A single impact rain erosion test capability has been developed to obtain data on fiber loaded Teflon e.g. Duroid ablative radome materials at temperatures up to their ablating temperature approx. 1250 F. This effort was undertaken as a result of the prior inability to 1 obtain experimental data for single water droplet impacts on these materials at temperatures significantly above 400 F at velocities near Mach 5, and 2 identify a solid particle whose behavior is similar to or can be correlated to that of water droplets at all conditions of interest. This test capability allows one to dispense a stream of calibrated discrete water droplets in the path of aerodynamically heated samples on sleds at velocities up to 6000 ftsec.
