Abstract

Validated computational methods exist which can predict sound propagation and absorption in turbofan intake and bypass ducts. In this article, the practicability of embedding such methods within automated and semi-automated liner optimisation schemes for realistic nacelle geometries, liner definitions and noise source spectra is investigated. Two different strategies are used to demonstrate the feasibility of applying such an approach to intake liner optimisation.
