Electromagnetic Detection of Surface Icing

Development is proposed for a breakthrough technique involving the use of electro-magnetic radiation to detect and measure thickness of non-conductive coatings on both metallic and non-metallic surfaces. The primary objective of the Phase I effort will be to prove that this approach can detect all forms of ice on aircraft structures and roadway surfaces. This system would permit detection and measurement under the various metrological conditions which produce icing and is further capable of detecting ice which is covered or co-mingled with snow, sleet, or rain. Mathematical analysis and recent experimentation indicates that the proposed technique will far exceed the capabilities of existing detection methods, as well as those known to be under development. Applicable to both military and commercial aircraft, this proprietary approach would also operate with newer aircraft having structures made of composite materials. Accurately determining when and how much de/anti-icing fluid is needed would offer significant cost savings and decrease environmental impact. The ability of this technique to precisely meausre the thickness of a non-conducting material could be used in many process control applications, as well as painting and bonding operations. Possibly dangerous surface corrosion could also be detected. Anticipated Benefits: Improved air and highway transporation safety, reduced environmental pollution and significant potential for economic savings. Broad application in the manufacturing sector in the areas of quality and process control, related to coatings and thickness measurements.
