VIENNA, Austria -- (BUSINESS WIRE) --

TTTech, the leading supplier of dependable networking solutions based on time-triggered technology, has delivered a Distributed Integrated Modular Avionics (IMA) test bed to Sikorsky Aircraft Corporation, a subsidiary of United Technologies Corp. (NYSE:UTX). Distributed IMA is a class of integrated architectures which inherits all benefits of Integrated Modular Avionics based upon the ARINC 653 avionics standard, and enables the efficient design of distributed systems with mixed criticality applications. Distributed IMA based on the TTEthernet protocol can significantly control system complexity while facilitating designs of advanced and reliable electronic systems with lower life cycle costs.

Sikorsky Aircraft is working on a proof-of-concept for the new generation of modular, reusable, and scalable integrated vehicle management system. In contrast to existing IMA systems, hard real-time control loops and isochronous audio and video can reside in the same network with other critical and non-critical functions and operating systems.

For the integration of hosted functions on different end systems, Sikorsky has selected TTEthernet (SAE AS6802 Time-Triggered Ethernet) as a deterministic, high-speed, fault-tolerant 1 Gbit/s backbone network.

"This type of distributed IMA eliminates conflicts in flexible integration of critical and non-critical functions in distributed systems," said Bill Kinahan, Software Systems Technical Fellow of Sikorsky Aircraft. "The technology does not impose constraints on distribution or centralization of functions, and therefore we can do what is necessary to optimize our integrated systems."

"Time-triggered technologies enable design of mixed criticality distributed systems and platforms for next generation avionics using COTS components today," says Kurt Doppelbauer, Vice President Sales and Chief Sales Officer of TTTech North America. "We are pleased with the opportunity to support advanced system architectures at Sikorsky Aircraft by providing first-class products and integration with leading open and industry standards."

TTEthernet provides a set of time-triggered services implemented on top of standard IEEE 802.3 Ethernet. Those services are designed to enable design of synchronous, highly dependable embedded computing and networking, capable of tolerating multiple faults. With TTEthernet, robustly partitioned multimedia data streams, critical control data and standard LAN messages can operate in one network without congestion or unintended interactions.
