This Test Track Rain Simulation Facility extends over one rail of the 50,000 ft track in sections of 400 ft length up to a total length of 18,000 ft. An overview of the physical layout, control set-up, test set-up and test instrumentation is given. Performance data expressed in terms of drop number distribution over eight drop size classes from 0.5 to 4 mm, equivalent rain rate, liquid water content, and median mass diameter are presented and, the constants of a least square exponential approximation to drop size distribution are included for nine rows of sample volume locations. Also included are graphs for the estimation of the number and size of drops encountered by a test specimen moving through the rain field.
