Abstract
A wing fold actuation system (24) is provided for folding an outboard wing section (18) relative to an inboard wing section (16) between a deployed position (20) and a stored position (22). The system (24) includes an actuator (26) in the form of a geared rotary actuator (30) in combination with a four-bar linkage (32). A locking mechanism (28) is provided to lock the outboard wing section (18) in the deployed position (20), and includes a catch on the outboard wing section (18) that is engageable with a rotary latch (42) on the inboard wing section (16). A timing transmission (46) connects the rotary actuator (30) with the rotary latch (42) to time the rotation of the rotary latch (42) with respect to the movement of the outboard wing section (18) between the deployed and stored positions (20,22).
