RMCI Canada is bringing the Expandable Rotorcraft Diagnostic System (XRDS™) to the commercial rotary industry. XRDS will meet the need for a fully integrated, light weight, low power, low cost, single system solution enabling both comprehensive rotorcraft health management and flight operations quality assurance  (FOQA) for light and medium helicopters. XRDS combines the roles of vibration health monitoring (VHM), usage monitoring, flight data monitoring (FDM), and rotor smoothing into a single system. Using XRDS, fleet operators of any size will be able to monitor gearboxes, bearings, shafts, engines, and rotor systems. XRDS is able to detect multiple fault conditions, including rotating component corrosion, bearing defects, gear tooth defects, shaft imbalance, shaft misalignment, manufacturing defects, and installation errors. XRDS provides helicopter operators with advanced mechanical diagnostics and a comprehensive rotor smoothing solution at an affordable price point.
