Abstract

A system and method combines integrated system health usage monitoring and flight tracking of a helicopter, and transmits the information to monitoring sites for managing flight operations in real time, thereby providing the functionality of both system health and flight tracking and reducing weight related constraints faced by helicopters. With enhanced availability of system health data, vital information for maintenance and flight position data-stream, operations, flight dispatch and maintenance can plan for required services more efficiently.

Claims

1. A method of monitoring health and itinerary of a helicopter comprising:

monitoring the health of a rotor system on the helicopter via a processor;

tracking the location of the aircraft via the processor;

correlating the health and location via the processor;

determining if an environment of the location has an effect on the health beyond a threshold;

comparing current health patterns versus typical health patterns;

creating indicators related to the health, environment, and the comparison of the current health patterns versus typical health patterns; and

transmitting the indicators and location to a managing site via a data link unit for purpose of potentially modifying flight operation of the helicopter.

2. The method of claim 1 further comprising:

translating data acquired from the monitoring step into one of a plurality of condition indicators via the processor; and

transmitting the data to the managing site via the data link unit.

3. The method of claim 1 wherein the monitoring, tracking, and correlating are accomplished by a single system architecture within the processor.

4. The method of claim 1 further comprising:

transmitting via the data link unit the correlated health and location when a threshold is exceeded.

5. The method of claim 1 further comprising:

translating the correlated health and location periodically via the processor.

6. The method of claim 1 further comprising:

calculating a remaining useful life of the rotor system based on parametric data, condition indicators, flight conditions, and operation data via the processor; and

transmitting the useful life to the managing site via the data link unit.

7. The method of claim 6 wherein calculating comprises:

calculating a mean time between failures via the processor.

8. The method of claim 1 further comprising:

determining a typical usage of the rotor system for comparison with the monitored health of the rotor system via the processor.

9. The method of claim 1 wherein the monitoring the health comprises:

monitoring the vibration of the rotor system via the processor.

10. The method of claim 1 wherein monitoring the health further comprises monitoring an engine and a turbine.

11. The method of claim 1 further comprising:

determining the remaining route of the helicopter via the processor; and

the correlating step considers the remaining route.

12. A method of monitoring health and itinerary of a helicopter, comprising:

determining the health of a rotor system of the helicopter via a processor;

determining current flight parameters of the helicopter via the processor;

determining if an environment of the location has an effect on the health beyond a threshold;

comparing current health patterns versus typical health patterns;

correlating the health and the current flight parameters via the processor;

creating indicators related to the health, environment, and the comparison of the current health patterns versus typical health patterns; and

transmitting the correlated health and current flight parameters for analysis by a monitoring station via a data link unit for purpose of potentially modifying flight operation of the helicopter.

13. A system for monitoring the health, and the location, of a helicopter, the system comprising:

a monitoring device configured to;

monitor the health of a rotor system on the helicopter;

determine the location of the helicopter;

correlate the health and location;

determine if an environment of the location has an effect on the health beyond a threshold;

compare current health patterns versus typical health patterns; and

create indicators related to the health, environment, and the comparison of the current health patterns versus typical health patterns; and

a data link coupled to the monitoring system and configured to;

transmit the correlated health and location to a ground site for purpose of potentially modifying flight operation of the helicopter.

14. The system of claim 13 wherein:

the monitoring device is further configured to translate data acquired from the monitoring step into one of a plurality of condition indicators; and

the data link is further configured to transmit the data to the managing site.

15. The system of claim 13 wherein the monitoring device comprises single system architecture by consolidating health monitoring and flight tracking.

16. The system of claim 13 wherein:

the monitoring device is further configured to calculate a remaining useful life of the rotor system; and

the data link is further configured to transmit the useful life to the managing site.

17. The system of claim 13 wherein the monitoring device is further configured to:

monitor the performance of the engine.

18. The system of claim 13 wherein the system comprises an engine and a transmission.

19. The system of claim 13 wherein the monitoring device is further configured to:

determine the remaining route of the helicopter; and

consider the remaining route.

20. The system of claim 13 wherein the monitoring device is further configured to:

monitor systems operational margins of the helicopter including available engine power.
