Abstract
An end seal (36) for a variable camber flap in which the seal is formed of an upper portion (52) including closely spaced fingers (56). The fingers extend generally vertically downwardly from adjacent a flexible surface (40) of a flap (20). There are lower sealing walls (94, 96) extending generally vertically upwardly from adjacent the bottom of the flap (106). The lower sealing walls are adapted to remain in sealing engagement with the fingers as the camber of the flap is varied by increasing the curvature as it is lowered from a normally upper position.
