(2023) Thrust/drag decomposition using partial pressure fields. In: 57th 3AF Applied Aerodynamics Conference AERO2023, 29-31 March 2023, Bordeaux, Francehttps://dspace.lib.cranfield.ac.uk/handle/1826/19663Presented at: 57th 3AF Applied Aerodynamics Conference AERO2023, 29-31 March 2023, Bordeaux, FranceThe accurate prediction of aircraft performance requires a robust definition of thrust/drag accounting. Traditional nacelle-pylon configurations have been treated as separate entities which are combined linearly; however, this is not feasible for embedded propulsion systems which have a higher degree of interaction than traditional designs. With the apparent shift to embedded propulsion systems in the N+3 generation of aircraft, of which boundary layer ingestion technology is a driving factor, improving our understanding of propulsion system interactions with an air-frame has never been more important. Since many of these interactions occur close to the body, a near-field decomposition method, partial pressure fields, is employed in CFD to provide insight as to the interactive aerodynamics of an embedded propulsion system.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Conference paper
