Abstract
A load hook substructure for attachment onto or into the cabin structure of a helicopter, having a housing in which a shaft with a hook attachment is mounted, such that a load hook can be connected with the shaft and thereby with the load hook substructure; this improves the flying characteristics of the helicopter in the case of flights with a load carried underneath. This is achieved in that the shaft passes through the interior of the housing in the longitudinal direction between a housing end wall and a housing wall, such that it can move linearly, and a return spring device is arranged between a damping plate arranged on the shaft and the housing end wall, and a damping device is arranged between the damping plate and the lower housing wall. The damping device has at least one flexibly compressible damping element, which develops a damping action in the event of a linear movement of the shaft.
