The connector system (30) includes a pivoting member (38) pivotally attached to a guide anchor (36) that is moveable secured within a guide track (34). The guide anchor (36) is movably secured between first and second strength walls (58, 62). At least one guide shoulder (70) and the pivoting member
The connector system (30) includes a pivoting member (38) pivotally attached to a guide anchor (36) that is moveable secured within a guide track (34). The guide anchor (36) is movably secured between first and second strength walls (58, 62). At least one guide shoulder (70) and the pivoting member (38) define throughbores (74, 76, 78) that receive a rod (92) of a rod-and-bracket connector (88) to pivotally secure the pivoting member (38), such as a convergent flap (26) of an exhaust nozzle assembly (22). The rod-and-bracket connector (88) utilizes an L-shaped arm (96) to eliminate need for a large thread and lock nut assembly (86) between the strength walls (58, 62) to thereby facilitate use of larger, stronger guide shoulders (70, 72) between the strength walls (58, 62) to maximize strength of the connector system (30) while minimizing its volumetric displacement.
