Abstract

A review of the existing rain erosion test capabilities has shown that it is difficult to obtain multiple waterdrop impacts on materials over an extended range of supersonic velocities which are both well-documented and at moderate cost. Recognition of this deficiency motivated the development of a facility located at General Research Corporation (GRC) in Santa Barbara, CA to provide controlled multiple1 simulated waterdrop impact conditions for impact velocities from 300 to 1700 ms (up to Mach 5). A collection of particles, selected for their capacity to simulate waterdrop impact damage, are propelled at the target using a 50 mm powder gun. The development and anticipated capability of this facility is described. A discussion is then presented of the planned test program designed to formulate and validate damage models for electromagnetic (EM) window materials in the supersonic flight regime.
