Paper Abstract

In flight, infrared domes must withstand heating and mechanical siresses. Therefore, the rain erosion resistance to be considered in predicting the lifetime of the dome must be different from the one usually measured in ground test facilities without these environmental conditions. The purpose of the present study was to measure the effect temperature and stress have on the erosion resistance of materials. A ground test facility was used that was modified to create these environmental conditions. Special supports and electronics were designed and made to heat and bend the samples. Significant variations occur in material resistances as a result of temperature, while the effect of stresses seems to be catastrophic.
