Methods and apparatus for reacting rotary actuator and control surface loads into a wing structure using reaction links. The apparatus incorporates a structural interface feature that can facilitate a change of the component(s) in the load loop, such as the path connecting a control surface to a fixed aircraft structure via a rotary actuator. In particular, the structural interface between the rotary actuator and the rear spar of a wing can be tuned for stiffness to achieve an optimized load path that reacts actuator and control surface loads back into t...
1. An apparatus comprising: an aircraft structure;first and second hinges coupled to said aircraft structure;a control surface coupled to said first and second hinges;a rotary actuator comprising a housing and an output shaft rotatable relative to said housing, the output shaft being coupled to said control surface for causing pivoting of said control surface about a hinge line;a first reaction link having a first end rotatably coupled to said housing of said rotary actuator for transmitting reaction forces to said aircraft structure during pivoting of s...
