<p>A semi -levered landing gear (10) is provided that includes a shock strut (12), a truck beam (18) pivotally connected to the shock strut and a semi -levered landing gear mechanism including at least three links (24, 30a, 30b) configured to angularly orient the truck beam and a truck pitch actuation system (40) operatively connected to at least one of the three links. The landing gear mechanism may be configured to cooperate with an extension of a shock strut by positioning the truck pitch actuator in a retracted position, thereby positioning a forward end of the truck beam in a raised position relative to the aft end of the truck beam. The landing gear mechanism may also be configured to cooperate with a retraction of the shock strut into the wheel well by extending the truck pitch actuator to position a forward end (18a) of the truck beam in a lower position relative to the aft end (18b) of the truck beam.</p> |
