Thermal protection device of the elastomer elements, a set of such devices for the protection by cold weather of a rotorcraft rotor, and of a rotorcraft rotor relates to such an assembly

摘要

The guard forms a heat barrier (30,40) for the elastomeric rotor coupling (10,16) on the rotor hub. The barrier is mounted on the rotor to prevent heat exchange between the coupling and the ambient air. The guard forms a layer of insulating material (30) with mountings (34,42) for mounting on the coupling and partially cover it.
