    Abstract

    THE success of high-speed civil transport aircraft depends on the minimization of its environmental impact. Foremost among these is the aircraft community noise due to takeoff and landing. In addition to jet noise, forward-propagated engine fan noise is a significant component of the overall noise. The noise radiation directivity pattern is influenced by the design of the inlet. This is especially13; true for supersonic inlets where features such as translating centerbody, support struts, and auxiliary doors are contributing factors.
