This report discusses the rain erosion resistance of various coatings used as protection on radomes, aerial covers and metallic leading edges. Specialised applications such as the erosion problems connected with air cushion vehicles are also included. Most of the tests were conducted under standard conditions of 500 mileh in 1 inh simulated rainfall but some results at lower speeds are listed. The best erosion resistance was obtained with stainless steel, but some polyurethane sheet materials also gave excellent protection, provided that a good adhesive bond to the substrate had been obtained. A form of polyurethane self-adhesive tape gave protection to an intermediate degree and had the added advantages of ease of application and replacement when necessary. Author
