Aerospace actuator stroke limiting device

An aerospace actuator, comprising:

• an actuator housing comprising a first exterior surface and first exterior threading disposed on the first exterior surface;
• a second part comprising a retraction-limiting surface, a first interior surface, first interior threading disposed on the first interior surface, a second exterior surface and second exterior threading disposed on the second exterior surface, both the second exterior surface and the second exterior threading being outside of both the first interior surface and the first interior threading;
• a third part comprising an extension-limiting surface, a second interior surface and second interior threading disposed on the second interior surface;
• a piston movable within the actuator housing between a retraction-limited position where the piston impinges against the retraction-limiting surface and an extension-limited position where the piston impinges against the extension-limiting surface;
• and
• a stroke limiting device comprising:
• a first automatic adjustable engagement unit comprising an engagement of the first exterior threading and the first interior threading to which a first electromechanical motor is coupled to automatically adjust a first distance between the actuator housing and the retraction-limiting surface;
• and
• a second automatic adjustable engagement unit comprising an engagement of the second exterior threading and the second interior threading to which a second electromechanical motor is coupled to automatically adjust a second distance between the extension-limiting surface and the retraction-limiting,
• wherein:
• an adjustment of the first distance by the first automatic adjustable engagement unit is independent of an adjustment of the second distance by the second automatic adjustable engagement unit, and
• the adjustment of the second distance by the second adjustable engagement unit is independent of the adjustment of the first distance by the first adjustable engagement unit.
