摘要： An individual pitch control device for the blades (7) of a rotor of a rotor craft employing respective rotating linear jacks (29) for controlling the pitch of the rotor blades. The linear jacks are implanted in a rotating support (25) which is driven in rotation with the rotor. The jacks (29) include rods (31) which are connected via additional rods (33) to drive pitch control levers (24) for each respective blade. The jacks (29) are linear, electrohydraulic, dual-action jacks having at least one body, and are supplied by control servovalves (36) which are also mounted in a rotating reference system. The servovalves (36) are supplied from a hydraulic circuit in a fixed reference system positioned on the rotor craft, having at least one hydraulic collector (27) which is at least partially rotating.

摘要： The resilient return strut is of the elastic-hydraulic type with incorporated linear damping by throttling a high-viscosity fluid, and comprises a damper (1) mounted between two return springs (2, 3) in elastomer-based sleeves (17, 18), undergoing a shearing action and sealing the chambers (34, 35) set off within the body of the damper (12) by a transverse wall (10) which marks off a permanent throttling passage around a central brace (23). Limiting valves equipped with spring-leaves (45) sealing the holes (40) bored in the wall (10) increase the throttling section. A compressed-air system (52), mounted in a spring (2), compensates for thermal expansion of the fluid. The device is used with helicopter rotors.

摘要： The device comprises anti-cone stops projecting outwards from a common ring that can rotate about the rotor axis on the top face of the hub and flyweights are each individually joined to the ring for driving the latter in rotation from the "ground" position, in which each anti-cone stop is facing an upper bearing shoe of the corresponding blade, to the "flight" position, in which the anti-cone stops are retracted, returning them to the "ground" position.
