1. A method for deicing a substantially high modulus ice accreting surface upon which ice accumulates comprising the step of:

  • periodically activating beneath the ice accreting surface at least one inflatable member means of a size, position, and physical configuration such that activation of the inflatable member distorts the ice accreting surface placing chord-wise strain upon substantial portions of the ice accreting surface to an extent sufficient to produce periodic desirable distortion and chord-wise strain in the ice accreting surface sufficient to release accumulations of ice thereon;

    activation being accomplished to the sufficient extent in not more than 0.250 seconds.
