System for latching and locking a foldable airfoil

摘要

An aircraft comprises a foldable airfoil. The airfoil includes inboard and outboard sections that are hinged together about a hinge line. The airfoil further includes a first latching mechanism on an inboard side of the hinge line, and a second latching mechanism on an outboard side of the hinge line for latching the outboard section to the inboard section.

1. A foldable airfoil apparatus comprising:
inboard and outboard sections that are movable about a hinge line; and a hinge assembly to hinge the inboard and outboard sections, the hinge assembly defining the hinge line, the hinge assembly including:
a torque box;a first latching mechanism on an inboard side of the hinge line, the first latching mechanism including a first retractable latch pin actuator positioned entirely within the torque box; anda second latching mechanism on an outboard side of the hinge line, the second latching mechanism including a second retractable latch pin actuator positioned entirely within the torque box, the first and second retractable latch pin actuators to actuate the first and second latching mechanisms to latch the inboard and outboard sections when the outboard section is in a deployed position.
