Abstract
A deicing system for an aircraft engine (4) having blades (14, 16) fixedly attached to rotating propulsors (6, 8) has emitters (22, 28) which irradiate microwave beams (24, 26, 30 32) onto coatings (18, 20) which are fixedly attached to said blades (14, 16). Substantially more of the energy of the beams (24, 26, 30, 32) is absorbed by the coatings (18, 20) than by any water or ice on the blades (14, 16) causing any ice which is on the blades (14, 16) to be thrown off by the centrifugal force of the rotating propulsors (6, 8).
