ABSTRACT:
A retractable wing-mounted landing gear (10) for a heavy airplane with an aft center of gravity includes a trunnion (12), an aftly-cantilevered strut member (26), a ground-contacting wheel assembly (44, 46), and a folding drag brace (30). The trunnion (12) is operably mounted to the wing (14) for pivotal movement about a substantially forward and aft axis of rotation. The trunnion (12) is rotatable to cause substantially lateral movement of the gear (10) between in-use and stored positions. The strut member (26) has upper and lower ends, the upper end being pivotally connected (28) to the trunnion (12) for relative forward and aft movement thereto. The pivotal connection (28) has an axis of rotation substantially perpendicular to that of the trunnion (12). The ground-contacting wheel assembly (44, 46) is operably connected to the lower end (54) of the strut member (26). The folding drag brace (30) extends between the lower end (54) of the strut member (26) and a location on the aircraft spaced forwardly from the strut member (26). The folding drag brace (30) is movable between an in-use stabilizing position and a stowed position in which the drag brace (30) folds to permit relative forward and aft movement of the strut member (26). The strut member (26) is cantilevered aftly relative to the trunnion (12) when the gear (10) is in the in-use position. The strut member (26) pivots relatively forwardly for lateral, inboard retraction of the gear (10) to the stowed position.
