A pneumatic deicer having a deformable sheet formed of a fluid-impervious, resilient material adapted to be secured with respect to the leading edge of an aircraft wing. A rigid template with spaced, parallel apertures is secured to the face of the deformable sheet remote from the aircraft wing. The regions of the deformable sheet corresponding to the apertures form fluid passages adapted to be coupled with a source of fluid such as air so that the deicer may be cyclically expanded and contracted to break up ice accumulations on the deicer. A cover ply is secured to the outer face of the deformable sheet to expand and contract therewith and to add wear resistance to the deicer. The periphery of the inner face of the deformable sheet may be secured to the leading edge of the aircraft wing through an inner or base ply or, in the alternative, it may be secured directly thereto without the inclusion of the inner or base ply.

A pneumatic deicer adapted to be secured to an airfoil surface and which has a plurality of expansible and contractible portions for breaking up and removing accumulated ice, said deicer including: a deformable sheet of fluid impervious resilient material; a rigid template secured to the outer face of said deformable sheet, said template having apertures corresponding to the plurality of expansible and contractible portions of said deicer which apertures allow deformations therethrough of said sheet; the remaining regions of said template restraining deformation of said sheet; and means to couple said deicer to a source of fluid such that when fluid is introduced to, and evacuated from said deicer, said deicer will expand and contract said plurality of expansible and contractible portions.
