Title:
APPARATUS AND METHOD FOR DETERMINING GAS TURBINE ENGINE LIFE
Document Type and Number:
WIPO Patent Application WO/1995/018364
Kind Code:
A1
Abstract:
An apparatus and method (10) is provided for determining and recording the life and run values of a gas turbine engine (12). A starter drop out sensor (24) and a turbine inlet temperature sensor (20) delivers a respective drop out and turbine temperature signal. A receiving device (46) receives the signals and advances the life recorder (126) a predetermined amount based on a linear failure prediction curve for each completed turbine engine start in response to the turbine inlet temperature (118) being greater than a set point value and the starter drop out signal being received. The receiving means (46) also delivers a signal to enable advancement of the run recorder (42) in response to the sensed turbine inlet temperature exceeding the set point value. A generating device (89) delivers a signal to advance the life recorder (126) an amount for the sensed turbine temperature based on a turbine life curve (128) having turbine temperature to voltage coordinates.
