TANGENTIAL LINK SWASHPLATE CENTERING MEMBER

摘要

Links (48-50) tangential to the rotorshaft (30) and connected to the inner swashplate ring (38) center the swashplate and restrain it from rotating (in the case of a stationary inner ring) by attachment to gearbox lugs (34-36), or drive it in unison with the rotorshaft (in the case of a rotating inner ring) by attachment to rotorshaft flanges. Spherical (rod-end) bearings (52-54, 56-58) so that the links can accommodate collective and cyclic swashplate attitude changes by moving out of plane. Links (70-72) tangential to the outer swashplate ring (64) and connected thereto and to the airframe (74) perform a similar function in restraining, centering and allowing for collective/cyclic movement of a stationary outer swashplate ring.
