Mounting structure for nacelle inner structure

An assembly for an aircraft propulsion system, comprising:

• a pylon structure extending axially along an axis;
• a nacelle inner barrel including a first inner barrel section and a second inner barrel section, the first inner barrel section disposed to a first side of the pylon structure, the second inner barrel section disposed to a second side of the pylon structure that is circumferentially opposite to the first side of the pylon structure, and the first inner barrel section and the second inner barrel section each extending axially along and circumferentially about the axis;
• a nacelle outer structure extending axially along and circumferentially about the nacelle inner barrel;
• a bypass flowpath extending radially between and formed by the nacelle inner barrel and the nacelle outer structure;
• a bifurcation projecting radially out from the nacelle inner barrel across the bypass flowpath to the nacelle outer structure and circumferentially bifurcating the bypass flowpath, the bifurcation radially and axially covering the pylon structure, and the bifurcation including a first bifurcation section and a second bifurcation section;
• and
• a mounting yoke pivotally attached to the pylon structure by a yoke pivot connection at a radial outer end of the mounting yoke, the first bifurcation section and the second bifurcation section attached to circumferentially opposing sides of the mounting yoke;
• a first yoke-to-inner barrel hinge fixedly attached to the first inner barrel section and movably coupled to the mounting yoke at a radial inner end of the mounting yoke;
• and
• a second yoke-to-inner barrel hinge fixedly attached to the second inner barrel section and movably coupled to the mounting yoke at the radial inner end of the mounting yoke;
• wherein the mounting yoke, the first inner barrel section and the second inner barrel section are operable to collectively pivot together about the yoke pivot connection.
