks. These products can be based on TTEthernet, a scalable, open, real-time Ethernet platform.

FlexRay support
The TTTech subsidiary TTTech Automotive fully supports the time-triggered fieldbus FlexRay. The FlexRay license agreement is currently for automotive use only. The FlexRay core partners are working on a license agreement for non-automotive use.
