Airflow-dependent deployable fences for aircraft wings are described. An example apparatus includes a fence of a wing of an aircraft. The fence includes a base that is coupled to the wing and a panel that is movable relative to the base and the wing between a stowed position in which the panel extends along a skin of the wing, and a deployed position in which the panel extends at an upward angle away from the skin. The panel is configured to impede a spanwise airflow along the wing when the panel is in the deployed position. The panel is configured to move from the deployed position to the stowed position in response to an aerodynamic force exerted on the panel.

The fence is configured to move from the stowed position to the deployed position in response to an aerodynamic force exerted on a deployment vane of the fence.

Automated deployable fences for aircraft wings are described. An example apparatus includes a fence, a latching actuator, and a biasing actuator. The fence is coupled to a wing of an aircraft. The fence is movable relative to the wing between a stowed position in which a panel of the fence extends along a skin of the wing, and a deployed position in which the panel extends at an upward angle away from the skin. The panel impedes a spanwise airflow along the wing when the fence is in the deployed position. The latching actuator is movable between a first position in which the latching actuator maintains the fence in the stowed position, and a second position in which the latching actuator releases the fence from the stowed position. The latching actuator moves from the first position to the second position in response to a control signal received at the latching actuator. The biasing actuator moves the fence from the stowed position to the deployed position in response to the latching actuator moving from the first position to the second position.
