Abstract
A sealing system for an aircraft having an opening and a door movable between an open condition spaced from the opening and a closed condition covering and sealing the opening includes a cover plate connected to the aircraft adjacent the opening. A first magnetic coupling secured to the cover plate includes a first plurality of magnets. A second magnetic coupling configured for securing to the door includes a second plurality of magnets. The first magnetic coupling is repelled by the second magnetic coupling when the couplings have a first degree of alignment with one another. This causes the cove plot move away from the door. The first magnetic coupling is attracted to the second magnetic coupling when the couplings have a second degree of alignment with one another greater than the first degree, causing the magnetic couplings to engage one another and seal the opening in the aircraft.
