Abstract

© Emerald Group Publishing Limited. Purpose: The purpose of this paper is to identify efficient methods and tools for the design of distributed propulsion architectures. Design/methodology/approach: Multi-objective computational aerodynamic design optimisation of an S-Duct shape. Findings: Both duct pressure loss and flow distortion through such a duct can be reduced by wall-curvature changes. Research limitations/implications: Initial simplified study requires higher fidelity computational fluid dynamics & design sensitivity follow-up. Originality/value: Both the duct loss and flow distortion can be simultaneously reduced by significant amounts. Practical implications: Shape optimisation of an S-Duct intake can improve intake efficiency and reduce the risk of engine-intake compatibility problems. Social implications: Potential to advance lower emissions impact from distributed propulsion aircraft.
