    Connect to safety
    HUMS is an end-to-end health awareness system monitoring rotorcraft systems data like:-
    • Airframe
    • Engine and drivetrain vibration
    • Exceedances
    • Chip detections
    • Balance, HUMS uses GE proprietary algorithms that can be configured by OEM’soperators to enable preventive repairs instead of major maintenance actions.

    Health and Usage Monitoring System



    Enables reduction in cost of rotor track and balance activities

    Incident
    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.
    Response
    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.
    Value
    Immediate ROI on rotor track and balance by reducing the need for additional test flights.

    Reducing No Fault Found (NFF) for Rotorcraft

    Incident
    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.
    Response
    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).
    Value
    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.

    Accurately monitor Exceedance Based Events to perform required maintenance and ensure air worthiness limits.

    Incident
    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.
    Response
    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.
    Value
    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.

    Early detection of critical component failure improves safety and prevents further damage and costs.

    Incident
    Incorrectly torqued bolts or faulty manufactured gears/bearing may cause excessive vibration, loss of power requiring the replacement of expensive drivetrain parts.
    Response
    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.
    Value
    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.
