Abstract
Two sets of filaments (38, 72) are mounted on opposite sides of a discontinuity (6) between a movable or removable panel (4) and adjacent outer skin portions (2) of an aircraft. The filaments (38, 72) have retracted positions in which they are out of engagement with each other. With the filaments (38, 72) retracted, the panel (4) is moved into its use position flush with the outer surface of the skin (2). The filaments (38, 72) are then extended into the discontinuity (6) by a mechanism, such as a cam-ratchet (44) or an inflatable bladder (68). The extended filaments (38, 72) interdigitate to seal the discontinuity (6) and simulate a solid surface across the discontinuity (6).
