Abstract
The invention concerns laminated stops of curved shapes, particularly for helicopter rotors. The stop has an inner fitting and an outer fitting connected by cupped elements of a resistant and rigid material alternating with layers of flexible material. The layers of flexible material increase in thickness from their centers outwardly, and the mean thickness of the flexible layers increase from the inner fitting to the outer fitting.
