Fan casing (32) of turbo fan jet propulsion engine (20) is mounted to a forward portion of a wing strut (24) by a forward hanger assembly (50). The rearward portion of the core assembly (26) of engine (20) is suspended from wing strut (24) by a rearward hanger assembly (80). A yoke assembly (100) extends forwardly from rear hanger assembly (80) to interconnect with the forward portion of the engine core assembly (26) to restrain against axial movement thereof. Fan casing link (66) extends diagonally upwardly and rearwardly from fan casing (32) to intersect with wing strut (24) at a location rearwardly from the location at which the forward hanger assembly (50) is secured to the wing strut. The fan casing link (66) functions to restrain fan casing (42) from axial movement relative to engine core assembly (26) thereby reducing the relative displacement between these sections of engine (20) due to reactive thrust loads acting through the engine (20) and air loads acting upwardly against a leading inlet cowling (40) that extends forwardly of fan casing (32).

A system for securing a jet propulsion engine to an aircraft, the engine having a core assembly, a fan powered by the core assembly and a fan casing enclosing the engine fan, said securing system comprising: first means extending between the fan casing and the aircraft for securing the fan casing against lateral and vertical movement relative to the aircraft; second means for securing the fan casing against pitch movement relative to the aircraft during normal operation of the aircraft, said second securing means comprising substantially rigid fan casing link means oriented generally longitudinally relative to the engine to transmit forces imposed on the fan casing along a vector component extending longitudinally relative to the engine, said fan casing link means connected at one end to the aircraft at a location longitudinally spaced from the location of the connection between the first securing means and the aircraft and connected at the opposite end closely adjacent the location of the connection between the first securing means and the fan casing; and, third means for securing the engine core assembly to the aircraft to retain the engine against lateral, vertical and torsional movement relative to the aircraft, said third securing means includes an elongate thrust yoke disposed generally longitudinally relative to the engine axis of rotation, said thrust yoke having a forward end portion secured to a forward portion of the engine core assembly at locations relative to the diametrical center of the engine axis of rotation toward the circumferential location at which said fan casing link means is connected to the fan casing.
