Project description DEENESFRITPL Unsteady aerodynamics, aeroacoustics and aeroelasticity of jet engines Engine technology in aircraft has continuously evolved over the last decades – the reduction in fuel burn has been a driving force behind this progress. Growing evidence suggests that unsteady aerodynamics, aeroacoustics and aeroelasticity are limiting the potential of jet engine technologies. The EU-funded CATANA project is dedicated to shedding further insight into the nature of these physical instabilities. The project will carry out experiments that will allow synchronous measurements of aerodynamic, structure-dynamic and acoustic phenomena. Studies on the structural mistuning and intake geometry will allow researchers to quantify the sensitivity of the instability mechanisms. The participating institutes will challenge existing knowledge in the field, and provide a reference point for further studies on efficient jet engines. Show the project objective Hide the project objective Objective There is increasing evidence that today’s turbojet technology is limited by instabilities arising from non-linear coupling between aerodynamic, aeroelastic and aeroacoustic phenomena. These multi-physical processes are going to become even more important in future architectures, which utilize Ultra-High-Bypass Ratio and lightweight composite fan designs to reduce greenhouse gas emissions and noise. However, enormous knowledge gaps currently exist concerning these processes and the resulting stability boundaries. To fill these gaps, and to promote the development of efficient and quiet concepts, a comprehensive research programme will be carried out in Project CATANA. The programme will provide an open-test-case fan stage and employ unprecedented instrumentation to perform extensive investigations into the nature of multi-physical instabilities. The carbon-fibre fan stage is currently being developed at Ecole Centrale de Lyon and will be aerodynamically and structurally representative of near future low-speed fans. Multi-physical experiments are planned which allow transient investigations with synchronous measurements of aerodynamic, structure-dynamic and acoustic phenomena. The research concept combines complementary measurement systems and enables the detection of interactive mechanisms where individual systems are insufficient. To improve the coherence of the aeroelastic results, a study on structural mistuning and intake geometry will be carried out to understand and quantify the sensitivity of occurring instability mechanisms. The database will be completed by a detailed structural analysis of the stage providing modal characteristics of the rotor blades, including structural damping under rotation.The participating laboratories of Ecole Centrale de Lyon and the Von Karman Institute for Fluid Dynamics have the experience to challenge the demanding research initiative with the ambition to provide a reference benchmark for the European research community.
