Cable connection arrangement for helicopter rotor blade de-icing circuits, uses flexible aerial (flying) connections between articulating mechanical-linking components, with cable section transformed form circular to flat section

摘要

Cable connection between the hub (2) on the drive mast (1) and the rotor blade (3') is split into four sections. The first section (31) comprises armored cable (18) delivering current via mast connector (24) to an adapter (33') transferring cable section from circular to thin rectangular form. The second section (30') comprises flat cable (32) in a loop attachment over the first aerial (flying) connection to an articulated element (34) allowing pivoting and angular change of the cable with respect to the support arm (5'). The flat cable continues outward along the arm (5') and is transposed vertically by the connector (49) to provide the second aerial link between the arm (5') and the blade (3') using the yoke mount assembly (51). The fourth section (42) has an armor covering and circular form, entering the blade at the blade connector (43).
