1. A device for detecting and preventing the formation of ice on contoured surfaces, comprising:
- a rigid hollow support structure including a contoured surface;
a deformable wall covering said contoured surface;
means for providing an airtight securement between said support structure and said deformable wall along a plurality of lines of contact, whereby a plurality of elementary chambers are defined by said support structure, said deformable wall and said means for providing an airtight securement;
at least one first opening between the interior of said support structure and each of said elementary chambers;
at least one opening in said deformable wall at each said elementary chamber; and
means for feeding hot gas to said interior of said support structure.

Abstract
In a device for breaking up ice formed on a contoured surface before it reaches a dangerous thickness, a flexible and porous membrane is fixed on the contoured surface along airtight lines of contact defining elementary chambers, each of which communicates with a main chamber inside the contoured surface. The main chamber is fed continuously by a source of hot gases. The closing up of the pores of the membrane by ice causes an inflation of the elementary chambers and a deformation of the membrane. Application is to the cowl of the air intake of a turbojet engine and to a detector used for the control of a de-icing device of any type.
