ABSTRACT:
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.
