Health awareness rotorcraft

GE’s Health and Usage Monitoring System (HUMS) unlocks operational data insights to detect rotorcraft safety events and reduce ongoing maintenance lifecycle costs.
Failure to manage vibrations caused by out of balance or off-track rotors will eventually lead to long-term damage to airframes, avionics, and drivetrain components. Requires frequent need to apply track and balance adjustments to ensure vibrations remain within acceptable tolerances.
GE’s HUMS helps reduce unplanned maintenance from excess vibration,capturing data on every flight so you can proactively know when you need to make rotor adjustments.
Immediate ROI on rotor track and balance by reducing the need for additional test flights.
Incorrectly identifying failed components and systems leads to increased maintenance costs and reduced mission availability of the rotorcraft. No Fault Found (NFF) leads to increased repair time and maintenance efforts.
GE’s Health Awareness System (HAS) software product that combines the best of predictive analytics and configurability from commercial fixed wing solutions with rotorcraft health and operational flight data. GE HAS manages the health of the entire rotorcraft integrated within existing or new sub systems including Health and Usage Monitoring System (HUMS), network switches and/or other line replaceable units (LRUs).
Root cause analysis of reported failures can eliminate excessive inventory of spare parts and systems. Reduces unnecessary removal, inspection and test of components driving down maintenance costs and time. Data driven analytics leads to “right fix at the right time” increasing rotorcraft availability.
Rotorcraft crew reports significant parament exceedance overload. This overload can cause damage to the drivetrain and could require the rotorcraft be pulled out of service and inspected.
GE HUMS automatically and continuously records operational flight exceedance parameters set to OEM derived limits and determines the magnitude of the overload exceedance immediately. Data from before, during and after the event is analyzed to visualize trends, manage severity levels and time of duration of the exceedance.
Manage costs and implement “right fix at the right time” by using mission critical recorded flight data to determine the correct maintenance actions. Eliminate ambiguous reports and add additional layer of protection to the rotorcraft and fleet by accurately recording and reporting exceedances from the member systems.
Incorrectly torqued bolts or faulty manufactured gears/bearing may cause excessive vibration, loss of power requiring the replacement of expensive drivetrain parts.
GE HUMS can provide early warning of these types of problems before long lasting damage may occur to your mission critical systems. The maintainers are provided easy to understand condition indicators that make it simple to take corrective action. Analyses have proven that the GE HUMS system can correctly isolates faults, detects events and prevents subsequent damage. The technology can pinpoint the exact bearing component type raceway or roller that is beginning to fail.
Early identification of problems with mission critical systems such as drive trains provides operators with timely options. Eliminating unplanned maintenance reduces operational costs and can help minimize safety of flight situations from component failure.
