The propagation of acoustic waves along a duct of elliptic cross-section, the eccentricity of which varies slowly along the axis, is considered as a model of the unsteady #ow inside a realistic aeroengine nacelle. This is a development of recent work on a circular duct by Rienstra. The acoustic "eld
