|Abstract:|| The Nuclear Hardness Database System (NHDBS) is a planning tool that predicts safe escape distances for platforms capable of nuclear weapon delivery. This research attempts to fulfill a portion of the NHDBS update involving thermal irradiation of aircraft coatings, in this case F-16 paint. The paint was irradiated using the Air Force Institute of Technology (AFIT) Xenon Thermal Simulator (AXTS). Nano indention and spectrophotometric reflectance measurements were made both pre- and post-irradiation to quantify changes due to the increased temperature of the paint.
Sample irradiations varied from no visible damage to complete pyrolysis of the surface. Nano indentation measurements did not have any change until the onset of pyrolysis for aluminum alloy 2024 samples with paint thicknesses of 3 mils and 18 mils. The reflectance measurements provided the best quantitative data; however, the pyrolysis pattern on the surface influenced the measurements. The 3 mil paint samples tended to have uniform pyrolysis while the 18 mil samples showed pyrolysis centered on the highest flux portion of the AXTS beam.
