ABSTRACT:
The thermal protection device comprises, for at least one elastomeric component of a rotor, at least one element which is fitted onto the rotor so as to reduce heat exchange between the elastomeric component and the ambient air. The element may be thermally insulating and may include at least one layer of a thermal insulation material and means for fitting it onto a metal reinforcement of the elastomeric component so as to cover its free surfaces, which are exposed to the ambient air, and/or at least one deflector sheltering, at least partially, a laminated part of the elastomeric component from the relative wind in order to reduce forced convection.
