Abstract. Various papers on numerical methods for engine-airframe integration are presented. The individual topics considered include: scientific computing environment for the s, overview of prediction of complex turbulent flows, numerical solutions of the compressible Navier-Stokes equations, elements of computational engine/airframe integrations, computational . Advanced aircraft concepts are increasingly reliant on closer coupling of propulsion systems with airframe aerodynamics, or propulsion/airframe integration (PAI), for optimal performance. For instance, several advanced concepts employ fuselage boundary layer ingestion by turbofan engines to achieve a reduction in mission fuel burn.

Since , he is Head of the Transport Aircraft Branch at the Institute of Aerodynamics and Flow Technology, and External professor of the Technical University of Baunschweig (lecturer for configuration aerodynamics). His research fields are high lift aerodynamics engine/airframe integration, CFD and turbulence model validation.   The wind tunnel is still an important pillar for the aerodynamic investigations of engine installation effects, such as the strong aerodynamic interferences between an underwing mounted engine and the wing itself. To consider real engine effects on the aerodynamics in the wind tunnel environment the turbine powered simulator (TPS) technique is one of the widely Cited by: 2.

The increases in C D resulting from the presence of the jet was approximately % for the engine configuration in comparison to the wingbody configuration, for the ultra high bypass ratio engine.

The engine is initially considered in a reference position. Successively, position variations of the engine are performed to analyze the interaction with the supersonic region and shocks on the wing upper Author: Luciana Savoni, Ralf Rudnik.
