HEATTOP (acronym for "Accurate High-temperature Engine Aero-Thermal measurements for gas Turbine life Optimization, Performance and condition monitoring") is a project funded by the European Community as part of the Sixth Framework Programme (FP6).

The project targets the development and improvement of instrumentation to measure pressure, temperature (gas temperature, surface temperature, blade temperature), flow and tip clearance in gas turbines. The sensors studied in HEATTOP include both devices to be used during routine operation and in the development phase of the engine: more rugged and accurate sensors allow gas turbine manufacturers to measure more reliably physical parameters in region of the engine which are currently not instrumented and at the same time can provide crucial information currently unavailable for the design of improved new engines.

HEATTOP has originated from the need of measurement capability improvement underlined in the Lab Gap Matrix, a study which was undertaken few years ago from the EVI-GTI (European Virtual Institute for Gas Turbine Instrumentation). Further details on the Lab Gap Matrix can be found at the following web address:
