Folding helicopter rotor blade, with folding pivot, electric cable and spiral cable container

摘要

The rotor blade (17) has a folding pivot (21) so that the blade can fold round a folding axis (39) running transversely to the length of the blade, with an electric cable (25) running along the blade and extending over the folding pivot. A spiral cable container (33) is fitted to the folding pivot to take a coil of cable.
