  2. 1. Experimental Aerothermal Study on Internal Jet Engine Structures

    Author : Isak Jonsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intermediate Compressor Duct; Aerothermal; multi-hole probe; Turbine Rear Structure; transition; experimental; IR-thermography;

    Abstract : For commercial aviation, one potential gain in efficiency can be found in the jet engine auxiliary modules, such as internal jet engine components. These components have historically largely been overlooked, prioritising units such as turbines or compressors. READ MORE

    Abstract : In commercial aviation, efficiency improvements may be gained by aerodynamic optimisation of its structural components, such as the intermediate compressor duct (ICD) and the turbine rear structure (TRS). These components have frequently been overlooked in favour of compressor and turbine module optimisation. READ MORE

  5. 3. Multimethod aerodynamic research of engine-realistic turbine rear structures

    Author : Valentin Vikhorev; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particle image velocimetry; vane lean; pressure taps; enginerealistic; engine-mount recess; European Union EU ; hot-wire anemometry; outlet guide vanes; oil-film visualization; multi-hole probe; turbine exhaust case; bump; turbine rear frame; computational fluid dynamics.; Clean Sky 2; experimental multimethod approach; Horizon 2020; EATEEM; turbine rear structure; low-pressure turbine;

    Abstract : Despite the significant advancements in aircraft engine technology over the past years, the aerodynamics of engine-realistic turbine rear structures (TRS) remain largely unexplored. The TRS, a structural and aerodynamic component situated downstream of the low-pressure turbine (LPT), plays a pivotal role in engine aerodynamic performance, deswirling the LPT flow to maximize the engine thrust.
