Razorback-300 Avionics Single-Board Computer Turbine Engine Monitoring System

The Razorback-300 (RB-300) avionics single-board computer turbine engine monitoring system is an extremely compact and low-power, aerospace grade x86 compatible computer. Developed by Southwest Research Institute (SwRI), the RB-300 computes real-time engine parameters with simultaneous data capture. The RB-300 modernizes legacy aircraft systems while remaining compatible with previous generation support equipment.
