A pitch trimmer assembly for an aircraft landing gear having a damping element arranged to be connected between a first and a second element of an aircraft landing gear and arranged to exert a first damping force when in a first state and a second damping force in a second state, the damping element being switchable between the first and second states in dependence on the relative positions of the first and second landing gear elements.

Aircraft landing gear pitch trimmer actuator with variable damping

An actuator arranged to be movable between an extended condition and a compressed condition and being biased to an intermediate condition between and distinct from the extended condition and the compressed condition. The actuator includes a damping device arranged to define the damping coefficient of the actuator. The damping device is arranged to provide a relatively low damping coefficient when the actuator is in a first condition distinct from the intermediate condition, and a relatively high damping coefficient when the actuator is in a second condition, the second condition being distinct from the first condition and being equal or adjacent to the intermediate condition

A damper for an airplane landing gear leg comprises a main strut () and a rod piston () co-operating with the strut () to define a main chamber () and annular chamber () for hydraulic fluid, and presenting internally two adjacent chambers () that are isolated from each other by a separator piston (). The damper () further comprises a first secondary strut () telescopically Slidable on the above-mentioned rod piston (), and a second secondary strut () telescopically slidable on the other end of the first secondary strut (). The two second annular chambers () as defined in this way are respectively connected to associated control circuits thus enabling the total length of the damper to be shortened or lengthened respectively for the purpose of causing the landing gear to contract or to be extended.
