Abstract:

This report describes the procedures and results from dust cloud testing performed by Midwest Research Institute MRI in support of the DARPA Sandblaster I testing program. The testing was conducted at the La Posa drop Zone of the Yuma Proving Ground YPG during three periods in February through April 2006. MRIs objective was the characterization of brownout dust clouds generated by six rotorcraft airframes UH-1, CH-46, CH-53, V-22, HH-60, and MH-53. The primary MRI measurement parameters were dust intensity concentration and particle size distribution. All airframes were tested in a hover-taxi maneuver, except for the V-22, which was also tested during landing. The soil beneath the flight path was tilled before testing to maximize the dust emission potential. The MRI sampling array was deployed at fixed positions on the center-line of the flight path and downwind along the rotor-tip path and at distances of 18 m and 35 m downwind of the rotor-tip path. This deployment was used to characterize the brownout cloud formation and transport phenomena.
