ABSTRACT:
The inlet of a turbofan jet propulsion engine is coupled to the engine fan casing via a unique uniflange coupling assembly. One of the inlet and casing components carries a radial flange while the other of the components carries a pair of radial flanges each spaced on opposite sides of the flange carried by the first component. A pair of toroidally shaped members are positioned respectively between the two pairs of spaced opposing abutment surfaces thus formed by the three flanges. Preferably the members are hollow, have flexible but substantially inelastic walls, and are filled with a fluid. These members allow the two components to angulate relative to each other while allowing loads to be transferred from the first component to the second component only in an axial direction. Other loads are transferred to the engine mounting structure through other linkage.
