Computational design of S-Duct intakes for distributed propulsion

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.
