Description: Special Report
Abstract: Soil samples, collected at proving grounds, test sites and paratroop training areas, were examined in an attempt to estimate their potential abrasive properties when in contact with parachute support lines. Portions of support lines that had been invaded by grit during strain tests were also examined to determine the properties of the particles that degraded the lines. These preliminary analyses indicate that soil particles of a size comparable to that of the individual filaments of the parachute cord infiltrate to the interior of the cord, become embedded and damage the cord. It is necessary to determine some additional soil properties, most importantly effective hardness ofthe individual grains, to establish a general description of performance degradation.
