GAM-87A RAIN EROSION PROTECTION COATINGS FOR SUBSONIC SPEEDS

Abstract

High velocity contact with raindrops causes a severe erosion problem on phenolic materials. The following test was run to determine the most suitable coating for protection of the thermal insulation material on the GAM-87A re-entry vehicle from rain erosion. Specimens made from Phenolic Refrasil and Phenolic Nylon, both coated and uncoated, weathered and unweathered, were tested at a velocity of 500 mph on two rotating, electrically driven propeller blades through a simulated rainstorm of 1 in./hr intensity and with drops of 2 mm average diameter.
