Abstract
An externally mounted aircraft fairing arrangement for mounting on an aircraft wing that has a hingedly displaceable control surface, such as an aileron, includes a first fairing portion (11) on the wing aircraft structure and a second fairing portion (12) located on the control surface, bridged over by an intermediate flexible seal arrangement. The flexible seal arrangement (13) comprises a plurality of slidably overlapping layers (16) of longitudinally extending fingers (16a, 16b) on the fixed fairing portion (e.g. 11) and overlapping and slidably engaging the other fixed fairing portion (e.g. 12). The fingers (16a, 16b) of the layers lie in laterally staggered relationship with respect to each other such that in operation they can accommodate differential movement between the fairing portions (11, 12) when the control surface is angularly displaced relative to the fixed structure.
