Abstract
The invention is illustrated by two embodiments of an aircraft landing gear manual release assembly each comprising a sequential main gear mechanism (MGM) for sequential release of port and starboard main door uplocks (MDU) followed by release of port and starboard main gear uplocks (MGU) and a sequential nose gear mechanism (NGM) for sequential release of a nose door uplock (NDU) followed by release of a nose gear uplock (NGU). The assemblies are characterized by a single control handle actuator (CHA) for movement from a gear stowed position to a gear deployed position for sequential actuation of the main gear mechanism (MGM) followed by actuation of the nose gear mechanism (NGM) through cable assemblies (20 or 120) and (22 or 122). The single control handle actuator (CHA) includes a single control handle (30 or 130) and a first support bracket (31 or 131) movably supporting the control handle (30 or 130) and a lost motion member (32 or 132) movably supported by the first support bracket (31 or 131). The control handle actuator (CHA) further includes a first lost motion connection (33 and 34 or 133 and 134) between the control handle (30 or 130) and the lost motion member (32 or 132) whereby the control handle (30 or 130) first moves the first cable assembly (20 or 120) and upon continued movement thereof moves the lost motion member (32 or 132) to subsequently move the second cable assembly (22 or 122) for the sequential actuation of the main gear mechanism (MGM) followed by actuation of the nose gear mechanism (NGM).
