ABSTRACT:
A bellcrank assembly, adapted for mounting on, and actuating, a convergent flap of the exhaust nozzle of a turbojet engine. The unique structure of the assembly, unlike the prior art, transmits radial and bi-directional thrust loads to the flap utilizing low cost stamped and formed sheetmetal components, with the loads being transmitted directly into the skin of the flap. The bellcrank assembly is structured for external mounting on the convergent flap, thereby permitting easy inspection, maintenance and service, without the need to disassemble other nozzle hardware; and, it includes angular contact bearings with cross-corner path arrangement, and bellcrank link arms and a bellcrank actuator arm which actually physically comprise the housing of the bellcrank.
