A failsafe engine mount (19) that includes a first link (45), a second link (47), a third link (53), four upper connection locations (39a), (39b), (39c), (39d) on an upper fitting (31), and four lower connection locations (75a), (75b), (75c), (75d) on a clevis strip (73) of an engine casing (71), is
A failsafe engine mount (19) that includes a first link (45), a second link (47), a third link (53), four upper connection locations (39a), (39b), (39c), (39d) on an upper fitting (31), and four lower connection locations (75a), (75b), (75c), (75d) on a clevis strip (73) of an engine casing (71), is disclosed. The first link (45) connects the first upper connection location (39a) with the first lower connection location (75a). The second link (47) has a first arm (49) that connects the second lower connection location (75b) with the second upper connection location (39b). The second link (47) further includes a second arm (51) that connects the second upper connection location (39b) with the third lower connection location (75c). The third link (53) has a first arm (55) that connects the third upper connection location (39c) with the fourth upper connection location (39d). The third link (53) further includes a second arm (57) arranged to connect the fourth upper connection location (39d) with the fourth lower connection location (75d). The first arm (55) of the third link (53) carries loads during a failure of the second link (47). In an alternative embodiment, the third link includes a peg (155) instead of a first arm. The peg inserts into a hole (159) in the upper fitting. During normal operations, the peg does not contact the hole surfaces. In either embodiment under normal operating conditions, the links work together to carry the vertical and horizontal/torsion loads of the engine. During a failed link operation, the remaining links work together to carry all loads.
