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.
