Product overview

The United Aircraft Multiple Redundant Flight Control Computer combines a self-monitoring processor with a high-speed serial LVDS backplane architecture. Its processor reaches 300 MHz and includes L1 cache, while the backplane provides 100 MB bandwidth. Resource allocation provides multiple redundancy across the CPU, interfaces and power supply. A main/standby operating mode supports fault tolerance and continued operation when a failure occurs. The design combines high safety and reliability with reduced size and abundant interfaces.

An embedded ultra-large-capacity data storage unit and file management system provide onboard storage capabilities. The computer supports PUBIT, IFBIT and GBIT with high test coverage. Applications include converting a 700 kg manned helicopter into an unmanned platform, research and development of a 500 kg coaxial unmanned helicopter, and use in a 3-ton UAV platform.
