A folding strut having upper and lower portions (14, 16/62, 64) are connected together by a pivotal joint (18, 66, 68) for folding movement relative to one another upon extension and retraction of the strut. The upper portion (14, 62) of the strut is pivotally mounted to the aircraft frame (52, 80).
A folding strut having upper and lower portions (14, 16/62, 64) are connected together by a pivotal joint (18, 66, 68) for folding movement relative to one another upon extension and retraction of the strut. The upper portion (14, 62) of the strut is pivotally mounted to the aircraft frame (52, 80). A locking brace (42, 44/84, 86) extends between the upper and lower strut portions (14, 16/62, 64) to brace the strut against folding. The upper and lower portions of the strut are axially aligned (C, F) when the strut is in a fully-deployed position and the locking brace (42, 44/84, 86) maintains the strut portions (14, 16/62, 64) in this axially-aligned position. The locking brace (42, 44/84, 86) is releasable to allow relative folding movement of the upper and lower portions (14, 16/62, 64) for retraction of the strut to a stowed position. An actuation/locking mechanism (106) is provided to maintain folding members (42, 44/84, 86) of the locking brace in an axially-aligned, locked position and to displace members (42, 44/84, 86 ) of the locking brace from the axially-aligned position for retraction of the gear (10, 12).
