Korry Aircraft Data Concentration and Processing Solutions
DCU Capabilities
Esterline is an industry leader in developing aircraft data collection, conversion, and routing solutions, usually referred to as DCUs (data concentrator units). Our Korry DCUs deliver the technology you need to implement rugged, scalable, fault-tolerant data networks, with:
Proven airborne reliability
Versatile I/O and databus management
Compact, low-weight designs
Self calibration, self testing
DCUs collect discrete inputs, analog signals, and digital data from sensors and equipment throughout the aircraft, then convert them to digital format for streaming over the databus of the flight-control or aircraft-management system (typically ARINC 429, ARINC 664/AFDX, CAN bus, Ethernet, MIL-STD-1553, RS-422, RS-485).
Main advantages include reduced cabling and minimal signal interference, as well as improved robustness and survivability, through distributed redundancy and the elimination of single points of failure.
We optimize DCU reliability, weight, and size by engineering all our units to systematically reduce component count and connections. We implement state-of-the-art electronics technologies, including:
Embedded passives
System on a chip
Configurable I/O
FPGA circuit integration
Our electronics are so compact that the final form factor is driven by customer requirements for the number of I/O pinouts and associated connectors.
With our depth of expertise in electronics design, software, and mechanical engineering, as well as manufacturing and testing, we are able to deliver solutions perfectly suited to your platform requirements.
