A pneumatic deicer includes a base layer, a forming layer, a first chamber, and a first sensor. The base layer has an inlet, a first side, and a second side. The forming layer is connected to the base layer along at least two seams and has inner side and an outer side with the outer side being distant from the base layer. The first chamber is formed between the base layer and the forming layer and configured to be inflated by air passing into the first chamber through the inlet in the base layer. The first sensor is situated within the first chamber.

A method for protecting an aircraft component from ice formation uses a thermally conductive film. The film includes a polymer, an electrically conductive material, and a sufficient concentration of hexagonal boron nitride to provide adequate heat transfer properties, and have high thermal conductivity, peel strength, and shear strength. The films can include thermoset polymers, thermoplastic polymers, or blends thereof, and can also include reinforcing materials such as fiberglass, carbon fiber, metal mesh, and the like, and thermally conductive fillers, such as aluminum oxide, aluminum nitride, and the like. The films can be included in composite materials. The films can be used as part of a layered structure, and used in virtually any application, for example, various locations in aircraft, where heating is desirable, including nacelle skins, airplane wings, heated floor panels, and the like.

An electrothermal deicing apparatus includes at least one heater conductor formed into a predetermined pattern for application to a structure. Each conductor of the pattern is coated with at least one layer of a material active to absorb electromagnetic energy. The pattern of the at least one coated heater conductor is operative to attenuate radar wave transmissions incident thereon to reduce the radar cross-section of the structure. A heater controller is coupled to the pattern of at least one coated heater conductor for controlling the deicing of the structure.

A radar altering structure comprises: a structure; and at least one layer of conductive material disposed at at least one surface of the structure, the layer comprising a plurality of conductive paths arranged in a specular pattern to reduce the radar cross section of the structure.
