Abstract: Additive manufacturing (AM) methods such as laser powder bed fusion (LPBF) are particularly attractive methods for manufacturing aero-engine burners as they allow for a complex design with well-tailored features at reasonable ...

Abstract: A numerical procedure is presented for the scaling of lean aeronautical gas turbine combustors to different thrust classes. The procedure considers multiple operating points and aims for a self-similar flow field with ...

Abstract: Green hydrogen produced by electrolysis offers a high potential for reducing CO2 emissions and thus represents a promising approach for the decarbonization of aviation. However, propulsion systems based on direct hydrogen ...

Abstract: Ceramic matrix composites (CMC) offer the potential of increased service temperatures and are thus an interesting alternative to conventional combustor alloys. Tubular combustor liner demonstrators made of an oxide/oxide ...

Abstract: The purpose of this paper is to present a multidisciplinary predesign process and its application to three aero-engine models. First, a twin spool mixed flow turbofan engine model is created for validation purposes. The ...

Abstract: Abstract. Developing low-emission aero-engines presents a critical step in meeting near-term climate goals. A particular challenge is accurate soot predictions with computational fluid dynamics (CFD), where the integration ...

Abstract: Abstract. Increasing aero-engine turbine inlet temperatures and stagnating operational limits of nickel-based superalloys creates the need for new materials and cooling technologies. Ceramic matrix composites (CMCs) can ...

Abstract: A numerical investigation is conducted to shed light on the reasons leading to different flame configurations in gas turbine (GT) combustion chambers of aeronautical interest. Large eddy simulations (LES) with a flamelet-based ...
