Abstract

To better understand the mechanism by which materials passing through rain at supersonic speeds are damaged the results of numerous types of impacts on metals were analyzed. An equation which relates total energy of impact to the volume of metal displaced was derived and found adequate to explain damage in the velocity range from less than one foot per hour to greater than Mach 3. This equation together with results of incidence angle tests led to an overall damage equation which was successfully applied to the problem of multiple drop rain damage. Principal parameters are target material tensile strength; impacting material shape and mass; angle of incidence; and the velocity of impact. Facility improvements and test method refinements are described.
