Claims20
A lubricant system for a gear assembly of an aircraft including an engine, the lubricant system comprising:
- a main lubricant conduit and an emergency lubricant conduit joined with a valve, and further wherein the valve defines a closed position disposing lubricant through the emergency lubricant conduit when the engine is at rest, and wherein the valve defines an open position disposing lubricant through the main lubricant conduit when the engine is in operation.
A method for operating a lubricant system for a gear assembly of an aircraft, wherein the aircraft comprises one or more engines, the method comprising:
- supplying a pressurized flow of lubricant to the lubricant system;
- determining whether a valve disposed at a main lubricant conduit and an emergency lubricant conduit indicates an open position when the engine is at rest, wherein the open position indicates a failure of the valve enabling flow of lubricant from the emergency lubricant conduit to the gear assembly;
- and
- generating a signal indicating the open position of the valve when the engine is at rest.
