Abstract: The present application includes a blade-pitch control system with an indexing swashplate. A swashplate assembly has a non-rotating portion and a rotating portion and an indexing portion of the mast. The swashplate assembly is translatably affixed to the indexing portion. A pitch link connects the rotating portion of the swashplate assembly to each blade. Translation of the swashplate assembly along the indexing portion causes a change in pitch of the blades and a corresponding indexing of the rotating portion of the swashplate assembly relative to the mast, the indexing causing a change in an angular orientation of each pitch link, thus providing for selected pitch-flap coupling between flapping motion of the yoke and pitch motion of the blades.

Abstract: A system and method to change a spring rate of a damper in real time. The damper includes a housing having an inner surface that forms a cavity. An elastomeric material is disposed within the cavity and fixedly attached to the inner surface of the housing. A first chamber is formed by a first end of the elastomeric material and the inner surface of the housing. The method includes restricting movement of the elastomeric material by regulating the pressure within the first chamber, which in turn changes the spring rate of the damper.
