초록

A variable camber flap assembly having first and second operative positions. A rotatable drive arm powers first and second linkage subassemblies. The first linkage subassembly extends the flap panel in a downward and forward direction to its operative positions, and also rotates a hinged bullnose outwardly so as to foreshorten the distance between the leading and trailing edges of the flexible flap panel, increasing the camber of the flap. The second linkage subassembly cooperates with the first to angularly orientate the flap panel in its operative posi...
