Laboratory Investigation of Chemical Dust Pallative Performance on Sandy Soil
The U.S. Army and Marine Corps initiated a search for chemical dust palliatives for mitigating dust on helipads. The purpose of this investigation was to evaluate the effectiveness of current technologies for suppressing dust caused by rotor wash during helicopter landings. The study used an air impingement device to simulate wind speeds similar to field conditions. Chemical dust suppressants were applied topically to prepared soil specimens and allowed to cure for 1 and 48 hr. Effectiveness was determined from the relative weight loss of the soil samples from erosion during the test procedure. An optical sensor was installed in the test device to provide an additional method for quantifying performance.
