PROBLEM TO BE SOLVED: To provide an apparatus, methods and systems relating to the cost-effective systems that accurately calculate and monitor tip clearances in turbine engines.SOLUTION: A method of calculating the tip clearance during operation of a combustion turbine engine (10) that includes the steps of: measuring a cold tip clearance and a cold shell-to-shell distance; while the combustion turbine engine (10) is operating, measuring an operating parameter and measuring a shell-to-shell distance with a proximity sensor (22); calculating the tip clearance based on the cold tip clearance measurement and the operating parameter measurement; calculating the shell-to-shell distance based on the cold tip clearance measurement and the operating parameter measurement; comparing the shell-to-shell distance measurement of the proximity sensor (22) with the shell-to-shell distance calculation; and calibrating the calculated tip clearance calculation based on the comparison. |
