Jet Blast Tests on Fiberglass-Reinforced DCA-1295.

摘要

This report describes an effort to evaluate a dust-control system consisting of DCA-1295 reinforced with fiberglass scrim when subjected to jet blast tests with associated wind velocities in the range of those caused by operating C-5A aircraft. A sand panel and two clay panels were treated with DCA-1295 and reinforced with fiberglass scrim and found to withstand air blast velocities greater than 125 mph. It was recommended that the dust-control system be tested for the heavy-lift helicopter and that additional testing under actual C-5A operations be conducted using multiple layers of the dust-control materials.
