A deicer is provided for breaking up and removing accumulated ice on an airfoil surface. The deicer includes a bondside surface that is bonded to the airfoil surface, a breezeside surface on which the ice will accumulate, and passage-defining surfaces therebetween. The passage-defining surfaces define a plurality of expansible and contractible inflation passages and include a moisture-impervious coating whereby moisture within the inflation passages will not be absorbed by the surfaces. The bondside, breezeside and passage-defining surfaces may be contained on a deicer panel and means may be provided for introducing inflation fluid to and evacuating inflation fluid from the passages to expand and contract the inflation passages to break up and remove the accumulated ice.

Deicer for aircraft

A deicer ( ) for a radome ( ) includes an active portion ( ) through which transmission occurs and a non-active portion ( ) which is attached to an aircraft ( ). The deicer ( ) comprises a cap portion ( ) covering the active portion ( ) of the radome ( ) but unattached thereto. The cap portion ( ) comprises layers ( ) defining inflatable/deflatable chambers ( ), the layers both being made of non-extensible material such as square woven nylon fabric. When the chambers ( ) are inflated, the inner layer ( ) lifts off of the active portion ( ) of the radome ( ). The deicer ( ) can additionally comprise a skirt portion ( ) which is stretchable to accommodate the inflation of the chambers ( ).
