Abstract
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.
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.
Originality/value
Both the duct loss and flow distortion can be simultaneously reduced by significant amounts.
