Abstract
A semi-levered landing gear is provided that includes a shock strut, a truck beam pivotally connected to the shock strut and a semi-levered landing gear mechanism including at least three links configured to angularly orient the truck beam and a truck pitch actuation system 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 of the truck beam in a lower position relative to the aft end of the truck beam.
