- a multiple of elastomeric material layers;
- and
- a multiple of shim layers, each of said multiple of shim layers between two of said multiple of elastomeric material layers, at least one of said multiple of shim layers includes an electrically heatable shim layer.
A rotor system comprising:
- a first rotor system member;
- a second rotor system member;
- and
- an electrically heatable elastomeric bearing mounted to said first rotor system member and said second rotor system member, said electrically heatable elastomeric bearing comprises:
- a multiple of elastomeric material layers;
- and
- a multiple of shim layers, each of said multiple of shim layers between two of said multiple of elastomeric material layers, at least one of said multiple of shim layers includes an electrically heatable shim layer.
4 more elements
A method of warming-up an elastomeric bearing comprising the steps of:
- (A) electrically heating at least one electrically heatable shim layer spaced between at least two of a multiple of elastomeric material layers of the elastomeric bearing.
