Cooled Fast-Response Wall Pressure Taps for Combustion Chamber Measurements

Project description

Innovative pressure probes for flame instability control in high-performance gas turbines

Dynamic instabilities are the main roadblock to developing low-emission, lean-burn combustors for next-generation jet engines. The EU-funded FAST TAPS project will develop wall-mounted fast-response pressure taps for combustion chamber measurements. Such an instrumentation should help extend the knowledge on combustion instabilities in realistic engine conditions. FAST TAPS aims to establish a new, complete and robust design methodology for fast-response pressure probes. Project activities will pave the way towards greener and quieter turboprop engines in the 1 800–2 000 shp class for business aviation and short-range regional applications.


FAST TAPS aims at designing, validating and put in operation 8 cooled fast-response wall pressure taps for combustion chamber measurements.

The project is based upon a three steps approach, the three technical work packages of the project, with two distinct iterative design and validation loops.

In the first step, the measurement devices will be designed according to the desired measurement performance (i.e. the required bandwidth), the environmental conditions (high-temperature and high-pressure flow) and the structural and mechanical constraints. The design candidates will undergo an internal experimental and numerical validation process prior to the submission to the topic leader.

In the second step, prototypes will be built according to the final design candidate and tested in engine-representative conditions. The analysis of the results will either provide the final approval for the machining of the final measurement devices or highlight some modifications to be further implemented.

The third step deals with the final manufacturing of the cooled fast-response wall pressure taps and their qualification tests (static and dynamic calibrations).

From a scientific point of view, FAST TAPS targets the definition of a new, complete and robust design methodology for fast-response pressure probes. Such knowledge is doomed to be made available to the scientific community through the FAST TAPS dissemination activities.
