- The experimental characterisation and 1D correlations developed relate to the design of broadband passive dampers for supressing high frequency thermo-acoustic instabilities within aircraft gas turbine exhaust systems. The results of this work have been embedded within Rolls-Royce low order design codes to directly impact on Rolls-Royce product design. In addition, the experimental methods developed have been applied to evaluate the performance of acoustic dampers within other parts of the gas turbine (e.g., combustion system), for other component types (e.g., fuel injectors) and for validation of numerical methods (UTC Coordinator, Rolls-Royce plc., Bristol)
