ABSTRACT:
An integrated history recorder for a gas turbine engine includes a number of integrally controlled displays which together provide a comprehensive record of accumulated engine life. The recorder is adapted to interface with an engine contained transducer assembly.
Displays indicative of the following parameters are provided: the number of engine starts, engine running time, the number of engine turbine over-temperature occurrences, turbine time-temperature index, and a manually resettable flag which sets on occurrence of a turbine over-temperature event. These integrally controlled displays provide a comprehensive indication of the cumulative duty performed by the gas turbine engine.
