ABSTRACT:
A one piece inner cowling for a bifurcated fan duct is provided having an integral core cowl and radially extending bifurcation sidewalls for use in a bifurcated fan bypass duct of a turbofan engine. In the preferred embodiment the sidewalls extend substantially to the end of the fan duct and the core cowl extends substantially between the fan and turbine frames. The cowling is preferably made of a composite material, preferably graphite/PMR-15 and provisions are made for mechanically attaching the sidewalls to an outer cowl. The inner cowling and outer cowl assembly form one half of a bifurcated fan duct assembly for being pivotally attached to a turbofan mounting pylon and includes suitable latching apparatus for accessing the core engine by pivotally opening the mirror image bifurcated fan duct assemblies on either side of the engine.
