Abstract
An aircraft flap (or slat) drive apparatus includes first and second centralized drive units that respectively rotationally drive first and second drive lines in both wings. The first drive line includes shaft segments connected end-to-end by selectively engageable separating devices. The outboard ends of the first and second drive lines are coupled through one of the separating devices, in each wing. At least one actuator mechanism connects each flap to a respective shaft segment of the first drive line, and converts the drive line rotational motion to a flap translational motion. If a component breaks, jams, or otherwise fails, it is isolated by disengaging the two adjacent separating devices with the faulty component therebetween, so that the rest of the apparatus remains functional. Each one or both of the drive units can drive one or more or all of the flaps through the interconnected first and second drive lines.
