Pneumatic deicing device for breaking and removing an ice deposit accumulated on the outer surface of an aircraft

A pneumatic deicing device (1) for breaking and removing an ice deposit accumulated on the outer surface (2) of an aircraft, comprising, from the outside in:

• an outer layer (10) defining an outer surface of the deicing device and formed from a material selected to withstand an outside environment,
• at least an outer intermediate layer (30) and an inner intermediate layer (40) connected to one another by a network of stitches (36) spaced apart so as to define deicing chambers (35) that can be inflated quickly using injected pressurized air so as to create an expansion of the device (1) causing a mechanical action to break the ice, and
• an inner interface layer (50) that includes at least one textile layer (54) situated farthest toward an inner side of the deicing device (1) and the at least one textile layer (54) has an inner surface (55) for direct contact with the outer surface (2) of the aircraft, the inner interface layer (50) being spaced from the stitches (36).
