ABSTRACT:
A pod for mounting a turbofan jet propulsion engine on a strut is constructed so that a common cowl and portions of the fan air duct and turbine exhaust duct can accomodate a plurality of different turbofan engines that have substantially the same thrust rating but have variations in structural dimensions. The portions of the pod common to all such engines include an annular cowl, an inlet throat that merges into the forward end of the cowl to form an inlet highlight, a rearward portion of the outer fan duct wall, a rearward portion of the inner fan duct wall and a turbine nozzle. The common portions of the pod structure are designed about a common datum plane orthogonally oriented relative to the pod center line. The rear face of the turbine casing of each of the turbofan jet propulsion engines is positioned in this datum plane when mounted in the pod. An annular inlet adapter forms an inlet wall that couples the rearward edge of the inlet throat to the forward, peripheral portion of the engine fan casing. Outer and inner fan duct wall adapters couple the common outer and inner portions of the fan duct walls to the engine fan casing at the datum plane. A fan nozzle adapter ring is attached to the rear portion of the cowl and the outer fan duct wall to provide an appropriately dimensioned fan nozzle exit opening. The turbine outlet of at least one of the engines can be coupled directly to the common nozzle of the pod. An annular adapter ring is coupled between the forward edge of the common nozzle and the rearward face of the turbine engine outlet on those engines having a lesser longitudinal dimension.
