摘要:
Control link (600) for an aircraft (101, 201) comprising an impact-resistant structure with a redundant load path. The control link (600) has an inner structure (602) that is sized to carry the anticipated load of the flight control system and to meet all safety factors. The control link (600) also has an outer structure (601) that is sacrificial and configured to absorb impact damage during operation, thereby protecting the inner structure (602). The outer structure (601) is also designed to carry the anticipated load of the flight control system on its own, independent of the inner structure (602), and to meet all safety factors. If the outer structure (601) fails, the inner structure (602) allows for continued safe operation of the flight control system. The space or cavity (604) between the inner and outer structures (601,602) may be filled with a material, such as a closed-cell foam, to improve the impact resistance of the outer structure (601).
