Aircraft gas turbine engine sideways mount

An aircraft engine assembly for an aircraft;

• a gas turbine engine having a gas generator operably disposed to flow motive fluid to a power turbine which at least in part is drivingly connected to a fan section of said engine,
• a mount assembly for mounting said engine sideways to the aircraft by an engine structure which rotatably supports an engine rotor assembly about an engine centerline,
• said mount assembly further comprising a pivotable engine suspension for mounting said engine structure sideways from the aircraft and which permits at least limited axial movement of the engine,
• said pivotable engine suspension including a pivotable forward support mount pivotably connected to a forward engine frame of said engine structure and a pivotable aft support mount connected to an aft engine frame of said engine structure,
• a thrust mount disposed between said forward and aft support mounts, said thrust mount having a thrust bar means for reacting out substantially all thrust load forces from the engine to the aircraft and forming a four bar linkage,
• said linkage including first, second, third, and fourth bars wherein said first bar comprises said thrust bar means and is pivotably connected at a first axial end of said first bar to an engine mid-frame of said engine structure and is pivotably joined to the aircraft by a second axial end of said first bar at an axial position on the aircraft between said forward and aft support mounts,
• said fourth bar is disposed between first and third bars and said fourth bar fixedly mounted to the aircraft,
• said second bar comprises an axially extending portion of said engine structure and which extends from said mid-frame to said aft frame and said second bar is pivotably connected to a first end of said third bar wherein said third bar is a support means of one of said support mounts,
• said thrust bar has a line of action which intersects the engine centerline in a support mount plane through which said forward support mount mounts the engine and which is generally perpendicular the engine centerline, and
• said thrust bar comprises a pair of spaced apart thrust links which are vertically spaced apart at their respective pivotal joints to the aircraft and circumferentially spaced apart at their respective pivotal joints to said mid-frame.
