Computational design of S-Duct intakes for distributed propulsion

– The purpose of this paper is to identify efficient methods and tools for the design of distributed propulsion architectures.

– Multi-objective computational aerodynamic design optimisation of an S-Duct shape.

– Both duct pressure loss and flow distortion through such a duct can be reduced by wall-curvature changes.

– Initial simplified study requires higher fidelity computational fluid dynamics & design sensitivity follow-up.

– Shape optimisation of an S-Duct intake can improve intake efficiency and reduce the risk of engine-intake compatibility problems.

– Potential to advance lower emissions impact from distributed propulsion aircraft.

– Both the duct loss and flow distortion can be simultaneously reduced by significant amounts.
